    The wide geographical distribution of ground beetles Pterostichus oblongopunctatus makes them very likely to be exposed to several environmental stressors at the same time. These could include both climatic stress and exposure to chemicals. Our previous studies demonstrated that the combined effect of nickel (Ni) and chlorpyrifos (CHP) was temperature (T)-dependent in adult P. oblongopunctatus. Frequently the different developmental stages of an organism are differently sensitive to single stressors, and for a number of reasons, such as differences in exposure routes, their interactions may also take different forms. Because of this, we studied the effects of the same factors on the beetle larvae. The results showed that all factors, as well as their interactions, influenced larvae survival. The synergistic effect of Ni and CPF was temperature-dependent and the effect of Ni x T interaction on the proportion of emerged imagines indicated stronger toxicity of Ni at 25 deg. C than at 10 deg. C. - Combined negative effects of nickel and chlorpyrifos on carabid beetles depend on ambient temperature.

    A growing body ofevidence shows that climate change can alter the phenology of plants and animals.In this study long-term data from the UK Environmental Change Network (ECN) were analyzed to investigate whether there has been a change in the phenology of the ground beetle Pterostichus madidus (Fabricius,1775).Pitfall trap data were available from 12 ECN sites across the United Kingdom,most of which have been in operation for more than 15 years.Weather and vegetation datasets were also utilized.Pitfall trap lines were categorized to eight vegetation types.Trend analysis over time was carried out first using all the available dates of capture events,then the datasets grouped by vegetation type and site.Shifts in high-activity periods were also analyzed.P.madidus appearance dates advanced significantly at seven sites and in five vegetation types.Peak activity advanced at two sites.At one site the timing of activity became significantly later.The last day of activity did not change significantly,supporting the theory that the cessation of the activity period is more likely to be controlled by photoperiod than temperature.The relationships between phenological variables and climatic factors were also investigated.However,no significant correlations were detected.These results demonstrate that between 1992 and 2008,phenology ofP madidus at seven sites from the eight analyzed has changed.Global warming may be driving these changes and future work will investigate underlying processes.

    Full Text Available Shallow subterranean environments have recently received attention as a habitat for Carabidae beetles, and many new species have been discovered using collection techniques devised for this habitat. We report the discovery of two new species of the macrogenys species group of the Pterostichus subgenus Nialoe Tanaka, 1958, collected by subterranean baited traps in northern Honshu, Japan. Pterostichus shinbodakensis Sasakawa & Itô, sp. n. is described from Mt. Shinbodake, Niigata Prefecture, and P. tateishiyamanus Sasakawa & Itô, sp. n. is described from the southeastern foot of Mt. Tateishiyama, Fukushima Prefecture. Comparative male genital morphology shows that among the known species, the two new species are most closely related to P. falcispinus Sasakawa, 2005 and P. chokaisanus Sasakawa, 2009, respectively. In addition, sympatric occurrence of P. shinbodakensis with a smaller, unidentified species of the species group was also confirmed. The implications of these results for future studies of the macrogenys species group, as well as those of Nialoe, are discussed.

Males of Pterostichus bousqueti and Pterostichus lolo are easily distinguished from each other and the seven previously described Pseudoferonina species by the form of the median lobe of the aedeagus, and from most individuals of the other species of Pseudoferonina in Idaho by features of pronotal shape and macrosculpture. Both species appear to be obligate ripicolous hygrophiles, restricted in distribution primarily to the margins of small montane streams in forested areas. Widespread intensive stream surveys for Pseudoferonina over many years indicate the geographic ranges of both species are highly localized, and additional undescribed species may occur in Idaho.

    2011-01-01

    Nebria brevicollis (Fabricius) is one of the most frequently encountered and widely distributed carabid beetles in Europe. Until recently, the only North American records were based on two single specimens, both from the 1930's in southeastern Canada. In 2008, this species was found at thirteen different sites in five counties in northwestern Oregon. As of the end of 2010, it has been found in thirty-four different sites in ten Oregon counties, with a north-south range of ~150 km and an east-west range of ~90 km. It was also detected in 2010 in southwestern Washington (Vancouver), just north of Portland and the Columbia River.The ecological amplitude of Nebria brevicollis in Oregon rivals that of the most eurytopic native carabid species, e.g., Pterostichus algidus LeConte and Scaphinotus marginatus (Fischer von Waldheim). It has been found in highly degraded heavy industrial sites, agricultural fields, city parks, gardens, second growth woodlands, mature conifer forests, montane rock gardens, and otherwise pristine stands of old growth noble fir, with elevations ranging from essentially sea level to 1,249 meters. Climates at these locales vary from that of the Mediterranean Willamette Valley floor, where snow rarely occurs and summers are hot and dry, to the summit of the Oregon Coast Range, where deep snow may be present from November through April and summers are cool. The carabid communities in which Nebria brevicollis has been found range from those predominantly of fellow exotic species, e.g., at heavily perturbed sites, to those where it is the only exotic species, such as at the Coast Range summit.Nebria brevicollis is clearly an invasive species in that it is not restricted to anthropogenic habitats, is rapidly expanding its North American range, and can be abundant in essentially pristine settings. What is not yet clear is whether it is or will become a damaging species. Although it is already the most abundant carabid species in some settings, based upon

    Full Text Available We examined polymorphism in an urban population of the ground beetle Pterostichus melanarius (Illiger, 1798 in forest plantations on the outskirts of Dnipropetrovsk (Ukraine. We took measurements for 130 males and 95 females according to 14 metric, 10 non-metric parameters and 10 indices. According to 13 out of the 14 metric parameters (except for the length of the flight wings P. melanarius showed a significant sexual dimorphism. The female specimens showed a normal distribution in body length and the males showed a significant positive excess. The 10 most significant body proportions of the ground beetles showed much lower sexual differences (0.26±0.86% compared to linear measurements (6.56±0.96%. Females and males are practically isomorphic: when one metric parameter decreases, another decreases proportionally. Statistically significant differences between males and females were registered only for the ratio of elytra to length of prothorax, width of elytra to maximum width of prothorax and length of elytra to their width. A highly significant excess was registered in 6 out of 10 assessments of body proportions for females and 5 out of 10 for males. The coefficient of variation is minimal for body proportions and is maximal for metric parameters, which proves the existence of isomorphic differences between P. melanarius males and females. Out of 10 non-metric parameters a statistically significant sexual dimorphism (P=0.01 was registered only for the shape of the front edge of the labrum (males mostly have a slightly concave, and females a strongly concave front edge of the labrum. Using PCA analysis it was established that 45.2% of the morphological variability of the studied population depends upon the individuals’ sex: the whole complex of metric parameters (length and width of head, prothorax, elytra and parts of head, body height taken together synchronically varies among individuals of different sex.

    1995-01-01

    It is generally believed that copper causes changes in carabid communities indirectly by reducing food availability, because these animals are frequently found to have only slightly elevated metal contents even close to pollution sources. Using computer-centered video tracking, the locomotor...... behavior of adult Pterostichus cupreus carabid beetles was quantified after being raised on copper-contaminated food and soil during larval development. Copper was found to have an acute toxic effect measured in larval mortality, to cause a slight increase in the developmental period of males......, but not to effect the emergence weights of adults of either sex. This toxic effect on the larvae was preserved through pupation to the surviving adults, which were normal in size and appearance, but displayed a dramatically depressed locomotor behavior. Copper analysis of these adults revealed that copper levels...

    Full Text Available The features of interrelations of Pterostichus melanarius (Illiger, 1798 with the soil and litter mesofauna species are considered. In the conditions of forest ecosystems of steppe Dnieper region P. melanarius demonstrates trophic preference for І order zoofagoes (body mass 8.0–31.9 mg and also sapro- and phytofagoes (more than 128 mg of body mass. P. melanarius is able to change the trophic load between invertebrates’ populations depending on their number in the ecosystem. In comparison with the other ground beetle species, the P. melanarius has an extraordinarily wide trophic niche. That is one of principal reasons of the high quantity of P. melanarius in many anthropogenic and transformed ecosystems.

A diet consisting of decomposing horse flesh was used, and the relation of 1 larva/g diet was established. The development of the two species was done in pure and associated cultures. The association with Chrysomya albiceps influenced the post-embrionary development period and the weight of mature larvae of the C. megacephala, reducing their. Such weight decrease, along with the predation of larvae of C. megacephala larvae, yelded a decrease in survival in all of the stages. Larvae of this species showed an increase in its weight when associated with Cochliomyia macellaria. The native species responded to the association by reducing its body weigth and its viability. This association doesnt influence the duration of post-embrionary development.

    Senna occidentalis (L) Link (formerly called Cassia occidentalis) is a toxic leguminous plant found ubiquitously as a contaminant of crops. All parts of the plant are toxic, but most of the S. occidentalis toxicity is found in the seeds. S. occidentalis has been shown to be toxic to several animal species, causing degenerative lesions mainly in muscles. This is the first report describing alterations in chick lymphoid organs caused by S. occidentalis seeds. The objectives of this study were to describe the effects of the treatment with seeds and its fraction external tegument (TE) on the development of chicks and their lymphoid organs bursa of Fabricius and spleen. Chicks that received a commercial ration with 1% TE had reduced body and lymphoid organ weights. The bursa of Fabricius presented reduction in the diameters of the follicles, and in the thickness of the cortical and medullary regions. The spleen presented depleted lymphoid tissue in the white pulp. These results indicate that the active principle of S. occidentalis is more concentrated on its TE fraction, and that it can cause weight loss as well as alterations in the lymphoid organs in chicks. The consequences of these alterations should be further investigated.

    In estimating the postmortem interval (PMI) using maggots obtained during autopsy, the forensic entomologist makes decisions regarding the effects of low-temperature storage of the body on the insects. In this case report, a corpse was found in an abandoned house in the residential area of Bukit Mertajam, Penang, Malaysia. The maggots were found to be alive inside the mouth of the deceased although the corpse had been in the morgue cooler for 12 days. The maggots were reared and identified as Chrysomya megacephala (Fabricius). The emerged adult flies were kept as a stock colony, and the duration of development under the indoor fluctuating temperature regime was studied. The total duration of developmental process of this species was 9.5 ± 0.5 days, and the PMI estimated was 3.2 ± 0.6 days. This case report demonstrates the survival of Ch. megacephala maggots for 12 days and their growth inside the morgue cooler.

    Full Text Available Animals may respond to habitat quality and habitat edges and these responses may affect their distribution between habitats. We studied the movement behaviour of a ground-dwelling generalist predator, the carabid beetle Pterostichus melanarius (Illiger. We performed a mark-recapture experiment in two adjacent habitats; a large plot with oilseed radish (Raphanus sativus and a plot with rye (Secale cereale. We used model selection to identify a minimal model representing the mark-recapture data, and determine whether habitat-specific motility and boundary behaviour affected population redistribution. We determined movement characteristics of P. melanarius in laboratory arenas with the same plant species using video recording. Both the field and arena results showed preference behaviour of P. melanarius at the habitat interface. In the field, significantly more beetles moved from rye to oilseed radish than from radish to rye. In the arena, habitat entry was more frequent into oilseed radish than into rye. In the field, movement was best described by a Fokker-Planck diffusion model that contained preference behaviour at the interface and did not account for habitat specific motility. Likewise, motility calculated from movement data using the Patlak model was not different between habitats in the arena studies. Motility (m2 d-1 calculated from behavioural data resulted in estimates that were similar to those determined in the field. Thus individual behaviour explained population redistribution in the field qualitatively as well as quantitatively. The findings provide a basis for evaluating movement within and across habitats in complex agricultural landscapes with multiple habitats and habitat interfaces.

    Full Text Available Regarding the remarkable role of bursa of Fabricius as a primary lymphoid organ in poultry, this study aimed to evaluate the effect of long term administration of Zataria multiflora as an herbal immunomodulatory agent on histological features of this organ in broiler chickens. To this end, fifty, one-day old chickens were randomly divided into five equal groups and fed with diets contained 0.5, 1, 1.5, and 2% of Z. multiflora (experimental groups or basal diet (control group for 45 days. On day 46, birds were slaughtered and bursa of Fabricius was dissected immediately. 6μm-thick transverse sections were made and stained with H&E for measuring height of pelicae, follicular width as well as thickness of follicular cortex and medulla using a linear graticule. Number of follicles in plicae was also counted under light microscope. The results showed a dose dependent increase in all histomorphometric parameters due to Z. multiflora administration and the highest increase was in the thickness of follicular cortex of birds treated with 2% Z. multiflora. In conclusion, dietary inclusion of Z. multiflora during the rearing period of broilers, dose dependently affects histological structures of bursa of Fabricius in a way that may enhance its role as a lymphoid organ

    Full Text Available The first half of the twentieth century saw the rise of a new type of novel that straddled the divide between popular entertainment and legitimate culture by combining ‘high’ and ‘low’ literary forms and catering en masse for the tastes of an expanding middleclass reading public. In this article we want to explore the ways in which the novels La Madone des sleepings (1925 by the bestselling French novelist Maurice Dekobra and Venetiaansch avontuur [Venetian adventure] (1931 by the Dutch author Johan Fabricius fit into this broad category of the middlebrow novel and how their use of adventure as a structural devise might complicate the common view of the middlebrow novel as a form of domestic realism.

    Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 {+-} 1 deg C), RH (60 {+-} 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean and peanut seeds and privet Ligustrum lucidum Ait. fruit (Oleaceae)]. All three artificial diets allowed full development. The diet containing sunflower oil was the most suitable for N. viridula while E. heros developed better on a diet composed of soybean oil. Data indicated that the artificial diets were inferior to the natural diet. The artificial diets were more adequate for E. heros. (author)

    Stomorhina discolor (Fabricius), a species of blow fly that mimics wasps, is distributed worldwide, but detailed information about characteristics of its adult terminalia is incomplete. To help fill this gap in the information, the morphology of adult stages of S. discolor was investigated using light microscopy and scanning electron microscopy. Observations using the light microscope revealed unique characteristics of the male genitalia that are markedly different from other blow fly species. More morphological detail, including observation of several sensilla (e.g., sensilla trichoid and sensilla basiconica) along the male terminalia and female ovipositor, was seen under the scanning electron microscope. These details can be taxonomically valuable for identifying males and females of S. discolor and may help address matters concerning copulation in this species. PMID:28085083

    Full Text Available Lantana camara L. is a widespread plant species mostly native to subtropical and tropical regions of the world. In this study, insecticidal and repellent activities of L. camara essential oil were evaluated against Callosobruchus maculatus (Fabricius (Col: Bruchidae. Analysis of chemical composition by gas chromatography/mass spectrometry (GC/MS showed high amounts of sesquiterpenes, mainly α-humelene (23.3% and cis-caryophyllene (16.2%. The results showed that the essential oil of L. camara has strong repellent activity against adults of C. maculatus at all tested concentrations. After 2 and 4 h, 97.4 and 100% repellency was seen at highest concentrations of 0.4 μL cm-2, respectively. Moreover, the oil was found to be toxic to adults when applied by fumigation. Responses varied with the gender of insect and exposure time. The LC50 values were 282.7 and 187.9 μL L-1 for females and males, respectively. An increase in the exposure time from 3 to 24 h caused increasing in mortality from 23.6 to 100% in males and from 14.1 to 97.1% in females, at highest concentration (1160 μL L-1. According to these results, L. camara essential oil may be useful as an alternative for bean protection against C. maculatus.Lantana camara L. es una especie vegetal nativa de las regiones subtropicales y tropicales del mundo.

    Full Text Available Bursa Fabricius is a target organ of gumboro virus infection which is often damaged after vaccinationusing hot intermediate gumboro live vaccine. The purpose of this study was to assess pathologic effect oflocal and commercial gumboro vaccines . As many as 45 embryo chicken eggs at nine day old were used inthis research, then grouped into three groups of 15 embryos chicken eggs each, these were: Embryo chickeneggs without vaccination (Group I, vaccinated with IBD intermediate plus commercial vaccine (Group IIand IBD intermediate plus local vaccine (Group III. Vaccinations were done at 14 days old. All groups thenterminated each three embryos at 12 hours, 1, 2, 3 days post vaccination. The results showed that pathologicanatomic lesions could not be detected. Whereas pathologic lesions were detected in the group that werevaccinated with intermediate plus local IBD observed more severe than in the group that vaccinated withintermediate plus commercial IBD. Lesions such as edema, hemorrhages, necrosis of lymphoid cells wereobserved microscopically in embryo at 12 hours, 1, 2 and 3 days post vaccination in Group II and group III.The lesions were more severe at two days post vaccination causing some lymphoid follicles disappeared at three days post vaccination. However, they were not detected again in the bursa Fabricius three days afterhatching. Cells containing antigens of gumboro were detected in the bursa Fabricius of chicken embryo atone day until three days post vaccination, then disappeared after three days post hatch. It was concludedthat pathologic description of bursa fabricius showed that virus vaccines used for vaccinated IBD in ovowere still virulent, that can cause histopathologic lesions. The viruses are suggested to be more attenuatedbefore using as vaccine in ovo.

    Full Text Available For the first time the pollination of a poorly known, terrestrial orchid, Habenaria pleiophylla Hoehne & Schlechter, 1921 (Orchidaceae by a passion vine butterfly, Heliconius erato phyllis (Fabricius, 1775 (Lepidoptera, Nymphalidae is reported. Number of pollinia-carrying individuals was determined on a population of H. erato phyllis in Horto Florestal Barba Negra, Barra do Ribeiro County, Rio Grande do Sul State. The pollination mechanism was described under laboratory conditions, in association with the butterfly feeding habit and the orchid flower morphology. Habenaria pleiophylla pollinia are cemented during nectar feeding on the ventral portion of the compound eyes near H. erato phyllis proboscis base. The pollinia are transferred to the stigma of other flowers during subsequent visits. Both males and females of H. eralo phyllis frequently visit H. pleiophylla flowers in the Barba Negra Forest. About forty percent of field collected adults had attached pollinia, ranging in number from one to 19 per individual. Thus, H. eralo phyllis may play an important role in the reproductive biology of this H. pleiophylla population.

    Full Text Available The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the first time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM, Transmission Electron Microscopy (TEM and confirmed by Atomic Force Microscopy (AFM. Our study clearly denotes that the Indian rock honey bee Apis dorsata possess calcium silicate and calcium phosphate nanoparticles on its body surface of 5-50 nm in diameter. In particular, the nanoparticles on the abdomen and thorax of A. dorsata have an average diameter of about 10 nanometers and they are smaller than those found on wings of the same bees which are about 20 nanometers. The nanoparticles found are different of the ones previously observed on honey bees or other insects. The origin and role of these natural nanoparticles on the body of the Indian rock bee need to be to be further investigated; more research in the subject might raise important aspects in relation to the conservation of these unique pollinators.

    Nickel accumulated in midugt of Spodoptera litura Fabricius could induce the expression of metal-Iothionein, one of the most important detoxification proteins in organisms. In the present study, the effects of dietary nickel on the activities of detoxification enzymes, such as carboxylesterase (CarE) and glutathione S-transferase (GST) in the midgut of S. litura larvae have been studied to get an un-derstanding of the detoxification mechanisms of S. litura larvae to excessive nickel. Results showed that CarE activities in the midgut of the 5th instar larvae decreased at lower levels of nickel (≤5 mg/kg), while increased with increasing nickel doses at higher levels of nickel (≥10 mg/kg) exposure in suc-cessive 3 generations. CarE activities of the 6th instar larvae were also characterized as inhibited at low levels of nickel exposure, and improved at higher levels in the 1st generation. CarE activities of 6th instar larvae in the 2rid and 3rd generations were all lower than that in control. However, GST activities in the midgut of the 5th and 6th instar larvae all increased with increasing nickel doses (1-20 mg/kg) in diets.

    2012-06-01

    The genetic diversity of Amblyomma variegatum (Fabricius) from four Caribbean islands and five African countries was compared by analyzing the sequences of three gene fragments, two mitochondrial (12SrDNA and D-Loop-DL), and one nuclear (intergenic transcribed spacer 2 [ITS2]). Genetic variability of the ITS2 DNA fragment consisted of only uninformative single nucleotide mutations, and therefore this gene was excluded from further analyses. Mitochondrial gene divergences among African populations and between Caribbean and African populations were very low. Nevertheless, the data suggest that A. variegatum is divided into distinct East and West African groups, the western group including all Caribbean samples. Phylogenetic analyses of the 12SrDNA and DL gene sequences showed that the West African A. variegatum clustered in a well-supported monophyletic clade, distinct from eastern paraphyletic lineages. Sequences of A. variegatum from the Caribbean were embedded in the West African clade, which supports the known West African historical origin for these ticks.

    The orb-weaving spider genus Gasteracantha Sundevall, 1833 (Araneidae) is notable for its pronounced sexual size dimorphism. Gasteracantha females are characterized by having a highly sclerotized "spiny" abdomen varying in relative size and number of spines, as well as abdomen dorsally and ventrally provided with varying numbers of sigillae (Cambridge 1879). The genus currently includes 70 described species and 31 subspecies (World Spider Catalog 2014). The Oriental species Gasteracantha geminata (Fabricius, 1798) was originally described from Ramnad (now known as Ramanathapuram) in Tamilnadu State of Southern India based on an unspecified number of female specimen(s). The female of this species has been described and illustrated several times by various authors. Its male is only known from the description of Simon (1895). Simon's original description of the male of G. geminata was supported by two simple but beautiful and informative illustrations: a retrolateral view of the cephalothorax and a dorsal view of the abdomen (Simon 1895, figs. 886, 887). However we lack a clear and detailed description of the male genitalia. The present paper provides detailed redescription of G. geminata and illustrations of the male pedipalp.

    Full Text Available Energetic cost of digging behavior in workers of the leaf-cutting ant Atta sexdens (Fabricius. During nest excavation, leaf-cutting ant workers undergo reduction in their body reserve, particularly carbohydrates. In order to estimate the energetic cost of digging, groups of 30 workers of the leaf-cutting ant Atta sexdens were sealed in a hermetic chamber for 24, 48 and 72 hours, with and without soil for digging, and had the CO2 concentration measured using respirometric chambers as well as volume of soil excavated (g. As expected, the worker groups that carried out soil excavation expelled more carbon dioxide than the groups that did not excavate. Therefore, a worker with body mass of 9.65 ± 1.50 mg dug in average 0.85 ± 0.27 g of soil for 24 hours, consuming ca. 0.58 ± 0.23 J. In this study, we calculate that the energetic cost of excavation per worker per day in the experimental set-up was ca. 0.58 J.

    Aflatoxin B1 is known as a mycotoxin that develops various health problems of animals, the effects of AFB1 on thymus and bursa of Fabricius in chickens are not clear. The objective of this study was to investigate the apoptosis of thymus and bursa of Fabricius in broilers fed with AFB1 . Two hundred Avian broilers were randomly divided into four groups of 50 each, namely control group and three AFB1 groups fed with 0.15 mg, 0.3 mg, and 0.6 mg AFB1 /kg diet, respectively. In this study, flow cytometer and immunohistochemical approaches were used to determine the percentage of apoptotic cells and the expression of Bax, Bcl-2, and Caspase-3. The results showed that consumption of AFB1 diets results in increased percentage of apoptotic cells and increased expression of Caspase-3 in both thymus and bursa of Fabricius. The expression of Bax was increased and the expression of Bcl-2 was decreased in the thymus, but no significant changes in Bax and Bcl-2 expression were observed in the bursa of Fabricius when broilers fed with AFB1 . These findings suggest that adverse effects of AFB1 on thymus and bursa of Fabricius in broilers were confirmed by increased apoptotic cells and abnormal expression of Caspase-3. © 2015 Wiley Periodicals, Inc.

    Resumo. Conhecidas como “libélulas helicóptero”, as espécies do gênero Mecistogaster (Coenagrionidae são caracterizadas pelo grande tamanho quanto comparado as outras espécies de Odonata, pela habilidade de bater as duas asas anteriores e posteriores em sentidos opostos e preferência por habitats de interiores de matas. Estas se alimentam de aranhas e dependem principalmente de troncos de árvores ou plantas, como bromélias, capazes de acumular água para a postura dos ovos. A relação com ambientes de fitotelmatas faz com que as espécies deste gênero sejam sensíveis a fragmentação florestal e a alterações em seu habitat. No Brasil há registros de sete espécies, com ocorrências principalmente em regiões de floresta amazônica. Mecistogaster linearis (Fabricius tem uma ampla distribuição, sendo reportada, até então no país, para os estados do Acre, Amazonas, Roraima, Pará, Rondônia, Mato Grosso, Rio de Janeiro e São Paulo. Nesta comunicação, reportamos o primeiro registro desta espécie para o estado de Mato Grosso do Sul, Brasil, coligida no município de Corumbá, região do Pantanal.

    Full Text Available During the past few years, there has been considerable interest on the effects of stocking density on broiler behavior and immunity. Stress may cause immunodeficiency by affecting cell and humoral responses, as well as body weight decrease, and foot-pad dermatitis. The aim of this study was to study histomorphological changes of the bursa of Fabricius in broilers submitted to three different stocking densities (10, 15, and 20 birds/m² from one to 42 days of age. Three birds from each group were sacrifieced on days 7 and 42. The bursa was collected, fixed, and processed for histomorphometric assessment using a Kontrom KS 400 image analyzer. Data were analyzed by Biostat 3.0 (Tukey Test. The results of average cortical area percentage in bursal follicles of 6-week-old birds were 45.12a (10 birds/m², 30.43b (15 birds/m², and 23.77b (20 birds/m². Average body weight was 2.58a kg (10 birds/m², 2.56a Kg (15 birds/m², and 2.47b Kg (20 birds/m², respectively. The percentage of foot-pad dermatitis in 6-week-old birds was 3.33a (10 birds/m², 17.76b (15 birds/m², and 49.17c (20 birds/m². These differences were statistically significant at a P<0.05 level. Under these experimental conditions,, it was concluded that the best stocking density to produce broilers is between 10-15 birds per square meter.

    Analysis on fly artifacts produced by forensically important blowfly, Chrysomya megacephala (Fabricius) (Diptera:Calliphoridae), revealed several unique patterns. They can be divided into fecal spots, regurgitation spots and swiping stains. The characteristics of fecal spots are round with three distinct levels of pigmentation; creamy, brownish and darkly pigmented. Matrix of the spots appears cloudy. The round spots are symmetrical and non-symmetrical, delineated by irregular and darker perimeter which only visible in fairly colored fecal spots. Diameter of these artifacts ranged from 0.5 mm to 4 mm. Vomit or regurgitation spots are determined by the presence of craters due to sucking activity of blowflies and surrounded by thickly raised and darker colored perimeter. The size of these specks ranged from 1 mm to 2 mm. Matrix of the spots displays irregular surface and reflective under auxiliary microscope light. Swiping stains due to defecation by flies consists of two distinguishable segments, the body and tail. It can be seen as a tear drop-like, sperm-like, snake-like and irregular tadpole-like stain. The direction of body and tail is inconsistent and length ranged between 4.8 mm to 9.2 mm. A finding that should be highlighted in this observation is the presence of crater on tadpole-like swiping stain which is apparent by its raised border characteristic and reflective under auxiliary microscope light. The directionality of this darkly brown stain is random. This unique mix of regurgitation and swiping stain has never been reported before. Highlighting the features of artifacts produced by flies would hopefully add our understanding in differentiating them from blood spatters produced from victims at crime scenes.

