    Abstract. This study aims the registration of the association between Cerambycidae and Vochysia divergens Pohl (Vochysiaceae, typical plant species of the northern region of the Pantanal of Mato Grosso that besides forming monodominant stands and is considered a weed of fields and pastures in this region. In this study, branches and trunks of this specie were collected over one year (July/1999 - June/2000 and lab monitored for density and emergency time evaluation of Cerambycidae. As results 277 individuals were sampled, representing three species of Cerambycidae, Psapharochrus bivittis (White, Luscosmodicum beaveari Martins and Neoeme bouvieri Gounelle. In addition to registration of the association, it was noted that the emergence peak of Cerambycidae coincides with the beginning of flood and high water period in northern Pantanal, showing the synchronization between the biological development of this species and the hydrological cycle in this region

A ocorrência e os danos provocados pelas larvas foi verificado “in loco”, em cada uma das plantas do pomar, contando-se as plantas e os galhos atacados, o número de larvas por galho e o diâmetro destes. Foi observado também o ciclo biológico em condições de campo e o número de ovos por fêmea dissecada. A postura é feita em fendas no galho. A média de ovos obtidos de 11 fêmeas dissecadas foi de 83, máximo de 132 e mínimo de 63. O ciclo biológico de ovo/adulto foi de 10 meses. Após a eclosão as larvas constroem galeria na região subcortical, atacando galhos com diâmetro variando entre 2 a 6 cm. A maioria dessas galerias quase atinge um andamento em torno do galho, o que provocou o secamento ou a quebra de 41,3 % dos galhos, agravado pela ação dos ventos e o peso dos frutos. A tangerina cravo apresentou 35% de plantas atacadas, baianinha 27%, natal 24%, tangor sabará 20% e tangerina rio 13%. Não foi constatada a presença de larvas no limão cravo.

  1. Medically important beetles (insecta: coleoptera of Iran

    Directory of Open Access Journals (Sweden)

    MR Nikbakhtzadeh

    2008-01-01

    Full Text Available This study focused on coleopteran species that are responsible for the emergence of recent cases of dermatological manifestations in Iran. To the best of our knowledge, five species of the family Meloidae and nine species of the genus Paederus are by far the only beetles recognized as medically important in Iran. The staphylinids consists of Paederus ilsae, P. iliensis, P. fuscipes, P. kalalovae, P. balcanicus, P. lenkoranus, P. littoralis, P. carpathicus, P. nigricornis, while the meloids are Mylabris impressa, M. guerini, Muzimes iranicus, Alosimus smyrnensis and Epicauta sharpi. Most cases of linear dermatitis in this country occur in areas bordering the Caspian Sea. This problem is caused by beetles of the genus Paederus which are present as adults from mid-April to October with particularly high incidences from May to August. Fars (in southern Iran ranks second in number of cases of insect-induced dermatitis. The third major region in which this type of dermatitis has been recorded is Hamedan Province, in the west of the country. Meloid dermatitis showed its highest severity in 2001, when a considerable number of patients sought medical help in Toyserkan and Nahavand counties. New cases of skin blistering were reported along the Persian Gulf coast and the agent was identified as Epicauta sharpi (Coleoptera: Meloidae. In all these regions, it was observed that recorded cases of lesions coincided precisely with the yearly peaks of the beetles. Paederus fuscipes and P. kalalovae are the predominant species along the Caspian Sea shore. It appears that P. fuscipes is homogeneously distributed throughout the Caspian Sea region while the distribution of the other species is more irregular. Paederus fuscipes is probably the major agent that causes linear dermatitis in northern Iran. Whereas this disease is a rural difficulty in the south, mainly in villages or small towns, it is an urban problem in northern provinces along the Caspian Sea shore

    Fossil mesostigmatid mites are extremely rare. Inclusions assignable to the tortoise mites (Mesostigmata, Uropodina) are described here for the first time from Eocene (ca. 44-49 Ma) Baltic amber. This is the oldest record of Uropodina and documents the first unequivocal amber examples potentially assignable to the extant genus Uroobovella Berlese, 1903 (Uropodoidea: Urodinychidae). Further mites in the same amber pieces are tentatively assigned to Microgynioidea (Microgyniina) and Ascidae (Gamasina), both potentially representing the oldest records of their respective superfamily and family groups. This new material also preserves behavioural ecology in the form of phoretic deutonymphs attached to their carriers via a characteristic anal pedicel. These deutonymphs in amber are intimately associated with longhorn beetles (Coleoptera: Cerambycidae), probably belonging to the extinct species Nothorhina granulicollis Zang, 1905. Modern uropodines have been recorded phoretic on species belonging to several beetle families, including records of living Uroobovella spp. occurring on longhorn beetles. Through these amber inclusions, a uropodine-cerambycid association can now be dated back to at least the Eocene.

  14. Male Megacyllene robiniae (Coleoptera: Cerambycidae) use multiple tactics when aggressively competing for mates.

    2009-04-01

    Adult male Megacyllene robiniae (Förster) (Coleoptera: Cerambycidae) that are paired with a female often are challenged by conspecific males that attempt to displace them. In staged laboratory bouts, challenging males used seven distinct tactics to displace defending males, including wedging their head between the defender and the female (termed wedging), straddling the mated pair and pulling the defender off (prying), pulling it with the mandibles, batting it with the antennae, or pushing, biting, or kicking the defender. Individual challengers attempted as many as six different tactics in a single bout, repeating certain tactics multiple times. They often attempted tactics that were not very effective. For example, prying was one of the most common attempted tactics but was rarely effective. However, few challengers attempted to push defenders off the female, even though that tactic often was effective. Challengers apparently were influenced by context in their choice of particular tactics. For example, males that approached the mated pair from the side were likely to use wedging, whereas those approaching head on were more likely to bat with the antennae. Choice of tactic apparently was not influenced by absolute size of challengers, nor was it strongly influenced by relative size of defenders. However, the effectiveness of tactics varied significantly with relative body size: larger challengers were most successful when prying or pushing, while smaller challengers were most successful when biting and kicking. By using different tactics, relatively small males were as adept as larger males at displacing rivals.

    Full Text Available The woods in Sicily are the result of centuries of anthropogenic activities that have reduced the surface of woodand changed the original composition even with the introduction of alien species to native flora. The value interms of biodiversity of these forests remains, however, high for they are the last refuge areas for many animalsand plant species. This study was conducted within the Ficuzza woods (West Sicily, extended about 5,000hectares on the slopes of limestone-dolomite rock of Busambra (1615 m asl, within which lies the largestremaining forest area in western Sicily. It is an area with a wide diversity of vegetation, represented mainly bynative forests (holm oak, cork oak, deciduous oaks, groups of riparian vegetation, shrubs, bushes, grasslands,and of non-native forest formations (Pinus and Eucalyptus woods. The study on Cerambycidae in this area isfragmented and does not specify a relation the species with the surrounding vegetation. This study wasperformed by choosing among various groups of insects, xylophagous Coleoptera Cerambycidae; existingliterature data and extensive collected field data were reviewed. The analysis was also performed by thecollection of dead wood in order to distinguish the relationship between the plant species and coleoptera. Theresults summarize and supplement the data registered so far, shedding further light on the ecological role ofthis group of insects that are also valid biomarkers of the integrity and complexity of the forest.

  18. Interactions between imidacloprid and Metarhizium brunneum on adult Asian longhorned beetles (Anoplophora glabripennis (Motschulsky)) (Coleoptera: Cerambycidae).

    Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), a longhorned beetle species native to Asia, has been introduced into several North American and European cities. Currently eradication and preventive measures are limited to identifying and destroying infested trees and protecting uninfested trees with trunk or soil-injections of the systemic insecticide imidacloprid. Because entomopathogenic fungi like Metarhizium brunneum Petch have been identified as virulent against these beetles we conducted several tests to determine the compatibility of the two agents in combination. Radial hyphal growth and the sporulation capacity of M. brunneum on Sabouraud dextrose agar with yeast were not significantly affected by the presence of imidacloprid. In a 2×3 factorial experiment investigating interactions between exposure to imidacloprid and M. brunneum we observed no effect of imidacloprid alone on beetle survival when beetles were given a single dose of 10 or 100 ppm compared to control insects. We observed a significant effect of exposure to M. brunneum, and a significant interaction between imidacloprid and M. brunneum representing a synergistic effect of dual treatment. Beetles exposed to the fungus alone lived significantly longer compared to insects treated with a single dose of 100 ppm imidacloprid (9.5 vs. 6.5d). Consumption of striped maple twigs by beetles exposed to imidacloprid, across concentrations, was reduced 48% compared to control insects, where as consumption by M. brunneum-exposed beetles was reduced by 16% over the first 6-days of the test period. Beetles fed 100 ppm imidacloprid consumed 32% less over the first 3d compared to beetles not exposed to imidacloprid and thereafter consumed as much as beetles not fed 100 ppm imidacloprid. M. brunneum-exposed beetles consumed significantly less food than control insects throughout the test period, and beetles treated with imidacloprid produced significantly fewer conidia compared to beetles

    The protein digestive capability oftbe larvae of the longhorn beetle (Oemona hirta,Coleoptera:Cerambycidae,Fabricius,1775) was investigated.This species feeds only on wood where there is a high proportion of vascular tissue.The pH of the midgut,the major digestive organ,was alkaline and protein hydrolysis was maximal at alkaline pH.Use of specific synthetic peptide substrates showed that the major protease activities were the endopeptidases,trypsin and chymotrypsin-like activity,and the exopeptidase,leucine aminopeptidase and the pH curves corresponded to that with protein substrate.Studies using a range ofsefine protease inhibitors as well as specific inhibitors ofmetalloproteases,cysteine proteases and aspartate proteases confirmed a serine protease-based digestive system similar to earlier reports of sapwood-feeding Cerambycids.Control of these insect pests using protease inhibitors is discussed.

    Two saproxylic forest insects, Hylurgus ligniperda (F.) (Coleoptera: Scolytinae) and Arhopalus ferus (Mulsant)(Coleoptera: Cerambycidae), were reared on artificial or natural diet at 15 or 25°C to compare larval growth rates and survival. A significant diet by temperature interaction was observed in the growth of H. ligniperda larvae,which developed faster when reared on natural diet at 15°C, but grew faster and pupated significantly earlier when reared on artificial diet at 25°C. However, H. ligniperda survival by the end of the experiment was low on both diets when reared at 25°C (10.1%, 95% CI: 5.2–15.1%), which suggests that rearing at lower temperatures may be required. A. ferus larvae gained significantly larger body size when reared on artificial diet than on natural diet at both temperatures. Survival of A. ferus reared on artificial diet was significantly lower than larvae reared on natural diet at 25°C. The significant differences between A. ferus larval development rates when reared on artificial and natural diets preclude the use of artificial diet to collect meaningful data to construct temperature development models for ecological comparisons. Artificial diet provided a suitable medium for mass production of individuals for research purposes, e.g., test mortality in response to treatments. However, additional rearing studies are needed to determine whether the larger artificially reared larvae result in adults that are healthier, more productive, and live longer.

  11. Molecular evidence of facultative intraguild predation by Monochamus titillator larvae (Coleoptera: Cerambycidae) on members of the southern pine beetle guild

    Science.gov (United States)

    Schoeller, Erich N.; Husseneder, Claudia; Allison, Jeremy D.

    2012-11-01

    The southern pine bark beetle guild (SPBG) is arguably the most destructive group of forest insects in the southeastern USA. This guild contains five species of bark beetles (Coleoptera: Curculionidae: Scolytinae): Dendroctonus frontalis, Dendroctonus terebrans, Ips avulsus, Ips calligraphus, and Ips grandicollis. A diverse community of illicit receivers is attracted to pheromones emitted by the SPBG, including the woodborers Monochamus carolinensis and Monochamus titillator (Coleoptera: Cerambycidae). These woodborers have been traditionally classified as resource competitors; however, laboratory assays suggest that larval M. carolinensis may be facultative intraguild predators of SPBG larvae. This study used polymerase chain reaction (PCR)-based molecular gut content analyses to characterize subcortical interactions between M. titillator and members of the SPBG. The half-lives of SPBG DNA were estimated in the laboratory prior to examining these interactions in the field. A total of 271 field-collected M. titillator larvae were analyzed and 26 (9.6 %) tested positive for DNA of members of the SPBG. Of these larvae, 25 (96.2 %) tested positive for I. grandicollis and one (3.8 %) for I. calligraphus. Failure to detect D. terebrans and D. frontalis was likely due to their absence in the field. I. avulsus was present, but primers developed using adult tissues failed to amplify larval tissue. Results from this study support the hypothesis that larval Monochamus spp. are facultative intraguild predators of bark beetle larvae. Additionally, this study demonstrates the capabilities of PCR in elucidating the interactions of cryptic forest insects and provides a tool to better understand mechanisms driving southern pine beetle guild population fluctuations.

    In 2007-2008, we examined the flight responses of wood-boring beetles (Coleoptera: Cerambycidae and Buprestidae) to multiple-funnel traps baited with the pine volatiles, ethanol, and α-pinene [85% (-)], and the bark beetle pheromones, racemic ipsenol and racemic ipsdienol. Experiments were conducted in mature pine stands in Canada (Ontario and New Brunswick) and the United States (Arkansas, Florida, Michigan, New Hampshire, North Carolina, Ohio, Tennessee, and Wisconsin). At each location, traps were deployed in 10 replicate blocks of four traps per block. The trap treatments were: 1) blank control; 2) ipsenol and ipsdienol; 3) ethanol and α-pinene; and 4) a quaternary blend of ipsenol, ipsdienol, ethanol, and α-pinene. Traps baited with the quaternary blend caught the greatest numbers of Acanthocinus nodosus (F.), Acanthocinus obsoletus (Olivier), Acmaeops proteus (Kirby), Astylopsis sexguttata (Say), Rhagium inquisitor (L.) (Cerambycidae), and Buprestis lineata (F.) (Buprestidae). Traps baited with ethanol and α-pinene caught the greatest numbers of Arhopalus rusticus (LeConte), Asemum striatum (L.), Tetropium spp., Xylotrechus sagittatus (Germar) (Cerambycidae), and Buprestis maculipennis Gory (Buprestidae) with minimal interruption by ipsenol and ipsdienol. Our results suggest that multiple-funnel traps baited with the quaternary lure blend of ipsenol, ipsdienol, ethanol, and α-pinene are effective for trapping various species of wood-boring beetles in pine forests of eastern North America, and may have utility in detection programs for adventive species in North America and overseas.

    Abstract Sixteen species of Cerambycidae are newly recorded for New Brunswick, Canada; Arhopalus obsoletus (Randall), Atimia confusa confusa (Say), Callidium frigidum Casey, Phymatodes amoenus (Say), Phymatodes testaceus (Linnaeus), Neoclytus mucronatus mucronatus (Fabricius), Xylotrechus aceris Fisher, Xylotrechus sagittatus sagittatus (Germar), Tylonotus bimaculatus Haldeman, Lepturges angulatus (LeConte), Lepturges symmetricus (Haldeman), Urgleptes querci (Fitch), Oplosia nubila (LeConte), Eupogonius subarmatus (LeConte), Monochamus carolinensis (Olivier), and Pogonocherus parvulus LeConte. Urgleptes signatus (LeConte) and Urgleptes querci are newly recorded from Nova Scotia. All but two specimens were collected in 12-funnel Lindgren traps. Xylotrechus aceris, Tylonotus bimaculatus, Lepturges angulatus, Lepturges symmetricus, Urgleptes signatus (NS), and Pogonocherus parvulus were detected exclusively in traps deployed in the forest canopy, and most individuals of Oplosia nubila and Monochamus carolinensis were captured in canopy traps. Arhopalus obsoletus, Atimia confusa confusa, Callidium frigidum, Phymatodes testaceus, and Xylotrechus sagittatus sagittatus were captured almost exclusively in traps near (1 m above) the forest floor. These results highlight the importance of sampling both the understory and upper canopy when using traps for surveying diversity of Cerambycidae. PMID:26865818

    The chemical structures of aggregation-sex pheromones of longhorned beetles (Coleoptera: Cerambycidae) are often conserved among closely related taxa. In the subfamily Lamiinae, adult males and females of several species are attracted by racemic blends of (E)-6,10-dimethyl-5,9-undecadien-2-ol (termed fuscumol) and the structurally related (E)-6,10-dimethyl-5,9-undecadien-2-yl acetate (fuscumol acetate). Both compounds have a chiral center, so each can exist in two enantiomeric forms. Males of many species of longhorned beetles only produce one stereoisomer of each pheromone component, and attraction may be reduced by the presence of stereoisomers that are not produced by a particular species. In a previous publication, analysis of headspace volatiles of adult beetles of the lamiine species Astyleiopus variegatus (Haldeman) revealed that males sex-specifically produced (S)-fuscumol and (S)-fuscumol acetate. Here, we describe field trials which tested attraction of this species to single enantiomers of fuscumol and fuscumol acetate, or to blends of enantiomers. We confirmed attraction of A. variegatus to its species-specific blend, but during the course of the trials, found that several other species also were attracted. These included Aegomorphus modestus (Gyllenhall), attracted to (S)-fuscumol acetate; Astylidius parvus (LeConte), attracted to (R)-fuscumol; Astylopsis macula (Say), attracted to (S)-fuscumol; and Graphisurus fasciatus (DeGeer), attracted to a blend of (R)-fuscumol and (R)-fuscumol acetate. These results suggest that chirality may be important in the pheromone chemistry of lamiines, and that specific stereoisomers or mixtures of stereoisomers are likely produced by each species.

    The present work analyses the population behavior of Compsocerus violaceus (White, 1853 (Coleoptera, Cerambycidae, related to the fauna of cerambicideos, collected in conserved and rio tangerine, baianinha and natal orange, tangor sabará and cravo lemon. The collections were carried out fortnightly, using a plastic bait trap with 20% molasses. The baits were replaced every two weeks. The collection period ranged from August/1983 to JuIy/1985. The ecological parameters studied included the relative abundance, constancy, frequency and dominance. The influence of some meteorological factors over the species population was also investigated. In the abandoned yard 405 adults were collected, comprising 180 males and 225 females, and in the conserved yard, 253 adults were collected, comprising 96 males and 163 females. From the total insects collected, 39% were from the conserved yard, while 61% came from the abandoned yard. The period showing the highest occurrence was the one comprising the months of November and December, in both yards. No correlation between meteorological factors and species fluctuation could be detected. Among the ecological parameters analyzed, C. violaceus was classified as “common and very abundant”, “accidental and constant”. C. violaceus showed a frequency of 10,31% among the collected species, and was considered “dominant” in both yards, obtaining the classification of Dorcacerus barbatus, Macropophora accentifer, Acathoderes jaspidea, Chlorida festiva and Trachyderes spp., all recognized as dangerous species with a remarkable economic importance for the Brazilian fruit-bearing plants.

    Abstract: Scarabaeoidea superfamily (Insecta: Coleoptera) as a bioindicator element of anthropogenic disturbance in an amazon national park. Insects have been recognized to be important indicators of the quality elements of ecosystems, among others, because of their rapid response to environmental variability and ease cost-effective capture. In this work we evaluated whether beetles of the Scarabaeoidea superfamily may be used as bioindicators of anthropogenic disturbance of Amazonian terra firme rain forests, in order to provide guidelines for monitoring strategies of the Amacayacu National Park. We considered three different levels of anthropogenic disturbance (i.e. low, medium, high) in 12 transects (four in each intervention level), and caught all beetle species of this superfamily. Three interception traps, two light traps, three pitfalls and four bottle fruit traps were used per transect, as well as manual catch. In total, 593 individuals belonging to 92 species, 44 genera and seven families were collected. Scarabaeidae (n = 232, 27 spp.) and Dynastidae (n = 161, 26 spp.) were the families with the highest number of individuals and species, while Aphodiidae, Cetoniidae and Geotrupidae exhibited the lowest. The most abundant species per family were Ateuchus sp. (33.2%) from Scarabaeidae, Cyclocephala verticalis (55.9%) from Dynastidae, Astaena sp. (75.8%) from Melolonthidae, Ceratocanthus amazonicus (66.7%) from Ceratocanthidae y Chaetodus asuai (96.8%) from Hybosoridae. Results showed that the number of species and individuals increased with the anthropogenic disturbance. The Margalef and Shannon indexes also revealed that the highest richness and equity occurred in the high-disturbed site, respectively. Dynastidae exhibited the highest number of exclusive species per gradient, while Scarabaeidae shared most of its species. Ten species were recorded in the three disturbance levels, 26 species in two and 56 species were exclusive to one level. The most

    In 2007-2008, we examined the flight responses of Monochamus titillator (F.) complex [M. titillator, Monochamus carolinensis (Olivier), and any possible hybrids], Monochamus scutellatus (Say), Monochamus clamator (LeConte), Monochamus obtusus Casey, and Monochamus mutator LeConte (Coleoptera: Cerambycidae) to multiple-funnel traps baited with and without host volatiles and bark beetle pheromones. Experiments were conducted in mature pine (Pinus) stands in Alberta (Canada), and Arkansas, Arizona, California, Florida, Idaho, Michigan, Montana, New Hampshire, North Carolina, Ohio, Oregon, Tennessee, Utah, and Wisconsin (United States). At each location, traps were deployed in 10 replicate blocks of four traps per block. The trap treatments were: 1) blank control; 2) ipsenol and ipsdienol; 3) ethanol and alpha-pinene; and 4) a quaternary blend of ipsenol, ipsdienol, ethanol, and alpha-pinene. All five species or species complex of Monochamus preferred traps baited with the quaternary blend over all other treatments. The consistency of these results across such a large geographic area suggests that similar selection pressures may be acting on Monochamus spp. in pine forests, regardless of variation in stand composition and climatic conditions. Our results suggest that multiple-funnel traps baited with the quaternary blend ofipsenol, ipsdienol, ethanol, and alpha-pinene may be highly effective for monitoring various Monochamus spp. in pine forests of North America, and may have utility in trapping and detection programs in North America and overseas.

    Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), an invasive pest quarantined in the United States, is difficult to detect because the larvae feed unseen inside trees. Acoustic technology has potential for reducing costs and hazards of tree inspection, but development of practical methods for acoustic detection requires the solution of technical problems involving transmission of resonant frequencies in wood and high background noise levels in the urban environments where most infestations have occurred. A study was conducted to characterize sounds from larvae of different ages in cambium, sapwood, and heartwood of bolts from three host tree species. Larval sounds in all of the tested trees and tissues consisted primarily of trains of brief, 3-10-ms impulses. There were no major differences in the spectral or temporal pattern characteristics of signals produced by larvae of different ages in each tissue, but larval sounds in sapwood often had fewer spectral peaks than sounds in cambium and heartwood. A large fraction, but not all background sounds could be discriminated from larval sounds by automated spectral analyses. In 3-min recordings from infested bolts, trains containing impulses in patterns called bursts occurred frequently, featuring 7-49 impulses separated by small intervals. Bursts were rarely detected in uninfested bolts. The occurrence of bursts was found to predict infestations more accurately than previously used automated spectral analyses alone. Bursts and other features of sounds that are identifiable by automated techniques may ultimately lead to improved pest detection applications and new insight into pest behavior.

    ( E)-6,10-dimethyl-5,9-undecadien-2-ol (geranyl acetol), termed here fuscol, was identified as a male-produced pheromone emitted by Tetropium fuscum (F.) and Tetropium cinnamopterum Kirby. In field experiments, traps baited with synthetic fuscol alone were not significantly attractive, but the combination of fuscol plus host volatiles (a synthetic blend of monoterpenes plus ethanol) attracted significantly more male and female T. fuscum and female T. cinnamopterum than did host volatiles alone. This is the first homoterpenoid alcohol to be described in the Cerambycidae, and the first pheromone reported from the sub-family Spondylidinae.

    The species richness, abundance and seasonality of Coleoptera fauna associated with pig carcasses exposed in a Caatinga area were examined. Tray, pitfall and modified Shannon traps were settled together to collect these insects during two seasons (dry and rainy). 4,851 beetles were collected, belonging to 19 families and 88 species. Staphylinidae (2,184) and Histeridae (1,264) were the most abundant families and accounted for 71.1% of the specimens collected. Scarabaeidae (15) showed the highest species richness. The most abundant species were Atheta iheringi Bernhauer, 1908 (Staphylinidae) (1,685), Euspilotus sp.

    Full Text Available In order to investigate the affinities of the hitherto considered Neotropical Cleomenini genera, a detailed morphological comparative study was carried out based on representatives of their type species and other congeneric species. The results, when compared with representatives of Cleomenes Thomson and other non Neotropical Cleomenini genera together with representatives of Rhopalophorini Blanchard and Rhinotragini Thomson, show that: 1 Listroptera Audinet-Serville, 1834, Dihammaphora Chevrolat, 1859, Haenkea Tippmann, 1953, Aguassay Napp & Mermudes, 2001 and Timabiara Napp & Mermudes, 2001 form a very homogeneous group, not related to other Cleomenini, but sharing several synapomorphies with the Rhopalophorini; therefore they are herein transferred to this tribe; 2 the affinities of Dihammaphoroides Zajciw, 1967, were not clearly defined, needing further investigations; nevertheless, the genus is tentatively included in Rhopalophorini due to its morphological similarity with Dihammaphora and allied genera; 3 Pandrosos Bates, 1867 is brought back to Rhinotragini, in which it was originally placed. Therefore, the tribe Cleomenini Lacordaire is no longer represented in the New World.Estudo morfológico comparado dos gêneros neotropicais de Cleomenini e sua transferência para as tribos Rhopalophorini Blanchard e Rhinotragini Thomson (Coleoptera, Cerambycidae, Cerambycinae.

