    Estudou-se a abundância relativa das espécies da família Cerambycidae (Insecta-Coleoptera em um pomar de frutíferas misto composto por 28 diferentes espécies, no período de dezembro de 1997 a maio de 1999 em Ceres, Estado de Goiás, Brasil. Foram utilizadas armadilhas luminosas modelo “Luiz de Queiroz” com lâmpadas Bl-15 wats. Essas armadilhas foram ligadas por 12 horas em dois dias consectivos num total de 24 horas de coletas semanais. Coletaram-se 1.474 cerambicídeos, agrupados em 39 gêneros e 49 espécies. Acanthoderes jaspidea, Achryson surinamum, Chlorida festiva, Eurodacrys sexgutatta, Gnomibidion fulvipes, Lophopoeum timbouve, Megacyllene acuta, Rhopalophora collaris e Trichophorus distinctus foram as espécies classificadas como muito abundantes. Das espécies coletadas, 48,98 % foram classificadas como raras, 12,24 % como dispersas, 20,41 % como comuns e 18,37 % como muito abundantes. Dentre os 39 gêneros, Oreodera foi representado por três espécies (6,13 %, os gêneros Acanthoderes, Aerenica, Chrysoprasis, Colobothea, Eutrypanus, Megacylene, Myoxomorpha e Nyssodrysternum por duas espécies (4,08 %, e os demais gêneros por apenas uma espécie.

    The complete mitochondrial genome of Eucryptorrhynchus brandti (Harold) (Insecta: Coleoptera: Curculionidae) were reconstructed from whole-genome Illumina Hiseq 2000 sequencing data with an average coverage of 1406.7X. The circular genome is 15,122 bp in length, consisting of 13 protein-coding genes (PCGs), 21 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs) and one D-loop or control region. The tRNA-Ile gene was not found in the mitochondrial genome, as is identical to two other curculionidae species, i.e. Sphenophorus sp. (GU176342) and Naupactus xanthographus (GU176345). All PCGs initiated with ATN codons, except for the ND1 started with TTG. Two PCGs (COI and ND4) have an incomplete stop codon T. Two PCGs (ND4L and ND1) harbor the stop codon TAG, while all other PCGs terminated with the TAA codon. The nucleotide composition is highly asymmetric (38.7% A, 14.4% C, 9.2% G and 37.8% T) with an overall AT content of 76.5%. PMID:25427809

    The fertility of the Japanese pine sawyer beetle Monochamus alternatus (Coleoptera: Cerambycidae) irradiated with 60Co γ-rays was remarkable reduced at the doses of 30Gy, 35Gy and 40Gy, especially at 40Gy. When the non-irradiated females were coupled with the irradiated males first, and then coupled with non-irradiated males, the hatchability and the fertility had little higher but lower than the control. It explained that radiation has certain influence to the female gonad. It also has difference between the hatching rate and the amount of eggs in different match. (authors)

  6. Displacement of Tetropium cinnamopterum (Coleoptera: Cerambycidae) by Its Invasive Congener Tetropium fuscum.

    We examined the native community of insects interacting with an invasive species, Tetropium fuscum (F.) (Coleoptera: Cerambycidae), in its new range to explore reasons for the invader's relatively slow spread. Tetropium fuscum is a European spruce borer established in Nova Scotia since at least 1990, but it has spread only about 125 km from its site of introduction. We compared the densities of Tetropium spp., their known parasitoids, and the community of wood-boring insects at sites located within the invasion zone in Nova Scotia versus well outside this zone, in New Brunswick, Canada. Using red spruce trees stressed by girdling or felling, we tested whether: 1) T. fuscum had altered the native wood-boring community; 2) T. fuscum displaced a native congener, Tetropium cinnamopterum (Kirby); and 3) parasitism rates of Tetropium spp. differed between the invaded and noninvaded zones. Both Tetropium spp. and their parasitoid wasps emerged exclusively from felled trees as opposed to girdled trees. We found no difference in community diversity inside versus outside the invasion zone. The combined densities of both Tetropium spp. and their overall parasitism rates also did not differ between zones, but T. cinnamopterum density was significantly greater outside the invasion zone, suggesting T. fuscum may displace the native congener where they are sympatric. Our results suggest that the native and invasive Tetropium spp. act as a single functional species in the invasion zone. We speculate that natural control agents (predators, parasitoids, and competitors) might be limiting the rate of spread of T. fuscum. PMID:27247305

    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.

