    Full Text Available This work describes the phenology of Spalangia endius Walker in pupae of Musca domestica Linnaeus under laboratory conditions. In order to understand the developmental cycle of Spalangia endius under laboratory conditions, 360 Musca domestica pupae aged from 24 to 48 hours were exposed to 15 S. endius pairs for a period of 24 hours at 26 ± 2ºC. These pupae were kept in a BOD incubator at the same temperature, with a relative humidity of Objetivando conhecer o ciclo de desenvolvimento de Spalangia endius sob condições de laboratório, 360 pupas de Musca domestica com idade de 24 a 48 horas foram expostas a 15 casais de S. endius por um período de 48 horas a 26 ± 2ºC. Estas pupas foram mantidas em BOD. Com mesma temperatura, umidade relativa <70% e com fotofase de 12 horas, onde diariamente dissecava-se 15 espécimes para avaliar o estágio e tempo de desenvolvimento do himenóptero. A fenologia permite concluir que S. endius apresenta um ciclo de desenvolvimento de 19 dias, cujo período de incubação foi de 24 horas, o desenvolvimento de larvas de S. endius ocorreu nos oito dias subsequentes nos quais uma série de alterações morfológicas foi observada. O estágio de pré-pupa deu-se no décimo dia onde cessa a movimentação e inicia a eliminação de mecônio. O estágio pupal ocorreu do décimo primeiro dia ao décimo nono, momento da emergência dos primeiros machos, já as fêmeas iniciaram a emergência aproximadamente 24 horas após. Estes resultados permitem avaliar aspectos da bionomia pormenorizada do desenvolvimento de S. endius para armazenar e programar a produção deste parasitóide, otimizando sua utilização como agente de controle biológico.

    The knowledge of the fauna associated with carrions and cadavers for a specific region plays a fundamental role in the estimation of the time since death in forensic cases. In the last years global warming and globalization have affected the insect species distribution. This phenomenon is affecting also the species of forensic interest associated with the cadaver decomposition. The species distribution shift, in the forensic context, has been mainly observed in Diptera of different family: Calliphoridae, Stratiomyidae and Phoridae. In the last decade the presence of the carrion feeding species, Synthesiomyia nudiseta (Diptera: Muscidae), was reported from forensic cases in Spain and in the last year from Italy where the species was collected from 5 bodies in different decomposition stages in the Genoa district. All the records concern indoor cases with the presence of other species belonging to the first colonization waves (e.g. Calliphoridae, Sarcophagidae). Different hypothesis about the presence of the species in Italy can be suggested, but the molecular analysis and the importation records support the introduction trough commercial exchanges with Asian countries instead of a variation in the species distribution area from the Iberian Peninsula.

    The house fly, Musca domestica L. (Diptera: Muscidae), is a disease vector of mechanically transmitted pathogens including bacteria, viruses, and protozoans. Opportunities for pathogen transmission can increase as fly longevity increases. Dietary preferences play an important role in insect longevity; therefore, we investigated house fly preferences, sucrose availability, and caloric constraints on house fly longevity. Experimental goals were: 1) to test the effects of calorie restriction on survival of house flies by manipulating concentrations of erythritol (low caloric content) and sucrose (high caloric content), and comparing commercial sweeteners of differing calorie content, 2) to identify house fly preferences for either erythritol or sucrose, and 3) to evaluate the insecticidal activity or toxicity of erythritol on house flies. Our data show that house flies may prefer high calorie options when given a choice and that house fly longevity likely increases as calorie content increases. Additionally, no significant differences in longevity were observed between the water only control (zero calories) and erythritol treatments. This suggests that decreased survival rates and death could be the result of starvation rather than insecticidal activity. This research furthers our understanding of house fly survival and sugar-feeding behavior. © The Authors 2017. Published by Oxford University Press on behalf of Entomological Society of America.

E-mail: camilamendes1009@gmail.com Stomoxys calcitrans fly is one of the dipterans of importance for livestock farming due to the considerable economic losses it determines worldwide. An aspect that favors the occurrence of this insect's outbreaks in Brazil is the generation of large quantities of by-products from the alcohol industry, such as vinasse, sugarcane straw, bagasse, filtercake and ashes. The present study aimed to evaluate the possible interference of vinasse and ashes on the immature stages of S. calcitrans, by comparing the biological parameters observed with or without the presence of these substrates. In Experiment I, three groups of 50 eggs were deposited in a diet composed of one kilogram of chopped cane and 250mL, 500mL and 1L of vinasse (groups 1, 2 and 3. In the control groups, distilled water was added to the chopped cane in the same proportions used in the groups treated with vinasse. In Experiment II, three groups of 50 larvae from eight to 10 days of emergence were deposited on a diet composed of cane, vinasse and ashes. The ashes were used in the proportion of 1, 2 and 3% (groups 1, 2 and 3 of sugar cane (100g and vinasse was used in the proportion of 100mL for all groups and their respective controls. The control group contained only sugarcane and vinasse. Both experiments were kept in a climatized chamber (27 ± 1°C and 70-80% RH, and three replications were performed.

Isto foi verificado para 160 casais de Muscina stabulans (Fallén, 1817 mantidos em câmara climatizada a 24,8ºC ± 0,6ºC, umidade relativa do ar entre 70 e 80% e fotofase de 12 horas. Nestas condições, machos e fêmeas apresentaram valores de H intermediários aos valores teóricos de H = 0 e H = 0,5 demonstrando que para esta espécie, a curva de sobrevivência é do tipo retangular. A distribuição da mortalidade por idade específica indicou que a força desse parâmetro age de dois modos sobre os adultos desta espécie. Em um, a mortalidade tem maior força nos intervalos compreendidos entre a emergência dos adultos e o 10º dia após este processo. No segundo modo, a força de mortalidade é maior entre o 20º e 30º dias após a emergência, sendo que pequenas variações na mortalidade causam maior impacto na sobrevivência das fêmeas do que nos machos.Entropy estimation in Muscina stabulans (Fallén (Diptera, Muscidae under laboratory conditions.

    House flies, Musca domestica L., (Diptera: Muscidae), are pests of poultry and have the ability to develop resistance to insecticides. To design a strategy for resistance management, life history traits based on laboratory observations were established for lambda-cyhalothrin-resistant, susceptible and reciprocal crosses of M. domestica strains. Bioassay results showed that the lambda-cyhalothrin-selected strain developed a resistance ratio of 98.34 compared to its susceptible strain. The lambda-cyhalothrin-selected strain had a relative fitness of 0.26 and lower fecundity, hatchability, lower number of next generation larvae, and net reproductive rate compared with its susceptible strain. Mean population growth rates, such as intrinsic rate of population increase, and biotic potential were lower for the lambda-cyhalothrin-selected strain compared to its susceptible strain. Resistance to lambda-cyhalothrin, indoxacarb, and abamectin was unstable while resistance to bifenthrin and methomyl was stable in the lambda-cyhalothrin-selected strain of M. domestica. Development of resistance can cost considerable fitness for the lambda-cyhalothrin-selected strain. The present study provided useful information for making potential management strategies to delay resistance development in M. domestica.

    Full Text Available House fly (Musca domestica is an important urban insect that can transmit various infectious diseases. This insect usually utilized organic wastes as nutrition source for their larvae. One of the main sources of organic wastes is livestock manure produced by animal farming located near human dwelling area. Thus, appropriate house fly population control program at animal farm is needed,based on information on the house fly’s life history. The research is focused on the development of house fly larvae reared with different livestock manures, such as cow, chicken, and horse. As comparison, rice bran were used as control. Results showed that larvae reared with horse manure has the shortest development time (5 days, with lowest larval survival rate (30%, pupal weight (6.8 ± 0.141 g, and weight of female imago (4.9 ± 0.14 g. This finding indicates the lowest nutrition value of horse manure for house flies larvae. Further research is needed to find the effect of manure to variables that directly influence population growth, such as fecundity of female flies and egg survivorship. These additional information on life history will help the design of appropriate house fly population management program for animal farm.

Here we address the developmental period of immatures stages and their viability. To obtain eggs, larvae and pupae, a colony was established in the laboratory. Adult flies were fed on a diet comprising two parts dry milk, two parts sugar and one part fish flour. Larval diet comprised one part fish flour and one part sawdust and water. The eggs, larvae and pupae were incubated at 26º ± 1ºC, 75% ± 10% R.H. and 12 h photoperiod. The egg to adult cycle took 573 h with a total viability of 64%. The shortest of the stages was the egg stage, which lasted about 20 h. The larval stage had the lowest viability (about 82% and longest time interval (279 h. Overall, the results of this study show that O. albuquerquei can be readily maintained in the laboratory.

    Abstract. Cariocamyia maculosa Snyder, is a muscid fly with records from Colombia and Brazil (Southern, Southeastern and Central-West regions. In a survey of Diptera saprophagous in Feira de Santana, state of Bahia, with animal organic bait were collected 46 specimens of C. maculosa. This is the first record of the species to Bahia and Northeastern of Brazil. The forensic importance and the anthropized status of C. maculosa have not been detached in the specialized literature and new studies should be improved to corroborate these conditions.

    Full Text Available Bermudagrass (Cynodon dactylon cv. Jiggs is an important food source for dairy cattle in the semi-intensive milk production systems most often used in southern Brazil. Although many insect pests are associated with feed grasses, we report here the first occurrence of the fly Atherigona (Atherigona reversura Villeneuve, 1936 (Diptera: Muscidae feeding on bermudagrass in Brazil. This potential pest was observed in April 2015 in three localities (Abelardo Luz, Palmitos, and Videira in western Santa Catarina, in southern Brazil. The infested plants had senescent and necrotic terminal leaves that reduced plant growth. New growth had to sprout new tillers from basal nodes, which resulted in a reduced plant growth rate. We also provide a morphological identification key (with figures for A. (Atherigona reversura and A. (Acritochaeta orientalis Schiner, 1868. A molecular identification based on COI is also provided to better differentiate species. Keywords: COI gene, Insect pest, Pastures, Plant–insect interaction

    The discovery of dipteran remains on mummified individuals can lead to either cause for curatorial concern or to a better understanding of the individual's post-mortem environment. The present study analyzed insect remains associated with the body of a unique medieval mummy of religious significance, that of the Blessed Antonio Patrizi da Monticiano. A total of 79 puparia were examined and all were identified as Ophyra capensis (Diptera: Muscidae). Additionally, a desiccated moth (Lepidoptera: Tineidae) was encountered. Puparia of O. capensis would be associated with normal decomposition shortly after the death of the mummified individual, and not an infestation beginning during more recent years. Similarly, the tineid moth found would likely be related with decomposition of cloth associated with the remains. These findings illustrate how collection and identification of insects associated with human remains can distinguish between historical decomposition versus issues of modern curatorial concern.

    2009-04-01

    Stable fly (Diptera: Muscidae) populations in south central Ontario, Canada, first occur on dairy farms in late spring, grow exponentially throughout the summer, and are frozen back each autumn. We examined the extent of overwinter persistence on 22 dairy farms in a 55- by 60-km region north of Lake Ontario that spans four climatic zones. Our overwintering sampling of larval habitat identified three farms located in the southern section of the study region as potential overwintering refugia. Using sticky trap catches to identify the timing of first spring appearance at each farm, we then tested two models of how local farm populations are reestablished annually: 1) stable flies disperse from local climatic refuges and colonize neighboring farms (the local source model); and 2) stable flies are carried into the study region by frontal weather systems (the distant source model). The timing of when stable flies first occurred at these farms supported a local source of dispersing colonists from a small proportion of local refuge farms. We discuss our results in terms of how yearly fluctuation in climate would affect refuge farm density in the region and how this, in turn, would shift the recolonization dynamic. Implications for controlling stable flies also are discussed.

    California pastured cattle were treated with 250 ml of a 15% mixture of fatty acids (C8-C9-C10) or 125 ml of 2% geraniol in a mineral oil carrier to assess impacts on horn flies, Haematobia irritans (L.) (Diptera: Muscidae) over two summers. Horn flies were netted from cattle every 3-4 d for 2 wk before treatment, 2 wk during treatment (four treatments, with flies collected before each treatment), and 2 wk after treatments ceased. Blood meal weights were estimated by hemoglobin assay of excised abdomens. Other females were dissected to determine the number of active ovarioles and the stage of primary follicle development. Depending on year and herd, pretreatment males contained an average of 0.6-1.0 mg of blood, while females contained 1.7-2.7 mg. Pretreatment egg development (least developed oocytes were stage 1 and fully developed eggs were stage 5) averaged 3.7-4.3, and number of active ovarioles averaged 18.1 to 19.6/female. During treatment periods, significant reductions in blood weight were noted for females, but usually not for males, and females also often exhibited reduced mean oocyte stage and number of active ovarioles. Peaks in proportions of young nulliparous females (oocyte stages 1 or 2) were seen during some repellent application periods. This suggested older females had been killed or driven off from the local population by the treatments, and flies on cattle included more young flies that likely were recent arrivals. The repellent-oil mixture thus impacted blood feeding, reproductive fitness, and probably age structure in the field.

    Lambda-cyhalothrin, a sodium channel modulator insecticide, has been used frequently for the control of house flies, Musca domestica L. (Diptera: Muscidae) worldwide, including Pakistan. This experiment was performed to determine the selection and assessment of lambda-cyhalothrin resistance evolution along with four other insecticides. After 26 generations of selection, the lambda-cyhalothrin-selected population developed 445-fold resistance to lambda-cyhalothrin compared to the susceptible population. There was low cross-resistance to bifenthrin and very low cross-resistance to methomyl, imidacloprid, and fipronil in the lambda-cyhalothrin-selected population compared to the field population (G1). Realized heritability (h (2)) of resistance to lambda-cyhalothrin, bifenthrin, methomyl, imidacloprid, and fipronil was 0.07, 0.05, 0.01, 0.08, and 0.08, respectively. The projected rate of resistance development revealed that if 90 % house flies were selected, then a tenfold increase in lethal concentration 50 occurred after 17, 20, 159, 13, and 14 generations for lambda-cyhalothrin (h (2) = 0.07, slope = 2.09), bifenthrin (h (2) = 0.05, slope = 1.73), methomyl (h (2) = 0.01, slope = 2.52), imidacloprid (h (2) = 0.08, slope = 1.89), and fipronil (h (2) = 0.08, slope = 2.03), respectively. The results of our study concluded that the house fly has the potential to develop multiple insecticide resistances following continued selection pressure with lambda-cyhalothrin. This study will be helpful for assisting the development of resistance management strategies.

    Helina Robineau-Desvoidy, 1830 is the second genus of Muscidae in terms of richness. This genus includes several species collected at high altitudes and high latitudes, and is poorly studied in the Neotropical region. Only 12 species of Helina have been recorded in the southern limit of South America in the Andean-Patagonian forests. In the present work, we studied all the species known from the Andean-Patagonian forests, with the exception of H. viola Malloch, 1934, present three new species, H. araucana sp. nov., H. dorada sp. nov., and H. ouina sp. nov., and provide the first description of the females of H. australis Carvalho & Pont, 1993 and H. rufoapicata Malloch, 1934. We also propose four new synonymies: H. nigrimana basilaris (Carvalho & Pont, 1993) and H. nigrimana grisea (Malloch, 1934) as new junior synonyms of H. nigrimana (Macquart, 1851); and H. fulvocalyptrata Malloch, 1934 and H. simplex Malloch, 1934 as new junior synonyms of H. chilensis Malloch, 1934. Finally, we provide a generic diagnosis and a new key for the Helina species of the Andean-Patagonian forests, as well as notes on the biology and distribution maps of each specimen, and discuss a preliminary contruction of groups of species.

    Full Text Available Foregut in D. hominis (Linnaeus Jr., 1781 as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the foregut. Metamoiphosis begins at the end of the larval period with signs of nuclear degeneration of all the polytenic cells, as well as the increase in number of the imaginal disk ones. The oesophagic portion intussuscepted into the cardia, everts; its cells suffer apoptosis and are replaced by the new cells growing from the imaginal disk. The external layer cells also degenerate and are pinched off into the lumen of the very anterior portion of the midgut. The newly formed oesophagus intussuscepts "de novo" to form the two internal layers of the adult cardia. At the same time the midgut regenerative cells grow anteriorly to form the new external layer of the adult cardia.

    The Muscidae is one of the main dipteran families recognized as important for medico-legal purposes. Although an association of adult flies with decomposing human and animal bodies is documented for about 200 taxa worldwide, cadavers and carrion represents a breeding habitat for considerably fewer species. Species that do colonize dead human bodies can do so under diverse environmental conditions and, under certain circumstances, Muscidae may be the only colonizers of a body. Because of difficulties in identification, many studies have identified immature and/or adult muscids only to the genus or family level. This lack of detailed species-level identifications hinders detailed investigation of their medico-legal usefulness in carrion succession-oriented experiments. Identification to species level of third instars of Muscidae of forensic importance and the utility of larval morphological characters for taxonomic purposes were subjected to an in-depth revision. A combination of characters allowing for the discrimination of third instar muscids from other forensically important dipterans is proposed. An identification key for third instar larvae, which covers the full set of cadaver-colonising species of Muscidae from the western Palaearctic (Europe, North Africa, Middle East), is provided. This key will facilitate more detailed and species-specific knowledge of the occurrence of Muscidae in forensic entomology experiments and real cases. The carrion-visiting Muscidae worldwide are catalogued, and those species breeding in animal carrion and dead human bodies are briefly discussed with regard to their forensic importance.

The gamma radiation source used was a Cobalt-60 irradiator, Gamma bean-650, with an initial activity of 1,6265 x 10 4 Bq (6,746 Ci). The radiation LD 50 e LD 100 , using a dose ratio of 1457 Gy/h, for 12, 24, 36, 48, 60 and 72 hours old pupae and resulted in 15.35; 15.69; 11.30; 49.4; 142.78 and 175 Gy for LD 50 and 20, 22.5; 32.5; 175; 225 and 300 Gy for LD'1 00 respectively. Following exposure, the pupae were kept in climate chamber at 27 ± 3 0 C and 75 ± % of relative humidity, until all adults had emerged. In succession, 24, 48 and 72 hour-old pupae were exposed to gamma irradiation with a dose of 1440 Gy/hour, in their respective lethal doses. Following the exposure the pupae were stored at cool temperature (10 ± 2 0 C) for different periods of time (5, 15, 20 and 30 days). The same treatment was given for non-irradiated pupae. After the storage period the pupae were expose for 24 h to S. endius in a ratio of 1:10 parasitoid-host. It was not observed any statistical difference (Turkey 5%) in progeny of males and females emerged from irradiated and non-irradiated pupae. There was a preference of the parasitoid to pupae of 48 hours old followed by 24 and 72 hours old for storage period more than 5 days and shorter than 20 days. (author). 50 refs., 6 figs., 17 tabs

    Full Text Available Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i carcasses with larger biomass developed a higher abundance of flies and (ii the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819. (iv An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.

    Full Text Available The digestive tube of 2nd and 3rd instar larvae, pupae and newly emerged adults of Dermatobia hominis (Linnaeus, 1781 was studied anatomically. The specimens were dissected in buffer saline under a stereomicroscope, and the digestive tubes were placed on slides and fixed in 10% buffered formalin. Each tube was measured using a micrometric eye piece, and drawings were made with camera lucida. The results showed that the midgut, the hindgut and the Malpighian tubules with their ducts grow gradually during the larval development. The oesophagus and the salivary glands with their ducts grow only during the moult from the 2nd to the 3rd instar. In the pupal period, salivary glands grow gradually but disappeared after the 20th day. After metamorphosis the digestive tube regressed. This is expected since adult D. hominis lives about nine days without feeding. This fly, similar to other calyptratae muscoid flies shows no vestige of a crop during all post-embrionic development, and the adult has no salivary glands.

To the local known species some Muscidae were increased as follows: Neomuscina atincticosta, Pseudoptilolepis elbida, Polietina orbitalis, Polietina flavithorax, Scutellomusca scutellaris, Graphomya analis and Morellia couriae.As moscas sinantrópicas se destacam pelo fato de serem relativamente abundantes junto à população humana e animais domésticos, podendo causar a estes miíases ou transmitir agentes patogênicos. Por serem necrófagas, atuam na decomposição de cadáveres e são úteis para a entomologia forense como indicadores na determinação do intervalo post mortem - IPM. Este trabalho visou conhecer a diversidade e a abundância das espécies em Campo Grande, Estado de Mato Grosso do Sul. As capturas foram realizadas semanalmente, com três armadilhas, utilizando isca de peixe deteriorado, durante o período de junho de 2008 a maio de 2009 em mata ciliar remanescente na fazenda experimental da Embrapa Gado de Corte. Foram consideradas as seguintes famílias de dípteros, seguidas pelo número de exemplares obtidos: Calliphoridae (105.334; Muscidae (27.999; Sarcophagidae (21

    Full Text Available O primeiro registro de dípteros das famílias Muscidae, Sarcophagidae, Calliphoridae e Mesembrinellidae da Estação Biológica de Santa Lúcia (EBSL é apresentado e discutido, baseado em coletas realizadas no ano de 2007. Os exemplares foram capturados com o auxílio de armadilha adaptada de modelo proposto para lepidópteros, utilizando sardinha como isca e Malaise, além de coleta ativa com rede entomológica. Como resultado foram obtidos 1.253 espécimes, com destaque para as famílias Calliphoridae, Muscidae, Sarcophagidae e Mesembrinellidae. É discutida a dualidade gerada pela presença de espécies com baixo grau de sinantropia e outras altamente sinantrópicas, caracterizando a área de coleta como uma região de transição entre áreas rural e florestal. A observação de espécies sinantrópicas está provavelmente correlacionada ao efeito de borda. Os resultados evidenciam a importância da criação de uma zona de amortecimento no entorno da EBSL com intuito de minimizar os impactos gerados às espécies nativas.

    Full Text Available A cladistic analysis for 27 muscid genera is given, running the PAUP program (SWOFFORD, 1985. The 35 characters used in this study are polarized based on three outgroups of related families. A cladogram showing hypothetical phylogenetic relationships among genera and a discussion of the characters enable to propose a sequencial phylogenetic classification of Muscidae at tribal level. The following seven subfamilies and eight tribes are included: Achanthipterinae; Atherigoninae; Muscinae, with Muscini and Stomoxiini; Azeliinae, with Azeliini and Reinwardtiini; Phaoniinae; Mydaeinae, with Graphomyiini and Mydaeini and Coenosiinae, with Coenosiini and Limnophorini. Helina Robineau-Desvoidy, 1830 has not a defined position in the obtained cladogram to the considered levels. The neotropical species of Phaonia (aut. must be separated in a new genus. The proposed classification is compared with contemporaneous classifications. The greatest congruence is found with that of SKIDMORE (1985.

    In an initial observation, large numbers of muscoid flies (Diptera) were captured as nontarget insects in traps baited with solutions of acetic acid plus ethanol. In subsequent field experiments, numbers of false stable fly Muscina stabulans (Fallén) and little house fly Fannia canicularis (L.) trapped with the combination of acetic acid plus ethanol were significantly higher than those trapped with either chemical alone, or in unbaited traps. Flies were trapped with acetic acid and ethanol that had been formulated in the water of the drowning solution of the trap, or dispensed from polypropylene vials with holes in the vial lids for diffusion of evaporated chemical. Numbers of both species of fly captured were greater with acetic acid and ethanol in glass McPhail traps, compared to four other similar wet trap designs. This combination of chemicals may be useful as an inexpensive and not unpleasant lure for monitoring or removing these two pest fly species.

    Full Text Available Dermatobia hominis (Linnaeus, 1781 midgut is internally lined by an epithelium of polytenic cells, some low others prismatic with well developed brush border. Their apical portion are enlarged by secretory vesicles, forming button-like structures that are pinched off to the lumen, some accompained by the nucleus characterizing apocrine and holocrine secretions. This epithelium is gradually renewed by small, non polytenic regenerative cells, found scattered at its basal portion. At the end of the third instar the metamorphosis begins. The epithelial cells present signs of degeneration and at the first day of pupation the regenerative cells increase in number. By the 5th day of pupation these regenerative cells, besides being increased in number, differentiate themselves into two layers: one similar to the dense conective tissue that sustainning the larval epithelium is pinched off to the midgut lumen forming the "yellow bodies"; the other, develops right under it as the imaginal epitelium. The disorganized muscles bundles of the midgut wall, are invaded by phagocytes. At the end of pupation the midgut has a low prismatic epithelium with brush-border. In the adult, the torax portion of the midgut has prismatic homogeneously basophilic epithelium while in the abdominal portion the epithelium is made of high prismatic cells full of small vacuoles. The larval midgut epithelium suffers programmed cell death non compatible with apoptose. During the metamorphosis the midgut lenght diminishes from 31mm in the larva to 14mm in the adult.

Usually, controls of these vectors are done using chemical insecticides. Research on mosquito resistance has been done, but the impact of mosquitoes that survive after synthetic (chemical insecticides application has not been studied. The aim of this research was to analyze the differences of fecundity, fertility and vitality rate of mosquitoes that were exposed to natural insecticides i.e with burned breadnut flowers and mosquito coils containing transflutrin and d-aletrin. Mosquito samples were taken from field eggs which were exposed with synthetic and natural insecticides. Mosquitoes that remainder alive after 24 hours exposure were mated and each group were put in 2 cages, each repetition were repeated 3 times. The mosquito eggs were observed until adult mosquitoes die. Then, the fecundity, fertility and vitality rate were compared. Based on our analysis, there were no differences on fecundity rate, between control and mosquitoes that were exposed to natural insecticides, but there were significant differences between the control and the synthetic insecticides. Natural insecticides do not increase the rate of fecundity but synthetic insecticides may increase the rate of fecundity and number of mosquitoes and causes the mosquito lifespan longer than the control and natural insecticide treatment.

    Full Text Available INTRODUCTION: The need for studies that describe the resistance patterns in populations of Aedes aegypti (Linnaeus in function of their region of origin justified this research, which aimed to characterize the resistance to temephos and to obtain information on esterase activity in populations of Aedes aegypti collected in municipalities of the State of Paraíba. METHODS: Resistance to temephos was evaluated and characterized from the diagnostic dose of 0.352mg i.a./L and multiple concentrations that caused mortalities between 5% and 99%. Electrophoresis of isoenzymes was used to verify the patterns of esterase activity among populations of the vector. RESULTS: All populations of Aedes aegypti were resistant to temephos, presenting a resistance rate (RR greater than 20. The greatest lethal dose 50% of the sample (CL50 was found for the municipality of Lagoa Seca, approximately forty-one times the value of CL50 for the Rockefeller population. The populations characterized as resistant showed two to six regions of α and β-esterase, called EST-1 to EST-6, while the susceptible population was only seen in one region of activity. CONCLUSIONS: Aedes aegypti is widely distributed and shows a high degree of resistance to temephos in all municipalities studied. In all cases, esterases are involved in the metabolism and, consequently, in the resistance to temephos.

Apresentam-se os dados da influência de diferentes períodos de quiescência sobre a eclosão das larvas, desenvolvimento larval e pupal, ciclo evolutivo. Verificou-se o efeito altamente significativo do período de quiescência na eclosão das larvas. O período de quiescência não influenciou nas durações dos períodos de incubação, larval e pupal. Constatou-se que ovos de um mesmo período de quiescência apresentaram períodos de incubação estatisticamente diferentes entre si. As larvas eclodiam em grupos, definidos pela incubação, e este efeito de grupo foi significativo na duração do ciclo. Pode-se afirmar que, em 99,8% dos ciclos, a variação foi determinada pela incubação.

    Dengue is considered a serious public health problem in many tropical regions of the world including Brazil. At the moment, there is no viable alternative to reduce dengue infections other than controlling the insect vector, Aedes aegypti Linnaeus. In the continuing search for new sources of chemicals targeted at vector control, natural products are a promising alternative to synthetic pesticides. In our work, we investigated the toxicity of a bioactive compound extracted from the red alga Laurencia dendroidea J. Agardh. The initial results demonstrated that crude extracts, at a concentration of 5 ppm, caused pronounced mortality of second instar A. aegypti larvae. Two molecules, identified as (−)-elatol and (+)-obtusol were subsequently isolated from crude extract and further evaluated. Assays with (−)-elatol showed moderate larvicidal activity, whereas (+)-obtusol presented higher toxic activity than (−)-elatol, with a LC50 value of 3.5 ppm. Histological analysis of the larvae exposed to (+)-obtusol revealed damage to the intestinal epithelium. Moreover, (+)-obtusol-treated larvae incubated with 2 µM CM-H2DCFDA showed the presence of reactive oxygen species, leading us to suggest that epithelial damage might be related to redox imbalance. These results demonstrate the potential of (+)-obtusol as a larvicide for use against A. aegypti and the possible mode of action of this compound. PMID:26821032

    Full Text Available Larvae of Hermetia illucens fly (Linnaeus is an important source of alternative protein and can be used as pellets for feeds. Currently the production of H. illucens larvae is still limited because its rearing depends on palm kernel meal. The objective of the research is to explore alternative media for rearing, i.e. using loading ramp waste from crude palm oil factory. The study was conducted using physical-chemical analysis of the media. Evaluation of potential rearing media of loading ramp was done by studying the suitability of loading ramp fermented by EM4®, rumen microbes, and organic liquid fertilizer and without fermentation. Treatment media was develop with an enrichment ratio of 1 : 0.25, 1 : 05, and 1 : 1 (v/v for bran and husk, and 1.25, 2.5, and 5% (w/w for coconut sugar. Each experiment was arranged in complete randomized design using 20 larva of the 2nd instar. Larvas were incubated in plastic with tube with diameter of 10 cm and 20 cm in height containing of media 300 g. Response differences in growth and mortality were analyzed by ANOVA and least significant differences test at 0.05 levels. Preference and analysis suitability of the media were conducted using material enrichment. Results show that the loading ramp waste contain 9.80% protein and 10.32% fat. Although the media are could support growth and development of the larvae at different degree, media from waste fermentation POC loading ramp with bran enrichment 1 : 0.5 (v/v is the best media for rearing larva.