    Longhorn wood-boring beetles (Coleoptera: Cerambycidae) use olfactory cues to find mates and hosts for oviposition. Tetropium fuscum (Fabr.) is an invasive longhorned wood-boring beetle originating from Europe that has been established in Nova Scotia, Canada, since at least 1990. This study used single sensillum recordings (SSR) to determine the response of olfactory receptor neurons (ORNs) in the antennal sensilla of male and female T. fuscum to different kinds of olfactory cues, namely host volatiles, non-host volatiles, the aggregation pheromone of T. fuscum (fuscumol), and an aggregation pheromone emitted by other species of longhorn beetles (3-hydroxyhexan-2-one). Each compound had been previously shown to elicit antennal activity in T. fuscum using electroantennography or had been shown to elicit behavioral activity in T. fuscum or other cerambycids. There have been very few SSR studies done on cerambycids, and ours is the first to compare response profiles of pheromone components as well as host and non-host volatiles. Based on SSR studies with other insects, we predicted we would find ORNs that responded to the pheromone alone (pheromone-specialists), as well as ORNs that responded only to host or non-host volatiles, i.e., separation of olfactory cue perception at the ORN level. Also, because male T. fuscum emerge earlier than females and are the pheromone-emitting sex, we predicted that the number of pheromone-sensitive ORNs would be greater in females than males. We found 140 ORNs housed within 97 sensilla that responded to at least one of the 13 compounds. Fuscumol-specific ORNs made up 15% (21/140) of all recordings, but contrary to our prediction, an additional 22 ORNs (16%) responded to fuscumol plus at least one other compound; in total, fuscumol elicited a response from 43/140 (31%) of ORNs with fuscumol-specific ORNs accounting for half of these. Thus, our prediction that pheromone reception would be segregated on specialist ORNs was only partially

    Full Text Available During the 1997–2006 and 2010–2011winter seasons, in the area of Morozova Gora (the nature reserve "Galichya Gora", in Russia, 1200 samples of various substrata were taken, most of which were 4500 cm3 in volume. In total, 41,854 specimens of 690 species belonging to 52 Coleoptera families were registered at overwintering sites. The analysis of the peculiarities of imago Coleoptera groups in the major winter habitats showed that in most of the investigated substrata representatives of the Staphylinidae family prevailed both in terms of species diversity and number. It is only under the bark of trees and in deadwood that Carabidae are the most numerous, whereas Latridiidae are prevalent in tinder fungi. Turf has the maximal species saturation during the winter season (the highest percentage of species referring to 18 families was registered here, as well as plant litter (10 families, with turf being the preference of 8 families richest in species diversity. The imagos of a number of families relatively rich in species – Cantharidae, Malachiidae, Melandryidae, Mordellidae, Oedemeridae, Meloidae, Scraptiidae and Anthribidae – were not found at overwintering sites, which is explained by the preimaginal overwintering of most representatives of the abovementioned families. It was shown that in substrata which are the least suitable for the overwintering of the imago of most Coleoptera species, the highest percentage of the predominant species was registered since more accessible substrata are used as overwintering sites by the same species from different habitats, which decreases the concentration of imago beetles of certain species there. A study of the peculiarities of species distribution (with no less than 30 specimens among overwintering sites showed that the largest number of stenotopic species was registered in droppings (9 species. Then follow the substrata (in decreasing order: turf (5, hay (grass sward, haymow, meadow (4, decomposing

    Full Text Available The pheromones of the weevils has been the most studied and used so far for Coleoptera species. The majority of reported weevil pheromones is produced by males and usually attract both sexes. The identified pheromone compounds are classified in two categories: ten-carbon compounds with terpenoid branching and compounds of various sizes, apparently of fatty-acid origin. These pheromone structural categories are consistent within subfamilies. This review aims to give an overview of the aggregation pheromones identified for Curculionidae pests, describing the relationship of the molecules structural pattern among subfamilies, and propose an identification key based on the structure of the pheromone components.

    Abstract. The palm trees correspond to an important element in tropical ecosystems, serving as food source and habitat for a wide variety of invertebrates and vertebrates. Considering the role of these plants as hosts of different species, this study evaluated descriptively the composition, trophic guilds and biomass of the community of Coleoptera associated with canopies Attalea phalerata Mart. (Arecaceae in the Pantanal of Poconé, Mato Grosso. Six palm trees were sampled during the high water season of the Pantanal of Mato Grosso (February 2001, by canopy fogging. A total of 7,670 specimens were collected (77.5 ind./m², 5,044 adults (65.7%; 50.9 ind./m² and 2,626 larvae (34.3%; 26.5 ind./m². Adults (65.7% represented 43 families and 467 morphospecies. The dominant families were Endomychidae, Nitidulidae, Tenebrionidae, Staphylinidae and Curculionidae, representing 66.9% of the total catch. Saprophages, fungivores and herbivores prevailed over predators. Highest richness of species was found for Staphylinidae, Curculionidae, Tenebrionidae and Chrysomelidae. Highest biomass was found in Scarabaeidae and Tenebrionidae followed by Nitidulidae and Curculionidae. These results indicate that the canopy of A. phalerata is habitat for a wide variety of Coleoptera, as well a reproduction site, as evidenced by the high number of larvae sampled in this study.

    Weevils (Coleoptera: Curculionidae) are identified by the external structure (dorsal, ventral and lateral features) and also by internal structure. The genitalia can be used to distinguish the sex and to identify the insects when the external structure appears identical. For this purpose, a destructive dissecting microscopy procedure is usually employed. In this paper, phase contrast X-ray imaging (radiography and tomography) is employed to investigate the internal structure (genitalia) of two entire species of weevils that presents very similar external structures (Sitophilus oryzae and Sitophilus zeamais). The detection of features, which looks like the genital structure, shows that such non-destructive technique could be used as an alternative method for identification of insects. This method is especially useful in examining the internal features of precious species from museum collections, as already described in the recent literature.

    The phylogeny and related evolutionary history of rove beetles (Coleoptera, Staphylinidae) remain unclear. This study provides phylogenetic analyses for the family based on three genes (mitochondrial COI, nuclear protein-coding wingless and a portion of the ribosomal 28S rDNA) including 2413 bp for 104 taxa representing most major staphylinid lineages. The subfamilies Oxyporinae, Paederinae, Steninae, and Proteininae are all well-supported clades, as evidenced by all three inference methods, namely maximum parsimony, Bayesian inference, and maximum likelihood. From fossils available for calibration, the divergence time of the main lineages in the family is estimated based on an uncorrelated lognormal relaxed molecular clock analysis method. The molecular clock analysis suggests that the family Staphylinidae dates from approximately the Early Triassic epoch and the most lineages of the family started to radiate from the Late Jurassic to the Early Paleogene.

    Abstract. Insecta is the most diverse, abundant and dominant group of arthropods, being used in diversity studies as biological indicators. Despite this, there are few studies regard to coleopterofauna and its relation to coastal environments. Salt marshes and sandbanks are characterized by their ecological importance of coastal regions of the southwest Atlantic. Therefore, this study aimed to compare the fauna of Coleoptera captured in a sandbank area with the fauna of a salt marsh in the estuary of the lagoon Lagoa dos Patos, RS. Samples were collected from August 2007 to July 2008 in sandbank area; and from September 2008 to August 2009 in the salt marsh area. A total of 826 beetles were collected, distributed in 26 families. The results suggest that both sandbank and salt marsh presented equally rich families, but with alternation of dominance between the areas. Coleoptera communities flutuactions in each area were different in the period; however, the peak abundance of both areas coincided with the warmer months. The diversity of families was higher in the area of sandbank, while families caught in sandbanks have greater similarity to those found in both areas. Groups classified as rare surpassed common. Families of varied habit appeared in both environments; nonetheless, the herbivorous dominated in the sandbank and carnivorous in the salt marsh.

    Full Text Available Coleoptera is a group of insects that are most diverse among insect resources. Although used as indicator species and applied in developing new drugs, it is difficult to identify them quickly. Since the development of a method using mitochondrial DNA information for identification, studies have been conducted in Korea to swiftly and accurately identify species. The National Science Museum of Korea (NSMK has been collecting and morphologically identifying domestic reference insects since 2013, and building a database of DNA barcodes with digital images. The NSMK completed construction of a database of digital images and DNA barcodes of 60 beetle species in the Korean National Research Information System. A total of 179 specimens and 60 species were used for the analysis, and the averages of intraspecific and interspecific variations were 0.70±0.45% and 26.34±6.01%, respectively, with variation rates ranging from 0% to 1.45% and 9.83% to 56.23%, respectively.

    In North America, cerambycid beetles can have significant ecological and economic effects on forest ecosystems, and the rate of introduction and/or detection of exotic species is increasing. Detection and survey programs rely on semiochemical-baited intercept traps which are often ineffective for large woodborers like cerambycid beetles. This study examined the effects of flight intercept trap design on the capture of cerambycid beetles in the subfamilies Lamiinae and Cerambycinae. These subfamilies are the two largest in the Cerambycidae and they include many of the most damaging cerambycid pests and species on regulatory watch lists in North America. This study demonstrates that intercept trap design, treatment of trap surfaces with a lubricant, and the type of collection cup all influence the capture of beetles from the subfamilies Lamiinae and Cerambycinae. It also demonstrates that the addition of a large lubricant-treated collar to the bottom funnel of a multiple-funnel trap significantly increases the capture of some Lamiinae. The best trap design for both subfamilies was a lubricant treated multiple-funnel [MF] trap equipped with a wet cup and lubricant treated large collar on the bottom funnel. This design captured between 4 and 14 times more Lamiinae and Cerambycinae than commercially-available MF and panel traps.

    Full Text Available Várias questões sobre a biodiversidade vêm sendo levantadas nas últimas décadas. Uma delas é o papel que as plantações florestais exóticas monoculturais desempenham na manutenção da fauna nativa, principalmente de insetos. Estudos têm demonstrado que os Coleoptera são sensíveis a variações florísticas e estruturais, em pequena escala espacial. Para analisar as possíveis diferenças na diversidade de Coleoptera entre um ambiente de floresta natural e uma plantação florestal exótica monocultural foi desenvolvido um inventário no Parque Ecológico Vivat Floresta, Tijucas do Sul, Paraná. Para tanto, durante 52 semanas (agosto de 2004 a julho de 2005, seis armadilhas malaise foram dispostas ao longo de um transecto através de dois ambientes adjacentes, com diferentes condições florísticas: três em fragmento da floresta natural (Floresta Ombrófila Mista e três na plantação de Pinus elliottii exótico. Neste primeiro estudo, as comunidades de Coleoptera foram analisadas com base na abundância e na riqueza das famílias. Foram coletados 12397 exemplares de 57 famílias. A abundância foi maior na floresta natural, decrescendo do interior desta para o interior da plantação de pinus. O ecótono - borda da floresta natural/borda da plantação de pinus - foi o mais rico em famílias. Como observado em inventários de outras localidades, os estudos apoiados em dados das famílias que se incluem nos primeiros 60% da abundância total de cada área, mostram os mesmos resultados quando são aplicados os dados de todas as famílias. Na plantação de pinus as famílias dominantes foram, pela ordem: Cerambycidae, Staphylinidae, Curculionidae, Nitidulidae, Lampyridae, Scolytidae, Chrysomelidae; na floresta natural: Chrysomelidae, Cerambycidae, Curculionidae, Lampyridae, Nitidulidae, Staphylinidae.An important question for biodiversity is what is the impact of monocultures of exotic forest trees on native fauna, especially

    Here, we report the mitochondrial genome sequence of the multicolored Asian lady beetle Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) (GenBank accession No. KR108208). This is the first species with sequenced mitochondrial genome from the genus Harmonia. The current length with partitial A + T-rich region of this mitochondrial genome is 16,387 bp. All the typical genes were sequenced except the trnI and trnQ. As in most other sequenced mitochondrial genomes of Coleoptera, there is no re-arrangement in the sequenced region compared with the pupative ancestral arrangement of insects. All protein-coding genes start with ATN codons. Five, five and three protein-coding genes stop with termination codon TAA, TA and T, respectively. Phylogenetic analysis using Bayesian method based on the first and second codon positions of the protein-coding genes supported that the Scirtidae is a basal lineage of Polyphaga. The Harmonia and the Coccinella form a sister lineage. The monophyly of Staphyliniformia, Scarabaeiformia and Cucujiformia was supported. The Buprestidae was found to be a sister group to the Bostrichiformia.

  3. Bioindication Potential of the Coleoptera

    Full Text Available Different families of Coleoptera ambiguously respond to the pollution of SPZs with industrial emissions. For example, the SPZ of Volgograd aluminum plant has the changing biodiversity of insect communities at different distances from the pollution source. The increasing level of pollution is accompanied by the reduction in species abundance. At a distance of 200 m a special ecological zone with the specific composition of the entomofauna was formed. It is significantly different from other habitats. No Cerambycidae species may survive in the zone of maximum pollution, and the number of Curculionidae species is reduced significantly. The number of Cerambycidae decreases by more than 40 % in the presence of even minimal contamination. The most sensitive bioindicators are represented by such insects as Cerambycidae, Curculionidae and Chrysomelidae. Changes in the indices can be described by the function y = arctan (x, where x is the distance from the pollution source (in meters. The specificity of this function is to identify levels of possible changes of species richness and numerical abundance of communities. On the basis of trigonometric functions describing the changes in the species composition and abundance, the authors offered the method for assessing the quality of the environment in SPZs. The use of three families of insects opens up prospects of differentiation zones of technogenic pressure.

    Coleoptera is the largest and diverse group of organisms, but few studies are dedicated to determine the diversity and feeding guilds of saproxylic Coleoptera. We demonstrate the diversity, abundance, feeding guilds, and succession process of Coleoptera associated with decaying wood in a tropical deciduous forest in the Mixteca Poblana, Mexico. Decaying wood was sampled and classified into four stages of decay, and the associated Coleoptera. The wood was identified according to their anatomy. Diversity was estimated using the Simpson index, while abundance was estimated using a Kruskal-Wallis test; the association of Coleoptera with wood species and decay was assessed using canonical correspondence analysis. Decay wood stage I is the most abundant (51%), followed by stage III (21%). We collected 93 Coleoptera belonging to 14 families, 41 genera, and 44 species. The family Cerambycidae was the most abundant, with 29% of individuals, followed by Tenebrionidae with 27% and Carabidae with 13%. We recognized six feeding guilds. The greatest diversity of Coleoptera was recorded in decaying Acacia farnesiana and Bursera linanoe. Kruskal-Wallis analysis indicated that the abundance of Coleoptera varied according to the species and stage of decay of the wood. The canonical analysis showed that the species and stage of decay of wood determined the composition and community structure of Coleoptera.

    In order to explore the role of the visual factors, for Monochamus alternatus (Coleoptera: Ceramby cidae) four treatments of field traps (black, brown, green, and gray-control) were tested. The mating behavior was observed after M. alternatus' visual organ compound eyes and olfaction were treated. Results showed that the black and brown traps were stronger than the gray (control) traps (P<0.05); but the green traps were weaker than the control (P<0.05=. In mating behavior assays, after the compound eyes were treated, the percentage of mating success decreased to 50.7% compared to the control which had an average of 93.3%. Also, the proportion of mating success after treating olfaction (antenna were cutting down) averaged 72.3%, which was lower than the control (P<0.05=. With both vision and olfaction treated, the proportion of mating success averaged 26.7%, also lower than the control (P<0.05). This indicated that visual cues over short distances were very important in the mating behavior of M. alternatus.

    Full Text Available Il presente lavoro fornisce un primo contributo alla conoscenza della biologia di Vesperus macropterus Sama, 1999 ed è basato su osservazioni in campo, effettuate in un sito della provincia di Cagliari. Le femmine di questa specie depongono le uova sulle infiorescenze disseccate di alcune piante erbacee anche a più di 1,5 m di altezza; le larve neonate raggiungono il terreno spostandosi sulla superficie o all’interno della pianta, a seconda della specie vegetale dove è avvenuta la deposizione. In nessuna altra specie del genere Vesperus Dejean, 1821 è mai stata osservata una tale biologia. Si ipotizza inoltre che esista una correlazione tra lo sviluppo delle ali membranose delle femmine e l’atipica strategia di ovideposizione della specie.

    Full Text Available The LIFE project “MIPP” - Monitoring of Insects with Public Participation (11 NAT/IT/000252 is focused on selected insect species (five Coleoptera, three Lepidoptera, one Orthoptera, all included in the annexes II and IV of the Habitats Directive (HD 92/43/EEC. One important aim is a citizen science initiative where every person may become a citizen scientist and collect faunistic data on the above species throughout Italy. Another objective of the project MIPP is the development of standard methods for monitoring the conserva- tion status of the five target beetle species. One innovative method employed is a sniffer-dog (“Osmodog”, trained to find the rare and endangered hermit beetle, Osmoderma eremita, which lives in veteran, hollow trees. The dog detects the strong smell of mature peach produced by adult males and an odor produced by the larvae. Another objective of the project MIPP is the dissemination of topics such as HD, Natura 2000, importance of dead-wood, Life projects, insect monitoring and conservation.

    Full Text Available Se describen y comparan los ensamblajes de coleópteros de las temporadas de lluvias y sequía del bosque mesófilo de montaña de Tlanchinol, Hidalgo, que se obtuvieron en 8 recolectas mensuales usando trampas de intercepción de vuelo. Para la descripción de los ensamblajes se tomó en cuenta su riqueza, composición, diversidad, equidad y dominancia y se compararon con base en los perfiles de diversidad de Renyi. El recambio de especies se evaluó usando el índice de similitud de Bray-Curtis. Se estimó la riqueza teórica del ensamblaje total y por temporada, se exploró la relación entre los taxa y los meses de recolecta, y las especies se ubicaron en grupos funcionales. Los 3 308 ejemplares recolectados pertenecen a 50 familias y 352 especies, siendo Staphylinidae, Curculionidae y Nitidulidae las familias con el mayor número de especies. La riqueza, abundancia y diversidad de la época de sequía fueron significativamente mayores que las de lluvias. La mayoría de las especies poseen abundancias inferiores a 1% conformando las especies raras. Teóricamente aún faltan taxa por recolectarse en Tlanchinol. La mayoría de las especies se ubicaron en la categoría de los depredadores (43% y fitófagos (20%. Los resultados resaltan la gran biodiversidad de estos bosques y su urgente necesidad de protección.We described and compared Coleoptera assemblages in rainy and dry seasons in the cloud forest in Tlanchinol, Hidalgo, Mexico, based on 8 monthly samples using flight interception traps. Assemblages were described using richness and composition as well as some diversity measurements; we then used Renyi's diversity profiles to compare them. A Bray-Curtis similarity index was used to evaluate species turnover rate between seasons. The theoretical richness by parametric methods was estimated, the relationship between species and the collecting months were analyzed with a correspondence analysis, and species were placed into functional groups

    Full Text Available Besouros pertencentes à superfamília Scarabaeoidea ocupam habitats variados, possuem hábitos alimentares diversificados, desempenham importante papel ecológico e diversas espécies apresentam importância agrícola. No entanto, estudos com esse grupo na região do Cerrado são escassos. Nesta revisão realizou-se um levantamento dos artigos publicados nos últimos 30 anos a respeito dos Scarabaeoidea no Cerrado. Foram recuperados 64 artigos, realizados em nove unidades da federação, que focavam quatro temas principais: espécies praga, aspectos bioecológicos, biodiversidade e importância ecológica, e técnicas e metodologias de coleta de Scarabaeoidea. Os resultados desta revisão indicam que poucos estudos foram realizados com os Scarabaeoidea no Cerrado brasileiro nas últimas décadas frente à importância e diversidade desse grupo de insetos.

Observations were conducted in a homogeneous eight years-old erva-mate population under 1.5 m x 2.0 m spacing layout in 15 ha and 20 ha fields in both Ilópolis, State of Rio Grande do Sul and Catanduvas, State of Santa Catarina, respectively. The observations were conducted hourly during six days, totalizing 144 observations in Ilópolis (RS and three days, totalizing 72 observations in Catanduvas (SC, February and March, 2001, respectively. The environmental factors temperature (°C, relative humidity (%, wind speed (m/s and light intensity (Klux were evaluated using a thermohygrograph, an anemometer and a luximeter. The behavioral aspects observed were mating, oviposition, feeding, male keeping female, standing alone insect and insect in movement. Oviposition and feeding were the only behaviors affected by the periods of the day and environmental conditions. Considering other behaviors, Hedypathes betulinus presents no preference in relation to the periods or hours of the day they occur.

    Phoracantha longicorn beetles are endemic to Australia, and some species have become significant pests of eucalypts worldwide, yet little is known about their host plant interactions and factors influencing tree susceptibility in Australia. Here, we investigate the host relationships of Phoracantha solida (Blackburn, 1894) on four eucalypt taxa (one pure species and three hybrid families), examining feeding site physical characteristics including phloem thickness, density, and moisture content, and host tree factors such as diameter, height, growth, taper, and survival. We also determine the cardinal and vertical (within-tree) and horizontal (between-tree) spatial distribution of borers. Fewer than 10% of P. solida attacks were recorded from the pure species (Corymbia citriodora subsp. variegate (Hook)), and this taxon also showed the highest survival, phloem thickness, relative growth rate, and bark:wood area. For the two most susceptible taxa, borer severity was negatively correlated with moisture content, and positively related to phloem density. Borers were nonrandomly and nonuniformly distributed within trees, and were statistically aggregated in 32% of plots. More attacks were situated on the northern side of the tree than the other aspects, and most larvae fed within the lower 50 cm of the bole, with attack height positively correlated with severity. Trees with borers had more dead neighbors, and more bored neighbors, than trees without borers, while within plots, borer incidence and severity were positively correlated. Because the more susceptible taxa overlapped with less susceptible taxa for several physical tree factors, the role of primary and secondary chemistries in determining host suitability needs to be investigated. Nevertheless, taxon, moisture content, phloem density, tree size, and mortality of neighboring trees appeared the most important physical characteristics influencing host suitability for P. solida at this site.

  19. Influence of nutrient substrates on the expression of cellulases in Cerambyx cerdo L. (Coleoptera: Cerambycidae larvae

    2012-01-01

    Full Text Available The expression and distribution of digestive cellulases along the midgut of Cerambyx cerdo larvae were analyzed for the first time and are presented in this article. Four groups of larvae were examined: larvae developed in the wild; larvae taken from the wild and successively reared on an artificial diet based on polenta; and larvae hatched in the laboratory and reared on two different artificial diets. Seven endocellulase and seven β-D-glucosidase isoforms were detected in all midgut extracts of C. cerdo with a zymogram after native PAGE. We observed that C. cerdo larvae are capable of producing cellulase isoforms with different PAGE mobilities depending on the nutrient substrate. From our findings it can be assumed that, depending on the distribution of endocellulase and β-D-glucosidase, cellulose molecules are first fragmented in the anterior and middle midgut by endo-β-1,4-glucanase; subsequently, the obtained fragments are broken down by β-D-glucosidase mostly in middle midgut.

  20. [Longicorn beetles (Coleoptera:Cerambycidae) differ considerably in the degree of their mushroom body development].

    A duality in the general structure of the mushroom body in longicorn beetles is confirmed. This duality is associated with the fact that they are formed by two solitary neuroblasts or two neuroblast clusters on each side of the brain and are manifested as a bipartite structure of both the calyx, which is the main sensory input, and the peduncular apparatus. Within the studied longicorn beetles, modifications in the general structure of mushroom bodies have been found; these modifications are caused by two oppositely directed morphogenetic processes, namely, the concentration of structures and their compartmentalization. The concentration leads to disappearance of the bipartite structure of the peduncular apparatus, whereas compartmentalization leads to a secondary subdivision of these structures into anatomically distinct subsections. This process is most pronounced in the peduncle and lobes. The mushroom bodies are best developed and differentiated in the members of the subfamily Lamiinae.

  5. Cold tolerance and cold hardening strategy of the Japanese pine sawyer Monochamus alternatus (Coleoptera: Cerambycidae)

    The Japanese pine sawyer, Monochamus alternatus, is an important pine forest pest and vector transmitting the pine wilt nematode that causes pine wilt disease. Low temperatures in autumn, winter and spring often differentially affect mortality of M.alternatus larvae. In this paper, we mainly compared the differences of mortality and cold hardening of larvae from different seasons, based on supercooling point (SCP) and cumulative probability of individuals freezing (CPIF). The cold hardening of the larvae from autumn, winter and spring seasons were largely different. Correlations between mortality and CPIF of autumn and spring larvae were highest on day 1/4, and gradually decreased with prolonged exposure duration. This beetle's death mainly resulted from freezing in short exposure duration. However, the correlation between mortality and CPIF of winter larvae increased gradually with the prolonged exposure duration. Death did not mainly result from freezing in long exposure duration. Autumn larvae are more susceptible and adaptable than winter and spring larvae. Winter larvae have a slight freeze-tolerance trend. Our research showed that M. alternatus came into complex cold-hardening strategies under natural selection. Freeze avoidance is the primary strategy; with prolonged exposure duration to above SCP or < 0℃, chill tolerance is more important; this is followed by freeze tolerance during harsh winters.