  13. Differential Recruitment of Camponotus femoratus (Fabricius) Ants in Response to Ant Garden Herbivory.

    Although several studies have shown that ants can recognize chemical cues from their host plants in ant-plant systems, it is poorly demonstrated in ant gardens (AGs). In this interaction, ant species constantly interact with various epiphyte species. Therefore, it is possible to expect a convergence of chemical signals released by plants that could be acting to ensure that ants are able to recognize and defend epiphyte species frequently associated with AGs. In this study, it was hypothesized that ants recognize and differentiate among chemical stimuli released by AG epiphytes and non-AG epiphytes. We experimentally simulated leaf herbivore damage on three epiphyte species restricted to AGs and a locally abundant understory herb, Piper hispidum, in order to quantify the number of recruited Camponotus femoratus (Fabricius) defenders. When exposed to the AG epiphytes Peperomia macrostachya and Codonanthe uleana leaves, it was observed that the recruitment of C. femoratus workers was, on average, respectively 556% and 246% higher than control. However, the number of ants recruited by the AG epiphyte Markea longiflora or by the non-AG plant did not differ from paper pieces. This indicated that ants could discern between chemicals released by different plants, suggesting that ants can select better plants. These results can be explained by evolutionary process acting on both ants' capability in discerning plants' chemical compounds (innate attraction) or by ants' learning based on the epiphyte frequency in AGs (individual experience). To disentangle an innate behavior, a product of classical coevolutionary process, from an ant's learned behavior, is a complicated but important subject to understand in the evolution of ant-plant mutualisms.

  14. Experimental evidence for the ectodermal origin of the epithelial anlage of the chicken bursa of Fabricius.

    The bursa of Fabricius (BF) is a central lymphoid organ of birds responsible for B-cell maturation within bursal follicles of epithelial origin. Despite the fundamental importance of the BF to the birth of B lymphocytes in the immune system, the embryological origin of the epithelial component of the BF remains unknown. The BF arises in the tail bud, caudal to the cloaca and in close association with the cloacal membrane, where the anal invagination (anal sinus) of ectoderm and the caudal endodermal wall of the cloaca are juxtaposed. Serial semi-thin sections of the tail bud show that the anal sinus gradually transforms into the bursal duct and proctodeum, which joins the distal part of the cloaca during late embryogenesis. These anatomical findings raise the possibility that the ectoderm may contribute to the epithelial anlage of the BF. The expression of sonic hedgehog and its receptor in the embryonic gut, but not in the BF, further supports an ectodermal origin for the bursal rudiment. Using chick-quail chimeras, quail tail bud ectoderm was homotopically transplanted into ectoderm-ablated chick, resulting in quail-derived bursal follicle formation. Chimeric bursal anlagen were generated in vitro by recombining chick bursal mesenchyme with quail ectoderm or endoderm and grafting the recombination into the chick coelomic cavity. After hematopoietic cell colonization, bursal follicles formed only in grafts containing BF mesenchyme and tail bud ectoderm. These results strongly support the central role of the ectoderm in the development of the bursal epithelium and hence in the maturation of B lymphocytes.

    The mitotic index in the cortical compartment of the follicles of the bursa of Fabricius from chicks immunized with sheep red blood cells (SRBC) is always higher when compaired with non-immunized ones. This mitotic index reachs its maximum 6 days after the SRBC injection, coincident with the highest serum antibody titer. The mitotic activity in the cortex of the follicles of the bursa of Fabricius is always higher than that of the medulla during the postembryonic development of chickens (PROCHAZKA, RODAK, KREJCI 1967). Otherwise it is almost established that the cortex is a zone of continuous lymphocyte proliferation, not occuring the same with the medulla. In addition these bursal histological structures are considered as 2 distinct compartments (GROSSI et al. 1974). The purpose of this paper is to study the response in the mitotic index of the cortical and medullary compartments of the follicles of the bursa of immunized and non-immunized chicks. To correlate possible changes in the mitotic index with circulating antibody levels, the serum antibody titer from the same birds was also recorded.

    Full Text Available The aim of the thesis was to investigate life cycle, biological and morphological characteristics of pear shoot sawfly (Janus compressus Fabricius, Hymenoptera Cephidae, furthermore to identify natural enemies in order to protect pear from this pest. The trial was conducted in the period of three years: 2010, 2011 and 2012 in pear orchards at five localities. Monitoring of adult sawfly was done by yellow sticky traps. Laboratory research was done at the Faculty of Agriculture, Department of Plant Protection, Section of Entomology and Nematology. In this study, pear shoot sawfly in Eastern Slavonia occurred in the period of four weeks, starting from the third decade of April with the peak population at the beginning of the May. Adults flight is the most intensive during warm and sunny days, when temperatures are above 14°C. Adult sawflies are characterized by elongated body and antennae, usually 7-12 mm long and sexual dimorphism is present. Pest is univoltine. Basic colour of adult sawfly is black. Antennae are moniliform and consist of 20 (male - 22 (female segments. Females have red or dark red colored abdomen, while males have yellow or orange one. Eggs are cylindrically shaped, 0.8-1.0 mm long. Female lays approximately 30 eggs. Embryonic development of pear shoot sawfly eggs lasts from 11 to 14 days. Larvae are 8-10 mm long, white or pale yellow. Larvae molt three times. Pear shoot sawfly larvae were parasitized by insects from Hymenoptera order, from five identified and one unidentified genera. Level of parasitism by genera is as follows: Eurytoma sp. (Hymenoptera: Eurytomidae – 9.83%, Tetrastichus sp. (Hymenoptera: Eulophidae – 2.01%, Eupelmus sp.

    Abstract. The ability of the parasitoid to locate and parasitize the host is directly related to the success of biological control of pests. The effect of Cotesia flavipes Cameron’s age on the ability to quest and parasitism larvae of Diatraea saccharalis (Fabricius in laboratory conditions was evaluated. An amount of 2,000 adults (24 hours aged was released. Fourteen sugarcane borer artificially infested internodes were 5 and 10 m placed apart each other, comprising eighteen stalks in each evaluation, during six days. The higher parasitism rate was observed in the first day after parasitoid release, with significant differences from the fifth day on. Therefore, C. flavipes is able to efficiently parasitize until its first 120 hours of life in laboratory conditions. It makes possible a recommendation of 24-hours aged parasitoid releases, that possibly will be more efficient in the sugarcane borer biological control.

    This study investigated the influence of paraquat, a prevalent poison used by suicides, on initial oviposition and development of Chrysomya megacephala (Fabricius) using minced-beef substrates. Paraquat in lethal dose for human (40 mg/kg), two times the lethal dose (80 mg/kg) and five times the lethal dose (200 mg/kg) were mixed thoroughly with respective minced-beef substrates (1 kg each) that were decomposed in a shaded habitat fully protected from rain. Results of four replications of the above experiment revealed that the presence of paraquat neither delayed initial oviposition nor prolonged the developmental stages of C. megacephala. Therefore, estimation of postmortem interval (PMI) based on empirical baseline data obtained using animal models devoid of any poisons would still be appropriate for estimating PMI in paraquat-related deaths.

    Full Text Available Defensive behavior associated with secretions from the prosternal paired glands of the larvae of Heliconius erato phyllis Fabricius (Lepidoptera, Nymphalidae. Our work presents for the first time, the defensive behavior associated with the release of the product of the prosternal paired glands of the larva of Heliconius erato phyllis Fabricius, 1775 (Lepidoptera, Nymphalidae, Heliconiinae. The prosternal glands were first described for larvae of H. erato phyllis. They are formed by two types of glandular structures: the impair gland and the paired glands. The prosternal glands are located within the conical integumentary sac, which in turn is situated on the individual's prosternum. The main goal of this study is to analyze the existence of any secretion from the prosternal paired glands, and check the action mode of this secretion. The methodology used for chemical analysis of the glands included the aeration and, analysis in gas chromatography and gas chromatography-mass spectrometry. The results show that the prosternal glands do not produce volatiles. Bioassays were conducted with simulated and natural attacks and revealed that the prosternal paired glands produce secretions of defense together with silk produced by labials glands as a defense strategy, described for the first time, against ants. The strategy consists in wrapping the ant with silk threads, the entire wrapped object moved to the end of the body, with the aid of the legs and prolegs, and possibly fixed in a nearby place. Evidence for the existence of a conical integumentary sac in larvae of other species and families of Lepidoptera allows us to propose the possibility of occurrence of prosternal paired glands with defensive function in these other groups as well.

    Eurasian harvestmen have been introduced to, and have established themselves in North America. Species known to have been introduced include Trogulus tricarinatus (L.) 1767, Paroligolophus agrestis (Meade) 1855, Rilaena triangularis (Herbst) 1799, Oligolophus tridens (C. L. Koch) 1836, and Nemastoma bimaculatum (Fabricius) 1775, for the last of which new Canadian records (Ontario) are given below. It is not entirely determined if the species Phalangium opilio (L.) 1758, Opilio parietinus (DeGeer) 1778 and Mitopus morio (Fabricius) 1779 are introduced to North America, or are naturally of Holarctic distribution. The former seems the more likely hypothesis for the first two, but M. morio in North America may be native or may not be that species. Detailed descriptions and illustrations of all these species may be found in Martens (1978).

    Full Text Available Adults and larvae of Leptotrachelus dorsalis (Fabricius, the Sugarcane Savior Beetle, live in association with grasses, the larvae in the appressed leaf axils. Both adult and larval L. dorsalis eat larvae of the Sugarcane Borer, Diatraea saccharalis (Fabricius, and perhaps other insects living in the confines of the leaf sheaths of that and other grass-like species. The geographic range of L. dorsalis extends from Kansas in the west to the Atlantic seaboard, north as far as Ontario, Canada and south to Cuba; it is an eastern species of North America and the Caribbean. Larval character attributes that are shared with a related ctenodactyline, Askalaphium depressum (Bates, provide a preliminary basis for characterization of the immatures of tribe Ctenodactylini.

    This study was to investigate the expression trait of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) gene and the effect of cold stress on the mRNA levels of PPAR-gamma in spleen, thymus, and bursa of Fabricius of chickens. Eighty-four 1-d-old male chickens were randomly allocated to 12 groups (7 chickens per group). There was 1 control group and 5 treatment groups for acute cold stress and 3 control groups and 3 treatment groups for chronic cold stress. Chickens were maintained in our animal facility, kept under a 16L:8D cycle and temperature (30 +/- 2 degrees C), and given free access to standard chow and water. The cold stress was initiated when the birds were 15 d of age, with the duration of the acute cold stress being 1, 3, 6, 12, and 24 h, and the chronic cold stress was 5, 10, and 20 d, respectively. Cold stress temperature was 12 +/- 1 degrees C. Spleen, thymus, and bursa of Fabricius were collected for the assessment of the mRNA levels by real-time PCR after stress termination. The results showed that the PPAR-gamma gene is expressed in spleen, thymus, and bursa of Fabricius, and its expression level is different in different tissues and at different ages. Acute cold stress significantly decreased (P stress resulted in a significant increase (P stress applied and also varies by tissue.

    Full Text Available The effects of T-2 toxin and zearalenone were studied in black tiger shrimp (Penaeus monodon Fabricius. In the experiment, black tiger shrimp were fed with different concentrations of T-2 toxin, i.e. 0, 0.1, 1.0 and 2.0 ppm and zearalenone, i.e. 0, 0.1. 0.5 and 1.0 ppm. Shrimp with initial average weight of 4.7 g were experimented for a-10-wk period. Supplementation of 0, 0.1 and 1.0 ppm T-2 produced no histological changes in hepatopancreatic, hemopoietic tissue or lymphoid cell while at higher concentration of 2.0 ppm atrophy, severe necrosis and degeneration of hepatopancreatic tubules, loose contact of hemopoietic tissue and lymphoid organ occurred. Similar observations were noted for the treatments with 0.5 and 1.0 ppm zearalenone - supplemented feed. Histological changes were, however, observed in hepatopancreatic tissue. The scale of histological changes correlated with feeding period and concentrations of zearalenone shrimp received.

    Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was assessed. For each worker size category olfactory responses to Dufour gland extracts were determined using electroantennography (EAG). Gas chromatography and mass spectrometry (GC-MS) were used to determine the chromatographic profile of Dufour gland secretion for each worker size. Morphometric measures permitted to classify the workers of S. geminata as large, medium and small workers. Medium S. geminata workers displayed a significantly higher behavioral response to Dufour gland extracts produced by medium size workers. Similarly, medium workers showed a significantly higher EAG response to Dufour gland extracts produced by medium sized workers. Chromatographic profile of Dufour gland secretions produced by workers showed that each size category exhibited a characteristic profile of the three main components considered as potential trail pheromone constituents. This work showed that medium workers of S. geminata exhibited a high trail-following behavior as well as a high antennal response to Dufour gland secretion. This and their relative abundance in field foraging areas, suggest that medium-sized workers are specialized in foraging activities. (author)

    Full Text Available Of major importance in realizing the potential of edible insects as a core element in improving food security, sustainable food production, and biodiversity conservation, are developments in sustainable exploitation of wild edible insect populations and in (semi-cultivating and farming edible insects. Such developments can draw on both western science and indigenous knowledge. Oecophylla smaragdina Fabricius Hymenoptera: Formicidae, of which particularly the queen brood is commonly consumed in Thailand and the Lao PDR, is believed to have the potential to act as flagship/umbrella species in forest conservation and management, to be incorporated simultaneously as biological control agent and direct source of human food in agroforestry practices, and to be (semi-cultivated. We provide a detailed account of indigenous knowledge of O. smaragdina and ant brood collection practices from the Vientiane Plain, Lao PDR, through focus group discussions and participant observations, and then reflect on sustainability and conservation issues, and on semi-cultivating constraints and possibilities embedded in indigenous knowledge and ant brood collection practices.

    Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabricius larvae was investigated by exposing S. litura larvae to the artificial diets amended with different doses of nickel for 3 generations. Nickel accumulations in the midgut of 6th instar larvae were detected by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the induced metallothionein expression in the midgut of 5th and 6th instar larvae in 120 h were quantified using cadmium-hemoglobin total saturation methods. The accumulated nickel in the midgut of the 6th instar larvae within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependence with the nickel doses in diets. Metallothioneins induced by nickel accumulated in the larval midgut also increased with nickel doses in diets and with the increasing stressing time in a generation. Results also suggested that the metallothionein expression was different with the time of S. litura larvae stressed by nickel.

    The artificial diets mixed with various concentrations of nickel were offered to the larvae of the phytophagous insect Spodoptera litura Fabricius for 3 generations. Nickel accumulations in the 6th instar larvae, pupae and newly emerged adults of the corresponding generations of S. litura were investigated by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the effects of nickel accumulations on the survival rate of S. litura were also evaluated by individual rearing. The results showed that nickel accumulated in the 6th instar larvae, pupae and adults of S. litura, and the accumulated nickel in all the tested developmental stages within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependent relationship with the nickel doses in the artificial diets. The results also indicated that the nickel accumulations in the 6th instar larvae, pupae, and newly emerged adults from the 3rd generation were higher than those from the 2nd generation, which were also higher than those from the 1st generation. Nickel concentrations in pupae and adults were significantly lower than those in larvae, which indicated that the excessive nickel might be excreted during metamorphosis. Furthermore, larval survival rate, pupation rate and eclosion rate of S. litura in the tested three generations all decreased with the increase of the nickel doses in the treated diets.

A biologia e o comportamento de P. nucleorum em A. arenaria e as taxas de predação de sementes foram descritas. Frutos encontrados sob 50 palmeiras foram coletados, mensalmente, em cada uma das duas áreas amostradas no PNRJ (mata de cordão arenoso e formação arbustiva aberta de Clusia Sclthdl, Clusiaceae. A avaliação dos cocos predados foi feita a partir da contagem dos orifícios de saída dos bruquíneos no campo, da emergência dos insetos no laboratório e da abertura dos frutos remanescentes. Através de observações e experimentos em 60 infrutescências, verificou-se que a oviposição de Pachymerus nucleorum em A. arenaria ocorre na infrutescência ainda em desenvolvimento diferentemente de registros na literatura em outras espécies de palmeiras, onde a oviposição ocorre nos frutos no chão. A predação dos frutos por P. nucleorum foi de 29,3% na área de mata de cordão arenoso e 20,6% na formação arbustiva aberta de Clusia.

    Full Text Available Megabunus diadema (Fabricius, 1779 is an Atlantic and European harvestman species characterized by a discontinuous distribution from Scandinavia to the Iberian Peninsula. With very few male individuals ever observed in the field until now, the biological uniqueness of the species lies in its reproduction mode, hitherto regarded as asexual, facultative parthenogenesis. Based on a large sample of 741 sexed individuals, the study indicates a sex ratio much higher than what was formerly known, equal to 65.58% of males. Locally varying from 0 to 100% (median 75.5% of males, the sex ratio depends indeed on the altitude and the phenological cycle: the proportion of males decreases with increasing altitude and increases gradually during the spring to reach a plateau in summer. By describing populations locally dominated by male individuals and providing new information on the spatial and temporal patterns of tertiary sex ratio, we question the currently admitted reproduction mode of the species which could be normally sexual, at least locally, rather than asexual. A distribution map of the species on the northern slope of the Pyrenees is provided for the first time. Our study also complements the distribution for the southern slopes of the Pyrenees and the rest of the Iberian Peninsula published recently by Merino-Sáinz et al.

    Full Text Available Abstract Background Two-dimensional gel electrophoresis (2-DE is a powerful method to study protein expression and function in living organisms and diseases. This technique, however, has not been applied to avian bursa of Fabricius (BF, a central immune organ. Here, optimized 2-DE sample preparation methodologies were constructed for the chicken BF tissue. Using the optimized protocol, we performed further 2-DE analysis on a soluble protein extract from the BF of chickens infected with virulent avibirnavirus. To demonstrate the quality of the extracted proteins, several differentially expressed protein spots selected were cut from 2-DE gels and identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS. Results An extraction buffer containing 7 M urea, 2 M thiourea, 2% (w/v 3-[(3-cholamidopropyl-dimethylammonio]-1-propanesulfonate (CHAPS, 50 mM dithiothreitol (DTT, 0.2% Bio-Lyte 3/10, 1 mM phenylmethylsulfonyl fluoride (PMSF, 20 U/ml Deoxyribonuclease I (DNase I, and 0.25 mg/ml Ribonuclease A (RNase A, combined with sonication and vortex, yielded the best 2-DE data. Relative to non-frozen immobilized pH gradient (IPG strips, frozen IPG strips did not result in significant changes in the 2-DE patterns after isoelectric focusing (IEF. When the optimized protocol was used to analyze the spleen and thymus, as well as avibirnavirus-infected bursa, high quality 2-DE protein expression profiles were obtained. 2-DE maps of BF of chickens infected with virulent avibirnavirus were visibly different and many differentially expressed proteins were found. Conclusion These results showed that method C, in concert extraction buffer IV, was the most favorable for preparing samples for IEF and subsequent protein separation and yielded the best quality 2-DE patterns. The optimized protocol is a useful sample preparation method for comparative proteomics analysis of chicken BF tissues.

    Nickel is an environmental pollutant that adversely affects the male reproductive system. In the present study, the effects of nickel exposure on Spodoptera litura Fabricius were investigated by feeding larvae artificial diets containing different doses of nickel for three generations. Damage to testes and effects on male reproduction were examined. The amount of nickel that accumulated in the testes of newly emerged males increased as the nickel dose in the diet increased during a single generation. Nickel exposure increased the amount of thiobarbituric acid reactive substances and decreased the amount of glutathione in treatment groups compared with the control. The activity levels of the antioxidant response indices superoxide dismutases, catalase, and glutathione peroxidase in the testes showed variable dose-dependent relationships with nickel doses and duration of exposure. Nickel doses also disrupted the development of the testes by decreasing the weight and volume of testes and the number of eupyrene and apyrene sperm bundles in treatment groups compared with the control. When the nickel-treated males mated with normal females, fecundity was inhibited by the higher nickel doses in all three generations, but fecundity significantly increased during the second generation, which received 5 mg kg(-1) nickel. Hatching rates in all treatments significantly decreased in a dose-dependent manner in the three successive generations. The effects of nickel on these parameters correlated with the duration of nickel exposure. Results indicate assays of testes may be a novel and efficient means of evaluating the effects of heavy metals on phytophagous insects in an agricultural environment.

    The Artocarpus fruit fly, Bactrocera umbrosa (Fabricius) (Diptera: Tephritidae), is an oligophagous fruit pest infesting Moraceae fruits, including jackfruit (Artocarpus heterophyllus Lamarck), a fruit commodity of high value in Malaysia. The scarcity of fundamental biological, physiological and ecological information on this pest, particularly in relation to behavioural response to phytochemical lures, which are instrumental to the success of many area-wide fruit fly control and management programmes, underpins the need for studies on this much-underrated pest. The positive response of B. umbrosa males to methyl eugenol (ME), a highly potent phytochemical lure, which attracts mainly males of many Bactrocera species, was shown to increase with increasing age. As early as 7 days after emergence (DAE), ca. 22% of males had responded to ME and over 50% by 10 DAE, despite no occurrence of matings (i.e. the males were still sexually immature). Male attraction to ME peaked from 10 to 27 DAE, which corresponded with the flies' attainment of sexual maturity. In wind-tunnel assays during the dusk courtship period, ME-fed males exhibited earlier calling activity and attracted a significantly higher percentage of virgin females compared with ME-deprived males. ME-fed males enjoyed a higher mating success than ME-deprived males at 1-day post ME feeding in semi-field assays. ME consumption also promotes aggregation behaviour in B. umbrosa males, as demonstrated in wind-tunnel and semi-field assays. We suggest that ME plays a prominent role in promoting sexual communication and enhancing mating performance of the Artocarpus fruit fly, a finding that is congruent with previous reports on the consequences of ME acquisition by other economically important Bactrocera species.

    Insect specimens collected from decomposing bodies enable forensic entomologists to estimate the minimum post-mortem interval (PMI). Drugs and toxins within a corpse may affect the development rate of insects that feed on them and it is vital to quantify these effects to accurately calculate minimum PMI. This study investigated the effects of morphine on growth rates of the native Australian blowfly, Calliphora stygia (Fabricius) (Diptera: Calliphoridae). Several morphine concentrations were incorporated into pet mince to simulate post-mortem concentrations in morphine, codeine and/or heroin-dosed corpses. There were four treatments for feeding larvae; T 1: control (no morphine); T 2: 2 microg/g morphine; T 3: 10 microg/g morphine; and T 4: 20 microg/g morphine. Ten replicates of 50 larvae were grown at 22 degrees C for each treatment and their development was compared at four comparison intervals; CI 1: 4-day-old larvae; CI 2: 7-day-old larvae; CI 3: pupae; and CI 4: adults. Length and width were measured for larvae and pupae, and costae and tibiae were measured for adults. Additionally, day of pupariation, day of adult eclosion, and survivorship were calculated for each replicate. The continued presence of morphine in meat was qualitatively verified using high-performance liquid chromatography with acidic potassium permanganate chemiluminescence detection. Growth rates of C. stygia fed on morphine-spiked mince did not differ significantly from those fed on control mince for any comparison interval or parameter measured. This suggests that C. stygia is a reliable model to use to accurately age a corpse containing morphine at any of the concentrations investigated.

    Full Text Available ABSTRACT. Chrysomya albiceps (Wiedemann and Hemilucilia segmentaria (Fabricius (Diptera, Calliphoridae used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819 emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805 were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case.

    Full Text Available In this paper, two methods for assessing the degree of melanization of pupal exuviae from the butterfly Heliconius erato phyllis , Fabricius 1775 (Lepidoptera, Nymphalidae, Heliconiini are compared. In the first method, which was qualitative, the exuviae were classified by scoring the degree of melanization, whereas in the second method, which was quantitative, the exuviae were classified by optical density followed by analysis with appropriate software. The heritability (h 2 of the degree of melanization was estimated by regression and analysis of variance. The estimates of h 2 were similar with both methods, indicating that the qualitative method could be particularly suitable for field work. The low estimates obtained for heritability may have resulted from the small sample size ( n = 7-18 broods, including the parents or from the allocation-priority hypothesis in which pupal color would be a lower priority trait compared to morphological traits and adequate larval development.

    The bursa of Fabricius (BF) is the central humoral immune organ unique to birds which plays important roles in B lymphocyte differentiation. Here, a new bursal peptide (BP11) with the amino acid sequence DVAGKLPDNRT was identified and characterized from BF. It was proved that BP11 promoted CFU pre-B formation, and regulated B cell differentiation, including increase the percentage of immature and mature B cells in BM cells co-cultured with IL-7. BP11 also exerted immunomodulatory function on antigen-specific immune responses in BALB/c mice immunized with inactivated influence virus (AIV, H9N2 subtype) vaccine, including enhancing AIV-specific antibody and cytokine production. Furthermore, it was noteworthy that BP11 stimulated antibody productions and potentiates the Th1 and Th2-type immune responses in dose-dependent manner in chicken. These results suggested that BP11 might be highly relevant for the development of avian immune system.

    Full Text Available Diaphorina citri Kuwayama (Hemiptera: Psyllidae is the vector of citrus greening (Huanglongbing bacterium and the most serious impediment to citrus culture. Classical biological control of this psyllid vector should contribute to suppress their population. This research was conducted to determine the performance of Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae when they were fed with D. citri. The larval performance index of M. sexmaculatus on D. citri compared with Aphis craccivora Koch (Hemiptera: Aphididae diet was 1.3.M. sexmaculatus fed with D. citri had lower fitness than those fed with A. craccivora as shown by longer larval stadium, lower adult dry weight, less number of egg produced and lower percentage of egg hatched. M. sexmaculatus grew best at the temperature of 27oC. Employing the exclusion procedure under field condition,M. sexmaculatus could reduce the population of D. citri up to 90%. These findings showed that theM. sexmaculatus could be a potential predator in reducing D. citri, particularly when the more preferred prey A. craccivora was not present.   Diaphorina citri Kuwayama (Hemiptera: Psyllidae merupakan kelompok Psyllid yang menularkan penyebab penyakit Huanglongbing yang sangat berbahaya pada tanaman jeruk.

    Abstract. Trichogramma species are an important group of parasitoids that attack especially lepidopteran eggs. The quality and performance of this natural enemy may be influenced by factors such as alternative host used in the massal rearing, and differences in the temperature and photoperiod. Based on this, this study aimed to evaluate the number of parasitized eggs, % of females that parasitized, % emergence, sex ratio and number of individuals of Trichogramma galloi Zucchi per egg of Diatraea saccharalis (Fabricius in the presence and absence of light. The experimental design was completely randomized with two treatments (light and dark and 60 replications, being each experimental unit composed by 40 eggs of D. saccharalis which were placed in a glass tube with one female of T. galloi with age of 24 hours, previously fed with honey. The experiment was carried out at 25 ± 2 °C and 70 ± 10% relative humidity. In each one of the treatments, the parasitoid was removed from the tube after 12 hours. The highest number of parasitized eggs (12.9 and % of females that parasitized (83.3% was observed during the period with light. For the emergence, sex ratio and number of individuals per egg, there was no statistical difference. The results showed that the presence of light is essential for this biological control agent.

    Some beetles are as useful as blow flies for estimating the minimum post mortem interval (PMImin) or time since death. Examples include Thanatophilus micans (Fabricius) and Thanatophilus mutilatus (Castelneau), two geographically and ecologically overlapping African beetles. Molecular means of identifying these species, descriptions of their natural history, thermal summation models for the development of each species, and a case in which T. micans was recovered are presented. These beetles colonise bodies soon after death, their development spans more time than that of flies, and they may be little affected by maggot-generated heat. From an experimental perspective, they can be reared individually, which allows the identification of sick individuals and has analytical advantages relative to fly larvae that must be reared in groups. Estimating minimum post mortem intervals for both species using the case data strongly suggests that developmental models parameterised for one species should not be used to make forensic estimates for closely related species for which no specific model is available and emphasises the need for correct identifications.