    Full Text Available The effects of eucalyptol were evaluated against the house fly, Musca domestica L., and blow fly, Chrysomya megacephala (F.. The bioassay of adults, using topical application, indicated that M. domestica males were more susceptible than females, with the LD50 being 118 and 177 mg/fly, respectively. A higher LD50 of C. megacephala was obtained; 197 mg/fly for males and 221 mg/fly for females. Living flies of both species yielded a shorter life span after being treated with eucalyptol. The bioassay of larvae, using the dipping method on the third instar, showed that M. domestica was more susceptible than C. megacephala, with their LC50 being 101 and 642 mg/ml, respectively. The emergence of adults, which had been treated with eucalyptol in larvae, decreased only in M. domestica. Having the volatile property, fumigation or impregnated paper test of eucalyptol or the efficacy of repellence or attractiveness merits further investigations to enhance bio-insecticidal efficacy.

    Full Text Available Fly puparia and adult fragments of diptera muscid were found inside the esophagus of a mummified body from the early XIX century, buried inside the crypt of the Sacrament Church (Lisbon, Portugal. The identification of the material revealed a monospecific colonization by Ophyra capensis (Wiedemann (Diptera: Muscidae, a species known to invade corpses in the ammoniacal fermentation wave. This species can be found in corpses kept indoors, not available to the early waves of blowflies (Diptera: Calliphoridae. In the present case, the number of pupae and their developmental stage suggest that the female invaded the mummified corpse through the partially opened mouth and the oviposition took place directly inside the esophagus. This is the first case of O. capensis infesting internal organs of an intact corpse. The use of chemical products for the embalming process probably explains why external colonization did not occur.

    Full Text Available The present paper discusses the importance of analysing the frequency of flies of the Muscidae and Calliphoridae family, evaluating the impact of the implementation of urban garbage collection’s programs. It was examined the case study of the city Tupa – Sao Paulo’s State- which was divided in two distinct phases: phase 1 – between June and October of 2001, characterized by the presence of landfill and; phase 2 – from November of 2001 to May of 2002, characterized by the beginning of the implementation of selective collection and recycling and gradual dump grouding. The procedure for the capture of the insects was made with ten traps made with two-liter plastics bottles placed in houses and trees around the landfill. As an attractive, 400 mL of spill from sugar cane was used and replaced weekly. In both phases of the research was observed that the most frequent and constant family was the Calliphoridae. There was a positive correlation before the selective collection between the number of Calliphoridae and the rainfall (0,638 and the number of muscideos and the average temperature (0,605. After the collection program started, this correlation was not observed any more. To conclude, the program of selective collection implanted in the city of Tupa resulted in a decrease in the frequency of diptera. The analysis of the Callidoridae and Muscidae float demonstrated to be an efficient indicator of the environmental quality.

    Most reports published in the field of forensic entomology are focused on Diptera and neglect the Hymenoptera community. However, Hymenoptera are part of the entomofaunal colonization of a dead body. The use of Hymenoptera parasitoids in forensic entomology can be relevant to evaluate the time of death. Hymenoptera parasitoids of the larvae and pupae of flies may play an important role in the estimation of the post-mortem period because their time of attack is often restricted to a small, well-defined window of time in the development of the host insect. However, these parasitoids can interfere with the developmental times of colonizing Diptera, and therefore a better understanding of their ecology is needed. The work reported here monitored the presence of adult Hymenoptera parasitoids on decaying pig carcasses in an urban biotope during the summer season (from May to September). Six families and six species of parasitoids were recorded in the field: Aspilota fuscicornis Haliday (Braconidae), Alysia manducator Panzer, Nasonia vitripennis Walker (Pteromalidae), Tachinaephagus zealandicus Ashmead (Encyrtidae), Trichopria sp. (Diapriidae), and Figites sp. (Figitidae). In the laboratory, five species emerged from pupae collected in the field: Trichopria sp., Figites sp., A. manducator, N. vitripennis, and T. zealandicus. These five species colonize a broad spectrum of Diptera hosts, including those species associated with decomposing carcasses, namely those from the families Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae.

    The diversity of necrophagous Diptera is largely unknown in seasonally dry tropical forests, despite their medical, veterinary, and forensic relevance. We performed a study in the dry Caatinga forest exclusive to Brazil in order to assess the diversity and temporal pattern of Diptera species using pig carcasses as substrates. Adults were collected daily until complete skeletonization. We collected 17,142 adults from 18 families, 10 of which comprise species with known necrophagous habits. The most abundant families were Calliphoridae (47.3% of specimens), Sarcophagidae (20.8%), and Muscidae (15.5%), whereas Sarcophagidae stood out in terms of richness with 21 species. The native Cochliomyia macellaria (F.) (Diptera: Calliphoridae) and the invasive Chrysomya albiceps (Wiedmann) (Calliphoridae) were the dominant species. A total of 18 species reached the carcass during the first 48 h postdeath. The bloated and active decay stages had the highest richness and abundance of dipterans. From a forensic standpoint, C. macellaria and C. albiceps are likely to aid in establishing postmortem interval due to their early arrival and high abundance on the carcass. Despite harsh environmental conditions, the Caatinga harbors a rich assemblage of dipterans that play a key role in carrion decomposition. Their medico-veterinary importance is strengthened by the poor local sanitary conditions. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

    Full Text Available From June 1993 to May 1995, horn fly counts were conducted twice a month on untreated Nelore cattle raised extensively in the Pantanal. Horn fly population showed a bimodal fluctuation and peaks were observed every year after the beginning (November/December and at the end (May/June of the rainy season, which coincided with mid-late spring and mid-late fall, respectively. Horn flies were present on cattle throughout the year in at least 64% of the animals. Mean horn fly numbers on animals did not exceed 85 flies/cow during peaks and were under 35 flies/cow in most of the remaining periods. The highest infestations (population peaks were short and dropped suddenly within two weeks. Less than 15% of the animals in both herds could be considered as "fly-susceptible" - showing consistently higher infestations, or "fly-resistant" - showing consistently lower infestations.

    Full Text Available Introduction. Flies – by feeding on decaying matter, human waste and food – have been implicated in the spread of numerous animal and human diseases. Excessive fly populations are generally associated with livestock units and domestic waste due to decaying organic matter. A large number of flies cause extreme disturbance in the behavior of the host, resulting in skin irritation, lesions, wounds, and secondary infections are likely to appear. Objective. The aim of this study was to evaluate the effects of combined applications of larvicide (cyromazine and adulticides (acetamiprid in formulation with pheromone and thiamethoxam on the suppression of fly populations. Materials and methods. The study was conducted on a pig farm. The piglet farms are one of the most favorable places for fly breeding. Three units were used for biocide applications and a fourth unit as the control where biocides were not applied. The monitoring of pre- and post-treatment of adult fly populations was carried out by glued cardboards. The cards were hung on metal rods above piglet’s cage. This monitoring method served as a parameter for the estimation of biological effectiveness. Results. The highest degree of fly control (88.4% mortality 8 days after treatment was achieved when a combination of cyromazine and thiamethoxam was used. A biocide based on sex pheromone (Z-9-tricosene + acetamiprid was the most effective on flies 3 days after biocide application, with a mortality rate of 69.1 %. Thiamethoxam achieved the highest reduction of flies 6 days after treatment, with 78.19% obtained mortality. Conclusion. Biological efficacy of the applied biocides in combination ciromazine + thiamethoxam and thiamethoxam alone was justified.

    Pupae of the face fly were irradiated at 5 days of age using gamma radiation from a Co-60 source. Experiments were conducted to determine the effect of radiation dose on the fertility and longevity of the resulting adults. An irradiation dose of 2.5 krad induced permanent sterility in both males and females without affecting their longevity significantly. Competitive and mating tests indicated that males irradiated at 2.5 krad were as competitive as normal males. A colony of flies was infected with the nematode parasite, Heterotylenchus autumnalis Nickle. Irradiation of parasitized, 5-day-old pupae, indicated that the parasite was not adversely affected by radiation doses of 1.0 and 2.5 krad. (author)

Complete information is given for each type, including reference to the original description, label data, and preservation condition. 

  12. Bad math in Linnaeus' Philosophia Botanica.

    Podani, János; Szilágyi, András

    2016-09-01

    In Philosophia Botanica (1751), Carolus Linnaeus (1707-1778) presented a calculation of the number of plant genera that may be distinguished based on his taxonomic concepts. In order to derive that number, he relied upon the organs of fructification, which represent the flower and the fruit, by selecting over 30 elements from them, and then assuming that each could vary by four dimensions. However, while Linnaeus was good in counting stamens and pistils, he and many of his followers who edited or translated Philosophia Botanica were less careful, basing their calculations of the number of possible genera on flawed assumptions, or even introducing basic arithmetic errors. Furthermore, although mathematics was quite advanced in the eighteenth century, the gap between combinatorial and botanical thinking was too deep, preventing Linnaeus to seek a reasonable solution to the problem he raised. The authors demonstrate this by a historical analysis of 15 editions of Philosophia Botanica, plus many references to it, and conclude that the desired number almost always appeared in error during the past 265 years. The German botanist J. G. Gleditsch (1714-1786) was the most successful with respect to Linnaeus' original intention. Elementary mathematics demonstrates that if Linnaeus' assumptions were taken seriously, then the possible number of genera would be astronomical. The practice he followed in Genera Plantarum (1754) shows, however, that the fructification dimensions served as a universal set for Linnaeus from which he chose only the relevant ones for describing a particular genus empirically. Based on the corrections and modifications implemented in reworked editions, we suggest an evolutionary network for the historical and modern versions or translations of Philosophia Botanica.

    Precise species identification of every insect sample collected from criminal scenes play an essential role in the accurate estimation of postmortem interval. The morphological similarity poses a great challenge for forensic entomologists. DNA-based method can be used as a supplemental means of morphological method. In the present study, we demonstrate the applicability of the 304-bp cytochrome oxidase I gene fragment in molecular identification of forensically important Diptera. We analyzed 75 specimens belonging to 19 species of 3 families originating from China (Calliphoridae: Chrysomya megacephala, Chrysomya albiceps, Chrysomya rufifacies, Chrysomya nigripes, Aldrichina grahami; Lucilia bazini, Lucilia caesar, Lucilia cuprina, Lucilia sericata, Lucilia porphyrina; Muscidae: Musca autumnalis, Musca domestica, Fannia canicularis, Stomoxys calcitrans; Sarcophagidae: Sarcophaga albiceps, Sarcophaga dux, Helicophagella melanura) and Egypt (Calliphoridae: C. megacephala, C. albiceps, L. sericata; Muscidae: M. domestica, F. canicularis, S. calcitrans, Synthesiomyia nudiseta; Sarcophagidae: Sarcophaga argyrostoma). This region was amplified using polymerase chain reaction followed by direct sequencing of the amplification products. Nucleotide sequence divergences were calculated using the Kimura two-parameter distance model and a neighbor-joining phylogenetic tree generated. Intraspecific variation ranged from 0-0.8 % and interspecific variation occurred between 1-19 %. Although all examined specimens were assigned to the correct species and formed distinct monophyletic clades, the data of the phylogenetic analysis were not completely in accordance with the traditional morphological classification. As both C. nigripes and A. grahami unexpectedly joined with Muscidae and Sarcophagidae groups respectively. Moreover, both Calliphorinae and Luciliinae clades failed to represent Calliphoridae as a separate group. Therefore, although molecular methods are beneficial

    PETER LOWENBERG-NETO

    2012-09-01

    Full Text Available In a study on Fanniidae biogeography, Dominguez & Roig-Juñent (2011 argued that the family had a Pangeic origin, Late Jurassic/early Cretaceous (~146 Ma. However, recent literature on Diptera supports that Schizophora radiation occurred during Cenozoic. Fanniidae is a widespread taxon and it was interpreted under the maximum vicariance paradigm; the consequence was an analysis with no alternative hypothesis, but Pangeic origin. We verified that Fanniidae historical narrative was incongruent with the Gondwana sequential break-up. A second analysis, assuming the Fanniidae origin during early Paleocene (65 Ma, showed congruence with recent geological events and with the Muscidae diversification, a closely related Muscoidea family. Our hypothesis suggests that the Fanniidae originated in Paleogene and they were affected by few events of vicariance and several expansions during Cenozoic.En un estudio sobre biogeografía de Fanniidae, Domínguez & Roig-Juñent (2011 argumentaron que la familia era de origen Pangeico, Jurásico superior/Cretáceo inferior (~146 Ma. Sin embargo, literatura reciente sobre Diptera, confirma que la radiación de Schizophora ocurrió durante el Cenozoico. Fanniidae es un taxón ampliamente distribuido y fue interpretado bajo el paradigma de máxima vicarianza; la consecuencia, fue un análisis sin hipótesis alternativas, pero de origen pangeico. Nosotros verificamos que la narrativa histórica de Fanniidae es incongruente con la quiebra secuencial de Gondwana. Un segundo análisis, asumiendo el origen de Fanniidae durante el Paleoceno inferior (65 Ma, mostró congruencia con eventos geológicos recientes y con la diversificación de Muscidae, una familia de Muscoidea próximamente relacionada. Nuestra hipótesis sugiere que Fanniidae se originó en el Paleógeno y fueron afectados por pocos eventos de vicarianza y muchas expansiones durante el Cenozoico.

    Insects associated with carrion can have parasitological importance as vectors of several pathogens and causal agents of myiasis to men and to domestic and wild animals. We tested the attractiveness of animal baits (chicken liver) at different stages of decomposition to necrophagous species of Diptera (Calliphoridae, Fanniidae, Muscidae, Phoridae and Sarcophagidae) in a rainforest fragment in Brazil. Five types of bait were used: fresh and decomposed at room temperature (26 °C) for 24, 48, 72 and 96 h. A positive correlation was detected between the time of decomposition and the abundance of Calliphoridae and Muscidae, whilst the abundance of adults of Phoridae decreased with the time of decomposition. Ten species of calliphorids were registered, of which Chrysomya albiceps, Chrysomya megacephala and Chloroprocta idioidea showed a positive significant correlation between abundance and decomposition. Specimens of Sarcophagidae and Fanniidae did not discriminate between fresh and highly decomposed baits. A strong female bias was registered for all species of Calliphoridae irrespective of the type of bait. The results reinforce the feasibility of using animal tissues as attractants to a wide diversity of dipterans of medical, parasitological and forensic importance in short-term surveys, especially using baits at intermediate stages of decomposition.

    Full Text Available Inventories on necrophagous insects carried out in Brazil encompass mostly species from the southeastern and central-western regions of the country. This review aims to produce the first checklist of necrophagous Diptera and Coleoptera species of forensic relevance in northeastern Brazil, an area that concentrates high rates of homicides. We performed a literature survey on scientific articles, theses and dissertations regarding necrophagous insect species in the region, and contacted scientists who develop research on forensic entomology. Fifty-two species of Diptera belonging to eight families with previous record of necrophagy were reported in the region: Sarcophagidae, Calliphoridae, Muscidae, Fanniidae, Piophilidae, Phoridae, Anthomyiidae and Stratiomyidae. Coleopteran species from six families of forensic relevance were registered, although taxonomical identification remained superficial. Bait traps were the most frequent methodology used, followed by collection on animal carcasses. Seven Dipteran species from two families were registered on human cadavers. All species had been previously reported in other Brazilian states and/or other countries, although none has been effectively used in legal procedures in the region. The status of research on forensic entomology in northeastern Brazil is incipient, and the checklist produced here contributes to the knowledge on the local diversity of necrophagous insects.

    Full Text Available Aspects related to the longevity and oviposition of Ophyra albuquerquei Lopes, 1985 are studied. Males had a mean lifespan longer than females (40.24 vs. 33.15 days, respectively, while still possessing qualitative advantages during this period. Females O. albuquerquei were fed on powdered milk, fish flour, refined sugar and water, and provided fish flour and moistened sawdust for oviposition. The length of the oviposition period for females was 46.75 days, and most of the deposition of the eggs occurred in the first days of the colony. Females completed 50% of their egg deposition by Day 16, seven days before the large last mortality peak and about 12 days after the first oviposition in the colony. Females deposited an average of 184 eggs per individual. Mortality of males, unlike females, was low until the 28th day, and increased thereafter. It was demonstrated that it is possible to maintain colonies of this species under laboratory conditions for at least 28 days with high fertility and low cost.

    The interaction between gamma irradiation and nutrition in the house fly, M. domestica, was investigated following irradiation of 2-hr-old adult virgin females mated with non-irradiated males. Radiation levels used were: 0 (non-irradiated), 250 rads, 500 rads, 750 rads, and 1,500 rads. Flies were fed diets consisting of varying ratio by weight of casein and sucrose at 1:1, 0.5:1, 1:0.5, and 0.1 respectively, and kept in the insectary at 25 +- 2 0 C and 70 percent R.H. Egg hatchability, adult emergence, body and ovary weights, survival of irradiated females, and histopathology were investigated at 4, 7, 11, and 15 days after irradiation. Survival of irradiated females was also determined at 45 days after irradiation. The results of these studies suggest that carbohydrate is important in house fly survival and repair of radiation damage

    Beauveria bassiana plays a prominent role in biocontrol of houseflies, Musca domestica (L.). Thus, a deeper insight into immune response of M. domestica during B. bassiana infection was warranted to assist the production of more efficient mycoinsecticides. The present study investigates changes in protein profile of M. domestica hemolymph serum post B. bassiana infection using two-dimensional difference gel electrophoresis (2D-DIGE) followed by identification of selected proteins by matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS). The non-infected or control group of flies showed an expression of 54 proteins, while M. domestica infected with B. bassiana expressed a total of 68 hemolymph serum proteins. Thirty three proteins were expressed in both groups of houseflies, whereas 35 proteins were exclusively expressed in infected flies and 21 proteins were exclusively expressed in control flies. Among the 33 proteins which were expressed in both groups of houseflies, 17 proteins showed downregulation, while16 proteins were upregulated in the infected flies compared to the non-infected ones. The results from this study are expected to facilitate better understanding of insect's immune response mechanism.

    2017-01-01

    The horn fly, Haematobia irritans (L.) is an important cattle pest and traditionally has been managed using insecticides; however, many horn fly populations are insecticide-resistant in United States. Use of alternative control techniques has been limited because of the challenges of managing a fly pest on pastured cattle. After the discovery of a wild horn fly infected with Beauveria bassiana in Florida, the fungus was cultured and evaluated for efficacy against laboratory-reared horn flies. This fungal strain was selected for increased virulence by passage through laboratory-reared horn fly hosts to shorten interval from infection to fly death and subsequent conidia formation, properties important to future use of the fungus as a biological control agent against horn flies. After seven passages through horn fly hosts, fly mortality was not significantly accelerated as evaluated through LT50 values, but conidia were readily produced from these killed flies. Although further development is needed to improve fungal efficacy, this fungal strain holds promise as a biological control agent for inclusion in horn fly integrated pest management programs.

    Hogsette, Jerome A; Foil, Lane D

    2018-04-02

    Stable fly management is challenging because of the fly's dispersal behavior and its tendency to remain on the host only while feeding. Optically attractive traps have been used to survey and sometimes reduce adult populations. Insecticide-treated blue and black cloth targets developed for tsetse fly management in Africa were found to be attractive to stable flies in the United States, and various evaluations were conducted in Louisiana and Florida. Tests using untreated targets were designed to answer questions about configuration, size, and color relative to efficacy and stability in high winds. Studies with electric grid targets and with targets paired with Olson traps showed cloth target color attraction in the following decreasing order: black > blue-black > blue. A solid black target is easier to make than a blue-black target because no sewing is involved. Attraction was not affected when flat 1-m2 targets were formed into cylinders, despite the limited view of the blue and black colors together. There was no reduction in attraction when the 1-m2 cylindrical targets were compared with smaller (63 × 30 cm high) cylindrical targets. In addition, there was no difference in attraction between the small blue-black, blue, and black targets. Significance of findings and implications of potential uses for treated targets are discussed. Target attraction was indicated by the numbers of stable flies captured on an Olson sticky trap placed 30 cm from the target. Although this system is adequate for field research, it greatly underestimates the actual numbers of stable flies attracted to treated targets.

    Musca domestica is one of the most important pests of human health, and has developed strong resistance to many chemicals used for its control. One important approach for creating new pesticides is the exploration of novel compounds from plants. During a wide screening of plants with insecticidal properties that grow in southern China, we found that the methanolic extracts of Myrsine stolonifera had insecticidal activity against the adults of M. domestica. However, the insecticidal constituents and mechanisms of the M. stolonifera extracts remain unclear. The insecticidal components of the methanolic extracts of M. stolonifera were isolated with activity-guided fractionation. From the spectra of nuclear magnetic resonance (NMR) and mass spectrometry (MS), the compounds were identified as syringing (1), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-d-glu (2), kaempferol-3-O-glu-rha-glu (3), and quercetin-3-O-glu-rha-glu (4). This study is the first to report the spectral data for compounds 3 and 4, and their LC 50 values were 0.52mg/g sugar and 0.36mg/g sugar 24h after treatment of the adults of M. domestica, respectively. Compounds 3 and 4 (LC 25 ) also inhibited the activities of the enzymes carboxylesterase, glutathione S-transferase, mixed function oxidase, and acetylcholine esterase of adult M. domestica, particularly mixed function oxidase and acetylcholine esterase. The cytotoxic effects of compounds 3 and 4 on cell proliferation, mitochondrial membrane potentials (MMP) and reactive oxygen species (ROS) were demonstrated on SL-1 cells. From the extracts of M. stolonifera, quercetin-3-O-glu-rha-glu and kaempferol-3-O-glu-rha-glu have displayed comparable toxicities to rotenone on M. domestica and also exhibited cytotoxic effects on SL-1 cells; therefore, the extracts of M. stolonifera and their compounds have potential as botanical insecticides to control M. domestica.

    House flies are one of the major public health pests in urban settings. People usually use insecticides containing pyrethroids for the management of house flies; however, there is a lack of information on pyrethroid resistance in house flies from urban areas. In the present study, resistance to four pyrethroids (beta-cyfluthrin, deltamethrin, permethrin, transfluthrin) was assessed in house flies collected from urban areas of Punjab, Pakistan. Significant levels of resistance to all the pyrethroids were found in different strains of house flies. The resistance ratios (RRs) at the median lethal dose (LD 50 ) level were in the range of 5.25- to 11.02-fold for beta-cyfluthrin, 7.22- to 19.31-fold for deltamethrin, 5.36- to 16.04-fold for permethrin, and 9.05- to 35.50-fold for transfluthrin. Pairwise comparison of the log LD 50 s revealed a highly significant correlation (p house flies from urban areas of Punjab. Regular resistance monitoring surveys and integrated approaches for the management of house flies are needed to retain the efficacy of these insecticides for a longer period of time.

    Pineapple production in Costa Rica increased nearly 300-fold during the last 30 yr, and >40,000 hectares of land are currently dedicated to this crop. At the end of the pineapple cropping cycle, plants are chopped and residues incorporated into the soil in preparation for replanting. Associated with increased pineapple production has been a large increase in stable fly, Stomoxys calcitrans (L.), populations. Stable flies are attracted to, and oviposit in, the decomposing, chopped pineapple residues. In conjunction with chemical control of developing larvae, adult trapping is an important control strategy. In this study, four blue-black fabric traps, Nzi, Vavoua, Model H, and Ngu, were compared with a white sticky trap currently used for stable fly control in Costa Rica. Overall, the white sticky trap caught the highest number of stable flies, followed by the Nzi, Vavoua, Model H, and Ngu. Collections on the white sticky trap increased 16 d after residues were chopped; coinciding with the expected emergence of flies developing in the pineapple residues. During this same time period, collections in the blue-black fabric traps decreased. Sex ratio decreased from >7:1 (females:males) 3-7 d after chopping to 1:1 at 24-28 d. White sticky, Nzi and Vavoua traps collected similar numbers of colonizing flies 3-7 d after residues were chopped. However, white sticky traps collected more flies once emergence from the pineapple residues began. Although white sticky traps collected more flies than fabric traps, they remain labor intensive and environmentally unsound because of their disposable and nonbiodegradable nature.

    Full Text Available Flies (Diptera, blow flies, house flies, flesh flies, horse flies, cattle flies, deer flies, midges and mosquitoes are among the four megadiverse insect orders. Several species quickly colonize human cadavers and are potentially useful in forensic studies. One of the major problems with carrion fly identification is the lack of taxonomists or available keys that can identify even the most common species sometimes resulting in erroneous identification. Here we present a key to the adults of 12 families of Diptera whose species are found on carrion, including human corpses. Also, a summary for the most common families of forensic importance in South America, along with a key to the most common species of Calliphoridae, Muscidae, and Fanniidae and to the genera of Sarcophagidae are provided. Drawings of the most important characters for identification are also included.Diptera (califorídeos, sarcofagídeos, motucas, moscas comuns e mosquitos é a uma das quatro ordens megadiversas de insetos. Diversas espécies desta ordem podem rapidamente colonizar cadáveres humanos e são de utilidade potencial para estudos de entomologia forense. Um dos maiores problemas com moscas que visitam matéria orgânica animal em decomposição é a falta de taxonomistas ou chaves de identificação disponíveis que possam identificar as espécies mais comuns ou mesmo, algumas vezes podendo resultar em identificações errôneas. Neste artigo é apresentada uma chave para adultos de 12 famílias de Diptera com espécies encontradas em matéria orgânica animal em decomposição, incluindo cadáveres humanos. Também é incluído um sumário das mais importantes famílias com espécies de interesse forense na América do Sul e chave de identificação das espécies mais comuns de Calliphoridae, Muscidae e Fanniidae e dos gêneros de Sarcophagidae.

    Full Text Available Abstract Background The task of recognizing and identifying species names in biomedical literature has recently been regarded as critical for a number of applications in text and data mining, including gene name recognition, species-specific document retrieval, and semantic enrichment of biomedical articles. Results In this paper we describe an open-source species name recognition and normalization software system, LINNAEUS, and evaluate its performance relative to several automatically generated biomedical corpora, as well as a novel corpus of full-text documents manually annotated for species mentions. LINNAEUS uses a dictionary-based approach (implemented as an efficient deterministic finite-state automaton to identify species names and a set of heuristics to resolve ambiguous mentions. When compared against our manually annotated corpus, LINNAEUS performs with 94% recall and 97% precision at the mention level, and 98% recall and 90% precision at the document level. Our system successfully solves the problem of disambiguating uncertain species mentions, with 97% of all mentions in PubMed Central full-text documents resolved to unambiguous NCBI taxonomy identifiers. Conclusions LINNAEUS is an open source, stand-alone software system capable of recognizing and normalizing species name mentions with speed and accuracy, and can therefore be integrated into a range of bioinformatics and text-mining applications.

    Full Text Available Abstract Carolus Linnaeus was totally unacquainted with the Edible Dormouse Myoxus glis (L., a species not found in Sweden: while describing Mus Rattus in the 10th Edition of the "Systema Naturae" (1758, the Swedish naturalist confessed his ignorance concerning the "Glis" of the ancients and suggested that it might have been the marmot or the hamster. Thanks to written information received from his correspondent in Slovenia, Giovanni Antonio Scopoli, Linnaeus was able to include the new species Sciurus Glis in his 12th Edition of the "Systema Naturae" (1766, reporting almost verbatim a summary of Scopoli's description of the rodent. Scopoli's letter is still preserved in the Library of the Linnean Society of London. The Linnean type locality "Habitat in Europa australi" for the Edible Dormouse Myoxus glis glis must therefore be restricted to "Southern Carniola, Slovenia", contra "Germany" as stated, for instance, by Miller (1912, Toschi (1965, Corbet (1978 and Storch (1978. A new name is required for the continental European form, for which M. glis germanicus ssp. nov. is here proposed. Some information on the appreciation of Myoxus glis as a delicacy ("carnes avide eduntur" in Linnaeus' words conclude the paper. Riassunto Carlo Linneo ed il Ghiro - Dopo aver descritto Mus Rattus nella decima edizione del "Systema Naturae" (1758 il naturalista svedese Carlo Linneo confessava di non essere a conoscenza del "Glis" degli antichi autori e ne suggeriva l'identificazione con la Marmotta o con il Criceto comune; è infatti noto che Myoxus glis non è diffuso in Svezia. In base ad una lettera ricevuta dal suo corrispondente in Slovenia, Giovanni Antonio Scopoli, Linneo fu in grado di descrivere questa nuova specie come Sciurus Glis nella dodicesima edizione del "Systema

  7. The mitochondrial genome of Elodia flavipalpis Aldrich (Diptera: Tachinidae and the evolutionary timescale of Tachinid flies.