    Full Text Available Here we consider 274 alien Coleoptera species belonging to 41 of the 137 beetle families in Europe (Cerambycidae, Curculionidae sensu lato, Chrysomelidae sensu lato and Coccinelidae are treated separately elsewhere. Among the families we consider asinvaded the European fauna, Acanthocnemidae and Ptilodactylidae represent new arrivals. Many species-rich families have surprisingly few aliens, whereas some relatively minor families such as Dermestidae, Nitidulidae and Anobiidae have a relatively high representation of alien species. Since the start of the 19th century, the number of coleopteran aliens introduced into Europe has continued to increase. Alien species colonizing Europe derive from a wide range of geographic regions as well as ecozones, but the most important source area is Asia. The countries with the largest number of alien species established are France, Germany and Italy. The majority have been introduced accidentally via international transport mechanisms. The most important route for importation is stored products and crops, followed by transport of wood, then horticultural and ornamental plants. Most alien species in these families are found within anthropogenic habitats in Europe. The introduction of invasive alien beetles in these families has had significant economic impacts, particularly as pests of stored foodstuffs, as well as serious ecological impacts. For example, the buprestid species Agrilus planipennis, recently recorded in Russia, is an important potential economic threat which may also impact the biodiversity associated with ash trees.

    The whitespotted sawyer, Monochamus scutellatus scutellatus (Say) (Coleoptera: Ce-rambycidae), is one of the most damaging wood-boring insects in recently burned boreal forests of North America. In Canada, salvage logging after wildfire contributes to maintaining the timber volume required by the forest industry, but larvae of this insect cause significant damage that reduces the economic value of lumber products. This study aimed to estimate damage progression as a function of temperature in recently burned black spruce (Picea mariana (Miller) Britton, Sterns, and Poggenburg) and jack pine (Pinus banksiana Lambert) trees. Using axial tomographic technology, we modeled subcortical development and gallery depth progression rates as functions of temperature for both tree species. Generally, these rates were slightly faster in black spruce than in jack pine logs. Eggs laid on logs kept at 12 degrees C did not hatch or larvae were unable to establish themselves under the bark because no larval development was observed. At 16 degrees C, larvae stayed under the bark for > 200 d before penetrating into the sapwood. At 20 degrees C, half of the larvae entered the sapwood after 30-50 d, but gallery depth progression stopped for approximately 70 d, suggesting that larvae went into diapause. The other half of the larvae entered the sapwood only after 100-200 d. At 24 and 28 degrees C, larvae entered the sapwood after 26-27 and 21 d, respectively. At 28 degrees C, gallery depth progressed at a rate of 1.44 mm/d. Temperature threshold for subcortical development was slightly lower in black spruce (12.9 degrees C) than in jack pine (14.6 degrees C) and it was 1 degrees C warmer for gallery depth progression for both tree species. These results indicate that significant damage may occur within a few months after fire during warm summers, particularly in black spruce, which highlights the importance of beginning postfire salvage logging as soon as possible to reduce economic

    Abstract. The study of the insects associated with branches and stems girdled by Oncideres saga (Dalman is important to know its possible natural enemies. Therefore, these work had the objective of register the insects associated with branches and stems girdled of Acacia mangium Willd. by this twig girdler beetle, in Coimbra, state of Minas Gerais, Brazil. Stems and branches of A. mangium were collected in January/2007 to April/2007. This material has been inspected, stored in plastic bags, and kept in a room with controlled conditions (25.4 ± 0.3°C and 66.7 ± 1.4%. It was noted the presence of a non-determined species of Scolytidae and the emergence of four species of Cerambycidae: Engyum quadrinotatum Thomsom; Eburodacrys sexmaculata (Olivier; Achryson surinamum (Linnaeus and Neoclytus pusillus (Laporte & Gory. It can be concluded that studies are needed with the objective of verify the behavior of these insects in relation with twig girdler O. saga.