    Ninety six yeastisolates associated with dung beetles (Heliocopris bucephalus Fabricius) were examined based on culture-dependent method. A comparison of the colony morphology and PCR fingerprints obtained by (GTG)5microsatellite-primed PCR indicated that 84 of these isolates belonged to one group. Five strains (DD1-1,DD2-33, DD4-11, DD5-15 and DD6-1) were selected as the representatives of this main group, whereeach of the five selectedstrains had been derivedfrom a different dung beetle collected innorthern Thailand. A comparison of the D1/D2 domain sequence of the large subunit rRNA gene (LSU D1/D2) and the internal transcribed spacer (ITS) sequencesrevealed that these five strains were the same and wererelated to the genus Trichosporon. Phylogenetic analysis based on the LSU D1/D2 plusITSsequences placed this group within the Trichosporonbrassicae clade, but it was clearly separated from any known species. In addition, physiological tests showed that this group had the unusual property of the inability to hydrolyze urea, which was distinctly different from the related taxon. Therefore, Trichosporon heliocopridis sp. nov. (ex-type strainDD1-1T = TISTR 5946T = JCM 30786T = CBS 14168T) is proposed as a novel yeast species. The MycoBank number is MB812098.

    Full Text Available The sublethal effects of diazinon, fenitrothion and chlorpyrifos on the functional response of predatory bug, Andrallus spinidens Fabricius (Hem.: Pentatomidae, a potential biological control agent, were studied on 5th-instar nymphs. The experiment was conducted in varying densities (2, 4, 8, 16, 32 and 64 of last instars larvae of Chilo suppressalis Walker (Lepidoptera: Pyralidae as prey at 25 ± 2 °C, 60% ± 10% relative humidity (RH and a photoperiod of 16:8 h (L: D. The results of logistic regressions revealed a type II functional response in the control and all insecticide treatments. Comparison of functional response curves revealed that tested insecticides markedly decreased the mean of preys consumed by A. spinidens. Among them, functional response curve of A. spinidens in chlorpyrifos treatment was significantly lower than the other treatments. In this study, application of insecticides caused a decrease in the attack rate and an increase in the handling time of exposed bugs compared with the control. The longest handling time (3.97 ± 0.62 and the lowest attack rate (0.023 ± 0.007 were observed in chlorpyrifos and fenitrothion treatments, respectively. The results suggested that the adverse effect of these insecticides on A. spinidens should be considered in integrated pest management programs (IPM.

    Previous studies on the legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), a serious pest of cowpea, Vigna unguiculata (L.) Walp. (Fabales: Fabaceae), in sub-Saharan Africa have focused on sex pheromones, but the role of the host plant on sexual behavior has not been explored. We investigated this interaction in the laboratory using behavioral assays and chemical analyses. We found that the presence of cowpea seedlings and a dichloromethane extract of the leaf increased coupling in the legume pod borer by 33 and 61 %, respectively, compared to the control, suggesting the involvement of both contact and olfactory cues. We used coupled gas chromatography-electroantennographic detection (GC/EAD) and GC-mass spectrometry (GC/MS) to identify compounds from the cowpea leaf extract, detected by M. vitrata antenna. We found that the antennae of the insect consistently detected four components, with 1-octen-3-ol identified as a common and dominant component in both the volatiles released by the intact cowpea plant and leaf extract. We therefore investigated its role in the coupling of M. vitrata. In dose-response assays, 1-octen-3-ol increased coupling in M. vitrata with increasing dose of the compound compared to the control. Our results suggest that the cowpea volatile 1-octen-3-ol contributes to M. vitrata sexual behavior.

    Recently (2013-2014), several hoverfly specimens from two localities in Benin and Cameroon (West and Central Africa) were caught from a species that we could not identify using existing identification keys for Afrotropical Syrphidae. Specific identification as Toxomerus floralis (Fabricius) was accomplished using morphology and various Neotropical identification keys. Corroboration of this identification was made by sequencing of the standard COI barcode region and a subsequent BLAST-IDS in BOLD that revealed a 100% sequence similarity with Toxomerus floralis from Suriname (South America). Species identification was further supported by sequencing parts of the nuclear 18S and 28S rRNA genes. The species is widespread in Togo, Benin, Nigeria and Cameroon, and eggs, larvae and adults are abundant at several localities. Yet, the full extent of its geographic distribution within tropical Africa remains to be determined. This is only the second known established introduction of a non-African hoverfly species in the Afrotropics. Interestingly, the larvae of the species have been reported as predators of Aphididae and Delphacidae but we found them to be pollenivorous, which is a rare feeding mode within the subfamily Syrphinae. Moreover, it is the only known Syrphinae species of which the larvae feed on pollen from two plant species from different families (Cyperaceae and Orobranchaceae). This example illustrates how DNA barcoding may allow a fast and accurate identification of introduced species.

    Full Text Available ABSTRACT Among the options to control Alabama argillacea (Hübner, 1818 and Heliothis virescens (Fabricius, 1781 on cotton, insecticide spraying and biological control have been extensively used. The GM'Bt' cotton has been introduced as an extremely viable alternative, but it is yet not known how transgenic plants affect populations of organisms that are interrelated in an agroecosystem. For this reason, it is important to know how the spatial arrangement of pests and beneficial insect are affected, which may call for changes in the methods used for sampling these species. This study was conducted with the goal to investigate the pattern of spatial distribution of eggs of A. argillacea and H. virescens in DeltaOpalTM (non-Bt and DP90BTMBt cotton cultivars. Data were collected during the agricultural year 2006/2007 in two areas of 5,000 m2, located in in the district of Nova América, Caarapó municipality. In each sampling area, comprising 100 plots of 50 m2, 15 evaluations were performed on two plants per plot. The sampling consisted in counting the eggs. The aggregation index (variance/mean ratio, Morisita index and exponent k of the negative binomial distribution and chi-square fit of the observed and expected values to the theoretical frequency distribution (Poisson, Binomial and Negative Binomial Positive, showed that in both cultivars, the eggs of these species are distributed according to the aggregate distribution model, fitting the pattern of negative binomial distribution.

    Full Text Available Oviposition site selection of Heliconius erato phyllis (Fabricius, 1775 (Lepidoptera, Nymphalidae was studied when size of and damage on shoots were variable in a natural population of Passiflora suberosa Linnaeus (Passifloraceae, and through sequential and simultaneous choice experiments performed under insectary conditions. Females showed marked oviposition preference for undamaged and largest shoots of P. suberosa. Eggs were mostly laid on the terminal buds of intact shoots under natural conditions. In simultaneous choice trials, females preferred to oviposit on shoots from which leaves (ten were removed but the terminal bud maintained to those where leaves were kept but the terminal bud was cut out. In sequential choice trials, they did not lay eggs on shoots from which the terminal bud was removed. Females preferred to oviposit on large to short intact shoots in both sequential and simultaneous choice trials. Females laid eggs preferentially on shoots with the greatest leaf area when most plants were intact in the field during early spring. Later in fall, when mostly large, old shoots were damaged or in a reproductive stage (less desirable for oviposition, oviposition intensity was highest on the shortest, youngest shoots of P. suberosa. Thus, females might rank these quality attributes higher than size while selecting shoots for oviposition. The consequences of ovipositing selectively on intact, large shoots of P. suberosa are discussed from the view point of H. erato phyllis larval performance.

    Full Text Available Chickpea (Cicer arietinum L., is an important pulse food. During storage this commodity is severely attacked bybean beetle Callosobruchus maculatus (Fabricius resulting losses in quantity and nutritional quality. Research studies onrelative resistance of 12 chickpea genotypes to the attack of C. maculatus during storage were carried out. The genotypesmost tolerant to bruchids comprised CH-52/02 and B-8/03, whereas, the most susceptible reactions were apparent inCH-86/02 and CC-117/00. The moderate pest incidence was observed in CH-28/02, CH-4/02, CH-32/02, CH-31/02, CH-9/02,CM-772/03, B-8/02 and CM-628/03 genotypes. The tolerant genotypes exhibited hard and wrinkled seed coat, dark browncolour and small size grain. These characteristics demonstrated a significant harmful effect to pest appearance and graindamage. The vulnerable genotypes had soft and smooth seed coat, white seed colour and bigger grain size that causedvulnerability to C. maculatus. Based on the present investigation, chickpea genotypes CH-52/02 and B-8/03 deserve specialconsideration and may be recommended for relatively longer storage to achieve the goal of long term and sustainable pestmanagement strategies.

    This study aimed to evaluate the comparative effects of aflatoxin-contaminated corn on the thymus and bursa of Fabricius (BF) in chickens by detecting histopathological lesions, cell cycle phase distribution and apoptosis. A total of 900 COBB500 male broilers were randomly allocated into five groups. The experiment lasted for six weeks and the five dietary treatments consisted of uncontaminated corn (control), 25% contaminated corn, 50% contaminated corn, 75% contaminated corn and 100% contaminated corn groups. The gross changes showed the decreased size of the thymus and BF, as well as the pale color of the BF in the broilers after aflatoxin contaminated diet exposure. There were more nuclear debris in the thymus and BF of birds in the 50%, 75%, and 100% contaminated corn groups, but the pathological impairments of the BF were more obvious than those of the thymus, which showed as more obvious lymphocyte depletion and the proliferation of reticulocytes and fibroblasts. At 21 days of age, the percentage of thymocytes and BF cells in the G2M phase was increased in a dose-dependent manner in the four AFB-contaminated corn groups. However, at 42 days of age, dietary AFB1 induced cell cycle perturbation at the G0G1 phase in thymocytes, but at the G2M phase in BF cells. The increased percentage of apoptotic cells in the thymus and BF were similarly observed in the AFB groups. According to these results, the severity of histopathological lesions may be correlated with the different sensitivity of the two central immune organs when exposed to AFB; different arrested cell cycle phases suggest that different mechanisms may be involved in the lesions of the thymus and BF, which need to be further researched.

    The European wasp, Vespula germanica (Fabricius) (Hymenoptera: Vespidae), is of Palaearctic origin, being native to Europe, northern Africa and Asia, and introduced into North America, Chile, Argentina, Iceland, Ascension Island, South Africa, Australia and New Zealand. Due to its polyphagous nature and scavenging behaviour, V. germanica threatens agriculture and silviculture, and negatively affects biodiversity, while its aggressive nature and venomous sting pose a health risk to humans. In areas with warmer winters and longer summers, queens and workers can survive the winter months, leading to the build-up of large nests during the following season; thereby increasing the risk posed by this species. To prevent or prepare for such unwanted impacts it is important to know where the wasp may be able to establish, either through natural spread or through introduction as a result of human transport. Distribution data from Argentina and Australia, and seasonal phenology data from Argentina were used to determine the potential distribution of V. germanica using CLIMEX modelling. In contrast to previous models, the influence of irrigation on its distribution was also investigated. Under a natural rainfall scenario, the model showed similarities to previous models. When irrigation is applied, dry stress is alleviated, leading to larger areas modelled climatically suitable compared with previous models, which provided a better fit with the actual distribution of the species. The main areas at risk of invasion by V. germanica include western USA, Mexico, small areas in Central America and in the north-western region of South America, eastern Brazil, western Russia, north-western China, Japan, the Mediterranean coastal regions of North Africa, and parts of southern and eastern Africa.

    Full Text Available Micraspis discolor (Fabricius (Coleoptera: Coccinellidae is a widely distributed coleoptera predator in southern Asia in rice ecosystem, and adult M. discolor feed on both rice pollen and soft-bodied arthropods. Bitrophic bioassay and tritrophic bioassay were conducted to evaluate the potential impact of Cry1Ac/Cry1Ab-expressing rice Huahui 1 and its non-transgenic counterpart Minghui 63 on fitness parameters of adult M. discolor. The results showed that the survival, and fecundity of this beetle' adults were not different when they fed on Bt rice or non-Bt rice pollen or Nilaparvata lugens (Stål reared on Bt rice or non-Bt rice. Toxicity assessment to ensure M. discolor adults were not sensitive to Cry1Ab or Cry1Ac protein independent from the pollen background, M. discolor adults were fed with an artificial diet containing Cry1Ac, Cry1Ab or both protein approximately 10 times higher concentration than in Huahui 1 rice pollen. No difference was detected for any of the life-table parameters tested between Cry protein-containing and pure diet. Artificial diet containing E-64 (N-(trans-Epoxysuccinyl-L-leucine 4-guanidinobutylamide was included as a positive control. In contrast, the pre-oviposition and fecundity of M. discolor were significantly adversely affected by feeding on E-64-containing diet. In both bioassays, the uptakes of Cry protein by adult M. discolor were tested by ELISA measurements. These results indicated that adults of M. discolor are not affected by Cry1Ab- or Cry1Ac-expressing rice pollen and are not sensitive to Cry protein at concentrations exceeding the levels in rice pollen in Huahui1. This suggests that M. discolor adults would not be harmed by Cry1Ac/Cry1Ab rice if Bt rice Huahui 1 were commercialized.

In the choice tests, most aphids settled on plants without surface waxes or on diet preparations which did not have surface waxes (the controls. When the concentration of the surface waxes was increased on one of the plants or surface waxes were increased in the diet preparation, the number of wandering aphids increased. Those aphids which did not wander were mainly on the waxless control plants or on the waxless diet preparations. Aphids did settle on those plants or on the diet preparations which had 100 and 1,000 μg · g-1 of surface wax. The aphids rarely settled on the diet preparations containing 10,000 μg ∙ g-1 of surface waxes. From these observations it appears that surface waxes can act as a feeding deterrent. Since aphids on plants with surface waxes, or aphids which settled on diet preparations with surface waxes, started to die earlier than aphids fed only the control plants or the control diet preparations, it is possible that the surface waxes had a toxic effect that led to early mortality. Thus, it can be said that the surface waxes caused feeding deterrence and had a toxic effect on the aphids.

The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.

    Full Text Available Aphids were the main winter-cereal problem in the 70’s in southern Brazil and it was necessary to use chemical control to avoid losses. Based in the weak performance of native parasites, 14 species of exotic parasites were introduced in 1978, and in 1984 the West of Paranà’s Biological Control Program was implanted. This program propitiated the reduction of the Aphid population as well as chemical applications in the field. However, no bibliographic study was found referring to the ecological aspects of the parasites nor about Aphid’s biological control in Western Paraná´s region wheat production motivating the development of this study. Week evaluations in 25 parcel of 25 m2 were performed where 100 wheat plants were collected, from which aphid and bugs were taken out. It was observed the presence of an Aphid specie, Sitobion avenae (Fabricius (Hemyptera: Aphididae, the primary parasite Aphidius colemani Viereck (Hymenoptera: Aphidiidae, and hyper parasitoids, and also the presence of predators. S. avenae population zenith occurred in the beginning of budding and bugs appeared a week after the aphids. Aphid control was considered efficient at 95% total parasitism. Population zenith of A. colemani occurred in the beginning of August, while hyper parasitoids zenith occurred the following week. Aphid population growth was significantly influenced by the air relative humidity, whereas parasite population was influenced by temperature and aphid population density.Os afídeos foram o principal problema dos cereais de inverno na década de 70, no Sul do Brasil, havendo necessidade de controle químico para evitar as perdas.

    Full Text Available Fifty Bursa of Fabricius (BF were examined by conventional optical microscopy and digital images were acquired and processed using Matlab® 6.5 software. The Artificial Neuronal Network (ANN was generated using Neuroshell® Classifier software and the optical and digital data were compared. The ANN was able to make a comparable classification of digital and optical scores. The use of ANN was able to classify correctly the majority of the follicles, reaching sensibility and specificity of 89% and 96%, respectively. When the follicles were scored and grouped in a binary fashion the sensibility increased to 90% and obtained the maximum value for the specificity of 92%. These results demonstrate that the use of digital image analysis and ANN is a useful tool for the pathological classification of the BF lymphoid depletion. In addition it provides objective results that allow measuring the dimension of the error in the diagnosis and classification therefore making comparison between databases feasible.Cinquenta Bursa de Fabrícius (BF foram examinadas através de microscopia óptica convencional e imagens digitais foram obtidas e processadas através do software Matlab® 6.5.

    Abstract. Some neotropical social wasps which are associated with some vertebrates and other insects like ants, and these interactions are reported for decades, but little is known about the presence of these in the Caatinga and Atlantic Forest. This study describes the first association's record between nests of Polybia rejecta (Fabricius wasp and Azteca chartifex Forel ants in the transition area of the Atlantic Forest and Caatinga in Rio Grande do Norte. The observations were in a private forest in Monte Alegre, from October 2009 to September 2014 through active search for colonies, use of ad libitum method, photography and collection of specimens with traceability. In the study area were found four active colonies and one abandoned of P. rejecta, all associated with nests of A. chartifex with approach of 20-30 cm. It was found that when the colony of P. rejecta was disturbed, they became aggressive towards the disturbance object, whereas the ants gathered in order to fend off a potential predators. These interactions appear to benefit wasps and ants, it is assumed that is possible that wasps attack ants's predators, whereas the ants attack the wasps's predators. This study corroborates the hypothesis that the association between the social wasps P. rejecta and A. chartifex ants is beneficial for both species, and probably the wasps are the most benefited, but also shows the non-exclusivity of this association for the biomes up then reported.

    The effects and changing patterns of UV-B on growth, development and reproduction of Sitobion avenae (Fabricius) were evaluated by establishing an age-specific life table of S. avenae exposed to UV-B for eight successive generations. The results revealed that the population degradation existed in the population of S. avenae after being raised for several generations in the experimental condition. Under the UV-B irradiation, the developmental duration (T) increased gradually with the increase of generations, while the intrinsic rate of increase (Rm) , net reproductive rate (R0) > finite increase rate (A) and population number tendency index (I) of S. avenae decreased until the third generations, then stable in the following generations. The developmental duration of the second, the third and the fourth instar nymph from F1 to F5 of S. avenae were delayed, while no significant difference was found in F7 generation. Additionally, under the condition of UV-B, the adult longevity, fecundity (F) and population number tendency index (I) decreased until the F3 generation and then increased or trended to stabilize thereafter. In conclusion, the effects of UV-B would be accumulated in the progeny. As the selective forces in the environment, UV-B inhibited the growth and propagation of S. avenae, however, the adaptation of S. avenae to stress was enhanced with the increase of generations. We also found that, the transform of phenotype from unwinged to winged S. avenae was significant in this study, which was related with that of the ecology parameters.%为评估紫外线UV-B对麦长管蚜Sitobion avenae (Fabricius)生长、发育和繁殖的影响,用中波紫外线(UV-B)连续照射8代麦长管蚜3、4龄若虫,并用特定年龄生命表方法对其后代生态学参数进行分析.结果显示,麦长管蚜在实验室条件下多代饲养,表现出明显的种群退化现象.在UV-B的影响下,随着世代的增加,麦长管蚜的内禀增长率(Rm)、净增值率(R0)

    Full Text Available Ammabris Kuzin (1954, a subgenus of Mylabris Fabricius, 1775, includes a small group of fenetically close species associated to semiarid zones and deserts of Northern Africa, Middle East and Central Asia. Mylabris boghariensis Raffray, 1873, one of the least known species, doubtfuly included within the subgenus Ammabris, is known only from its type locality in Algeria. In this study, following the examination of the holotype of M. boghariensis, we expand its morphological description and redefine its nostic traits, including a description of the male genitalia. We confirm the assignation of M. boghariensis to Ammabris. The study of a series of specimens from Northeastern Morocco, phenetically close to M. boghariensis, but clearley differentiable by its external morphological characters and male genitalia, allow us to describe them as a new species, Mylabris avilai sp. nov .We discuss the diagnostic traits of this new species and compare them with all other species of Ammabris. As a result of the comparative morphological study of six especies of Ammabris we discuss the complexity and variability of the characters defining the subgenus, and the taxonomic position of Mylabris sisymbrii Klug, 1834. This study allow us to conclude that the subgenus is morphologically heterogeneous and possibly paraphyletic, in need of a broad systematic revisión to stablish its morphological limits and species composition.El subgénero Ammabris Kuzin, 1954 agrupa a un pequeño conjunto de especies del género Mylabris Fabricius, 1775, fenéticamente afines entre sí y asociadas a zonas semiáridas y desérticas del norte de África, Oriente Próximo y Asia Central.

Walp. seeds was assessed under laboratory conditions in Akure, Nigeria. In the tests, 20 g of infested cowpea seeds were suspended in a piece of muslin cloth, over an amount of crushed bulb in a container with a tightly fitted lid. Adult emergence was completely prevented from freshly laid eggs of C. maculatus on cowpea seeds that was fumigated with 6.0 g or more of crushed bulbs of A. sativum. Such fumigated seeds were not holed at all. Other amounts of A. sativum tested (1.0, 2.0, 3.0, 4.0 and 5.0 g significantly reduced C. maculatus adult emergence from fumigated eggs and seed holing in comparison with the control. Crushed A. sativum was ineffective in preventing adult emergence from fumigated C. maculatus larvae in seeds. The fumigant effect of crushed A. cepa did not kill all C. maculatus eggs.

    To valuate the immune mechanism of Chinese herbal medicine for heated-stress chickens, the histological changes of the central immune organs were observed. A total of 120 healthy 88-day-old Isa Brown commercial laying chickens were randomly divided into six groups,three experimental groups (High,medium and low dose groups) and three control groups (High temperature, room temperature and Vc (5 mg/d) groups). In the experimental groups chickens were fed with the high dose (7. 5 mg/d), the medium dose (5 mg/d), or the low dose (2. 5 mg/d) of Chinese herbal medicine. On Days 88,91,95,and 97,the changes of lymphocyte in bursa of fabri-cius and thymus of chicken were examined. The bursa of fabricius and thymus tissue samples were processed routinely for paraffin embedding technique and stained with haematoxylin and eosin (H. E). The results showed that on Day 97,the lymphocytes in bursa of fabricius added with 7. 5 mg/d Chinese herbal medicine was significantly increased than that of the high temperature control group (P<0. 01), which are 84. 33 and 69. 81, respectively. The lymphocytes in bursa of fabricius of chicken added with 5 mg/d Chinese herbal medicine was 81. 61, significantly increased than that of high temperature control group (P<0. 05). The lymphocytes in thymus of the high dose and the medium dose groups were 95. 85 and 91. 40,higher than that of the high temperature control group (P<0. 01). This indicated that adding 7. 5 mg/d Chinese herbal medicine for heated-stress chickens significantly increased lymphocytes in bursa of fabricius and thymus of chicken and the higher concentration the better,which implies that the Chinese herbal medicine is useful for easing the effects of heat stress.%为了探讨热应激下中草药对鸡中枢免疫器官的作用机制,进行了鸡法氏囊、胸腺内淋巴细胞数量的动态观察.选择88日龄健康伊莎褐商品代蛋用雏鸡120只,随机分成6个组:3个试验组为中草药高(7.5mg/d)、中(5mg

    E. M. Pires

    Full Text Available Abstract Results obtained in studies can contribute to the advancement of science and innovative methods and techniques for developing practical activities. Reporting conditions that may restrict the implementation of research is critical to ensure the optimal development of further technical studies. The objective of this study was to assess the walking stability of R. dominica on a flat and smooth surface. The study was based on the determination of mortality, morphology and walking stability of the insect outside the grain mass, on a flat and smooth surface. Mortality of adults of this Coleoptera in conditions with and without food was similar, which explains the difficulty that this insect had for accessing the food source on the flat and smooth surface. The measurements of body length (BOL, width (BOW and height (BOH of R. dominica were compared with those of Tribolium castaneum (Coleoptera: Tenebrionidae, which showed good ability to walk in these conditions. This study indicated that the former presents lower BOL and BOW, and greater BOH than the second, and all these variables showed differences when analyzed simultaneously by means of the construction of multivariate morphometric indices (Width × Height, Length × Height and Height × Length × Width. These morphometric variables, together with the definition of the geometry most similar to the body shape, resulted in determination of the center of gravity (CG and static rollover threshold (SRTgeom for both species. Rhyzopertha dominica and T. castaneum presented CGs considered high and low, respectively, and together with the values obtained for SRTgeom, may justify that R. dominica can be considered a less stable species during movement, and presents greater risk of rollover on flat and smooth surfaces.

    [Objectives] We examined interactions between H. vigintioctopunctata and three isogenic tomato (Lycopersicon esculentum) genotypes with different jasmonic acid (JA) pathways. [Methods] The tomato genotypes were; suppressor of prosystemin-mediated responses2 (spr2) mutant plants, 35s prosystemin (35s) plants, and wild type (Wt) plants. Activity of protease inhibitors (PI) and lipoxygenase (LOX) and dynamic change in relative gene expression of the three kinds of enzymes were tested to study the defense signal pathway induced by H. vigintioctopunctata in tomatoes, and the role of jasmonic acid (JA) in the plant defense process. [Results] Major results were; activity and gene expression of PI and LOX in 35s type tomatoes were significantly higher than in the other two varieties whereas the spr2 type tomato had the lowest level of PI expression. Different periods of exposure to H. vigintioctopunctata showed that the highest PI and LOX activity occurred in 35s and wt type tomatoes 24 h and 6 h after infestation, respectively. There was no significant temporal change in enzyme activity in spr2 type tomatoes. There were no significant differences in PAL activity and relative gene expression in the three tomato varieties. In the process of feeding on plants by H. vigintioctopunctata, PAL activity initially increased then declined after 48 h. No significant changes in PAL activity and gene expression were observed in systemic leaves. PI and LOX were more sensitive to insect herbivory than PAL. [Conclution] 35s tomatoes are to a certain degree resistant to H. vigintioctopunctata and jasmonic acid (JA) plays a role in this resistance.%【目的】研究茉莉酸合成相关基因在番茄抗茄二十八星瓢虫 Henosepilachna vigintioctopunctata Fabricius 中的作用,探讨茉莉酸信号因子在植物防御过程中起到的作用。【方法】利用3种基因型番茄茉莉酸合成缺失突变体 spr2、茉莉酸合成过量表达体35s、野生型番茄 Wt

    The present study revealed differentially expressed genes responsive to azadirachtin A (Aza) in Spodoptera litura cell line through suppression subtractive hybridization. In the Aza-responsive SSH library, approximately 270 sequences represent 53 different identified genes encoding proteins with various predicted functions, and the percentages of the gene clusters were 26.09% (genetic information processing), 11.41% (cell growth and death), 7.07% (metabolism), 6.52% (signal transduction/transport) and 2.72% (immunity), respectively. Eleven clones homologous to identified genes were selected to be confirmed through quantitative real time polymerase chain reaction. Among the eleven clones validated, all but one transcript of lipase showed an increase in SL cell line collected from ETA, whereas the transcripts of other genes were lower in the SL cell line collected from ETA compared with that of UETA. These genes were considered to be related to the response of SL cell line to Aza. These will provide a new clue to uncover the molecular mechanisms of Aza acting on SL cell line.

  19. Differential habitat use by demographic groups of the redfinger rubble crab Eriphia gonagra (Fabricius, 1781

    LS Andrade

    Full Text Available The structurally diverse rocky shores along the northern coast of the state of São Paulo, Brazil, support a varied fauna and provide refuges for many organisms. Some of these environments allow for extensive microhabitats, among them the sand reefs formed by the polychaete Phragmatopoma lapidosa, which occupy much of this area. The beauty of the landscape attracts large numbers of tourists, who contribute to the damage to the sand reef colonies, causing an imbalance in the patterns of population distribution and of this ecosystem. We describe the structure and population biology of the redfinger rubble crab Eriphia gonagra, and investigated the differential occupation of the habitat by each demographic category of this species. Crabs were sampled monthly for two consecutive years on the rocky coast of Grande Beach, Ubatuba, São Paulo, during spring low tides. Sampling was carried out over an area of approximately 1200 m2, during two hours on the rock surface and another two hours on the sand reefs. A total of 1407 crabs were collected; 776 on the sand reef (SR and 631 on the rocky shore (RO. The majority of juvenile crabs inhabited the SR, while adult crabs were equally distributed in both microhabitats. This study showed that the SR is a natural nursery ground for the establishment of the early juvenile stages of E. gonagra, which use the reefs as a refuge and food resource. Many other organisms (mollusks, echinoderms, polychaetes etc. settle on the reefs, and these areas may be among the most important in maintaining benthic diversity in the region.

This is thefirst host record of a Gasteruptiidae in the Neotropical Region. The behavior of a G.brachychaetum female entering a host's nest is described as follows: an inquiline female hovered near the host's nest, landed and detected that a female of H. aff. guaraniticus was inside the nest, waited for the host female to fly out, entered backwards into the nest, remained there for almost six minutes, and then went out the nest. The development time of immature stages of G.brachychaetum varied between 16 and 299 days.