    Volatiles from female Asian longhorned beetle (ALB),Anoplophora glabripenhis,were evaluated as candidate sex pheromone components.Previous studies on ALB have revealed several antennally active compounds from virgin females; however the origins and activity of these compounds were not apparent and require further investigation.We tested the hypothesis that one or more of the ALB contact sex pheromones is a precursor that undergoes abiotic oxidation to yield volatile pheromone components,and evaluated the activity of these compounds using laboratory and field bioassays.Gas chromatography coupled electroantennography detection (GC-EAD) analysis indicated the presence of three antennally active aldehydes (heptanal,nonanal,and hexadecanal) in female cuticular extracts exposed to ozone or UV and visible light.In laboratory bioassays using a Y-tube olfactometer,males were preferentially attracted to ozonized female body washes over crude body washes.Similarly,synthetic formulations of these compounds were preferred over controls in the olfactometer.Field trapping experiments conducted from 2006 to 2008 in Ningxia,China showed that synthetic lures of the three aldehydes formulated in a ratio simulating that of virgin females attracted more beetles compared to controls,and that combinations of these aldehydes,linalool oxide,and host kairomones captured more beetles than controls,and captured significantly more males.

    Full Text Available The objective of this study was to collect, identify and carry out a faunistic characterization of Cerambycidae occurring in a forest of Eucalyptus spp., on São Manoel farm, in the municipality of Pinheiro Machado, RS. In the period from February 2006 to October 2007, collections of insects were performed every 15 days, with three ethanol traps. After selection procedures, the Cerambycidae were identified based on entomological collections and specialized literature. We collected 692 insects, distributed among 29 genera and 40 species. The most abundant species were Acanthoderes jaspidea, Chlorida costata, Compsocerus barbicornis, Eburodacrys sp., Eurysthea hirta, Neoclytus curvatus and Nyssodrysina lignaria, which represented 81.17% of the total individuals. Cerambycidae were collected during practically the entire sampling period, but the largest number at a single collection occurred in the month of December. Several species demonstrate potential for damaging Eucalyptus spp., of which Neoclytus curvatus deserves the most attention, because it represented almost half of the insects collected.

    The twig girdler beetles are known for damaging many tree species. These beetles girdle branches and use them to lay their eggs and complete the offspring development. The objective of this work was to describe the occurrence of a case of O. dejeanii girdling Pyrus pyrifolia (pear tree branches. Three girdled branches of P. pyrifolia were collected and on two of these were captured a female of this twig-girdler beetle on each. The diameter and average length of the branches were 3.47±0.15 cm and 3.31±0.17 m, respectively. The lower third of the girdled branch has presented 52% of the posture incisions. A female was observed performing two postures along the branch, which took 10 and 13 minutes. O. dejeanii uses P. pyrifolia as alternative host, with potential to become pest and reduce output.

    Full Text Available When symbioses between insects and bacteria are discussed, the origin of a given association is regularly of interest. We examined the evolution of the symbiosis between reed beetles (Coleoptera, Chrysomelidae, Donaciinae and intracellular symbionts belonging to the Enterobacteriaceae. We analyzed the partial sequence of the 16S rRNA to assess the phylogenetic relationships with bacteria we found in other beetle groups (Cerambycidae, Anobiidae, other Chrysomelidae. We discuss the ecology of each association in the context of the phylogenetic analysis. The bacteria in Sagra femorata (Chrysomelidae, Sagrinae are very closely related to those in the Donaciinae and are located in similar mycetomes. The Sagrinae build a cocoon for pupation like the Donaciinae, in which the bacteria produce the material required for the cocoon. These aspects support the close relationship between Sagrinae and Donaciinae derived in earlier studies and make a common ancestry of the symbioses likely. Using PCR primers specific for fungi, we found Candida sp. in the mycetomes of a cerambycid beetle along with the bacteria.

    The antimicrobial properties of the pygidial gland secretions released by the adults of the three ground beetle species, Carabus ullrichii, C. coriaceus, and Abax parallelepipedus, have been tested. Microdilution method was applied for detection of minimal inhibitory concentrations (MICs), minimal bactericidal concentrations (MBCs), and minimal fungicidal concentrations (MFCs). Additionally, morpho-histology of the pygidial glands is investigated. We have tested 16 laboratory and clinical strains of human pathogens—eight bacterial both gram-positive and gram-negative species and eight fungal species. The pygidial secretion samples of C. ullrichii have showed the strongest antimicrobial effect against all strains of treated bacteria and fungi. Staphylococcus aureus, Lysteria monocytogenes, and Salmonella typhimurium proved to be the most sensitive bacterial strains. Penicillium funiculosum proved to be the most sensitive micromycete, while P. ochrochloron and P. verrucosum var . cyclopium the most resistant micromycetes. The pygidial secretion of C. coriaceus has showed antibacterial potential solely against Pseudomonas aeruginosa and antifungal activity against Aspergillus fumigatus, A. versicolor, A. ochraceus, and P. ochrochloron. Antibacterial properties of pygidial gland secretion of A. parallelepipedus were achieved against P. aeruginosa, while antifungal activity was detected against five of the eight tested micromycetes (A. fumigatus, A. versicolor, A. ochraceus, Trichoderma viride, and P. verrucosum var . cyclopium). Commercial antibiotics Streptomycin and Ampicillin and mycotics Ketoconazole and Bifonazole, applied as the positive controls, showed higher antibacterial/antifungal properties for all bacterial and fungal strains. The results of this observation might have a significant impact on the environmental aspects and possible medical purpose in the future.

    2013-01-01

    Mushroom bodies in beetles of the families Histeridae, Staphylinidae, Cantharidae, Trogossitidae, Peltidae, Cleridae, Malachiidae, and Coccinellidae are shown to be rather poorly developed. The calyx region of the mushroom bodies in these beetles never forms two separate cups, and the peduncular apparatus includes a unified shaft almost over its entire length. Only the pedunculus contains two separate shafts in a few cases. Two proliferative centers consisting of one to three neuroblasts are often found in each Kenyon cell group. The shift from carnivorous to feeding on pollen or leaves, which has taken place in some taxa, does not visibly affect the degree of mushroom body development.

    Full Text Available The intense study of coleopteran inclusions from Spanish (Albian in age and French (Albian–Santonian in age Cretaceous ambers, both of Laurasian origin, has revealed that the majority of samples belong to the Polyphaga suborder and, in contrast to the case of the compression fossils, only one family of Archostemata, one of Adephaga, and no Myxophaga suborders are represented. A total of 30 families from Spain and 16 families from France have been identified (with almost twice bioinclusions identified in Spain than in France; 13 of these families have their most ancient representatives within these ambers. A similar study had previously only been performed on Lebanese ambers (Barremian in age and Gondwanan in origin, recording 36 coleopteran families. Few lists of taxa were available for Myanmar (Burmese amber (early Cenomanian in age and Laurasian in origin. Coleopteran families found in Cretaceous ambers share with their modern relatives mainly saproxylic and detritivorous habits in the larval or adult stages, rather than wood-boring behavior. Fifteen of the coleopteran families occur in both the Lebanese and Spanish ambers; while only five are present in both Spanish and French. Considering the paleogeographic proximity and similarity of age of the Spanish and French ambers, the small number of taxa found in common at both areas is surprising. The ancient origin for the Lebanese and Spanish ambers, the paleogeography (including some barriers for terrestrial biota and the local paleohabitats are factors that may explain the dissimilarity with the French specimens. Wildfires are believed to be a more likely cause of resin production during the Cretaceous than infestation by beetles. Current knowledge of the beetle species found in the Cretaceous ambers is introduced.

    Here we examine assemblage structure of coprophagous Scarabaeidae (dung beetles) in the Pantanal of the state of Mato Grosso with respect to flooding regimes, soil texture, leaf litter volume and tree dominance in native and exotic pastures. Samples were collected along 30 transects of 250 m in length in a 5×5 km grid (25 km2). Five pitfalls baited with human feces were placed in each transect. A total of 1692 individuals in 19 species were captured, the majority in the subfamily Scarabaeinae and Aphodiinae. Assemblages were influenced by the duration of flooding and leaf litter volume. None of the other habitat variables was correlated with species richness. Cultivated pastures with exotic grasses were unimportant for composition of the assemblages of beetles. These results indicate that duration of flooding is the most important regulating force in this community.

    2012-06-01

    Mites of the family Klinckowstroemiidae establish an association with beetles of the family Passalidae known as phoresy. In order to obtain information about this association, we analyzed the relationship between mites of the family Klinckowstroemiidae and beetles of the family Passalidae, as adult mites have been exclusively collected from host beetles. We examined 1 150 beetles collected in seven states of the Mexican Republic, and found 19 species of klinckowstroemiid mites associated with 168 passalids, that belong to 28 different species in 15 genera. Host specificity between species of both groups does not exist, as one species of passalid beetle can have several different symbionts; conversely, a given mite species can associate with passalid beetles of different species and even of different genera. This way, Odontotaenius zodiacus has been found associated with mites of seven species of the genus Klinckowstroemia. Besides, Klinckowstroemia valdezi is associated with five species of passalids. Furthermore, two and even three different species of mites have been found on one host beetle (synhospitality). The lack of congruence between the phylogenies of the mites and that of the beetles indicates that a process of co-adaptation by colonization is going on, because the association is due to the resources that passalid beetles can offer to the mites, like transportation, food and refuge. Since these resources are not host-specific, the klinckowstroemiid mites can climb onto virtually any species of passalid beetles occurring on the same habitat.

  20. The history of endemic Iberian ground beetle description (Insecta, Coleoptera, Carabidae): which species were described first?

    Jiménez-Valverde, Alberto; Ortuño, Vicente M.

    2007-01-01

    iological correlates of species description dates can be used to predict the characteristics of yet-to-be-described species. Such information can be useful in the planning of biodiversity field surveys. This paper explores the influence of five factors—body size, geographic range size, geographic location, habitat and number of congeners—on the probability of description of endemic Iberian ground-beetles, and attempts to identify the effects of each factor, alone or in combination, through variation partitioning. Small-bodied and hypogean species were found to have been described later, as were those with smaller geographic ranges, while the number of congeners did not significantly affect description date. Additionally, Eastern hypogean species were described earlier than Western ones because of major lithology differences from east to west in the Iberian Peninsula, and concomitant geographic taxonomic bias. However, effects of each factor alone are quite small in comparison with effects of the combination of factors, due to their considerable correlation. Thus, "rarity", in its broadest sense, has been the determining factor of date of description of endemic Iberian ground-beetles. Previously, the technical difficulty encountered in the study of rare species retarded their description, whereas now they have become a "fashionable" object of study among carabidologists, due to the possibility of rapid publication. In order to improve the incomplete checklist of Iberian ground beetles it would be necessary to focus sampling efforts on marginal habitats and hypogean fauna.

    2013-01-01

    Contrary to members of the suborder Polyphaga; ground beetles have been found to possess tripartite mushroom bodies, which are poorly developed in members of basal taxa and maximally elaborated in evolutionarily advanced groups. Nevertheless, they do not reach the developmental stage, which has been previously found in particular families of beetles. It has been pointed out that anew formation of the Kenyon cells occurs during at least the first months of adult life, and inactive neuroblasts are found even in one-year-old beetles. It has been suggested that there is a relation between the Kenyon cell number and development of the centers of Kenyon cell new-formation.

    Full Text Available ResumoNos insetos, o corpo gorduroso pode ser considerado um centro de metabolismo intermediário e também o local de síntese de alguns componentes da hemolinfa. Com objetivo de obter maiores informações sobre essa estrutura, foi realizado um estudo para a sua caracterização morfológica em adultos de Hedypathes betulinus Klug. Os resultados mostram que a estrutura ocorre em duas porções, a primeira, aderida ao trato digestivo e a segunda, associada ao tegumento, denominando-se, corpo gorduroso perivisceral e parietal, respectivamente. Histologicamente o corpo gorduroso apresenta dois tipos celulares, os trofócitos e os enócitos. Os trofócitos apresentam na área citoplasmática, vacúolos, núcleos esféricos, cromatina granular com variações na condensação, e em alguns casos, foram observados núcleos deslocados para a periferia celular. A presença de nucléolos múltiplos em algumas células sugere alta atividade nuclear. Os enócitos foram observados associados aos trofócitos, com núcleos centrais de formato esférico e cromatina de aspecto granular dispersa; os nucléolos apresentaram-se proeminentes em número variável e diferem dos trofócitos pela ausência de vacúolos, citoplasma granular, formato e tamanho das células.AbstractIn insects, the fat body may be considered a center of intermediary metabolism and also the site of synthesis of some components of the hemolymph. Aiming to obtain more knowledge about this structure, a study for characterization of morphological Hedypathes betulinus Klug was carried out. The results show that it takes place in two parts: the first one is adhered to the digestive tract, and the second one, associated with the coat, called the fat body and parietal perivisceral, respectively. Histologically the fat body is composed of two cell types, the trophocytes and the oenocites. The trophocytes present, in its cytoplasmic, vacuoles, spherical nuclei, granular chromatin with variations in condensation, and in some cases, it was observed nuclei displaced to periphery cells. The presence of multiple nucleoli in some cells suggests high nuclear activity. The oenocites were observed associated with trophocytes with central nuclei of spherical shape and granular appearance, dispersed chromatin, the nucleoli were prominent in variable number and differ from trophocytes by the absence of vacuoles, cytoplasm granular, shape and size of cells.

    Full Text Available Yerba mate is an important crop of southern Brazil, Argentina and Paraguay, with socio-economic and environmental importance. Due the lack of native herbals, yerba mate has become a monoculture, and as a consequence, insects have become pests, and the borer, Hedypathes betulinus, one of the most important. In order to improve biological control in the crop, this work aims to select in laboratory the most virulent, of 32 isolates of the entomopathogenic fungi Beauveria bassiana (Bals. Vuill. and 18 isolates of Metarhizium anisopliae (Metsch. Sorok. Initially, isolates virolence was evaluated by immersing the adults borers in a fungal suspension, containing 1×108 conidia mL-1, and after, those caused highest confirmed mortality were selected for the second step, wherein it was evaluated the virulence, vegetative growth and conidia production in culture medium, rice and borer bodies. Three isolates of B. bassiana (UNIOESTE 4, UNIOESTE 52 and UNIOESTE 64 and one of M. anisopliae (IBCB 352 reached confirmed mortality equal or superior to 90%, these isolates were selected for the second step, together with the standard isolated GC 716 (B. bassiana. The isolated IBCB 352 of M. anisopliae, despite being the only of this species to be selected for the second step, promoted the high confirmed mortality and conidiogenesis in adults borer, indicating a high inoculums production i, being nominated for field evaluations. A erva-mate é uma cultura importante da região sul do Brasil, Argentina e Paraguai, tendo grande importância sócio-econômica e ambiental. Com a escassez de ervais nativos, a cultura da erva-mate passou a ser cultivada em sistema de monocultivo e como consequência, alguns insetos tornaram-se pragas, sendo a broca, Hedypathes betulinus, muito importante. A fim de incrementar o controle biológico na cultura, o objetivo deste trabalho foi selecionar em laboratório os isolados mais virulentos de 32 isolados do fungo entomopatogênico Beauveria bassiana (Bals. Vuill. e 18 isolados de Metarhizium anisopliae (Metsch. Sorok.. Inicialmente, avaliou-se a virulência dos isolados imergindo adultos da broca da erva-mate em suspensão fungica contendo 1×108 conídios mL-1, e posteriormente os que obtiveram maior mortalidade confirmada, foram selecionados para segunda etapa, na qual avaliou-se a virulência e crescimento vegetativo, produção de conídios em meio de cultura, arroz e em cadáveres de broca. Destacaram-se três isolados de B. bassiana (UNIOESTE 4, UNIOESTE 52 e UNIOESTE 64, e um de M. anisopliae (IBCB 352, atingindo mortalidade confirmada igual ou superior a 90% na primeira etapa, sendo estes selecionados para etapa posterior, juntamente com isolado padrão, CG 716. O isolado IBCB 352 de M. anisopliae, apesar de ser o único da espécie a ser selecionado para a segunda etapa, provocou a maior mortalidade confirmada e conidiogênese em cadáveres de broca, indicando uma elevada produção de inóculo, sendo este, o indicado para a campo.

    Some insects use host and mate cues, including odor, color, and shape, to locate and recognize their preferred hosts and mates. Previous research has shown that the Asian longicorn beetle, Anoplophora glabripennis (Motschulsky), uses olfactory cues to locate host plants and differentiate them from non-host plants. However, whether A. glabripennis adults use visual cues or a combination of visual and olfactory cues remains unclear. In this study, we tested the host location and recognition behavior in A. glabripennis, which infests a number of hardwood species and causes considerable economic losses in North America, Europe and Asia. We determined the relative importance of visual and olfactory cues from Acer negundo in host plant location and recognition, as well as in the discrimination of non-host plants (Sabina chinensis and Pinus bungeana), by female and male A. glabripennis. Visual and olfactory cues from the host plants (A. negundo), alone and combined, attracted significantly more females and males than equivalent cues from non-host plants (S. chinensis and P. bungeana). Furthermore, the combination of visual and olfactory cues of host plants attracted more adults than either cue alone, and visual cues alone attracted significantly more adults than olfactory cues alone. This finding suggests that adult A. glabripennis has an innate preference for the visual and/or olfactory cues of its host plants (A. negundo) over those of the non-host plant and visual cues are initially more important than olfactory cues for orientation; furthermore, this finding also suggests that adults integrate visual and olfactory cues to find their host plants. Our results indicate that different modalities of host plant cues should be considered together to understand fully the communication between host plants and Asian longhorned beetles.

    The entomopathogenic fungus Metarhizium brunneum (Petch) strain F52 (Hypocreales: Clavicipitaceae) is able to produce environmentally persistent microsclerotia (hyphal aggregates). Microsclerotia of strain F52 produced as granules and incorporated into hydromulch (hydro-seeding straw, water, and a natural glue) provides a novel mycoinsecticide that could be sprayed onto urban, forest, or orchard trees. We tested this formulation against adult Asian longhorned beetles (Anoplophora glabripennis (Motschulsky)) using three substrates (moistened bark, dry bark, absorbent bench liner) sprayed with a low rate (9 microsclerotia granules/cm2) of hydromulch. Median survival times of beetles continuously exposed to sprayed moist bark or absorbent liner were 17.5 and 19.5 d, respectively. Beetles exposed to sprayed dry bark, which had a lower measured water activity, lived significantly longer. When moist bark pieces were sprayed with increased rates of microsclerotia granules in hydromulch, 50% died by 12.5 d at the highest application rate, significantly sooner than beetles exposed to lower application rates (16.5-17.5 d). To measure fecundity effects, hydromulch with or without microsclerotia was sprayed onto small logs and pairs of beetles were exposed for a 2-wk oviposition period in containers with 98 or 66% relative humidity. At 98% humidity, oviposition in the logs was highest for controls (18.3±1.4 viable offspring per female) versus 3.9±0.8 for beetles exposed to microsclerotia. At 66% humidity, fecundities of controls and beetles exposed to microsclerotia were not significantly different. This article presents the first evaluation of M. brunneum microsclerotia in hydromulch applied for control of an arboreal insect pest.

    Feeding experiments with Asian longhorned beetles (Anoplophora glabripennis (Motschulsky)) in a quarantine laboratory were used to assess the effectiveness of imidacloprid in reducing adult fecundity and survival. The beetles were fed twigs and leaves cut between June-September 2010 from Norway maples (Acer platanoides L.) in the beetle-infested area of Worcester, MA. Treated trees had been trunk-injected once with imidacloprid in spring 2010 under the U.S. Department of Agriculture-Animal and Plant Health Inspection Service operational eradication program. The 21 d LC50 value for adult beetles feeding on twig bark from imidacloprid-injected trees was 1.3 ppm. Adult reproductive output and survival were significantly reduced when beetles fed on twig bark or leaves from treated trees. However, results varied widely, with many twig samples having no detectable imidacloprid and little effect on the beetles. When twigs with > 1 ppm imidacloprid in the bark were fed to mated beetles, the number of larvae produced was reduced by 94% and median adult survival was reduced to 14 d. For twigs with 1 ppm). When given a choice of control twigs and twigs from injected trees, beetles did not show a strong preference.

    2009-06-01

    We conducted a 2-yr study to determine the effects of crop density and weeds on levels of damage caused by stalk-boring insects in rain-fed sunflowers in west-central Kansas. Weed-free sunflower had higher seed weight and oil content in 2007, but not in 2006, but weeds did not affect infestation by stalk-boring insects in either year. High-density sunflower had lower estimated seed yield per unit area than low-density sunflower in both years, but percentage oil was slightly greater in the high-density treatment in 2006. Sunflowers were more heavily infested by larvae of Ataxia hubbardi Fisher, Cylindrocopturus adspersus (Leconte), and Pelochrista womanana (Kearfott) in 2006 than in 2007, ostensibly as a result of being planted earlier. Larvae of Dectes texanus LeConte appeared unaffected by planting date and were present in > 70% of plants in both years. Conditions during the period of crop maturity were much drier in 2006 than in 2007 and were associated with higher seed oil content and earlier and faster progression of stalk girdling by D. texanus larvae in both low- and high-density plots. There was also a strong effect of plant density on girdling behavior that seemed to be mediated by effects on soil moisture. Stalk girdling began earlier in high-density plots and a larger proportion of plants were girdled compared with low-density plots on all sampling dates in both years. Certain cultural tactics, in particular reduced plant spacing, have potential to delay the onset of girdling behavior by D. texanus larvae and thus mitigate losses that otherwise result from the lodging of girdled plants.

    Xylotrechus arvicola is an important pest in vineyards (Vitis vinifera) in the main Iberian wine-producing regions, and Acanthoscelides obtectus causes severe post-harvest losses in the common bean (Phaseolus vulgaris). Under laboratory conditions with a spray tower, the susceptibility of the immature stages of X. arvicola and A. obtectus against the entomopathogenic fungi Beauveria bassiana and four strains of Trichoderma spp. was evaluated. Both insect pests T. harzianum and B. bassiana showed a good inhibitory activity, accumulating an inhibition on the eggs of values above 85 and 82%, respectively. T. atroviride and T. citrinoviride had a lower inhibitory activity, with inhibition values of 74.1 and 73.3% respectively. These fungi can be considered a highly effective tool for the control during the immature stages of these species.

    We conducted two field trapping experiments with multiple-funnel traps in 2008 and one experiment in 2010 to determine the effects of lure placement (inside or outside funnels) on catches of saproxylic species of beetles (Coleoptera). The experiments were conducted in southern pine (Pinus spp.) stands in central Georgia using combinations of ethanol, alpha-pinene, ipsenol, and ipsdienol lures. We report on a modification to the multiple-funnel trap that allows placement of large lures inside the confines of the funnels with minimal blockage. In general, catches of five species of common longhorn beetles (Cerambycidae), two species of regeneration weevils (Curculionidae), four species of bark beetles (Curculionidae: Scolytinae), and seven species of beetle predators and ectoparasites (Cleridae, Histeridae, Tenebrionidae, Trogossitidae, and Zopheridae) were higher in funnel traps with lures attached inside the funnels than in those with lures attached outside of the funnels. Catches of the remaining species were unaffected by lure placement. In no instance were catches of any species lower in funnel traps with lures attached inside the funnels than in those with lures attached outside of the funnels. For most species, catches in modified funnel traps with ethanol, alpha-pinene, ipsenol, and ipsdienol lures attached inside funnels were comparable with those in cross-vane panel traps.

    Wood-boring beetles in the family Cerambycidae (Coleoptera) play important roles in many forest ecosystems. However, increasing numbers of invasive cerambycid species are transported to new countries by global commerce and threaten forest health in the United States and worldwide. Our goal was to identify effective detection tools for a broad array of cerambycid species by testing some known cerambycid attractants and a pheromone in different trap designs placed across a range of habitats. We compared numbers and species richness of cerambycid beetles captured with cross-vane panel traps and 12-unit Lindgren multiple-funnel traps, placed either at ground level (1.5 m high) or canopy level (approximately 3-10 m high), at eight sites classified as either residential, industrial, deciduous forest, or conifer forest. We captured 3,723 beetles representing 72 cerambycid species from 10 June to 15 July 2010. Species richness was highest for the subfamilies Cerambycinae and Lamiinae, which accounted for 33 and 46% of all species captured, respectively. Overall, the cross-vane panel traps captured approximately 1.5 times more beetles than funnel traps. Twenty-one species were captured exclusively in traps at one height, either in the canopy or at ground level. More species were captured in hardwood sites (59 species) where a greater diversity of host material was available than in conifer (34 species), residential (41 species), or industrial (49) sites. Low numbers of beetles (n < 5) were recorded for 28 of the beetle species. The number of species captured per week ranged from 49 species on 21 June to 37 species on 12 July. Cross-vane panel traps installed across a vertical gradient should maximize the number of cerambycid species captured.