    Full Text Available Tachinid flies are natural enemies of many lepidopteran and coleopteran pests of forests, crops, and fruit trees. In order to address the lack of genetic data in this economically important group, we sequenced the complete mitochondrial genome of the Palaearctic tachinid fly Elodia flavipalpis Aldrich, 1933. Usually found in Northern China and Japan, this species is one of the primary natural enemies of the leaf-roller moths (Tortricidae, which are major pests of various fruit trees. The 14,932-bp mitochondrial genome was typical of Diptera, with 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. However, its control region is only 105 bp in length, which is the shortest found so far in flies. In order to estimate dipteran evolutionary relationships, we conducted a phylogenetic analysis of 58 mitochondrial genomes from 23 families. Maximum-likelihood and Bayesian methods supported the monophyly of both Tachinidae and superfamily Oestroidea. Within the subsection Calyptratae, Muscidae was inferred as the sister group to Oestroidea. Within Oestroidea, Calliphoridae and Sarcophagidae formed a sister clade to Oestridae and Tachinidae. Using a Bayesian relaxed clock calibrated with fossil data, we estimated that Tachinidae originated in the middle Eocene.

    Sandy beaches are among the most impacted ecosystems worldwide, and the effects of urbanization on the biodiversity of these habitats are largely unknown, particularly in Brazil. We investigated the composition and structure of assemblages of sarcosaprophagous insects (Diptera: Calliphoridae, Sarcophagidae, and Muscidae) on six sandy beaches exposed to differential levels of human impact in Pernambuco State, Brazil. In total, 20,672 adults of 40 species were collected, of which 70% were Calliphoridae. Sarcophagidae had the highest diversity with 26 species of nine genera. A strong overlap in the composition of the assemblages across the six beaches was observed, with only a few species being restricted to one type of beach. The flesh flies Dexosarcophaga carvalhoi (Lopes), Peckia intermutans (Walker), and Titanogrypa larvicida (Lopes) occurred exclusively in beaches under low anthropogenic impact. Species with strong medical and veterinary importance such as Synthesiomyia nudiseta (Wulp) occurred even in beaches under low human presence. The invasive species Chrysomya albiceps (Wiedemann) and Chrysomya megacephala (F.) (Calliphoridae) were dominant in all beaches, which exposes the vulnerability of sandy beaches to exotic species. Our data imply that sarcosaprophagous flies can be used as early biological indicators to suggest urbanization in coastal environments. © The Authors 2017.

    A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from one of the pupae occurring within a week were identified as Exoristobia philippinensis Ashmead (Hymenoptera: Encyrtidae). Another observation was made whereby a pupa of C. rufifacies was predated by a muscid larva, Ophyra spinigera (Stein). The larva squeezed into the pupa and consumed the contents. This paper report C. rufifacies as a new host record for E. philippinensis in Malaysia and highlighted the predatory behavior of O. spinigera larva in natural environment.

The sample of 20 larvae from each 3 replicates were measured and weighed on 0-19th day (larva and 24th day (pupa from egg hatching. H. illucens adults were fed by water and honey 5% (v/v. Eggs were collected and counted. Nutrient content of immature stage: 5, 10, 15, 20 days old (larvae, and 25 days old (prepupae reared on PKM were analyzed proximately. Dry matter was determined by weight loss on drying at 105 oC during overnight. Crude protein was determined by Kjeldahl procedure (N x 6.25, crude fat by soxhlet (ether extract, crude ash by determining the residue after heating at 550 oC for 4–5 h. Data were analyzed descriptively by average from triplicate. The development of H. illucens was shorter than those in previous studies as the differences of abiotical factor. PKM was a suitable medium for development. It was better, however, to fed the adult with honey since it could enhance the fecundity. The young larva certainly contained the best quality of nutrition. To meet the quantity of mass production, however, the use of the elder larva (bigger was suggested.

    Increasing rates of unsolved homicides in Brazil prompt the need for applied entomological data to be used as a complementary tool by criminal investigators. In that context, we analyzed the occurrence of forensically important insect species (Order Diptera) on 14 cadavers taken into the Institute of Legal Medicine (ILM), in Pernambuco, Brazil, according to the conditions of the body and the pattern of colonisation by insects. Simultaneously, we surveyed the diversity of insects in the surrounding environment using bait traps. Five species were present on cadavers: Chrysomya albiceps, Chrysomya megacephala and Cochliomyia macellaria (Calliphoridae), Oxysarcodexia riograndensis and Ravinia belforti (Sarcophagidae). A total of 4689 adult insects belonging to 24 species of seven dipteran families (Calliphoridae, Sarcophagidae, Muscidae, Fanniidae, Phoridae, Anthomyiidae and Stratiomyidae) was collected at the ILM premises. C. albiceps was the most frequent species on the corpses and the most abundant in the traps. Species referred to as of forensic importance, such as Lucilia eximia, Chrysomya putoria, Oxysarcodexia modesta and Ophyra chalcogaster were collected on traps, but not on cadavers. There seems to be a limited colonisation of cadavers at the scene of the death, despite the ubiquity of necrophagous species in the area. The results contribute to differentiate between species that are involved in decomposition and those found in and around the mortuary installations of the ILM, thus providing potential clues about the locality of death and the post-mortem interval.

    Melophagus ovinus (Linnaeus 1758), Hippobosca equina Linnaeus, 1758, and Hippobosca longipennis Fabricius, 1805 (Diptera: Hippoboscidae) are economically and medically important ectoparasites that can act as mechanic vectors of pathogens and cause myiasis in both human and domestic animals. As essential olfactory organs, antennae of these adult hippoboscids were examined using stereoscopic and scanning electron microscopes. General morphology of the antenna is provided in detail, combined with distribution, types, size, and ultrastructures of antennal sensilla. On the antennal funiculus, two types of sensilla are observed, including basiconic sensilla and coeloconic sensilla. Four common characters are shared among the three species: (1) the scape is either obsolete or fused with the fronto-clypeus; (2) branched antennal structures (branched pedicellar microtrichiae and branched arista with only one segment) are detected; (3) the enlarged antennal pedicel completely envelops the antennal funiculus; and (4) less types of sensilla on funiculus. Disparity and diversity of the antennal and sensory structures are analyzed from the phylogenetic and functional perspective. We suggest that hippoboscids are potential model for the study of the function of coeloconic sensilla in Calyptratae.

    Full Text Available Inventories on necrophagous insects carried out in Brazil encompass mostly species from the southeastern and central-western regions of the country. This review aims to produce the first checklist of necrophagous Diptera and Coleoptera species of forensic relevance in northeastern Brazil, an area that concentrates high rates of homicides. We performed a literature survey on scientific articles, theses and dissertations regarding necrophagous insect species in the region, and contacted scientists who develop research on forensic entomology. Fifty-two species of Diptera belonging to eight families with previous record of necrophagy were reported in the region: Sarcophagidae, Calliphoridae, Muscidae, Fanniidae, Piophilidae, Phoridae, Anthomyiidae and Stratiomyidae. Coleopteran species from six families of forensic relevance were registered, although taxonomical identification remained superficial. Bait traps were the most frequent methodology used, followed by collection on animal carcasses. Seven Dipteran species from two families were registered on human cadavers. All species had been previously reported in other Brazilian states and/or other countries, although none has been effectively used in legal procedures in the region. The status of research on forensic entomology in northeastern Brazil is incipient, and the checklist produced here contributes to the knowledge on the local diversity of necrophagous insects.Inventários de insetos necrófagos no Brasil abordam em sua maioria espécies das regiões Sudeste e Centro-Oeste do país.

    Full Text Available Animal production units with different management systems can be found along the Huasco Valley, Region of Atacama, Chile. These constitute sources of house flies (Musca domestica L. and other vector fly species that cause damage to animals and nuisance problems in urban areas. In order to asses the importance of fly breeding sources, an experiment was carried out under laboratory conditions to evaluate different types of animal manure and composted swine manure. Time of larval development, larva mortality, pupa size, and weight and time of development to the adult stage were assessed. Results show that swine, poultry and calf manure produced a significantly higher number of adult flies, shorter life cycles and larger and heavier pupae. Cow, dog, goat and horse manure follow in effectiviveness for fly production. Composted swine manure was totally ineffective for domestic fly development.En algunas comunas del Valle del Huasco, Región de Atacama, Chile, se encuentran diversas explotaciones pecuarias con diferentes sistemas de manejo, las cuales constituyen focos generadores de mosca doméstica, Musca domestica L., y otras especies de moscas con importancia sanitaria y médica. Estos insectos provocan pérdidas económicas en dichos planteles afectando además el bienestar de poblaciones urbanas cercanas. Con el objetivo de cuantificar la importancia de dichos focos en la generación de mosca doméstica, se realizó un ensayo de laboratorio donde se evaluó como sustrato de desarrollo del insecto estiércol de diferentes especies animales y estiércol de cerdo compostado. La calidad de estos sustratos en la producción del insecto se evaluó a través de los siguientes parámetros biológicos: tiempo de desarrollo de larvas, mortalidad de larvas, tamaño y peso de pupas, y tiempo hasta la emergencia de moscas adultas. Los resultados indicaron que el estiércol de cerdo, gallina y ternero produce significativamente más moscas adultas, con un ciclo de vida más corto y con pupas de mayor tamaño y peso. Luego siguen en efectividad en la producción de moscas, el estiércol de vaca, perro, cabra y caballo. El compost de estiércol de cerdo fue completamente inefectivo para el desarrollo de mosca doméstica.

    Full Text Available The studies of insects from archaeological contexts can provide an important supplement of information to reconstruct past events, climate and environments. Furthermore, the list of the species present in an area in the past allows the reconstruction of the entomofauna on that area at that time, that can be different from the nowadays condition, providing information about biodiversity changes. In this work, the results of a funerary archaeoentomological study on samples collected from mummified corpses discovered during the restoration of the crypt of the Sant’Antonio Abate Cathedral of Castelsardo (Sardinia, Italy are reported. The majority of the sampled specimens were Diptera puparia, whereas only few Lepidoptera cocoons and some Coleoptera fragments were isolated. Among Diptera, Calliphoridae puparia were identified as Phormia regina (Meigen, 1826 and Calliphora vicina, (Robineau-Desvoidy, 1830 both species typical of the first colonization waves of exposed bodies. Three puparia fragments were also identified as belonging to a Sarcophaga Meigen, 1826, species (Sarcophagidae. Several Muscidae puparia of the species Hydrotaea capensis (Weidmermann, 1818, a late colonizer of bodies, and typical of buried bodies were also collected. The few moth (Lepidoptera cocoons were identified as belonging to the family Tineidae. This family comprises species feeding on dry tissues and hair typical of the later phases of the human decomposition. Among Coleoptera a single specimen in the family Histeridae, Saprinus semistriatus (Scriba, 1790 and a single elytra, potentially of a species in the family Tenebrionidae, were also collected. Overall, the samples collected indicated an initial colonization of the bodies in an exposed context, mainly in a warm season. This research allows the finding of elements indicating the presence, at least in the past, of P. regina in Sardinia. This species at the moment seems extinct from Sardinia while it is quite common

    We present a forensic case associated with skeletonized human remains found inside a cistern in a coastal town located in the eastern Iberian Peninsula (Valencian Regional Government, Spain). In order to analyse the particular environmental conditions that occurred during oviposition and development of the collected insects, estimated temperatures at the crime scene were calculated by a predictive mathematical model. This model analyses the correlation between the variability of the internal temperature depending on the variability of the external ones. The amplitude of the temperature oscillations inside the tank and the containment of the enclosure is reduced by the presence of water. Such variation occurred within about 2h due to the time required for heat exchange. The differential equations employed to model differences between outdoor and indoor temperatures were an essential tool which let us estimate the post-mortem interval (PMI) that was carried out by the study of the insect succession and the development time of the collected Diptera specimens under the adjusted temperatures. The presence of live larvae and pupae of Sarcophagidae and empty pupae of Calliphoridae, Sarcophagidae, Fanniidae, Muscidae, Phoridae and Piophilidae and the decomposition stage suggested the possibility that the remains were in the tank at least a year. We highlight the absence of Calliphora and Lucilia spp., and the first occurrence of the phorid Conicera similis in a human cadaver among the entomological evidence.

    Full Text Available The calyptrate dipterans are the most important decomposers of human cadavers. Knowledge of their species and distribution are of great importance to forensic entomology, especially because of the enormous diversity in Brazil. Carcasses of domestic pigs (Sus scrofa, L were the experimental models used to attract calyptrates of forensic interest during the winters of 2006 and 2007 and the summers of 2006 and 2008. A total of 24,423 specimens from 44 species were collected (19 Muscidae, 2 Fanniidae and 23 Sarcophagidae, three of which were new records of occurrence and 20 of which were new forensic records for the state of Rio de Janeiro. Fourteen of these species were newly identified as forensically important in Brazil.

    Full Text Available Porphyrio porphyrio (Fulica porphyrio Linnaeus was reported to the South Florida Water Management District in a Water Conservation Area and in constructed wetlands in the Everglades in 2006. A rapid assessment, including casual observations and surveys of land managers, indicated a limited number of P. porphyrio (~300 birds was present, and an eradication attempt was initiated. From 2006 – 2008, more than 3100 P. porphyrio were killed by shotgun from airboats during 73 hunts, suggesting the initial population assessment was severely underestimated. After removing nearly 1500 P. porphyrio in 2008, we concluded that eradication was not possible. Failure of this eradication attempt is attributed to P. porphyrio’s affinity with dense emergent vegetation, which greatly limited shooting effectiveness. Further, the failed eradication underscores the importance of a reporting network to improve early detection and the chance to eliminate naturalized or feral populations of non‐native species.

    Full Text Available Worm burdens were evaluated and compared in two groups of the guinea pig, Cavia poreellus (Linnaeus, 1758: animals of the first group were conventionally maintained in an institutional animal house and those of the second group were openly kept in pet shops in Brazil. Animals from both sources were infected only with the nematode Paraspidodera uncinata (Rudolphi, 1819 Travassos, 1914 (10% of prevalence in guinea pigs from lhe institutional facility and 40% in those animals from the pet shop. Other helminth samples recovered from Brazilian guinea pigs during 52 years and that are deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC were also analyzed. Paraspidodera uncinata and the cestode Monoecocestus parcitesticulatus Rêgo, 1960 were identified in these samples.

    The house fly (Musca domestica L.) is a well-established vector of human pathogens, including Campylobacter spp., which can cause infection of broiler chicken flocks, and through contaminated broiler meat can cause outbreaks of campylobacteriosis in humans. We investigated whether Campylobacter jejuni (Jones) could be transferred between life stages of M. domestica (larvae-pupae-adults) and determined bacterial counts of C. jejuni at different time points after bacterial exposure. C. jejuni was transmitted from infected larvae to pupae, but not to the adult stage. Infected larvae maintained at 25 degrees C had mean bacterial numbers of 6.5 +/- 0.2 SE log10 (colony forming units [CFU]/g) that subsequently dropped to 3.6 +/- 0.3 SE log10 (CFU/g) 8 h after infection. Pupae originating from infected larvae contained mean bacterial numbers of 5.3 +/- 0.1 SE log10 (CFU/g), and these numbers dropped to 4.8 +/- 0.1 SE log10 (CFU/g) 24 h after pupation. The decline in C. jejuni numbers during pupal development coincided with increased expression of antimicrobial peptides, including cecropin, diptericin, attacin, and defensin, in the larva-pupa transition stage and a later second peak in older pupae (4 or 48 h). Conversely, there was a reduced expression of the digestive enzyme, lysozyme, in pupae and adults compared with larvae.

    In this study, the toxicology of two commercial larvicides--cyromazine (Neporex 50SP) and ChCy (combination of chlorpyrifos and cypermethrin, Naga 505)--and five commercial adulticides--thiamethoxam (Agita 10WG), cyfluthrin (Responsar WP), lambda-cyhalothrin (Icon 2.8EC), fipronil (Regent 50SC), and imidacloprid (Toxilat 10WP)--was examined against the WHO/VCRU (World Health Organization/ Vector Control Research Unit) susceptible strain and the AYTW (Ayer Tawar) field strain of house fly, Musca domestica L. These pesticides were administered topically, in the diet, or as a dry residue treatment on plywood. Probit analysis using at least five concentrations and the concentration that was lethal to 50% (LC(50)) of the organisms was applied to compare the toxicology and resistance levels of the AYTW population to different insecticides. In the larvicide laboratory study, ChCy was more effective than cyromazine, with a significantly lower LC(50) value when administered topically or in the diet, although the AYTW population was susceptible to both larvicides with a resistance ratio (RR) <10. For the adulticide laboratory study, cyfluthrin and fipronil exhibited the lowest LC50 values of the adulticides, indicating that they are both effective at controlling adult flies, although lambda-cyhalothrin showed moderate resistance (RR = 11.60 by topical application; 12.41 by plywood treatment). Further investigation of ChCy, cyromazine, cyfluthrin, and fipronil under field conditions confirmed that ChCy and cyromazine strikingly reduced larval density, and surprisingly, ChCy also exhibited adulticidal activity, which significantly reduced adult fly numbers compared with the control group. Cyfluthrin and fipronil were also confirmed to be effective, with a significant reduction in adult fly numbers compared with the control group. © The Authors 2015.

    It is crucial to understand the degradation pattern of insecticides when designing a sustainable control program for the house fly, Musca domestica (L.), on poultry farms. The aim of this study was to determine the half-life and degradation rates of cyromazine, chlorpyrifos, and cypermethrin by spiking these insecticides into poultry manure, and then quantitatively analyzing the insecticide residue using ultra-performance liquid chromatography. The insecticides were later tested in the field in order to study the appropriate insecticidal treatment intervals. Bio-assays on manure samples were later tested at 3, 7, 10, and 15 d for bio-efficacy on susceptible house fly larvae. Degradation analysis demonstrated that cyromazine has the shortest half-life (3.01 d) compared with chlorpyrifos (4.36 d) and cypermethrin (3.75 d). Cyromazine also had a significantly greater degradation rate compared with chlorpyrifos and cypermethrin. For the field insecticidal treatment interval study, 10 d was the interval that had been determined for cyromazine due to its significantly lower residue; for ChCy (a mixture of chlorpyrifos and cypermethrin), the suggested interval was 7 d. Future work should focus on the effects of insecticide metabolites on targeted pests and the poultry manure environment.

    Full Text Available Abstract The viability of Aedes aegypti eggs was assessed in the Amazon region. The eggs were maintained under different conditions: indoors (insectarium and outdoors (natural environment, as well as in different storage types (plastic cup, paper envelope, plastic bag for different days. Egg viability was measured as the mean of hatchings observed from egg-bearing sheets of filter paper immersed in water, using three sheets randomly selected from each storage type and at both sites. There were significant differences in the viability of Ae. aegypti eggs with respect to the location (F=30.40; DF=1; P<0.0001, storage type (F=17.66; DF=2; P<0.0001, and time of storage (F=49.56; DF=9; P<0.0001. The interaction between storage site versus storage type was also significant (F=15.96; DF=2; P<0.0001. A higher hatching mean was observed for the eggs kept in the insectarium than for those outdoors (32.38 versus 7.46. Hatching rates of egg batches stored for 12 to 61 days ranged between 84 and 90%. A reduction was observed between 89 and 118 days, with values of 63 and 48%, respectively. With respect to type of storage, mean egg hatching was higher for the eggs in plastic cups (44.46. It was concluded that the viability of the eggs of Ae. aegypti in the Amazon region remains high up to 4 months, after which it declines drastically, although in this study hatching occurred for up to 8 months in very low percentages.

    Full Text Available BACKGROUND The epidemiological importance of the mosquito Aedes aegypti as a vector of multiple human pathogens has generated a growing number of studies on the physiology and behaviour of its blood-feeding females. The activity of oviposition is one of the critical elements contributing to the expansion of Ae. aegypti's populations. Although there is a vast literature about oviposition behaviour, significant specific knowledge about egg viability and female fertility under light and dark conditions is still lacking. OBJECTIVES We studied, in controlled laboratory conditions, the effect that light and dark cycles have on the efficiency of oviposition by Ae. aegypti females. METHODS Physiological assays were performed using synchronised eggs obtained from forced egg laying. The number and viability of eggs was analysed under three different light/dark regimes: LD12:12 (12 h of light and 12 h of dark, DD (constant darkness and LL (constant light. FINDINGS and CONCLUSIONS Our results show that females prefer to lay their eggs in dark conditions, but maximising the number and viability of eggs requires the occurrence of a light/dark cycle. Ongoing research on this theme has the potential of contributing to the proposition of new strategies for control based on the failure of egg laying and hatching.

  9. SEM studies on immature stages of the drone flies (diptera, syrphidae): Eristalis similis (Fallen, 1817) and Eristalis tenax (Linnaeus, 1758).

    Adult drone flies (Syrphidae: Eristalis spp.) resemble male honeybees in appearance. Their immature stages are commonly known as rat-tailed maggots due to the presence of a very long anal segment and a telescopic breathing tube. The larvae are associated with decaying organic material in liquid or semi-liquid media, as in the case of other saprophagous eristalines. Biological and morphological data were obtained from both laboratory cultures and sampling in the field. Drone flies are important pollinators for wild flowers and crops. In fact, mass rearing protocols of Eristalis species are being developed to be used as efficient alternative pollinators. However, deeper knowledge of larval morphology and biology is required to improve artificial rearing. The production quality control of artificial rearing must manage the consistency and reliability of the production output avoiding, for example contamination with similar species. This article presents the first description of the larva and puparium of E. similis, including a comparative morphological study of preimaginal stages of the anthropophilic and ubiquitous European hoverfly species E. tenax. Scanning electron microscopy has been used for the first time to describe larvae and puparia of both species. Moreover, the preimaginal morphology of E. similis has been compared with all known descriptions of the genus Eristalis. The main diagnostic characters of the preimaginal stages of E. similis are the morphology of the anterior spiracles (shape of clear area and arrangement of facets) and pupal spiracles (length, shape, and arrangement of tubercles).

  14. Histological description of Cerdocyon thous (Linnaeus, 1766 respiratory system

    Directory of Open Access Journals (Sweden)

    Marla P. Rocha

    Full Text Available ABSTRACT: The massive agricultural expansion converted the Cerdocyon thous, a South American native predator, in vulnerable specie. Basic data, such as histological description, are important to raise awareness on animal species, helping on preservation strategies. Considering the difficult in obtain samples, as the euthanasia of wild animals for this purpose is not allowed, data on histology are very scarce or inexistent. The objective of this paper was to provide a detailed histological description of the trachea and bronchial tree of the crab-eating fox Cerdocyon thous (Linnaeus, 1766. The specimens (one adult male and one adult female used were provided by the Federal University of Pelotas (Pelotas, RS, Brazil Rehabilitation Center of Wild Fauna (NURFS. Tissue samples were fixed in 10% formalin and included in paraffin. After slicing, samples were stained with HE (hematoxylin and eosin, PAS (periodic acid-Schiff and resorcin fuchsin. Trachea had an average diameter of 7.87mm, and approximately 57% of the mucosa ciliated pseudo-stratified columnar epithelium was composed of goblet cells, mostly in the dorsal region. Bronchia and bronchioles had a mucosal fold with higher number of goblet cells. Using all these techniques there is no great remarkable differences from C. thous trachea and lung, when compared with the previous described structures for carnivores and most mammals, except for the goblet cells “regionalization”. Described results are important to understand the animal physiological and behavioral habits, allowing the development of preservation and protection strategies.

  15. Homage to Linnaeus: How many parasites? How many hosts?

    Estimates of the total number of species that inhabit the Earth have increased significantly since Linnaeus's initial catalog of 20,000 species. The best recent estimates suggest that there are ≈6 million species. More emphasis has been placed on counts of free-living species than on parasitic species. We rectify this by quantifying the numbers and proportion of parasitic species. We estimate that there are between 75,000 and 300,000 helminth species parasitizing the vertebrates. We have no credible way of estimating how many parasitic protozoa, fungi, bacteria, and viruses exist. We estimate that between 3% and 5% of parasitic helminths are threatened with extinction in the next 50 to 100 years. Because patterns of parasite diversity do not clearly map onto patterns of host diversity, we can make very little prediction about geographical patterns of threat to parasites. If the threats reflect those experienced by avian hosts, then we expect climate change to be a major threat to the relatively small proportion of parasite diversity that lives in the polar and temperate regions, whereas habitat destruction will be the major threat to tropical parasite diversity. Recent studies of food webs suggest that ≈75% of the links in food webs involve a parasitic species; these links are vital for regulation of host abundance and potentially for reducing the impact of toxic pollutants. This implies that parasite extinctions may have unforeseen costs that impact the health and abundance of a large number of free-living species.

    Entomopathogenic fungi infect insects via penetration through the cuticle, which varies remarkably in chemical composition across species and life stages. Fungal infection involves the production of enzymes that hydrolyse cuticular proteins, chitin and lipids. Host specificity is associated with fungus-cuticle interactions related to substrate utilization and resistance to host-specific inhibitors. The soil fungus Conidiobolus coronatus (Constantin) (Entomophthorales: Ancylistaceae) shows virulence against susceptible species. The larvae and pupae of Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae), Calliphora vomitoria (Linnaeus), Lucilia sericata (Meigen) (Diptera: Calliphoridae) and Musca domestica (Linnaeus) (Diptera: Muscidae) are resistant, but adults exposed to C. coronatus quickly perish. Fungus was cultivated for 3 weeks in a minimal medium. Cell-free filtrate, for which activity of elastase, N-acetylglucosaminidase, chitobiosidase and lipase was determined, was used for in vitro hydrolysis of the cuticle from larvae, puparia and adults. Amounts of amino acids, N-glucosamine and fatty acids released were measured after 8 h of incubation. The effectiveness of fungal enzymes was correlated with concentrations of compounds detected in the cuticles of tested insects. Positive correlations suggest compounds used by the fungus as nutrients, whereas negative correlations may indicate compounds responsible for insect resistance. Adult deaths result from the ingestion of conidia or fungal excretions. © 2016 The Royal Entomological Society.

The study was carried out in biological incubators at 20, 25, 30 and 35-C; 65 ñ 10% relative humidity and 14 hours of photophase. The most favorable temperature for developing eggs, larval and pupal was 25-C, while 35-C proved to be harmful for a normal developing of S. calcitrans in larval stage. The incubation periods for egg were 69.90, 42.58, 26.10, 21.78 hours and 2.91, 1.77, 1.08, 0.90 days at 20, 25, 30, 35-C, respectively . The larval stage was 18.40, 11.63, 8.55 days and, the pupal stage, 8.60, 4.54, 3.60 days at 20, 25, 30-C, respectively. Threshold temperatures for males were a little higher than for females, however, this difference was lesser than 1-C. On the other hand, the quantity of energy (GD for developing females was a little higher than for males. No difference was observed between the two methods used for calculating the above mentioned biological parameters of S. calcitrans.

    Full Text Available Identification of insect species is an important task in forensic entomology. For more convenient species identification, the nucleotide sequences of cytochrome c oxidase subunit I (COI gene have been widely utilized. We analyzed full-length COI nucleotide sequences of 10 Muscidae and 6 Sarcophagidae fly species collected in Korea. After DNA extraction from collected flies, PCR amplification and automatic sequencing of the whole COI sequence were performed. Obtained sequences were analyzed for a phylogenetic tree and a distance matrix. Our data showed very low intraspecific sequence distances and species-level monophylies. However, sequence comparison with previously reported sequences revealed a few inconsistencies or paraphylies requiring further investigation. To the best of our knowledge, this study is the first report of COI nucleotide sequences from Hydrotaea occulta, Muscina angustifrons, Muscina pascuorum, Ophyra leucostoma, Sarcophaga haemorrhoidalis, Sarcophaga harpax, and Phaonia aureola.

    2012-12-01

    Classification was an important aspect of the 17th and 18th century development of Western science, epitomized by Linnaeus's 1735 Systema Naturae (Nature's System), in which he divided each kingdom of nature into classes, orders, and species. Linnaeus, a physician in addition to being a renowned taxonomist, endeavored to classify all known human diseases, largely on the basis of symptoms, in his 1759 Genera Morborum (Varieties of Diseases). We focus on his classification of mental disorders, a large subset of the Genera Morborum. We compare and contrast the Linnaean system with François Boissier de Sauvages's 1772 Nosologie méthodique (A Systematic Nosology) and Rudolph Augustin Vogel's 1764 Generum Morborum (Varieties of Diseases). We consider the impact of these nosologies on William Cullen's (1769/1800) Nosology, a popular system of disease classification that persisted through much of the 19th century.

    Full Text Available An unusual food plant for Cydia pomonella (Linnaeus (Lepidoptera, Tortricidae in Mexico. Larvae of Cydia pomonella (Linnaeus, 1758 were discovered on floral cones of Magnolia schiedeana (Schltdl, 1864 near the natural reserve of La Martinica, Veracruz, México. Magnolia represents an unusual host for this moth species, which is known throughout the world as the "codling moth", a serious pest of fruits of Rosaceae, especially apples. The larvae were identified using taxonomic keys, and identification was corroborated using molecular markers. Further sampling resulted in no additional larvae, hence, the observation was probably that of an ovipositional error by the female, and M. schiedeana is not at risk of attack by this important moth pest.