    Full Text Available We evaluated the prevalence, mean intensity and relative density of ticks in 467 wild birds of 67 species (12 families from forest and cerrado habitats at two protected areas of Minas Gerais, between March and September 1997. Ticks collected (n=177 were identified as larvae and nymphs of Amblyomma cajennense and four other species of Amblyomma. We report for the first time 28 bird species as hosts of the immature stages of A. cajennense, demonstrating the lack of host specificity of the larvae and nymphs. A. cajennense had 15% prevalence on birds, with a mean infestation intensity of 0.37 ticks per host sampled, and 2.5 ticks per infested bird. Prevalence varied in relation to host species, diet and between birds from forests at two successional stages. There were no differences in relation to host forest dependence, participation in mixed flocks of birds, and nest type constructed. A. cajennense is a species of medical and veterinary importance, occurring on domestic animals but is known little of its occurrence on wildlife.

    Two valid ant species, Camponotus rufipes and Camponotus renggeri, have recently been the subject of a broad discussion with reference to taxa synonymization. Both species are quite common among the Neotropical myrmecofauna and share some unique traits, such as the shape of the scape and the pilosity patterns of the tibiae and scapes. A single morphological trait can help distinguish these species; however, only a combination of different approaches can enlighten our view of the complex phylogenetic relationships prevailing in the different populations of these two taxa. Therefore, focusing on the taxonomic issues concerning these two species, a cytogenetic survey including 10 populations of C. rufipes and two populations of C. renggeri was performed. In order to better understand the extent of the relationship between C. rufipes and C. renggeri, two common Neotropical Camponotus species, C. atriceps and C. cingulatus were taken as outgroups. All four species of Camponotus that were studied had 2n = 40 chromosomes (4sm+34st+2t); however, the abundance of chromosome rearrangements observed, combined with several chromosome markers, suggest that C. rufipes and C. renggeri are two good distinct species although closely related. The already reported chromosome translocation 2n = 39 (1m+4sm+32st+2t) for C. rufipes has been found in different populations as in the unprecedented chromosome inversions found both in C. rufipes and in C. renggeri populations. Within the C. renggeri chromosome inversions, both the heterozygous state 2n = 40 (1m+3sm+34st+2t) and the homozygous state, 2n = 40 (2m+2sm+34st+2t) were identified. However, only heterozygous specimens for chromosome inversions were found among C. rufipes, with karyotype configurations distinct from those found in C. renggeri, with 2n = 40 (1m+4sm+34st+2t). None of the populations studied showed signs of mosaic individuals. With respect to rDNA clusters, the 18S rDNA seemed to be more restricted inside the genome, as C. renggeri showed four 18S rDNA clusters, whereas, C. rufipes, C. atriceps, and C. cingulatus showed only two clusters. The chromosome locations of the 5S rDNA clusters were pointed for the first time in Formicidae, and showed itself to be more widely spread over the genome. By combining different chromosome banding approaches it was possible to demonstrate the crucial importance that chromosome inversions played on the karyotype evolution within these ants. The results also showed that chromosome translocations might be a consequence of the chromatin dynamic condition observed among Camponotus species. The homozygosis condition found in a C. renggeri from a Brazilian savanna population for chromosome inversions and the contrasting heterozygous condition for a different kind of chromosome inversion in C. rufipes from the Brazilian coastal rainforest, opens the window for a chromosome race hypothesis within the group C. renggeri and C. rufipes. The wide distribution, rich ecological interactions, genetic diversity, and morphological variability among C. renggeri and C. rufipes justify questioning of the actual taxonomic status of these species. The answer of this puzzle is clear when observing the number of 18S rDNA clusters of these ants, as C. rufipes has only two clusters whereas C. renggeri has four.

    This work deals with occurrence, distribution as well as biology and vectorial capacity of the ornate dog tick (Dermacentor (D.) reticulatus). Until 30 years ago this tick has only been described in a few natural foci in southern Germany. Its distribution has however expanded in the course of the last years. With the exception of northern Germany it is now covering large areas of Germany. This is particularly the case in the Upper Rhine Valley, Saarland and the Mark Brandenburg. However, it is endemic in many other areas of Germany as well. The transformation of agricultural land into fallow land, an increase in host reservoirs and climatic changes are discussed as main contributors to this change. Little is known about the role of this species as a vector for virus, rickettsia, bacteria and protozoa as well as its medical and veterinary importance. D. reticulatus is a vector for Babesia canis canis. It is reported here about a case of autochthonous babesiosis in a dog from Berlin/Brandenburg.

    Objective: To find out the most resistant strain of Spodoptera litura (S. litura) from Tamil Nadu, Kerala and Karnataka by synthetic insecticide treatment. Methods:Using leaf disc no-choice method, the insects were tested with different doses for pesticides. The LC50 and LC90 values were calculated by probit analysis. Results:In the insect bioassay, the cypermethrin insecticide showed significantly higher LC50 values of 14.699 g/L and 15.738 g/L against the Tamil Nadu and Kerala S. litura insect cultures respectively. The body length of 2nd, 3rd and 4th instar larvae were significantly higher (P≤0.05) in TTP insect population [(19.2±2.3) mm, (28.05±3.20) mm, (36.1±2.0) mm], when compared with KTK [(18.5±2.7) mm, (23.38±2.00) mm, (31.75±2.70) mm] and control, KBB [(15.65±2.30) mm, (23.65±2.70) mm, (33.2±2.2) mm] populations. The body breadth of 3rd instar larvae was significantly higher (P≤0.05) in TTP insect population (4.9±1.1) mm, when compared with KTK (3.93±0.80) mm and control, KBB (3.65±0.70) mm populations. Conclusions: The present study clearly showed that field collected strains were highly resistant when compared to control. Based on our study, we conclude that reduced use of synthetic pesticides is necessary and IPM is a better way to reduce the development of pesticide resistance among strains of S. litura.

    Full Text Available Chrysomya megacephala (Diptera: Calliphoridae, popularly known as blowfly, has a great capacity for dispersion and, due to factors such as food abundance and favorable climate, it colonizes Brazil completely in a short time. These insects are important to the sectors of epidemiology, public health and forensics, especially due to carrying microorganisms such as bacteria, viruses, protozoa and helminthes, which are responsible for the spread of diseases such as dysentery, cholera, botulism, typhoid fever, brucellosis, polio, smallpox and tuberculosis. The objective of this study was to verify the diversity of bacteria carried by this species in the Federal University of Mato Grosso – Campus of Sinop during the month of January of 2012. The flies were collected using two traps baited with 100 g of fresh sardines on each and maintained in the field for 24 hours. Twenty specimens of C. megacephala were placed in Petri dishes, to walk for two minutes upon Nutrient Agar (NA. After establishment of the colonies, isolation of the bacteria on the NA medium and their multiplication in test tubes containing the same culture medium was performed, and later sent to identification by gas chromatography. The bacteria encountered were Aquaspirillum polymorphum; Burkholderia ambifaria; Burkholderia anthina; Burkholderia cepacia; Burkholderia cenocepacia; Burkholderia pyrrocinia; Burkholderia stabilis; Paenibacillus macerans; Virgibacillus pantothenticus, Bacillus subtilis e Photorhabdus luminescens luminescens, with the last two species considered of importance in the plant protection sector.

    Amblyomma cajennense F. is one of the best known and studied ticks in the New World because of its very wide distribution, its economical importance as pest of domestic ungulates, and its association with a variety of animal and human pathogens. Recent observations, however, have challenged the taxonomic status of this tick and indicated that intraspecific cryptic speciation might be occurring. In the present study, we investigate the evolutionary and demographic history of this tick and examine its genetic structure based on the analyses of three mitochondrial (12SrDNA, d-loop, and COII) and one nuclear (ITS2) genes. Because A. cajennense is characterized by a typical trans-Amazonian distribution, lineage divergence dating is also performed to establish whether genetic diversity can be linked to dated vicariant events which shaped the topology of the Neotropics. Total evidence analyses of the concatenated mtDNA and nuclear + mtDNA datasets resulted in well-resolved and fully congruent reconstructions of the relationships within A. cajennense. The phylogenetic analyses consistently found A. cajennense to be monophyletic and to be separated into six genetic units defined by mutually exclusive haplotype compositions and habitat associations. Also, genetic divergence values showed that these lineages are as distinct from each other as recognized separate species of the same genus. The six clades are deeply split and node dating indicates that they started diverging in the middle-late Miocene. Behavioral differences and the results of laboratory cross-breeding experiments had already indicated that A. cajennense might be a complex of distinct taxonomic units. The combined and congruent mitochondrial and nuclear genetic evidence from this study reveals that A. cajennense is an assembly of six distinct species which have evolved separately from each other since at least 13.2 million years ago (Mya) in the earliest and 3.3 Mya in the latest lineages. The temporal and spatial diversification modes of the six lineages overlap the phylogeographical history of other organisms with similar extant trans-Amazonian distributions and are consistent with the present prevailing hypothesis that Neotropical diversity often finds its origins in the Miocene, after the Andean uplift changed the topology and consequently the climate and ecology of the Neotropics.

    The giant honeybee Apis dorsata often forms dense colony aggregations which can include up to 200 often closely related nests in the same location, setting the stage for inbred matings. Yet, like in all other Apis species, A. dorsata queens mate in mid-air on lek like drone congregation areas (DCAs) where large numbers of males gather in flight. We here report how the drone composition of A. dorsata DCAs facilitates outbreeding, taking into the account both spatial (three DCAs) and temporal (subsequent sampling days) dynamics. We compared the drones' genotypes at ten microsatellite DNA markers with those of the queen genotypes of six drone-producing colonies located close to the DCAs (Tenom, Sabah, Malaysia). None of 430 sampled drones originated from any of these nearby colonies. Moreover, we estimated that 141 unidentified colonies were contributing to the three DCAs. Most of these colonies were participating multiple times in the different locations and/or during the consecutive days of sampling. The drones sampled in the DCAs could be attributed to six subpopulations. These were all admixed in all DCA samples, increasing the effective population size an order of magnitude and preventing matings between potentially related queens and drones.

    Body melanisation in insects is polygenic, resulting from genetic polymorphism or phenotypic plasticity, with diverse implications ranging from thermal budgeting to reproductive success. In this study, we assessed the, mate choice, reproductive success, and offspring colouration of typical (T) and melanic (M) morphs of the ladybird Menochilus sexmaculatus paired at three temperatures 15°C, 25°C and 35°C. Mating success of the two morphs and the consequences for offspring fitness and offspring phenotype under these temperature regimes were evaluated. Melanic adults of both sexes achieved significantly higher mating success at 15°C and 25°C, but at 35°C no influence of adult morph on mate selection was observed. Melanic females were more fecund than typical females at all temperatures. Offspring of melanic parents developed faster than those of typicals at 15°C and 25°C, but not at 35°C. Evidence was also found of phenotypic plasticity in colour form at 15°C and 35°C. At 25°C the parents of pure (T) and (M) morphs produced offspring of the same morph. However, low temperature induced partial melanisation among the offspring of typical parents (T). Whereas at 35°C the offspring of (T) parents became paler in colour with very fine zigzag lines on elytra, i.e. they decrease the degree of melanisation. Pure melanics (M) compensated for elevated temperature stress by producing offspring that were either pure melanic but small or large with reduced melanisation. Our results on offspring phenotype variation indicate that the degree of melanism in morphs is a result of environmentally regulated expression of the parental genotype.

    Full Text Available α-amylase is one of the enzymes that has crucial role in extra-oral digestion (EOD of hemipteran insects. An α-amylase was purified and biochemically characterized from the salivary glands of Andrallus spinidens showing its considerable role in EOD process. It was found an enzyme by specific activity of 4.22 U/mg protein, recovery of 14.67 % and purification fold of 13.83-fold as well as molecular weight of 26 kDa. By using two buffer solutions, optimal pH of the purified α-amylase was found to be 9 for both universal and Tris-HCl buffers. Our findings revealed that the purified α-amylase had the highest activity at the temperatures of 35 and 40 °C, and were stable for 96 h at these temperatures. Kinetic parameters of the purified enzyme show that both starch and glycogen, are the suitable substrates for the enzymatic assay, but a lower Km demonstrated glycogen as a more appropriate substrate. Among the cations used to show their possible involvement in active site of the enzyme, Ca2+2+, Mg and one concentration of Cu2+ increased the α-amylase activity but Na+ decreased the enzyme activity. Triton X-100 increased the enzyme activity but SDS, EDTA, EGTA and TTHA decreased it, indicating involvement of metal ions in the active site of the purified α-amylase.

    2015-12-01

    Full Text Available Bats throughout the world are preyed upon primarily by vertebrates, but some are also attacked by invertebrates. We report two cases of bats entangled in webs of the giant-spider Nephilingis cruentata in southeastern Brazil. The first incidence occurred in December 2012, on which a female Eptesicus diminutus was found dead. The second occurred in March 2013, in which a male Tadarida brasiliensis was removed from the web alive, and later released. The animals showed no predation marks on the body, and both events were recorded after heavy rains. We suspect that the bats may have become entangled in the webs while seeking shelter from rain, or while foraging for insects. Even though the bats were not preyed upon, this spider cannot be ruled out as an opportunistic predator of small bats, as has been observed outside of Brazil.

    2006-07-01

    Orb-weaving spiders spin five fibrous silks from differentiated glands that contain unique sets of proteins. Despite diverse ecological functions, the mechanical properties of most of these silks are not well characterized. Here, we quantify the mechanical performance of this toolkit of silks for the silver garden spider Argiope argentata. Four silks exhibit viscoelastic behaviour typical of polymers, but differ statistically from each other by up to 250% in performance, giving each silk a distinctive suite of material properties. Major ampullate silk is 50% stronger than other fibers, but also less extensible. Aciniform silk is almost twice as tough as other silks because of high strength and extensibility. Capture spiral silk, coated with aqueous glue, is an order of magnitude stretchier than other silks. Dynamic mechanical properties are qualitatively similar, but quantitatively vary by up to 300% among silks. Storage moduli are initially nearly constant and increase after fiber yield, whereas loss tangents reach maxima of 0.1-0.2 at the yield. The remarkable mechanical diversity of Argiope argentata silks probably results in part from the different molecular structures of fibers and can be related to the specific ecological role of each silk. Our study indicates substantial potential to customize the mechanics of bioengineered silks.

    2013-04-01

    Full Text Available Spodoptera litura is a notorious leaf feeding insect pest of more than one hundred plants around the Asia-Pacific region. Host plant survey for two years from three different locations in cotton belt revealed 27 plant species as host plants of S. litura belonging to 25 genera of 14 families including cultivated crops, vegetables, weeds, fruits and ornamental plants. Major host plants on which it thrived for maximum period were Gossypium hirsutum L., Ricinus communis L., Brassica oleracea var. botrytis L., Colocasia esculenta L., Trianthema portulacastrum L. and Sesbania sesban L.. Eggs were also collected from tree plants but larvae did not complete their development. Reliance of S. litura on major plant species of cultivated crops necessitates their regular monitoring especially during March to April for their population abundance and early warning for their management on commercial crops like cotton.

    Full Text Available In recent years, the diseases of shrimps hindered the development of shrimp culture. Hence, the use of probiotic bacteria in aquaculture has tremendous scope and the study of the application of probiotics in aquaculture has a glorious future. In the present study, the probiotics was applied (experimental for the larval rearing of P. monodon which is compared with control tanks (without probiotics. The temperature and alkalinity of both control and experimental tanks were more of less same. The pH of the control tank w as 8.4 and the experimental tank was 8.2.The dissolved oxygen was higher in experimental tank (6.12ml/litre and lower in control tanks (5.75ml/litre. Likewise, the ammonia was higher in control tanks (0.19 mg/litre rather than experimental tanks (0.15mg/litre. The survival rate of different larval stages (nauplii, zoea and mysis were maximum in the present study than that of control tanks. The final survival rate of the post larvae from the control and experimental tank was 70 and 30% respectively. The average length of all post larvae was maximum when reared in experimental tank than control tanks. The general conclusion obtained from the present study is that the probiotics plays a vital role in maintaining water quality parameters throughout the larval cycle. It is clear from the microbial load data that vibrio sp. is dominant in the control tanks than in experimental tanks.

    Full Text Available Nests of Hylaeus aff. guaraniticus (Schrottky, 1906 were parasited by females of Gasteruption brachychaetum Schrottky, 1906 in trap nests in São Paulo (Brazil. This is thefirst host record of a Gasteruptiidae in the Neotropical Region. The behavior of a G.brachychaetum female entering a host's nest is described as follows: an inquiline female hovered near the host's nest, landed and detected that a female of H. aff. guaraniticus was inside the nest, waited for the host female to fly out, entered backwards into the nest, remained there for almost six minutes, and then went out the nest. The development time of immature stages of G.brachychaetum varied between 16 and 299 days.Ninhos de Hylaeus aff. guaraniticus (Schrottky, 1906foram parasitados por fêmeas de Gasteruption brachychaetum Schrottky, 1906 em ninhos-armadilha em São Paulo (Brasil.

    Full Text Available Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion. Some important aspects of this process were studied in a circular arena allowing the combined radial post-feeding dispersion from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the arena was divided in 72 identical sections starting from the center. The distance from the center, the depth and weight of each pupa were evaluated. Statistical tests were done to verify the relation between weight, depth and distance for pupation. From the total an average of 976 larvae released (488 for each species were collected considering both experiments 456 C. megacephala pupae and 488 of C. albiceps. This demonstrates that C. albiceps probably preyed on 32 C. megacephala larvae during post-feeding dispersion. The study of this dispersion process can be used to estimate the postmortem interval (PMI of human cadavers in legal medicine.As moscas- varejeiras utilizam-se de substratos discretos e efêmeros para alimentar suas larvas.

Alguns aspectos importantes desse processo foram estudados em uma arena permitindo a dispersão radial combinada de larvas de C. megacephala e C. albiceps. Para determinar a localização de cada pupa, a arena foi dividida em 72 setores iguais começando do centro. A distância a partir do centro, a profundidade e o peso de cada pupa foram determinados. Testes estatísticos foram feitos para verificar a relação entre peso, profundidade e distância para pupação. De um total em média de 976 larvas soltas (488 de cada espécie foram coletadas considerando ambos os experimentos 456 larvas de C. megacephala e 488 larvas de C. albiceps. Isso demonstrou que as larvas de C. albiceps provavelmente predaram 32 larvas de C. megacephala.

    Full Text Available Hypopharyngeal glands of honeybee are age-dependent structures that change with the size of acini and are correlated with various social behaviors. The histochemical structure of Apis cerana and A. mellifera worker hypopharyngeal glands in four different developmental stages wes stained with ninhydrin Schiff's and periodic acid Schiff's reagents (PAS for localization of proteins and carbohydrates, respectively, and examined with light microscopy. Nurse bees of both honeybee species had significantly larger glands as compared to guards and forgers, but there were no statistically significant differences between these two species after accounting for caste. Gland protein concentration increased progressively in nurse bees, and this was correlated with the appearance of enriched protein granules in the cytoplasm. In addition, the hypopharyngeal gland protein concentration of A. mellifera was higher than that of A. cerana even though gland size was not significantly different between species. However, gland size was shown to have decreased progressively in foragers and guards.

    Penaeus monodon juveniles were reared on semipurified diets containing various carbohydrates (maltose, sucrose, dextrin, molasses, cassava starch, corn starch or sago palm starch). Significant differences were observed between the type as well as the level of carbohydrate in the diet on the survival of the juveniles. Results indicate that there does not seem to be any correlation between survival and the complexity of the carbohydrates.

    After going unreported in the northwestern Atlantic Ocean for 18 years (1988 to 2006), the Asian tiger shrimp, Penaeus monodon, has recently reappeared in the South Atlantic Bight and, for the first time ever, in the Gulf of Mexico. Potential vectors and sources of this recent invader include: 1) discharged ballast water from its native range in Asia or other areas where it has become established; 2) transport of larvae from established non-native populations in the Caribbean or South America via ocean currents; or 3) escape and subsequent migration from active aquaculture facilities in the western Atlantic. This paper documents recent collections of P. monodon from the South Atlantic Bight and the Gulf of Mexico, reporting demographic and preliminary phylogenetic information for specimens collected between North Carolina and Texas from 2006 through 2012. The increased number of reports in 2011 and 2012, ranging from 102 mm to 298 mm total length, indicates that an adult population is present in densities sufficient for breeding, which is indicative of incipient establishment. Based on these reports of P. monodon, its successful invasion elsewhere, and its life history, we believe that this species will become common in the South Atlantic Bight and Gulf of Mexico in less than 10 years. Penaeus monodon is an aggressive predator in its native range and, if established, may prey on native shrimps, crabs, and bivalves. The impacts of an established P. monodon population are potentially widespread (e.g., alterations in local commercial fisheries, direct and indirect pressures on native shrimp, crab and bivalve populations, and subsequent impacts on the populations of other predators of those organisms) and should be considered by resource managers. The impacts of P. monodon on native fauna and the source(s) or vector(s) of the invasion, however, remain unknown at this time.

    Extraintestinal pathogenic Escherichia coli (ExPEC) has major negative impacts on human and animal health. Recent research suggests food-borne links between human and animal ExPEC diseases with particular concern for poultry contaminated with avian pathogenic E. coli (APEC), the avian ExPEC. APEC is also a very important animal pathogen, causing colibacillosis, one of the world's most widespread bacterial diseases of poultry. Previous studies showed marked atrophy and lymphocytes depletion in the bursa during APEC infection. Thus, a more comprehensive understanding of the avian bursa response to APEC infection will facilitate genetic selection for disease resistance. Four-week-old commercial male broiler chickens were infected with APEC O1 or given saline as a control. Bursas were collected at 1 and 5 days post-infection (dpi). Based on lesion scores of liver, pericardium and air sacs, infected birds were classified as having mild or severe pathology, representing resistant and susceptible phenotypes, respectively. Twenty-two individual bursa RNA libraries were sequenced, each yielding an average of 27 million single-end, 100-bp reads. There were 2469 novel genes in the total of 16,603 detected. Large numbers of significantly differentially expressed (DE) genes were detected when comparing susceptible and resistant birds at 5 dpi, susceptible and non-infected birds at 5 dpi, and susceptible birds at 5 dpi and 1 dpi. The DE genes were associated with signal transduction, the immune response, cell growth and cell death pathways. These data provide considerable insight into potential mechanisms of resistance to ExPEC infection, thus paving the way to develop strategies for ExPEC prevention and treatment, as well as enhancing innate resistance by genetic selection in animals.

    Leafcutting ants of the genus Atta are the most conspicuous members of the tribe Attini, the fungus-growing ants. Atta species have long attracted the attention of naturalists, and have since become a common model system for the study of complex insect societies as well as for the study of coevolutionary dynamics due to their numerous interactions with fungi and other microbes. Nevertheless, systematics and taxonomy of the 15 species in the genus Atta have proven challenging, due in part to the extreme levels of worker polymorphism these species display, leading to disagreements about the validity of as many as five different subgenera and calling into question the monophyly of the genus. Here, we use DNA sequence information from fragments of three mitochondrial genes (COI, tRNA leucine and COII) and one nuclear gene (EF1-alphaF1), totaling 1070 base pairs, to reconstruct the phylogenetic relationships of Atta species using maximum parsimony, maximum likelihood and Bayesian inference techniques. Our results provide support for monophyly of the genus Atta, and suggest that the genus is divided into four monophyletic groups, which correspond to four of the five previously erected Atta subgenera: Atta sensu stricto and Archeatta, each with species composition identical to earlier proposals; Neoatta and Epiatta, with major differences in species composition from earlier proposals. The current geographic ranges of these species suggest that the historical separation of South America from Central and North America has played a role in speciation within this genus.

    DNA identification of blow fly species can be a very useful tool in forensic entomology. One of the potential benefits that mitochondrial DNA (mtDNA) has offered in the field of forensic entomology is species determination. Conventional identification methods have limitations for sibling and closely related species of blow fly and stage and quality of the specimen used. This could be overcome by DNA-based identification methods using mitochondrial DNA which does not demand intact or undamaged specimens. Mitochondrial DNA is usually isolated from whole blow fly and legs. Alternate sources for mitochondrial DNA isolation namely, egg, larva, puparium and empty puparium were explored in this study. The sequence of DNA obtained for each sample for every life cycle stage was 100% identical for a particular species, indicating that the egg, 1st instar, 2nd instar, 3rd instar, pupa, empty puparium and adult from the same species and obtained from same generation will exhibit similar DNA sequences. The present study also highlighted the usefulness of collecting all life cycle stages of blow fly during crime scene investigation with proper preservation and subsequent molecular analysis. Molecular identification provides a strong basis for species identification and will prove an invaluable contribution to forensic entomology as an investigative tool in Malaysia.

    Full Text Available Abstract Trypoxylon is a genus of solitary crabronid wasps whose population genetics is poorly known. The purpose of the present study was to investigate the genetic variation and differentiation among five populations of Trypoxylon albitarse, a species widely distributed throughout the Neotropics, with records from Panama to northern Argentina. Eight species-specific microsatellite loci were used for genotyping 96 adult wasps (one female per nest sampled at five sites in Brazil. The analysis of allelic richness and private alleles indicated high genetic diversity in the populations sampled. Pairwise comparisons using the Fst and Dest indices revealed significant differentiation for all, but one pair of populations. Fst, Dest, AMOVA and assignment test values pointed to inter-population differentiation. Additionally, the analysis of population structure using Bayesian and PCA methods characterized two alternative genetic groups. The Mantel test indicated no correlation between genetic and geographic distances. Despite evidence of considerable dispersal capacity for T. albitarse, the data indicate low to moderate population structuring in this species.

    The ghost crab, Ocypode quadrata, is found on sandy beaches from the United States to Southern Brazil. Because there is still little information about the metabolism and reproduction of O. quadrata on the southern coast of Brazil, the objectives of this study were to (i) evaluate the effect of seasonal variations on the carbohydrate, lipid, and protein metabolism of O. quadrata at Rondinha Beach, a beach with high anthropogenic activity, and to compare it with data from Siriú Beach, which has less human activity; and (ii) describe the effect of seasonal variations on the histological characteristics of male and female gonads, in order to assess the reproductive capacity of the crabs. The gonads of male crabs showed no significant variations in the gonadosomatic index (GSI) and glycogen levels; however, histological analysis of the testes revealed that they are mature in the summer. In females, the GSI and glycogen values are higher in summer, concomitantly with the presence of mature oocytes. These results suggest that the reproductive peak of O. quadrata occurs in summer. The seasonal analysis of the biochemical parameters, as well as comparison with Siriú Beach, demonstrated that the ghost crabs of Rondinha Beach have a different pattern of metabolism than those of Siriú. This difference may be a consequence of differences in the environmental conditions as well as in the anthropogenic pressures, such as vehicle traffic and the increase in human population at the beach in summer.

    Objective: To evaluate the ovicidal activity of different botanical oil formulations againstHelicoverpa armigera and Spodoptera litura. Methods: Different botanical oils were formulated with different ratio to evaluate the ovicidal activity against H. armigera and S. litura at 5, 10, 15 and 20μl/L concentrations. Results: All the oil formulations showed the ovicidal activity against H. armigera and S. litura. The maximum ovicidal actvity of 76.74 and 69.36% was noticed at 20μl/L concentration in formulation 3 PONNEEM. Formulation 4 Pongam oil showed lower ovicidal activity of 31.34 and 24.76% against H. armigera and S. litura respectively. Among the formulations, PONNEEM exhibited statistically superior ovicidal activity against both insect pests. Conclusions: the present study clearly showed PONNEEM as a pontenial biopesticide to control the egg stage of economically important pests of H. armigera and S. litura. This is the first report for the ovicidal activity of PONNEEM against these two insect pests.