    The present paper is devoted to an overview on fossil Coleoptera studied from Inner Mongolia,Daohugou (Middle Jurassic,Jiulongshan Formation) and Liaoning (Upper Jurassic-Lower Cretaceous,Yixian Formation) deposited in Chinese collections.As a result,species of the tribe Sperchopsini and Hydrophilini from Hydrophilidae,families and subfamilies Silphidae,Syndesinae from Lucanidae,Pleocomidae,Trogidae,Trogissitidae,Pyrochroidae,Diaperinae from Tenebrionidae,and Cerambycidae were first registered in the Mesozoic and some families were defined as new.It was shown that many superfamilies represented in the Recent Fauna were formed within the Middle Jurassic and Lower Cretaceous.The materials examined confirm the hypothesis that Cucujiformian beetles are a younger group than other infraordera of Polyphaga (Staphyliniformia and Elateriformia) and,therefore,they appeared in the fossil record only in the late Mesozoic.It was shown and confirmed that most superfamilies appeared in the fossil records before Cucujoidea.The synonymy of Notocupes Ponomarenko,1964;Sinocupes Lin,1976,syn.nov.;Amblomma Tan,Ren et Liu 2005,syn.nov.;Euryomma Tan,Ren et Shih,2006,syn.nov.,non Stein,1899 and Ovatocupes Tan et Ren,2006,syn.nov.;synonymy of Tetraphalerus Waterhouse,1901 and Odontomma Tan,Ren et Ge 2006,syn.nov.;and synonymy of Priacmopsis Ponomarenko,1966 and Latocupes Tan et Ren,2006,syn.nov.are proposed.Sinorhombocoleus papposus Tan et Ren,2009 is transferred from the family Rhombocoleidae to Schizophoridae.Cervicatinius complanus Tan,Ren et Shih,2007 and Forticatinius elegans Tan,Ren et Shih,2007 are transferred from the family Catiniidae (suborder Archostemata) to superfamily Cleroidea (suborder Polyphaga:first among the family Peltidae and second as a closely related group to the latter family).The family Parandrexidae is transferred from the superfamily Cucujoidea to Cieroidea.The ecological circumstances of the past ecosystems and hypotheses of historical development of the order

    In this study, the nearly complete sequence (14,519 bp) of the mitochondrial DNA (mtDNA) of the entomophagous endoparasite Xenos vesparum (Insecta: Strepsiptera) is described. All protein coding genes (PCGs) are in the arrangement known to be ancestral for insects, but three tRNA genes (trnA, trnS(gcu), and trnL(uag)) have transposed to derived positions and there are three tandem copies of trnH, each of which is potentially functional. All of these rearrangements except for that of trnL(uag) is within the short span between nad3 and nad4 and there are numerous blocks of unassignable sequence in this region, perhaps as remnants of larger scale predisposing rearrangements. X. vesparum mtDNA nucleotide composition is strongly biased toward As and Ts, as is typical for insect mtDNAs. There is also significant strand skew in the distribution of these nucleotides, with the J-strand being richer in A than T and in C than G, and the N-strand showing an opposite skew for complementary pairs of nucleotides. The hypothetical secondary structure of the 16S rRNA has also been reconstructed, obtaining a structural model similar to that of other insects.

    Full Text Available Due to the importance of some Pleurosticti Scarabaeidae as agricultural pests allied to information absence on the species that occur in Brazilian Central-West region, on studies occurrence, biology and behavior on this group of scarabs were conducted. Biology and behavioral studies started with Liogenys fuscus Blanchard, 1850 (Melolonthinae, a very common species and were developed in Aquidauana, Mato Grosso do Sul. Adult beetles were collected from light traps from February 2005 to January 2007, at the experimental farm of the Universidade Estadual de Mato Grosso do Sul in Aquidauana (UEMS. In the laboratory adults were placed in plastic containers with soil with sprouts of Brachiaria decumbens Stapf (Poaceae. Eggs were transferred to a climatized chamber at 26 ± 1º C with a 12hourlight, 12hour darkness photoperiod cycle. Adult flight activity occurred in August and in September to December from 06:00 pm to 06:00 am, with the largest number of individuals flying from 07:00 to 10:00 pm. Eggs measured 1 x 1.5 mm and were laid individually or in groups in soil chambers; eggs were initially white and became yellow near hatching. The embryonic period lasted 14.3 days; first, second and third instars lasted 28.5, 48.8, and 68.2 days, respectively. The prepupal period lasted 120.2 days and the prepupa stayed inactive in soil. The mean duration of pupal stage was 27.5 days and the mean longevity of adults was 23.6 days. In laboratory the calling behavior between males and females was observed; copulation lasted, in mean, 25 minutes.Devido à importância de alguns Scarabaeidae Pleurosticti como causadores de danos à agricultura, aliada à ausência de informações sobre as espécies que ocorrem na região Centro Oeste, foram desenvolvidos estudos sobre a ocorrência, biologia e comportamento sobre este grupo de escarabeídeos. Foram iniciados com Liogenys fuscus Blanchard, 1850 (Melolonthinae, espécie muito comum em Aquidauana, Mato Grosso do Sul, Brasil. Na fazenda experimental da Universidade Estadual de Mato Grosso do Sul (UEMS, campus de Aquidauana, foi instalada diariamente, armadilha luminosa, de fevereiro de 2005 a janeiro de 2007 para coleta dos adultos. Os adultos coletados foram encaminhados para laboratório e acondicionados em caixas de plástico, contendo solo e mudas de Brachiaria decumbens Stapf (Poaceae. Foi possível obter ovos e realizar os estudos de biologia, em câmara climatizada a 26 ± 1º C e fotofase de 12 horas. Os adultos revoaram entre agosto e setembro a dezembro nos dois anos de estudos, nos horários das 18h00 às 6h00, em maior quantidade das 19h00 às 22h00. Os ovos, de 1,5 x 1,0 mm, foram depositados no solo individualmente ou agrupados em câmaras; possuem coloração branca e quando estão próximos da eclosão adquirem cor amarela. O período embrionário durou 14,3 dias, o primeiro, segundo e terceiro instares duraram 28,5, 48,8 e 68,2 dias respectivamente. O período de prépupa, que permaneceu inativa no solo, durou 120,2 dias. A fase de pupa durou em média de 27,5 dias e os adultos apresentaram longevidade média de 23,6 dias. Em laboratório foi observado comportamento de chamamento entre machos e fêmeas e a cópula durou em média 25 minutos.

    Full Text Available Information about Scarabaeidae phytophagous are still rare for the Center-West Region of Brazil. Thus, in the experimental area of the Universidade Estadual do Mato Grosso do Sul, in Aquidauana, Mato Grosso do Sul State, Brazil, the succession of soybean, maize, and forage turnip was sowed from February 2004 to October 2005, when the larvae population dynamics was evaluated. From October 2006 to May 2008, nine succession systems were sowed, the larval density evaluated, and the identification of the current species was carried out. When the larvae were sampled for soybean, in January 2005 and 2006, the highest densities were found in the field (3.44 larvae m-2 and 4.19 larvae m-2, respectively. The forage turnip, sampled in October 2004 and 2005, showed the lowest densities (0.03 larvae m-2 and 0.02 larvae m-2, respectively. In the crop succession systems, the following species were found: Liogenys fuscus Blanchard (highest amount, Liogenys bidenticeps Moser, Anomala testaceipennis Blanchard, Paranomala inconstans (Burmeister, Geniates borelli Camerano, Cyclocephala forsteri Endrodi, Cyclocephala verticalis Burmeister, and Phyllophaga sp. For the succession systems with maize sowed at the traditional season, the highest larval densities were found, specially favoring the development of L. fuscus, while the succession systems with soybean, maize, and under fallow, and soybean, crotalaria, and forage turnip, as well as the three systems with cotton-plant, did not favor it.

    KEY-WORDS: Zea mays; Glycine max; Raphanus sativus; soil pests; larvae density.Informações sobre Scarabaeidae fitófagos são ainda escassas para a região Centro-Oeste do Brasil. Por esta razão, na área experimental da Universidade Estadual do Mato Grosso do Sul, em Aquidauana (MS, foi semeada, de fevereiro de 2004 a outubro de 2005, a sucessão de culturas soja, milho e nabo forrageiro, onde se avaliou a dinâmica da densidade larval. De outubro de 2006 a maio de 2008, foram realizadas semeaduras de nove sistemas de sucessão de culturas, sendo avaliadas as densidades larvais e identificadas as espécies ocorrentes. Quando se amostraram as larvas na cultura da soja, em janeiro de 2005 e 2006, encontraram-se as maiores densidades (3,44 larvas m-2 e 4,19 larvas m-2, respectivamente, no campo. O nabo forrageiro, amostrado em outubro de 2004 e 2005, apresentou as menores densidades (0,03 larvas m-2 e 0,02 larvas m-2, respectivamente. Nos sistemas de sucessão de culturas, as espécies encontradas foram Liogenys fuscus Blanchard, Liogenys bidenticeps Moser, Anomala testaceipennis Blanchard, Paranomala inconstans (Burmeister, Geniates borelli Camerano, Cyclocephala forsteri Endrodi, Cyclocephala verticalis Burmeister e Phyllophaga sp, sendo que  L. fuscus foi coletada em maior quantidade. Para os sistemas de sucessão que possuem o milho semeado na safra, foram encontradas as maiores densidades larvais, indicando que esta cultura favorece o desenvolvimento, principalmente, de L. fuscus, enquanto os sistemas de sucessão com soja, milho e pousio, e soja, crotalária e nabo forrageiro, bem como os três sistemas com o algodoeiro, lhe são desfavoráveis.

    Full Text Available Teratology is the study of malformations that affect various organisms and may cause taxonomic confusion. The goal of this work is to compile the previously published information about malformations in species of Staphylinidae, to describe 10 teratological cases that have not been previously recorded in neotropical species of this family, and to point out the high frequency of these malformations in the studied specimens. The previously recorded cases were obtained from review of 13 papers, and the studied specimens were obtained on loan from several collections. In total, 43 teratological cases were compiled for Staphylinidae, belonging to 39 species from 8 subfamilies. Ten teratological cases are described for specimens from Belonuchus, Agrodes and Plochionocerus. One of them occurs in B. apiciventris, 2 in A. elegans, 3 in P. humeralis, 3 in P. fulgens and 1 in P. splendens. Most of the anomalies affect the antennae (7 cases, but teratologies that affect mandibles (1 case, midlegs (1 case and pronotum (1 case are also presented.Teratología es el estudio de las malformaciones que afectan a distintos organismos y que pueden causar confusiones taxonómicas.

    As molecular identification method, DNA barcoding based on partial cytochrome c oxidase subunit 1 (COI) sequences has been proven to be a useful tool for species determination in many insect taxa including ground beetles. In this study we tested the effectiveness of DNA barcodes to discriminate species of the ground beetle genus Bembidion and some closely related taxa of Germany. DNA barcodes were obtained from 819 individuals and 78 species, including sequences from previous studies as well as more than 300 new generated DNA barcodes. We found a 1:1 correspondence between BIN and traditionally recognized species for 69 species (89%). Low interspecific distances with maximum pairwise K2P values below 2.2% were found for three species pairs, including two species pairs with haplotype sharing (Bembidion atrocaeruleum/Bembidion varicolor and Bembidion guttula/Bembidion mannerheimii). In contrast to this, deep intraspecific sequence divergences with distinct lineages were revealed for two species (Bembidion geniculatum/Ocys harpaloides). Our study emphasizes the use of DNA barcodes for the identification of the analyzed ground beetles species and represents an important step in building-up a comprehensive barcode library for the Carabidae in Germany and Central Europe as well.

    Full Text Available A new species of the genus Tasmanitachoides Erwin from North Queensland is described: T. glabellus n. sp. The species belongs to the T. murrumbidgensis¿group of species that is characterized by its distinctly impressed clypeus, but it is distinguished from all related species by its glabrous body surface. It is the first Tasmanitachoides from northern Australia to be found in rainforest on high mountains and has thus probably preserved the original habits of the genus that are still characteristic for those species living in southern temperate regions of Australia. Tasmanitachoides lutus (Darlington so far known from the type locality in southern New South Wales and from the holotype only, is now recorded from eastern Victoria.

    Full Text Available Biology and growth performance of Red Stripe Weevil, Rhynchophorus schach Oliv. were studied using meridic diets. The diets consisted of sugarcane (Saccharum officinarum L. bagasse, copra (Cocos nucifera L. cake and sago (Metroxylon sagus Rottb. flour as main ingredients. Larvae or locally known as sagoworm, in copra cake diet exhibited the fastest growth with maximum weight gain of 1609 mg in week 5, while those of sugarcane bagasse diet had slowest growth with peak weight gain of 1024 mg in week 9. Sago flour diet gave the longest larval period at 96.3 days with the highest final larval weight of 8132.1 mg. The R. schach larvae had 8 instars. Head capsule width within each instar was constant irrespective of diets given. Instar period was dependent on diets given and varied from 6.3-12 days. Pupal duration ranged from 38.5-41 days. Adult emergence was 90%. Sago flour diet had the heaviest pupae and adults. Male weevils emerged earlier than the females, but females lived 10-13 days longer. Fecundity was low at 67 eggs per female but the hatchability was 92%. Life cycle for the insect ranged from 130.2-138.8 days, with a lifespan of 178.2-183.8 days. Larvae raised on sago flour diet had the highest fat content at 57.8% but with the lowest fiber at 4.7%. Larvae were generally rich in Mg, Ca, Zn and Fe, but low in Cu. This study showed that sago flour constituted the most suitable diet. The results also suggested that growth and development of the weevil could be further improved by incorporating copra cake and sugarcane bagasse into the sago flour diet. Larvae could be readily mass produced as a source of nutritious food, besides its potential use as a laboratory test organism.

    Full Text Available The fumigant efficacy of 1,8-cineole and eugenol compounds was tested on the pupal stage of the red flour beetle Tribolium castaneum (Herbst. Effects of those compounds were determined as mortality as well as impact on development of treated male and female pupae. Also differences in sensitivity to the tested compounds between sexes of T. castaneum pupae were assessed. Compounds were tested at 3 doses rate 0.34, 0.86 and 1.71 ml L-1 vol. at 30±1°C and 70±10% r.h. during 48 h. Compounds toxicity was expressed in two action modes: lethal, and as an impediment to normal metamorphosis of pupae into adult stage, forming "adultoids" and deformed adults (at both sexes. Male pupae were generally more sensitive to both tested compounds. Overall, better efficiency was performed with 1,8-cineole, while eugenol had not accomplished promising effect on the tested pupae.

    Between 1998 and 2007, the California Academy of Sciences (CAS) was the lead institution in a multi-national, multi-disciplinary biodiversity inventory project in the Gaoligong Shan region (GLGS) in the Yunnan province of China. The project surveyed the species diversity of both higher plants and bryophytes, fishes, amphibians, reptiles, birds, mammals and selected groups of arachnids and insects. The GLGS of China is one of the most biodiverse areas in all of Asia, yet it is also very poorly sampled and in great threat from increasing human activities in the region. CAS's biodiversity inventory project there has increased the number of carabid species known from just 50 to more than 550 species, an eleven-fold increase. The task that remains is to identify all of those 500 additional species and describe any that are new to science. This project is part of that larger biodiversity survey. Our objective was to identify and/or describe carabid beetles of the tribe Cyclosomini represented by nearly a hundred specimens collected in the GLSG. Among those specimens, six morphospecies were identified - one belonging to the genus Cyclosomus Latreille 1829, and the other five belonging to the genus Tetragonoderus Dejean 1829. Following this initial identification process, a list of known distributions of taxa in both genera was assembled to determine which described species to consider for comparative work. Original descriptions were then located for candidate species with known distributions in or near the GLGS; and these are being used now in morphological comparison of specimens. Type specimens for each of the candidate species have been requested from various academic institutions, and morphological comparisons with these types are underway. Morphological characteristics being examined include body proportions and overall shape, color of appendages, color and shape of pronotum, elytral color patterns, and shape and internal structure of male genitalia.

    2015-04-08

    The genus group name Monophyllus Kluge, 2012 was established to include a single species of the mayfly family Leptophlebiidae (Insecta: Ephemeroptera) from Hainan Island, China, Choroterpes (Monophyllus) monophyllus Kluge, 2012. Unfortunately, this name is preoccupied by Monophyllus Leach, 1821, a genus of Phyllostomidae bats (Mammalia: Chiroptera) from the Antilles (type species: M. redmani Leach, 1821: 76). Therefore, we propose a replacement name for the mayfly genus group as follows.

    The original description of Afraustraloderes rassei Bouyer, 2012 included a female that is now recognized as a separate species belonging to the genus Pixodarus and here described as Pixodarus spiniscapus sp. n. The true female of Afraustraloderes rassei has also been obtained recently and is, therefore, here described. The synonymy of Pixodarus exasperatus with Pixodarus nyassae, proposed earlier by Santos Ferreira (1980), is here supported. Conversely, the earlier inclusion of Afraustraloderes rassei in the tribe Hopliderini is rejected, on the basis of a key set of characters established by Quentin and Villiers (1972, 1975). Afraustraloderes rassei appears to be restricted to the Cape Floral Region, exhibiting larval development in trunks and roots of dead Proteaceae plants. Conversely, Pixodarus spiniscapus has so far only been recorded in the eastern part of South Africa and appears to be associated with bushveld vegetation.

    General estimation of ribosomal DNA variation within the class Insecta is presented. It is shown that, using blot-hybridization, one can detect differences in the structure of the ribosomal gene cluster not only between genera within an order, but also between species within a genera, including sibling species. Structure of the ribosomal gene cluster of the Coccinellidae family (ladybirds) is analyzed. It is shown that cloned highly conservative regions of ribosomal DNA of Tetrahymena pyriformis can be used as probes for analyzing ribosomal genes in insects. 24 refs., 4 figs.

    Full Text Available Carabid beetles (Coleoptera, Carabidae are one of the most studied soil groups in relation to heavy metal (HM accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators of HM accumulation appears to be rather limited.

    Perfluorooctane sulfonic acid (PFOS) is a persistent and ubiquitous environmental contaminant that has been detected in organisms worldwide. Here, we evaluate whether long-term (1 and 4 months) exposure to PFOS contamination affects the behavioural performance of freshwater larvae of the damselfly Enallagma cyathigerum (Insecta: Odonata). Our results show reduced behavioural performance with increasing PFOS concentration. In 1 month exposed larvae, no observed effect concentrations (NOECs) were 100 {mu}g/L for general activity. In 4 months exposed larvae, NOECs were 10 {mu}g/L, for each behavioural trait, except swimming acceleration of male larvae where the NOEC was 100 {mu}g/L. When faced with PFOS concentrations above the NOEC, E. cyathigerum larvae were less active, less capable to escape a simulated predator attack and less efficient in foraging. Together, our results show that damselfly larvae suffer reduced survival-related behavioural performance. - Long-term laboratory exposure to perfluorooctane sulfonic acid decreases behavioural performance of damselfly larvae (Insecta: Odonata)

    Full Text Available RESUMEN. Apagomerella versicolor es un cerambícido cuyas larvas barrenan los tallos de plantas compuestas de los géneros Xanthium, Ambrosia y Pluchea (Asteraceae. En la Argentina se distribuye entre los 25º y 39º de LS. Estudios sobre la biología de este insecto realizados con poblaciones de los alrededores de Buenos Aires (35º S, indicaban que era una especie univoltina con diapausa larval durante el invierno y que se podía inducir la salida del estado de diapausa exponiendo las larvas a bajas temperaturas. Sin embargo algunas observaciones sugerían que poblaciones del norte del país podían ser bi o multivoltinas sin diapausa larval. En este trabajo estudiamos el voltinismo y la diapausa en una clina latitudinal entre los 25 y los 32º de LS. Se realizó un ensayo para revelar la presencia de diapausa.en las distintas latitudes, para ello, larvas de distintas latitudes fueron separadas en dos grupos, uno fue expuesto a un tratamiento de bajas temperaturas para romper la diapausa y el otro fue utilizado como control. Aquellas larvas que presentaran diapausa y recibieran un tratamiento de frío deberían empupar más rápidamente que aquellas que no fueron tratadas. Además se realizaron 10 viajes al área de estudio en los meses de enero, marzo, julio, agosto, octubre y diciembre en distintos años donde se revisaron las principales plantas huéspedes: Pluchea sagittalis Cabr. y Xanthium cavanillesii Schouw. Se observaron los estadios inmaduros presentes en las diferentes plantas según la latitud. La evidencia encontrada sugiere que A. versicolor es al menos bivoltina entre los 25 y los 27º de LS y que presenta diapausa en latitudes mayores a los 31º. Se discute la influencia de las plantas huéspedes sobre el voltinismo y la diapausa larval en poblaciones de A. versicolor.ABSTRACT. Apagomerella versicolor (Boheman, a long horn stem-borer beetle of the host genera Pluchea., Xanthium, and Ambrosia (Asteraceae. In Argentina, it occurs between 25 and 39 o S. Studies conducted in Buenos Aires (35 o S indicated that A. versicolor is univoltine and has a winter diapause, and also indicate that diapuse larvae exposed to low temperatures broke the diapuse. However, some observations suggested that populations from northern Argentina could be bi or multivoltine and did not diapause. The voltinism and the diapause of A. versicolor were studied along its latitudinal distribution, between 25 and 32 o S. We conducted an experiment to identify diapause presence; larvae collected at different latitudes were separate in two groups, one of them were exposed to low temperatures to break the diapause, the other one was control. Those diapausing larvae that received cold treatment should pupate in a shorter time than those that did not receive it. In addition, ten collecting trips were made in January, March, July, August, October and December in different years in the study area to observe the immature stages present in its main hosts, Pluchea sagittalis Cabr. and Xanthium cavanillesii Schouw, at different latitudes. It was found evidence that A. versicolor is at least bivoltine between 25 º and 27 o S, and it does diapause at latitudes over 31 o S. The influence of the biology of the host plants on voltinism and diapause is discussed here.

  9. Novel Primers From Informative Nuclear Loci for Louse Molecular Phylogenetics (Insecta: Phthiraptera).

    While parasitic lice (Insecta: Phthiraptera) have historically been an important model taxon for understanding host-parasite coevolution, very few molecular markers have been developed for phylogenetic analysis. The current markers are insufficient to resolve many of the deeper nodes in this group; therefore, sequences from additional genetic loci are necessary. Here, we design primers targeting several nuclear protein coding genes based on a complete genome and transcriptome of Pediculus humanus L. plus transcriptomes and modest coverage genomic data from five genera of avian feather lice. These primers were tested on 32 genera of avian feather lice (Ischnocera), including multiple species within some genera. All of the new primer combinations produced sequences for the majority of the genera and had similar or higher divergences than the most widely used nuclear protein-coding gene in lice, EF-1α. These results indicate that these new loci will be useful in resolving phylogenetic relationships among parasitic lice.

  10. The evolution of asymmetric genitalia in Coleoptera

    The evolution of asymmetry in male genitalia is a pervasive and recurrent phenomenon across almost the entire animal kingdom. Although in some taxa the asymmetry may be a response to the evolution of one-sided, male-above copulation from a more ancestral female-above condition, in other taxa, such as Mammalia and Coleoptera, this explanation appears insufficient. We carried out an informal assessment of genital asymmetry across the Coleoptera and found that male genital asymmetry is present in 43% of all beetle families, and at all within-family taxonomic levels. In the most diverse group, Cucujiformia, however, genital asymmetry is comparatively rare. We also reconstructed the phylogeny of the leiodid tribe Cholevini, and mapped aspects of genital asymmetry on the tree, revealing that endophallus sclerites, endophallus, median lobe and parameres are, in a nested fashion, increasingly unlikely to have evolved asymmetry. We interpret these results in the light of cryptic female choice versus sexually antagonistic coevolution and advocate further ways in which the phenomenon may be better understood. This article is part of the themed issue ‘Provocative questions in left–right asymmetry’. PMID:27821530

    Three complete mitochondrial genomes of Blaberidae (Insecta: Blattodea) (Gromphadorhina portentosa, Panchlora nivea, Blaptica dubia) and one complete mt genome of Blattidae (Insecta: Blattodea) (Shelfordella lateralis) were sequenced to further understand the characteristics of cockroach mitogenomes and reconstruct the phylogenetic relationship of Blattodea. The gene order and orientation of these four cockroach genomes were similar to known cockroach mt genomes, and contained 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and one control region. The mt genomes of Blattodea exhibited a characteristics of a high A+T composition (70.7%-74.3%) and dominant usage of the TAA stop codon. The AT content of the whole mt genome, PCGs and total tRNAs in G. portentosa was the lowest in known cockroaches. The presence of a 71-bp intergenic spacer region between trnQ and trnM was a unique feature in B. dubia, but absent in other cockroaches, which can be explained by the duplication/random loss model. Based on the nucleotide and amino acid datasets of the 13 PCGs genes, neighbor-joining (NJ), maximum parsimony (MP), maximum likelihood (ML) and bayesian inference (BI) analyses were used to rebuild the phylogenetic relationship of cockroaches. All phylogenetic analyses consistently placed Isoptera as the sister cluster to Cryptocercidae of Blattodea. Ectobiidae and Blaberidae (Blaberoidea) formed a sister clade to Blattidae. Corydiidae is a sister clade of all the remaining cockroach species with a high value in NJ and MP analyses of nucleotide and amino acid datasets, and ML and BI analyses of the amino acid dataset.