  7. Linnaeus' restless system: translation as textual engineering in eighteenth-century botany.

    Science.gov (United States)

    Dietz, Bettina

    2016-04-01

    In this essay, translations of Linnaeus' Systema naturae into various European languages will be placed into the context of successively expanded editions of Linnaeus' writings. The ambition and intention of most translators was not only to make the Systema naturae accessible for practical botanical use by a wider readership, but also to supplement and correct it, and thus to shape it. By recruiting more users, translations made a significant contribution to keeping the Systema up to date and thus maintaining its practical value for decades. The need to incorporate countless additions and corrections into an existing text, to document their provenance, to identify inconsistencies, and to refer to relevant observations, descriptions, and illustrations in the botanical literature all helped to develop and refine techniques of textual montage. This form of textual engineering, becoming increasingly complex with each translation cycle, shaped the external appearance of new editions of the Systema, and reflected the modular architecture of a botanical system designed for expansion.

    The hairy maggot blow fly Chrysomya rufifacies (Macquart) (Diptera: Calliphoridae) has expanded its range in the United States since its introduction into Texas (ca. 1980) and has been collected in 15 states. We investigated the bionomics of immature and adult C. rufifacies collected from carcasses of a raccoon Procyon lotor (Linnaeus) and white-tailed deer Odocoileus virginianus Zimmerman in Upstate South Carolina during November 2007, and used these insects to estimate the minimum period of insect activity. Puparia of C. rufifacies were collected from deer carrion; 28% were parasitized by Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae). The mean daily ambient temperature during this study was 11.4+/-1.02 degrees C, representing the lowest recorded mean temperature for adult activity of C. rufifacies; adults of C. rufifacies were observed flying among the carcasses at 9.0 degrees C. Although C. rufifacies is considered a warm-weather blow fly, researchers should be aware of its activity at suboptimal conditions, behavior that might aid its expansion into more northern areas. 2009 Elsevier Ireland Ltd.

The diversity of the Sarcophagidae fauna of the Cerrado biome, also know as the Brazilian Savanna, is still underestimated. In this research we collected flies in the state of Minas Gerais, Brazil, during a Forensic Entomology experiment. Samples were collected throughout the decomposition process of domestic pig (Sus scrofa Linnaeus carcasses, and the experiments were conducted in areas of pasture and semideciduous forest. A total of 85,694 adult flesh flies belonging to 57 species were collected from all carcasses. New records for nine species of Sarcophaginae are provided, including the first record of Blaesoxipha (Acridiophaga caridei (Brèthes, 1906 to Brazil, and new occurrences of the following species for the Cerrado and/or for the state of Minas Gerais: Blaesoxipha (Acanthodotheca acridiophagoides (Lopes & Downs, 1951, Malacophagomyia filamenta (Dodge, 1964, Nephochaetopteryx orbitalis (Curran & Walley, 1934, Nephochaetopteryx cyaneiventris Lopes, 1936, Nephochaetopteryx pallidiventris Townsend, 1934, Oxysarcodexia occulta Lopes, 1946, Ravinia effrenata (Walker, 1861 and Sarcophaga (Neobellieria polistensis (Hall, 1933.

    This study provides a parasitological analysis of the elasmobranch species caught in the northern and central Adriatic Sea. Sixty-two marine leeches were recorded on 747 individuals of Raja clavata Linnaeus, 1758 (thornback ray), Myliobatis aquila Linnaeus, 1758 (common eagle ray), and Torpedo marmorata Risso, 1810 (marbled torpedo ray) caught in 56 hauls over a 5 yr period. All leeches were identified as Pontobdella muricata, which is a typical ectoparasite of benthic elasmobranchs. The prevalence of infection ranged from 7.11% on R. clavata to 12.00% on M. aquila. The intensity of infection, the preferential sites of attachment to the host, and the periodicity of infection were evaluated.

Contudo, em virtude da grande diversidade de espécies, o trabalho de identificação apenas por características morfológicas torna-se difícil. A análise de DNA por meio de marcadores moleculares RAPD (Random Amplified Polymorphic DNA e DNA mitocondrial apresentam potencial para a identificação das espécies de insetos e poderão subsidiar a estimativa do intervalo post mortem (IPM. Os objetivos deste trabalho foram analisar a distribuição de frequência acumulada de insetos da ordem Diptera de interesse forense em uma localidade do Distrito Federal, visando gerar subsídios para estimativas do IPM e identificar indivíduos da espécie Chrysomya albiceps por marcadores RAPD e mitocondriais. Os resultados mostraram que o modelo logístico é adequado para descrever a distribuição de frequência acumulada de moscas das famílias Calliphoridae, Muscidae e Sarcophagidae. Além disso, um fragmento de RAPD de 580 pb e de DNAmt de 350 pb pode ser aplicado na identificação de C. albiceps. Assim, se estabeleceu um método molecular de identificação de uma espécie de interesse forense que poderá servir de auxílio na identificação de vestígios incompletos ou imaturos de dípteros.

    Full Text Available Dissection of 286 specimens of the "false" coral snake Erythrolamprus aesculapii Linnaeus, 1766, combined with data on captive individuais, provided information on the reproductive biology of this colubrid snake. Adult females (x snout-vent length = 74.5cm attain larger body size than males (x SVL = 62.6. Clutch size ranged from one to eight eggs and was correlated with maternal body size. Neonates measured 20.2-22.5cm SVL and weighed 5.1-5.8g. Males attain sexual maturity earlier than females. Reproduction seems to be aseasonal, with vitellogenesis occurring throughout the year. Apparently the growth rate of folheies decreases in the dry season, possibly due to lower tempeiatures during this period. Multiple clutches were recorded in captive snakes. Foraging strategies and availability of prey may explain continuous reproduction in E. aesculapii. However, data for other related snakes suggest that continuous reproduction is conservative in the Xenodontini.

  20. Carl Linnaeus, Erasmus Darwin and Anna Seward: Botanical Poetry and Female Education

    Science.gov (United States)

    George, Sam

    2014-03-01

    This article will explore the intersection between `literature' and `science' in one key area, the botanical poem with scientific notes. It reveals significant aspects of the way knowledge was gendered in the Enlightenment, which is relevant to the present-day education of girls in science. It aims to illustrate how members of the Lichfield Botanical Society (headed by Erasmus Darwin) became implicated in debates around the education of women in Linnaean botany. The Society's translations from Linnaeus inspired a new genre of women's educational writing, the botanical poem with scientific notes, which emerged at this time. It focuses in particular on a poem by Anna Seward and argues that significant problems regarding the representation of the Linnaean sexual system of botany are found in such works and that women in the culture of botany struggled to give voice to a subject which was judged improper for female education. The story of this unique poem and the surrounding controversies can teach us much about how gender impacted upon women's scientific writing in eighteenth century Britain, and how it shaped the language and terminology of botany in works for female education. In particular, it demonstrates how the sexuality of plants uncovered by Linnaeus is a paradigmatic illustration of how societal forces can simultaneously both constrict and stimulate women's involvement in science. Despite the vast changes to women's access in scientific knowledge of the present day, this `fair sexing' of botany illustrates the struggle that women have undergone to give voice to their botanical knowledge.

    2008-01-01

    Full Text Available This study presents a literature review of Drosophilidae (Diptera species occurrence in Brazil. The number of speciesrecorded is 304, with Drosophila being the genus with the greatest number of species, followed by Zygothrica,Hirtodrosophila and Diathoneura, which belong to the Drosophilinae subfamily. Drosophila was shown to be the mostinvestigated taxon in the family, with the best resolved species distribution. The low number of records of species fromother genera indicates the paucity of studies specifically designed to investigate these species. Records of species forsome regions of the country like the north and northeast, as well as for some biomes like Caatinga, Pantanal and thePampas, are likewise rare. Apart from the banana bait, different collection methods may be necessary, like thecollection at other oviposition resources, the use of baits other than fermenting fruit, and the adoption of samplingapproaches that do not use baits.

    Full Text Available The history of the classification of the Tachinidae (Diptera is traced from Meigen to the present. The contributions of Robineau-Desvoidy, Townsend, Villeneuve, Mesnil, Herting, Wood and many others are discussed within a chronological, taxonomic, and geographic context. The gradual development of the Tachinidae into its modern concept as a family of the Oestroidea and the emergence of the classificatory scheme of tribes and subfamilies in use today are reviewed. Certain taxa that have in the past been difficult to place, or continue to be of uncertain affinity, are considered and some are given in a table to show their varied historical treatments. The more significant systematic works published on the Tachinidae in recent decades are enumerated chronologically.

    Established procedures for collecting and preserving evidence are essential for all forensic disciplines to be accepted in court and by the forensic community at large. Entomological evidence, such as Diptera larvae, are primarily preserved in ethanol, which can evaporate over time, resulting in the dehydration of specimens. In this study, methods used for rehydrating specimens were compared. The changes in larval specimens with respect to larval length and weight for three forensically important blow fly (Diptera: Calliphoridae) species in North America were quantified. Phormia regina (Meigen), Cochliomyia macellaria (F.), and Chrysomya rufifacies (Macquart) third-instar larvae were collected from various decomposing animals and preserved with three preservation methods (80% ethanol, 70% isopropyl alcohol, and hot-water kill then 80% ethanol). Preservative solutions were allowed to evaporate. Rehydration was attempted with either of the following: 80% ethanol, commercial trisodium phosphate substitute solution, or 0.5% trisodium phosphate solution. All three methods partially restored weight and length of specimens recorded before preservation. Analysis of variance results indicated that effects of preservation, rehydration treatment, and collection animal were different in each species. The interaction between preservative method and rehydration treatment had a significant effect on both P. regina and C. macellaria larval length and weight. In addition, there was a significant interaction effect of collection animal on larval C. macellaria measurements. No significant effect was observed in C. rufifacies larval length or weight among the preservatives or treatments. These methods could be used to establish a standard operating procedure for dealing with dehydrated larval specimens in forensic investigations.

    This paper investigates polyphenol oxidase (PPO) activity, reduced weight percentage after sun drying, and the changes in colour and appearance of green pepper (Piper nigrum Linnaeus) berries after blanching and sun drying. The results show that the degree of reduced weight percentage and browning in green pepper berries after blanching for 10 min is greater at 100°C than at 90 and 80°C. Moreover, the samples blanched at 100°C for 10 min had the fastest water loss, but the lowest PPO activity. Thus, the PPO enzymatic oxidation of polyphenols might not be the only reason for the browning of green pepper berries. This result is significantly different from that of Variyar, Pendharkar, Banerjeea, and Bandyopadhyay (1988) and therefore deserves further study. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Influence of temperature on certain biological attributes of an aphidophagous ladybeetle, Coccinella septempunctata Linnaeus, feeding on mustard aphid, Lipaphis erysimi (Kaltenbach), at five different temperatures, viz. 20, 25, 27, 30 and 35℃ was investigated. Its developmental period was shortest (11.7±0.09days) at 35℃ and longest (20.6±0.35 days) at 20℃. Developmental rate increased with increase in temperature. Hatching percent, larval survival, adult emergence and growth index were maximum at 30℃ and minimumat 20℃. Oviposition period and fecundity were highest at 30℃ and lowest at 20℃. A positive linear relationship exists between temperature and developmental rate and negative correlation between the duration of immature life stages and temperature. The proportion of developmental period allocated to each immature stage was found to be similar at each temperature regime. Thus, 30℃ was found as the most suitable for C. septempunctata amongst the five temperatures tested.

    Material properties of the painted lady butterfly, Vanessa cardui Linnaeus were investigated using typical material science techniques. The examined butterflies were raised and hatched from the larvae stage and their chemical and crystalline structure evaluated and compared to that of crab shell (α-chitin) and squid pens from Notodarus sloanii and Loligo pealei (β-chitin). Fourier transmission infrared spectroscopy (FTIR) and X-ray diffraction (XRD) revealed that the painted lady butterflies are composed of α-chitin. Additionally, macro- and microstructure characterization of the chitins was conducted utilizing digital photography and field emission scanning electron microscopy (FESEM). This work demonstrates that common characterization techniques combined with simple sample preparation of biological materials can yield successful material characterization, which could aide the fabrication of biomimetic materials.

    This study describes the apicomplexa as well as other parasites infecting organs/tissues of the hard clam Meretrix meretrix Linnaeus, from Merambong Shoal, Western Johor Straits, Malaysia. Samples were collected randomly by hand picking, in November and December 2013. Histological techniques were performed, stained using Masson's Trichrome protocol and observed under light microscope. The results showed that gonad and gill were the most infected organs followed by digestive gland, intestine and adductor muscle. No pathology condition was observed in the mantle. Histophatological examination showed that the gregarine, Nematopsis, unidentified coccidian and Perkinsus were found in the gill and gonad, and also in the numerous hemocytes. Other pathological conditions such as bacteria-like inclusion and intracellular bacteria were also observed in the same organs. Further investigations are needed particularly on other molluscs present at the study area. Understanding the morphology and pathology of parasites infecting mollusks are very important for management of the resources.

    The occurrence of major outbreaks of dengue, and other vector borne diseases such as chikungunya and zika in tropical and subtropical regions has rendered control of the diseases a top-priority for many affected countries including Malaysia. Control of the mosquito vectors Aedes aegypti and Aedes albopictus through the reduction of breeding sites and the application of insecticides to kill immature forms and adults are the main control efforts to combat these diseases. The present study describes the association between Ae. albopictus and Ae. aegypti in shared breeding sites. This study is important given that any measure taken against one species may affect the other. A yearlong larval survey was conducted in four dengue endemic areas of Penang Island. Sorenson's coefficient index indicated that no association between number of the immatures of the two species regardless of container size and study location. Therefore, the mean number Ae. albopictus immature was not decreased in the presence of Ae. aegypti in shared breeding container. However Ae. aegypti appeared to prefer breeding in habitats not occupied by Ae. albopictus , the two species sharing breeding sites only where available containers were limited. In control efforts, eliminating the preferred breeding containers for one species might not affect or reduce the population of the other species.

    The objective of this work was to develop the methodology of the labeling adult of Musca domestica and Muscidifurax uniraptor using the elements Mn, Sr and Cu with the use of x-ray fluorescence. This work was carried out in the Laboratory of Biological Control of House Flies, 'Eduardo Hiroshi Mizumoto', of the 'Entomology, Phytopatology and Zoology Department of the College of Agriculture 'Luiz de Queiroz' ESALQ/USP), and the Division of Methods the Development and Nuclear Analytics Techniques, of CENA/USP, Piracicaba, Sao Paulo, Brazil. The larvae was removed to the labeled diet with increasing level of the elements Mn, Sr and Cu. The levels tested for all element were: 0 (control); 0,25; 0,50; 1,00; 2,00; 4,00; 8,00; 16,00; 32,00 and 64,00 mg/gr of diet. Labeled pupae with 1,00 to 4,00 (Mn) and 1,00 (Sr and Cu) mg/gr of diet were tested for the pupal parasitoid M. uniraptor. The concentration quantity of the chemical elements was realized by the Analytical Technique denominated (EDXRF) energy dispersive X-ray fluorescence. Concentrations of 2,00 (Mn) and 1,00 (Sr) supplemented to the diet of M. domestica were sufficient for the adult insect labeled, however, not affecting its life expectancy. Pupae originated from the larvae of M. domestica treated with dose of 2,00 (Mn) and 1,00 (Sr and Cu) mg supplemented to the diet, and used as hosts of the parasitoid M. uniraptor, affected the viability of the immature phase and did not label the adults.

    Full Text Available To investigate the kdr (knockdown resistance resistance-associated gene mutation and determine its frequency in pyrethroid-resistant horn fly (Haematobia irritans populations, a total of 1,804 horn flies of 37 different populations from all Brazilian regions (North, Northeast, Central-West, Southeast, and South were molecular screened through polymerase chain reaction (PCR. The kdr gene was not detected in 87.08% of the flies. However, the gene was amplified in 12.92% of the flies, of which 11.70% were resistant heterozygous and 1.22% were resistant homozygous. Deviation from Hardy-Weinberg equilibrium (HWE was found only in 1 ranch with an excess of heterozygous. When populations were grouped by region, three metapopulations showed significant deviations of HWE (Central-West population, South population and Southeast population. This indicates that populations are isolated one from another and kdr occurrence seems to be an independent effect probably reflecting the insecticide strategy used by each ranch. Although resistance to pyrethroids is disseminated throughout Brazil, only 48% of resistant populations had kdr flies, and the frequency of kdr individuals in each of these resistant populations was quite low. But this study shows that, with the apparent exception of the Northeast region, the kdr mechanism associated with pyrethroid resistance occurs all over Brazil.Com o objetivo de verificar a ocorrência e determinar a frequência da mutação kdr (knock down resistance em populações de Haematobia irritans (mosca-dos-chifres resistentes aos piretróides, foram analisados 1.804 indivíduos de 37 populações de todas as Regiões do Brasil. Com exceção da Região Nordeste, o kdr (knock down resistance gene foi encontrado em populações de todas as regiões. A mutação não foi detectada em 87,08% dos indivíduos. Entretanto, o gene foi amplificado de 12,92% das moscas, das quais 11,70% se mostraram heterozigotas resistentes e 1,22% homozigotas resistentes. Em todas as populações verificou-se equilíbrio de acordo com a Lei de Hardy e Weinberg, exceto uma com excesso de heterozigotos. Entretanto, quando agrupamos diferentes populações numa metapopulação de acordo com a região geográfica, é possível observar um desvio nas populações Centro-Oeste, Sul e Sudeste, indicando isolamento populacional e que a ocorrência do kdr é provavelmente um efeito independente, talvez refletindo a estratégia de uso do inseticida de cada produtor. Apesar da resistência aos piretróides estar disseminada por todo o país, apenas 48% das populações resistentes apresentaram o kdr, e a frequência de indivíduos kdr nas populações resistentes se mostrou bastante baixa. À exceção da Região Nordeste, o mecanismo de resistência ligado ao kdr ocorre em todo o país.

    The Directorate of Public Health (DPH), Tamil Nadu, in southern India employed spraying of dichlorvos (76% EC) for quick elimination of fly concentrations in the tsunami-hit coastal villages at the concentration of 304g (a.i.)/10,000m(2). However, nuisance of house flies remained high particularly in temporary shelters and centralized relief kitchens. Susceptibility of house fly, Musca domestica to dichlorvos was determined in the laboratory to provide information for an effective management of this pest. Various concentrations of dichlorvos (76% EC) viz., 0.1, 0.2, 0.4, 0.6 and 0.8microg (a.i.) per fly, were tested using topical application against F(1) progenies of house flies collected 12 months after insecticide applications from different habitats in the tsunami-hit coastal villages. Fly mortality was recorded at 24h post treatment. Parallel controls were maintained for comparison. Mortality of the house flies varied between 17.5% and 100% and increased with an increase in dosage of the insecticide. Mortality was >80% at 0.6 and 0.8microg (a.i.) per fly. The LD(50) of dichlorvos tested against flies collected from different villages varied from 0.218microg (a.i.) to 0.235microg (a.i.) per fly and the LD(90) varied from 0.574microg (a.i.) to 0.639microg (a.i.) per fly. House flies collected from a rural village, Thirukanur that had never been exposed for insecticide treatment in the past one decade, when tested, the mortality varied between 92.5% and 100% and increased with concentration of dichlorvos. Mortality was >90% from 0.2microg (a.i.) per fly and the LD(50) was 0.0399microg (a.i.)/fly, while the LD(90) was 0.1604microg (a.i.)/fly. The LD(90) values of the flies collected from the tsunami-hit villages were 3.5-3.9 times higher than that of the flies collected from Thirukanur. Fly abundance remained high in tsunami-hit villages with no marked reduction, suggesting that the flies had developed tolerance to dichlorvos. It is suggested that for an effective management of these resistant populations changing insecticides, application of unrelated insecticide, together with an appropriate environmental sanitation measure is necessary to keep the population under check.

General approaches on the behavior, ecology and physical abilities of this animal are available in the literature. However, information regarding different aspects of the anatomy of the nervous system giant anteater are sparsely found. Therefore, the morphological knowledge of the relationship between the spinal cord and vertebral column is of great importance to the scientific, as in the various species of animals, whether domestic or not, the relations of the caudal spinal differ. This difference comes out to meet the interests of wild animal medicine, especially as support for the practice of epidural anesthesia. Thus, the objective was to describe the topography of the conus M. tridactyla, providing anatomical data as a basis for the practice of epidural anesthesia.

    The population sizes of Anopheles gambiae Giles (Diptera: Culicidae) and Anopheles arabiensis Patton (Diptera: Culicidae) increase dramatically with the onset of the rainy season in sub-Saharan Africa, but the ecological mechanisms underlying the increases are not well understood. As a first step toward to understand, we investigated the proliferation of algae, the major food of mosquito larvae, in artificial fresh water bodies exposed to sunlight for a short period, and old water bodies exposed to sunlight for a long period, and the effects thereof on the development of these anopheline larvae. We found that an epizoic green algal species of the genus Rhopalosolen (Chlorophyta: Chlorophyceae) proliferated immediately after water freshly taken from a spring was placed in sunlight. This alga proliferated only briefly (for ~10 d) even if the water was repeatedly exposed to sunlight. However, various algal species were observed in water that remained under sunlight for 40 d or longer (i.e., in old water bodies). The growth performance of larvae was higher in sunlight-exposed (alga-rich) water than in shade-stored (alga-poor) water. Stable isotope analysis suggested that these two anopheline species fed on Rhopalosolen algae in fresh water bodies but hardly at all on other algae occurring in the old water bodies. We concluded that freshly formed ground water pools facilitate high production of anopheline species because of the proliferation of Rhopalosolen algae therein, and the increase in the number of such pools in the rainy season, followed by rapid increases in A. gambiae and A. arabiensis numbers. © The Author(s) 2018.

    Larvae of Empididae (Diptera) prey on black fly immatures and its pupae can be collected from pupal cases of Simuliidae (Diptera). The aim of our work was to report the second record of association between immatures of Empididae and Simuliidae in the Neotropical Region and the first for the Atlantic Forest (Rio de Janeiro, Brazil). We collected 4982 pupae and exuviae of Simulium Latreille, (Diptera, Simuliidae) and found three with a pupa of Hemerodromia Meigen (Diptera, Empididae) inside. This shows that the use of black flies cocoons by dance flies occurs at extremely low frequencies, which might explain why this association is so rarely recorded. Our results are relevant for a better comprehension of the predator-prey relationship between these families. Copyright © 2016 Elsevier B.V. All rights reserved.

    The stony coral Cladocora caespitosa (Linnaeus, 1767) is an important Mediterranean habitat builder, whose survival is now being threatened by human activities and possibly natural events such as mass mortality and bleaching. We characterized the mollusc assemblage associated with colonies in the Gulf of Trieste (northern Adriatic Sea) and then tested whether the number of mollusc species increases in relation with colony size, following a Species-Area Relationship (SAR) model. At least 62 taxa were found in association with coral colonies, with bivalves constituting the dominant group. More than half of the 3034 specimens encountered were juveniles. Mollusc taxa richness increased with increasing C. caespitosa colony size according to the power-function model, whilst the analyses of trophic and functional groups supports the hypothesis of at least two factors underlying SAR (area per se and habitat diversity). Our results confirmed the importance of C. caespitosa for benthic communities, indicating that larger colonies support higher biodiversity, and suggesting that C. caespitosa is the most important habit builder among Mediterranean cnidarians, having also an influential function as a natural nursery ground. These results underline the necessity of new investigations aimed at filling gaps in our knowledge and planning new measures to protect the species.

    Full Text Available In this study, it was aimed to determine the water-borne and food-borne boron accumulation in the liver and muscle tissues of Gold Fish (Carassius auratus Linnaeus, 1758. For each treatment, 12 individuals were. The water-borne boron treatments were applied as boron acid concentration of 1 mg/L, 10 mg/L and 20 mg/L in the aquarium water, while the food-borne boron treatments were prepared food contained the defined levels of boron (1 mg/kg, 5 mg/kg and 10 mg/kg as boric acid. The boron levels in the tissues were determined by an ICP-MS procedure. The maximum boron concentration was found in the 20mg/L water borne boron treatment in the liver tissue (1.78±0.02 mg/kg. In the water-borne boron treatments, the maximum Transfer Factor (TF was found in the 20mg/L boron concentration, and TF values were increased when the boron concentrations were decreasing. In the 1 mg/kg food-borne boron treatment, TF was found as 0, and increasing concentration of boron in the food caused an increase in TF reached about 0.06. This study suggested that the target organ for boron accumulation is the liver rather than the muscles and the accumulation of food-borne boron is lower when comparing water-borne boron.

    Full Text Available The purpose of this study was to provide reference data on the growth and population structure of brown trout Salmo (trutta trutta Linnaeus, in Central Italy. Standards for growth (percentiles and a standard growth model were developed from the von Bertalanffy growth model by using length-at-age data obtained from 122 sampling sites in the River Tiber basin. Length-frequency indices provide a numeric estimation for deviations of the population structure from a balanced population. We adapted the traditional North American Relative Stock Density (RSD and Proportional Stock Density (PSD indices to brown trout populations in Central Italy by means of two methods. In the first method, the benchmarks of length categories were established by using percentages applied to the largest individual in the dataset. In the second method, asymptotic length and size at maturity were used to define the length categories for index calculation. Both methods were tested on length-frequency data from 263 sampling sites in the River Tiber basin. The results showed that the PSD calculated by the first method provided a better insight into the population structures of brown trout. These results provide tools that will help ichthyologists and fish managers to compare the growth and population structure of brown trout throughout Central Italy.

    Dengue is an infectious viral disease, which can present a wide clinical picture, ranging from oligo or asymptomatic forms, to bleeding and shock, and can progress to death. The disease problem has increased in recent years, especially in urban and suburban areas of tropical and subtropical regions. There are five dengue viruses, called serotypes (DEN-1, DEN-2, DEN-3, DEN-4, and DEN-5), which belong to the Flaviviridae family and are transmitted to humans through infected mosquito bites, with the main vector the Aedes aegypti mosquito (Linnaeus, 1762). Studies performed with Ae. aegypti, aimed at their identification and analysis of their population structure, are fundamental to improve understanding of the epidemiology of dengue, as well for the definition of strategic actions that reduce the transmission of this disease. Therefore, considering the importance of such research to the development of programs to combat dengue, the present review considers the techniques used for the molecular identification, and evaluation of the genetic variability of Ae. aegypti.

    Full Text Available Resistance to chemotherapy occurs in various diseases (i.e., cancer and infection, and for this reason, both are very difficult to treat. Therefore, novel antimicrobial and chemotherapic drugs are needed for effective antibiotic therapy. The aim of the present study was to assess the antimicrobial and anti-proliferative effects of skin mucus derived from Dasyatis pastinaca (Linnaeus, 1758. Our results showed that skin mucus exhibited a significant and specific antibacterial activity against Gram-negative bacteria but not against Gram-positive bacteria. Furthermore, we also observed a significant antifungal activity against some strains of Candida spp. Concerning anti-proliferative activity, we showed that fish mucus was specifically toxic for acute leukemia cells (HL60 with an inhibition of proliferation in a dose dependent manner (about 52% at 1000 μg/mL of fish skin mucous, FSM. Moreover, we did not observe effects in healthy cells, in neuroblastoma cells (SH-SY5Y, and multiple myeloma cell lines (MM1, U266. Finally, it exhibited strong expression and activity of chitinase which may be responsible, at least in part, for the aforementioned results.

    Full Text Available Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767 snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 days. In the experiments, the snails moved on rock by continuous, direct, ditaxic, alternate undulations of the foot sole but on submerged sand they used slower arrhythmic discontinuous contractions of the foot sole. They switched between modes of locomotion in response to the type and topography of the substrate and possibly to water dynamics. In nature, snails moved between rocks forming aggregations where they oviposited. This may have masked other causes of movement, such as availability of prey. Most snails burrowed into the sand when the rocks became exposed during low tides. Further experiments are needed to explicitly address the possible causes of movements among rocks and burial.

    Full Text Available Red mullet, Mullus barbatus Linnaeus, 1758, is an economically very important species in trawl fisheries in the Adriatic Sea. Material for analysis was collected from October 2002 until May 2004 with a bottom trawl net from commercial trawlers on the Montenegrin shelf. Mortality of this species was analyzed for the first time in this area, sepa­rately for males and females and for both sexes together. Until now, only the spatial distribution and catch per unit of effort (CPUE of Mullus barbatus have been studied in Montenegrin waters. Estimated total mortality rates were Zmales = 0.653 and Zfemales = 0.712. The average mortality rate for both sexes was Z m+f = 0.749, while the natural mortality rate was Mm+f = 0.342. Values of Z in the Montenegrin shelf area are considerably lower than Z values for the Croatian and Italian parts of the Adriatic Sea, indicating that on the Montenegrin shelf fishing of this species is significantly less intensive than in other trawl-fishing areas of the Adriatic Sea.

    Full Text Available Toxic effects of essential plant oils in adult Sitophilus oryzae (Linnaeus (Coleoptera, Curculionidae. Stored grains are subject to losses in quality nutritional value and in sanitation from the time they are stored to the time they are consumed. Botanical insecticides may offer an alternative solution for pest control. The objective was to test the insecticidal properties of the essential oils of Cymbopogon citratus (leaf, Zingiber officinale (root and Mentha sp. (leaf. The efficacy of these oils was tested to control the rice weevil, S. oryzae, using hydrodistillation. Chemical analysis of the essential oils was carried out by gas chromatography. Major components of C. citratus were geranial (48% and neral (31%, of Z. officinale were α-zingibereno (13%, geranial (16%, neral (10% and α-farneseno (5% and of Mentha sp. was menthol (92%. Bioassays were carried out by fumigation and topical application. In topical application assays, the essential oil of C. citratus had greater toxicity (LC50 0.027 µL mL-1 and shorter exposure time than the oils of the other two plants. After 24 h and 48 h, 70% and 100% mortality of S. oryzae occurred, respectively. In fumigation assays, essential oil of Z. officinale had a lower LC50 (1.18 µL cm-2 and 70% mortality after 24 h exposure. Therefore, we recommend the use of essential oils of C. citratus and Z. officinale to control the rice weevil S. oryzae.