    The aphid species Sitobion avenae and Rhopalosiphum padi are the most important pests in wheat growing regions of many countries. In this study, we investigated the sublethal effects of imidacloprid on fecundity, longevity, and enzyme activity in both aphid species by comparing 3-h exposure for one or three generations. Our results indicated that 3-h exposure to sublethal doses of imidacloprid for one generation had no discernible effect on the survival, fecundity, longevity, or enzyme activity levels of aphids. However, when pulse exposures to imidacloprid were sustained over three generations, both fecundity and longevity were significantly decreased in both S. avenae and R. padi. Interestingly, the fecundity of R. padi had almost recovered by the F5 generation, but its longevity was still deleteriously affected. These results indicated that R. padi laid eggs in shorter time lags and has a more fast resilience. The change in reproduction behavior may be a phenomenon of R. padi to compensate its early death. If this is stable for the next generation, it means that the next generation is more competitive than unexposed populations, which could be the reason underlying population outbreaks that occur after longer-term exposure to an insecticide. This laboratory-based study highlights the sublethal effects of imidacloprid on the longevity and fecundity of descendants and provides an empirical basis from which to consider management decisions for chemical control in the field.

    Full Text Available Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or to additional food source, process referred as postfeeding larval dispersal. Some of the most important aspects of this process were investigated in Chrysomya megacephala, utilizing a circular arena to permit the radial dispersion of larvae from the center. To determinate the localization of each pupa, the arena was split in 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the larvae that disperse farther are those with higher weights. The majority of individuals reached the depth of burying for pupation between 7 and 18 cm. The study of this process of dispersion can be utilized in the estimation of postmortem interval (PMI for human corpses in medico-criminal investigations.

    The bedbugs Cimex lectularius and Cimex hemipterus are obligate hematophages in all their nymphal instars as well as in the adult stage. The efficiency with which the insects obtain blood from their hosts is directly related to their population dynamics. In the present study we compared the feeding process and salivary content in individuals of these two species when fed on different blood sources or host sites, using a cibarial pump electromyogram. Females ingested more blood than males but needed longer contact time with the host to complete the meal. The bedbug C. lectularius was more efficient than C. hemipterus in obtaining blood from mice and pigeons. With regard to the feeding site on mice, it was easier for the insects to obtain blood from the skin of the belly than that of the back. Individuals of C. hemipterus were able to maintain the cibarial pump functioning at higher frequencies for longer periods when fed on pigeons treated with anticoagulant. Although saliva from C. lectularius contained more hemeproteins and showed more anti-clotting activity its total protein content was similar to that of C. hemipterus. Overall, C. lectularius obtains a bloodmeal more efficiently from its hosts, which may have enabled this species to reach higher levels of infestation than C. hemipterus.

    1998-05-01

    Full Text Available The parasitic specificity of larval, nymph and adult Amblyomma cajennense on six different host species: Oryctolagus cuniculus, Rattus norvegicus, Gallus gallus domesticus, Anas platyrhynchus, Coturnix coturnix and Streptopelia decorata is described. In terms of the numbers of larvae and nymphs recovered, O. cuniculus was the best host species. The modal day for drop-off of larvae and nymphs was day three for the mammal hosts, but variable in the birds. We conclude that adult A. cajennense have a strong degree of specificity due to the fact that the tick failed to complete its life cycle on any of the evaluated hosts. The immature stages, on the other hand, showed a low level of specificity, most especially in the larval stage, indicating the existence of secondary hosts which probably serve as dispersers in the wild. The results also indicated a variable drop-off rhythm for larvae and nymphs in two periods, diurnal (6-18 hr and nocturnal (18-6 hr, which differed depending upon the host.

    Lymphoid cell culture from penaeid shrimps has gained much acceptance as an in vitro platform to facilitate research on the development of prophylaxis, and therapeutic strategies against viruses and for cell line development. However, lymphoid cells can be used as platform for in vitro research, only if they are in metabolically and mitotically active state in vitro with unaltered cell surface receptors. Through this study, we addressed the response of lymphoid cells to a new microenvironment at cellular and molecular levels; including the study of mitotic events, DNA synthesis, expression profile of cell cycle genes, cytoskeleton organization, metabolic activity and viral susceptibility. The S-phase entry and synthesis of new DNA was recorded by immunoflourescent technique. Cdc2, CycA, CycB, EF-1α and BUB3 genes involved in cell cycle were studied in both the cells and tissue, of which EF-1α showed an elevated expression in cells in vitro (∼ 19.7%). Cytoskeleton network of the cell was examined by studying the organization of actin filaments. As the markers for metabolic status, mitochondrial dehydrogenase, protein synthesis and glucose assimilation by the cells were also assessed. Viral susceptibility of the cell was determined using WSSV to confirm the preservation of cellular receptors. This study envisages to strengthen the shrimp cell line research and to bring forth lymphoid cell culture system as a 'model' in vitro system for shrimp and crustaceans altogether.

    Full Text Available We studied the reproductive characteristics of femaleAmblyoma variegatum in the laboratory. These included variations in engorgedweight, percentage body mass due to eggs, and quantity of eggs an engorgedfemale could lay. The results showed that different volumes of blood mealswould be consumed by the same progeny of Am. variegatum female ticks leading todifferent engorged weights. The study revealed that in Am. variegatum egg masscould account for as high as 51% of the engorged body weight. The female tickcould also oviposit as high as 31,487 eggs and also as low as 2421 eggs in samestudy cohorts. The study also showed that the actual engorged weight might notreflect the actual ovipositing capacity of the tick. Only the weight of the eggmass laid determined the actual quantity of eggs.

    Ntiba, M. J.; Harding, D.

    The type and quantity of food, the feeding intensity as well as the diel feeding pattern of the long rough dab Hippoglossoides platessoides are described. The interaction of the species with the biological environment is also assessed. The North Sea long rough dab feeds throughout the year with a definite maximum from April till August when over 85% of the fish sampled were feeding. It feeds principally on crustaceans (natant decapods), polychaetes, and echinoderms (ophiuroids), but also consumes O-group whitting ( Merlangius merlangus), long rough dab, and gobies (Gobiidae) in the east-central North Sea nursery grounds during the summer months. The species does not complete strongly for food with the other three most abundant pleuronectids, viz. plaice ( Pleuronectes platessa), common dab ( Limanda limanda) and lemon sole ( Microstomus kitt), as shown by a comparison of major prey items in their stomachs and the anatomical structure of their digestive tracts. The differences in the diet between the North Sea population(s) of long rough dab and the population(s) of the species from other North Atlantic areas are probably a manifestation of ecological differences amongst these ecosystems, especially in the availability and the distribution of prey organisms.

    Full Text Available Mahakam Delta area, which is situated in Kutai Kartanegara Regency, has become a pond center that gives a significant contribution to shrimp export of East Kalimantan Province. Pond-produced shrimps, however, do not always accord to the intention of cold storage companies at expected price. The companies even sometimes reject the request due to poor quality of the product. The decreasing shrimp quality may be due to maintenance process by the pond farmers as well as the improper collectors. In the other hand, importing countries have decided more and more restricted requirements for the imported fishing products. This study was held in Muara Jawa, Anggana, and Muara Badak Districts using techniques of data collection of in-depth interview with twelve respondents. In order to improve shrimp quality, farmers or the producers have to formulate a strategy towards the improvement of the post harvest shrimps from the pond using an Analytical Hierarchy Process (AHP. Results of the AHP consist of as follows: (1 application of pond shrimp post harvest technology and improvement of facilities and accommodation that support the quality improvement of the pond shrimps, (2 human resource quality improvement of pond farmers, collectors, and field instructors, (3 development of pond culture by applying best practices principle and local policies in order to improve the quality of the pond shrimps, and (4 improvement of interagency coordination, monitoring, and evaluation to enhance the pond shrimp quality

    Full Text Available Chemical analysis of turmeric (Curcuma longa extracts using TLC/densitometry, showed an extract contain 21.57%w/w of three important curcuminoids: curcumin, desmethoxycurcumin and bisdesmethoxycurcumin. GC and MS were used to analyze volatile oils. Aromatic turmerone, α-turmerone and zingiberene were also obtained. Qualitative and quantitative analyses alcoholic extract of Andrographis paniculata using TLC, revealed that the extracts contain three important compounds in total lactone of 30.49% w/w. There are andrographolide,14-deoxy-11-12-didehydroandrographolide and neoandrographolide. TLC-chromatogram of Clinacanthus nutans extract after reacted with anisaldehyde/sulfuric acid showed a 9 key compounds, while preliminary neutralization test of the compounds revealed that there were active compounds against HSV-1 virus. In vitro efficacy test revealed that Curcuma longa and Andrographis paniculata extracts at 250 and 1,500 mg/L could eradicate 15 isolates of Vibrio spp. which were isolated from infected shrimps. Effects of medicinal plant extracts incorporated into the diet on shrimp immune responses were investigated. Shrimp fed diet containing Clinacanthus nutans extract at 20 mg/kg of diet had good growth, FCR and immune responses. The shrimp that were fed diet containing Curcuma longa extracts at 25 mg/kg of diet for 7-14 days showed high resistance to Vibrio harveyi. Likewise, the shrimp fed Andrographis paniculata extract at 25 mg/ kg of diet for 14 days had a higher resistance to WSSV. Incorporating the medicinal extracts at higher levels resulted in reduction in diet palatability which consequently had an effect on a decrease in growth, immune responses and resistance to bacterial and WSSV infection.

    This study investigated the potential effects of flunitrazepam (known as "date rape drug") on the developmental cycle of Chrysomya megacephala, an important forensic species, and their possible implications for the calculation of the PMI. A 1050 C. megacephala eggs were divided into five groups with seven replications each. The eggs were placed on artificial diet prepared with four drug concentrations of flunitrazepam (4, 8, 16, and 32 ng/g), besides the control group (prepared with water). Were evaluated the potential effects on development time, weight gain, and mortality during the cycles. The drug had no significant effect on development time or mortality although it did affect the weight of the pupae and adults (Kruskal-Wallis, p < 0.05). The result can be deduced that the determination of the postmortem interval is not affected.

    Stores products such a grains, flours, dry fruits and spices are normally infested by pests as beetles (Lasioderma serricorne), mites and moths, depreciating the product visually and promoting its deterioration. To improve the quality of spices, medicinal plants and others foodstuffs there is a need for adequate methods of handling, correct identification of the species, adequate collection and storage. The objective of this work was to determine the dose of gamma radiation for the disinfestation of medicinal and aromatic plants infested by L. serricorne. The plants used in this study were Chamomilla recutita L. and Pimpinela anisum L. in this dehydrated form. The experiment was carried out in the Laboratorio de Inseticidas e Acaricidas from Instituto Biologico/SP, during the months of January and May 2006, and the irradiations were carried out in the Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN/SP, using and experimental Cobalt 60 irradiator, model Gammacell 220. Each treatment consisted of 5 parcels containing 10 g of dehydrated products infested with 20 last instar larvae of L. serricorne, conditioned in plastic 10 x 10 cm containers with small punctures in the cover to allow internal aeration. The substratum previously infested was submitted to increasing doses of gamma radiation: 0: 0.5; 0.75; 1.0; 1.25; 1.50; 1.75; 2.0; 2.25; 2.50 and 2.75 kGy. After irradiation, the samples were kept in a acclimatized room at 27 {+-} 2 deg C of temperature and relative humidity of 70 {+-} 5% and after a 45 days period the number of adults insects emerged was evaluated. The disinfestation dose of gamma radiation for last instar larvae L. serricorne on Chamomilla recutita L. and Pimpinela anisum L. was 2.0 kGy. (author)

    Shrimp cell lines are yet to be reported and this restricts the prospects of investigating the associated viral pathogens, especially white spot syndrome virus (WSSV). In this context, development of primary cell cultures from lymphoid organs was standardized. Poly-l-lysine-coated culture vessels enhanced growth of lymphoid cells, while the application of vertebrate growth factors did not, except insulin-like growth factor-1 (IGF-1). Susceptibility of the lymphoid cells to WSSV was confirmed by immunofluoresence assay using monoclonal antibody against the 28 kDa envelope protein of WSSV. Expression of viral and immune-related genes in WSSV-infected lymphoid cultures could be demonstrated by RT-PCR. This emphasizes the utility of lymphoid primary cell culture as a platform for research in virus-cell interaction, virus morphogenesis, up and downregulation of shrimp immune-related genes, and also for the discovery of novel drugs to combat WSSV in shrimp culture.

Repellent activity of cinnamaldehyde was compared against its two structural analogs (methyl cinnamate and ethyl cinnamate), and repellent effect of cinnamaldehyde formulated in agaro-pectin was also determined. Results in Y-typed olfactometer showed that the Cinnamomun cassia bark powder and Syringa oblata bud powder had extremely significant repellent effect, and repellent activity of three tested compounds was expressed in a declining order of cinnamaldehyde, methyl cinnamate and ethyl cinnamate. Results in basin-shaped olfactometer showed that repellent index of cinnamaldehyde formulated in agaro-pectin almost reached 100%against Lasioderma serricorne during a four-day test period. Thus cinnamaldehyde as component of tobacco flavor could be used to make agaro-pectin repellent against Lasioderma serricorne in tobacco warehouse.

    Full Text Available Two feeding trial were conducted to determine the effects of various sources of carotenoid on growth performance, disease resistance, blood parameters, stress tolerance and pigmentation in juvenile black tiger shrimp (Penaeus monodon. Trial I was performed in small shrimp (1 g average body weight. The shrimp were fed with control diet without carotenoid (diet 1 while diets 2 to 6 contained 50 mg/kg astaxanthin (Lucanthin Pink®, 125 mg/kg β-carotene (Lucarotin®, 200 mg/kg β-carotene (Lucarotin®, 125 mg/kg Betatene® extracted from Dunaliella and 3% dried Spirulina respectively. There was an improvement in color in all groups of shrimp fed caroteniod supplemented diets, but no significant differences in weight gain or survival among the shrimps fed each test diet (p>0.05. Resistance to white spot syndrome virus (WSSV infection and stress tolerance (salinity stress, were not significantly different among treatments. Trial II was performed in juvenile shrimp (10 g average body weight fed test diets containing 100 ppm astaxanthin (Lucanthin pink®, 125 mg/kg β-carotene (Lucarotin®, 250 mg/kg β-carotene (Lucarotin®, 250 mg/kg Betatene® and 3% dried Spirulina compared with those fed control diet without carotenoid. At the end of 6 weeks feeding period, shrimp fed control diet as well as astaxanthin and dried Spirulina supplemented diets had higher levels of total hemocyte counts than those of all β-carotene supplemented diets feeding group. However, phenoloxidase activity and clearance of pathogenic vibrio from the hemolymphwere not significantly different among the treatments (p>0.05. Astaxanthin levels were highest in the shrimp fed all carotenoid-supplemented diets. In conclusion, a natural carotenoid i.e. dried Spirulina and carotenoid extracted from Dunaliella which have a lower production cost than analytical carotenoid showed beneficial effects on shrimp feed supplement.

  13. Application of General Circulation Models to Assess the Potential Impact of Climate Change on Potential Distribution and Relative Abundance of Melanoplus sanguinipes (Fabricius (Orthoptera: Acrididae in North America

    Directory of Open Access Journals (Sweden)

    O. Olfert

    2011-01-01

    Full Text Available Climate is the dominant factor determining the distribution and abundance of most insect species. In recent years, the issue of climatic changes caused by human activities and the effects on agriculture has raised concern. General circulation model scenarios were applied to a bioclimatic model of Melanoplus sanguinipes to assess the potential impact of global warming on its distribution and relative abundance. Native to North America and widely distributed, M. sanguinipes is one of the grasshopper species of the continent most responsible for economic damage to grain, oilseed, pulse, and forage crops. Compared to predicted range and distribution under current climate conditions, model results indicated that M. sanguinipes would have increased range and relative abundance under the three general circulation model scenarios in more northern regions of North America. Conversely, model output predicted that the range of this crop pest could contract in regions where climate conditions became limiting.

    The structure of the karyotypes of two Otiorhynchus species belonging to separate subgenera, viz. Otiorhynchus s.str. bisulcatus and O. (Zadrehus) atroapterus, is compared and described for the first time. Both species have the same chromosome number (2n = 22), sex chromosome system of an achiasmate parachute type (Xy(p)), symmetric karyotype with the prevalence of metacentrics, similar meiotic behaviour, localization of NORs and positive DAPI signals. The main differences involve the morphology of autosomes and the X chromosome in the C-banding pattern and DAPI/CMA3 signals as well as in the presence of additional B chromosomes.

  15. Dynamics of cell and tissue genesis in the male reproductive system of ticks (Acari: Ixodidae) Amblyomma cajennense [corrected] (Fabricius, 1787) and Amblyomma aureolatum (Pallas, 1772): a comparative analysis.

    Ticks are classified into three families: Argasidae, Ixodidae, and Nutalliellidae. The taxonomy and phylogeny within Ixodidae are still discussed by the specialists, thus requiring further studies. Amblyomma cajennese and Amblyomma aureolatum (Brazil) belong to two species complexes known as "cajennese" and "ovale", respectively, and are directly related to the transmission of the Brazilian spotted fever. This confirms the medical and veterinary significance of these species, as well as the need for further morphological studies that will bring a better understanding of their taxonomy, phylogeny, and control. In this context, the present study aimed to characterize the morphology of the male reproductive system of A. cajennese and A. aureolatum when unfed and after 4 days of feeding, thereby seeking to: (a) distinguish the two species or "complexes", and (b) study an internal system which has the potential to be targeted by acaricides. Therefore, males from both species (unfed and after 4 days of feeding) were cold-anesthetized, dissected, and had their reproductive systems removed for histological analysis. The results showed that the morphology of the male reproductive system is generally similar between both species, like in other Ixodidae ticks, exhibiting a multilobed accessory gland complex related to seminal fluid secretion, a pair of vasa deferentia and a pair of testes housing germ cells (spermatocytes) in different stages. The main differences were found in the development of the accessory gland complex cells and germ cells, showing that the maturation of the male reproductive system starts later in A. aureolatum, when compared to A. cajennese. However, during the blood meal, A. aureolatum development is increased, thus making germ cell maturation and gland complex activity higher than in A. cajennese. This study shows the differences in the development of the male reproductive systems of both species, while providing information that can assist in the establishment of new control methods.

  17. RNAi-mediated knockdown of catalase causes cell cycle arrest in SL-1 cells and results in low survival rate of Spodoptera litura (Fabricius.

    Directory of Open Access Journals (Sweden)

    Haiming Zhao

    Full Text Available Deregulated reactive oxygen species (ROS production can lead to the disruption of structural and functional integrity of cells as a consequence of reactive interaction between ROS and various biological components. Catalase (CAT is a common enzyme existing in nearly all organisms exposed to oxygen, which decomposes harmful hydrogen peroxide, into water and oxygen. In this study, the full length sequence that encodes CAT-like protein from Spodoptera litura named siltCAT (GenBank accession number: JQ_663444 was cloned and characterized. Amino acid sequence alignment showed siltCAT shared relatively high conservation with other insect, especially the conserved residues which defined heme and NADPH orientation. Expression pattern analysis showed that siltCAT mRNA was mainly expressed in the fat body, midgut, cuticle and malpighian tube, and as well as over last instar larvae, pupa and adult stages. RNA interference was used to silence CAT gene in SL-1 cells and the fourth-instar stage of S. litura larvae respectively. Our results provided evidence that CAT knockdown induced ROS generation, cell cycle arrest and apoptosis in SL-1 cells. It also confirmed the decrease in survival rate because of increased ROS production in experimental groups injected with double-stranded RNA of CAT (dsCAT. This study implied that ROS scavenging by CAT is important for S. litura survival.

    Full Text Available The biology of immature stages of S.sphegea and different techniques for their laboratory rearing has been studied during the past five years (1972-77. This fly is one of the 18 Iranian species of snail-killing flies which is dominant in the focus area of schistosomiasis (Khuzestan Province in the south-west of Iran. The following procedures improved appreciably our laboratory rearin-technics and greatly reduced larval mortality: 1- Large number of fresh aquatic snails required for the progress of this study has been obtained at the entrances of the traditional under ground water canals (Ghanat in Teheran. These canals are almost permanent sources of snails because their water temperatures are rather constant through out the year and the water is by far protected from the surface pollution. In other cases, fresh snail was brought from distant swamp and rice fields. Attempts to maintain and to rear live aquatic snails, in large container equipped with aeration pump were not successful due to infection with coli form bacteria. Although the infected snails did not show any biological ill symptoms, could cause heavy mortality among larvae of flies. 2- Fly larvae were reared in plastic container of 28×32 cm. containing 7 to 8 liters of water (7 to 8 cm.depth. Eight to 12 laboratory vials filled with water were placed vertically in several rows in each container to secure uniform distribution of both snails and fly larvae. Fresh and dried leaves of lettuce were used to feed the snails. 3- Dead snails and their shells were picked out by forceps and half of the volume of water of all containers was drained from the bottom by siphoning every two days. 4- The surface pollution of water in the containers, which caused high mortality in different stages of larval development, was removed every four to five days by strips of blotting paper. The oily missed pollution on the water-surface was mostly due to dead snails, rotten leaves of lettuce and to a lesser extend caused by air pollution. 5- Several floating sticks on the inner periphery of each container provided resting place mostly for full-grown larvae. Many of the third stage larvae used to craw1 out of the containers, and sometimes suffering more than 50% mortality. The average survival of newly borne larvae up to pupal stage in 4 cohort of 15 was 71.7, whereas the average survival of 24 hours-fed larvae on crushed snail prior to release, in 5 cohort reached to 84% (min. 66. 66, max. 100%. It is concluded that the feeding of newly borne larvae on crushed aquatic snails for 24 hours prior to release is advantageous, in case of biological based on the mass release of larvae of the above snail-killing fly.

    Full Text Available Random amplified polymorphic DNA (RAPD markers were used to investigate the genetic relationship among nests of the carpenter ant, Camponotus rufipes, located in the same area. Five random oligodecamers were used to amplify DNA from 108 ant workers collected from six nests. A total of 47 RAPD markers were identified, which revealed low levels of genetic differentiation among nests (Fst = 0.00218 and a low average Shannon index (0.3727 among workers within nests. These results together suggest that the C. rufipes nest may be formed by a single, once-mated queen and that nests produced by queens that are genetically related tend to keep their nests in close proximity to one other.

    Stored products such as grains, flours, dry fruits and spices are normally infested by pests as beetles (Lasioderma serricorne), mites and moths, depreciating the product visually and promoting its deterioration. To improve the quality of spices, medicinal plants, seasoning and others foodstuffs there is a need for adequate methods of handling, correct identification of the species, adequate collection, pre and post-treatment procedures and adequate storage. The objective of this work was to determine the dose of gamma radiation for the disinfestations of medicinal and aromatic plants dehydrated infested by L. serricone. The plants used in this study were Cymbopogon citratus stapf (lemon grass) and Ocimun basillicum L. (basil) in this dehydrated form. The experiment was carried out in the Arthropods Laboratory of the Instituto Biologico/SP, during the months of January and May 2006, and the irradiations were carried out in the Instituto de Pesquisas Energeticas e Nucleares-IPEN/CNEN/SP, using an experimental Cobalt 60 irradiator, model Gammacell 220. Each treatment consisted of 5 parcels containing 10g of dehydrated products infested with 20 last instar larvae of L. serricorne, conditioned in plastic 10x10 cm containers with small punctures in the cover to allow internal aeration. The substratum previously infested was kept for 1 day in a acclimatized room at 27 {+-} 2 deg C, after this period the substratum was submitted to increasing doses of gamma radiation: 0; 0,5; 0,75; 1,0; 1,25; 1,50; 1,75; 2,0; 2,25; 2,50 e 2,75 kGy. After irradiation, the samples were kept in a acclimatized room at 27 {+-} 2 deg C of temperature and relative humidity of 70 {+-} 5 % and after a 45 days period the number of adults insects emerged was evaluated. The lethal dose of gamma radiation for L. serrricorne last instar larvae on Cymbopogon citratus stapf and Ocimun basillicum L. was 1,75 kGy. (author)

    The fumigant toxicity of Xylopia parviflora (A. Rich.) Benth (Annonaceae) root bark's essential oil (EO) against cowpea seed bruchid, Callosobruchus maculatus, was investigated in the laboratory. Dose had significant (P < 0.0001) effect on mortality at 6 hours after treatment (HAT) at a concentration of 6.25 μL/mL air which exerted 81.70% mortality, while there was no mortality in all other lower doses. At 12 HAT, 75.05% and 90.00% mortality were observed at doses of 3.15 and 6.25 μL/mL air, respectively. It was significantly (P < 0.05) higher than the mortality (50.58%) observed when 0.78 μL/mL air was applied. The lethal time for 50% of assayed adults (LT50) obtained when the bruchid was exposed to X. parviflora EO at a dose of 6.25 μL/mL air (2.71 h) was significantly lower than LT50 obtained at exposure of bruchid to other lower doses of 0.78-3.15 μL/mL air.

    Full Text Available Partial sequences of the mitochondrial COI gene of forty eight European and two Turkish population samples of Myzus cerasi from different winter hosts (Prunus spp. were subjected to phylogenetic analyses. The analysed M. cerasi samples emerged as paraphyletic relative to a Myzus borealis sample used as an out-group, and formed two major clades in neighbor joining, maximum parsimony, maximum likelihood and Bayesian inference trees, corresponding to subspecies living specifically on Prunus avium and P. cerasus. Multivariate discriminant analysis (method of canonical variates was applied to find out if morphological variation of samples correlated with mitochondrial COI and host plant information. Mean scores on the first two canonical variables clustered samples fully in accordance with their COI haplotypes and host plants confirming the existence of two morphologically similar winter host - specific subspecies of M.cerasi in Europe. No single morphological character enabled satisfactory discrimination between apterous viviparous females of the two subspecies. A three-character linear discriminant function enabled 92.37% correct identification of apterous viviparous females of M. cerasi cerasi (n=118 and 93.64% of M. cerasi pruniavium (n=110. A key for the morphological identification of the two subspecies is presented and their taxonomic status is discussed.

    2017-09-01

    Full Text Available The glucosinolate rich hot and cold hexane extracts of Brassica juncea had a negative effect on the development of Spodoptera litura larvae when they were fed on different concentrations of the extracts. Both larval growth index and pupal growth index declined with treatment. However the hot extract with 3-butenyl isothiocyanate as the predominant compound had a more deleterious effect as at 3125ppm the larvae were unable to complete their development. The nutritional indices too were more adversely affected with hot extract as compared to cold extract. The RGR, RCR, ECI and ECD declined significantly with increase in concentration of the hot hexane extract. The activity of antioxidant enzymes, SOD and catalase decreased while that of phosphatases, GSTs, phenol oxidases increased during the initial treatment duration but decreased on prolonged treatment of the larvae with LC50 concentration of hot extract. A similar trend was observed for glutathione and lipid peroxides but a decrease in ascorbate content was observed as compared to control. The findings reveal a toxic effect of 3-butenylisothiocyanate rich hot hexane extract of B. juncea on S. litura larvae.

    An 11-day trial was conducted to investigate the osmoregulatory capacity (OC) and regulation of K(+), Na(+), Ca(2+) and Mg(2+) of Penaeus monodon juveniles when exposed to K(+) deficient inland saline water (ISW) of four different salinities (5, 15, 25 and 35 ppt). The survival of juveniles showed a positive linear relationship (R(2) ranging from 0.72 to 0.98) with salinity. At the end of the trial, juveniles were able to survive only in 5 ppt of ISW and showed no changes in OC when transferred from ocean water (OW) to ISW. Further, the OC of juveniles in 5 ppt of ISW was significantly different (Pjuveniles exposed to 15, 25 and 35 ppt and exhibited strong serum K(+), Na(+), Ca(2+) and Mg(2+) regulation monitored over 16 h. In contrast, at 35 ppt, significant decrease (Pjuveniles, which in turn causes decrease in the OC of the juveniles. The results of this study suggest that K(+) deficiency in ISW has a negative effect on survival, OC and the ability of P. monodon juveniles to regulate serum Na(+), K(+), Ca(2+) and Mg(2+) concentrations. These effects are compounded as salinity increases.