The holotype female is here described as A. aspinosus Björnstad, sp. n. Also, a new small series collected at Hogsback, in the Amathole range, has allowed the description of the previously unknown female of the type species, A. vivesi Adlbauer, 2008. Both species are high altitude dwellers, occurring above 1300 m asl and their habitat consists mainly of mountain grassland interspersed with mistbelt forest pockets. All specimens were recorded in the austral winter to early spring, when these mountain ranges are occasionally covered in snow and night temperature plummet below 0 °C. They appear to be nocturnal and their complete lack of wings indicates a remarkable adaptation to cold conditions at high altitude.

    Burrows within black-tailed prairie dog (Cynomys ludovicianus) colonies on the Rocky Mountain Arsenal National Wildlife Refuge, Colorado, were dusted with deltamethrin insecticide to reduce flea (Insecta: Siphonaptera) abundance. Flea populations were monitored pre- and posttreatment by combing prairie dogs and collecting fleas from burrows. A single application of deltamethrin significantly reduced populations of the plague vector Oropsylla hirsuta, and other flea species on prairie dogs and in prairie dog burrows for at least 84 d. A plague epizootic on the Rocky Mountain Arsenal National Wildlife Refuge caused high mortality of prairie dogs on some untreated colonies, but did not appear to affect nearby colonies dusted with deltamethrin.

    Bioinsecticidal effects of methanol extracts from seven plant species on Tribolium castaneum were investigated. Centaurium erythraea, Peganum harmala, Ajuga iva, Aristolochia baetica, Pteridium aquilinum and Raphanus raphanistrum extracts inhibit growth of larvae. C. erythraea was the most toxic with 63% mortality 10 days after treatment, followed by P. harmala with 58%. C. erythraea and P. aquilinum reduce the emergence rate respectively of 66% and 19%. The duration of larval period was shortened by Launaea arborescens, P. aquilinum and A. iva extracts, whereas R. raphanistrum and P. harmala extracts extend the larval period when compared to the control. Extracts of C. erythraea, P. harmala, A. iva and A. baetica inhibited F1 progeny production. Larvae possess three alpha-amylase isoforms as determined by SDS-PAGE. Larvae fed on treated diet had lower alpha-amylase activity than larvae feed on untreated diet. C. erythraea and P. harmala are the most potent extracts. These plant extracts could be useful to reduce seed damage caused by this pest species.

    Full Text Available The purpose of this study was to evaluate the integrity of two forest fragments in Rio Negro Pantanal sub-region, using coleopterans as environmental indicators. The study was carried out at Santa Emilia Farm in the Rio Negro sub-region, municipality of Aquidauana, Mato Grosso do Sul (19º 30' 18'' S and 55° 36' 45'' W. Two sites were selected, locally denominated as "cordilheiras" (narrow and elongated strands of elevated soil, one with low degree of anthropic disturbance (CL and the other, currently undergoing restoration process (TD. The sampling sites were determined using a GPS device. Ten pit-fall traps containing water and detergent were used for the specimens sampling, which were screened and identified. Abundance, richness, diversity and similarity were determined. Abundance was higher for CL (n = 277 than for TD (n = 251. The same was observed for the diversity indices, CL showed H' = 2.83 bit.individual-1 and TD = 2.48 bit.individual-1, confirming the interferences made for abundance. Specimens of ten families were captured in CL area and seven families in TD area, indicating higher richness in CL, when compared to TD. The linear correlation coefficient (p > 0.05 indicates that both areas are significantly different, showing similarity value of 66.7%. The data show that the structure and disturbance degree in the environment integrity influence the composition of beetles fauna, causing the increase of abundance, richness and diversity in anthropogenic environments undergoing the early stage of regeneration.

    Examining the succession pattern of carrion insects on vertebrate carcasses is widely accepted as an effective method to estimate the postmortem interval (PMI) of decayed bodies. Investigation of the community of sarcosaprophagous insects, especially flies and beetles, is the foundation of the succession pattern study. This study aimed to investigate the sarcosaprophagous beetles succession on animal carcasses in the suburban area of southwestern China and to establish a basic catalog for forensic application. The present study was conducted in 2013 in a mountain in Chongqing municipality with modified Schoenly traps. Carcasses of miniature pig were used to simulate human bodies. For most carcasses, five decomposition stages were observed. A total of 2108 adult coleopterans belonging to at least 61 species and 18 families were collected in the study, and most of the specimens occurred at the advanced decay stage. Omosita colon (Linnaeus, 1758), Necrodes nigricornis (Harold, 1875), Necrobia ruficollis (Fabricius, 1775) and Neosilusa ceylonica (Kraatz, 1857) were the dominant species.

    Full Text Available Conservation of mayflies (Insecta, Ephemeroptera in Espírito Santo, southeastern Brazil. Ephemeroptera exhibits great diversity among bodies of freshwater in the Atlantic Forest, a biome that is suffering from massive human impact. Within this context, the creation of conservation units using biological information is more recommended than economic, cultural, or political criteria. The distribution pattern of 76 Ephemeroptera species was analyzed using the biogeographical methods Parsimony Analysis of Endemicity and Network Analysis Method in order to infer relevant areas for conservation of the mayfly community in Espírito Santo. The results obtained from both analyses were largely congruent, and pointed out four relevant areas for conservation: two in the south of the state, where conservation units or priority areas for conservation are well established; and two in the north, a region in the state where little conservation efforts have been historically done. Therefore, based on our analyses on mayflies, we recommend the expansion of the existing APCs or the creation of new APCs on the north of Espírito Santo.

    Full Text Available Study of the mayfly order Ephemeroptera (Insecta in Brazil: a scienciometric review. Despite an increase in the number of studies in recent years of the aquatic insect order Ephemeroptera (the mayflies much still remains to be learnt. In order to identify the current state of knowledge of this group in Brazil, we performed a scienciometric analysis with the purpose of identifying the strong and weak points of Brazilian research into the group. Our research used the "Institute for Scientific Information - ISI" database and was based on the abstracts, titles and keywords of manuscripts published between 1992 and 2011. We selected the papers with the combination of the words "Ephemeroptera" and "Brazil*" based on a search in February 2012. We analyzed 92 articles, and noted a lack of studies in some Brazilian states, no specific studies about some families, and an absence of phylogenetic studies. To improve ecological studies, it is necessary to fine-tune taxonomic resolution. Moreover, there is a lack of studies investigating the environmental variables which influence the distribution of mayflies. Despite these gaps, if the rate of publication with mayflies proceeds at the same pace, we anticipate that many of these knowledge gaps will be closed.

    Silk products are used in medicine as biomaterials, and are particularly promising as scaffolds in tissue engineering. To date only silkworm and spider silk medical potential has been evaluated, whereas the possible application of the material spun by caddisflies in wet environment has not been examined. Biomedical application of every natural material requires biocompatibility testing and evaluation of unique microbiological and mechanical properties. This article focuses on silk fibers formed in caddisflies cocoons of Hydropsyche angustipennis (Insecta, Trichoptera) larvae. Preliminary biological evaluation shows that trichopteran silk is not cytotoxic to human cells. Caddisfly silk itself does not possess antiseptic properties and thus sterilization is indispensable for its application in medicine. Among tested methods of sterilization and disinfection only thermal methods (tyndallization and autoclaving) enabled complete eradication of bacteria and gave fully sterile material. Caddisfly silk appeared to be resistant to high temperature. Fully sterile fibers can be stored without a loss of breaking force and tensile strength. Our work shows that trichopteran silk has a significant potential to be used as a biomaterial.

    Full Text Available Abstract Background The true water bugs are grouped in infraorder Nepomorpha (Insecta: Hemiptera: Heteroptera and are of great economic importance. The phylogenetic relationships within Nepomorpha and the taxonomic hierarchies of Pleoidea and Aphelocheiroidea are uncertain. Most of the previous studies were based on morphological characters without algorithmic assessment. In the latest study, the molecular markers employed in phylogenetic analyses were partial sequences of 16S rDNA and 18S rDNA with a total length about 1 kb. Up to now, no mitochondrial genome of the true water bugs has been sequenced, which is one of the largest data sets that could be compared across animal taxa. In this study we analyzed the unresolved problems in Nepomorpha using evidence from mitochondrial genomes. Results Nine mitochondrial genomes of Nepomorpha and five of other hemipterans were sequenced. These mitochondrial genomes contain the commonly found 37 genes without gene rearrangements. Based on the nucleotide sequences of mt-genomes, Pleoidea is not a member of the Nepomorpha and Aphelocheiroidea should be grouped back into Naucoroidea. Phylogenetic relationships among the superfamilies of Nepomorpha were resolved robustly. Conclusion The mt-genome is an effective data source for resolving intraordinal phylogenetic problems at the superfamily level within Heteroptera. The mitochondrial genomes of the true water bugs are typical insect mt-genomes. Based on the nucleotide sequences of the mt-genomes, we propose the Pleoidea to be a separate heteropteran infraorder. The infraorder Nepomorpha consists of five superfamilies with the relationships (Corixoidea + ((Naucoroidea + Notonectoidea + (Ochteroidea + Nepoidea.

    Abundant well-preserved tubular fossils of caddisfly (Insecta: Trichoptera) larval cases are reported from the Early Cretaceous Madongshan and Naijiahe formations of the Liupanshan Basin, Ningxia Province, western China. Most cases were mainly preserved in life position and densely packed in various layers. Individual cases in each layer tended to be same in size and were erect and parallel to one another and open at both ends. In a transverse section cut perpendicular to the long axis of the cases, individual case appears to form a rounded ring. Small cases are elliptic in a cross-section oblique to the long axis of the cases. Tube walls are nearly subparallel to one another in longitudinal section with both ends being open. The caudal end of the case slightly tapers and usually points downward. The cases were closely packed, almost touching with one another and lacking bifurcate or connecting struc-ture. The overwhelming majority of cases were partially or fully filled with calcite. The case wall em-braces a medium particle layer flanked by inner and outer organic layers. Individual particles are ovate in outline and comprise cryptocrystalline or ganic pellets. SEM imaging shows that those pellets are sub-cylindrical in outline and elliptic in cross section, and are made primarily of calcium carbonate. All features observed justify the assignment of the Liupanshan caddisfly cases to ichnogenus Coprindusia. The extinct insect Ningxiapsyche fangi was found in association with the Liupanshan caddisfly larval cases, and thus could be the candidate of the potential trace-maker.

  4. Nocturnal Migration of Coleoptera: Carabidae in North China

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Vertical-looking radar (VLR) has allowed long-term automatic monitoring of the altitudinal and temporal dynamics of high-flying insect populations. To investigate whether ground beetle, insect of Coleoptera, was capable of migrating and its migration pattern by taking advantages of capability of the VLR for long-term real-time automatic monitoring, the migration of Coleoptera ground beetle was investigated by setting up radar observation points, making long-term observation using the VLR and related supplementary equipment, and analyzing low altitude air current and large area circulating current in combination with the meteorological data. Information obtained in 2005 and 2006 showed that the seasonal activities of ground beetles traps of trap lamps were mainly from late June to late August, peak period was mainly in August, seasonal traps of high-altitude lamps and ground lamps were featured by sudden increase and sudden decrease; in peak period, the height of radar echo point could be as high as 600 m, while it was mainly below the height of 450 m; night activities mainly occurred from 20:00 to 22:00, in very few nights, radar echo could last until about 04:00, changes in numbers of ground beetles within the searchlights were consistent with radar echo intensity; ground beetle images were successfully trapped in the sweep nets carried by captive balloons at the height of 200 m. Some species of Carabidaes had some degrees of migration, thus providing the foundation for investigating the migration of Coleoptera insects.

    The estimation of postmortem interval (PMI) based on successional patterns of adult insects is largely limited, due to the lack of potential PMI markers. Sex and size of adult insects could be easily used for such estimation. In this study, sex- and size-related patterns of carrion attendance by adult insects were analyzed in Necrodes littoralis (Coleoptera: Silphidae) and Creophilus maxillosus (Coleoptera: Staphylinidae). For both species, abundance of males and females changed similarly during decomposition. A slightly female-biased sex ratio was recorded in N. littoralis. Females of N. littoralis started visiting carcasses, on average, one day earlier than males. There was a rise in size of males of N. littoralis at the end of decomposition, whereas for females of both species and males of C. maxillosus, no size-related patterns of carrion visitation were found. Current results demonstrate that size and sex of adult carrion beetles are poor indicators of PMI.

When coordinates were not provided in specimens' labels, we used the locality information to search geographic coordinates in online gazetteers. We also separated the species by country for a country-species list. These data comprise 250 years of collections and taxonomic studies of Neotropical Muscidae and we expect that it provides a foundation and serves as guide for future studies of systematics and biogeography of the family.

    Full Text Available The blueberry, Vaccinium corymbosum L. (Ericaceae, is a shrub native to the northern Hemisphere introduced in Argentina, where it occupies small cultivated areas mainly in the provinces of Buenos Aires, Entre Ríos and Tucumán. At present, little is known about insects associated with this crop in Argentina. The aim of this study was to identify the species of Chrysomelidae present in blueberry crops in different regions of Argentina, and to present new chrysomelids-blueberry associations. Identification diagnosis, geographical distribution, association with other plants and aspects of their biology is given for each species. Seven species of crop-damaging Chrysomelidae were recorded in blueberry crops of Buenos Aires and Entre Rios. They belong to the subfamilies Galerucinae: Diabrotica speciosa (Germar, Disonychodes exclamationis (Boheman, Caeporis stigmula Germar, and Cacoscelis melanoptera Germar; Eumolpinae: Percolaspis varia (Lefèvre, and Spintherophyta semiaurata (Klug; and Cryptocephalinae: Lexiphanes coenobita Suffrian.El arándano, Vaccinium corymbosum L. (Ericaceae, es un arbusto nativo del hemisferio Norte, que fue introducido en la Argentina donde ocupa pequeñas áreas cultivadas, principalmente en las provincias de Buenos Aires, Entre Ríos y Tucumán. Hasta la actualidad, se conoce poco sobre los insectos asociados con este cultivo. El objetivo de este trabajo es relevar las especies de crisomélidos presentes en los cultivos de arándano de diferentes regiones, y aportar nuevas asociaciones crisomélidos-arándano para la Argentina. Para cada especie registrada, se brinda la diagnosis para su reconocimiento, su distribución geográfica, la asociación con otras plantas y algunos aspectos de su biología. Se registraron siete especies de Chrysomelidae que utilizan el arándano como recurso alimenticio en las provincias de Buenos Aires y Entre Ríos: subfamilia Galerucinae: Diabrotica speciosa (Germar, Disonychodes exclamationis (Boheman, Caeporis stigmula Germar, Cacoscelis melanoptera Germar; subfamilia Eumolpinae: Percolaspis varia (Lefèvre y Spintherophyta semiaurata (Klug; y subfamilia Cryptocephalinae: Lexiphanes coenobita Suffrian.

    Global trade facilitates the inadvertent movement of insect pests and subsequent establishment of populations outside their native ranges. Despite phytosanitary measures, nonnative insects arrive at United States (U.S.) ports of entry as larvae in solid wood packaging material (SWPM). Identification of wood-boring larval insects is important for pest risk analysis and management, but is difficult beyond family level due to highly conserved morphology. Therefore, we integrated DNA barcoding and rearing of larvae to identify wood-boring insects in SWPM. From 2012 to 2015, we obtained larvae of 338 longhorned beetles (Cerambycidae) and 38 metallic wood boring beetles (Buprestidae) intercepted in SWPM associated with imported products at six U.S. ports. We identified 265 specimens to species or genus using DNA barcodes. Ninety-three larvae were reared to adults and identified morphologically. No conflict was found between the two approaches, which together identified 275 cerambycids (23 genera) and 16 buprestids (4 genera). Our integrated approach confirmed novel DNA barcodes for seven species (10 specimens) of woodborers not in public databases. This study demonstrates the utility of DNA barcoding as a tool for regulatory agencies. We provide important documentation of potential beetle pests that may cross country borders through the SWPM pathway.

    Full Text Available Apagomerella versicolor es un cerambícido cuyas larvas barrenan los tallos de plantas compuestas de los géneros Xanthium, Ambrosia y Pluchea (Asteraceae. En la Argentina se distribuye entre los 25o y 39o de LS. Estudios sobre la biología de este insecto realizados con poblaciones de los alrededores de Buenos Aires (35o S, indicaban que era una especie univoltina con diapausa larval durante el invierno y que se podía inducir la salida del estado de diapausa exponiendo las larvas a bajas temperaturas. Sin embargo algunas observaciones sugerían que poblaciones del norte del país podían ser bi o multivoltinas sin diapausa larval. En este trabajo estudiamos el voltinismo y la diapausa en una clina latitudinal entre los 25 y los 32o de LS. Se realizó un ensayo para revelar la presencia de diapausa.en las distintas latitudes, para ello, larvas de distintas latitudes fueron separadas en dos grupos, uno fue expuesto a un tratamiento de bajas temperaturas para romper la diapausa y el otro fue utilizado como control. Aquellas larvas que presentaran diapausa y recibieran un tratamiento de frío deberían empupar más rápidamente que aquellas que no fueron tratadas. Además se realizaron 10 viajes al área de estudio en los meses de enero, marzo, julio, agosto, octubre y diciembre en distintos años donde se revisaron las principales plantas huéspedes: Pluchea sagittalis Cabr. y Xanthium cavanillesii Schouw. Se observaron los estadios inmaduros presentes en las diferentes plantas según la latitud. La evidencia encontrada sugiere que A. versicolor es al menos bivoltina entre los 25 y los 27o de LS y que presenta diapausa en latitudes mayores a los 31o. Se discute la influencia de las plantas huéspedes sobre el voltinismo y la diapausa larval en poblaciones de A. versicolor.

    By using EAG instrument and "Y" pipe, this study examined the EAG responses of Anoplophora glabripennis adults to 12 kinds of plant volatiles, including cis-3-hexen-l-ol, β-myr-cene, phellandrene, 3-carene, S-α-pinene, camphene, R-α-pinene, S-β-pinene, D-limonene, ocimene, ethyl acetate, and hexane at 5 concentrations, and the behavioral responses of the adults to 9 kinds of the volatiles, aimed to provide basic information for the development of at-tractants and repellents to A. glabripennsis. The antennae of the female and male adults had obvi-ous EAG responses to 12 kinds of the volatiles (except for the male adults to S-a-pinene), espe-cially at the concentrations of 0.4 and 2 mol·L-1. There exited significant differences (P<0.05 or P<0.01) in the feeling strength of the antennae to the volatiles between female and male adults. The results of behavior test showed that higher concentrations ocimene and β-myrcene had obvious repellent effect (P<0.01) (except myrcene to the female adults), S-a-pinene, S-β-pi-nene, ethyl acetate, β-a-pinene, phellandrene, and camphene had obvious attracting effect ( P< 0.01) (except S-α-pinene to the male adults and camphene to the female adults), whereas D-limonene had no obvious repellent and attracting effect on the male and female adults.%为给光肩星天牛引诱剂和驱避剂开发提供基础资料,采用触角电位仪和“Y”型管,测定光肩星天牛成虫对顺-3-烯-1-醇、月桂烯、水芹烯、3-蒈烯、S-α-蒎烯、莰烯、R-α-蒎烯、S-β-蒎烯、柠檬烯、罗勒烯、乙酸乙酯和正己烷等12种植物挥发物5个浓度的EAG和9种挥发物5个浓度的行为反应.结果表明:雌、雄虫触角对12种挥发物均有明显的EAG反应(S-α-蒎烯对雄虫除外),特别是在0.4和2mol·L-1两个浓度;雌、雄虫触角对挥发物的感受强度多存在显著差异(P<0.05或P<0.01).行为测试结果表明:较高浓度的罗勒烯、月桂烯2种挥发物具有明显的驱避作用(P<0.01)(雌虫对月桂烯无明显行为反应),S-α-蒎烯、S-β-蒎烯、乙酸乙酯、R-α-蒎烯、水芹烯、莰烯等6种挥发物具有明显的引诱作用(P<0.01)(雄虫对S-α-蒎烯、雌虫对莰烯,无明显行为反应);柠檬烯对雌、雄虫均无明显的驱、诱作用.

    为了探索云斑天牛Batocera lineolata Chevrolat雌雄成虫的交配机制,采用室内饲养观察和视频轨迹捕捉系统( EthoVision 3.1)自动记录分析相结合的方法,对云斑天牛的两性相遇行为进行了研究.行为仪分析结果表明,雌雌、雄雄与雌雄相遇过程中,雌雄在轨迹相交时间和净相对运动上显著长于雌雌和雄雄(P<0.05),而在反应前时间上显著短于雌雌和雄雄相遇情况(P<0.05).室内试验观察表明,云斑天牛成虫相遇包括避让、打斗和交配3种行为.雌雌相遇发生避让的频率最高为80.98% (P <0.05).雄雄相遇发生避让的频率为78.03%,显著高于发生打斗的频率21.96% (P <0.05);雌、雄成虫与正在交配的一对成虫相遇发生避让的频率显著高于另外3种行为[打斗(继续交配)、打斗(结束交配)、打斗(与后来者交配)](P<0.05),雌、雄成虫发生避让、打斗(继续交配)和打斗(结束交配)3种行为的发生频率存在性别差异(P<0.05);当雄雄相遇中成虫是初次相遇时,在发生打斗的频率上显著高于再次相遇(P<0.05),成虫在雄雄相遇发生避让的频率上,再次相遇显著高于初次相遇(P<0.05),雌雄成虫初次相遇发生交配的频率显著高于再次相遇的频率(P<0.05).云斑天牛成虫相遇行为的研究为研究云斑天牛召唤机制、性信息素的生物合成及成虫繁殖行为学提供了依据.%In order to search the mating system of male and female adults of the white-striped longhorn beetle, Batocera lineolata Chevrolat, we studied the encountering behavior of male and female of B. Lineolata by laboratory observation in combination with automatic record and analysis through video tracking capture system ( EthoVision 3.1). The test results by behavior instrument showed that the intersection time of two tracks and net relative movements between one male and one female were longer than that between one female and one female or between one male and one male during the encountering process (P <0. 05) , while their reaction time was shorter than that for female-female or male-male (P <0.05). In the laboratory experiment, it was observed that the encountering process of B. Lineolata included three behaviors, I. E., avoidance, fight and mating. During female-female encountering process, the maximum avoidance rate was 80.98% (P <0.05). In male-male encountering, the avoidance rate was 78.03% , which was much higher than the fight rate of 21. 96% (P < 0. 05). Avoidance rate between one male or female and a couple under mating process was much higher than that for another three behaviors, I.e., fight (continue to mate) , fight (finish mating) and fight (mate with new comers) (P<0. 05). There was a sexual difference ( P < 0. 05 ) in occurrence frequency of these three bahaviors, I. E., avoidance, fight (continue to mate) and fight (finish mating) between the male and the female. If it was the first encountering for two males, the fight rate was much higher than that for theirsecond encountering (P <0.05) , and the avoidance rate for their second encountering was much higher than that for the first time (P <0. 05). But the mating rate for the first encountering of a male and a female was much higher than that for their second encountering ( P < 0. 05 ). The study upon encountering behavior of B. Lineolata provides the basis for studying calling mechanism and sex pheromone biosynthesis of B. Lineolata as well as reproductive behavior of the adults.

    The spatial characteristics of larval galleries and mining behaviour of the coffee stem-borer, Acalolepta cervinus (Hope), were studied on their host plant, Coffea arabica L. Results showed that entry holes were centrally located on stems of 4 cm diameter. Older larvae than third instar preferred tnnnelling upward on the stems when diam eter at the entry hole is larger than 4 cm, but downward on less than 4 cm. The vertical distribution of entry holes skewed toward lower position of stems. The larvae preferred drilling holes beside protrusions, especially beside the bases of adjacent branches. More entry holes were located on the south-facing side of stems. Larvae boring hole on stem exhibited a strong location preference. This study helps us to understand larval tunnelling behaviour and to de velop the control methods against the target pest.%研究了咖啡旋皮天牛Acalolepta cervinus(Hope)韧皮部蛀道和木质部蛀道的空间特征,揭示了其幼虫的蛀道行为特性.结果显示,钻蛀孔集中分布于咖啡树径4 cm处,当钻蛀孔处树径大于4 cm时,木质部蛀道大多向上发展,当小于4 cm时则向下发展;钻蛀孔在树干上的垂直分布则显示钻蛀孔多分布于靠近树干基部的区域;钻蛀孔多紧临树干上的凸起物旁,如侧枝基部、瘤凸旁等;较多数的钻蛀孔位于树干的南面.以上结果说明咖啡旋皮天牛幼虫的钻蛀行为具有很强的位置选择性.这一研究有助于我们进一步理解咖啡旋皮天牛幼虫的钻蛀行为,进而找到具有针对性的防治措施.

    We present a synthesis of the state of knowledge concerning the species of Passalidae (Coleoptera) of the West Indies and we present a key to the species. The recently described genus Antillanax Boucher renders the subgenus Passalus (Pertinax) Kaup paraphyletic, therefore we place Antillanax in synonymy with Passalus (Pertinax) and we propose a new combination for Passalus (Pertinax) doesburgi (Boucher). The island richest in species is Hispaniola, with five species, three of them endemic. Excluding Trinidad and Tobago, the passalid fauna of the West Indies comprises 13 species; this is low richness, but with high endemism (50%), especially for the Greater Antilles.