Os dados foram obtidos a partir de coletas através de armadilha malaise no estrato do sub-bosque de cinco áreas com diferentes graus de intervenção antrópica, de setembro de 1999 a agosto de 2000. As 52 semanas de amostragem nas cinco áreas resultaram na coleta de 10.822 indivíduos de 1659 espécies. Todas as áreas apresentaram alta riqueza de espécies e diversidade, como indicado por vários índices. A área em estágio mais avançado de sucessão vegetal foi menos rica do que aquelas em estágio inicial/intermediária. De acordo com diferentes estimadores de riqueza de espécies, o número de espécies coletadas poderia aumentar de 22-123% com o aumento do esforço de coleta. As áreas menos conservadas foram mais ricas em espécies raras ("singletons", "doubletons" e únicas do que as mais conservadas. Nas cinco áreas houve uma constância taxonômica entre as famílias mais ricas (Curculionidae, Chrysomelidae, Cerambycidae, Staphylinidae, Mordelidae, Elateridae, Scarabaeidae, Coccinellidae e Tenebrionidae envolvendo 60% do total de espécies, como observado para a abundância de indivíduos. A existência de um padrão de constância taxonômica de famílias, quando considerados 60% da riqueza de espécies e/ou de abundância de indivíduos por local, poderá tornar mais fácil e rápido o estudo de comunidades de Coleoptera, habilitando a ordem a ser um táxon indicador de condições ambientais de áreas florestadas.The species richness, taxonomic composition, rare species, and taxonomic constancy at family level were studied in communities of Coleoptera in Vila Velha, Ponta Grossa, Paraná, as part of PROVIVE project.

    Complete mitochondrial genomes for two corn rootworm species, Diabrotica virgifera virgifera (16,747 bp) and Diabrotica barberi (16,632; Insecta: Coleoptera: Chrysomelidae), were assembled from Illumina HiSeq2000 read data. Annotation indicated that the order and orientation of 13 protein coding genes (PCGs), and 22 tRNA and 2 rRNA sequences were in typical of insect mitochondrial genomes. Non-standard nad4 and cox3 stop codons were composed of single T nucleotides and likely completed by adenylation, and atypical TTT start codons was predicted for both D. v. virgifera and D. barberinad1 genes. The D. v. virgifera and D. barberi haplotypes showed 819 variable nucleotide positions within PCG regions (7.36% divergence), which suggest that speciation may have occurred ~3.68 million years ago assuming a linear rate of short-term substitution. Phylogenetic analyses of Coleopteran MtD genome show clustering based on family level, and may have the capacity to resolve the evolutionary history within this Order of insects. PMID:24657060

    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.

    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.

    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

    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. PMID:26911160

    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...

    The oak longhorn beetle, Massicus raddei ( Blessig) ( Coleoptera; Cerambyeidae) is an important wood borer pest in natural oak forests (Quercus spp. ) in northeastern China. This beetle takes 3 years to complete one generation and is difficult to be controlled due to a highly concealed life history in its larval and pupal stages. Determination of larval instar number and duration is the important foundation for the insect pest forecasting and the scientific management. The number of larval instars was determined using statistical method of frequency analysis through sampling periodically by dissecting infestation trees at Kuandian County, Liaoning Province during 2008 -2011, during which the oak longhorn beetle larvae at different developmental stages in forests were collected and five morphological variables of the longhorn beetle larvae, including length of mandible, distance between main ocelli, width of the prothoracic plate, length of the mesothoracic spiracle, and body length, were measured under binocular microscope with an eyepiece micrometer. The results showed that the larvae of oak longhorn beetle have 6 instars without difference between male and female. The three variables including mandible length, distance between main ocelli and width of the prothoracic plate can be used for the separation of larval instars as the sclerotized structures, while length of the mesothoracic spiracle and body length were not reliable due to high variation. The average duration of 1 - 6 instars measured by the method of median population stadia in fields were9.25, 266. 85, 48.09, 51.29, 260.33 and 385.71 d, respectively. The total larval stage duration was over 1 021. 52 d in fields. In northeastern China, the occurrence of oak longhorn beetle was very uniform and the development of population was highly synchronous in natural conditions. The larvae of the oak longhom beetle need to undergo 3 winters to complete one generation. In the first year larvae overwinter as 2nd