    Full Text Available The Chinese pangolin (Manis pentadactyla Linnaeus, 1758 is a critically endangered species, and documents on its captive breeding and reproductive parameters are scarce. MP8, kept in the Pangolin Research Base for Artificial Rescue and Conservation Breeding of South China Normal University (the PRB-SCNU, gave birth to a male offspring (MP86 on 19 October 2011. The baby pangolin was well developed, with a weight of 120 g and a total length of 23.2 cm. The gestation length of MP8 was estimated to be from 182 to 225d. Reproductive parameters of the Chinese pangolin are discussed based on collected data about this species. The Chinese pangolin has an obvious reproductive seasonality and its gestation length is typically six to seven months. In this observation, estrus and mating principally occurred in a one-year period from February to July. Parturition principally took place from September to February of the next year. Chinese pangolins usually give birth to one offspring at a time (n = 27. Sex ratio at birth was 0.71:1 (♀:♂, n = 12. Average weight for the reproducible females was 3.57 ± 1.38 kg (2.14–6.8 kg, n = 15. We estimated that Chinese pangolins could reach sexual maturity before they were one year old.

    Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) displays a lek mating system. Males form groups in which they simultaneously display signals (acoustical, visual, or chemical) to attract females with the purpose of mating. Females visit the lek and choose among signaling and courting males to mate. Scarce information is available in A. fraterculus about the main factors involved in female choice and the behavior of displaying males. This information could be important within the context of pest control programs with a sterile insect technique (SIT) component, because departures from normal sexual behavior caused by artificial rearing could affect males' performance in the field. In this study we assessed A. fraterculus male behavior within the leks and analyzed the importance of behavioral and morphological traits on their copulatory success. The existence of preferred places for lek formation was evaluated in field cages with trees inside and analyzed by dividing the trees in sectors according to a 3-dimensional system. Males were individually weighed, marked, and observed every 15 min. Morphometric and behavioral characteristics of successful and unsuccessful males were compared. Most successful males grouped in a region of the tree characterized by the highest light intensity in the first 2 h of the morning. Results showed that pheromone calling activity is positively associated with copulatory success. Copulations were more frequent for males calling inside the lek, indicating that pheromone calling activity and presence in the lek are key factors for copulatory success. A positive association between copulatory success and eye length was found; some characteristics of the face were also associated with copula duration and latency. (author) [es

    Full Text Available There are a few studies about predation on primates. Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil. Fingers and nails from Alouatta guariba clamitans Cabrera, 1940 were founded in two faecal samples from Leopardus pardalis (Linnaeus, 1758. With our documentation large howler monkey remains in faeces, the possibility of ocelot being a potential predator of all Neotropical primates should be taken into consideration.São poucos os estudos sobre a predação de primatas. Sendo os bugios animais relativamente grandes, acredita-se que somente médios e grandes carnívoros e grandes rapineiros possam lograr sucesso em sua predação. O estudo foi realizado na Chácara Payquerê, situada no município de Balsa Nova, Estado do Paraná, sul do Brasil. Dedos e unhas de Alouatta guariba clamitans Cabrera, 1940 foram encontradas em duas amostras fecais de Leopardus pardalis (Linnaeus, 1758 que foram coletadas. Com este registro de grande primata em fezes, a possibilidade de a jaguatirica ser um potencial predador de todos os primatas neotropicais pode ser levada em consideração.

    Full Text Available Jatropha curcas Linnaeus (piñón botija, considerada la gran promesa verde para el biodiesel, es una planta de la que existen considerables incógnitas en el ámbito científico desde el punto de vista agronómico, sobre todo en lo referente a los microorganismos causantes de enfermedades, entre las que sobresale la conocida como damping off (estrangulamiento de las plántulas que es provocada por varias especies de hongos. Por ello, el objetivo de este artículo es compilar la mayor cantidad de información sobre los principales microorganismos fitopatógenos que afectan a J. curcas, así como las posibles estrategias para su manejo, con el fin de obtener rendimientos eficientes y rentables de este cultivo energético en Cuba. Se encontraron 48 agentes causales de enfermedades; los más representativos fueron los hongos, entre los que predominan los que producen la roya y el mildiu polvoso, fundamentalmente. En cuanto al manejo fitosanitario, se citan las medidas culturales preventivas y las químicas, como curativas. De ahí que en Cuba, al igual que en otros países donde se cultiva el piñón botija, sea imprescindible conocer los fitopatógenos que pueden reducir los rendimientos de dicha planta, para después implementar un sistema de manejo fitosanitario que contribuya a evitar pérdidas considerables en la producción de biodiesel como producto final.

    Full Text Available Chromosome morphometry and nuclear DNA content are useful data for cytotaxonomy and to understand the evolutionary history of different taxa. For the genus Bromus Linnaeus, 1753, distinct ploidy levels have been reported, occurring from diploid to duodecaploid species. The geographic distribution of Bromus species has been correlated with chromosome number and ploidy level. In this study, the aims were to determine the nuclear genome size and characterize the karyotype of the South American Bromus species: Bromus auleticus Trinius ex Nees, 1829, Bromus brachyanthera Döll, 1878 and Bromus catharticus Vahl, 1791. The mean nuclear 2C value ranged from 2C = 12.64 pg for B. catharticus to 2C = 17.92 pg for B. auleticus, meaning a maximum variation of 2C = 5.28 pg, equivalent to 41.70%. Despite this significant difference in 2C value, the three species exhibit the same chromosome number, 2n = 6x = 42, which confirms their hexaploid origin. Corroborating the genome size, the chromosome morphometry (total, short- and long-arm length and, consequently, the class differed among the karyotypes of the species. Based on the first karyograms for these Bromus species, some morphologically similar and several distinct chromosome pairs were found. Therefore, the karyotype characterization confirmed the hexaploid origin of the studied Bromus species, which differ in relation to the karyogram and the nuclear 2C value. Considering this, cytogenetics and flow cytometry can be used to discriminate Bromus species, contributing to taxonomy and systematic studies and providing information on the evolutionary history of this taxa.

    Full Text Available Adaptation mechanisms as response to water content, oxygen level and pollutants are very important and they can be interpreted by hematological analysis. The aim of this study was the analysis of hematological and immune adaptations of common carp (Cyprinus carpio Linnaeus, 1758 to thermal stress. All specimens were divided into a control and experimental group. The control group of fish was exposed to a constant water temperature of 10°C. We induced thermal stress in experimental fish by gradually heating water to 28°C, held for 30 minutes and then comparing the obtained results with the control fish. Short-term hyperthermia lead to an increase of the number of leukocytes, especially pseudoeosinophilic granulocytes and monocytes, while the number of neutrophils and lymphocytes was reduced. The analysis of the leukocyte number and differential blood count in the control group showed high individual variation of segmented granulocytes, monocytes and pseudoeosinophilic granulocytes. Statistically significant differences (p=0.00 were found for the white blood cells, nonsegmented neutrophils and pseudoeosinophils between the control and experimental group. The experimental group of males had an increased number of white blood cells, monocytes and pseudoeosinophils, where significant differences were found for nonsegmented and total neutrophils and also for pseudoeosinophils (p=0.00, lymphocytes (p=0.01 and monocytes (p=0.03. Females had an increased total number of white blood cells, lymphocytes, monocytes and pseudoeosinophils, while significant differences (p=0.00 were obtained in the number of white blood cells, non segmented and total neutrophils and pseudoeosinophils between the control and experimental group. Adaptation mechanisms in carp after water temperature heating are mostly reflected in the increase of pseudoeosinophils and the decrease of neutrophils.

    The work describes the uptake, retention/biological elimination and organ/tissue distribution of 137 Cs by freshwater Japanese catfish (Silurus asotus Linnaeus) under laboratory conditions. The fish were divided into three groups based on their size and age and reared in 137 Cs-spiked water. The concentration of 137 Cs in the whole body of the live fish was measured at regular intervals up to 60 days. A significant accumulation of 137 Cs was found, but a steady state condition was not achieved by the end of the experiment. The bioaccumulation factors at steady state and the required time to reach steady state were estimated to be 1.55 and 255 days, 1.76 and 180 days and 1.99 and 160 days for large, medium and small size fish, respectively. To determine the effective half-life of 137 Cs, the fish were transferred and reared in the non-contaminated host water. The concentration of the remaining 137 Cs in the whole body of the live fish was measured up to 66 days. The average effective half-life of 137 Cs in the fish species was found to be ∼142 days for fish of all sizes. The distribution of 137 Cs in different organs/tissues of the fish was determined. Accumulation of 137 Cs in muscle/flesh of the fish was found to be ∼75% of whole body accumulation. The uptake rate and the retention capability of juvenile fish were found to be higher and therefore, these were more susceptible to 137 Cs than adult and old fish, and could be an important source of 137 Cs in the human food chain

    Curcuminoid from Curcuma longa Linnaeus has been demonstrated to be effective in anti-cancer and anti-inflammation. The objectives of the present study were to prepare curcuminoid dispersion and nanoemulsion from C. longa and determine their oral bioavailabilities in rats. After curcuminoid extraction using 99.5% ethanol, bisdemethoxycurcumin (BDMC), demethoxycurcumin (DMC) and curcumin were separated within 10 min by high-performance liquid chromatography using an Eclipse XDB-C18 column (Agilent, Palo Alto, CA, USA) and a gradient mobile phase of 0.1% aqueous formic acid and acetonitrile, with a flow rate of 1 mL min -1 , column temperature of 35 °C and detection wavelength of 425 nm. Curcuminoid nanoemulsion at a particle size of 12.1 nm and encapsulation efficiency 98.8% was prepared using lecithin, Tween 80 and water. A pharmacokinetic study in rats revealed that the parameters including T max , C max , t 1/2 and the area under the curve were higher for curcuminoid nanoemulsions than for curcuminoid dispersion at the same dose employed for gavage administration, whereas, for intravenous injection, an opposite trend was shown. The oral bioavailabilities of BDMC, DMC, curcumin and total curcuminoids in nanoemulsion and dispersion were 34.39 and 4.65%, 39.93 and 5.49%, 47.82 and 9.38%, and 46 and 8.7%, respectively. The results of the present study demonstrate a higher oral bioavailability after incorporation of curcuminoid into nanoemulsion, facilitating its application as a botanic drug. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Euploidy plays an important role in the evolution and diversification of Psidium Linnaeus, 1753. However, few data about the nuclear DNA content, chromosome characterization (morphometry and class) and molecular markers have been reported for this genus. In this context, the present study aims to shed light on the genome of Psidium guineense Swartz, 1788, comparing it with Psidium guajava Linnaeus, 1753. Using flow cytometry, the nuclear 2C value of Psidium guineense was 2C = 1.85 picograms (pg), and the karyotype showed 2n = 4x = 44 chromosomes. Thus, Psidium guineense has four chromosome sets, in accordance with the basic chromosome number of Psidium (x = 11). In addition, karyomorphometric analysis revealed morphologically identical chromosome groups in the karyotype of Psidium guineense. The high transferability of microsatellites (98.6%) further corroborates with phylogenetic relationship between Psidium guajava and Psidium guineense. Based on the data regarding nuclear genome size, karyotype morphometry and molecular markers of Psidium guineense and Psidium guajava (2C = 0.95 pg, 2n = 2x = 22 chromosomes), Psidium guineense is a tetraploid species. These data reveal the role of euploidy in the diversification of the genus Psidium.

    Full Text Available In this paper, detailed meiotic analysis was investigated in seven species of Curcuma (Linnaeus, 1753 which can contribute significantly to our understanding about species inter-relationship, speciation and evolution. The species were divided into two groups viz., Group I having 2n = 42 (C. comosa Roxburgh, 1810, C. haritha Mangaly & M.Sabu, 1993, C. mangga Valeton & Zijp, 1917, and C. motana Roxburgh, 1800 and Group II with 2n = 63 (C. caesia Roxburgh, 1810, C. longa Linnaeus, 1753 and C. sylvatica Valeton, 1918. Both groups display varying degree of chromosome associations. Group I species showed the prevalence of bivalents, however occasional quadrivalents besides univalents were also encountered. About 48% of the PMCs analyzed in C. mangga showed 21 bivalents (II meiotic configurations, 32% in C. comosa and 16% in C. haritha. Group II species as expected showed the presence of trivalents besides bivalents, univalents and quadrivalents. About 32% of the PMCs analyzed at MI in C. sylvatica showed 21 trivalents (III meiotic configurations, 24% in C. longa and 8% in C. caesia. Overall, low frequency of multivalent associations as compared to bivalents indicates that Curcuma is an allopolyploid complex. Moreover, x = 21 is too high a basic number, therefore, we suggest that the genus Curcuma has evolved by hybridization of species with different chromosome numbers of 2n = 24 and 18, resulting in a dibasic amphidiploid species.

    Full Text Available Abstract Background The control of onchocerciasis in the African region is currently based mainly on the mass drug administration of ivermectin. Whilst this has been found to limit morbidity, it does not stop transmission. In the absence of a macrofilaricide, there is a need for an integrated approach for disease management, which includes vector control. Vector control using chemical insecticides is expensive to apply, and therefore the use of other measures such as biological control agents is needed. Immature stages of Simulium squamosum, reared in the laboratory from egg masses collected from the field at Boti Falls and Huhunya (River Pawnpawn in Ghana, were observed to be attacked and fed upon by larvae of the chironomid Cardiocladius oliffi Freeman, 1956 (Diptera: Chironomidae. Methods Cardiocladius oliffi was successfully reared in the rearing system developed for S. damnosum s.l. and evaluated for its importance as a biological control agent in the laboratory. Results Even at a ratio of one C. oliffi to five S. squamosum, they caused a significant decrease in the number of adult S. squamosum emerging from the systems (treatments. Predation was confirmed by the amplification of Simulium DNA from C. oliffi observed to have fed on S. squamosum pupae. The study also established that the chironomid flies could successfully complete their development on a fish food diet only. Conclusion Cardiocladius oliffi has been demonstrated as potential biological control agent against S. squamosum.

    Full Text Available Considerando a importância da paca (Cuniculus paca, Linnaeus, 1766, tanto como fonte proteica alternativa para a população quanto pela possibilidade de vir a se tornar um animal de experimentação e pela falta de informações sobre a sua anatomia, objetivou-se descrever a morfologia macroscópica e histológica do estômago e do duodeno desse roedor, reconhecendo as relações, forma e posição que esses órgãos estabelecem entre si e com outros órgãos. O estômago da paca é unicavitário, está no plano médio mais voltado para o antímero esquerdo, transversalmente, na região hipocôndrica em posição ventrocaudal, interposto entre o esôfago e o duodeno. O duodeno da paca se inicia em sequência ao estômago, segue caudalmente até o nível da quinta ou sexta vértebra lombar, na altura das quais se curva e toma direção cranial, dirigindo-se até o nível da transição entre a última vértebra torácica e a primeira vértebra lombar, onde se continua como jejuno. Histologicamente, o estômago e o duodeno da paca possuem o padrão característico da arquitetura dos órgãos ocos, apresentando as seguintes túnicas: mucosa, submucosa, muscular e serosa. Da forma que se conduziu este estudo, conclui-se que o estômago e duodeno da paca, de forma geral, possuem características morfológicas macroscópicas e histológicas semelhantes às dos animais domésticos e de outros roedores selvagens.

    Full Text Available A criação de avestruz (Struthio camelus, Linnaeus 1758 é uma atividade de grande potencial, porém não existem padrões definidos sobre a histologia do seu fígado, que é um órgão de grande importância no metabolismo. O conhecimento de sua histologia pode contribuir para a detecção de doenças e deficiências nutricionais no animal. Para este estudo foram utilizados 24 avestruzes com idades entre 12 e 18 meses (com peso médio em torno de 80 a 100 kg, provenientes do abatedouro Don Pig, em Botucatu no estado de São Paulo. Os animais foram abatidos com pistola pneumática e, após a sangria, as amostras do fígado foram processadas e observadas em microscopia de luz e microscopia eletrônica de transmissão (MET. A hematoxilina e eosina (H.E, picrossírius, Gordon e Sweets, Sudan black e o ácido peródico de Schiff (PAS são colorações usadas respectivamente para observar a morfologia do fígado, colágeno, fibras reticulares, gordura e glicogênio. Foram encontrados os espaços portahepáticos.O glicogênio mostrou média de 5,68%, o conteúdo lipídico, média de 9,83%, o colágeno média de 14,71% e as fibras reticulares média de 5,96%. Quanto à MET notou-se no citoplasma dos hepatócitos, numerosas mitocôndrias, glicogênio, muitas gotas de gordura, alguns lisossomos, retículo endoplasmático granular ao redor das mitocôndrias, algumas células estreladas, célula em degeneração e o canalículo biliar ao centro. Provavelmente o quadro sugestivo de esteatose é resultante do estado nutricional dos animais. Estes resultados demonstraram que os hepatócitos dos avestruzes são muito similares às outras aves, como também muito semelhantes à estrutura e ultraestrutura das células do fígado de mamíferos.

    The complete mitogenome of the horse stomach bot fly Gasterophilus pecorum (Fabricius) and a near-complete mitogenome of Wohlfahrt's wound myiasis fly Wohlfahrtia magnifica (Schiner) were sequenced. The mitogenomes contain the typical 37 mitogenes found in metazoans, organized in the same order and orientation as in other cyclorrhaphan Diptera. Phylogenetic analyses of mitogenomes from 38 calyptrate taxa with and without two non-calyptrate outgroups were performed using Bayesian Inference and Maximum Likelihood. Three sub-analyses were performed on the concatenated data: (1) not partitioned; (2) partitioned by gene; (3) 3rd codon positions of protein-coding genes omitted. We estimated the contribution of each of the mitochondrial genes for phylogenetic analysis, as well as the effect of some popular methodologies on calyptrate phylogeny reconstruction. In the favoured trees, the Oestroidea are nested within the muscoid grade. Relationships at the family level within Oestroidea are (remaining Calliphoridae (Sarcophagidae (Oestridae, Pollenia + Tachinidae))). Our mito-phylogenetic reconstruction of the Calyptratae presents the most extensive taxon coverage so far, and the risk of long-branch attraction is reduced by an appropriate selection of outgroups. We find that in the Calyptratae the ND2, ND5, ND1, COIII, and COI genes are more phylogenetically informative compared with other mitochondrial protein-coding genes. Our study provides evidence that data partitioning and the inclusion of conserved tRNA genes have little influence on calyptrate phylogeny reconstruction, and that the 3rd codon positions of protein-coding genes are not saturated and therefore should be included.

    Ascaridia galli (Schrank, 1788) is a common parasite of various galliform birds worldwide. Although A. galli has been extensively studied by many author, knowledge of the morphology of this species in detail is still insufficient. In the present paper, the detailed morphology of A. galli was further studied using light and scanning electron microscopy, based on specimens collected from the endangered green peafowl Pavo muticus Linnaeus (Galliformes: Phasianidae) in China. The results revealed some erroneous and previously unreported morphological features, including the lips lacking real denticles, the lateral alae beginning at some distance posterior to the base of the ventrolateral lips and the caudal papillae with 4 different morphotypes. The present morphological and morphometric data complement previous descriptions and enable us to recognize this species more precisely.

A espécie L. migonei quando alimentada com sangue de hamster e frango apresentaram maior fecundidade do que as fêmeas de L. ovallesi, a maior fecundidade foi com sangue de frango. A presença de Leishmania no sangue de frango ou sangue de hamster diminuiu significativamente o seu consumo, o que resultou na diminuição da sobrevida das fêmeas após a oviposição em L. migonei alimentados com sangue de frango e não com sangue de hamsters. Entretanto, não afetar a quantidade de sangue e a sobrevivência de oviposição de L. ovallesi. A infecção com L. amazonensis causo um aumento no número de ovos retidos e diminuiu o número de ovos postos por L. migonei e L. ovallesi, especialmente com sangue de frango e também reduz o tempo de digestão do sangue em ambas as espécies com sangue de frango, mas não com sangue de hamster. Embora o sangue de frango foi menos eficaz do que o sangue de hamster sobre o potencial biológico de L. migonei e L. ovallesi, não exclui o sangue de frango como uma fonte de sangue para a manutenção das populações de ambas as espécies nas casas.

  4. Impact of elevated levels of atmospheric CO2 and herbivory on flavonoids of soybean (Glycine max Linnaeus).

    Atmospheric levels of carbon dioxide (CO2) have been increasing steadily over the last century. Plants grown under elevated CO2 conditions experience physiological changes, particularly in phytochemical content, that can influence their suitability as food for insects. Flavonoids are important plant defense compounds and antioxidants that can have a large effect on leaf palatability and herbivore longevity. In this study, flavonoid content was examined in foliage of soybean (Glycine max Linnaeus) grown under ambient and elevated levels of CO2 and subjected to damage by herbivores in three feeding guilds: leaf skeletonizer (Popillia japonica Newman), leaf chewer (Vanessa cardui Linnaeus), and phloem feeder (Aphis glycines Matsumura). Flavonoid content also was examined in foliage of soybean grown under ambient and elevated levels of O3 and subjected to damage by the leaf skeletonizer P. japonica. The presence of the isoflavones genistein and daidzein and the flavonols quercetin and kaempferol was confirmed in all plants examined, as were their glycosides. All compounds significantly increased in concentration as the growing season progressed. Concentrations of quercetin glycosides were higher in plants grown under elevated levels of CO2. The majority of compounds in foliage were induced in response to leaf skeletonization damage but remained unchanged in response to non-skeletonizing feeding or phloem-feeding. Most compounds increased in concentration in plants grown under elevated levels of O3. Insects feeding on G. max foliage growing under elevated levels of CO2 may derive additional antioxidant benefits from their host plants as a consequence of the change in ratios of flavonoid classes. This nutritional benefit could lead to increased herbivore longevity and increased damage to soybean (and perhaps other crop plants) in the future.

    Weekly monitoring of forensically important flight-active blow flies (Diptera: Calliphoridae) and flesh flies (Diptera: Sarcophagidae) was performed using small baited traps. Sampling took place in two rural, one suburban and two urban habitats in and around Frankfurt (Main), Germany, lasting two years and eight months. Highest values for species richness and Chao-Shen entropy estimator for Shannon's index in both families were found at the urban sites, peaking during summer. Space-time interaction was tested and found to be significant, demonstrating the value of a statistical approach recently developed for community surveys in ecology. K-means partitioning and analysis of indicator species gave significant temporal and habitat associations of particular taxa. Calliphora vicina was an indicator species for lower temperatures without being associated with a particular habitat. Lucilia sericata was an indicator for urban sites, whereas Lucilia ampullacea and Lucilia caesar were indicators for rural sites, supplemented by the less frequent species Calliphora vomitoria. Sarcophagidae were observed during a clearly shorter period of year. Sarcophaga subvicina+Sarcophaga variegata was found to be an indicator for urban habitats during summer as well as Sarcophaga albiceps for rural habitats. A significant association of Sarcophaga caerulescens to rural habitats as well as one of Sarcophaga similis to urban habitats was observed. Copyright © 2013 Elsevier Ireland Ltd.

    SUMMARY: A population study of the box turtle (Terrapene c. carolina Linnaeus) was made during the years 1944 to 1947 at the Patuxent Research Refuge, Maryland. A thirty acre area in well drained bottomland forest on the flood plain of the Patuxent River was selected for intensive study. Similarly forested land extended in all directions from the study plot. Markers were established at eighty-three foot intervals over the study plot for reference in recording locality data. Individuals were marked by filing notches in the marginal scutes according to a code system. There were 2109 collections of study area turtles. Records of collecting sites and turtle behavior showed that in the bottomlands habitat cover is utilized extensively during the day as well as at night. Turtles not actively moving about are almost always found in or around brush piles, heaps of debris, and tangles of vines and briars. Gully banks and woods openings are used for sunning. Turtles are occasionally found in the mud or water of the gullies. The commonest type of night retreat is a cavity constructed by the turtle in leaves, debris, or earth. These cavities, termed 'forms,' may be used only once, but are sometimes used repeatedly, often at intervals of several days or more. Different turtles sometimes use the same form on successive nights. Weather conditions most favorable to turtle activity are high humidity, warm sunny days, and frequent rains. The most unfavorable influences are low temperatures and drought. On most summer days there are some active turtles but individual turtles are not active every day. Periods of activity are alternated with periods of quiet even in favorable weather. This behavior is most pronounced in early spring and late fall when inactive days are often more numerous than active ones. Adult turtles occupy specific home ranges which they maintain from year to year. The turtles living in the study plot retained their ranges even through a flood that completely

    A population study of Terrapene carolina (Linnaeus) was made at the Patuxent Research Refuge, Maryland, from 1944 to 1947. A thirty acre area in bottomland forest was selected for intensive study. Turtles were marked by filing notches in marginal scutes according to a code. Turtles make extensive use of brushy shelter during the day as well.as at night. Gully banks and woods openings are used for sunning. Nights are usually spent in a 'form,' constructed by the turtle in leaves, debris, or earth. A form may be used once or it may be used repeatedly by the same or different turtles. Weather conditions most favorable to turtle activity are high humidity, warm sunny days, and frequent rains. Periods of activity are alternated with periods of quiet, even in favorable weather. There is no evidence for territorialism. Ranges of turtles of all ages and both sexes overlap grossly. Turtles are frequently found near each other but no antagonistic behavior has been observed. Adult turtles occupy specific home ranges which they maintain from year to year. Turtles retained their ranges even though a flood that completely covered the study area. Maximum home range diameters were determined by measurements of the mapped ranges of individual turtles. There was no significant difference between sizes of male and female ranges: males 33O+ 26 feet, females 37O+29 feet. A trail-laying device was used in following travel routes for 456 turtle days. Normal movements within the home range are characterized by (1) turns, doublings, detours, and criss-crossing paths, (2) interspersion of fairly direct traverses of the home range, (3) frequently repeated travels over certain routes. Maximum limits of the home range are ordinarily reached within a few days or weeks, although some turtles cover only one portion of the range at a time. Some turtles have two home ranges. One of these turtles was followed with a trailer for 161 days in 1946 and 1947. Trips outside the home range are made by

    Full Text Available One of the most important problems involving treatments with antibiotics against Aeromonas hydrophila isolated from fishes is that antibiotic resistance develops readily. The antimicrobial activity of chemotherapeutants in isolates from pacu Piaractus mesopotamicus (Holmberg, 1887 and tilapia Oreochromis niloticus (Linnaeus, 1758 was tested by the Kirby-Bauer disk method, over Mueller-Hinton surface agar previously inoculated with 100 µL of bacterial suspensions. After regular incubation, isolates from tilapia and pacu were uniformly resistant to amoxicillin, ampicillin, lincomycin, novobiocin, oxacillin, penicillin, and trimetoprim+sulfametoxazole. The A. hydrophila type strain presented resistance to the same antimicrobial substances and also against rifampicin; the bacterial isolate from pacu were the only strain resistant to tetracyclin. Isolates from both pacu and tilapia had intermediate reaction with erytromycin. The use of drugs in commercial fish farms in Brazil can favor the development of resistant bacterial strains in native fish species as already observed for exotic species, commercially produced for longer time.Um dos maiores problemas envolvendo o tratamento com antibióticos contra Aeromonas hydrophila isolada de peixes confinados é a rápida resistência ao antibiótico desenvolvida pela bactéria.

    Chironomid midges (Diptera; Chironomidae) are found in various environments from the high Arctic to the Antarctic, including temperate and tropical regions. In many freshwater habitats, members of this family are among the most abundant invertebrates. In the present study, the genome sizes of 25 chironomid species were determined by flow cytometry and the resulting C-values ranged from 0.07 to 0.20 pg DNA (i.e. from about 68 to 195 Mbp). These genome sizes were uniformly very small and included, to our knowledge, the smallest genome sizes recorded to date among insects. Small proportion of transposable elements and short intron sizes were suggested to contribute to the reduction of genome sizes in chironomids. We discuss about the possible developmental and physiological advantages of having a small genome size and about putative implications for the ecological success of the family Chironomidae.

  13. Invasion Biology of Aedes japonicus japonicus (Diptera: Culicidae)

    2014-01-01

    Aedes japonicus japonicus (Theobald) (Diptera: Culicidae) has recently expanded beyond its native range of Japan and Korea into large parts of North America and Central Europe. Population genetic studies begun immediately after the species was detected in North America revealed genetically distinct introductions that subsequently merged, likely contributing to the successful expansion. Interactions, particularly in the larval stage, with other known disease vectors give this invasive subspecies the potential to influence local disease dynamics. Its successful invasion likely does not involve superior direct competitive abilities, but it is associated with the use of diverse larval habitats and a cold tolerance that allows an expanded seasonal activity range in temperate climates. We predict a continued but slower expansion of Ae. j. japonicus in North America and a continued rapid expansion into other areas as this mosquito will eventually be considered a permanent resident of much of North America, Europe, Asia, and parts of Hawaii.