    The first synopsis of Mesozoic weevils (Curculionoidea: Coleoptera) is presented.Changes of family,genera and species abundance during the Mesozoic revealed three distributional patterns.The Jurassic (Karatau) fauna was dominated by the Nemonychidae.During the Early Cretaceous (beginning at the Jurassic/Cretaceous border),the Ithyceridae was the prevalent group with a significant role played by the Nemonychidae.In the Late Cretaceous (Cenomanian and Turonian),the major groups were the Curculionidae and Brentidae.Obviously,the change of weevil fauna during this period was due to the expansion of the angiosperms,which provided multiple niches in their vegetative and reproductive organs for weevil development.

    Full Text Available Rove beetles of medical importance in Brazil (Coleoptera, Staphylinidae, Paederinae. The rove beetles of the genus Paederus Fabricius, 1775 are the most important group within Coleoptera causing dermatitis around the world. The medical importance of Paederus depends on its toxic hemolymph released when these beetles are crushed on human skin. The effects are mainly dermatitis linearis and some sporadic cases of conjunctivitis. In Brazil seven species of Paederus are known to cause dermatitis: P. amazonicus Sharp, 1876, P. brasiliensis Erichson, 1840, P. columbinus Laporte, 1835, P. ferus Erichson, 1840, P. mutans Sharp, 1876, P. protensus Sharp, 1876 stat. rev., and Paederus rutilicornis Erichson, 1840. Paederus mutans and P. protensus are for the first time recorded as of medical importance, whereas the record of P. rutilicornis in Brazil is doubtful. All seven species are redescribed and a dichotomous key is provided. The geographic distributions of all species are documented. The results provided here include the most recent and relevant taxonomic revision of Paederus of the Neotropical region, the first identification key for Brazilian species and the increase of recorded species of medical importance in the world.

    B chromosomes have so far been described in about 80 species of Coleoptera, mainly using conventional staining analysis. In this study, 152 individuals of the dung beetle Dichotomius sericeus (Coleoptera), collected from three isolated geographical areas in the State of Pernambuco, Brazil, were analyzed to determine the frequency, prevalence, distribution, meiotic behavior, and possible B chromosome origin. The cytogenetic analysis consisted of conventional staining, C-banding, triple fluorochrome staining (CMA3/DA/DAPI), and fluorescent in situ hybridization using ribosomal DNAs (rDNAs) and H3 histone gene as probes, as well as microdissection and chromosome painting of the B chromosome. The B chromosomes were detected in all populations analyzed. Analysis revealed the heterochromatic nature and the presence of G+C-rich blocks and 18S rDNA on the B chromosome. FISH with DNA from microdissected B chromosome painted the entire extension of the B chromosome for all populations, besides the pericentromeric regions of all the autosomes, as well as the X chromosome. Finally, cross-hybridization in nine related species of Dichotomius using the microdissected B chromosome as probe did not reveal any hybridization signal. The results suggest an intraspecific and monophyletic origin for B chromosomes in D. sericeus, probably from the second or third autosomal pair.

    [Objective]Longhorn beetles are important trunkborer pests of forests and can cause serious damage to forest ecosystem; some insects in cerambycidae,such as Monochamus alternatus,Anoplophora glabripennis,are even important quarantine pests. Many insects use visual,olfactory,gustatory and auditory cues to locate and recognize their preference host plants and mates. In the last few decades a great deal of work has been devoted to olfactory sense and chemical ecology. It is well known that the visual sensory system is also one of the important sensory systems of insects and plays a vital role in the behavior activities of host and mate location and recognition and so on,however,study on it is relative less compared with the research on olfactory system in the influence of behavior activities of longhorn beetle,especially the review of visual mechanism of cerambycidae is not reported. [Method]The database of Web of Science and Google Scholar,the Chinese journal full-text database of the China National Knowledge Infrastructure ( CNKI ) were used to systematically search for publication relevant to visual system of cerambycidae. This paper not only introduces the characteristic anatomy structure of the visual organ of cerambycidae,but also reviews roles the visual system plays for the host and mate location and recognition of cerambycidae,as well as the utilization of research results on visual mechanism in the integrated pest management of forests. [Result]The adult of longicorn beetle possess two compound eyes,each of which is divided into two parts by antenna. The eyes occupy lateral position on either side of the head and surround the basal of antenna and the shape is kidney type and belongs to acone eye and pseudocone eye. Every ommatidium has eight retinula cells,and two central retinula cells are surrounded by six peripheral cells. The distinctions of diurnal and nocturnal longicorn beetles are mainly based on ommatidium density and the ratio of area of rhabdoms

    Forest canopies support high arthropod biodiversity, but in temperate canopies, little is known about the spatial distribution of these arthropods. This is an important first step toward understanding ecological roles of insects in temperate canopies. The objective of this study was to assess differences in the species composition of two dominant and diverse taxa (Diptera and Coleoptera) along a vertical gradient in temperate deciduous forest canopies. Five sugar maple trees from each of three deciduous forest sites in southern Quebec were sampled using a combination of window and trunk traps placed in three vertical strata (understory, mid-canopy, and upper-canopy) for three sampling periods throughout the summer. Coleoptera species richness and abundance did not differ between canopy heights, but more specimens and species of Diptera were collected in the upper-canopy. Community composition of Coleoptera and Diptera varied significantly by trap height. Window traps collected more specimens and species of Coleoptera than trunk traps, although both trap types should be used to maximize representation of the entire Coleoptera community. There were no differences in abundance, diversity, or composition of Diptera collected between trap types. Our data confirm the relevance of sampling all strata in a forest when studying canopy arthropod biodiversity.

The Adolpho Ducke Forest Reserve (ADRF is a fragment of 10.000 hectares in geographic conflict with the city of Manaus. The knowledge of the diversity of Ephemeroptera in the ADRF is essencial because these organisms are biological important elements as food source and for its potential as indicative of the human disturbances. The objective of this study was to develop a survey of the diversity of Leptophlebiidae from two basins of ADRF, comparing the diversity between basins and the dry and rainy periods 38 points were collected from streams of the Eastern (Ipiranga, Uberê and Tinga and Western (Acará and Bolivia ADRF basins with aquatic entomological net (rapiché. To verify differences in the wealth of the two basins and to compare the wealth in the dry and rainy periods it was utilized the Jackknife wealth index. It was colleded 804 larvae of Leptophlebiidae, being identified 368 individuals from seven genera: Hagenulopsis Ulmer (35%; n=128; Thraulodes Ulmer (34%; n=124; Farrodes Peters (13%; n=48; Miroculis Edmunds Jr (12%; n=45; Hydrosmilodon Flowers & Dominguez (5%; n=19; Hermanella Needham & Murphy (0.8%; n=3, Microphlebia Savage & Peters (n=1. It represents the first register of Hydrosmilodon, Hermanella and Microphlebia for the ADRF. In the comparison between the basins East and West, the Jackknife’s did not indicate significant difference in the wealth of genera. Hermanella and Hydrosmilodon had not occurred in the West basin and, Microphlebia did not occurred in the East basin, however these absences does not represent significant difference in the taxonomic wealth of the basins.

    Macrophytes in oxbow lakes represent an important substrate for the Coleoptera. Two oxbow lakes the Rio Paranapanema were studied and the other two Rio Mogi-Guaçu, in the State de São Paulo, Brasil. In this study, there is greater similarity between the communities of Coleoptera of lakes greater connectivity with the main river channel or the difference in the species of Salvinia collected in the lakes studied interferes Coleoptera fauna that uses as substrate. A total of 9,222 specimens of Coleoptera were collected and identified in 10 families and 40 genera. The analysis MDS for abundance of Coleoptera showed the grouping of the oxbow lakes the Paranapanema River and a distancing the oxbow lakes the Mogi-Guaçu. The PERMANOVA test did not reveal any difference in the fauna between the wet and dry periods. It was concluded that the connectivity between river and lake is not decisive for the richness and abundance of aquatic fauna of Coleoptera. Therefore, the richness and abundance of aquatic Coleoptera associated vary with the species of Salvinia used as substrate.

    Full Text Available During verifications of museum material for the Catalogue of the Palaearctic Coleoptera, the type specimen of Hylobius huguenini Reitter, 1891 conserved in the Hungarian National Museum was examined. The type specimen had been found by Gustav Huguenin in the Emmental region in Switzerland. The species was never found again and remained therefore mysterious. After the examination of the type specimen, it became clear that Hylobius huguenini belongs to the American genus Heilipodus Kuschel, 1955 (comb. nov., and there it ranks as a good species next to Heilipodus goeldii sp. nov., described here, and H. polyspilus (Pascoe, 1889, both from Brazil. The type specimens of Heilipodus goeldii sp. nov. were found in the Emil August Göldi-collection in the Natural History Museum of the Burgergemeinde Bern.

    2014-04-01

    Wireworms (Coleoptera: Elateridae), the subterranean larval stage of the click beetle, are becoming more prevalent in many cropping systems and posing an increasing economic threat to wheat growers in the Pacific Northwest following the cancellation of the insecticide lindane in 2006. Current insecticide seed treatments alone are not adequate for wireworm control. The objective of this study was to evaluate a diverse set of 163 wheat genotypes for tolerance to wireworm feeding. Entries were planted in replicated field trials over 3 yr and evaluated for their performance when grown in the presence of wireworms. Entries were rated based on survival and given a tolerance score. Results indicated that differences exist among wheat genotypes in their level of tolerance to wireworm feeding. In particular, consistently high-ranking genotypes of interest may be 'BR 18', 'Sonalika', 'Safed Lerma', and 'Hollis'. These genotypes, used in conjunction with other cultural or chemical control methods, may help provide an economic means of controlling wireworms.

    Full Text Available Track analysis of the Neotropical Entimini (Coleoptera, Curculionidae, Entiminae. Distributional patterns of the species belonging to the tribe Entimini from the Neotropical region were analyzed. Based on a track analysis of 22 species of Entimus, Rhigus, and Phaedropus, for which distributional data were available, two generalized tracks were found. One is located in northern Brazil, corresponding to the Amazonian subregion, and is determined by Phaedropus candidus and Rhigus speciosus. The other is located in southern Brazil, corresponding to the Parana subregion, and is determined by Entimus imperialis, E. excelsus, Phaedropus togatus, Rhigus dejeanii, R. faldermanni, R. horridus, R. lateritus, R. nigrosparsus, and R. tribuloides. The development of the Chacoan subregion is hypothesized to have been the dynamic vicariant event that fragmented the former Amazonian-Parana forest.Análisis de trazos de Entimini Neotropical (Coleoptera, Curculionidae, Entiminae.

    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.

    Most forensic studies are focused on Diptera pattern colonization while neglecting Coleoptera succession. So far, little information is available on the postmortem colonization by beetles and the decomposition process they initiate under temperate biogeoclimatic countries. These beetles have, however, been referred to as being part of the entomofaunal colonization of a dead body. Forensic entomologists need increased databases detailing the distribution, ecology, and phenology of necrophagous insects, including staphylinids (Coleoptera, Staphylinidae). While pig carcasses are commonly used in forensic entomology studies to surrogate human decomposition and to investigate the entomofaunal succession, very few works have been conducted in Europe on large carcasses. Our work reports the monitoring of the presence of adult rove beetles (Coleoptera, Staphylinidae) on decaying pig carcasses in a forest biotope during four seasons (spring, summer, fall, and winter). A total of 23 genera comprising 60 species of rove beetles were collected from pig carcasses.

También se realizan comparaciones de la diversidad de carábidos chilenos con respecto a otros países y el Neotrópico. Para Chile, se conocen 21 tribus, con 95 géneros y 365 especies, que representan el 38,8, 28,8 y 7,9 % de la fauna del Neotrópico, respectivamente. Chile posee un bajo número de tribus comparado con otros países, sin embargo, constituye un área importante por la presencia de seis tribus relictuales, principalmente pangeicas o gondwánicas. Chile posee 18 géneros endémicos (18,5 % de su fauna de Carabidae, 28 cuya distribución está restringida a Chile y Argentina y seis restringidos a Chile, Argentina y Uruguay. La cantidad de especies presentes en Chile es inferior a la que poseen otros países de América del Sur, pero la cantidad de especies endémicas es muy alta (204 y representa el 55,8 % de su fauna de carábidos. El alto grado de endemismo que posee Chile con respecto a otros países de América del Sur puede deberse a su condición de aislamiento, siendo las barreras más importantes la región desértica del norte y la cordillera de Los Andes. Este hecho también se vislumbra por la ausencia de importantes tribus neotropicales como Galeritini, Scaritini y Brachinini.

    The aquatic Coleoptera of a prairie wetland complex in Stutsman County, North Dakota, were collected from April 1979 to November 1980. Identification of 2594 individuals confirmed 57 species, including seven new records for North Dakota. Two seasonally flooded and two semipermanent wetlands, totaling 7.43 ha, contained 53% of the Dytiscidae, 43% of the Haliplidae, 38% of the Hydrophilidae, and 22% of the Gyrinidae species previously identified from North Dakota. Although 49.1% of the Coleoptera species occurred in both types of wetlands, the occurrence of 29 species varied by wetland class.

    Long-grain rice cultivars Cocodrie, Wells, and XP 723 grown in three locations (Hazen, MO; Essex and Newport, AR, USA), and medium-grain rice cultivars Bengal and XP 713 grown in two locations (Jonesboro and Lodge Corner, AR, USA), were harvested and assayed for susceptibility to Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), the lesser grain borer, and Sitophilus oryzae (L.) (Coleoptera: Curculionidae), the rice weevil, on rice held at 27℃ 57% and 75% relative humidity (RH).Separate samples from the same harvest lots were also analyzed for the physical characteristics of brown rice yield, percentage whole kernels and kernel thickness. Progeny production and feeding damage of R. dominica were significantly different among long-grain cultivars within two of the three locations (P < 0.05), but not for location or RH (P ≥ 0.05), while progeny production of S. oryzae was different among cultivars, location, and RH (P < 0.05). On medium-grain rice, both cultivar and location were significant for progeny production of R. dominica, but not RH, while cultivar and RH were significant for progeny production of S. oryzae, but not location. On both rice types, feeding damage of R. dominica followed the same trends and was always strongly positively correlated with progeny production (P < 0.05), but for S. oryzae there were several instances in which progeny production was not correlated with feeding damage (P ≥ 0.05). Physical characteristics of both rice types were statistically significant (P < 0.01) but actual numerical differences were extremely small, and were generally not correlated with progeny production of either species. Results indicate that the location in which a particular rice cultivar is grown, along with its characteristics, could affect susceptibility of the rice to R. dominica and S. oryzae.

    Hosts-parasite interactions are plentiful and diverse, and understanding the patterns of these interactions can provide great insight into the evolutionary history of the organisms involved. Estimating the phylogenetic relationships of a group of parasites and comparing them to that of their hosts can indicate how factors such as host or parasite life history, biogeography, or climate affect evolutionary patterns. In this study we compare the phylogeny generated for a clade of parasitic chewing lice (Insecta: Phthiraptera) within the genus Columbicola to that of their hosts, the small New World ground-doves (Aves: Columbidae). We sampled lice from the majority of host species, including samples from multiple geographic locations. From these samples we sequenced mitochondrial and nuclear loci for the lice, and used these data to estimate phylogenetic trees and population networks. After estimating the appropriate number of operational taxonomic units (OTUs) for the lice, we used cophylogenetic analyses to compare the louse phylogeny to an existing host phylogeny. Our phylogenetic analysis recovered significant structure within the louse clade, including evidence for potentially cryptic species. All cophylogenetic analyses indicated an overall congruence between the host and parasite trees. However, we only recovered a single cospeciation event. This finding suggests that certain branches in the trees are driving the signal of congruence. In particular, lice with the highest levels of congruence are associated with high Andean species of ground-doves that are well separated altitudinally from other related taxa. Other host-parasite associations are not as congruent, and these often involved widespread louse taxa. These widespread lice did, however, have significant phylogeographic structure, and their phylogenetic relationships are perhaps best explained by biogeographic patterns. Overall these results indicate that both host phylogeny and biogeography can be

    A new separation method involving hydrophilic interaction chromatography with tandem mass spectrometric detection has been developed for the analysis of pteridines, namely biopterin, isoxanthopterin, leucopterin, neopterin, xanthopterin and erythropterin in the cuticle of heteropteran insect species. Two columns, Atlantis HILIC Silica and ZIC(®)-HILIC were tested for the separation of these pteridines. The effect of organic modifier content, buffer type, concentration and pH in mobile phase on retention and separation behavior of the selected pteridines was studied and the separation mechanism was also investigated. The optimized conditions for the separation of pteridines consisted of ZIC(®)-HILIC column, mobile phase composed of acetonitrile/5mM ammonium acetate, pH 6.80, 85/15 (v/v), flow rate 0.5mL/min and column temperature 30°C. Detection was performed by tandem mass spectrometry operating in electrospray ionization with Agilent Jet Stream technology using the selected reaction monitoring mode. The optimized method provided a linearity range from 0.3 to 5000ng/mL (r>0.9975) and repeatability with relative standard deviation<8.09% for all the studied pteridines. The method was applied to the analysis of pteridines in the cuticle of larvae and three adult color forms of Graphosoma lineatum and one form of Graphosoma semipunctatum (Insecta: Hemiptera: Heteroptera: Pentatomidae). The analysis shows that different forms of Graphosoma species can be characterized by different distribution of individual pteridines, which affects the coloration of various forms. Only isoxanthopterin was found in all the five forms tested.

This study constitutes the first record of Temnocephala Blanchard, an ectosymbiont on Corydalidae, as a possible predator of chironomid larvae. Twenty-eight Corydalidae larvae (Corydalus and Protochauliodes were examined under stereomicroscopic in search for Temnocephala and Chironomidae larvae, of which five megalopteran larvae had 24 Temnocephala sp. associated. Furthermore, eight of these Temnocephala worms had chironomid larvae in their gut contents, an interaction previously unknown. Gut content analyses revealed Corynoneura as the commonest chironomid, but larvae of Larsia, Rheotanytarsus and Tanytarsus were recorded as well. This study included Corydalus and Protochauliodes as hosts for Temnocephala, which might be important for this worm dispersion and population dynamics.

    The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae), is a serious pest of coffee worldwide. It was first detected in Hawai'i in 2010. Two predatory beetles, Cathartus quadricollis (Coleoptera: Silvanidae) and Leptophloeus sp. (Coleoptera: Laemophloeidae), have been observed in H. hampei-infested coffee. Under laboratory conditions, colony-reared C. quadricollis and Leptophloeus sp. prey upon all life stages of H. hampei. However, the H. hampei life cycle occurs almost exclusively within a coffee bean obscured from direct observation. Thus, it is unknown if C. quadricollis and Leptophloeus sp. consume H. hampei as prey in the wild. To demonstrate predation of H. hampei by C. quadricollis and Leptophloeus sp., a molecular assay was developed utilizing species-specific primers targeting short regions of the mitochondrial COI gene to determine species presence. Using these primers, wild C. quadricollis and Leptophloeus sp. were collected and screened for the presence of H. hampei DNA using PCR. Analysis of collections from five coffee farms revealed predation of C. quadricollis and Leptophloeus sp. on H. hampei. Further laboratory testing showed that H. hampei DNA could be detected in predators for as long as 48 h after feeding, indicating the farm-caught predators had preyed on H. hampei within 2 d of sampling. This study demonstrates the utility of molecular markers for the study of the ecology of predators and prey with cryptic behavior, and suggests C. quadricollis and Leptophloeus sp. might be useful biocontrol agents against H. hampei.

    The objective of this work was to screen plants with insecticide activity, in order to isolate, identify and assess the bioactivity of insecticide compounds present in these plants, against Coleoptera pests of stored products: Oryzaephilus surinamensis L. (Silvanidae), Rhyzopertha dominica F. (Bostrichidae) and Sitophilus zeamais Mots. (Curculionidae). The plant species used were: basil (Ocimum selloi Benth.), rue (Ruta graveolens L.), lion's ear (Leonotis nepetifolia (L.) R.Br.), jimson weed (Datura stramonium L.), baleeira herb (Cordia verbenacea L.), mint (Mentha piperita L.), wild balsam apple (Mormodica charantia L.), and billy goat weed or mentrasto (Ageratum conyzoides L.). The insecticide activity of hexane and ethanol extracts from those plants on R. dominica was evaluated. Among them, only hexane extract of A. conyzoides showed insecticide activity; the hexane extract of this species was successively fractionated by silica gel column chromatography, for isolation and purification of the active compounds. Compounds 5,6,7,8,3',4',5'-heptamethoxyflavone; 5,6,7,8,3'-pentamethoxy-4',5'-methilenedioxyflavone and coumarin were identified. However, only coumarin showed insecticide activity against three insect pests (LD{sub 50} from 2.72 to 39.71 mg g{sup -1} a.i.). The increasing order of insects susceptibility to coumarin was R. dominica, S. zeamais and O. surinamensis. (author)

    The larvicidal activity of the dichloromethane extract of Zingiber purpureum Roscoe (Zingiberaceae) rhizome against the second instar of Aedes aegypti (L.) (Diptera: Culicidae) is shown to be due to 4-(3',4'-dimethoxyphenyl)buta-1,3-diene. The diene also showed ovicidal activity against the bruchid Callosobruchus maculatus (F.) (Coleoptera: Bruchidae). Most of the eggs laid by bruchids on treated cowpea seeds were transparent, and very few of them contained developing embryos. The few larvae produced from these embryos were unable to penetrate the seed coat and enter the seed. Similar effects were seen when adults were exposed to the compound and then placed on untreated cowpea seeds, suggesting that a new type of maternally mediated ovicidal effect was involved. Coated and impregnated granular formulations of the extract were evaluated for use in the control of bruchid infestation of stored cowpea seeds. Coated granules showed activity similar to that of the crude extract but were found to lose activity rapidly. Impregnated granules were found to be less active than the crude extract.

    The chromosome study of five species of the family Elateridae, belonging to the subfamilies Agrypninae and Elaterinae, and the analysis of the cytogenetic data previously recorded for this family permitted the establishment of the main strategies of karyotypic differentiation that has occurred in the elaterids. In Agrypninae, the three species studied (Conoderus fuscofasciatus, Conoderus rufidens, and Conoderus sp.) showed the male karyotype 2n=16+X0. This karyotypic uniformity detected in these Conoderus species has also been shared with other species of the same genus, differing considerably from chromosomal heterogeneity verified in the subfamily Agrypninae. The use of the C-banding technique in C. fuscofasciatus and Conoderus sp. revealed constitutive heterochromatin in the pericentromeric region of the majority of the chromosomes. In C. fuscofasciatus, additional constitutive heterochromatin were also observed in the long arm terminal region of almost all chromosomes. Among the representatives of Elaterinae, the karyotype 2n=18+Xy(p) of Pomachilius sp.2 was similar to that verified in the majority of the Coleoptera species, contrasting with the chromosomal formula 2n=18+X0 detected in Cardiorhinus rufilateris, which is most common in the species of Elaterinae. In the majority of the elaterids, the chromosomal differentiation has frequently been driven by reduction of the diploid number; but, among the four cytogenetically examined subfamilies, there are some differences in relation to the trends of karyotypic evolution.

    Click beetles (Coleoptera: Elateridae) represent one of the largest groups of beetle insects. Some click beetles in larval form, known as wireworms, are destructive agricultural pests. Morphological identification of click beetles is generally difficult and requires taxonomic expertise. This study reports on the DNA barcoding of Japanese click beetles to enable their rapid and accurate identification. We collected and assembled 762 cytochrome oxidase subunit I barcode sequences from 275 species, which cover approximately 75% of the common species found on the Japanese main island, Honshu. This barcode library also contains 20 out of the 21 potential pest species recorded in Japan. Our analysis shows that most morphologically identified species form distinct phylogenetic clusters separated from each other by large molecular distances. This supports the general usefulness of the DNA barcoding approach for quick and reliable identification of Japanese elaterid species for environmental impact assessment, agricultural pest control, and biodiversity analysis. On the other hand, the taxonomic boundary in dozens of species did not agree with the boundary of barcode index numbers (a criterion for sequence-based species delimitation). These findings urge taxonomic reinvestigation of these mismatched taxa.

  19. Economic analysis of emerald ash borer (Coleoptera: Buprestidae) management options.

    Emerald ash borer, Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), plays a significant role in the health and extent of management of native North American ash species in urban forests. An economic analysis of management options was performed to aid decision makers in preparing for likely future infestations. Separate ash tree population valuations were derived from the i-Tree Streets program and the Council of Tree and Landscape Appraisers (CTLA) methodology. A relative economic analysis was used to compare a control option (do-nothing approach, only removing ash trees as they die) to three distinct management options: 1) preemptive removal of all ash trees over a 5 yr period, 2) preemptive removal of all ash trees and replacement with comparable nonash trees, or 3) treating the entire population of ash trees with insecticides to minimize mortality. For each valuation and management option, an annual analysis was performed for both the remaining ash tree population and those lost to emerald ash borer. Retention of ash trees using insecticide treatments typically retained greater urban forest value, followed by doing nothing (control), which was better than preemptive removal and replacement. Preemptive removal without tree replacement, which was the least expensive management option, also provided the lowest net urban forest value over the 20-yr simulation. A "no emerald ash borer" scenario was modeled to further serve as a benchmark for each management option and provide a level of economic justification for regulatory programs aimed at slowing the movement of emerald ash borer.