    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

  1. Metabolic Profiling of Somatic Tissues from Monochamus alternatus (Coleoptera: Cerambycidae Reveals Effects of Irradiation on Metabolism

    Full Text Available A high-level of sexual sterility is of importance for the sterile insect technique (SIT. However, the use of high-dose-intensity gamma radiation to induce sterility has negative impacts not only on reproductive cells but also on somatic cells. In this study, we investigated the metabolite differences in somatic tissues between non-irradiated, 20-Gy-irradiated, and 40-Gy-irradiated male Monochamus alternatus, an important vector of the pathogenic nematode, Bursaphelenchus xylophilus, which kills Asian pines. The results showed that metabolite levels changed moderately in the 20-Gy samples but were markedly altered in the 40-Gy samples compared with the non-irradiated samples. Twenty-six and 53 metabolites were disturbed by 20-Gy and 40-Gy radiation, respectively. Thirty-six metabolites were found to be markedly altered in the 40-Gy samples but were not changed significantly in the 20-Gy samples. The comprehensive metabolomic disorders induced by 40-Gy radiation dysregulated six metabolic pathways involved in the life process. The findings presented in this manuscript will contribute to our knowledge of the characteristic metabolic changes associated with gamma-radiation-induced damage to somatic cells and will allow for better exploration of the SIT for the control of this target pest.

    Aeolesthes oenochrous (Fairmaire), a large and colorful longhorn beetle, is an endangered species in Taiwan. Its complete mitogenome, 15,747 bp, shows a typical coleopteran organization, containing 13 protein coding genes, 22 tRNA genes, 2 rRNA genes and one A + T rich region. Two protein coding genes, i.e. COI and ND1, have the atypical start codon of AAT and TTG, respectively. The third nucleotide position of codons shows extremely low guanine content. In the A + T rich region, there were two poly-T stretches with 14 and 13 thymine each. These two poly-T stretches were clarified by the cloning method. PMID:24810074

  20. Midgut and fat body bacteriocytes in neotropical cerambycid beetles (Coleoptera: Cerambycidae).

    Science.gov (United States)

    Calderon, Olga; Berkov, Amy

    2012-02-01

    Xylophagous insects derive nutrients from intractable substrates by producing or ingesting cellulolytic enzymes, or by maintaining associations with symbiotic microbes. Wood-boring cerambycid beetle larvae sometimes house maternally-transmitted endosymbiotic yeasts that are presumed to provide their hosts with nutritional benefits. These are thought to be absent from species in the large subfamily Lamiinae; nevertheless yeasts have been repeatedly isolated from the guts of neotropical lamiines. The objective of this study was to conduct transmission electron microscopy (TEM) studies of cerambycid larval midgut tissues to determine if gut yeasts were intracellular, or simply present in the gut lumen. Nine cerambycid larvae were harvested from two trees in the Brazil nut family (Lecythidaceae) in the rain forest of SE Peru; seven were identified using mtDNA sequence data and processed for TEM. Yeasts cultured from larval frass or exuvia, and identified with rDNA sequence data, were identical or similar to yeasts previously isolated from beetles. In TEM analyses yeast cells were found only in the gut lumens, sometimes associated with fragments of thick-walled xylem cells. Apparent bacteriocytes were found in either midgut or fat body tissue of three larval specimens, including two lamiines. This is the first report of a potential fat body symbiosis in a cerambycid beetle. Future studies of cerambycid symbiosis should distinguish the identities and potential roles of free-living organisms in the gut lumen from those of organisms harbored within gut epithelial or fat body tissue.

    The old house borer has been present in the u.s. for over 200 years. During this time limited biological studies have been conducted. The biological data contained in these studies are based on casual field observations and reports from Europe and South Africa. The data presented here represent the first attempt in the U.S. to colonize and study the ORB under field and laboratory conditions. It is evident from this research that the ORB exhibits an extreme amount of biological plasticity. ...

  2. Evidence for a female-produced, long range pheromone of Anoplophora glabripennis (Coleoptera: Cerambycidae)

    Institute of Scientific and Technical Information of China (English)

    Jacob D.Wickham; Zhichun Xu; Stephen A.Teale

    2012-01-01

    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.