In addition, human bronchus epithelial cell line BEAS-2B (normal cell was selected for comparison. A high-performance liquid chromatography (HPLC method was developed to separate and quantify the various curcuminoids in C. longa extract, including curcumin (1,714.5 µg/mL, demethoxycurcumin (1,147.4 µg/mL, and bisdemethoxycurcumin (190.2 µg/mL. A high-stability nanoemulsion composed of Tween 80, water, and curcuminoid extract was prepared, with mean particle size being 12.6 nm. The cell cycle was retarded at G2/M for both the curcuminoid extract and nanoemulsion treatments; however, the inhibition pathway may be different. H460 cells were more susceptible to apoptosis than A549 cells for both curcuminoid extract and nanoemulsion treatments. Growth of BEAS-2B remained unaffected for both the curcuminoid extract and nanoemulsion treatments, with a concentration range from 1 to 4 µg/mL. Also, the activities of caspase-3, caspase-8, and caspase-9 followed a dose-dependent increase for both A549 and H460 cells for both the treatments, accompanied by a dose-dependent increase in cytochrome C expression and a dose-dependent decrease in CDK1 expression. Interestingly, a dose-dependent increase in cyclin B expression was shown for A549 cells for both the treatments, while a reversed trend was found for H460 cells. Both mitochondria and death receptor pathways may be responsible for apoptosis of both A549 and H460 cells.Keywords: curcuminoid extract, curcuminoid nanoemulsion, Curcuma longa Linnaeus, lung cancer cell, cell cycle, apoptosis mechanism

    Full Text Available Variation in the number of chromosomes was revealed in 61 samples of Cimex lectularius Linnaeus, 1758 from the Czech Republic and other European countries, hosted on Myotis Kaup, 1829 (4 and Homo sapiens Linnaeus, 1758 (57. The karyotype of all the specimens of C. lectularius analysed contained 26 autosomes and a varying number of the sex chromosomes. The number of sex chromosomes showed extensive variation, and up to 20 fragments were recorded. Altogether, 12 distinct karyotypes were distinguished. The male karyotypes consisted of 29, 30, 31, 32, 33, 34, 35, 36, 37, 40, 42 and 47 chromosomes. The females usually exhibited the number of chromosomes which was complementary to the number established in the males from the same sample. However, 11 polymorphic samples were revealed in which the karyotypes of females and males were not complementary each other. The complement with 2n = 26+X1X2Y was found in 44% of the specimens and 57,4% samples of bed bugs studied. The karyotypes with higher chromosome numbers as well as individuals with chromosomal mosaics were usually found within the samples exhibiting particularly extensive variation between individuals, and such complements were not found within samples contaning a few or single specimen. The occurrence of chromosomal mosaics with the karyotype constitution varying between cells of single individual was observed in five specimens (4.3% from five samples. We assume that polymorphism caused by fragmentation of the X chromosome may result in meiotic problems and non-disjunction can produce unbalanced gametes and result in lowered fitness of individuals carrying higher numbers of the X chromosome fragments. This effect should be apparently enhanced with the increasing number of the fragments and this may be the reason for the observed distribution pattern of individual karyotypes in the studied samples and the rarity of individuals with extremely high chromosome numbers.

Gastropods' activity and ecosystem engineering preformed at bare and A. marina planted cells and 3 sewage conditions (0, 20 and 60%) were determined. Survival rates were higher than 70% in all treatments. Growth rate decreased significantly with increasing sewage concentrations (mainly at unplanted conditions) and longer immersion periods. A complete shift (from immersion to emersion periods) and a significant decrease in mobility and consequently its engineer potential, due to sewage contamination, lead to a 3-4 fold decrease in the amount of sediment disturbed. Sewage contamination, primary producers' abundance and environmental conditions may have influenced the gastropods survival, growth and its ecosystem engineering potential. - Terebralia palustris high ecosystem engineering potential in constructed mangrove wetlands.

    This study evaluated the insecticidal activity of garlic, Allium sativum Linnaeus (Amaryllidaceae) essential oil and their principal constituents on Tenebrio molitor. Garlic essential oil, diallyl disulfide, and diallyl sulfide oil were used to compare the lethal and repellent effects on larvae, pupae and adults of T. molitor. Six concentrations of garlic essential oil and their principal constituents were topically applied onto larvae, pupae and adults of this insect. Repellent effect and respiration rate of each constituent was evaluated. The chemical composition of garlic essential oil was also determined and primary compounds were dimethyl trisulfide (19.86%), diallyl disulfide (18.62%), diallyl sulfide (12.67%), diallyl tetrasulfide (11.34%), and 3-vinyl-[4H]-1,2-dithiin (10.11%). Garlic essential oil was toxic to T. molitor larva, followed by pupa and adult. In toxic compounds, diallyl disulfide was the most toxic than diallyl sulfide for pupa > larva > adult respectively and showing lethal effects at different time points. Garlic essential oil, diallyl disulfide and diallyl sulfide induced symptoms of intoxication and necrosis in larva, pupa, and adult of T. molitor between 20–40 h after exposure. Garlic essential oil and their compounds caused lethal and sublethal effects on T. molitor and, therefore, have the potential for pest control. PMID:28425475

    Wild animals may play an important role in the transmission and maintenance of Toxoplasma gondii in the environment. The purpose of the present study was to isolate and genotype T. gondii from a free-ranging crab-eating fox (Cerdocyon thous-Linnaeus, 1766). A crab-eating fox in critical health condition was attended in a veterinary hospital in Recife, Pernambuco State, Brazil. The animal died despite emergency treatment. The brain was collected aseptically and destined for mouse bioassay. One isolate of T. gondii was obtained, and Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) was used to assess genetic variability at 11 markers (SAG1, SAG2, altSAG2, SAG3, BTUB, GRA6, c228, c292, L358, PK1 and APICO). A murine model was used to assess the virulence of the isolate. Using the PCR-RFLP, genotype ToxoDB #13 was identified, which is considered an atypical strain. The isolate was classified as avirulent in the murine model. This is the first study to report T. gondii infection in the crab-eating fox. Copyright © 2017 Elsevier B.V. All rights reserved.

We trapped gold tegus in Broward and Miami-Dade counties, Florida, USA. In Miami-Dade County, collection occurred from 2008 through 2016. We combined new trapping records with previous literature records. Ten gold tegus of both sexes and multiple size classes over a nine year period indicate a reproducing population in Miami-Dade County. Tupinambis teguixin is the sixth established non-native teiid species in Florida. Additionally, we report Tupinambis teguixin from Sarasota and Lee counties, Florida, USA. Determining population status in those counties requires further study. It is critical to differentiate this species fromSalvator merianae during removal efforts. The possibility of eradicating Tupinambis teguixin exists if proper identification enables reliable monitoring of the populations.

    We used two common correlative species-distribution models to predict suitable habitat of invasive red lionfish Pterois volitans (Linnaeus, 1758) in the western Atlantic and eastern Pacific Oceans. The Generalized Linear Model (GLM) and the Maximum Entropy (Maxent) model were applied using the Software for Assisted Habitat Modeling. We compared models developed using native occurrences, using non-native occurrences, and using both native and non-native occurrences. Models were trained using occurrence data collected before 2010 and evaluated with occurrence data collected from the invaded range during or after 2010. We considered a total of 22 marine environmental variables. Models built with non-native only or both native and non-native occurrence data outperformed those that used only native occurrences. Evaluation metrics based on the independent test data were highest for models that used both native and non-native occurrences. Bathymetry was the strongest environmental predictor for all models and showed increasing suitability as ocean floor depth decreased, with salinity ranking the second strongest predictor for models that used native and both native and non-native occurrences, indicating low habitat suitability for salinities lionfish could continue to invade southern latitudes in the western Atlantic Ocean and may establish localized populations in the eastern Pacific Ocean. We reiterate the importance in the choice of the training data source (native, non-native, or native/non-native) used to develop correlative species distribution models for invasive species.

    Laevistrombus canarium Linnaeus, 1758 is one of the important edible sea snail within the western Johor Straits, Malaysia. In this study, the impact of temperature on oxygen consumption (MO2) of L. canarium based on their ontogenetic changes (juvenile and adult) was measured in the laboratory condition at 22.0, 26.0, 30.0 and 34.0°C. Measurement of MO2 were taken every 1 s for 60 min on 4.20 - 34.00 g dog conch using respirometry chamber. All experiments were carried out in static conditions in five replicates with one snail per chambers. The results of oxygen consumption showed that juvenile dog conch respired at the rate of 0.163 ml h-1 and adult respired at the rate of 0.119 ml h-1. Consequently, the oxygen consumption in juvenile and adult dog conch was expressed as a total energy spends. The results indicates that total energy spend for oxygen consumed (ml h-1) of L. canarium at different temperature regimes (22.0 to 34.0°C) slightly increased over time period (0.63 ± 0.12 to 3.24 ± 0.05 J h-1) respectively. This finding of the present study suggested L. canarium is well adapted for life in high temperature environment.

  13. Size differences in the Dufour gland of Apis mellifera Linnaeus (Hymenoptera, Apidae between and within the female castes

    Full Text Available The Dufour gland is found closely associated with the sting apparatus of all hymenopteran females, playing multiple roles among bees. In Apis mellifera Linnaeus, 1758 the gland is connected to the dorsal vaginal wall and, in queens, it produces egg-marking pheromones. In workers the function of this gland is unknown, except by its capacity to mimic the queen secretion in egg-laying workers. In an attempt to understand the development and to substantiate the present knowledge about the Dufour gland in A. mellifera, a morphometric study of the gland between and within the female castes was made. Glands of workers and queens with different ages and life stages were dissected and measured with an ocular micrometer adapted to a stereoscope. The results showed that the Dufour gland is larger in queens than in workers, and that among workers, the gland is larger in egg-laying and foragers than it is in newly emerged and nurse workers. The larger size of the gland in egg-laying queens and workers is in accordance with its role in reproduction. In forager workers the larger size of the gland suggest that, as happens in some species of bees, the gland may participate in pheromone production for nest-mate or nest-entrance recognition.

    Full Text Available Human activities have been diminishing greater rhea Rhea americana (Linnaeus, 1758 populations throughout their natural distribution. The reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintroduced were killed by predators. Captive-born animals that have been isolated from predators for many generations can lose their predator recognition abilities. To enhance the survival rates of the reintroduced animals, researchers are now using antipredator training techniques. We studied the response of 15 zoo-borne greater rheas to antipredator training. The animals were divided into three groups: two test groups and one control group. We ran 15 antipredator tests and four control testes with each group. Antipredator tests consisted of pairing a taxidermized predator model or a real predator (domestic dog with a simulation of a capture procedure. Control tests consisted of presenting the predator model (jaguar to the birds, after training but not associating it with an aversive event and recording behavioural responses. All tests were video-recorded and analysed a posteriori. Results showed that the trained rheas responded appropriately to the predators, becoming more vigilant and that there was considerable individual differences in response to antipredator training. The results demonstrated that antipredator training is effective and therefore an invaluable tool for reintroduction projects involving greater rheas. Furthermore, the methods employed in this research project should be applicable to other species of flightless birds.As atividades humanas têm diminuído as populações de emas Rhea americana (Linnaeus, 1758 por toda sua área de distribuição.

The relationship LNxCW was expressed by the equation LN = 284.1CW1.5º¹ (N = 58; R² = 0.74; p < 0.01, that showed a positive correlation between the variables. Most part of ovigerous females (89.7% showed their hatching during the nightly period. A negative correlation between HR and CW was observed in these animals (p < 0.05, probably due to reduction of spermatophores in the seminal receptacle (multiparous females or due to senility in the females with large size. The biological studies of U. cordatus are very important for practices adoption that preserve and make the rational use of this recourse in Brazilian's mangrove forests.

    Full Text Available In recent years, there has been an increasing number of studies on carrion fly communities due to their medical importance and as a consequence of the large number of studies on forensic entomology. Surprisingly few studies have adressed with the asynantropic flies of the Amazon, and none were done in Colombia. A faunistic study of asynantropic flies of the families Calliphoridae, Sarcophagidae, Muscidae and Fannidae in three different landscapes of the Colombian Amazon is presented, trapping effectiveness is assessed, and the first record of Mesembrinella batesi (Aldrich, 1922 and Fannia femoralis (Stein, 1897 from Colombia is reported.Apesar de existir uma quantidade considerável de estudos sobre dípteros decompositores devido a sua importância medica e ao avanço da entomologia forense, poucos dizem respeito as moscas asinantrópicas na Amazônia e nada foi feito na Colômbia. No presente trabalho é feito um estudo faunístico sobre moscas, principalmente das famílias Calliphoridae, Sarcophagidae, Muscidae e Fanniidae em três diferentes paisagens da Amazônia Colombiana, além do primeiro registro das espécies Mesembrinella batesi (Aldrich, 1922 e Fannia femoralis (Stein, 1897 para Colômbia e avaliação da amostragem utilizada.

    In the present study novel histopathological approach, using fish intestine as a sensitive bioindicator organ of pollution impact in the freshwater ecosystem, was proposed. Histopathological alterations were compared between native brown trout (Salmo trutta Linnaeus, 1758) from the reference (Krka River spring) and pollution impacted location (influence of technological/municipal wastewaters and agricultural runoff near the Town of Knin) of the karst Krka River in Croatia. In brown trout from both locations, severe parasitic infestation with acanthocephalan species Dentitruncus trutae was found, enabling evaluation of acanthocephalan infestation histopathology, which indicated parasite tissue reaction in a form of inflammatory, necrotic and hyperplastic response that extended throughout lamina epithelialis mucosae, lamina propria, and lamina muscularis mucosae. New semi-quantitative histological approach was proposed in order to foresee alterations classified in three reaction patterns: control tissue appearance, moderate (progressive) tissue impairment and severe (regressive and inflammatory) tissue damage. The most frequent progressive alteration was hyperplasia of epithelium on the reference site, whereas the most frequent regressive alterations were atrophy and necrosis seen on the polluted site. Furthermore, histopathological approach was combined with micromorphological and macromorphological assessment as an additional indicator of pollution impact. Among 15 observed intestinal measures, two biomarkers of intestinal tissue damage were indicated as significant, height of supranuclear space (hSN) and number of mucous cells over 100 μm fold distance of intestinal mucosa (nM), which measures were significantly lower in fish from polluted area compared to the reference site. Obtained results indicated that combined histological and morphological approach on fish intestinal tissue might be used as a valuable biological tool for assessing pollution impact on

    Full Text Available Purpose. To analyze the dynamics of pike (Esox luceus Linnaeus, 1758 age structure of the Dnieper lower reaches in conditions of the modification of fishing pressure. Methodology. An analysis of fishing situation has been performed based on data of official fishery statistics. Fish sampling was done at control-observation posts of the Institute of Fisheries of the NAAS of Ukraine and directly in the fishery. Juvenile fish yield was determined using a complex of fry fishing gears using a stationary net-station. Field and cameral processing of the material was performed using generally accepted methods. Findings. A retrospective analysis of the situation in the Dnieper-Bug lower reach system clearly indicates on the presence of continuous tendency of catch decline of representative of native fish fauna – pike. With relatively uniform indices of the “yield” of its juveniles before Dnieper flow impoundment and in conditions of present time, its commercial catches significantly dropped. The dynamics of pike current age structure indicates on an increase of relative density of age groups, which form the recruitment of the commercial portion of the population (1-1+ and a decrease of importance of the component of the right side of age series. A discrepancy between the observed changes of the age group and commercial harvest quantities indicates on increased human pressure on this species. Originality. For the first, we analyzed the dynamics of fish juvenile “yield” and age structure of pike commercial stock of the Dnieper lower reaches in the river flow transformation process. Practical value. A decrease of the ichthyomass of piscivorous fishes in the Dnieper lower reaches results in changes of fish populations of littoral biotopes towards the prevalence of the dominance of coarse species that lead to a deterioration of forage availability for a number of valuable commercial species. An increase of the number of pike can regulate the strain

    Full Text Available This study presents additional genetic data on piranha (Serrasalmus rhombeus Linnaeus, 1766 complex previously diagnosed due to the presence of distinct cytotypes 2n = 58 and 2n = 60. Three esterase-D enzyme loci (Est-D1, Est-D2 and Est-D3 were examined and complemented with chromosomal data from 66 piranha specimens collected from Lake Catalão. For all specimens the Est-D1 and Est-D2 loci were monomorphic. In contrast, the Est-D3 locus was polymorphic with genotypes and alleles being differentially distributed in the previously described cytotypes and served as the basis for detecting a new cytotype (2n = 60 B. In cytotype 2n = 58 the Est-D3 locus was also polymorphic and presented Mendelian allelic segregation with four genotypes (Est-D3(11, Est-D3(12, Est-D3(22 and Est-D3(33 out of six theoretically possible genotypes, presumably encoded by alleles Est-D3¹ (frequency = 0.237, EsT-D3² (0.710 and Est-D3³ (0.053. A Chi-squared (chi2 test for Hardy-Weinberg equilibrium was applied to the Est-D3 locus and revealed a genetic unbalance in cytotype 2n = 58, indicating the probable existence in the surveyed area of different stocks for that karyotypic structure. A silent null allele (Est-D3(0 with a high frequency (0.959 occurred exclusively in the 2n = 60 cytotype. On the other hand, the new cytotype 2n = 60 B described here for the first time was monomorphic for the presumably fixed Est-D3³ allele. The data as a whole should contribute to the better understanding the rhombeus complex taxonomic status definition in the Central Amazon.

  7. The genome structure of Arachis hypogaea (Linnaeus, 1753 and an induced Arachis allotetraploid revealed by molecular cytogenetics

    Full Text Available Peanut, Arachis hypogaea (Linnaeus, 1753 is an allotetraploid cultivated plant with two subgenomes derived from the hybridization between two diploid wild species, A. duranensis (Krapovickas & W. C. Gregory, 1994 and A. ipaensis (Krapovickas & W. C. Gregory, 1994, followed by spontaneous chromosomal duplication. To understand genome changes following polyploidy, the chromosomes of A. hypogaea, IpaDur1, an induced allotetraploid (A. ipaensis × A. duranensis4x and the diploid progenitor species were cytogenetically compared. The karyotypes of the allotetraploids share the number and general morphology of chromosomes; DAPI+ bands pattern and number of 5S rDNA loci. However, one 5S rDNA locus presents a heteromorphic FISH signal in both allotetraploids, relative to corresponding progenitor. Whilst for A. hypogaea the number of 45S rDNA loci was equivalent to the sum of those present in the diploid species, in IpaDur1, two loci have not been detected. Overall distribution of repetitive DNA sequences was similar in both allotetraploids, although A. hypogaea had additional CMA3+ bands and few slight differences in the LTR-retrotransposons distribution compared to IpaDur1. GISH showed that the chromosomes of both allotetraploids had preferential hybridization to their corresponding diploid genomes. Nevertheless, at least one pair of IpaDur1 chromosomes had a clear mosaic hybridization pattern indicating recombination between the subgenomes, clear evidence that the genome of IpaDur1 shows some instability comparing to the genome of A. hypogaea that shows no mosaic of subgenomes, although both allotetraploids derive from the same progenitor species. For some reasons, the chromosome structure of A. hypogaea is inherently more stable, or, it has been at least, partially stabilized through genetic changes and selection.

    As conspicuous modular components of benthic marine habitats, gorgonian (sea fan) octocorals have perplexed taxonomists for centuries through their shear diversity, particularly throughout the Indo-Pacific. Phenotypic incongruence within and between seemingly unitary lineages across contrasting environments can provide the raw material to investigate processes of disruptive selection. Two distinct phenotypes of the Isidid Isis hippurisLinnaeus, 1758 partition between differing reef environments: long-branched bushy colonies on degraded reefs, and short-branched multi/planar colonies on healthy reefs within the Wakatobi Marine National Park (WMNP), Indonesia. Multivariate analyses reveal phenotypic traits between morphotypes were likely integrated primarily at the colony level with increased polyp density and consistently smaller sclerite dimensions at the degraded site. Sediment load and turbidity, hence light availability, primarily influenced phenotypic differences between the two sites. This distinct morphological dissimilarity between the two sites is a reliable indicator of reef health; selection primarily acting on colony morphology, porosity through branching structure, as well as sclerite diversity and size. ITS2 sequence and predicted RNA secondary structure further revealed intraspecific variation between I. hippuris morphotypes relative to such environments (ΦST = 0.7683, P < 0.001). This evidence suggests-but does not confirm-that I. hippuris morphotypes within the WMNP are two separate species; however, to what extent and taxonomic assignment requires further investigation across its full geographic distribution. Incongruence between colonies present in the WMNP with tenuously described Isis alternatives (Isis reticulataNutting, 1910, Isis minorbrachyblastaZou, Huang & Wang, 1991), questions the validity of such assignments. Furthermore, phylogenetic analyses confirm early taxonomic suggestion that the characteristic jointed axis of the Isididae is in

    Gynogenetic and androgenetic brown trout (Salmo trutta Linnaeus 1758) haploids (Hs) and doubled haploids (DHs) were produced in the present research. Haploid development was induced by radiation-induced genetic inactivation of spermatozoa (gynogenesis) or eggs (androgenesis) before insemination. To provide DHs, gynogenetic and androgenetic haploid zygotes were subjected to the high pressure shock to suppress the first mitotic cleavage. Among haploids, gynogenetic embryos were showing lower mortality when compared to the androgenetic embryos; however, most of them die before the first feeding stage. Gynogenetic doubled haploids provided in the course of the brown trout eggs activation performed by homologous and heterologous sperm (rainbow trout) were developing equally showing hatching rates of 14.76 ± 2.4% and 16.14 ± 2.90% and the survival rates at the first feeding stage of 10.48 ± 3.48% and 12.78 ± 2.18%, respectively. Significantly, lower survival rate was observed among androgenetic progenies from the diploid groups with only few specimens that survived to the first feeding stage. Cytogenetic survey showed that among embryos from the diploid variants of the research, only gynogenetic individuals possessed doubled sets of chromosomes. Thus, it is reasonable to assume that radiation employed for the genetic inactivation of the brown trout eggs misaligned mechanism responsible for the cell divisions and might have delayed or even arrested the first mitotic cleavage in the androgenetic brown trout zygotes. Moreover, protocol for the radiation-induced inactivation of the paternal and maternal genome should be adjusted as some of the cytogenetically surveyed gynogenetic and androgenetic embryos exhibited fragments of the irradiated chromosomes. © 2015 Blackwell Verlag GmbH.

    Experiments with 134 Cs and the fish Tinca tinca Linnaeus (fam. Cyprinidae), as a part of a more extensive work, concerning a simplified freshwater trophic chain using water from Fratel dam, (at Tejo River), were undertaken. Direct uptake from water, during a period of about 30 days, leads to a kinetics expressed by the power function: CF (t) = 0.58 t 0.781 (t in days), the concentration factor (CF) referred to wet weight. Retention study, showed the existence of two biological half-lives, Tb 1 = 7 days and Tb 2 = 87 days, which might concern respectively, the 134 Cs desorption from the transit organs and the loss of the assimilated isotope from the storage organs. In the accumulation through the food chain, using planktonic crustacean Daphnia magna Straus (Cladocera) as prey, a transfer factor (TF) related to wet weight of both fish and prey, is estimated through the power function: TF (t) = 0.022 t 0.578 (t in days). Finally, the retention study following the food pathway contamination, stresses the existence of one long term component, with half-life Tb = 61 days. The transfer factor kinetics seems to point out to a rather slow process, leading to lower 134 Cs concentration values, than the contamination through the water. The loss of the assimilated 134 Cs, uptaken through both pathways, water or food, is a slow process. The longer biological half-life is very important in Radiological Protection, once it may be attributed to the radionuclide loss from the muscular mass. (author)

    The essential oil (EO) of Piper aduncum Linnaeus, known as 'sireh lada' to locals Malaysian, has the potential to be used as an alternative to synthetic insect repellents such as N,N-diethyl-meta-toluamide. However, the EO's efficacy as a repellent decreases after application due to the high volatility of its active ingredients. A number of studies have showed that optimizing the formulation of plant-based EOs can improve their efficacy as repellents. The present study sought to evaluate the effectiveness of 10% P. aduncum EO in ethanol and in three different semisolid formulations: ointment, cream and gel. These formulations were tested on Aedes aegypti under laboratory conditions. Each formulation was applied to the subject's hands, which were then inserted into a cage containing 25 nulliparous A. aegypti. The number of mosquitoes landing on or biting each subject's hand was recorded, and the repellency percentage, landing/biting percentage and protection time for each of the formulations were compared. There were no statistically significant differences between the semisolid EO formulations with regards to the repellency percentage and the landing/biting percentage at 4 h post-application. All three semisolid EO formulations were able to repel >65% of the A. aegypti at 4 h post-application. The EO ointment formulation provided a protection time (182.5 ± 16.01 min) that was statistically significantly longer than that associated with the EO gel formulation (97.5 ± 14.93 min). Meanwhile, the EO cream formulation provided a protection time of 162.5 ± 6.29 min. As the EO cream and ointment formulations displayed better repellent properties than the EO gel formulation, they appear to be the most promising P. aduncum EO formulations to be developed and commercialized as alternatives to synthetic repellents.

  14. Spatially explicit genetic structure in the freshwater sponge Ephydatia fluviatilis (Linnaeus, 1759 within the framework of the monopolisation hypothesis

    Full Text Available An apparent paradox is known for crustaceans, rotifers and bryozoans living in inland small water bodies: a potential for wide distribution due to the presence of resting stages is coupled with marked genetic differences between nearby water bodies, with enclave distributions masking clear phylogeographic patterns. According to the monopolisation hypothesis, this is due to the accumulation of resting stages, monopolising each water body. Freshwater sponges could represent a useful system to assess the generality of the mo- nopolisation hypothesis: these organisms i live in the same habitats as crustaceans, rotifers and bryozoans, ii produce resting stages that can accumulate, and iii have indeed a wide distribution. Currently, no studies on spatially explicit genetic differentiation on fresh- water sponges are available. The aim of the present study is to provide additional empirical evidence in support of the generality of the scenario for small aquatic animals with resting stages by analysing genetic diversity at different spatial scales for an additional model system, the freshwater sponge ephydatia fluviatilis (Linnaeus, 1759. We expected that system genetic variability would follow enclave distributions, no clear phylogeographical patterns would be present, and nearby unconnected water bodies would show markedly different populations for this new model too. We analysed the ribosomal internal transcribed spacer regions 5.8S-ITS2-28S, the D3 domain of 28S subunit, the mitochondrial Cytochrome c Oxidase I (COI and ten specific microsatellite markers of nine Italian and one Hungarian populations. Mitochondrial and nuclear sequences showed no or very low genetic polymorphism, whereas high levels of differentiation among populations and a significant polymorphism were observed using microsatellites. Microsatellite loci also showed a high proportion of private alleles for each population and an overall correlation between geographic and genetic

    The objectives of this study were to explore the inhibition mechanism of lung cancer cells A549 and H460 by curcuminoid extracts and nanoemulsions prepared from Curcuma longa Linnaeus. In addition, human bronchus epithelial cell line BEAS-2B (normal cell) was selected for comparison. A high-performance liquid chromatography (HPLC) method was developed to separate and quantify the various curcuminoids in C. longa extract, including curcumin (1,714.5 μg/mL), demethoxycurcumin (1,147.4 μg/mL), and bisdemethoxycurcumin (190.2 μg/mL). A high-stability nanoemulsion composed of Tween 80, water, and curcuminoid extract was prepared, with mean particle size being 12.6 nm. The cell cycle was retarded at G2/M for both the curcuminoid extract and nanoemulsion treatments; however, the inhibition pathway may be different. H460 cells were more susceptible to apoptosis than A549 cells for both curcuminoid extract and nanoemulsion treatments. Growth of BEAS-2B remained unaffected for both the curcuminoid extract and nanoemulsion treatments, with a concentration range from 1 to 4 μg/mL. Also, the activities of caspase-3, caspase-8, and caspase-9 followed a dose-dependent increase for both A549 and H460 cells for both the treatments, accompanied by a dose-dependent increase in cytochrome C expression and a dose-dependent decrease in CDK1 expression. Interestingly, a dose-dependent increase in cyclin B expression was shown for A549 cells for both the treatments, while a reversed trend was found for H460 cells. Both mitochondria and death receptor pathways may be responsible for apoptosis of both A549 and H460 cells.

    Full Text Available The aim of this paper was to analyze the distribution of chironomids (Diptera, Chironomidae, and determine their substrate preferences, from two hydrosystems located in northeastern Algeria: the Kebir-East and the Seybouse wadis. Sixty-five species were recorded in 49 sampling sites distributed along the main courses of the two hydrographic nets and their tributaries. The majority of taxa comprised cosmopolitan species widely distributed along these two hydrosystems. Cricotopus (Cricotopus bicinctus showed the highest abundance and frequency of occurrence (29.52% and was widespread in almost all the sampling sites. Species richness ranged from 4 to 23, Shannon diversity between 0.15 and 0.90, Evenness from 0.23 to 1. A cluster analysis was carried out to represent the different groups of sites sharing similar species composition. Agglomerative cluster analysis grouped the sampling sites into four clusters according to the community data. An Indval analysis was then carried out to detect indicator species for each group of the sampling sites. Cricotopus (Isocladius sylvestris was indicator of the first group of the sampling sites. Orthocladius pedestris, Rheocricotopus chalybeatus and C. bicinctus were indicators of the second group, and Polypedilum cultellatum of the third group. The fourth group was not characterized by any species. Indval analysis allowed also to determine species preferences for substrate size: Corynoneura scutellata and Dicrotendipes nervosus emphasized a preference to fine gravel, and Glyptotendipes pallens to fine sand.