    Full Text Available Elucidating the basic life-history of endangered species is the first important step in the conservation of such species. This study examined the reproductive ecology and the preimaginal morphology of the endangered ground beetle Elaphrus sugai Nakane (Coleoptera: Carabidae; currently, the Watarase wetland of the central Kanto Plain, Japan is the only confirmed locality of this beetle species. Laboratory rearing of reproductive adults collected in early April revealed that females can lay more than 131 eggs. Eggs were laid in mud, without an egg chamber. Larvae reached adulthood when fed a diet of mealworms, indicating that E. sugai larvae are insect larvae feeders. An earthworm diet, the optimal diet for larvae of a congeneric species (E. punctatus Motschulsky, was lethal to E. sugai larvae. The egg stage was 3-4 days in duration under a 16L8D cycle (22°C. The duration from hatching to adult eclosion was 23-42 days at various temperatures simulating those of the reproductive period. Larval morphology was similar to that of consubgeneric species described previously. The pupa is unusual, in that the setae on the abdominal tergites are long (twice as long as those of the abdominal segment and have somewhat "coiled" apices. Finally, the current endangered status of E. sugai was compared to that of E. viridis Horn, which has been regarded as the most endangered species of the genus worldwide.

Os resultados demonstraram que houve uma melhora no quadro hematológico dos animais após o programa de controle. Os tratamentos carrapaticidas, na forma em foram aplicados, não provocaram alterações desfavoráveis nos parâmetros clínicos e hematológicos dos eqüinos. Tais informações podem ser consideradas na busca de alternativas viáveis e seguras para o controle dessa espécie de carrapato.Clinical and hematological parameters were studied in equines submitted to a strategic control program of Amblyomma cajennense. The acaricide treatments were carried to each seven days and divided in two batteries, the first one began in April 2004 and the second in July 2004. A pyrethroid chemical base - 0.015% cypermethrin was used. Clinical examinations of the animals and complete hemograms were carried before and after the control program of the tick. Seric dosages of bilirrubins, gamma-glutamiltransferase (GGT, aspartate aminotransferase (AST, creatin kinase (CK, total protein, albumin, and globulins, were carried before and throughout the experiment. The results showed an improvement in the hematological parameters of the animals after the end of control program. The acaricide treatments did not cause undesirable alterations of the clinical and hematological parameters studied. Such information can be considered as viable and safe alternatives for the control of this tick.

    Full Text Available Blowflies use discrete, ephemeral breeding sites for larval nutrition. After exhaustion of the food supply, the larvae disperse in search of sites to pupate or to seek other sources of food in a process known as post-feeding larval dispersal. In this study, some of the most important aspects of this process were investigated in larvae of the blowflies Chrysomya megacephala exposed to a variety of light: dark (LD cycles (0:0 h, 12:12 h and 24:0 h and incubated in tubes covered with vermiculite. For each pupa, the body weight and depth of burrowing were determined. Statistical tests were used to examine the relationship of depth of burrowing and body weight to photoperiod at which burrowing occurred. The study of burial behavior in post-feeding larval dispersing can be useful for estimating the postmortem interval (PMI of human corpses in forensic medicine.Moscas-varejeiras usam substratos discretos e efêmeros para nutrição larval.

    The host-parasite associations between ground beetles (Coleoptera: Carabidae) and hairworms (Nematomorpha: Gordiida) collected from the Arctic (an understudied and ecologically important region) is described. Carabids and their parasites were collected from 12 sites spanning the 3 northernmost ecoclimatic zones of Canada (north boreal, subarctic, and high Arctic) using standardized methods. The beetles and hairworms were identified using traditional morphological approaches. Seven beetle species are recorded as hosts: Amara alpina, Pterostichus caribou, Pterostichus brevicornis, Pterostichus tareumiut, Pterostichus haematopus, Patrobus septentrionis, and Notiophilus borealis. All represent new host records (increasing the known North American host list from 14 to 21), and this is the first record of hairworm infection in the genus Notiophilus. Beetles from Banks Island, Northwest Territory, were infected in high numbers (11-19% per sampling period) and were used as an ecological case study. There was no significant relationship between infection status and host species, body size, or sex. Beetles collected in yellow pan traps and in wet habitats were more likely to be infected, likely due to water-seeking behavior induced by the parasites. Morphological examinations indicate that the hairworms collected from all locations represent a single, new species of Gordionus, making it only the sixth hairworm species and the third species of that genus found in Canada. Hosts are unknown for all other Canadian (and 1 Alaskan) Gordionus species.

    Full Text Available A glândula peçonhenta de Latrodectus mactans compõe-se: 1. De um saco formado por uma membrana de tecido conjuntivo peritonial, que se projeta proximalmente no ducto de peçonha. 2. De um manto externo, formado por 40-45 feixes musculares, circundando 3/4 da glândula, helicoidalmente. Os feixes inserem-se nas extremidades apical e basal da membrana sarcoperitonial; sua contração impele a peçonha, através do ducto, para as garras. 3. Do epitélio glandular, composto: a de células da glândula principal, b de células da glândula auxiliar, c de célula da glândula situada à entrada do ducto. As células das glândulas principal e auxiliar, juntas, formam uma unidade glandular de natureza ragiócrina. A secreção das células da glândula auxiliar passa, através das membranas celulares, para o interior das células glandulares principais, deslocando-se, juntamente com a secreção destas, para o pólo apical, a que ambas confluem, formando uma substância viscosa, fortemente condensada em virtude da eliminação de certos líquidos. Após a formação de 8 a 10 destas porções de secreções, os dois tipos de células esgotam-se; não se dá a regeneração ou substituição por outras células. A quantidade de peçonha, uma vez produzida, é armazenada na cavidade da glândula, sendo suficiente para tôda a vida do animal. As células da glândula situada á entrada do ducto, ou glândula lipócrina, produzem uma substãncia lipóide. Esta substância dissolve uma porção de corpúsculos das secreções segregadas pelas células principais e auxiliares. O líquido resultante é inoculado no tecido da prêsa ou do inimigo, por contração do manto muscular. Ao mesmo tempo, novas porções da peçonha armazenada são transportadas no sentido proximal e dissolvidas no líquido lipóide, preparando-se, assim, nova peçonha para outra picada. As formas das células e os pormenores histológicos estão explicados nas figuras que acompanham êste texto. Os músculos da glândula, ao contrário do que afirmam outros autores, verificamos serem de natureza "tetãnica", apresentando uma estriação transversal, típica. Certas zonas, porém, ricas em sarcoplasma, possuem propriedades "tônicas", mantendo-se sempre em certo grau de contratura que provoca a tensão adequada na membrana sarcoperitonial, o que permite um efeito imediato da contração da parte tetânica, no momento da picada.

    Odorant-binding proteins (OBPs) are important parts of insect olfactory systems, and sensitive olfaction is vital for phytophagous insects in host foraging. Electrophysiological studies are helpful in understanding olfactory sensing in Sitobion avenae (Hemiptera: Aphididae), but the functions of odorant-binding proteins in this insect are poorly understood. In this study, we used fluorescence competition assays to measure the binding specificities of SaveOBPs. The results showed that both SaveOBP2 and SaveOBP3 were superior to SaveOBP7 in binding green leaf volatiles. It was unexpected that SaveOBP7 bound trans-β-farnesene strongly, which was known as alarm pheromone of this species. Host volatiles were recognized much more easily by SaveOBP2, and the observed binding activity of SaveOBP2 equaled for tested green leaf volatiles. Our results imply that SaveOBP7 might play a more important role in aphid alarm pheromone discrimination.

    Biodiversity monitoring is increasingly being bolstered with high resolution data derived from remote sensing such as LIDAR (Light Detection and Ranging). We derived a series of topographical variables, including slope, azimuth, ground curvature and flow accumulation from LIDAR images and compared these to captures of female carabids in pitfall traps in Eastern boreal mixedwood forests. We developed a series of species-specific logistic models predicting the proportion of females for eight dominant species, including Agonum retractum, Calathus ingratus, Platynus decentis, Pterostichus adstrictus, Pterostichus coracinus, Pterostichus pensylvanicus, Sphaeroderus nitidicollis and Synuchus impunctatus. We used these models to test three hypotheses related to how the modest topography in boreal forests could influence the availability of microhabitats and possibly potential sites for oviposition and larval development. In general, topographic features such as north facing slopes and high flow accumulation were important predictors of the proportion of females. Models derived from larger scale topography, such as hillsides or small watersheds on the order of ¼-1 ha were better predictors of the proportion of females than were models derived from finer scale topography such as hummocks and small depressions. We conclude that topography likely influences the distribution of carabids based on hydrological mechanisms rather than factors related to temperature. We further suggest based on the scale of responses that these hydrological mechanisms may be linked to the attenuation of past disturbances by wildfire and the propensity of unburned forest patches and fire skips.

    Rough rice grains are often stored for extended periods before they are used or consumed. However, during storage, the rough rice is vulnerable to insect infestation, resulting in significant economic loss. Previous studies have shown that volatiles cues, physical characteristics, and taste chemicals on the grains could be the important key behavior factors for storage insect pests to locate the hosts and select oviposition sites. It is also well known that the transgenic Bt rough rice line T1C-19, which expresses a cry1C(⁎) gene has a high resistance to Lepidoptera pests. However, there were no evidences to show the consequences of host preference for non-target insect pests after growing Bt transgenic rice. In this study, the potential key factors of Bt rough rice were investigated for their impacts on the behaviors of non-target pest lesser grain borer Rhyzopertha dominica, the main weevil pest of grain and its parasitic wasps Anisopteromalus calandrae, the natural enemy of the beetle. Both electronic nose and electronic tongue analyses showed that the parameters of Bt rough rice were analogous to those of the non-Bt rough rice. The volatile profiles of Bt and non-Bt rough rice examined by gas chromatographic mass spectrometry (GC-MS) were similar. For most volatile compounds, there were no significantly quantitative differences in compound quantities between Bt and non-Bt rough rice. The densities of sclereids and trichomes on the rough rice husk surface were statistically equal in Bt and non-Bt rough rice. The non-target pest, R. dominica, and its parasitoid wasp, A. calandrae, were attracted to both rough rice and could not distinguish the transgenic T1C-19 from the isogenic rough rice. These results demonstrated that Bt rough rice has no negative impacts on the host preference behaviors of non-target stored product pest R. dominica and its parasitoid A. calandrae.

    A virulent strain PS-1 with high infectivity was isolated from the natural death larvae of Phyllotreta striolata. The strain PS-1 was characterized as Serratia marcescens based on its morphological, cultural, biolog identification system and 16S rDNA sequences analysis. The larvae of P. striolata were fed with turnip cubes which had been dipped in suspension culture of different concentrations (3×104, 3×106 and 3×108 cfu/mL) of S. marcescens PS-1 for 24 h. The corrected mortality rates were 36.1%, 63.9% and 75.0% at 4 d post-treatment, respectively. The LC50 was 7.98×106, 4.27×106 and 8.02×105 cfu/mL at 2, 3 and 4 d. The corrected mortality rate of P. striolata larvae fed with cabbage leaves which had been dipped in suspension culture of S. marcescens PS-1 under the concentrations of 1×108 cfu/mL was 23.25%at 12 d post-treatment. When the eggs of P. striolata were dipped in suspension culture of different concentrations (1×105, 1×107and 1×109 cfu/mL) of S. marcescens PS-1, there was no significant difference in the hatching rate between the control and treatments. The results suggest that S. marcescens PS-1 which has a strong virulence against the larvae and adults of P. striolata might be a good candidate as a potential microbial agent for biological control.%从自然死亡黄曲条跳甲幼虫体中分离出1株对黄曲条跳甲幼虫和成虫有较高致病性菌株PS-1。通过病原菌的形态观察、Biolog系统鉴定以及16S rDNA序列测定分析,确定菌株PS-1隶属于肠杆菌科、沙雷氏菌属的粘质沙雷氏菌Serratia marcescens族群。用菌株PS-1浓度为3×104、3×106和3×108 cfu/mL的菌悬液浸泡鲜萝卜块饲喂黄曲条跳甲幼虫24 h,4 d后的校正死亡率分别为36.1%、63.9%和75.0%;2、3和4 d的LC50分别是7.98×106、4.27×106和8.02×105 cfu/mL。用浓度1×108 cfu/mL的菌悬液处理菜心叶片饲喂黄曲条跳甲成虫,12 d的校正死亡率为23.25%。用浓度1×105、1×107和1×109 cfu/mL的菌悬液浸渍黄曲条跳甲卵,其孵化率与对照无显著差异。结果表明,粘质沙雷氏菌 PS-1菌株对黄曲条跳甲成虫和幼虫有较强的毒力,在黄曲条跳甲的生物防治方面具有一定的应用前景。

    The effects of powders from dry flower buds of Eugenia aromatica Baill., seeds of Piper guineense Schum and Thonn and fruits of Capsicum frutescens L. on adult behaviour, mortality and reproductive fitness of the cowpea seed beetle, Callosobruchus maculatus (Fab.) were investigated under ambient laboratory conditions. All experiments were carried out in glass Petri plates. All powders elicited aversion in adult beetles. The contact toxicity symptoms included restlessness, loss of coordination, knock down and eventual death of adult beetles. These behaviours were more pronounced with E. aromatica in which adult beetles died within 16 hours. P. guineense and C. frutescens powders did not cause 100% mortality of adult beetles, even after 24 hours. Each of the three powders significantly (P<0.05) reduced the mating competition of adult males after sub-lethal exposure for one, two, and three hours, respectively. E. aromatica powder caused more reduction in male mating competition for females than any of the other two powders after each period of exposure. Receptiveness of treated females to courting males was also decreased by exposure to any of the three powders. Similarly, E. aromatica powder caused greater decreases in female receptiveness to males than any of the other two powders after each period of exposure. Exposure of either adult male or female C. maculatus to the powders for sub-lethal times of three, six and nine hours significantly reduced the fecundity of the beetles. E. aromatica powder caused the most reduction of eggs laid and also significantly reduced fertility of the eggs.

    Exotic herbivorous insects have drastically and irreversibly altered forest structure and composition of North American forests. For example, emerald ash borer (Agrilus planipennis Fairmaire) from Asia has caused wide-scale mortality of ash trees (Fraxinus spp.) in eastern United States and Canada. We studied the effects of forest changes resulting from emerald ash borer invasion on epigaeic or ground beetles (Coleoptera: Carabidae) along a gradient of ash dieback and gap sizes in southeastern Michigan. Ground beetles were sampled in hydric, mesic, and xeric habitats in which black (Fraxinus nigra Marshall), green (Fraxinus pennsylvanica Marshall), and white (Fraxinus americana L.) ash were the most common species, respectively. During 2006-2007, we trapped 2,545 adult ground beetles comprising 52 species. There was a negative correlation between percent ash tree mortality in 2006 and catches of all beetles. Catches of Agonum melanarium Dejean (in 2006) and Pterostichus mutus (Say) (in 2006-2007) were negatively correlated with tree mortality and gap size, respectively. However, catches of Pterostichus corvinus Dejean were positively correlated with gap size in 2006. As ash mortality and average gap size increased from 2006 to 2007, catches of all beetles as well as P. mutus and Pterostichus stygicus (Say) increased (1.3-3.9 times), while species diversity decreased, especially in mesic and xeric stands. Cluster analysis revealed that beetle assemblages in hydric and mesic stand diverged (25 and 40%, respectively) in their composition from 2006 to 2007, and that hydric stands had the most unique beetle assemblages. Overall, epigaeic beetle assemblages were altered in ash stands impacted by emerald ash borer; however, these impacts may dissipate as canopy gaps close.

    Non-specfic carboxylesterase and glutathione S-transferase activity was measured in the ground beetle, Pterosthicus oblongopunctatus (Coleoptera: Carabidae), from five sites along a gradient of heavy metal pollution. A previous study determined that beetles from the two most polluted sites (site codes OLK2 and OLK3) were more susceptible to additional stressors compared with beetles from the reference site (Stone et al., Environ. Pollut. 113, 239-244 2001), suggesting the possibility of physiological impairment. Metal body burdens in ground beetles from five sites along the gradient ranged from 79 to 201 microg/g Zn, 0.174 to 8.66 microg/g Pb and 1.14 to 10.8 microg/g Cd, whereas Cu seemed to be efficiently regulated regardless of metal levels in the soil. Beetle mid- and hindguts were homogenized and the soluble fraction containing glutathione S-transferase (GST) and carboxylesterase (CaE) was assayed using kinetic analyses. Significantly higher levels of GST were found only in female beetles from the most polluted sites (OLK2 and OLK3; P=0.049, P<0.001, respectively) compared with the reference site (OLK7). In addition, OLK3 females had significantly higher levels of CaE compared with the reference beetles (P=0.01). Male beetles did not differ in enzyme activity along the metal gradient. Overall, obvious trends in detoxification enzymes were not detected in ground beetles in association with metal body burdens.

    2010-01-01

    A 2-year field study was conducted in the southern High Plains region of Texas to evaluate the effect of tillage system and cotton planting date window on seasonal abundance and activity patterns of predacious ground beetles. The experiment was deployed in a split-plot randomized block design with tillage as the main-plot factor and planting date as the subplot factor. There were two levels for each factor. The two tillage systems were conservation tillage (30% or more of the soil surface is covered with crop residue) and conventional tillage. The two cotton planting date window treatments were early May (normal planting) and early June (late planting). Five prevailing predacious ground beetles, Cicindela sexguttata F., Calosoma scrutator Drees, Pasimachus spp., Pterostichus spp., and Megacephala Carolina L. (Coleoptera: Carabidae), were monitored using pitfall traps at 2-week intervals from June 2002 to October 2003. The highest total number of ground beetles (6/trap) was observed on 9 July 2003. Cicindela sexguttata was the dominant ground dwelling predacious beetle among the five species. A significant difference between the two tillage systems was observed in the abundances of Pterostichus spp. and C. sexguttata. In 2002. significantly more Pterostichus spp. were recorded from conventional plots (0.27/trap) than were recorded from conservation tillage plots (0.05/trap). Significantly more C. sexguttata were recorded in 2003 from conservation plots (3.77/trap) than were recorded from conventional tillage plots (1.04/trap). There was a significant interaction between year and tillage treatments. However, there was no significant difference in the abundances of M. Carolina and Pasimachus spp. between the two tillage practices in either of the two years. M. Carolina numbers were significantly higher in late-planted cotton compared with those observed in normal-planted cotton. However, planting date window had no significant influence on the activity patterns of the

    Full Text Available During a period of three years (2006–2008 the carabid fauna in wet and humid forest habitats of different stages of succession was studied at the Puszcza Knyszynska (north-east part of Poland. The aim of this study was to determine how the assemblages of the carabid fauna change in relation to the ongoing process of succession. Using pitfall traps, 24 plots were sampled. The plots were located in stands of different age, from two year old plantations to more than 100 year old forests. Additionally, the stands were ordered in three moisture classes (wet, humid and very humid and two classes of soil richness. As indicators for change in the carabid fauna in relation to age of the stands Mean Individual Biomass (MIB, species diversity and share of forest species were used. By applying multivariate statistics the relation of the different habitat characteristics to changes in the carabid fauna was examined. During the study 8903 individuals belonging to 57 species were collected. Pterostichus niger represented 28% of the total catches and therefore the most common species. Another common species, Pterostichus melanarius, contributed to 13% of the total catch. This species was caught at every plot, even in the old forests. In contrast to the results obtained by Szyszko (1990 for fresh and dry pine stands, in this study the relation of MIB with the age of forest was not significant. Although the number of species was rather constant, the number of individuals belonging to the group of forest species significantly increased with the ageing of the forest. The multivariate analysis showed a relationship with ageing of the stands and soil richness rather than with moisture and size of the forest. According to the present paper, clear cuttings in wet and humid habitats do not cause a strong degradation of the carabid fauna.

    2010-01-01

    Full Text Available The aim of this paper was to examine the effect of different duration sound stress on immune organs of broiler chickens of different age. Nine groups, with 10 chickens in each group were included in experiment. The histological structure of bursa of Fabricius, thymus, and spleen were analyzed. The results indicated that the bursa of Fabricius, in relation to the other examined organs, was the most sensitive to this kind of stress. Histological changes of spleen and thymus were also observed, but less prominent except in chickens after more than 30 days of exposure to stress. According to our results, degree of histological changes of immune organs under the influence of sound stress depends on the length of exposure and age of chickens.

    210 one-day-old Tianfu meat ducklings ware divided into three groups,and fed on diets as follows: (1) control (Cu 12.16 mg kg-1),(2) copper toxic Ⅰ (Cu 850 mg kg-1) and (3)copper toxic Ⅱ( Cu 1 050 mg kg-1) for studies on effects of copper toxicity on lymphoid organs in duckling with the methods of experimental pathology and flow cytometry (FCM).The weight and growth index of the thymus,spleen and bursa of Fabricius were markedly reduced (P< 0.05 or P< 0.01) in both copper toxic group Ⅰ and Cu toxic group Ⅱ when compared with control group.The G0/G1 phase of the cell cycle of the thymus,spleen and bursa of Fabricius was much higher,and S,G2+M phases lower in Cu toxic groups Ⅰ and Ⅱ than in the control group.There were lymphocyte degeneration and depletion of lymphoid organs,and the reticular cells of spleen and bursa of Fabricius proliferated and the reticular cells of thymus were also degenerate and necrotic in Cu toxic groups.The results demonstrated that Cu toxicity seriously impaired the progression of lymphocytes from the G0/G1 phase to S phase,inhibited the development of lymphoid organs and caused marked pathological injury in lymphoid organs.The results also showed that the effect of Cu toxicity on the primary lymphoid organs occurred stronger than on the secondary lymphoid organs.The effect of Cu toxicity was the greatest on the bursa of Fabricius,followed hy the thymus,and then the spleen.Potential mechanisms underlying aforementioned observation were also discussed.key words: Copper toxicity,Lesion,Cell cycle,Lymphoid organ,Duckling

    Full Text Available The aphid, Aphis odinae (Van der Goot (Hemiptera: Aphididae is a polyphagous, occasional insect pest of cashew.  A field survey was conducted from 2014 to 2015 in cashew plantations to record the incidence of aphid and its predators.  Periodical sampling revealed, the occurrence of six species of aphidophagous predators comprising three species of coccinellids, viz., Scymnus castaneus Sicard, Cheilomenes sexmaculata (Fabricius and Pseudaspidimerus flaviceps (Walker and three species of syrphids, viz., Paragus serratus (Fabricius, Dideopsis aegrota (Fabricius and Ischidon scutellaris (Fabricius were found predating on A. odinae.  All the immature stages of predators were found predating on first, second, third and fourth instars of the aphid.  Among the coccinellids, the dominant species were S. castaneus (4.26 grubs/nut followed by C. sexmaculata (0.42 grubs/leaf and P. flaviceps (0.14 grubs/nut.  Of the syrphids, P. serratus 2.39 larvae/nut was the major predator. The species D. aegrota (1.2 larvae/leaf and I. scutellaris (0.5 larvae/nut were recorded as minor predators.  Seasonal abundance of predators was synchronized with the aphid with a maximum occurrence during February 2015.  The aphid population gradually reduced from April onwards due to the voracious feeding activity of the predators.  The study concluded that the aphidophagous predators, viz., coccinellids and syrphids play a  major role in managing the aphid A. odinae in cashew and could be encouraged for augmentation and conservation of these predators in a cashew based ecosystem.

    Full Text Available The outbreaks of IBD (infectious bursal disease are frequently observed among correctly vaccinated broiler flocks in Algerian Nord-East region. The present study aimed to search for the immunosuppression state as possible consequence of IBD. Our investigation focused on nine broilers flocks whom one suffering from IBD. Total of 400 bursa cloacae (bursa Fabricius were collected from broiler chickens during the rearing period or at slaughtering. The parameters of the bursa cloacae are evaluated: body weight ratio, index bursal, morphometric characteristics and the histopathological observations. The results obtained show that the weight and diameter of bursa Fabricius are not proportional to the age and weight of chickens. The weight and size of the bursa Fabricius were found lower than the accepted standards. According to the evaluation system in effect, 58 % of examined chickens belong to the poor category and 29 % to the excellent category. Such results indicate bursa atrophy and confirm state of immunosuppression which was suspected because of poor performances recorded in some broiler flocks. In conclusion, the bursa characteristics (body weight ratio, morphometric and histopathological studies are practical and not expensive tools for any field investigation to evaluate the immune status of broilers

    2016-01-01

    The present study was conducted in five different phytogeographic zones of the Brazilian state of Maranhão, three of which (the Amazon Forest, Cerrado, and Palm Groves) are more heterogeneous, whereas the other two (Marshlands and Mangroves) are more homogeneous. In each zone, nine sites were visited for the collection of necrophagous flies using bait traps in 2010, 2011, and 2012. The calliphorid and sarcophagid communities observed at each site were compared in terms of species richness, composition, and abundance. The more heterogeneous zones had higher species richness, except in the case of the sarcophagids in the forest habitats. The calliphorids Chloroprocta idioidea (Robineau- Desvoidy, 1830), Mesembrinella bicolor (Fabricius, 1805), Hemilucilia semidiaphana (Rondani, 1850) and Lucilia eximia (Wiedemann, 1819) were more closely associated with the Cerrado, Palm Grove and Amazon Forest zones, and Chrysomya megacephala (Fabricius, 194) with the Mangrove. In the sarcophagids, Peckia (Euboettcheria) subducta (Lopes, 1935) and P. (Pattonella) palidipilosa (Curran & Walley, 1934) were associated with the Amazon Forest, and P. (Sarcodexia) lambens (Wiedemann, 1830) and Tricharaea (Sarcophagula) occidua (Fabricius, 1794) with the Palm Grove and Cerrado zones. In the calliphorids, the greatest dissimilarity was recorded between the Amazon Forest and the Mangrove and Lowland grassland zones. In the sarcophagids, by contrast, the greatest dissimilarities were recorded between the Amazon Forest and all the other four zones. In general, then, the phytogeographic zones with the highest environmental heterogeneity were characterized by the greatest species richness and abundance of necrophagous flies. PMID:27798664

    2003-01-01

    Full Text Available This paper describes the effects of a strong type of vaccine - Moulthrop G603 º and an intermediate-plus type of vaccine - 228E º in meat-type chickens challenged with a very virulent strain of infectious bursal disease virus (vvIBDV. Blood samples and bursa of Fabricius were taken weekly up to 42 days of age. It was concluded that bursa of Fabricius weight, bursa weight:body weight ratio, body weight and antibody titer evaluated before and after challenge with vvIBDV were not enough to consistently and conclusively differentiate or estimate the protection given by vaccination. Quantitative evaluation of injury intensity and the number of altered lymphoid follicles revealed that Moulthrop G603 caused moderate microscopic lesions in one out of seven birds vaccinated at 14 days of age, while 228E vaccine did not induce IBD-typical microscopic lesions in the bursa of Fabricius. Good protection against bursal microscopic lesions was obtained when a strong type of vaccine was used before challenging with vvIBDV. It was concluded that quantitative evaluation of microscopic lesions might be useful to measure the injury induced by vaccinal IBDV, as well as the level of protection and/or immunosuppression induced by IBDV challenge in vaccinated and non-vaccinated chickens.