  4. Adult Diapause in Coleoptera

    Directory of Open Access Journals (Sweden)

    Ivo Hodek

    2012-01-01

    Full Text Available Recent studies dealing with adult (reproductive diapause in the Coleoptera are reviewed, as a kind of supplement to the classic compendia. In the first two sections, the general characteristics of adult diapause are described and principal terms explained. Original articles dealing with 19 species from nine coleopteran families (Coccinellidae, Chrysomelidae, Bruchidae, Curculionidae, Carabidae, Silphidae, Scolytidae, Scarabaeidae, and Endomychidae are reviewed. Finally attempts are made at generalisations from the papers reviewed, and hypotheses on diapause evolution are inferred. A polyphenic character of diapause is a prominent feature in C. septempunctata and L. decemlineata, but has been found also in other Coleoptera and in insects generally and often generates voltinism heterogeneity within populations.

    In north-central Georgia, 13 species of woodboring beetles (Coleoptera: Cerambycidae: Cerambycinae) were attracted to multiple-funnel traps baited with ethanol and one of the following pheromones: (1) racemic 3-hydroxyhexan-2-one; (2) racemic 3-hydroxyoctan-2-one; and (3) syn-2,3-hexanediol. The following species were attracted to traps baited with ethanol and 3-hydroxyhexan-2-one: Anelaphus pumilus (Newman), Eburia quadrigeminata (Say), Euderces pini (Olivier), Knulliana cincta (Drury), Neoclytus mucronatus (F.), Neoclytus scutellaris (Olivier), and Xylotrechus colonus (F.). Clytus marginicollis Castelnau & Gory, and Anelaphus parallelus (Newman) were attracted to traps baited with ethanol and 3-hydroxyoctan-2-one, whereas traps baited with ethanol and syn-2,3-hexanediol were attractive to Anelaphus villosus (F.), A. parallelus, Neoclytus acuminatus (F.), Neoclytus jouteli jouteli Davis, and Megacyllene caryae (Gahan). Ethanol enhanced catches of seven cerambycid species in traps baited with syn-2,3-hexanediol and 3,2-hydroxyketones. Catches of bark and ambrosia beetles (Curculionidae: Scolytinae) in ethanol-baited traps were largely unaffected by the addition of syn-2,3-hexanediol and 3,2-hydroxyketone lures, except for two species. The mean catches of Hypothenemus rotundicollis Wood & Bright and Dryoxylon onoharaensum (Murayama) in ethanol-baited traps increased and decreased, respectively, with the addition of racemic 3-hydroxyoctan-2-one. Traps baited with ethanol and syn-2,3-hexanediol were attractive to Xylobiops basilaris (Say) (Bostrichidae) and Chariessa pilosa (Forster) (Cleridae), whereas Temnoscheila virescens (F.) (Trogossitidae) were attracted to traps baited with ethanol and 3-hydroxyhexan-2-one. The assassin bug, Apiomerus crassipes (F.) (Hemiptera: Reduviidae), was attracted to traps baited with ethanol and 3,2-hydroxyketones. PMID:26453724

    Abstract Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, Oobius agrili Zhang & Huang and Oobius longoi (Siscaro), were introduced into North America for classical biocontrol and have successfully established. Two new native North American species that parasitize eggs of Agrilus spp. (Buprestidae) are described and illustrated from the USA: Oobius minusculus Triapitsyn & Petrice, sp. n. (Michigan), an egg parasitoid of both Agrilus subcinctus Gory on ash (Fraxinus spp.) and Agrilus egenus Gory on black locust (Robinia pseudoacacia L.) trees, and Oobius whiteorum Triapitsyn, sp. n.

    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.