    Anastrepha grandis (Macquart) (Diptera: Tephritidae) is one of the main pests of cucurbits in Brazil. Losses occur due to the damage caused to the fruits and the embargo on exports, as A. grandis is considered a quarantine pest in countries that import Brazilian cucurbits. This study aimed to evaluate the development of A. grandis in hosts of the Cucurbitaceae family. The hosts used were stem squash (Cucurbita pepo L.), squash (Cucurbita moschata Duchesne), chayote [Sechium edule (Jacq.) Swartz], mini watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai], Spanish melon (Cucumis melo L.), hybrid squash "Tetsukabuto" (C. moschata×Cucurbita maxima Duchesne), and salad cucumber (Cucumis sativus L.). We evaluated the viability and duration of egg-to-pupa period, pupal weight, sex ratio, and average number of pupae per fruit under controlled conditions of temperature, relative humidity, and photophase. The preoviposition and oviposition periods, fecundity, fertility, and longevity of females were determined for adults. Hosts of the genus Cucurbita provided a better development of A. grandis in comparison with other hosts, and presented a greater number of insects on fruit as well as higher infestation rate. Fecundity and longevity were also higher for females that developed in hosts of the genus Cucurbita, although values of these biological parameters varied between stem squash, squash, hybrid squash "Tetsukabuto." © The Authors 2015.

    Aedes aegypti, the principal vector of yellow fever and dengue fever, is responsible for more than 30,000 deaths annually. Compounds such as carbon dioxide, amino acids, fatty acids and other volatile organic compounds (VOCs) have been widely studied for their role in attracting Ae. aegypti to hosts. Many VOCs from humans are produced by associated skin microbiota. Staphyloccocus epidermidis, although not the most abundant bacteria according to surveys of relative 16S ribosomal RNA abundance, commonly occurs on human skin. Bacteria demonstrate population level decision-making through quorum sensing. Many quorum sensing molecules, such as indole, volatilize and become part of the host odor plum. To date, no one has directly demonstrated the link between quorum sensing (i.e., decision-making) by bacteria associated with a host as a factor regulating arthropod vector attraction. This study examined this specific question with regards to S. epidermidis and Ae. aegypti. Pairwise tests were conducted to examine the response of female Ae. aegypti to combinations of tryptic soy broth (TSB) and S. epidermidis wildtype and agr- strains. The agr gene expresses an accessory gene regulator for quorum sensing; therefore, removing this gene inhibits quorum sensing of the bacteria. Differential attractiveness of mosquitoes to the wildtype and agr- strains was observed. Both wildtype and the agr- strain of S. epidermidis with TSB were marginally more attractive to Ae. aegypti than the TSB alone. Most interestingly, the blood-feeder treated with wildtype S. epidermidis/TSB attracted 74% of Ae. aegypti compared to the agr- strain of S. epidermidis/TSB (P ≤ 0.0001). This study is the first to suggest a role for interkingdom communication between host symbiotic bacteria and mosquitoes. This may have implications for mosquito decision-making with regards to host detection, location and acceptance. We speculate that mosquitoes "eavesdrop" on the chemical discussions occurring between host-associated microbes to determine suitability for blood feeding. We believe these data suggest that manipulating quorum sensing by bacteria could serve as a novel approach for reducing mosquito attraction to hosts, or possibly enhancing the trapping of adults at favored oviposition sites.

    Biological transmission of arboviruses to a vertebrate host occurs when virions are expelled along with saliva during blood feeding by a hematophagous arthropod. We undertook experiments to determine whether mosquitoes expectorate flaviviruses in their saliva while sugar feeding. Batches of Culex annulirostris Skuse and Culex gelidus Theobald (Diptera: Culicidae) were orally infected with Japanese encephalitis (family Flaviviridae, genus Flavivirus, JEV), Kunjin (family Flaviviridae, genus Flavivirus, KUNV; a subtype of West Nile virus), and Murray Valley encephalitis (family Flaviviridae, genus Flavivirus, MVEV) viruses. After a 7-d extrinsic incubation, these mosquitoes were offered sucrose meals via cotton pledgets, which were removed daily and processed for viral RNA by using real-time TaqMan reverse transcriptase-polymerase chain reaction (RT-PCR) assays. JEV, MVEV, and KUNV RNA was detected in all pledgets removed from batches of Cx. gelidus on days 7-14 postexposure. In contrast, detection rates were variable for Cx. annulirostris, with KUNV detected in 0.3 M sucrose pledgets on all days postexposure, and JEV and MVEV detected on 57 and 50% of days postexposure, respectively. Higher concentrations of sucrose in the pledget did not increase virus detection rates. When individual JEV-infected Cx. gelidus were exposed to the sucrose pledget, 73% of mosquitoes expectorated virus with titers that were detectable by TaqMan RT-PCR. These results clearly show that flaviviruses are expectorated by infected mosquitoes during the process of sugar feeding on artificial pledgets. Potential applications of the method for arboviral bioassays and field surveillance are discussed.

    2011-11-01

    Full Text Available A canopy trap and aerial nets led to finding 8 species of Tabanidae. There was an abundance of calyptrate muscoid flies. Camel’s Hump is in the Green Mountains of western New England, USA. Discovering Diptera on Camel’s Hump involved sixteen visits over 40 years. Upwards of 23 other Diptera species are listed. Habitats on the east side and above 762 m (2500 ft elevation on Camel’s Hump differ from the west slope but the boreal forest on both sides is influenced by cloud and fog precipitation on trees. The cliffs just above the 900 m level along the east side are often overlooked, are not seen from the summit and provide access to morning sun for insects. Recent visits explored the role of polarized skylight in relation to the canopy trap, the boreal forest environment and flies found there.

  12. [Means of the formation of gonotrophic relations in blood-sucking Diptera].

    Tamarina, N A

    1987-01-01

    Gonotrophic relations in low and higher bloodsucking Diptera are fundamentally different that results from an initial type of feeding and trophic behaviour. Trophic behaviour of low dipterous hematophages and gonotrophic harmony peculiar to them can be traced from entomophagy, that is from the predatory mode of life on account of small insects. By the type of the trophic behaviour low bloodsucking Diptera are predators with a typical moment contact with the prey. More primitive is a type of gonotrophic harmony characteristic of hunters for diffusely spread prey (incomplete blood portion provides the maturation of incomplete portion of eggs). Hunting for diffusely spread prey is characteristic of entomophages too. The appearance of gregarious ruminants facilitates the possibility of repeated contacts with prey and blood satiation threshold increases. This is a higher type of gonotrophic harmony providing a maximum realization of potential fecundity. The initial saprophagy of higher Diptera is associated with another type of trophic behaviour (long contact with food substratum) that is a prerequisite for quite a different way of evolution of host-parasite relationships in higher Diptera. This leads to more close connections with the host and excludes gonotrophic harmony. Females were the first to begin the exploitation of vertebrate animals. This is connected with the peculiarities of their behaviour during egg laying such as the stay near animals for laying eggs into fresh dung. Autogeneity, nectarophagy and aphagia are homologous phenomena which reflect the loss of an animal component of food or both components at the level of non-specialized saprophagy rather than secondary loss of bloodsucking. The scheme of gonotrophic relations is given.

    2003-12-01

    Full Text Available OBJECTIVE: Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. METHODS: Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. RESULTS: A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. CONCLUSIONS: The characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.

  7. Passage of ingested Mansonella ozzardi (Spirurida: Onchocercidae) microfilariae through the midgut of Aedes aegypti (Diptera: Culicidae).

    When virus and microfilariae are ingested concurrently by a mosquito, microfilariae (mf) may penetrate the mosquito midgut and introduce virus directly into the mosquito hemocoel, allowing mosquitoes to become infectious much sooner than normal and enhancing transmission of viruses by mosquitoes. Mansonella ozzardi (Manson) is a benign filarial nematode parasite of humans in Latin America and is transmitted by black flies (Diptera: Simuliidae) and biting midges (Diptera: Ceratopogonidae). Because M. ozzardi and dengue are sympatric, we wanted to know whether M. ozzardi mf had the ability to penetrate the midgut of Aedes aegypti (L.) (Diptera: Culicidae) and thus play a potential role in the enhancement of dengue transmission. To test this, the F1 progeny from locally collected Ae. aegypti were fed on M. ozzardi-infected human males in an endemic village in northern Trinidad. Mosquitoes were dissected at various times after feeding and examined for mf in the midguts and thoraces. Microfilariae penetrated the midguts of 43% of 63 mosquitoes that ingested mf. Overall, 11% of mf penetrated the midgut by 17 h after being ingested. The intensity of midgut penetration was positively correlated to the numbers of mf ingested. Because midgut penetration is a key requirement for mf enhancement to occur, the potential exists that M. ozzardi could be involved in the enhancement of dengue virus transmission.

    Full Text Available Water ferns (Azolla spp., Azollaceae are reported for the first time as host plants for the larvae of the small China-mark moth Cataclysta lemnata (Linnaeus (Lepidoptera: Crambidae: Acentropinae in rice fields and waterways of northern Iran. Cataclysta lemnata is a semi-aquatic species that has been recorded to feed on Lemnaceae and a few other aquatic plants. However, it has not been reported before on Azolla spp. Larvae use water fern as food source and shelter and, at high population density in the laboratory, they completely wiped water fern from the water surface. Feeding was confirmed after rearing more than eight continual generations of C. lemnata on water fern in the laboratory. Adults obtained this way are darker and have darker fuscous markings in both sexes compared with specimens previously reported and the pattern remains unchanged after several generations.

    Full Text Available A study about the species of Piperaceae that are consumed by a colony of Carollia perspicillata (Linnaeus, 1758 in Parque Municipal Arthur Thomas (82,72 ha was carried out. Five available species of Piperaceae were found in the park: Piper aduncum Linnaeus, Piper amalago (Jacq. Yuncker, Piper crassinervium H.B.K., Piper gaudichaudianum Kunth and Piper sp. C. perspicillata fed on all of these species. During the spring, the most abundant item was P. amalago, but the consumption of P. aduncum was the highest. At the beginning of the summer, P. crassinervium was the most abundant and most consumed item. At the end of the summer and during the fall, P. gaudichaudianum was the most abundant and consumed item, even in May, when P. amalago was the most abundant item. During the winter, the most highly available items were P. aduncum, Piper sp. and P. amalago, and the ones that were consumed the most were Piper sp., P. gaudichaudianum and P. aduncum. The results have shown that the preferences of C. perspicillata in the park are related to the greater abundance or the higher energetic value of the available Piperaceae. The greater search for the most energetic and least abundant species, which happened in the spring and winter, is related to the energy gain, that is, the species searches for food that will provide a greater quantity of energy per unit of consumption; and the greater search for the most abundant item, which occurred in the summer and fall, is related to saving the energy used in the search for food.Estudou-se quais espécies de piperáceas são consumidas por uma colônia de Carollia perspicillata (Linnaeus, 1758 localizada do Parque Municipal Arthur Thomas (82,72ha.

    Oryza sativa Linnaeus is an important food item all around the world. Due to its huge consumption, a large amount of rice husk is generated as agrowaste which can be used for water treatment by adsorption. Its adsorption capacity further can be enhanced by chemical medication. In the present study, urea modified rice husk has been used for removing Brilliant Vital Red and Murexide form water in an efficient way. After optimizing operating conditions, isothermal and thermodynamical studies were carried out, which showed that maximum adsorption capacity of urea modified rice husk for removing Brilliant Vital Red and Murexide dyes were 28.93 and 30.74 mg.g/sup -1/. Adsorbent characterization was carried out by recording its FT-IR spectra. (author)

    Abstract. The açai palm (Euterpe oleracea Martius is a native palm tree from the Amazon region floodplains and may be indicated as the most economically profitable species of this genus. Its fruit pulp is extracted and widely consumed by the population of northern Brazil in several ways. With the expansion of the planted area many factors may affect the production and limit the cultivation, highlighting the occurrence of insect pests that cause losses in production. This report presents the first occurrence of the leafhopper Aetalion reticulatum (Linnaeus (Hemiptera: Auchenorrhyncha: Aethalionidae in E. oleracea plants. The occurrence of this insect associated with açai palms in Rio Branco, Acre, increases the list of hosts for this leafhopper in Brazil and reinforces the need for studies of population dynamics, survey of natural enemies, levels of damage and control methods in order to anticipate population outbreaks of this pest in commercial plantations of açai palms in the State.

  16. Agonistic and reproductive behaviors in males of red hybrid tilapia, Oreochromis niloticus (Linnaeus, 1758 x O. mossambicus (Peters, 1852 (Osteichthyes: Cichlidae

    Directory of Open Access Journals (Sweden)

    APT Medeiros

    Full Text Available The red hybrid tilapia, Oreochromis niloticus (Linnaeus, 1758 x O. mossambicus (Peters, 1852 is a fertile hybrid used in the semi-intensive level of fish culture in the Northeast of Brazil. It is a territorial cichlid and is highly aggressive towards conspecifics during the breeding season. The purpose of this study was to investigate and describe the aggressive behaviour displayed by the males of this hybrid in non-reproductive and reproductive contexts. Behavioural observations revealed that aggression displayed by the reproductive males of red hybrid tilapia included threatening, undulation, parallel, lateral and frontal attacks, chasing, escape and submission. Possession of a territory influenced male aggressiveness, which was more intense in their own territory than that observed in a neutral situation. The males built nests, irrespective of female presence. All the behavioural patterns were in accordance with those previously described for one parental species, the Nile tilapia, O. niloticus.

    2017-12-01

    Canine distemper virus (CDV) affects many wild and captive, nondomestic species worldwide but has not been previously reported in Xenarthra. Paucity of information on vaccination safety and efficacy presents challenges for disease prevention in captive collections. CDV infections and subsequent mortalities in five captive Linnaeus's two-toed sloths ( Choloepus didactylus) in eastern Tennessee are reported. Clinical signs included oculonasal discharge, oral ulcerations, and diarrhea, and the diagnosis was confirmed by necropsy, histopathology, immunohistochemistry, virus isolation, and polymerase chain reaction. Viral sequencing identified the strain to be consistent with a new CDV lineage currently affecting domestic dogs and wildlife in Tennessee. Seven sloths were examined and vaccinated using a recombinant CDV vaccine on days 0 and 21. Subsequent blood samples showed increased titers in 3/4 sloths. Based on the outbreak and serologic findings postvaccination without adverse effects, the authors recommend recombinant CDV vaccination in sloths exposed to known carriers of CDV.

    A new species, Castosyringophilus meropis sp. n., found in quills of feathers of the European bee-eater Merops apiaster Linnaeus (Coraciiformes: Meropidae) is described. This new species is close to C. claravis Skoracki et Glowska, 2008 and differs, in females, by the presence apunctate coxal fields (vs sparsely punctate in C. claravis) and by the lengths of setae d1 145-180 µm, f2 170-185 µm and ag3 190-215 µm (vs d1 200-220 µm, f2 230-250 µm and ag3 150-170 µm). We present a vast mite material collected from bee-eaters originated from different localities in Europe, Asia and Africa, both breeding and wintering grounds of this bird. It indicates that the whole world population of the European bee-eater is parasitised by this quill mite species.

    The male reproductive system of Dolycoris baccarum (Linnaeus 1758) is studied morphologically and histologically using both light and scanning electron microscopes (SEM). The reproductive system of the male D. baccarum consists of a pair of testis, a pair of vas deferens, a pair of seminal vesicles, accessory glands (mesadenia, ectadenia), a bulbus ejaculatorius, a pair of ectodermal sacs, and a ductus ejaculatorius. The number of testicular follicles varies from four to six. The testicular follicles have three different development zones (growth zone, maturation zone, differentiation zone). The testes are connected to the seminal vesicles by the vas deferens. Vas deferens and seminal vesicles, which are fine-long and cylindrical. The seminal vesicle is connected with bulbus ejaculatorius which is balloon-shaped and surrounded with accessory glands. The bulbus ejaculatorius is continuous with ductus ejaculatorius which connected to the aedeagus. Copyright © 2012 Elsevier Ltd. All rights reserved.

  20. Differential Diptera succession patterns onto partially burned and unburned pig carrion in southeastern Brazil

    Directory of Open Access Journals (Sweden)

    J Oliveira-Costa

    Full Text Available In the present contribution we compared the entomological succession pattern of a burned carcass with that of an unburned one. For that, we used domestic pig carcasses and focused on Calliphoridae, Muscidae and Sarcophagidae flies, because they are the ones most commonly used in Postmortem Interval estimates. Adult and immature flies were collected daily. A total of 27 species and 2,498 specimens were collected, 1,295 specimens of 26 species from the partially burned carcass and 1,203 specimens of 22 species from the control carcass (unburned. The species composition in the two samples differed, and the results of the similarity measures were 0.875 by Sorensen and 0.756 by Bray-Curtis index. The results obtained for both carcasses also differ with respect to the decomposition process, indicating that the post mortem interval would be underestimated if the entomological succession pattern observed for a carcass under normal conditions was applied to a carbonized carcass.

    Rapid and efficient DNA-based tools are recommended for the evaluation of the insect biodiversity of high-altitude streams. In the present study, focused principally on larvae of the genus Diamesa Meigen 1835 (Diptera: Chironomidae), the congruence between morphological/molecular delimitation of species as well as performances in taxonomic assignments were evaluated. A fragment of the mitochondrial cox1 gene was obtained from 112 larvae, pupae and adults (Diamesinae, Orthocladiinae and Tanypodinae) that were collected in different mountain regions of the Alps and Apennines. On the basis of morphological characters 102 specimens were attributed to 16 species, and the remaining ten specimens were identified to the genus level. Molecular species delimitation was performed using: i) distance-based Automatic Barcode Gap Discovery (ABGD), with no a priori assumptions on species identification; and ii) coalescent tree-based approaches as the Generalized Mixed Yule Coalescent model, its Bayesian implementation and Bayesian Poisson Tree Processes. The ABGD analysis, estimating an optimal intra/interspecific nucleotide distance threshold of 0.7%-1.4%, identified 23 putative species; the tree-based approaches, identified between 25-26 entities, provided nearly identical results. All species belonging to zernyi, steinboecki, latitarsis, bertrami, dampfi and incallida groups, as well as outgroup species, are recovered as separate entities, perfectly matching the identified morphospecies. In contrast, within the cinerella group, cases of discrepancy arose: i) the two morphologically separate species D. cinerella and D. tonsa are neither monophyletic nor diagnosable exhibiting low values of between-taxa nucleotide mean divergence (0.94%); ii) few cases of larvae morphological misidentification were observed. Head capsule color is confirmed to be a valid character able to discriminate larvae of D. zernyi, D. tonsa and D. cinerella, but it is here better defined as a color gradient

    2003-10-01

    Full Text Available Vulpes vulpes (Linnaeus, 1758 is one of the most common carnivore in Italy and its spread includes almost the whole national territory. The species shows an high ecological plasticity and a variable diet composition connected in part to human sources. This high adaptability permits the red foxes to colonize different habitats like the suburbs of large cities as well as the small villages located in mountain areas. On the other hand, the tourism pressure seems to assume a great importance in the Alps, also in those areas where the foxes live. So, indirect interactions could take place between these animals and the humans. The role of V. vulpes in the zoonoses has not to be understated since this carnivore could transmit parasitic diseases that are able to cause serious pathologies in humans. This study aims just to investigate on intestinal communities of helmiths of V. vulpes in order to make progress in current knowledge on epidemiological situation in Italian Alps. During 1998-2003, we have examined 450 foxes from Trentino Alto Adige, Veneto, Lombardia and Valle d'Aosta. The specimens collected were found dead or have been hunted (according to national law n. 157/92 in localities situated between 170 and 2200 m a.s.l. The carcasses were carried to the provincial sections of Zooprofilattici Institutes, where the intestine was drawn by each sample and all the material was sent to the Faculty of Veterinary Medicine of Milan. Parasitological examination of the small intestines was performed by the analysis of the whole sediment and counting technique (SCT. Parasites were preserved in alcohol 70° before to be clarified or stained and identified by microscope (Zeiss Axioscop. Mean abundance, mean intensity and prevalence were calculated for each taxon of helminth. Dates of sampling were grouped within the four seasons. Statistic tests were performed with software package SPSS rel. 11.5 and spatial analysis with the

    The hairy maggot blow fly, Chrsomya rufifacies (Macquart) (Diptera: Calliphoridae) was collected in large numbers as both adults and immatures in the Knoxville, Tennessee, area during 1998 and is likely established there. The distribution of this species in the Old World, isothermal data, and its collection from mid-Michigan during 1998 suggest that it will eventually occupy most of the U.S. The forensic importance of C. rufifacies makes it probable that it will factor into an increasing number of medicolegal cases, but the expanding distribution of this species decreases its utility as a geographic indicator when postmortem movement of decedents is suspected.

    The susceptibility status of Aedes albopictus (Skuse; Diptera: Culicidea) larvae collected from 13 districts in Sarawak state, Malaysia was evaluated against five insect growth regulators (IGRs) namely, methoprene, pyriproxyfen, diflubenzuron, cyromazine, and novaluron. Field populations of Ae. albopictus were susceptible to methoprene, pyriproxyfen, cyromazine and novaluron with resistance ratios (RRs) ranging from 0.19-0.38, 0.05-0.14, 0.50-0.95, and 0.75-1.00, respectively. Nevertheless, tolerance towards diflubenzuron (0.33-1.33) was observed in this study. In general, these IGRs exhibited promising results and can be used as alternative control agents against field populations of Ae. albopictus in Sarawak, Malaysia.

    Full Text Available The Hessian fly, Mayetiola destructor Say (Diptera, Cecidomyiidae, is a pest of wheat and belongs to a group of gall-inducing herbivores. This species has a unique life history and several ecological features that differentiate it from other Diptera such as Drosophila melanogaster and blood-feeding mosquitoes. These features include a short, non-feeding adult life stage (1-2 days and the use of a long-range sex pheromone produced and released by adult females. Sex pheromones are detected by members of the odorant receptor (OR family within the Lepidoptera, but no receptors for similar long-range sex pheromones have been characterized from the Diptera. Previously, 122 OR genes have been annotated from the Hessian fly genome, with many of them showing sex-biased expression in the antennae. Here we have expressed, in HEK293 cells, five MdesORs that display male-biased expression in antennae, and we have identified MdesOR115 as a Hessian fly sex pheromone receptor. MdesOR115 responds primarily to the sex pheromone component (2S,8E,10E-8,10-tridecadien-2-yl acetate, and secondarily to the corresponding Z,E-isomer. Certain sensory neuron membrane proteins (i.e., SNMP1 are important for responses of pheromone receptors in flies and moths. The Hessian fly genome is unusual in that it encodes six SNMP1 paralogues, of which five are expressed in antennae. We co-expressed each of the five antennal SNMP1 paralogues together with each of the five candidate sex pheromone receptors from the Hessian fly and found that they do not influence the response of MdesOR115, nor do they confer responsiveness in any of the non-responsive ORs to any of the sex pheromone components identified to date in the Hessian fly. Using Western blots, we detected protein expression of MdesOrco, all MdesSNMPs, and all MdesORs except for MdesOR113, potentially explaining the lack of response from this OR. In conclusion, we report the first functional characterization of an OR from the

    Phlebotomus argentipes Annandale and Brunetti (Diptera: Psychodidae), the established vector for Visceral Leishmaniasis (VL) have shown some morphological variations in India and its subcontinents. The variable egg laying capacity was found in different morphotypes of P. argentipes with maximum in type III followed by type I and II. The fecundity was enhanced by providing 25% glucose soaked filter paper surface in all types. However, significant increase was found in type-I (P < 0.05). The differences in fecundity indicate the biological variations among P. argentipes population. The findings will be helpful in searching out the sibling species among P. argentipes population.

    2007-01-01

    The integration of the sterile insect technique (SIT) in the management of the South American fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is a promising alternative to chemically-based control in those areas where it is sympatric with Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) or other tephritid species for which the SIT is being used. Implementation of the SIT requires the development of a cost effective mass-rearing protocol. In this work, we present demographic and quality control parameters for the A. fraterculus strain reared at the Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considering the rearing cage as the reproduction unit, we observed that fecundity is optimal during the first 3 weeks after the onset of oviposition. Fertility was constant during this period. During 2003 and 2004, some improvements were made to the existing rearing protocol, which resulted in increased larval viability, pupal weight, and adult emergence. Current weekly egg production is 1 million per week. These eggs are used to maintain the colony and to assess quality parameters. Finally, research needs leading to improved yields and fly quality are discussed. (author) [es

    Full Text Available Scuttle flies (Diptera: Phoridae are a diversified insect group of forensic importance. Their frequent presence on human corpses indoors and in concealed environments can be the sole indicators to estimate the minimum post mortem interval (PMImin. However, bionomics of scuttle flies on decomposing animal carcasses are rarely documented indoors. The objective of this research is to observe and document the occurrence of scuttle flies on decomposing animal carcass placed inside a portable cabin maintained at room temperature (≈25.0 °C in Bangi, Malaysia. This study was conducted in two rounds for a period of 40-day each and samplings were carried out in different intervals. Adult scuttle flies were aspirated directly from the carcass and preserved in 70% ethanol. Their larvae and pupae were reared until adult stage to facilitate identification. Megaselia scalaris (Loew, Megaselia spiracularis (Schmitz and Dohrniphora cornuta (Bigot were the scuttle flies found on the carcasses with M. scalaris being the earliest and dominant to colonize the body. This cosmopolitan species proved to be the best indicator to estimate PMImin indoor but in the increased presence of other fly species, it might be relegated to a secondary role. The scuttle flies were also found to coexist with other dipterans of forensic importance in an indoor environment, mainly Chrysomya megacephala (Fabricius (Diptera: Calliphoridae. This information expands the knowledge on the bionomics of scuttle flies on decomposing animal remains indoors.

    Full Text Available The diptera grouped in the family Cecidomyiidae, are considered important pests in the crop of mango (Mangifera indica L.. In the period of 2013-15, prospections were carried out in patios and plantations of several localities of Cuba (Havana, Artemisa, Mayabeque, Ciego de Ávila and Santiago de Cuba, during the stages of vegetative and floral sprouting, to evaluate the presence of insects. Thirteen samplings were made and 25 young leaves and 10 floral shoots were collected per sample, for a total of 325 young leaves and 130 floral shoots in which the number of galls, larvae, pupae and adults of an agallero insect was determined. A total of 2 423 galls were found in young leaves, which represented an average of 7.5 guts per leaf. A total of 207 larvae, 60 pupae and 40 adults were counted among diptera males and females. The morphological characters of the collected insects allowed identifying Procontarinia mangiferae (Felt, belonging to the family Cecidomyiidae, as the cause of the galls in the young leaves and floral shoots in the mango areas sampled.

    Insecticide resistance has become a serious issue in vector management programs. Information on insecticidal resistance and its associated mechanisms is important for successful insecticide resistance management. The selection of a colony of permethrin-resistant Aedes albopictus (Skuse) (Diptera: Culicidae), originating from Penang Island, Malaysia, yielded high larval-specific resistance to permethrin and cross-resistance to deltamethrin. Synergism assays showed that the major mechanism underlying this resistance involves cytochrome P450 monooxygenase. The resistance is autosomal, polygenically inherited and incompletely dominant (D = 0.26). Resistant larvae were reared under different conditions to assess the fitness costs. Under high larval density, larval development time of the resistant SGI strain was significantly longer than the susceptible VCRU strain. In both high- and low-density conditions SGI showed a lower rate of emergence and survival compared with the VCRU strain. Resistant larvae were more susceptible to predation by Toxorhynchites splendens (Wiedemann) (Diptera: Culicidae) larvae. The body size of SGI females reared under high-density conditions was larger compared with females of the susceptible strain. SGI females survived longer when starved than did VCRU females. The energy reserve upon eclosion was positively correlated with the size of the adults.

    Sarconesiopsis magellanica (Diptera: Calliphoridae) is a medically important necrophagous fly which is used for establishing the post-mortem interval. Diptera maggots release proteolytic enzymes contained in larval excretion and secretion (ES) products playing a key role in digestion. Special interest in proteolytic enzymes has also been aroused regarding understanding their role in wound healing since they degrade necrotic tissue during larval therapy. This study was thus aimed at identifying and characterising S. magellanica proteolytic enzyme ES products for the first time. These products were obtained from first-, second- and third-instar larvae taken from a previously-established colony. ES proteins were separated by SDS-PAGE and their proteolytic activity was characterised by zymograms and inhibition assays involving BAPNA (Nα-benzoyl-dl-Arg-p-nitroanilide) and SAPNA substrates, using synthetic inhibitors. The protein profile ranged from ∼69kDa to ∼23kDa; several of them coincided with the Lucilia sericata ES protein profile. Serine-protease hydrolysis activity (measured by zymogram) was confirmed when a ∼25kDa band disappeared upon ES incubation with PMSF inhibitor at pH 7.8. Analysis of larval ES proteolytic activity on BAPNA and SAPNA substrates (determined by using TLCK and TPCK specific inhibitors) suggested a greater amount of trypsin-like protease. These results support the need for further experiments aimed at validating S. magellanica use in larval therapy. Copyright © 2013 Elsevier B.V. All rights reserved.