    Full Text Available Biological aspects of Leucothyreus ambrosius Blanchard (Coleoptera, Melolonthidae, Rutelinae. Coleopterans of the family Melolonthidae comprise a large group of species that feed on different food sources, including plant roots, stems, and leaves, in addition to plant materials at different decomposition stages. Several species are found in the genus Leucothyreus, occurring in different regions of Brazil, including the various biomes in the country. Information on the biology of species of the genus Leucothyreus is scarce, therefore, we conducted studies on the biological aspects of Leucothyreus ambrosius Blanchard, 1850. The period of adult occurrence was determined with a light trap installed between a cropped and pasture area in the municipality of Aquidauana, Mato Grosso do Sul State, Brazil. Adults collected in the field were used to form insect pairs and the studies were initiated in the entomology laboratory as the adults began ovipositing. Adults were observed flying in the field from October to December. Eggs were obtained as pairs were formed and a colony was established, the embryonic period lasting 14.6 days on average. The larval period in the 1st instar lasted 21.6 days, in the 2nd instar 19.6 days, and in the 3rd instar, 85.6 days. The head capsule width was 1.48 mm in the 1st instar, 2.44 mm in the 2nd, and 3.83 mm in 3rd larval instar. The pupal stage had an average duration of 35.5 days. The egg to adult period lasted 173.3 days. Morphometric information for the larval and adult stages is presented in this study.

    Pitfall traps provide an easy and inexpensive way to sample ground-dwelling arthropods (Spence and Niemela 1994; Spence et al. 1997; Abildsnes and Tommeras 2000) and have been used exclusively in many studies of the abundance and diversity of ground beetles (Coleoptera: Carabidae). Despite the popularity of this trapping technique, pitfall traps have many disadvantages. For example, they often fail to collect both small (Spence and Niemela 1994) and trap-shy species (Benest 1989), eventually deplete the local carabid population (Digweed et al. 1995), require a species to be ground-dwelling in order to be captured (Liebherr and Mahar 1979), and produce different results depending on trap diameter and material, type of preservative used, and trap placement (Greenslade 1964; Luff 1975; Work et al. 2002). Further complications arise from seasonal patterns of movement among the beetles themselves (Maelfait and Desender 1990), as well as numerous climatic factors, differences in plant cover, and variable surface conditions (Adis 1979). Because of these limitations, pitfall trap data give an incomplete picture of the carabid community and should be interpreted carefully. Additional methods, such as use of Berlese funnels and litter washing (Spence and Niemela 1994), collection from lights (Usis and MacLean 1998), and deployment of flight intercept devices (Liebherr and Mahar 1979; Paarmann and Stork 1987), should be incorporated in surveys to better ascertain the species composition and relative numbers of ground beetles. Flight intercept devices, like pitfall traps, have the advantage of being easy to use and replicate, but their value to carabid surveys is largely unknown. Here we demonstrate the effectiveness of Malaise traps for sampling ground beetles in a bottomland hardwood forest.

  4. A family of chemoreceptors in Tribolium castaneum (Tenebrionidae: Coleoptera.

    Mohatmed Abdel-Latief

    Full Text Available Chemoperception in invertebrates is mediated by a family of G-protein-coupled receptors (GPCR. To date nothing is known about the molecular mechanisms of chemoperception in coleopteran species. Recently the genome of Tribolium castaneum was sequenced for use as a model species for the Coleoptera. Using blast searches analyses of the T. castaneum genome with previously predicted amino acid sequences of insect chemoreceptor genes, a putative chemoreceptor family consisting of 62 gustatory receptors (Grs and 26 olfactory receptors (Ors was identified. The receptors have seven transmembrane domains (7TMs and all belong to the GPCR receptor family. The expression of the T. castaneum chemoreceptor genes was investigated using quantification real- time RT-PCR and in situ whole mount RT-PCR analysis in the antennae, mouth parts, and prolegs of the adults and larvae. All of the predicted TcasGrs were expressed in the labium, maxillae, and prolegs of the adults but TcasGr13, 19, 28, 47, 62, 98, and 61 were not expressed in the prolegs. The TcasOrs were localized only in the antennae and not in any of the beetles gustatory organs with one exception; the TcasOr16 (like DmelOr83b, which was localized in the antennae, labium, and prolegs of the beetles. A group of six TcasGrs that presents a lineage with the sugar receptors subfamily in Drosophila melanogaster were localized in the lacinia of the Tribolium larvae. TcasGr1, 3, and 39, presented an ortholog to CO(2 receptors in D. melanogaster and Anopheles gambiae was recorded. Low expression of almost all of the predicted chemoreceptor genes was observed in the head tissues that contain the brains and suboesophageal ganglion (SOG. These findings demonstrate the identification of a chemoreceptor family in Tribolium, which is evolutionarily related to other insect species.

    Seago, Ainsley E; Brady, Parrish; Vigneron, Jean-Pol; Schultz, Tom D

    2009-04-01

    Members of the order Coleoptera are sometimes referred to as 'living jewels', in allusion to the strikingly diverse array of iridescence mechanisms and optical effects that have arisen in beetles. A number of novel and sophisticated reflectance mechanisms have been discovered in recent years, including three-dimensional photonic crystals and quasi-ordered coherent scattering arrays. However, the literature on beetle structural coloration is often redundant and lacks synthesis, with little interchange between the entomological and optical research communities. Here, an overview is provided for all iridescence mechanisms observed in Coleoptera. Types of iridescence are illustrated and classified into three mechanistic groups: multilayer reflectors, three-dimensional photonic crystals and diffraction gratings. Taxonomic and phylogenetic distributions are provided, along with discussion of the putative functions and evolutionary pathways by which iridescence has repeatedly arisen in beetles.

    The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), is a worldwide pest of stored grains. Using "Y"-tube olfactometry we studied the response of T. castaneum to odors from simulated wheat infestations containing conspecifics, and infestations containing the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), and the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae). Tribolium castaneum larvae were significantly attracted to odors from all three test species. Tribolium castaneum adults were attracted to grains infested by R. dominica and flour infested by T. castaneum but repelled from grains infested by S. granarius. Further behavioral analysis with pheromones showed that T. castaneum were significantly attracted to their aggregation pheromone, dimethyldecanal (DMD), but not to the R. dominica aggregation pheromone, a mixture of dominicalure 1 and 2. Female T. castaneum adults were attracted to ∼50-fold less DMD than larvae and 100-fold less than male adults, suggesting they are more sensitive to DMD. This study improves our understanding of T. castaneum behaviors to infested grain volatile compounds and pheromones, and may help develop new control methods for grain pest species.

  3. Higher level phylogeny and the first divergence time estimation of Heteroptera (Insecta: Hemiptera based on multiple genes.

    Directory of Open Access Journals (Sweden)

    Min Li

    Full Text Available Heteroptera, or true bugs, are the largest, morphologically diverse and economically important group of insects with incomplete metamorphosis. However, the phylogenetic relationships within Heteroptera are still in dispute and most of the previous studies were based on morphological characters or with single gene (partial or whole 18S rDNA. Besides, so far, divergence time estimates for Heteroptera totally rely on the fossil record, while no studies have been performed on molecular divergence rates. Here, for the first time, we used maximum parsimony (MP, maximum likelihood (ML and Bayesian inference (BI with multiple genes (18S rDNA, 28S rDNA, 16S rDNA and COI to estimate phylogenetic relationships among the infraorders, and meanwhile, the Penalized Likelihood (r8s and Bayesian (BEAST molecular dating methods were employed to estimate divergence time of higher taxa of this suborder. Major results of the present study included: Nepomorpha was placed as the most basal clade in all six trees (MP trees, ML trees and Bayesian trees of nuclear gene data and four-gene combined data, respectively with full support values. The sister-group relationship of Cimicomorpha and Pentatomomorpha was also strongly supported. Nepomorpha originated in early Triassic and the other six infraorders originated in a very short period of time in middle Triassic. Cimicomorpha and Pentatomomorpha underwent a radiation at family level in Cretaceous, paralleling the proliferation of the flowering plants. Our results indicated that the higher-group radiations within hemimetabolous Heteroptera were simultaneously with those of holometabolous Coleoptera and Diptera which took place in the Triassic. While the aquatic habitat was colonized by Nepomorpha already in the Triassic, the Gerromorpha independently adapted to the semi-aquatic habitat in the Early Jurassic.

    Under the framework of the DAISIE consortium, whose main mission is to make an inventory of the alien invasive species of Europe and its islands, we review the current state of knowledge and provide an up-to-date catalogue and distributional status for alien seed beetles (Coleoptera: Chrysomelidae: Bruchinae) in Europe. This work is based on studies of the species detected from the last century to the present, but with greater emphasis on the beginning of the 21st century, during which new biological studies have been carried out and findings made in European countries. The main objective of this paper is to focus on this last fact, which has promoted new views on the existing and potential threat of exotic bruchids in relation to climate change. This must now be regarded as a matter of concern for European agricultural and environmental policies. Only species of exotic origin introduced in European regions outside their native range were considered. Therefore, species of European origin spreading to new countries within Europe are not treated. Also, we provide a new approach to classifying alien seed beetle species according to their ability to become established, distinguishing between the well-established and those that may appear in seed stores but are not capable of invading natural and agricultural ecosystems. We present a taxonomic characterization of the alien bruchids found in Europe, providing an illustrated key based on external morphological characters of adults. The key facilitates the identification of the sixteen most frequently recorded genera, which represent 37 of the 42 species of exotic species recorded in Europe up to the present, whether established, not established or occasional. Finally, we provide a summary of the state of knowledge of the taxonomy and biology of the 20 most worrying species as pests, both established and non-established. This includes, where appropriate, an illustrated key for the identification of species. The study

  7. Acoustic Detection of Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) and Oryctes elegans (Coleoptera: Scarabaeidae) in Phoenix dactylifera (Arecales: Arecacae) Trees and Offshoots in Saudi Arabian Orchards.

    Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) larvae are cryptic, internal tissue-feeding pests of palm trees that are difficult to detect; consequently, infestations may remain hidden until they are widespread in an orchard. Infested trees and propagable offshoots that develop from axillary buds on the trunk frequently are transported inadvertently to previously uninfested areas. Acoustic methods can be used for scouting and early detection of R. ferrugineus, but until now have not been tested on multiple trees and offshoots in commercial date palm orchard environments. For this report, the acoustic detectability of R. ferrugineus was assessed in Saudi Arabian date palm orchards in the presence of commonly occurring wind, bird noise, machinery noise, and nontarget insects. Signal analyses were developed to detect R. ferrugineus and another insect pest, Oryctes elegans Prell (Coleoptera: Scarabaeidae), frequently co-occurring in the orchards, and discriminate both from background noise. In addition, it was possible to distinguish R. ferrugineus from O. elegans in offshoots by differences in the temporal patterns of their sound impulses. As has been observed often with other insect pests, populations of the two species appeared clumped rather than uniform or random. The results are discussed in relation to development of automated methods that could assist orchard managers in quickly identifying infested trees and offshoots so that R. ferrugineus infestations can be targeted and the likelihood of transferring infested offshoots to uninfested areas can be reduced.

    Three standard foodstuff plastic packaging namely polyethylene (PE), polypropylene (PP), and polyvinylchloride (PVC) were evaluated for management of lesser grain borer Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) and red flour beetle Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). Resistance parameters in packaging were recorded as punctures, holes, penetrations, sealing defects, and invasions with two thicknesses and tested for two lengths of time. Damages like punctures, holes and penetrations by both insects were more in PE packaging however R. dominica made more penetrations in PP than in PE. For both insects sealing defects and invasions were predominant in PVC than in others. Thickness did not affect significantly damage types but significantly more holes and penetrations by R. dominica were in less thickness. Punctures and holes by R. dominica were more after less time period but other damages in packaging were more after more time period. However for T. castaneum all sorts of damages were seen more after more time period. Overall categorization between two insects showed R. dominica made more penetrations and T. castaneum made more invasions compared with their counterparts. Pictures were taken under camera fitted microscope to magnify punctures and holes in different packaging and thicknesses. Insect mortality due to phosphine was more in PP and PE packaging and least in PVC packaging and thickness effect was marginal. T. castaneum mortality was significantly more after 48 h than after 24 h. Damages extent in packaging and fumigation results showed PP to be the best of three packaging materials to manage these insects.

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

    2008-03-01

    Previous research established different interactions of the insect pathogen, Xenorhabdus nematophila and nonpathogen, Bacillus subtilis, with antimicrobial hemocytes and humoral factors of larval Malacosoma disstria [Giannoulis, P., Brooks, C.L., Dunphy, G.B., Mandato, C.A., Niven, D.F., Zakarian, R.J., 2007. Interaction of the bacteria Xenorhabdus nematophila (Enterobacteriaceae) and Bacillus subtilis (Bacillaceae) with the hemocytes of larval Malacosoma disstria (Insecta: Lepidoptera: Lasicocampidae). J. Invertebr. Pathol. 94, 20-30]. The antimicrobial systems were inhibited by X. nematophila and stimulated by B. subtilis. The bacterial surface antigens participating in these reactions were unknown. Thus, herein the effects of lipopolysaccharide (endotoxin) from X. nematophila and lipoteichoic acid from B. subtilis on the larval M. disstria immune factors, the hemocytes and phenoloxidase, were determined. Endotoxin elevated the level of damaged hemocytes limiting the removal of X. nematophila from the hemolymph and enhancing the rapid release of bacteria trapped by nodulation. Similar effects were observed with the lipid A moiety of the endotoxin. The effects of lipopolysaccharide and lipid A on the hemocyte activities were abrogated by polymyxin B (an antibiotic that binds to lipid A) confirming lipopolysaccharide as the hemocytotoxin by virtue of the lipid A moiety. Lipoteichoic acid elicited nodulation and enhanced phenoloxidase activation and/or activity. Although lipoidal endotoxin and lipid A inhibited phenoloxidase activation they enhanced the activity of the enzyme. Apolipophorin-III precluded the effects of lipopolysaccharide, lipid A, and lipoteichoic acid on the hemocytes and prophenoloxidase until the antigens exceeded a critical threshold.

  14. New archaeorthopteran insects from the Late Carboniferous of the Nord and Pas-de-Calais basins in northern France (Insecta: Cnemidolestodea, Panorthoptera).

    2014-01-01

    New polyneopteran insects are described from Pennsylvanian (Bashkirian, Moscovian) compressed fossils from the North of France (Insecta: Archaeorthoptera). Discovery of wing apex with distinct venation, e.g., apical fusion of RA with RP, numerous parallel posterior branches of RP with transversal crossveins, can be assigned to cf. Tococladus sp. (Cnemidolestodea: Tococladidae). It represents the second record of Cnemidolestodea from the Avion locality apart from Aviocladus pectinatus Prokop et al., 2014. Bruaylogus magnificus gen. et sp. nov., based on forewing venation, is attributed to Panorthoptera nec Orthoptera having some distinct characters for the placement either close to Oedischiidae or a more basal position possibly with affinities to genus Heterologus. Aviologus duquesnei gen. et sp. nov., based on forewing venation, differs from Oedischiidae by the presence of basal fork of M far from point of separation between M and Cu and fusion of MA with first posterior branch of RP. Aviologus share a long stem of M and simple CuPaβ with Heterologus duyiwuer and H. langfordorum, but both differ in well separated median and radial veins. These new fossils demonstrate that the archaeorthopterid insect fauna from the North of France was rather diverse with links to late Carboniferous and early Permian assemblages in Euramerica such as the Mazon Creek, Carbondale Formation or Elmo, Wellington Formation (Illinois, Kansas, USA) entomofaunas.

    2002-02-01

    We investigated the phylogeny of the Braconidae (Insecta: Hymenoptera) with a much expanded data set compared with that of previous attempts, employing 16S and 28S rDNA gene fragments, together with a suite of morphological characters, from 74 ingroup taxa. Most notably, parsimony analyses under a range of models recovered the Aphidiinae as sister group to the cyclostomes and the Ichneutinae as sister group to the microgastroids. The cyclostomes were recovered as a natural group only if certain, putatively misplaced genera (Mesostoa, Aspilodemon) were excluded from them. Further, mapping of rearrangement characters onto this phylogeny of the Braconidae indicated parallel inversions of the mt-tRNAD gene, with the two instances of inversion distinguishable by the presence or absence of an additional tRNA gene (tRNAH). This is the first report of a parallel inversion of a mt-tRNA gene and makes the Braconidae the first metazoan family to display both parallel inversions and translocations.

    2014-11-01

    From 1994 to 2013, French forensic entomology laboratories investigated 1,093 cases. Larder beetles (Coleoptera: Dermestidae) were observed in 81 (7.5%) of these cases. To describe and analyze these 81 cases, eight parameters were used: city, location (indoor or outdoor), decay stage (fresh, decay, or dry), dermestid species and instar (adults and/or larvae), presence of living calliphorid larvae, presence of calliphorid pupae or adults, and presence of other necrophagous species. Eight Dermestidae species were observed: Dermestes frischii (42% of cases), Dermestes undulatus (35.8%), Dermestes peruvianus (12.3%), Dermestes lardarius (9.9%), Dermestes haemorrhoidalis (8.6%), Dermestes maculatus (7.4%), Dermestes bicolor (3.7%), and Dermestes ater (1.2%). Larder beetles primarily developed on human cadavers in outdoor locations in areas with a dry climate and were never reported in oceanic areas (which are characterized by frequent rainfall and high ambient humidity). The number of dermestid species on a single corpse never exceeded three. Typically, one species was found per corpse. Species differed between indoor and outdoor cases, with D. frischii and D. undulatus dominant in outdoor cases, while D. peruvianus dominant in indoor cases. Calliphoridae was found in 88% of the cases, while Hydrotaea and Piophilidae were observed 40% of the time. Regarding Coleoptera, Necrobia spp. (Coleoptera: Cleridae) was observed in 46% of the cases. Lastly, we observed a typical decomposition pattern, with preferential feeding areas on the face, hands, and feet (i.e., the extremities). Pupation chambers on or inside the bones were not observed.

    In May 1993, at the end of the rainy season, outbreaks of Paederus sabaeus (Coleoptera, Staphylinidae) were recorded in Brazzaville (Congo), Kinshasa (Zaire), Franceville and Libreville (Gabon) and even in Bangui (CAR) at the North of the equator. A short review of previous outbreaks in Africa and on vesicant substances is given by the authors. These beetles are attracted to neon lights and they rest on the walls or on the skin of the occupants. When the insects are crushed on the bare skin their haemolymph liberate pederine and related vesicant components which provocate dermatitis. The insects disappeared spontaneously after three to four weeks.

    We recorded the in vivo emission and time-resolved spectra of the firefly Luciola praeusta Kiesenwetter 1874 (Coleoptera : Lampyridae : Luciolinae). The emission spectrum shows that the full width at half maximum (FWHM) value for this particular species is 55 nm, which is significantly narrower than the in vivo half-widths reported till now. The time-resolved spectrum reveals that a flash of about 100 ms duration is, in fact, composed of a number of microsecond pulses. This suggests that the speed of the enzyme-catalysed chemiluminescence reaction in the firefly for the emission of light is much faster than was previously believed.

    Hastisetae are extremely elaborate and intricate insect setae that occur solely on dermestid larvae (Coleoptera: Dermestidae). The present work characterizes hastisetae found in mid-Cretaceous amber from Myanmar and compares them to hastisetae found on extant dermestid larvae. The presence of hastisetae in Myanmar amber shows that lineages of dermestid beetles had already developed hastisetae by the mid-Cretaceous and their presence allows us to follow the evolutionary development of this particular arthropod structure over the past 100 million years. Hastisetae attached to a parasitic wasp in the same piece of amber indicates that ancient dermestid beetles used their hastisetae for defense, similar to their function today.

  1. Evaluating Alpha and Beta Taxonomy in Ant-Nest Beetles (Coleoptera, Carabidae, Paussini

    Full Text Available We evaluated completeness, accuracy, and historical trend of the taxonomic knowledge on the myrmecophilous ground beetle tribe Paussini (Coleoptera, Carabidae, Paussinae. Accumulation curves for valid names and synonyms of species, subgenera, and genera were modelled using logistic functions. Analyses of trends in synonymies suggest that few currently accepted taxa will be recognized to be synonymous in the future. This may indicate that Paussini are a taxonomically relatively stable tribe of carabid beetles. However, this result might also be due to the lack of recent taxonomic work in some biogeographical regions.

    In electroantennographic tests isosafrol, methyl salicylate, (+/-)-lavandulol, geraniol, (E)-anethol, and beta-ionone evoked the largest responses from antennae of female or male Oxythyrea funesta (Coleoptera: Scarabaeidae, Cetoniinae) adult beetles. In field trapping tests in Hungary the 1:1 blend of (+/-)-lavandulol and 2-phenylethanol attracted significantly more adult O. funesta than the single compounds. The addition of (E)-anethol, a previously described attractant for the species, was without effect. There was no difference in the responses of male or female beetles. The binary 2-phenylethanol/(+/-)-lavandulol bait described, in this study is recommended for the use in traps of O. funesta for agricultural purposes.

    This paper describes for the first time the organization and fine structure of the central nervous system (CNS) in the fireflies, Pteroptyx tener (Coleoptera: Lampyridae). The morphology of the CNS was examined by using Carl Zeiss AxioScope A1 photomicroscope with iSolution Lite software. Some specific structural features such as the localization of protocerebrum, deutocerebrum and tritocerebrum in the brain region were analyzed. Other than that, the nerve cord and its peripheral structure were also analyzed. This study suggests that, there is a very obvious difference between male and female central nervous system which illustrates that they may differ in function in controlling physiological and behavioral activities.

    The elytra of male beetles Chlorophila obscuripennis (Coleoptera) display an inconspicuous iridescent bluish green color. By structural characterizations we find that the outermost elytral surface comprises a sculpted multilayer, which is the origin of structural coloration. In elytra both structural green and cyan colors are observed which arise from the modulations imposed on the multilayer, leading to a bluish green color by color mixing. The adoption of the sculpted multilayer can render structural coloration inconspicuous, which could be advantageous for camouflage. In addition, it can cause light emergence at nonspecular angles.

    Full Text Available During ecological investigations on saproxylic beetle communities of central Italy (Latium, at Bosco Polverino (a mixed evergreen/deciduous forest fragment dominated by cork oaks, and at Allumiere (a small fragment of beech forest surrounded by turkey oak stands, the authors found three specimens of Pityophagus quercus Reitter, 1877 (Coleoptera, Nitidulidae. These are the first known records of this species in Italy, and the first one in association with an evergreen oak, Quercus suber. This discovery led us to review both bionomical and faunistic data so far available on this exceedingly rare and poorly known species.

    Full Text Available Microtheca spp. (Coleoptera: Chrysomelidae are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS, southern Brazil, they are found on forage turnip, Raphanus sativus L. var. oleiferus Metzg., which is commonly grown during fall/winter seasons. This work reports the predation of Microtheca spp. larvae by Toxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae larvae, on forage turnip crop, in Santa Maria, RS. This register provides new information about Microtheca spp. natural enemies in Brazil, which might be a new option for integrate pest management of these species.

    The genus Pachycyphon is erected for marsh beetles (Coleoptera: Scirtidae) from tropical rainforests in Queensland, Australia. The following species are included: P. corpulentus sp. n., P. crassus sp. n., P. elegans sp. n., P. funicularis sp. n., P. gravis sp. n., P. monteithi sp. n., P. obesus sp. n., P. pinguis sp. n., P. serratus sp. n., P. turgidus sp. n. (the type species). Females are wingless and have fossorial ovipositors, a terrestrial larval life is therefore hypothesized. Pachycyphon is compared with other genera, especially probable relatives from temperate rainforests in southeastern Australia.

  18. Efficacies of spinosad and a combination of chlorpyrifos-methyl and deltamethrin against phosphine-resistant Rhyzopertha dominica (Coleoptera: Bostrichidae) and Tribolium castaneum (Coleoptera: Tenebrionidae) on wheat.

    Highly phosphine-resistant populations of Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) and Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) have recently been found in Oklahoma grain storage facilities. These findings necessitate development of a phosphine resistance management strategy to ensure continued effective use of phosphine. Therefore, we investigated the efficacies of two grain insecticides, namely, spinosad applied at label rate of 1 ppm and a mixture of chlorpyrifos-methyl and deltamethrin applied at label rates of 3 and 0.5 ppm, respectively, against highly phosphine-resistant R. dominica and T. castaneum. Adult mortality and progeny production suppression of spinosad- or chlorpyrifos-methyl + deltamethrin mixture-treated wheat that had been stored for 2, 84, 168, 252, and 336 d posttreatment were assessed. We found that both spinosad and chlorpyrifos-methyl + deltamethrin were effective against phosphine-resistant R. dominica and caused 83-100% mortality and also caused total progeny production suppression for all storage periods. Spinosad was not effective against phosphine-resistant T. castaneum; the highest mortality observed was only 3% for all the storage periods. Chlorpyrifos-methyl + deltamethrin was effective against phosphine-resistant T. castaneum only in treated wheat stored for 2 and 84 d, where it caused 93-99% mortality. However, chlorpyrifos-methyl + deltamethrin was effective and achieved total suppression of progeny production in T. castaneum for all the storage periods. Spinosad was not as effective as chlorpyrifos-methyl + deltamethrin mixture at suppressing progeny production of phosphine-resistant T. castaneum. These two insecticides can be used in a phosphine resistance management strategy for R. dominica and T. castaneum in the United States.