    A preferência para oviposição e/ou alimentação de Macropophora accentifer foi observada em pomar misto abandonado, formado por tangerinas-cravo e rio, laranjas baianinha e natal, tangor-sabará e limão-cravo em plantas de 5 a 20 anos de idade e plantado no espaçamento de 10m. As fêmeas da espécie foram marcadas com tintas na região do pronoto. As coletas foram manuais, as marcações, liberações e recapturas foram realizadas de setembro a novembro e de março a maio. As fêmeas, num total de 231, coletadas em cada uma das seis variedades, foram marcadas e imediatamente liberadas em todas as outras variedades, inclusive na mesma variedade onde foi coletada. As recapturas foram realizadas dez dias após cada liberação. Foram realizadas 30 liberações e 50 recapturas. A preferência foi determinada levando-se em consideração o número de fêmeas que permaneceram, retornaram ou migraram para cada variedade de citros. Observou-se que 2,16% retornaram para a variedade onde foram coletadas, 59,31% permaneceram na variedade onde foram liberadas, 30,74% migraram para outras variedades e 7,79% não foram recapturadas. Concluiu-se que a tangerina-cravo apresentou 46,75% de preferência, seguida da tangor-sabará com 16,88%, baianinha com 10,82%, natal com 9,95% e tangerina-rio com 7,8%.

    The preference for oviposition and/or alimentation was observed in Macropophora accentifer females in a mixed yard, composed by cravo and rio tangerines, baianinha and natal oranges, tangor sabará and cravo lemon. The plants were 5 to 20 years old, and the yard was abandoned and cultivated with a distance of 10m between plants. The females were labeled with dye ink in the pronotum region. Manual collection, labeling, release and recapture were carried out in September/October/November, and in March/April/May. A total of 231 females insects were collected in each variety, labeled and immediately released in different varieties, including those who collected firstly. The recaptures were carried out twelve days after each release; 30 releases and 50 recaptures were performed. The preference was determined considering the number of female insects that remained, returned or migrated to each one of the citrus varieties. It was observed that 2.16% of the females returned to the varieties where they were previously collected, 59.31% remained in the variety where they were released, 30.74% migrated to different varieties, and 7.79% were not recaptured. The cravo tangerine presented 46.75% of preference, followed by tangor sabará with 16.88%, baianinha orange with 10.82%, natal orange with 9.95% and rio tangerine with 7.8%.

    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.

    The response of antennal olfactory receptor neurons (ORNs) of Monochamus galloprovincialis to several odourants was tested using single sensillum electrophysiology. Behaviourally active pheromone, and kairomone (host and sympatric bark beetle pheromone) odours were tested alongside smoke compounds released by burnt wood that are potentially attractive to the insect. The antennae bore several types of sensilla. Two plate areas in the proximal and distal ends of each antennal segment were covered with basiconic sensilla that responded to the odour stimuli. Sensilla basiconica contained one or two cells of different spike amplitude. The 32 male and 38 female ORNs tested responded with excitations or inhibitions to the different plant odours. In general the response of male and female receptors was very similar so they were pooled to perform a cluster analysis on ORN responses. Six ORNs were clearly specialised for pheromone reception. Responses to kairomone and smoke odours were less specific than those of pheromone, but a group of 9 cells was clearly excited by smoke compounds (mainly eugenol and 4-methyl 2-methoxyphenol), a group of 8 cells was very responsive to α-pinene, β-pinene and cis-verbenol, and a group of 14 cells responded to a wider range of compounds. The rest of the cells (47%) were either non-responsive or slightly inhibited by smoke compounds. Dose-response curves were obtained for several compounds. Different compounds induced significantly different latencies and these appeared to be unrelated to their boiling point. PMID:26296453

    The cashew stem girdler, Analeptes trifasciata, is a major insect pest of cashew in Nigeria causing economic damage in cashew plantations even at low density. In this study, newly emerged adults of A. trifasciata reared from field-infested cashew stems were collected from the rearing cages, sexed, and dissected to reveal the internal structures of the insects. The gut was excised and separated into the foregut, midgut, and hindgut. The dissected gut compartments were blotted dry by sandwiching in sterile Whatman No. 1 (150 mm) filter paper for a minute. The inoculated gut parts showed the presence of eight fungi flora, namely, Aspergillus repens, Trichoderma spp., Fusarium verticillioides, Lasiodiplodia theobromae, yeast, Aspergillus niger, Fusarium spp., and Rhizopus stolonifer. The frequencies of occurrence of bacteria in the gut compartments of A. trifasciata were Enterobacter spp.: 83.33%; Escherichia coli and Streptococcus spp.: 55.56% each; Staphylococcus spp.: 44.44%; Klebsiella pneumonia: 50% and Salmonella shigella: 11.11%, while each of Serratia marceascea, Pseudomonas spp., and Micrococcus lutea had 5.56% occurrence. The occurrence of mycoflora and microbiota species varied in the gut compartments of A. trifasciata, indicating the role of these microorganisms in metabolic and other bioprocesses of A. trifasciata during digestion and synthesis of complex food substances from the cashew stem substrate. This study would provide basic information for enzymatic studies of A. trifasciata with a view to developing an integrated pest management (IPM) protocol for managing the pest in cashew plantations.