    Guava leaf tea of Psidium guajava Linnaeus is commonly used as a medicine against gastroenteritis and child diarrhea by those who cannot afford or do not have access to antibiotics. This study screened the antimicrobial effect of essential oils and methanol, hexane, ethyl acetate extracts from guava leaves. The extracts were tested against diarrhea-causing bacteria: Staphylococcus aureus, Salmonella spp. and Escherichia coli. Strains that were screened included isolates from seabob shrimp, Xiphopenaeus kroyeri (Heller) and laboratory-type strains. Of the bacteria tested, Staphylococcus aureus strains were most inhibited by the extracts. The methanol extract showed greatest bacterial inhibition. No statistically significant differences were observed between the tested extract concentrations and their effect. The essential oil extract showed inhibitory activity against S. aureus and Salmonella spp. The strains isolated from the shrimp showed some resistance to commercially available antibiotics. These data support the use of guava leaf-made medicines in diarrhea cases where access to commercial antibiotics is restricted. In conclusion, guava leaf extracts and essential oil are very active against S. aureus, thus making up important potential sources of new antimicrobial compounds.

All the cervical vertebra are free and show dorsoventral compression, differing from the thoracic, lumbar and first caudal vertebra that are relatively uniform, and rounded. From Cd14 se onwards, the vertebra vary in shape and the relationship between width and height is greater than 1, indicating lateral compression. The lack of suture lines in the epiphysis of the ulna and radius indicates the specimen is an adult that has reached ossification maturation.

    This study examined the effects of boat noise pollution on the stress indices of gilthead sea bream (Sparus aurata, Linnaeus 1758). To assess the stress response in these fish, biometric values and plasma parameters such as ACTH, cortisol, glucose, lactate, haematocrit, Hsp70, total protein, cholesterol, triglycerides and osmolarity were analysed. After acclimatization of the animals, the experiment was carried out in a tank fitted with underwater speakers where the fish were exposed to sound treatments (in duplicate) consisting of: 10 days of no sound (control treatment; the animals were only exposed to the experimental tank's background noise) and 10 days of noise derived from original recordings of motor boats, including recreational boats, hydrofoil, fishing boat and ferry boat (vessel noise treatment). The exposure to noise produced significant variations in almost all the plasma parameters assessed, but no differences were observed in weights and fork lengths. A PERMANOVA analysis highlighted significantly increased values (p < 0.05) of ACTH, cortisol, glucose, lactate, haematocrit, Hsp70, cholesterol, triglycerides and osmolarity in the fish exposed to vessel noise for 10 days. This study clearly highlights that anthropogenic noise negatively affects fish, and they are valuable targets for detailed investigations into the effects of this global pollutant. Finally, these experimental studies could represent part of the science that is able to improve the quality of the policies related to management plans for maritime spaces (Marine Strategy Framework Directive 56/2008 CE) that are aimed at stemming this pollutant phenomenon.

    The diamondback moth, Plutella xylostella (Linnaeus), is one of the notorious pests causing substantial loses to many cruciferous vegetables across the nations. The effects of 60 Co-γ radiation on physiology of P. xylostella were investigated and the results displayed that 200 Gy irradiation significantly alters the antioxidant enzyme regulation in six-day-old male pupae of P. xylostella . First, in our research, we detected Oxidase system and stress response mechanism of irradiated pupae, the results displayed that 200 Gy irradiation significantly alters the antioxidant enzyme regulation in six-day-old male pupae of P. xylostella . The levels of superoxide dismutase (SOD) and catalase (CAT) were increased significantly in contrast the level of peroxidase (POD) and glutathione S-transferase (GST) were decreased in 12⁻24 h post-treatment. The heat shock proteins (Hsps) gene expression level was significant increasing, maximum > 2-folds upregulation of genes were observed in peak. However, they also had a trend of gradual recovery with development. Second, we detected the testis lactate dehydrogenase (LDH) and acid phosphatase (ACP) activity found that in male adults testis they increased significantly than control during its development. Thus the present research investigation highlights that the 60 Co-γ radiation treatments alters the physiological development of diamondback moth. The results showed that 200 Gy dosage resulted in stress damage to the body and reproductive system of the diamondback moth.

    Predatory birds such as herons have been used as bioindicators of pollution since they are at the top of their food webs. The tissues of these animals are analyzed for assessing environmental pollution caused by toxic elements. In the present study, adequate experimental conditions were established for determination of trace elements concentrations in the liver samples of Great-white-egret (Ardea alba Linnaeus, 1758) for further application of this specimens as a bioindicator of environmental contamination. Four liver samples were collected from Greatwhite- egrets found in the metropolitan region of Sao Paulo and were they analyzed by the method of neutron activation analysis (NAA). Concentrations of the elements Br, Co, Cs, Fe, Na, Rb, Se and Zn were measured in these liver tissues. The findings of this present study demonstrated that the established procedure for liver sample treatment was appropriate to obtain a homogeneous sample. The method of neutron activation analysis (NAA) was very promising for liver sample analysis for evaluation of environmental contamination. (author)

    Full Text Available The crab eating fox, Cerdocyon thous (Linnaeus, 1766 – Smith, 1839, is a medium sized canid which is found in almost every region of Brazil. It is the only registered native canid specie to be found in the semi-arid Northeastern region of the country. This study had as its objectives: the identification of the helminth fauna common to Cerdocyon thous found in the Caatinga of the state of Paraíba; and the determination of the ecological indications of helminthic infection, hoping to make a favourable addition to the understanding of this little known biome. In this study, 58 animals that were found as ‘roadkill’ on the highways in the municipality of Patos were used. The gastrointestinal helminths from these animals were colected. All the animals in this study were infected with helminths. 16 species of helminths were identified, two being trematodes, one being a cestode, one being an acanthocephalus, and the remaining twelve being nematodes. In this study a new specie, named Pterygodermatites pluripectinata n. sp. Was discovered and its host and location described.

    Full Text Available The aim of this work was to study the annual reproductive cycle of European conger eel (Conger conger,Linnaeus, 1758 through analysis and description of spermatogenesis. A sample of 168 males was capturedbetween September 2008 and August 2009 from the Western coast of Algeria, from Béni Saf. Fish length andweight varied between 26.20-112 cm and 0.45-3.44 kg, respectively.Condition factors (K, gonadosomatic index (G.S.I. and hepatosomatic index (H.S.I. were calculatedmonthly. Factor K reached the minimum in August/September (0.10% corresponding to reproductive periodand a maximum in January (0.18%. Although G.S.I. values revealed to be statistically not significant, therewere two peaks for G.S.I., the first in March, denoting the beginning of spermatogenesis, and the second inAugust/September, indicating the reproduction period. H.S.I. reached a peak in December (1.90%, then thevalue decreased to a minimum in April.Histological analysis of testis allowed us to distinguish 5 stages summarized as follows: Stage 1:Spermatogonia A; Stage 2: Spermatogonia B; Stage 3: Spermatocytes and spermatids; Stage 4: Spermatocytes,spermatids and spermatozoa (cytodifferentiation of spermatids into spermatozoa; Stage 5: Spermatozoa(spermiogenesis or cytodifferentiation of spermatids into spermatozoa.

    We evaluated the effects of supplemental coated and crystalline methionine (Met) on the growth performance and feed utilization of juvenile cobia ( Rachycentron canadum Linnaeus) in a 60-d feeding trial. Fish groups were fed one of six isonitrogenous and isolipidic diets: 1) fishmeal control; 2) un-supplemented experimental (low-fish-meal diet deficient in Met); or 3) one of four Met diets supplemented with crystalline L-Met, cellulose-acetate-phthalate coated L-Met, acrylic-resin coated L-Met, or tripalmitin-polyvinyl alcohol coated L-Met. The test diets were fed to triplicate groups of cobia (initial body weight 5.40±0.07 g) twice a day. The weight gain and specific growth rate of the fish fed the RES diet were highest among the Met-supplemented groups and were 23.64% and 7.99%, respectively, higher than those of the fish fed with the un-supplemented experimental diet ( Pcobia.

    The uranium mining at Caetité (Uranium Concentrate Unit—URA) is in its operational phase. Aiming to estimate the radiological environmental impact of the URA, a monitoring program is underway. In order to preserve the biota of the deleterious effects from radiation and to act in a pro-active way as expected from a licensing body, the present work aims to use an environmental protection methodology based on the calculation of absorbed dose rate in biota. Thus, selected target organism was the Tilapia fish (Tilapia nilotica, Linnaeus, 1758) and the radionuclides were: uranium (U-238), thorium (Th-232), radium (Ra-226 and Ra-228) and lead (Pb-210). As, in Brazil there are no radiation exposure limits adopted for biota the value proposed by the Department of Energy (DOE) of the United States of 3.5×103 μGy y-1 has been used. The derived absorbed dose rate calculated for Tilapia was 2.51×100 μGy y-1, that is less than 0.1% of the dose limit established by DOE. The critical radionuclide was Ra-226, with 56% of the absorbed dose rate, followed by U-238 with 34% and Th-232 with 9%. This value of 0.1% of the limit allows to state that, in the operational conditions analyzed, natural radionuclides do not represent a radiological problem to biota.

    The aim of this study was to verify the in vivo effectiveness of pumpkin seed (Curcubita pepo Linnaeus, 1753) in naturally infected ostriches in the Cariri zone, semiarid region of Paraíba State, Brazil. Forty-eight ostriches were used, African Black breed, of 14 to 36 months old, naturally infected by gastrointestinal nematodes. These animals were divided into four groups of 12 ostriches. Group 1 consists of animals treated with 0.5 g/kg live weight (l. w.) of pumpkin seed meal; group 2 received 1 g/kg l. w. of pumpkin seed meal; group 3 was treated with Albendazole 5 %, at the dosage of 1 mL/10 kg l. w.; and Group 4 was the control group and do not received treatment. Groups 1 and 2 received the treatment for three consecutive days, orally, at intervals of 7 days, totaling nine administrations. The Albendazole 5 % was administered one time, at the beginning of the experiment, according to the manufacturer's recommendations. The groups treated with pumpkin seed showed a significant decrease in egg counts per gram of feces (EPG), wherein group 2 (1 g/kg l. w.) was the most effective. The control and drug groups showed no reduction in EPG. The results of the present study demonstrate that the administration of pumpkin seed was effective in controlling gastrointestinal helminths in naturally infected ostriches.

    The uranium mining at Santa Quiteria (Santa Quiteria Unit - USQ) is in its environmental licensing phase. Aiming to estimate the radiological environmental impact of the USQ, a monitoring program is underway. However, radioprotection of biota is not explicitly mentioned in Brazilian norms. In order to preserve the biota of the deleterious effects from radiation and to behave in a pro-active way as expected by licensing organs, the present work aims to use an environmental protection methodology, based on the calculation of absorbed dose rate in biota.

Since there are no exposition limits for biota, in Brazil, the value proposed by the Department of Energy (DOE) of the United States of 3.5 x 10 3 μGy/y has been used. The derived absorbed dose rate calculated for tilapia was 2.76 x 10 0 μGy/y, that is less than 0.1 % of the limit established by DOE. The critical radionuclide was U-238, with 99% of the absorbed dose rate. This value of 0.1% of the limit allows to state that in pre-operational conditions analyzed natural radionuclides do not represent a radiological problem to the biota. (author)

    Hemocytes of the last larva of the Japanese rhinoceros beetle A. dichotoma (Linnaeus) (Coleoptera: Scarabaeidae) were classified as granulocytes, plasmatocytes, oenocytoids, spherulocytes, prohemocytes, and adipohemocytes. Among these cell types, only the granulocytes became immunologically activated with obvious morphological changes, displaying large amoeba-like, lobopodia-like, and fan-like structures. In addition, their cytoplasmic granules became larger and greatly increased in number. To explore whether these granules could be immunologically generated as phagosomes, total hemocytes were stained with LysoTracker. Greater than 90% of the granulocytes retained the LysoTracker dye at 4 h post-bacterial infection. In flow cytometry analysis, the red fluorescent signal was highly increased at 4 h post-bacterial infection (60.36%) compared to controls (5.08%), as was confirmed by fluorescent microscopy. After 12 h post-infection, these signals returned to basal levels. The uptake of pathogens by granulocytes rapidly triggered the translocation of the microtubule-associated protein 1 light chain 3 alpha (LC3) to the phagosome, which may result in enhanced pathogen killing.

    Full Text Available Ultrastructure of spermatozoa of the crab Ucides cordatus Linnaeus, 1763 is described and illustrated. Three parts can be distinguished: 1. the elongate-ovoid acrosome located anteriorly; 2. the cytoplasmic region; and 3. the nuclear region. The acrosome is composed of a thick electron-dense wall and a less electron-dense subacrosomal space. The cytoplasm region connects the acrosome with the nucleus, and three arms filled with microtubules arise from this region. The nucleus is polymorphous. The spermatozoon of Ucides cordatus follows the general pattern described for other Decapods.

    In recent years, a considerable number of pierid butterflies of the genus Delias have been found from Jinmen Islands, where no available hostplants grow, rendering a proof of cross sea water migration of these butterflies. It is suggested here that these butterflies come from nearby continent of eastern China, visiting the islands for nectar acquisition in seasons when nectar is in short supply because they mostly show up in autumn months. Samples obtained during the survey contained two species, namely Delias pasithoe (Linnaeus, 1767) and Delias acalis (Godart, 1819). Subspecific names applied to both species in eastern China appear to involve nomenclatural problems, with erroneous usage in recent literature.

    Full Text Available Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban forest (Santa Genebra Reservation, located in Campinas, State of São Paulo, southeastern Brazil, 4 out of 36 families of insects collected - Calliphoridae, Sarcophagidae, Muscidae (Diptera and Dermestidae (Coleoptera - were considered of forensic importance, because several species were collected in large numbers both visiting and breeding in pig carcasses. Several species were also observed and collected on human corpses at the Institute of Legal Medicine. The species belonged to 17 different families, 6 being of forensic importance because they were reared from human corpses or pig carcasses: Calliphoridae, Sarcophagidae, Muscidae, Piophilidae (Diptera, Dermestidae, Silphidae and Cleridae (Coleoptera. The most important species were: Diptera - Chrysomya albiceps, Chrysomya putoria, Hemilucilia segmentaria, Hemilucilia semidiaphana (Calliphoridae, Pattonella intermutans (Sarcophagidae, Ophyra chalcogaster (Muscidae, Piophila casei (Piophilidae; Coleoptera - Dermestes maculatus (Dermestidae, Oxyletrum disciolle (Silphidae and Necrobia rufipes (Cleridae.

    Abstract. The Oestrosis is an obligatory and cavitary myiasis of sheep and goat, wild and domestic, caused by the larvae of Oestrus ovis (Linnaeus fly. This study records the presence of O. ovis in the West Central region of Brazil as parasites of goats and sheep. We obtained six larvae from sheep and goats with suspects of oestrosis in Brasília (Brazil originate two females adult of O. ovis, after 20 and 23 days respectively of pupation. This finding is probably associated with expansion and diversification of farming in the Cerrado of the Brazilian central plateau.

    Total and cytosolic concentrations of twenty metals/metalloids in the liver of brown trout Salmo trutta (Linnaeus, 1758) were studied in the period from April 2015 to May 2016 at two sampling sites on Croatian river Krka, to establish if river water contamination with metals/metalloids downstream of Knin town has influenced metal bioaccumulation in S. trutta liver. Differences were observed between two sites, with higher concentrations of several elements (Ag, As, Ca, Co, Na, Se, Sr, V) found downstream of Knin town, whereas few others (Cd, Cs, Mo, Tl) were, unexpectedly, increased at the Krka River spring. However, total metal/metalloid concentrations in the liver of S. trutta from both sites of the Krka River were still mainly below previously reported levels for pristine freshwaters worldwide. The analysis of seasonal changes of metal/metalloid concentrations in S. trutta liver and their association with fish sex and size mostly indicated their independence of fish physiology, making them good indicators of water contamination and exposure level. Metal/metalloid concentrations in the metabolically available hepatic cytosolic fractions reported in this study are the first data of that kind for S. trutta liver, and the majority of analyzed elements were present in the cytosol in the quantity higher than 50% of their total concentrations, thus indicating their possible availability for toxic effects. However, the special attention should be directed to As, Cd, Cs, and Tl, which under the conditions of increased exposure tended to accumulate more within the cytosol. Although metal/metalloid concentrations in S. trutta liver were still rather low, monitoring of the Krka River water quality and of the health status of its biota is essential due to a trend of higher metal/metalloid bioaccumulation downstream of Knin town, especially taking into consideration the proximity of National Park Krka and the need for its conservation.

    Diamondback moth (DBM), Plutella xylostella (Linnaeus), is a notorious pest of brassica crops worldwide and is resistant to all groups of insecticides. The insect system harbors diverse groups of microbiota, which in turn helps in enzymatic degradation of xenobiotic-like insecticides. The present study aimed to determine the diversity of gut microflora in DBM, quantify esterase activity and elucidate their possible role in degradation of indoxacarb. We screened 11 geographic populations of DBM in India and analyzed them for bacterial diversity. The culturable gut bacterial flora underwent molecular characterization with 16S rRNA. We obtained 25 bacterial isolates from larvae (n=13) and adults (n=12) of DBM. In larval gut isolates, gammaproteobacteria was the most abundant (76%), followed by bacilli (15.4%). Molecular characterization placed adult gut bacterial strains into three major classes based on abundance: gammaproteobacteria (66%), bacilli (16.7%) and flavobacteria (16.7%). Esterase activity from 19 gut bacterial isolates ranged from 0.072 to 2.32μmol/min/mg protein. Esterase bands were observed in 15 bacterial strains and the banding pattern differed in Bacillus cereus - KC985225 and Pantoea agglomerans - KC985229. The bands were characterized as carboxylesterase with profenofos used as an inhibitor. Minimal media study showed that B. cereus degraded indoxacarb up to 20%, so it could use indoxacarb for metabolism and growth. Furthermore, esterase activity was greater with minimal media than control media: 1.87 versus 0.26μmol/min/mg protein. Apart from the insect esterases, bacterial carboxylesterase may aid in the degradation of insecticides in DBM. Copyright © 2016 Sociedade Brasileira de Microbiologia.

Many crucial morphological, cellular and tissular changes were observed during both feeding phases, mostly those related to digestive and visual ontogenetic events, such as differentiation of buccopharyngeal cavity and eye development (at hatching; pigmentation and differentiation of cone-photoreceptors (4 dph; opening of the mouth and anus, appearance of intestinal valves (5-6 dph; presence of buccopharyngo-esophageal (5-6 dph and intestinal (9 dph mucous cells; folding of intestinal mucosa (6 dph; development of regional specific digestive musculature (6 dph; typical structure and functionality of the liver (sinusoids, biliary and pancreatic ducts, glycogen, protein and lipid reserves (4-6 dph; and characteristic acinar distribution pattern of eosinophilic zymogen granules of the exocrine pancreas (6 dph. Between 9 and 10 dph, the hake larvae showed evident signs of lipid absorption within enterocytes of the anterior intestinal region and a remarkable process of pynocitosis and intracellular digestion was detected in the posterior intestine (supranuclear inclusions or acidophilic protein vesicles. In hake larvae at 10 dph, a proliferation of renal tubules, spleen differentiation and gill development, as well as the presence of the first thyroid follicle, were clearly distinguished. At this time, stomach gastric gland differentiation was not detected and endocrine pancreas and gill lamellae were not evidenced. However, and interestingly, swim bladder and eyes (developing rods were well differentiated in larval development from 9 dph onwards. In summary, in European hake larval development during the endo-exogenous feeding phase and especially at 9 to 10 dph, most systems, organs

    The cestode species recovered from the spiral intestines of 27 blue sharks (Prionace glauca) (Linnaeus, 1758) are reported from the western coast of Baja California Sur (BCS). The sampling was undertaken on a monthly basis from January 2003 to January 2004. The helminthological examination indicated the presence of four species of cestodes: Platybothrium auriculatum Yamaguti, 1952; Prosobothrium japonicum Yamaguti, 1934; Anthobothrium caseyi (Yamaguti, 1934) Ruhnke & Caira, 2009; and Paraorygmatobothrium prionacis (Yamaguti, 1934) Ruhnke, 1994. Of all the 27 sharks examined, 88.8% were infected with at least one cestode species. The most frequent species was P. auriculatum infecting 85% of the spiral intestines examined. In contrast the species with the highest mean intensity was P. prionacis (80.4 200). The species richness of cestodes in P. glauca is very similar in other regions of the world despite its wide distribution; however, this richness is low compared with other species of sharks within the same family. The feeding and host-specific are important factors that influence the parameters of infection of cestodes in this shark. On the west coast of BCS, Prionace glauca feeds mainly on red crab Pleuroncodes planipes Stimpson, 1860; squids Gonatus californiensis Young, 1972, Ancistrocheirus lesueurii (D'Orbigny, 1842), Haliphron atlanticus Steenstrup, 1861, and low proportion of fish teleosts as Merluccius productus (Ayres, 1855), Sardinops sp. Hubbs, 1929 and Scomber japonicus Houttuyn, 1872. We speculate that these prey could be involved as the second intermediate hosts of these cestodes, as in other members of these genera, although the life cycles of none are known.

  10. Effects of bioirrigation of non-biting midges (Diptera: Chironomidae) on lake sediment respiration

    2016-06-01

    Bioirrigation or the transport of fluids into the sediment matrix due to the activities of organisms such as bloodworms (larvae of Diptera, Chironomidae), has substantial impacts on sediment respiration in lakes. However, previous quantifications of bioirrigation impacts of Chironomidae have been limited by technical challenges such as the difficulty to separate faunal and bacterial respiration. This paper describes a novel method based on the bioreactive tracer resazurin for measuring respiration in-situ in non-sealed systems with constant oxygen supply. Applying this new method in microcosm experiments revealed that bioirrigation enhanced sediment respiration by up to 2.5 times. The new method is yielding lower oxygen consumption than previously reported, as it is only sensitive to aerobic heterotrophous respiration and not to other processes causing oxygen decrease. Hence it decouples the quantification of respiration of animals and inorganic oxygen consumption from microbe respiration in sediment.

    Abstract Two new species of Stenochironomus Kieffer (Diptera: Chironomidae: Chironominae), Stenochironomus brevissimus sp. n. and Stenochironomus linanensis sp. n., are described from China and the male imagines are illustrated. Stenochironomus brevissimus sp. n. can be separated from the so far known species by having very short and small, spatulate superior volsella with two long setae, whereas Stenochironomus linanensis sp. n. is easily separated from the other species of Stenochironomus by the following characters: wings transparent, body yellow, superior volsella finger-like, with nine long setae, elongated inferior volsella with four long setae and one well developed terminal spine; tergite IX with 10−15 long setae medially. A key to the males of Stenochironomus occurring in China is given. PMID:25685018

    In this study, we use DNA barcodes for species delimitation to solve taxonomic conflicts in 86 specimens of 14 species belonging to the Corynoneura group (Diptera: Chironomidae: Orthocladiinae), from the Atlantic Forest, Brazil. Molecular analysis of cytochrome c-oxidase subunit I (COI) gene sequences supported 14 cohesive species groups, of which two similar groups were subsequently associated with morphological variation at the pupal stage. Eleven species previously described based on morphological criteria were linked to DNA markers. Furthermore, there is the possibility that there may be cryptic species within the Corynoneura group, since one group of species presented internal grouping, although no morphological divergence was observed. Our results support DNA-barcoding as an excellent tool for species delimitation in groups where taxonomy by means of morphology is difficult or even impossible.

    Correct species identification and development data of insects associated with a cadaver can help estimate the time of colonization which could be used to infer a minimal post-mortem interval (minPMI) for forensic investigations. Human remains are found in a variety of locations ranging from open fields to inside automobiles. We report the investigation of blow fly larvae collected from a decomposing body located in the trunk of a car. There were two blow fly (Diptera: Calliphoridae) species: Achoetandrus rufifacies (Macquart) and Chrysomya megacephala (Fabricius). Blow flies can enter the vehicle and colonize human remains. Based on age estimations of third stage larvae of A. rufifacies, the minPMI was estimated to be 4-5 days, which was within the range of 3-5 days estimated by other forensically relevant information.

    Full Text Available The objective of this research was to evaluate, in laboratory, the development of Lutzomyia intermedia and Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae larvae, vectors of leishmaniasis in Brazil, in the following diets: industrialized food for rabbits, dogs, hamsters and aquarium fishes, besides liver powder, cooked lettuce, wheat germ, beer yeast, oat, wheat bran and a diet denominated aged food. Except wheat bran for L. intermedia, all diets provided adequate development for both species, which showed that any of them can be used in laboratory insectaries for these insects. L. intermedia showed better development with most nutritious diets and both species presented better development with aged food. Fungi as an additional nutrient source for L. intermedia and L. longipalpis is suggested.

    Aedes aegypti (L.) (Diptera: Culicidae) female mosquitoes infected systemically with Sindbis virus (SINV) took longer than uninfected mosquitoes to locate and fully engorge on blood. On days 7 and 14 postexposure, blood feeding took 1.3 and 1.5 times longer in mosquitoes with a disseminated SINV infection, respectively. SINV dissemination did not affect the average weight of unfed Ae. aegypti, but did result in a 10 and 12% increase in blood imbibed compared with mosquitoes without a positive SINV dissemination and non-SINV-exposed mosquitoes, respectively. Ae. aegypti mosquitoes with a disseminated SINV infection fed an average of 4 h sooner than uninfected mosquitoes when offered a bloodmeal contained inside a DEET (N,N-diethyl-3-methylbenzamide) saturated (30%) bovine sausage casing. Together, these results indicate that behavioral changes in mosquito host-seeking, blood feeding and sensitivity to DEET occurred in mosquitoes after SINV infection and dissemination.

    Infection of Aedes aegypti (L.) (Diptera: Culicidae) with Edhazardia aedis (Microsporidia: Culicosporidae) reduced mean human host attraction and landing/probing rates in female mosquitoes by 53 and 62%, respectively, compared with rates in microsporidia-free females. Infection with E. aedis reduced the average weight of unfed female mosquitoes by 4%, caused them to imbibe 23% less blood, and to lay 30% fewer eggs than healthy females. In contrast, E. aedis-infected mosquitoes required 20% more time (>1 h) than healthy females to bite skin treated with 15% DEET. Statistically significant morbidity in E. aedis-infected females was indicated by reductions in host attraction and landing/probing responses, the mass of unfed and blood-engorged females, and fecundity, and by increased DEET repellency.

    Full Text Available Hemipyrellia ligurriens (Diptera: Calliphoridae is a forensically important blow fly species presented in many countries. In this study, we determined the morphology of all stages and the developmental rate of H. ligurriens reared under natural ambient conditions in Phitsanulok province, northern Thailand. Morphological features of all stages based on observing under a light microscope were described and demonstrated in order to use for identification purpose. Moreover, development time in each stage was given. The developmental time of H. ligurriens to complete metamorphosis; from egg, larva, pupa to adult, took 270.71 h for 1 cycle of development. The results from this study may be useful not only for application in forensic investigation, but also for study in its biology in the future.

    Full Text Available The Diptera (true flies is one of the most species-abundant orders of Insecta, and it is also among the most important flower-visiting insects. Dipteran fossils are abundant in the Mesozoic, especially in the Late Jurassic and Early Cretaceous. Here, we review the fossil record and early evolution of some Mesozoic lower brachyceran flies together with new records in Burmese amber, including Tabanidae, Nemestrinidae, Bombyliidae, Eremochaetidae, and Zhangsolvidae. The fossil records reveal that some flower-visiting groups had diversified during the mid-Cretaceous, consistent with the rise of angiosperms to widespread floristic dominance. These brachyceran groups played an important role in the origin of co-evolutionary relationships with basal angiosperms. Moreover, the rise of angiosperms not only improved the diversity of flower-visiting flies, but also advanced the turnover and evolution of other specialized flies.

    Full Text Available Five bee-fly species (Bombyliidae, Diptera have been listed in this paper as new to the Kingdom of Saudi Arabia. Four of the recorded species have been identified to the level of species, namely: Bombomyia discoidea (Fabricius, 1794, Spogostylum candidum (Sack, 1909, Exoprosopa linearis Bezzi, 1924, and Exoprosopa minos (Meigen, 1804, while the fifth one only to genus, Desmatoneura sp. The species have been collected from Al-Baha and Asir Provinces in the south-western part of the Kingdom. One of the four identified species, Exoprosopa linearis, has an Afrotropical affinity, and another two, Spogostylum candidum and Bombomyia discoidea, have considerable Afrotropical distributions, and this result agrees to some extent with studies considering these parts of the Arabian Peninsula, including Al-Baha and Asir Provinces, having Afrotropical influences and may be included in the Afrotropical Region rather than in the Palaearctic Region or the Eremic zone.

    Full Text Available Predatory behavior of Pseudodorus clavatus (Diptera, Syrphidae on aphids tended by ants. In this study, we examined the interactions between myrmecophilous aphids, their ant-guards and a predatory syrphid species, Pseudodorus clavatus (F.. Larvae of this predator were found in the colonies of three aphid species: Aphis gossypii, A. spiraecola and Toxoptera sp., which were tended by eight ant species, especially Camponotus. Hoverfly larvae managed to infiltrate the aphid colonies and consume nymphs. Predator larvae exhibited inconspicuous movements and were not detected by ants which were commonly observed touching and antennating the larvae they come into contact. These results suggest that behavioral and chemical cues are involved in the infiltration and on the successful predation of syrphids upon aphids.