    Full Text Available Increased interest in biomass harvesting for bioenergetic applications has raised questions regarding the potential ecological consequences on forest biodiversity. Here we evaluate the initial changes in the abundance, species richness and community composition of rove (Staphylinidae and ground beetles (Carabidae, immediately following 1 stem-only harvesting (SOH, in which logging debris (i.e., tree tops and branches are retained on site, and 2 whole-tree harvesting (WTH, in which stems, tops and branches are removed in mature balsam fir stands in Quebec, Canada. Beetles were collected throughout the summer of 2011, one year following harvesting, using pitfall traps. Overall catch rates were greater in uncut forest (Control than either stem-only or whole-tree harvested sites. Catch rates in WTH were greater than SOH sites. Uncut stands were characterized primarily by five species: Atheta capsularis, A. klagesi, A. strigosula, Tachinus fumipennis/frigidus complex (Staphylinidae and to a lesser extent to Pterostichus punctatissimus (Carabidae. Increased catch rates in WTH sites, where post-harvest biomass was less, were attributable to increased catches of rove beetles Pseudopsis subulata, Quedius labradorensis and to a lesser extent Gabrius brevipennis. We were able to characterize differences in beetle assemblages between harvested and non-harvested plots as well as differences between whole tree (WTH and stem only (SOH harvested sites where logging residues had been removed or left following harvest. However, the overall assemblage response was largely a recapitulation of the responses of several abundant species.

    The catalogue of the ground beetles (Coleoptera: Carabidae) of the Republic of Macedonia is the result of our permanent investigation during 15 years. It is based on the critical review of the data in 255 scientific publications and the revision of the collections deposited in the museums in Macedonia (Skopje and Struga), other European countries (Berlin, Budapest, Vienna, Sofia) and the first author's private collection. For all of the species and subspecies we have presented the known literature references, precise data for the studied material and overall distribution in the Republic of Macedonia. The study of the material resulted in new country records of 10 genera, 101 species and 25 subspecies. First detailed records are provided for another 47 species and subspecies, and additional material was studied of 482 species and subspecies. Type material of 18 species and subspecies was also examined. Thirteen species and one subspecies were rejected from the list of Macedonian ground beetles. Six more species are treated as questionable and were not included in the present list. As a result, the presence of 571 species and 234 subspecies (626 taxa in total) in Macedonia is confirmed. These taxa are arranged in 104 genera, 31 subtribes, 35 tribes and 13 subfamilies. The most numerous in term of the species are the genera Bembidion (60), Harpalus (48) and Amara (46), as well as Pterostichus (26), Ophonus (19), Carabus (16), Trechus (16), Brachinus (16) and Dyschirius (15).

    Ground beetles are well known as beneficial organisms in agroecosystems, contributing to the predation of a wide range of animal pests and weed seeds. Tillage has generally been shown to have a negative effect on ground beetles, but it is not known whether this is because of direct mortality or the result of indirect losses resulting from dispersal caused by habitat deterioration. In 2005, field experiments measured direct, tillage-induced mortality, of four carabid weed seed predators, Harpalus rufipes DeGeer, Agonum muelleri Herbst, Anisodactylus merula Germar, and Amara cupreolata Putzeys, and one arthropod predator, Pterostichus melanarius Illiger, common to agroecosystems in the northeastern United States. Three tillage treatments (moldboard plow, chisel plow, and rotary tillage) were compared with undisturbed controls at two sites (Stillwater and Presque Isle) and at two dates (July and August) in Maine. Carabid activity density after disturbance was measured using fenced pitfall traps installed immediately after tillage to remove any effects of dispersal. Rotary tillage and moldboard plowing reduced weed seed predator activity density 52 and 54%, respectively. Carabid activity density after chisel plowing was similar to the undisturbed control. This trend was true for each of the weed seed predator species studied. However, activity density of the arthropod predator P. melanarius was reduced by all tillage types, indicating a greater sensitivity to tillage than the four weed seed predator species. These results confirm the need to consider both direct and indirect effects of management in studies of invertebrate seed predators.

    Biological control of insects by predators may be indirectly influenced by management practices that change the invertebrate community in agroecosystems. In this study we examined effects that mulching and weeding have on predatory beetles (Carabidae and Staphylinidae) and their potential prey in a highbush blueberry field. We compared beetle communities in unweeded control plots to those that were weeded and/or received a single application of compost or pine needle mulch. Compost mulch and weeding significantly affected the carabid community while the staphylinid community responded to compost and pine needle mulches. Effects because of mulch tended to intensify in the year after mulch application for both families. Estimates of species richness and diversity for Carabidae and Staphylinidae were similar in all plot types, but rarefaction curves suggested higher Carabidae richness in unmulched plots despite fewer individuals captured. Carnivorous Carabidae, dominated by Pterostichus melanarius, were most frequently captured in compost plots both years, and omnivores were most frequently captured in unweeded compost. Density of millipedes, the most abundant potential prey, was generally greater in mulched plots, whereas seasonal abundance of small earthworms varied among mulch types. Our results have potential implications for biological control in mulched highbush blueberries depending on beetle consumption rates for key pests and how rates are affected by alternative prey.

    Ash fertilization of forests returns nutrients to forest ecosystems and has a positive effect on soil pH.but it also may elevate Cd concentrations of forest biota.Cadmium concentrations of some forest insects(Formica ants.carabids and Coleopteran larvac from decaying wood)were investigated in southern Finland where two plots were fertilized with wood ash,while two other plots represented anfertilized control plots.In ants,mean Cd concentration was 3.6±1.4 mg/kg.with nest workers having significantly higher concen-trations than workers trapped in pitfall traps.Concentrations at fertilized and unfertilized plots were similar.In carabid beetles,the average Cd concentration of Carabus glabratus was 0.44±0.36 mg/kg.with no significant difference between control plots and fertilized plots.In another carabid beetle,Pterostichus niger,mean Cd concentration was higher at fertilized plots compared to control plots.We conclude that the variation of Cd concentra-tions in the insects studied is more efficiently controlled by species-specific differences than fertilization history of the forest floor.

    The European Commission Recommendation 2006/576/EC indicates that the maximum tolerable level of ochratoxin A (OTA) in poultry feeds is 0.1 mg OTA/kg. Thirty-six 1-day-old male broiler chicks were divided into two groups, a control (basal diet) and an OTA (basal diet + 0.1 mg OTA/kg) group. The OTA concentration was quantified in serum, liver, kidney, breast and thigh samples. The thiobarbituric acid reactive substances (TBARS) content were evaluated in the liver, kidney, breast and thigh samples. The glutathione (GSH) content, and catalase (CAT) and superoxide dismutase (SOD) activity were measured in the liver and kidney samples. Histopathological traits were evaluated for the spleen, bursa of Fabricius and liver samples. Moreover, the chemical composition of the meat was analysed in breast and thigh samples. In the OTA diet-fed animals, a serum OTA concentration of 1.15 ± 0.35 ng/ml was found, and OTA was also detected in kidney and liver at 3.58 ± 0.85 ng OTA/g f.w. and 1.92 ± 0.21 ng OTA/g f.w., respectively. The TBARS content was higher in the kidney of the ochratoxin A group (1.53 ± 0.18 nmol/mg protein vs. 0.91 ± 0.25 nmol/mg protein). Feeding OTA at 0.1 mg OTA/kg also resulted in degenerative lesions in the spleen, bursa of Fabricius and liver. The maximum tolerable level of 0.1 mg OTA/kg, established for poultry feeds by the EU, represents a safe limit for the final consumer, because no OTA residues were found in breast and thigh meat. Even though no clinical signs were noticed in the birds fed the OTA-contaminated diet, moderate histological lesions were observed in the liver, spleen and bursa of Fabricius.

    This study investigated the effects of dietary resveratrol at 0, 200, 400, or 600 mg/kg of diet on the performance, immune organ growth index, serum parameters, and expression levels of heat shock protein (Hsp) 27, Hsp70, and Hsp90 mRNA in the bursa of Fabricius, thymus, and spleen of 42-d-old female black-boned chickens exposed to heat stress at 37 ± 2°C for 15 d. The results showed that heat stress reduced daily feed intake and BW gain; decreased serum glutathione (GSH), growth hormone, and insulin-like growth factor-1 levels; and inhibited GSH peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities compared with birds subjected to thermo-neutral circumstances. Chickens that were fed diets supplemented with resveratrol exhibited a linear increase in feed intake and BW gain (P chickens that were fed diets without resveratrol during heat stress. In contrast, serum malonaldehyde concentrations were decreased (P chickens fed a resveratrol-supplemented diet. Heat stress also reduced (P heat stress and coincided with an increase in supplemental resveratrol levels. The expression of Hsp27, Hsp70, and Hsp90 mRNA in the bursa of Fabricius and spleen were increased (P heat stress compared with no heat stress. Resveratrol attenuated the heat stress-induced overexpression of Hsp27, Hsp70, and Hsp90 mRNA in the bursa of Fabricius and spleen and increased the low expression of Hsp27 and Hsp90 mRNA in thymus upon heat stress. The results suggest that supplemental resveratrol improves growth performance and reduces oxidative stress in heat-stressed black-boned chickens by increasing serum growth hormone concentrations and modulating the expression of heat shock genes in organs of the immune system.

  16. Hyperpigmentation Results in Aberrant Immune Development in Silky Fowl (Gallus gallus domesticus Brisson.

    Directory of Open Access Journals (Sweden)

    Deping Han

    Full Text Available The Silky Fowl (SF is known for its special phenotypes and atypical distribution of melanocytes among internal organs. Although the genes associated with melanocyte migration have been investigated substantially, there is little information on the postnatal distribution of melanocytes in inner organs and the effect of hyperpigmentation on the development of SF. Here, we analyzed melanocyte distribution in 26 tissues or organs on postnatal day 1 and weeks 2, 3, 4, 6, 10, and 23. Except for the liver, pancreas, pituitary gland, and adrenal gland, melanocytes were distributed throughout the body, primarily around blood vessels. Interaction between melanocytes and the tissue cells was observed, and melanin was transported by filopodia delivery through engulfed and internalized membrane-encapsulated melanosomes. SFs less than 10 weeks old have lower indices of spleen, thymus, and bursa of Fabricius than White Leghorns (WLs. The expression levels of interferon-γ and interlukin-4 genes in the spleen, and serum antibody levels against H5N1 and infectious bursal disease virus were lower in SF than in WL. We also found immune organ developmental difference between Black-boned and non-Black- boned chickens from SFs and WLs hybrid F2 population. However, degeneration of the thymus and bursa of Fabricius occurred later in SF than in WL after sexual maturity. Analysis of apoptotic cells and apoptosis-associated Bax and Bcl-2 proteins indicated that apoptosis is involved in degeneration of the thymus and bursa of Fabricius. Therefore, these results suggest that hyperpigmentation in SF may have a close relationship with immune development in SF, which can provide an important animal model to investigate the roles of melanocyte.

    Cara Van Der Wal

    Full Text Available Abstract Squillidae is the largest family in the Stomatopoda, with 47 genera to date. Phylogenetic analyses have shown Squilla Fabricius, 1787 and Oratosquilla Manning, 1968 to be para- or polyphyletic. Two poorly documented species within these genera, Squilla parva Bigelow, 1891 (eastern Pacific and Oratosquilla kempi (Schmitt, 1931 (western Pacific are not closely related to the respective type species of the genera in which they are currently placed. We herein redescribe S. parva and O. kempi based on type and other material, and propose two new genera for their reception, increasing the number of squillid genera to 49.

There has been a great interest in photonic band gap (PBG) materials since the concept was first proposed by Yablonovich[1] and John[2] in 1987. However, Nature had already created these PBG structures in living organisms long since, as was found recently in the Indonesian male Papilio palinurus butterfly[3], sea mouse Aphrodita[4], male Ancyluris meliboeus Fabricius butterflies[5], male peacock Pavo muticus feathers[6], and weevil Pachyrhynchus argus[7].

    The ability of the bursa of Fabricius to regenerate after gamma-irradiation and bone marrow reconstitution was examined in chickens thymectomized (TX) immediately after hatching. Irradiation (2 X 500 R) 3 weeks after hatching was followed by impaired bursa regeneration, as judged both by bursa/body weight ratios and by bursa follicle development 3-6 weeks later in TX as compared to control birds.

    Two new endemic butterfly species from the genus Bebearia: B. oshogbo sp. nov. and B. wojtusiaki sp. nov., are described from western Nigeria; B. oshogbo is most closely related to the Guineo-Congolian B. tentyris (Hewitson) and the Upper Guinean B. osyris (Schultze), whereas B. wojtusiaki constitutes a morphological and biogeographic link between the Central African B. plistonax (Hewitson) and the Upper Guinean endemic B. arcadius (Fabricius). The finding of these new species gives further strong evidence that western Nigeria should be recognized as a distinct biogeographic sub-region of West Africa, as the area hosts a substantial number of endemic taxa (listed in the discussion).

As there should be more higher-genus models to be discovered, this might be of interest. In the second part I shall discuss some quantum group aspects, especially issues of odd versus even N related to the Serre relations conjecture in our quantum loop subalgebra paper of 5 years ago and how we can make good use of coproducts, also borrowing ideas of Drinfeld, Jimbo, Deguchi, Fabricius, McCoy and Nishino.

    2014-02-01

    Full Text Available Weed seed predation is influenced for both biological and abiotic factors. Knowledge about these factors is necessary to optimize seed predation as a biological weed control measure. Here, we asked whether carnivorous carabid beetles can affect the seed predation. Additionally, the effect of weather on seed predation rate was investigated. For this purpose, 12, 1m² enclosures were installed in a field (block design with four treatments and three replications in northeastern Germany over a period of 23 days. Treatments in the enclosures were 1 without carabids, 2 with a natural density and species composition of carabids, 3 with granivorous carabid beetles (Pseudoophonus rufipes, Harpulus affinis, and 4 as 3 but additionally with carnivorous carabids (Pterostichus melanarius, Poecilus cupreus Seed predation rate was determined daily using seed cards with Poa annua and Stellaria media seeds. Temperature, relative air humidity and daily precipitation were measured as covariables. In the treatment with granivorous carabids seed predation rate was 54.3 (P. annua resp. 14.3 (S. media seeds per enclosure and day. In the treatment with granivorous and carnivorous carabids, seed predation rate was significantly lower for P. annua (46.6 seeds per enclosure and day, paired Wilcoxon-Test, p = 0.04 and equally high for S. media (14.4 seeds per enclosure and day. In enclosures containing non-manipulated carabid densities 9.1 seeds of P. annua and 7.2 seeds of S. media were lost per enclosure and per day, which is significantly higher than from enclosures that were void of carabids. The minimum night temperature was the only weather variable that significantly influenced seed predation rate. This work contributes to a better understanding of the factors influencing seed predation rates in the field.

    2015-01-01

    Abstract Butterflies and moths are found in all terrestrial environments and require efforts for a better understanding of its mega-diversity. These taxa have been the subject of several studies involving phylogeny, ecology and environmental impacts. Nevertheless, several areas in the tropics remain unexplored, resulting in gaps in the taxonomic composition and distribution of butterflies in endemic environments. Therefore, a survey of the butterfly fauna of the Bodoquena Plateau in Brazil was conducted. This area consists of tropical Atlantic Forests, with marginal influences of Savannah, Chaco and Pantanal. Sampling was carried out in 20 locations using Van Someren Rydon traps and insect nets between November 2009 and April 2015. Active collection of individuals was conducted from 9:00 to 17:00h, totaling 240 hours of sampling effort. In total, we registered 768 individuals belonging to 146 species of 98 genera, six families and 18 subfamilies. Nymphalidae was the richest family (84 species), followed by Hesperiidae (22 species), Riodinidae (14 species), Pieridae (12) Papilionidae (11 species) and Lycaenidae (five species). We sampled 239 nymphalids in traps, with 48 species, 30 genera, 15 tribes and five subfamilies. The most common species were Eunica macris (Godart, 1824), Dynamine artemisia (Fabricius, 1793) and Memphis moruus (Fabricius, 1775). Therefore, this study contributes to the knowledge of the Neotropical butterfly diversity and distribution, providing 37 new records and supporting the use of wildlife inventories as important tools for the knowledge of tropical forests biodiversity and conservation.

    Full Text Available This project was aimed to evaluate immunostimulatory effects of three therapeutic substances in broilers suffering from infectious bursal disease (IBD. For this purpose, 150 chicks were divided into five equal groups i.e. A, B, C, D and E having 30 birds each. Group A, B, C and D were challenged with infectious bursal disease virus. There were three immunostimulatory treatments i.e. levamisole (group A, vitamin E (group B, and bursinex (group C. Groups D and E were untreated control. Bursa body weight index, histopathology of bursa of Fabricius, plasma cell counting in Harderian gland and estimation of antibody response against infectious bursal disease virus was recorded. Vitamin E played a major role in improving the condition of birds suffering from infectious bursal disease, as it showed increased bursa body weight index (BBIx, less histopathological lesions in bursa of Fabricius, increased number of plasma cells in Harderian gland and high antibody response in infectious bursal disease infected broilers as compared to levamisole and bursinex. Levamisole played a minor role in improving condition of birds, while bursinex did not seem to be much effective against infectious bursal disease virus in this study.

    Forensic entomological specimens collected from human decedents during crime scene investigations in Malaysia in the past 6 years (2005-2010) are reviewed. A total of 80 cases were recorded and 93 specimens were collected. From these specimens, 10 species of cyclorrphagic flies were identified, consisting of Chrysomya rufifacies (Macquart) -38 specimens (40.86%), Chrysomya megacephala (Fabricius) -36 specimens (38.70%), Chrysomya villeneuvi (Patton) -2 specimens (2.15%), Chrysomya nigripes (Aubertin) -2 specimens (2.15%), Chrysomya pinguis (Walker) -1 specimen (1.08%), Hermetia illucens (Linnaeus) -1 specimen (1.08%), Hemipyrellia liguriens (Wiedemann) -5 specimens (5.37%), Synthesiomyia nudiseta (Wulp) -1 specimen (1.08%), Megaselia scalaris (Loew)-1 specimen (1.08%) and Sarcophaga ruficornis (Fabricius) -4 specimens (4.30%). In two specimens (2.15%), the maggots were not identifiable. Ch. megacephala and Ch. rufifacies were the commonest species found in human decedents from three different ecological habitats. S. nudiseta is an uncommon species found only on human cadavers from indoors. A total of 75 cases (93.75%) had a single fly infestation and 5 cases (6.25%) had double fly infestation. In conclusion, although large numbers of fly species were found on human decedents, the predominant species are still those of Chrysomya.

    The effect of dietary thyme-oil extract (TOE) supplementation on immune functions of broilers were assessed by feeding graded levels (50, 100, 200, or 400 ppm) of TOE to male broiler chicks during a 42-d feeding trial compared with negative- or positive-control diets. Dietary control treatments included a negative-control diet with no feed-additive supplementation and 2 positive-control groups supplemented with either virginiamycin or zinc bacitracin. In total, 300 1-day-old Ross × Ross male broilers were randomly assigned to 6 dietary treatments that consisted of 5 replicates of 10 birds each. On d 21 and 42, 2 birds from each replicate were killed by cervical cutting to measure the relative weights of spleen and bursa of Fabricius. At 25 d of age, chicks were injected with 0.5 mL of 10% SRBC suspension. Broilers fed with 200 ppm of TOE had heavier weights of bursa of Fabricius than those fed other dietary treatments at d 42 of age. Furthermore, dietary inclusion of 100 ppm of TOE resulted in higher (P < 0.05) total immunoglobulin response in primary antibody titer against sheep erythrocytes compared with other dietary treatments. On the other hand, diet modifications had no significant effect on blood leukocyte subpopulations and heterophil-to-lymphocyte ratio. These results suggest that dietary supplementation with TOE, especially at the level of 100 ppm, can improve immunological responses of broiler chicks.

    Full Text Available An outbreak of Marek’s disease was reported to occur in broiler chicken in Districts of Tasikmalaya and Ciamis. A total number of 58 tissues samples of broiler chicken were collected from 7 flocks of commercial broiler chicken farms in both Districts. The disease affected broiler chicken aged 17 to 24 days. Those chickens had been vaccinated to Newcastle Disease (ND and at age of 10 days had been vaccinated to Gumboro using blended bursa of fabricius. Tissue samples were fixed in 10% of buffered neutral formalin (BNF prior to haematoxilin and eosin (H and E stain using standard procedures. Histopathological features show that out of 58 samples, 32 (55.2% were infected by Marek’s Disease (19.0% were infected by Marek’s Disease, 20.1% were infected by Marek’s Disease and Gumboro, 16.1% Marek’s Disease and other infections, whereas 44.8% were infected by Gumboro alone or accompanied by other infections, ND and Colibasillosis. The study reveals that Marek’s Disease infection in broiler chicken tends to be mild i.e. infiltration of neoplastic cells (lymphoid, pleomorphic in proventriculus, intestine, spleen, livers and bursa of fabricius. In addition to this, there were mild non-supurative inflammation in heart, lung, peripheral nerve and brain, as well as a severe demyelination in brain. It is concluded that the histopthological features confirm the diagnosis of Marek’s Disease.

    Butterflies and moths are found in all terrestrial environments and require efforts for a better understanding of its mega-diversity. These taxa have been the subject of several studies involving phylogeny, ecology and environmental impacts. Nevertheless, several areas in the tropics remain unexplored, resulting in gaps in the taxonomic composition and distribution of butterflies in endemic environments. Therefore, a survey of the butterfly fauna of the Bodoquena Plateau in Brazil was conducted. This area consists of tropical Atlantic Forests, with marginal influences of Savannah, Chaco and Pantanal. Sampling was carried out in 20 locations using Van Someren Rydon traps and insect nets between November 2009 and April 2015. Active collection of individuals was conducted from 9:00 to 17:00h, totaling 240 hours of sampling effort. In total, we registered 768 individuals belonging to 146 species of 98 genera, six families and 18 subfamilies. Nymphalidae was the richest family (84 species), followed by Hesperiidae (22 species), Riodinidae (14 species), Pieridae (12) Papilionidae (11 species) and Lycaenidae (five species). We sampled 239 nymphalids in traps, with 48 species, 30 genera, 15 tribes and five subfamilies. The most common species were Eunica macris (Godart, 1824), Dynamine artemisia (Fabricius, 1793) and Memphis moruus (Fabricius, 1775). Therefore, this study contributes to the knowledge of the Neotropical butterfly diversity and distribution, providing 37 new records and supporting the use of wildlife inventories as important tools for the knowledge of tropical forests biodiversity and conservation.

    Mimicking insect flights were used to design and develop new engineering materials. Although extensive research was done to study various aspects of lfying insects. Because the detailed mechanics and underlying principles involved in insect lfights remain largely unknown. A systematic study was carried on insect lfights by using a combination of several advanced techniques to develop new models for the simulation and analysis of the wing membrane and veins of three types of insect wings, namely dragonfly (Pantala lfavescensFabricius), honeybee (Apis cerana cerana Fabricius) and lfy (Sarcophaga carnaria Linnaeus). In order to gain insights into the lfight mechanics of insects, reverse engineering methods were used to establish three-dimensional geometrical models of the membranous wings, so we can make a comparative analysis. Then nano-mechanical test of the three insect wing membranes was performed to provide experimental parameter values for mechanical models in terms of nano-hardness and elastic modulus. Finally, a computational model was established by using the ifnite element analysis (ANSYS) to analyze and compare the wings under a variety of simpliifed load regimes that are concentrated force, uniform line-load and a torque. This work opened up the possibility towards developing an engineering basis for the biomimetic design of thin solid iflms and 2D advanced engineering composite materials.

    The experiment was conducted with the objective of studies on effects of zinc toxicity on lymphoid organs by the methods of experimental pathology and flow cytometry (FCM). 200one-day-old Avian broilers were divided into four groups randomly, and fed on diets as follows: controls (Zn 100mg kg-1)and zinc toxic (Zn 1 500mg kg-1, zinc toxic group Ⅰ; Zn 2 000 mg kg-1, zinc toxic group Ⅱ; Zn 2 500 mg kg-1, zinc toxic group Ⅲ) for seven weeks. The weight and growth index of the thymus, spleen and bursa of Fabricius were reduced in both zinc toxic group Ⅱ and zinc toxic group Ⅲ when compared with those of control group. The G0/G1 phase of the cell cycles of the lymphoid organs was higher, and S, G2+M phases lower in zinc toxic groups Ⅱ and Ⅲ than in control group. Lymphocytes were depleted and degenerate in the lymphoid organs. The reticular cells of the bursa of Fabricius proliferated and the reticular cells of the thymus were also degenerate and necrotic,particularly in zinc toxic groups Ⅱ and Ⅲ. The results demonstrated that more than 1 500 mg kg-1 impaired the progression of lymphocytes from the G0/G1 phase to S phase obviously, inhibited the development of lymphoid organs and caused marked pathological changes in the lymphoid organs. Potential mechanisms underlying these observations are also discussed.

    In 2008, clinical cases of short beak and dwarfism syndrome (SBDS) caused by Muscovy duck parvovirus (MDPV) infection were found in mule duck and Taiwan white duck farms in Fujian, China. A MDPV LH strain causing duck SBDS without tongue protrusion was isolated in this study. Phylogenetic analysis show that the MDPV LH strain was clustered together with other MDPV strains, but divergent from GPV isolates. Two major fragment deletions were found in the inverted terminal repeats (ITR) of MDPV LH similar to the ones in the ITR of MDPV GX5, YY and SAAS-SHNH strains. To investigate the pathogenicity of the MDPV LH strain, virus infection of young mule ducks was performed. The infected ducks showed SBDS symptoms including retard growth and shorten beaks without tongue protrusion. Atrophy of thymus, spleen and bursa of Fabricius was identified in the infected ducks. The results show that MDPV LH strain is moderately pathogenic to mule duck, leading to occurrence of SBDS. As far as we know, it is the first study showing that SBDS without tongue protrusion, and atrophy of thymus, spleen and bursa of Fabricius possibly associated with immunosuppression were found in the MDPV-infected ducks. The established duck-MDPV-SBDS system will help us to further work on the virus pathogenesis and develop efficacious vaccine against MDPV infection. Copyright © 2017. Published by Elsevier Ltd.

    Infection with J group avian leukosis virus (ALV-J) can result in immunosuppression and subsequently increased susceptibility to secondary infection. The innate immune system is the first line defense system in prevention of further bacterial and viral infections. Cytokines play key roles in the innate immune system. In this study, we used RT-qPCR technology to test the cytokine mRNA expression levels in various immune tissues, including the spleen, bursa of fabricius and cecal tonsil, in the days following ALV-J infection. The results indicated that in the infected group, the expression levels of interleukin-6 (IL-6), IL-18, interferon-α (IFN-α) and IFN-γ significantly increased in the spleen and reached peak levels that were thousandfolds higher than baselines at 9-12 days post-infection (d.p.i.). The levels in the bursa of fabricius slightly increased, and the levels in the cecal tonsil were not significantly altered. Moreover, the pattern of the expression of these three cytokines in the spleens of the infected group was similar to the pattern of viremia of this group. These results suggest that the spleen plays an important role in the interaction between ALV-J infection and the innate immune system. This study contributes to the understanding of innate immune responses to ALV-J infection and also elucidates the mechanisms of the pathogenicity of ALV-J in chickens.

    Full Text Available The trap-nesting bees of Guaribas Biological Reserve were studied during one year. Three areas with different vegetation types were sampled, open savanas, closed forest, and a mosaic of these two types. Twelve species of trap-nesting bees were observed, four of which are parasites. The most abundant species were Centris tarsata (Smith, 1879, C. analis (Fabricius, 1804, Tetrapedia diversipes KJug, 1810, and Mesocheira bicolor (Fabricius, 1804. Nesting of Centris tarsata and Mesocheira bicolor occurred mainly during the dry season, while Centris analis and Tetrapedia diversipes did not show any seasonal preferences. Mesocheira bicolar occurred only in the nests of C. tarsata, parasitizing more than 50% of the nests and representing 23.2% of the individuais emerged in the host nests. The mosaic area yielded a greater abundance and diversity. Comparing the sampling methods of trap-nests and entomological nets, conducted simultaneously in the same area, in relation to diversity of trap nesting bees, it was observed a great similarity in terrns of composition and differences of abundance in species sampled. Some hypothesis are discussed to explain a reason for the greater diversity and abundance of the mosaic area in relation to the other areas.