    The Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), is a polyphagous wood-boring insect native to Asia. Since it invaded North America in the 1990s, the beetle has been continuously targeted by quarantines and eradication programs in the United States and Canada. We examined the potential for development of new species-associations between A. glabripennis and hymenopteran parasitoids collected from cerambycids and other wood-boring insects infesting red maple (Acer rubrum L.) trees in the mid-Atlantic region of the United States. Results of our study showed that five groups of braconid parasitoids (Ontsira mellipes Ashmead, Rhoptrocentrus piceus Marsh, Spathius laflammei Provancher, Heterospilus spp., and Atanycolus spp.) successfully attacked early instars of A. glabripennis larvae infesting red maple logs and produced both male and female progenies. One species, O. mellipes, was continuously reared on A. glabripennis larvae inserted inside small red maple sticks for over 50 generations, and produced female-biased progeny (∼6:1 female to male ratio) at each generation. Continuous rearing of O. mellipes on A. glabripennis larvae did not significantly increase the parasitism and mean number of progeny produced per parasitized host. Together, these findings demonstrate that some North American parasitoids may be able to develop new associations with A. glabripennis and thus should be further studied under semifield or field conditions for possible use in biocontrol.

    Tree colonization and feeding activity of the invasive wood-borer Asian longhorn beetle (Anoplophora glabripennis), an Asian pest introduced into North America and Europe, was studied in a newly invaded area in Italy. The hypothesis being tested was that the reproductive success of the insect depend on habitat type and tree suitability. Adult beetles were caged on branches of host and nonhost species, in both urban and forest habitats. Two months later, number and size of feeding patches on plant tissues, eggs laid, and surviving larvae were assessed. Bark concentration of C and N was also measured from the same trees. Results indicated that the mean area of plant tissues consumed by adult feeding was significantly larger on trees growing in forest than in urban habitat, although within the same habitat there were no differences between susceptible and nonsusceptible trees. ALB tree colonization, in terms of number of eggs laid and young larvae survival, was not affected by habitat while it was higher on susceptible trees. Although trees growing in forests had a lower nitrogen concentration, they allowed colonization rates similar to those of trees growing in the urban habitat. Hence, the amount of carbon and nitrogen did not fully explain tree suitability or habitat selection. We suggest compensatory feeding as a potential mechanism that might explain this peculiar situation, as supported by a more intensive feeding activity recorded on trees in the forest. Suitability of different trees may be due to other factors, such as secondary chemical compounds. PMID:25424840

    The blister beetle is an important resource insect due to its defensive substance cantharidin, which was widely used in pharmacology and plant protection. We determined the complete mitochondrial genome of Epicauta chinensis Laporte (Coleoptera: Tenebrionoidae: Meloidae). The circular genome is 15,717 bp long, encoding 13 protein-coding genes (PCGs), two ribosomal RNAs and 22 tRNAs and containing a A+T-rich region with gene arrangement identical to other Coleopteran species. Twelve PCGs start with typical ATN codon, while ATP8 gene initiate with GTT for first report in Insecta. All PCGs terminate with conventional stop codon TAA or TAG. All tRNAs in E. chinensis are predicted to fold into typical cloverleaf secondary structure, except tRNA-Ser(AGN), in which the dihydrouracil arm (DHU arm) could not form stable stem-loop structure. The secondary structure of lrRNA and srRNA comprises 48 helices and 32 helices respectively. The 1101 bp A+T-rich region contains a 15 bp poly-T stretch and microsatellite-like repeats rather than large tandem repetitive sequences. Phylogenetic analysis, based on 13 PCGs of 45 Coleopteran species, show that E. chinensis grouped with Tenebrionidae species. It also support the topology of (((Chrysomelidae+Curculionoidea)+(Cucujoidea+Cleroidea))+Tenebrionoidea) within Cucujiformia. PMID:26707213