  1. The hydraulic mechanism in the hind wing veins of Cybister japonicus Sharp (order: Coleoptera

    2016-06-01

    Full Text Available The diving beetles (Dytiscidae, Coleoptera are families of water beetles. When they see light, they fly to the light source directly from the water. Their hind wings are thin and fragile under the protection of their elytra (forewings. When the beetle is at rest the hind wings are folded over the abdomen of the beetle and when in flight they unfold to provide the necessary aerodynamic forces. In this paper, the unfolding process of the hind wing of Cybister japonicus Sharp (order: Coleoptera was investigated. The motion characteristics of the blood in the veins of the structure system show that the veins have microfluidic control over the hydraulic mechanism of the unfolding process. A model is established, and the hind wing extending process is simulated. The blood flow and pressure changes are discussed. The driving mechanism for hydraulic control of the folding and unfolding actions of beetle hind wings is put forward. This can assist the design of new deployable micro air vehicles and bioinspired deployable systems.

    Mitochondrial gene order in Coleoptera has been thought to be conservative but a survey of 60 complete or nearly complete genomes revealed a total of seven different gene rearrangements (deletions, gene order reversals), mainly affecting tRNA genes. All of these were found to be limited to a single taxon or a subclade of Coleoptera. The phylogenetic distribution of a translocation of tRNA(Pro) in three species of elateriform beetles was investigated further by sequencing three nearly complete mitochondrial genomes (Dascillidae, Byrrhidae, Limnichidae) and ten additional individuals for a ∼1370 bp diagnostic fragment spanning the relevant region. Phylogenetic analysis consistently recovered the monophyly of families previously grouped in the contentious superfamily Dryopoidea, a group of approximately 10 beetle families with mainly aquatic lifestyles. The Byrrhidae (moss beetles) were not part of this lineage, although they may be its sister group, to recover the widely accepted Byrrhoidea. The tRNA(Pro) translocation was present in all members of Dryopoidea, but not in any other Elateriformia, providing independent support for this lineage and for a single origin of aquatic habits.

    Massicus raddei (Blessig) is a main wood borer of chestnut tree in China and it attacks the trunk of Quercus mongolica and Quercus liaotungensis in Liaoning and Jilin provinces,Northeast China.It has already caused serious damage to the local economy and forest ecology.In order to explore whether semiochemicals would help the male mate-searching,we devised a bioassay cage to observe the searching and mating behavior of male adults of M.raddei,and to access their visual and olfactory capability from their behavior.The results showed that the blind males could have normal searching and mating behavior.The normal males had no behavioral response to dead females enveloped with paraffin.Both results indicated that vision plays little role on the process of males searching for females.The searching and mating ability of males,with seven segments of antennal flagella removed significantly decreased.Removing whole antennal flagella would deprive the mating capability of males.However,the females who lost the whole antennal flagella could still successfully mate with the normal males.These results suggest that male antennae,especially the terminal seven segments,play important roles in searching and mating behavior of males and may contribute to sensing the semiochemicals released from females.%栗山天牛Massicus radei(Blessig)是中国栎树类树种的主要蛀干害虫,在吉林省和辽宁省主要危害蒙古栎Quercus mongolica和辽东栎Quercus liaotungensis的主干,给当地造成了重大的经济损失和生态灾害.为了明确是否有信息化学物质参与到雄性成虫的配偶搜寻和识别过程中,采用行为观测笼,分别对栗山天牛雄虫的视觉和嗅觉作用进行了研究.结果显示:致盲后的雄虫能进行正常的配偶搜寻和交尾,而且正常的雄虫对只有视觉刺激而无化学刺激的蜡封雌虫尸体毫无反应,说明视觉对雄虫搜寻配偶所起的作用很小.切除7节以上鞭节的雄虫交尾次数大大下降,切除全部9节鞭节的雄虫完全不能实现交尾行为,而切除全部鞭节的雌虫能正常交尾,说明雄虫的触角特别是其端部7节鞭节在识别配偶并成功交尾方面起着重要的作用,并且可能由其感受雌虫所释放的信息化学物质.

Antennal activity variations with time for female and male are also different, and the females show a slow weakening trend, while the activities of males decrease drastically within 0. 8 hours, then exhibit a slowly decreasing trend. Antenna activity of the female is basically lost in vitro for 10 hours and 2.8 hours for the male. Compared with the control, the EAG responses for the females to 12 volatiles are more significant (P0.05). There are significant differences in EAG response between female and male beetles to 11 volatiles (P0.05).

    To study the effects of oviposition secretion on microenvironment of oviposifing incisions in Apriona germari, the influence of oviposition secretion on water content, pH level and microbial quantity was analyzed by artificial inoculation of paper mulberry (Broussonetia papyrifera) trunk caged in the field and imitated incisions. The results showed that the daily water content of the imitated incisions within 4 d after eggs being laid was significantly lower than that of CK ( P < 0. 05 ), while the water content of the imitated incisions beyond 4 d after eggs being laid was higher than that of CK. The diurnal variation of water content in the ovipositing incisions was similar to that of CK. Within 5 d after eggs being laid, the diurnal variation of pH values of the barks with an oviposifing incision and the barks with an imitated incision was similar to that of common barks. Beyond 5 d after eggs being laid, the pH values of the barks with an ovipositing incision and that of the barks with an imitated incision were higher than those of common barks.But there was no obvious difference in pH value between the barks with an ovipositing incision and with an imitated incision at the same day after eggs being laid ( P > 0. 05 ). The bacterial quantity of the barks was compared among imitated incisions, ovipositing incisions and CK. The results showed that at 2 d after eggs being laid, the bacterial quantity of the barks with an imitated incision was significantly (P <0.05 ) higher than that of the barks with an ovipositing incision or that of the common barks. At the day of eggs being laid and at 1, 6, 7, and 8 d after eggs being laid, the bacterial quantity of the barks with an imitated incision was extremely significantly (P <0.01 ) higher than that of the barks with an ovipositing incision or that of the common barks respectively. At 3 d after eggs being laid the bacterial quantity of the common barks (1 320.0 ±189.0) was extremely significantly (P <0.01) higher than that of either the barks with an ovipositing incision or the barks with an imitated incision. At 4 d after eggs being laid, the bacterial quantity of the barks with an imitated incision was higher than that of the barks with an ovipositing incision (P < 0.05 ). There was no significant difference in bacterial quantity between the every two of the three kinds of barks at 5 d after eggs being laid ( P > 0. 05 ). These results suggest that at the prophase of embryonic development, the secretion has the ability of keeping water content of the ovipositing incisions to a certain extent, and does not influence the pH values of the barks containing an ovipositing incision, but the bacterial quantity in the ovipositing incision is inhibited by the secretion.%为探讨桑天牛Apriona germari产卵分泌物对其产卵刻槽微生境的作用,选用构树树干设置野外接虫和人工封槽两种处理,取样测定和分析了桑天牛产卵分泌物对其产卵刻槽微生境含水量、pH值和微生物数量的影响.结果表明:产卵4日内每日的人工封槽刻槽含水量均显著低于对照(P<0.05),4日后均高于对照,产卵刻槽含水量的日变化与对照相似.产卵5日内,人工封槽刻槽和产卵刻槽处树皮的pH值波动与对照基本一致,5日后,二者均高于对照,但同日的人工封槽刻槽与产卵刻槽pH值无明显差异(P>0.05).产卵刻槽、人工封槽刻槽与对照细菌数量比较如下:产卵后第2日人工封槽刻槽显著高于对照和产卵刻槽(P<0.05);新制作与产卵后第1,6,7和8日人工封槽刻槽均达到极显著水平(P<0.01);第3日对照组的细菌数量(1 320.0±189.0)极显著高于人工封槽刻槽和产卵刻槽(P<0.01);第4日人工封槽刻槽显著高于产卵刻槽(P<0.05),但与对照无显著差异(P>0.05);第5日三者差异不显著(P>0.05).分析表明桑天牛产卵分泌物具有维持刻槽微生境含水量稳定的作用,对刻槽处树皮pH值无明显影响,对细菌数量的增加有一定抑制作用.

A total of 89 forms (74 species and 15 subspecies) is recorded from this southwestern country of Africa. Within this assemblage there are 31 endemic forms (33.3%). Some species are represented by only the holotype specimen (some without locality) or the type series. Others were recorded based on a single specimen. Records for six species previously unknow from Angola are given: Foveodromica sp. n. 1, Foveodromica sp. n. 2, Ophryodera rufomarginata bradshawi Péringuey, 1888, Elliptica muata parallelestriata (W. Horn, 1923), Lophyra differens (W. Horn, 1892) and Myriochila jucunda (Péringuey, 1892). A historical review, as well as some considerations on the distribution and conservation status of these beetles in Angola are also presented.

    Full Text Available Alphitobius diaperinus (Panzer (Coleoptera: Tenebrionidae is a pest of stored food products and problematic to every type of poultry production facility. Larvae and adults can ingest and harbor foodborne and poultry pathogens. Determining the efficiency of this insect’s capacity to transmit disease is critical to improving management of A. diaperinus on poultry facilities and providing a safe food supply for human consumption. However, a deficiency exists in the literature reporting measurements of the gut and its defined segments. Previous reports include line drawing depictions, which aid little in the determination of the pathogen reservoir potential of these insects. Advances in technology allowed more accurate visualization and precise measurement of gross anatomical features of the alimentary canal. A photographic depiction to aid the researcher in the visualization of anatomical features and accurate measurements of the alimentary canal for these insects is presented here.

    Full Text Available Massive home invasion by the darkling beetle Mesomorphus villiger Blanchard 1853 (Coleoptera: Tenebrionidae during monsoon season make it a nuisance pest in many regions of south India. Morphology of defensive glands and mode of release and dispersal of the defensive secretion were analysed. Defensive glands were separated from the abdominal sternites by cutting along the posterior margin of the seventh sternite. Glands are evaginations of intersegmental membrane between the seventh and eighth sternites consisting of two long sac-like reservoirs, and glandular secretion is released by exudation and spread through epipleural gutter of elytra. Gradual release of the secretion is a strategy to repel the predators for a longer duration.

    The third instar of Veturius aspina Kuwert, V. assimilis (Weber), V. simillimus Kuwert, V. sinuatocollis Kuwert, V. sinuatus (Eschscholtz), V. crassus (Smith), V. impressus Hincks (as well as pupal stage), V. negroensis Boucher, and the first instar of V. oberthuri (Hincks) (Coleoptera: Passalidae) are described for the first time based on specimens from Argentina, Brazil, and Colombia. The most distinctive characters for these species are the presence and distribution of primary setae and the position, number, and size of the teeth of the metathoracic legs. An evident difference in the number of micro-conical projections on the maxillary stipes and measurements of the pars stridens (mesocoxae) suggests that these characters are useful for species identification. We present an identification key to the species of known larval Veturius (13), representing the 17.6% of total species recognized into genus. Light micrographs and scanning electronic micrographs are included for detailed characters.

    Most wood-feeding insects need an association with microbes to utilize wood as food, and some have special organs to store and convey the microbes. We report here the discovery of the microbe-storage organ (mycangium) in stag beetles (Coleoptera: Lucanidae), which develop in decayed wood. The mycangium, which was discovered in the abdomen, is present in all adult females of 22 lucanid species examined in this study, but absent in adult males. By contrast, adult insects of both sexes of selected Passalidae, Geotrupidae, and Scarabaeidae, which are related to Lucanidae, lacked mycangia similar to those of the lucanid species. Yeast-like microbes were isolated from the mycangium of five lucanid species. DNA sequence analyses indicate that the microbes are closely related to the xylose-fermenting yeasts Pichia stipitis, Pichia segobiensis, or Pichia sp. known from the gut of a passalid species.

    Effects of six pitfall trap preservatives (5% acetic acid solution, distilled water, 70% ethanol, 50% ethylene glycol solution, 50% propylene glycol solution, and 10% saline solution) on collections of carabid beetles (Coleoptera: Carabidae) were studied in a west-central Illinois deciduous forest from May to October 2005. A total of 819 carabids, representing 33 species and 19 genera, were collected. Saline produced significantly fewer captures than did acetic acid, ethanol, ethylene glycol, and propylene glycol, while distilled water produced significantly fewer captures than did acetic acid. Significant associations between numbers of captures and treatment were seen in four species: Amphasia interstitialis (Say), Calathus opaculus LeConte, Chlaenius nemoralis Say, and Cyclotrachelus sodalis (LeConte). Results of this study suggest that type of preservative used can have substantial effects on abundance and species composition of carabids collected in pitfall traps.

    2011-05-01

    Full Text Available This paper summarizes the current knowledge on winter active Carabidae in Central and Northern Europe. In total 73 winter active species are listed, based on literature and own observations. Ground beetles are among the three most numerous Coleoptera families active during the autumn to spring period. The winter community of Carabidae is composed both of larvae (mainly autumn breeding species and adults, as well as of epigeic species and those inhabiting tree trunks. Supranivean fauna is characterized by lower species diversity than the subnivean fauna. The activity of ground beetles decreases in late autumn, is lowest during mid-winter and increases in early spring. Carabidae are noted as an important food source in the diet of insectivorous mammals. They are also predators, hunting small winter active invertebrates.

    The key to an effective pest management program for the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera Buprestidae), is a survey program equipped with tools for detecting and delimiting populations. We studied the effects of trap design, color, and placement on the efficacy of sticky traps for capturing the emerald ash borer. There were significant differences in trap catch along a transect gradient from wooded to open field conditions, with most beetles being caught along the edge, or in open fields, 15-25 m outside an ash (Fraxinus spp. L.) (Oleaceae) woodlot. Greater emerald ash borer catch occurred on purple traps than on red or white traps. Traps placed in the mid-canopy of ash trees (13 m) caught significantly more beetles than those placed at ground level. We also describe a new trap design, a three-sided prism trap, which is relatively easy to assemble and deploy.

    There are direct relationships between the behavioral mechanisms and sensilla. To obtain a better understanding of the behavioral mechanisms in Omosita colon (Linnaeus) (Coleoptera: Nitidulidae), we investigated the types, quantities, and distribution of sensilla on the antenna and mouthparts of O. colon by scanning electron microscopy. The clavate antenna comprised the scape, pedicel, and nine segment flagellomeres and had six types of sensilla, including two subtypes of sensilla chaetica (SC), three subtypes of sensilla basiconica (SB) and sensilla trichodea (ST), and one type of sensilla cavity, sensilla styloconica, and Böhm bristles (BB). The chewing mouthparts of O. colon consist of the labrum, mandible, maxillae, labium, and hypopharynx and had seven types sensilla, including two subtypes of SC and sensilla placodea, seven subtypes of SB, and one type of BB, ST, sensilla coeloconica, and sensilla campaniformia. In this research, we also deduced the relationships between the sensilla on the antenna and mouthparts and their functions.

    We present the first antennal transcriptome sequencing information for the yellow mealworm beetle, Tenebrio molitor (Coleoptera: Tenebrionidae). Analysis of the transcriptome dataset obtained 52,216,616 clean reads, from which 35,363 unigenes were assembled. Of these, 18,820 unigenes showed significant similarity (E-value molitor OBPs and CSPs are closely related to those of T. castaneum. Real-time quantitative PCR assays showed that eight TmolOBP genes were antennae-specific. Of these, TmolOBP5, TmolOBP7 and TmolOBP16 were found to be predominantly expressed in male antennae, while TmolOBP17 was expressed mainly in the legs of males. Several other genes were identified that were neither tissue-specific nor sex-specific. These results establish a firm foundation for future studies of the chemosensory genes in T. molitor.

    Mitochondrial genomes are readily sequenced with recent technology and thus evolutionary lineages can be densely sampled. This permits better phylogenetic estimates and assessment of potential biases resulting from heterogeneity in nucleotide composition and rate of change. We gathered 245 mitochondrial sequences for the Coleoptera representing all 4 suborders, 15 superfamilies of Polyphaga, and altogether 97 families, including 159 newly sequenced full or partial mitogenomes. Compositional heterogeneity greatly affected 3rd codon positions, and to a lesser extent the 1st and 2nd positions, even after RY coding. Heterogeneity also affected the encoded protein sequence, in particular in the nad2, nad4, nad5, and nad6 genes. Credible tree topologies were obtained with the nhPhyML ("nonhomogeneous") algorithm implementing a model for branch-specific equilibrium frequencies. Likelihood searches using RAxML were improved by data partitioning by gene and codon position. Finally, the PhyloBayes software, which allows different substitution processes for amino acid replacement at various sites, produced a tree that best matched known higher level taxa and defined basal relationships in Coleoptera. After rooting with Neuropterida outgroups, suborder relationships were resolved as (Polyphaga (Myxophaga (Archostemata + Adephaga))). The infraorder relationships in Polyphaga were (Scirtiformia (Elateriformia ((Staphyliniformia + Scarabaeiformia) (Bostrichiformia (Cucujiformia))))). Polyphagan superfamilies were recovered as monophyla except Staphylinoidea (paraphyletic for Scarabaeiformia) and Cucujoidea, which can no longer be considered a valid taxon. The study shows that, although compositional heterogeneity is not universal, it cannot be eliminated for some mitochondrial genes, but dense taxon sampling and the use of appropriate Bayesian analyses can still produce robust phylogenetic trees.

    Abstract. The aim of this study was to analyze the occurrence of six groups of insects (Scolytinae, Platypodinae, Bostrichidae, Cerambycidae, Curculionidae and Nitidulidae in a pasture area and forest fragment, in order to provide a discussion that fosters the understanding of the occurrence of these insects in function of the assessed ecosystem, generating data that signal the possibility of bioindication in future work with these organisms. The samples were obtained weekly in Ipiabas, a district of Barra do Pirai, RJ, by the installation of eight impact traps, semifunil model, in the study areas, being four traps in the pasture´s area and four in the forest fragment, respecting the distance of 50 meters between them. Samples were collected from May 2012 to May 2013. A total of 4,796 beetles were collected, of which 3,275 (67.9 % individuals were captured in the forest fragment and 1,521 (32.03% in the pasture. The subfamily Scolytinae was more frequent in the pasture and during the dry season, while the Nitidulidae family showed higher frequency in the forest fragment and in the rainy season. Among the studied groups, the nitidulídeos had greater variation in occurrence’s patterns, indicating that this family has the potential to be used as an indicator of environmental quality.

    Full Text Available The locomotor activity of the beetle Phalerisida maculata Kulzer (Coleoptera Tenebrionidae was studied on the surface of the substrate in two sandy beaches of the Chilean coast: one in north central (ca. 29ºS and the other in south central Chile (ca.39ºS. During the summer period of 1991 the circadian locomotor activity was studied in the southern beach, while during that of 1997 in both beaches. To analyze the activity, pitfall traps were used which were ordered along two transects extended between the upper beach and the resurgence zone. The traps were checked (i.e. collection of captured insects every two hours for a total period of 26 hours. The results showed that the adults of P. maculata were mostly active during the night hours, whereas the larvae were active during both, the day and night. Studies carried out in the beach located in south central Chile show that differences in the tidal range (neap vs. spring tides do not affect the activity patterns. During the locomotor activity, adult and larvae move to lower intertidal levels than those usually occupied while buried. Results of laboratory experiments using actographs under conditions of darkness and constant temperature, suggest that adults and larvae of P. maculata presented a circadian rhythm similar to that observed in the field experiments. It is concluded that P. maculata presents a behaviour that appear to be under control of an endogenous rhythm, without showing differences in the circadian rhythm of activity when beaches located at different latitudes are comparedSe estudió la actividad locomotriz del escarabajo Phalerisida maculata Kulzer (Coleoptera, Tenebrionidae sobre la superficie del sustrato de dos playas arenosas de la costa de Chile: una en el centro norte (ca. 29ºS y otra en el centro sur (ca. 39ºS.

    Full Text Available The efficiency of insecticides against Sitophilus oryzae (Linnaeus, 1763 (Coleoptera, Curculionidae and Rhyzopertha dominica (Fabricius, 1792 (Coleoptera, Bostrichidae was determined exposing them to treated wheat in laboratory. Each plot, which was composed by 1.2 kg of wheat grain, was treated with 5 ml of the concentration/kg of wheat using a propelling air atomizer. Fifteen days after treatment 50 g samples of the grain were taken, from each plot, placed in plastic jars into which 10 adult insects of each species were released. This was repeated every 30 days until 165 days after treatment. The number of dead insects was counted 15 days after each infestation thus the evaluations were made at 30, 60, 90, 120, 150 and 180 days after the insecticide application. Esfenvalerate+fenitrothion+pyperonil butoxide (0,375+7,5+3,0 and 0,5+10,0+4,0 g a.i./t, fenitrothion+esfen-valerate (7,5+0,375 and 10,0+0,375 g a.i./t, fenitrothion+synergised deltamethrin (7,5+0,375 g a.i./t and fenitrothion (7,5 g a.i./t were effective against Sitophilus oryzae until 180 days after treatment. Esfenvalerate+fenitrothion+pyperonil butoxide (0,5+10,0+4,0 g a.i./t, fenitrothion+esfenvalerate (7,5+0,375 and 10,0+0,375 g a.i./t, fenitrothion+synergised deltamethrin (7,5+0,375 g a.i./t were effective against R. dominica until 180 days after treatment. Synergised deltamethrin (0,375 g a.i./t was effective against S. oryzae until 150 days and against R. dominica until 120 days after treatment. Esfenvalerate (0,5 g a.i./t was ineffective against S. oryzae and effective until 60 days after treatment against R. dominica. Fenitrothion (7,5 g a.i./t was ineffective against R. dominica. The use of mixtures of organophosphorus plus pyrethroids were more effective against S. oryzae and R. dominica when compared with these insecticides used alone.

    Full Text Available The aim of the study was to identify the seasonal changes in the number of saproxylic beetles connected with birch in the Kampinos National Park. The research was conducted for 12 consecutive months in research areas representing 10 different site types. The beetles were collected from wood using photoeclectors. The largest number of species was collected in April and the lowest in January. An increase in number occurred during spring and summer months for species associated only with rotting wood, fructifications of tree fungi, the subcortical environment and hollows. In the same period the number of species not associated or potentially associated with decaying trees and wood decreased. During winter months, the differences in the number of trapped specimens were the smallest. The proportion of zoophagous species amongst the collected specimen increased in autumn and winter. The share of saprophagous species was the highest during the summer-autumn period and the share of mycetophages (jointly with myxomycophages was the highest during spring and summer. We distinguished two separate groups of Coleoptera with the first one (‘summer group’ including species trapped during late-spring and summer months, while the second one (‘winter group’ includes species found in autumn, winter and early-spring months. In the ‘summer group’, an average of 55.8 species was trapped each month with 331.2 specimen of Coleoptera, while in the ʻwinter group’ an average of 56.1 species with 228.4 Coleoptera specimen were caught.

  18. Coleoptera and microbe biomass in Antarctic Dry Valley paleosols adjacent to the Inland Ice: Implications for Mars

    Bulk paleosol samples collected from a Middle to Early Miocene moraine in the New Mountain area of the Dry Valleys, Antarctica, yielded Coleoptera exoskeletons and occasional endoskeletons showing considerable diagenetic effects along with several species of bacteria, all lodged in a dry-frozen but salt-rich horizon at shallow depth to the land surface. The till is at the older end of a chronologic sequence of glacial deposits, thought to have been deposited before the transition from wet-based to cold-based ice (∼15 Ma), and hence, entirely weathered in contact with the subaerial atmosphere. It is possible, though not absolutely verifiable, that the skeletons date from this early stage of emplacement having undergone modifications whenever light snowmelt occurred or salt concentrations lowered the freezing temperature to maintain water as liquid. Correlation of the Coleoptera species with cultured bacteria in the sample and the likelihood of co-habitation with Beauveria bassiani found in two adjacent, although younger paleosols, leads to new questions about the antiquity of the Coleoptera and the source of N and glucose from chitinase derived from the insects. The skeletons in the 831 section may date close to the oldest preserved chitin (Oligocene) yet found on Earth. While harsh Martian conditions make it seemingly intolerable for complex, multicellular organisms such as insects to exist in the near-surface and subaerially, life within similar cold, dry paleosol microenvironments (Cryosols) of Antarctica point to life potential for the Red Planet, especially when considering the relatively diverse microbe (bacteria and fungi) population.

    The complete mitochondrial genome of the recently discovered beetle family Iberobaeniidae is described and compared with known coleopteran mitogenomes. The mitochondrial sequence was obtained by shotgun metagenomic sequencing using the Illumina Miseq technology and resulted in an average coverage of 130 × and a minimum coverage of 35×. The mitochondrial genome of Iberobaeniidae includes 13 protein-coding genes, 2 rRNAs, 22 tRNAs genes, and 1 putative control region, and showed a unique rearrangement of protein-coding genes. This is the first rearrangement affecting the relative position of protein-coding and ribosomal genes reported for the order Coleoptera.