    The effect of organic trace mineral supplementation on performance, intestinal morphology, immune organ weights (bursa of Fabricius and spleen), expression of innate immune response related genes, blood heterophils/lymphocytes ratio, chemical metabolic panel, natural antibodies (IgG), and oxidative stress of broiler chickens was studied. A total of 1,080 day-old male broilers were assigned to 1 of 3 dietary treatments, which included basal diet with Monensin (control), control diet supplemented with bacitracin methylene disalicylate (BMD), and BMD diet supplemented with organic trace minerals (OTM). No difference in feed conversion ratio was observed among treatments; ileum histomorphological analysis showed a lower crypt depth, higher villi height/crypt depth ratio, and lower villi width in the OTM treatment compared to control. Furthermore, OTM treatment resulted in higher uric acid and lower plasma malondehaldehyde (MDA), indicating lower oxidative stress. Gene expression analysis showed that OTM treatment resulted in up-regulations of TLR2 bin the ileum, and TLR2b, TLR4, and IL-12p35 in the bursa of Fabricius, and down-regulation of TLR2b and TLR4 in the cecal tonsils. In the spleen, OTM treatment resulted in up-regulation of IL-10. In conclusion, OTM supplementation to broiler diets may have beneficial effects on intestinal development, immune system status, and survival by improving ileum histomorphological parameters, modulation of Toll-like receptors and anti-inflammatory cytokines, and decreasing level of MDA, which in conjunction could enhance health status.

    We study the eigenvector problem in homogeneous superintegrable chiral Potts model (CPM) by the symmetry principal. Using duality and degeneracy symmetries of $\\tau^{(2)}$-model, we construct the complete eigenvectors in superintegrable CPM for an arbitrary Onsager sector. By duality in CPM, the Bethe state and the Fabricius-McCoy current for a sector in $\\tau^{(2)}$-model are constructed by employing algebraic-Bethe-ansatz techniques on its equivalent XXZ chain. The algebra-generators for the $sl_2$-loop-algebra symmetry of a $\\tau^{(2)}$-sector are determined by the Fabricius-McCoy current. Together with the loop-algebra and Onsager-algebra symmetries, we obtain the local-vector representation of $\\tau^{(2)}$- and CPM-eigenvectors. In this paper we also present the complete and precise constraints of quantum numbers for $\\tau^{(2)}$-sectors. By examining the relationship between solutions of Bethe equations, a new reflective symmetry, besides the duality relation, is found in the superintegrable $\\tau^{(2)}...

    Full Text Available Developmental biology, polymorphism and ecological aspects of Stiretrus decemguttatus (Hemiptera, Pentatomidae, an important predator of cassidine beetles. Stiretrus decemguttatus is an important predator of two species of cassidine beetles, Botanochara sedecimpustulata (Fabricius, 1781 and Zatrephina lineata (Fabricius, 1787 (Coleoptera, Cassidinae, on the Marajó Island, Brazil. It attacks individuals in all development stages, but preys preferentially on late-instar larvae. Its life cycle in the laboratory was 43.70 ± 1.09 days, with an egg incubation period of six days and duration from nymph and adult stages of 16.31 ± 0.11 and 22.10 ± 1.67 days, respectively. The duration of one generation (T was 12.65 days and the intrinsic population growth rate (r 0.25. These data reveal the adjustment of the life cycle of S. decemgutattus with those of the two preys, but suggest greater impact on Z. lineata. However, no preference over cassidine species was shown in the laboratory. Up to 17 different color patterns can be found in adults of S. decemguttatus, based on combinations of three basic sets of color markings. Some of them resemble the markings of chrysomelids associated with Ipomoea asarifolia (Convolvulaceae and are possibly a mimetic ring. Three color patterns were identified in nymphs, none of which was associated with any specific adult color pattern.

    Abstract. The aim of this study was to identify the treehoppers diversity associated with cocoa plantation and to determine the seasonality of the most common species in two shaded areas, in the municipality of Linhares, Espirito Santo State, Brazil. For the sampling, twelve yellow-tray traps were randomly set in each area, spaced from one another in 30 m., placed on wooden stakes at a height of 1.0 m. above ground level. Weekly the collected material was taken during August/2011 to July/2012. Also samples of fruits, branches and leaves containing postures, nymphs, and adults of the treehoppers were collected and maintained in the laboratory for the eventual emergence of parasitoids and cataloging of the species. Through the traps were collected 16,094 exemplars of treehoppers belonging to 30 species, of which, 58.7 % in the first area (70 % shade and 41.3 % in the second area (60 % shade. The most abundant species was Horiola picta (Coquebert comprising 87.2 % of the total collection. Cocoa trees are confirmed to be the host plant of H. picta, Membracis tectigera Olivier, Membracis dorsata Fabricius, Membracis mimica Walker, Anobilia sp., Phormophora maura (Fabricius, Leioscyta pulchella Funkhouser and Enchenopa squamigera (Linnaeus.

    Full Text Available Hermeuptychia intricata Grishin, sp. n. is described from the Brazos Bend State Park in Texas, United States, where it flies synchronously with Hermeuptychia sosybius (Fabricius, 1793. The two species differ strongly in both male and female genitalia and exhibit 3.5% difference in the COI barcode sequence of mitochondrial DNA. Setting such significant genitalic and genotypic differences aside, we were not able to find reliable wing pattern characters to tell a difference between the two species. This superficial similarity may explain why H. intricata, only distantly related to H. sosybius, has remained unnoticed until now, despite being widely distributed in the coastal plains from South Carolina to Texas, USA (and possibly to Costa Rica. Obscuring the presence of a cryptic species even further, wing patterns are variable in both butterflies and ventral eyespots vary from large to almost absent. To avoid confusion with the new species, neotype for Papilio sosybius Fabricius, 1793, a common butterfly that occurs across northeast US, is designated from Savannah, Georgia, USA. It secures the universally accepted traditional usage of this name. Furthermore, we find that DNA barcodes of Hermeuptychia specimens from the US, even those from extreme south Texas, are at least 4% different from those of H. hermes (Fabricius, 1775—type locality Brazil: Rio de Janeiro—and suggest that the name H. hermes should not be used for USA populations, but rather reserved for the South American species. This conclusion is further supported by comparison of male genitalia. However, facies, genitalia and 2.1% different DNA barcodes set Hermeuptychia populations in the lower Rio Grande Valley of Texas apart from H. sosybius. These southern populations, also found in northeastern Mexico, are described here as Hermeuptychia hermybius Grishin, sp. n. (type locality Texas: Cameron County. While being phylogenetically closer to H. sosybius than to any other

    Weaver ants (Oecophylla smaragdina Fabricius) have been increasingly used as biocontrol agents of insect pests and as insect protein for human food and animals. For either of these purposes, mature ant colonies are essential. However, for a newly established colony to develop to a suitable mature...... size takes 3 years, which is too long. Multiple queens and non-nestmate pupae transplantation may be the way to boost early colony growth. An experiment on newly founded O. smaragdina colonies with 2, 3 and 4 founding queens together with transplantation of 0, 30 and 60 non-nestmate pupae from a mature...... donor colony was conducted in 2010 at Darwin, Australia. The survival rates of the imago workers from transplanted pupae ranged between 73 - 97%, suggesting that queens in incipient colonies accepted foreign pupae. Colony size was positively related to the number of founding queens. Compared...

    2014-04-01

    A new species of the alpheid shrimp genus Athanas Leach, 1814 is described based on a single specimen, an ovigerous female from Nha Trang Bay, Vietnam. Athanas manticolus sp. nov. differs from all other species of Athanas by the presence of a small post-rostral tubercle, combined with a minutely toothed rostrum, reduced extra-corneal teeth, and the absence of infra-corneal and supra-corneal teeth. In addition, the new species is characterised by its unique colour pattern, particularly by the red chromatophores disposed in randomly oriented, short, narrow streaks. As its name suggests, A. manticolus sp. nov. is commensally associated with the burrows of the nannosquillid mantis shrimp Bigelowina phalangium (Fabricius, 1798).

    Chrysomya megacephala (Fabricius) is a forensically important fly that is found throughout the tropics and subtropics. We calculated the accumulated development time and transition points for each life stage from eclosion to adult emergence at five constant temperatures: 15, 20, 25, 30, and 35 °C. For each transition, the 10th, 50th, and 90th percentiles were calculated with a logistic linear model. The mean transition times and % survivorship were determined directly from the raw laboratory data. Development times of C. megacephala were compared with that of two other closely related species, Chrysomya rufifacies (Macquart) and Phormia regina (Meigen). Ambient and larval mass temperatures were collected from field studies conducted from 2001–2004. Field study data indicated that adult fly activity was reduced at lower ambient temperatures, but once a larval mass was established, heat generation occurred. These development times and durations can be used for estimation of a postmortem interval (PMI).

    Antennae are among the most elaborate sensory organs in adult flies, and they provide rich information for phylogenic studies. The antennae of five out of eight species of Gasterophilus Leach (G. haemorrhoidalis (Linnaeus), G. intestinalis (De Geer), G. nasalis (Linnaeus), G. nigricornis (Loew) and G. pecorum (Fabricius)), were examined using scanning electron microscopy. The general morphology, including distribution, type, size, and ultrastructure of antennal sensilla were presented, and the definition of auriculate sensilla and sensory pits were updated and clarified. Eighteen antennal characters were selected to construct the first species-level phylogeny of this genus. The monophyly of Gasterophilus was supported by the presence of coeloconic sensilla III on the antennal arista. The species-level cladogram showed G. pecorum branching off at the base, and the remaining species forming the topology (G. intestinalis+ (G. haemorrhoidalis+ (G. nasalis+ G. nigricornis))). Our research shows the importance of the antennal ultrastructure as a reliable source for phylogenetic analysis. PMID:27703229

    Full Text Available Although common in Brazil, the biology of the fire ant Solenopsis saevissima (Smith is still poorly studied. Larval descriptions are useful to genus-level ant systematics and sometimes to species-level taxonomy. This study presents a detailed description of juveniles of S. saevissima from Brazil, which were compared with Brazilian specimens of Solenopsis invicta Buren, Solenopsis geminata (Fabricius, and Solenopsis altipunctata Pitts. Different larval instars were separated by diagnostic morphological traits which were confirmed by observing moults. Reproductive larvae could be easily sorted by their distinctive body dimensions and shape. Contrary to previous reports on this species, the larvae of S. saevissima proved to be generally identical to those of S. invicta, while a few specimens resembled those of other close species, such as Solenopsis megergates Trager. Mature larvae thus presented considerable intraspecific variation in some characters recently proposed to aid fire ant species separation (morphology of head hairs.

    The bursa of Fabricius (BF) is the key humoral immune organ unique to birds, and is critical for early B-lymphocyte proliferation and differentiation. However, the molecular basis and mechanisms through which the BF regulates B cell development are not fully understood. In this study, we isolated and identified a new bursal peptide (BP8, AGHTKKAP) by RP-HPLC and MALDI-TOF-MS. BP8 promoted colony-forming pre-B formation, bound B cell precursor, regulated B cell development in vitro as well as in vivo, upstream of the EBF-E2A-Pax5 regulatory complex and increased immunoglobulin secretion. These data revealed a bursal-derived multifunctional factor BP8 as a novel biomaterial which is essential for the development of the immune system. This study elucidates further the mechanisms involved in humoral immune system and has implications in treating human diseases.

    We attempted a DNA comet assay under alkaline conditions to verify the irradiation treatment of pests. Lasioderma serricorne (Fabricius) were chosen as test insects and irradiated with gamma rays from a 60Co source at 1 kGy. We conducted the comet assay immediately after irradiation and over time for 7 day. Severe DNA fragmentation in L. serricorne cells was observed just after irradiation and the damage was repaired during the post-irradiation period in a time-dependent manner. The parameters of the comet image analysis were calculated, and the degree of DNA damage and repair were evaluated. Values for the Ratio (a percentage determined by fluorescence in the damaged area to overall luminance, including intact DNA and the damaged area of a comet image) of individual cells showed that no cells in the irradiated group were included in the Ratiocomet assay under alkaline conditions, combined with comet image analysis, can be used to identify irradiation history.

    Richter hernia (partial enterocele) is the protrusion and/or strangulation of only part of the circumference of the intestine's antimesenteric border through a rigid small defect of the abdominal wall. The first case was reported in 1606 by Fabricius Hildanus. The first definition of partial enterocele was given by August Gottlieb Richter in 1785. Sir Frederick Treves discriminated it from Littre hernia (hernia of the Meckel diverticulum). More often these hernias are diagnosed in the sixth and seventh decades of life. They comprise 10 per cent of strangulated hernias. Their common sites are the femoral ring, inguinal ring, and at incisional trauma. The most-often entrapped part of the bowel is the distal ileum, but any part of the intestinal tube may be incarcerated. These hernias progress more rapidly to gangrene than other strangulated hernias, and obstruction is less frequent. The gold standard technique for repair is the preperitoneal approach, followed by laparotomy and resection if perforation is suspected.

    Early body condition may be important for adult behavior and fitness, and is impacted by a number of environmental conditions and biotic interactions. Reduced fecundity of adult females exposed to larval competition may be caused by reduced body condition or shifts in relative body composition, yet these mechanisms have not been well researched. Here, body mass, body size, scaled body mass index, and two body components (water content and lean dry mass) of adult Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae: Bruchinae) females exposed to larval competition or reared alone were examined. Experimental females emerged at significantly smaller body mass and body size than control females. Additionally, scaled body mass index and water content, but not lean dry mass, were significantly reduced in experimental females. To our knowledge, these are the first results that demonstrate a potential mechanism for previously documented direct effects of competition on fecundity in female bruchine beetles.

    A new genus, Teramnonotus n. gen., is erected for Elamena gordonae Monod, 1956. The new genus includes two new species, T. johnlucasi n. gen., n. sp. and T. monodi n. gen., n. sp., described herein from eastern Australia (Queensland) and the southwestern Atlantic (Brazil), respectively. Teramnonotus n. gen. superficially resembles Elamena H. Milne Edwards, 1837, and Trigonoplax H. Milne Edwards, 1853, of which it can be easily distinguished by a combination of characters: eyes and ocular peduncle, rostrum, carapace, thoracic sternite 8 and thoracic pleurite 8, and the inhalant water openings. The validity of the obscure species Elamena mexicana H. Milne Edwards, 1853, is not supported and it is synonymised with Halicarcinus planatus (Fabricius, 1775).

    Full Text Available The objective of the present study was to assess the development of broiler chicks during the first week post-hatching when reared at three different environmental temperatures. A total of 480 day-old chicks were placed in three environmentally controlled rooms (20, 25 and 35°C from 1 to 7 days of age. Body weight gain, feed and water intake, as well as liver, gizzard, heart, yolk sac and bursa of Fabricius weights were measured daily. Tibia and femur bones were weighed and their length and width (medial diameter were also obtained. The chicks reared at 20º C had lower weight gain and ingested less food than chicks reared at 25°C and less water than chicks kept at 35°C. Relative weights of the liver, heart, and gizzard were affected by environmental temperature, whereas yolk sac and bursa of Fabricius relative weights were not. The data showed that all bone parameters increased with bird age. Environmental temperature did not affect tibia or femur width, however a significant increase in bone weight and length occurred with increasing environmental temperature. These results indicate that brooding temperature of 20°C during the first seven days post-hatching was stressful decreasing broiler bone development and reducing chicks body weight.O presente trabalho teve como objetivo estudar o efeito de diferentes temperaturas-ambiente durante a primeira semana de vida de pintos de corte sob parâmetros zootécnicos, desenvolvimento visceral e crescimento ósseo.

    Evidence suggesting polyphyly of the traditionally recognised tick genus Aponomma Neumann, 1899 is summarized. Continued recognition of this genus in its current concept leaves a polyphyletic genus Aponomma and a paraphyletic genus Amblyomma Koch, 1844. To improve the correlation between our understanding of phylogenetic relationships in metastriate ticks and their classification, a few changes in classification are proposed. The members of the 'indigenous Australian Aponomma' group (sensu Kaufman, 1972), A. auruginans Schulze, 1936, A. concolor Neumann, 1899, A. glebopalma Keirans, King & Sharrad, 1994, A. hydrosauri (Denny, 1843) and A. undatum (Fabricius, 1775), are transferred to Bothriocroton Keirans, King & Sharrad, 1994, which is raised to full generic rank. The remaining members of Aponomma are transferred to Amblyomma. Uncertainty remains on relationships of Bothriocroton to other metastriate lineages and on the systematic position of the two species formerly included in the 'primitive Aponomma' group, A. elaphense Price, 1959 and A. sphenodonti Dumbleton, 1943.

Lepidopterology is not a static concept, but a science which is constantly evolving as a result of new knowledge often coming from different disciplines. This list may therefore be seen as a sort of key, because it is our best guess at the correct names...... species with an occurrence far from Denmark in general should be considered as migrants and not as introduced. In some cases there are arguments suggesting that this is probable (e.g. several records of a certain species in the same period in Denmark or in our neighbouring countries or specific...... in the literature are cited as published in either 1780 or in 1802.

    A new C-methylated flavone glycoside, 5,7-dihydroxy-3-methoxy-6-C-methylflavone 8,4'-di-O-β-D-glucopyranoside (1), was isolated from the twigs and leaves of Picea neoveitchii Mast, together with eight known compounds, 5,7,8,4'-tetrahydroxy-3-methoxy-6-methylflavone 8-O-β-D-glucopyranoside (2) kaempferol 3,4'-di-O-β-D-glucopyranoside (3), apigenin 7-O-β-D-glucopyranoside (4), tiliroside (5), massonianoside B (6), umbeliferone 7-O-β-D-glucopyranoside (7), dihydroconiferin (8) and gleditschiaside A (9). Their structures were elucidated on the basis of analyses of spectroscopic data. Compound 1 showed moderate antifungal activity against tested plant pathogens (Pyricularia grisea (Cooke) Sacc., Sclerotium rocfsii Sacc. and Alternaria mali Roberts), however, compounds 2 and 5 had obvious inhibitory effect against S. rocfsii and A. mali, respectively. Compounds 1, 2, 3 and 9 also exhibited potent cytotoxicity against Spodoptera litura Fabricius cells.

    This study aimed to evaluate the effect of dietary ochratoxin, in the presence or absence of aluminosilicate, on the histology of the bursa of Fabricius, liver and kidneys, and on the humoral immune response of broilers vaccinated against Newcastle disease virus. The exposure of birds to 2 p.p.m. ochratoxin, in the presence or absence of aluminosilicate, reduced their humoral immune response and the number of mitotic cells in the bursa. The relative weight of the livers of the birds exposed to this toxin was increased and, microscopically, there was hepatocyte vacuolation and megalocytosis with accompanying hyperplasia of the biliary epithelium. The kidneys showed hypertrophy of the renal proximal tubular epithelium, with thickening of the glomerular basement membrane. Aluminosilicate did not ameliorate the deleterious effects of the ochratoxin.

    Abstract Most species of Parnara and Pelopidas (Hesperiidae) are important pests of rice. In this study, the antennal morphology, types of sensilla, and their distribution of four skipper butterflies, including Parnara guttata (Bremer & Grey), Pa. bada (Moore), Pelopidas mathias (Fabricius) and Pe. agna (Moore), were observed using a scanning electron microscope. Six distinct morphological types of sensilla were found on the antennae of all of these species: sensilla squamiformia, sensilla trichodea, sensilla chaetica, sensilla auricillica, sensilla coeloconica, and Böhm sensilla. The sensilla trichodea are the most abundant sensilla among the four skipper butterflies, and the sensilla auricillica are confirmed on the antennae of butterflies for the second time. In addition, the possible functions of these sensilla are discussed in the light of previously reported lepidopteran insects, which may provide useful information for further study of the function of these antennal sensilla and for related pests control by applying sex pheromones.

    @@ Photonic bandgap (PBG) materials are periodic com- posites of dielectric materials in which electromagnetic waves of certain frequency range cannot propagate in any or a special direction. Recently, there has been great inter- est in synthetic PBG materials due to their ability in ma- nipulation of photons. Since 500 million years ago, the natural world has been exploiting photonic structures for specific biological purposes[1]. Different types of biologi- cal PBG materials have been discovered in recent years, such as the one-dimension PBG structure in the sea mouse Aphrodita[2], and the fruits Elaeocarpus[3,4]; two-dimension PBG structure in the male peacock Pavo muticus feathers[5], Indonesian male Papilio palinurus butterfly[6], Thaumantis diores butterfly[7] and the male Ancyluris meliboeus Fabricius butterflies[8]; and three-dimension PBG structure in the weevil Pachyrhynchus argus[9].

    Full Text Available The woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae was introduced in Brazil in 1988 and became the main pest in pine plantations. It has spread to about 1.000.000 ha, at different population levels, in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo and Minas Gerais. Control is done mainly by using a nematode, Deladenus siricidicola Bedding (Nematoda: Neothylenchidae. The evaluation of the efficiency of natural enemies has been difficult because there are no appropriate sampling systems. This study tested a hierarchical sampling system to define the sample size to monitor the S. noctilio population and the efficiency of their natural enemies, which was found to be perfectly adequate.

    Full Text Available Analysis of antibiosis resistance to common cutworm (Spodoptera litura Fabricius in soybean (Glycine max (L. Merr. has progressed significantly, but the immediate cause remains unknown. We performed quantitative trait loci (QTL analysis of pubescence density and plant development stage because these factors are assumed to be the immediate cause of resistance to cutworm. The QTLs for pubescence appeared to be identical to the previously detected the Pd1 and Ps loci controlling pubescence density. We found no candidate loci for flowering time QTLs, although one could be identical to the gene governing the long-juvenile trait or to the E6 loci controlling maturity. None of the QTLs overlapped with the QTLs for antibiosis resistance.

    Full Text Available The Double-branded Blue Crow Euploea sylvester hopei C & R Felder, 1865 (Lepidoptera: Nymphalidae: Danainae is a rare member of the genus Euploea Fabricius, 1807 and ranges through South Asia, Southeast Asia and parts of Australia. During the course of a field visit to the Park, the author recorded an individual of Euploea sylvester hopei on 14 ‎June ‎2014 at the Rampahar balurchar (22°30'29.57" N and 92°11'36.60" E in Kaptai National Park of Rangamati District, Bangladesh (Image 1. The male individual was caught at 12:40+6GMT and photographed (Image 2−4 . Two other individuals of the subspecies were observed during the field visit period, suggesting that this is not a common species in that area. However, no specimens were collected, due to lack of collection permits.

    We report two separate naturally occurring cases of fatal herpesviral disease in Cooper's Hawks (Accipiter cooperii). Gross lesions included splenomegaly and hepatomegaly, with diffuse pale mottling or scattered small white foci. Histologic lesions included splenic and hepatic necrosis associated with eosinophilic intranuclear inclusion bodies characteristic of herpesvirus. In one case, necrosis and inclusions were also noted in bone marrow, thymus, bursa of Fabricius, thyroid gland, parathyroid gland, ceca, and the enteric system. Transmission electron microscopy demonstrated viral particles typical of herpesvirus within hepatocyte nuclei and budding from the nuclear membrane. Herpesviral DNA was amplified via polymerase chain reaction (PCR) of paraffin-embedded liver and spleen, and sequence data were consistent with columbid herpesvirus-1, an alphaherpesvirus of Rock Pigeons (Columba livia). PCR results provide evidence that this disease is transmitted to raptors via Rock Pigeons, most likely through ingestion of Rock Pigeons as prey.

    By adding different amount of zinc into the artificial medium of the insect larvae, the zinc-induced apoptosis of the larvae haemocytes of the herbivorous insect Spodoptera litura Fabricius was investigated with flow cytometer. The results showed that the increase of zinc dose in the artificial feed led to the accumulations of zinc in the larval hemolymph and fat body, and more zinc was accumulated in fat body than in hemolymph. The apoptosis of hemocytes was significantly induced at high zinc concentration (1000 mg·kg-1) in the insect diet, and the apoptosis rate was 63.63%, which was remarkably higher than that at control and lower concentrations (50-500 mg·kg-1). This suggests that the high dose of zinc in the artificial diet of S. Litura larvae could induce the apoptosis of the larval hemocytes of S. Litura.

    2002-01-01

    We present spectroscopic measurements of the 23 new candidate members of the TW Hydrae Association from Makarov & Fabricius (2000). Based on Halpha and Li 6708 A strengths together with location on a color-magnitude diagram for Hipparcos TWA candidates, we found only three possible new members (TYC 7760-0835-1, TYC 8238-1462-1, and TYC 8234-2856-1) in addition to the already known member, TWA 19. This eliminated most of the candidates more distant than 100 pc. Three Tycho stars, almost certainly members of the Lower Centaurus Crux association, are the most distant members of the TWA. A claim of isotropic expansion of TWA has to be re-evaluated based on our new results. Generally, one cannot identify new members of a diffuse nearby stellar group based solely on kinematic data. To eliminate interlopers with similar kinematics, spectroscopic verification is essential.

    Full Text Available Eriopis connexa (Germar (Coleoptera: Coccinellidae occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller (Lepidoptera: Pyralidae and Spodoptera frugiperda (J. E. Smith (Lepidoptera: Noctuidae frozen for one day, fresh eggs of Diatraea saccharalis (Fabricius (Lepidoptera: Pyralidae, S. frugiperda newly-hatched caterpillars, nymphs of Rhopalosiphum maidis (Fitch and Schizaphis graminum (Rondani (Hemiptera: Aphididae. Duration of larva, pupa and larva to adult stages differed among prey offered, whereas the prepupa stage was similar. Larva, pupa, prepupa and larva to adult viabilities were equal or major of 87.5% in all prey, except for larva fed on newly-hatched larvae of S. frugiperda. Eriopis connexa has good adaptation to different prey corroborating its polyphagous feeding habit, which evidences the potential of this natural enemy for controlling corn and sorghum pests.

    We present an updated checklist of the ladybird beetle fauna of New Caledonia. Fifty species have been tracked from literature and collections, but six should be removed from the list as they represent false records, invalid or unestablished species: Coccinella boletifera Fauvel, Harmonia conformis (Boisduval), Menochilus duodecimpunctatus (Fauvel), Micraspis lineola (Fabricius), Orcus australasiae Boisduval, and Curinus coeruleus (Mulsant). After our investigations, the current described ladybird beetle fauna totals 44 named species, belonging to 18 valid genera. The endemism rate is 47.7% (21 species), with one endemic subgenus, Scymnus (Caledonus). Based on comparisons of the coccinellid faunas of surrounding regions, the New Caledonian fauna has affinities with Australia and Papua New Guinea more than with the rest of the Pacific area. At least 19 species (43.2%) seem to have been introduced by human activities (either deliberately or accidentally).

    In forensic entomology, larval rearing usually includes the presence of biological contaminants including scuttle flies (Diptera: Phoridae). Scuttle flies are recognized as forensically important insects and have been reported causing nuisance and contamination in laboratory environments. This paper reports for the first time the finding of multiple scuttle fly species affecting colonies of third instar larvae of the Oriental latrine blowfly, Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae), reared indoors at the Forensic Science Simulation Site, Universiti Kebangsaan Malaysia. Adult scuttle flies were discovered inside a rearing container after the emergence of adult C. megacephala., The scuttle fly species are Megaselia scalaris (Loew), M. spiracularis Schmitz and Puliciphora borinquenensis (Wheeler). Notes on the life history and biology of these species are discussed herein.

Of the two types of food offered, the ants ingested 76% pure sucrose and 24% insect prey (dry weights) leading to ECI’s of 29% and 39% including brood only or brood plus imago gain, respectively. Based on Thai sugar and protein food costs and ant brood......Oecophylla ants are sold at high prices on several commercial markets as a human delicacy, as pet food or as traditional medicine. Currently markets are supplied by ants collected from the wild; however, an increasing interest in ant farming exists as all harvest is easily sold and as ant farming...... can be combined with the use of the ants in biological control programmes in tropical plantations where pest insects are converted into ant biomass. To assess the cost-benefits of ant farming based on artificial feeding, food consumption and food conversion efficiency (ECI) of Oecophylla smaragdina...