    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. PMID:22812119

O estudo foi realizado nas proximidades da vila de Alter do Chão (2º 31' S e 55º 00' W, localizada a aproximadamente 36 km a sudoeste de Santarém, Pará, Brasil. Vinte e duas áreas de savanas de 3,75 ha (250 x 150 m distribuídas em 30.000 ha foram amostradas, no período de 21 de julho a 13 de agosto de 2003, utilizando 66 armadilhas de queda com três tipos de iscas (fezes bovinas, fezes humanas e carcaças. Foram encontrados indivíduos de D. gazella em quatro das vinte e duas áreas amostradas. Procurou-se explicar a presença da espécie nas áreas de savana através de análises de regressão logística, onde as variáveis explicativas foram: ocorrência de queimada nos últimos seis anos, diversidade e abundância total de Scarabaeidae nativos presentes na área, abundância de Canthon sp.1, (espécie de Scarabaeidae mais abundante na região. Exceto pela abundância total de indivíduos de Scarabaeidae nativos, nenhuma das variáveis bióticas e abióticas tiveram efeito estatisticamente significativo na presença do D. gazella.

The research was carried out near Alter do Chão village (2º 31' S; 55º 00' W, 36 Km Southwest of Santarém, Pará, Brazil. Twenty two areas were sampled, from 21 July to 13 August 2003, using 66 baited pitfall traps (cattle dung, human faeces and carcass bait. D. gazella individuals were found in four of twenty two sampled areas. The presence of the species in the savanna was analysed by a logistic regression, using the occurrence of burnings in the last six years, species richness and abundance of native Scarabaeinae, and abundance of Canthon sp1, (the most abundant species in the region, as explanatory variables. Except for the total abundance of native Scarabaeinae, none of the variables were statistically significant for the presence of D. gazella. Hypothetically, these results were probably due to a non-analysed factor related to the invasibility of the area by D. gazella, or lack of time for the species to disperse and establish in all the areas, or a resistance of native dung beetle community to D. gazella invasion. Nevertheless, there must be a competitive mechanism of invasion resistance bounding the abundance of native species and D. gazella invasibility.

    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 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.

    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.

    Aim of this study was to investigate relationships between the red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) and the entomopathogenic nematode Steinernema carpocapsae (EPN); particularly, the work was focused on the immune response of the insect host in naive larvae and after infection with the EPN. Two main immunological processes have been addressed: the activity and modulation of host prophenoloxidase-phenoloxidase (proPO) system, involved in melanization of not-self and hemocytes recognition processes responsible for not-self encapsulation. Moreover, immune depressive and immune evasive strategies of the parasite have been investigated. Our results suggest that RPW possess an efficient immune system, however in the early phase of infection, S. carpocapsae induces a strong inhibition of the host proPO system. In addition, host cell-mediated mechanisms of encapsulation, are completely avoided by the parasite, the elusive strategies of S. carpocapsae seem to be related to the structure of its body-surface, since induced alterations of the parasite cuticle resulted in the loss of its mimetic properties. S. carpocapsae before the release of its symbiotic bacteria, depress and elude RPW immune defenses, with the aim to arrange a favorable environment for its bacteria responsible of the septicemic death of the insect target.

    2001-01-01

    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.

    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.

    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.

    Abstract 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. PMID:27006596

    为弄清天牛的核型特征,补充我国天牛染色体分类特征和天牛细胞分类学的基础研究空缺,本文以4种沟胫天牛亚科天牛为研究对象,选取天牛的分裂旺盛组织精巢(卵巢)和中肠,在不同的条件下进行天牛染色体玻片的制备和观察.结果显示:4种天牛染色体数目均为2n=20,性别决定机制为Xyp.其中,云斑白条天牛Batocera lineolata的核型公式:4L +5M+ Xyp,大型染色体4对,中型染色体5对,性染色体为小型;榉白背粉天牛Olenecamptus cretaceus marginatus、中华八星粉天牛Olenecamptus octopustulatus chinensis(粉天牛属)和桑天牛Apriona germari的核型公式均为:5L +4M+ Xyp,大型染色体5对,中型染色体4对,性染色体为中型.粉天牛属的榉白背粉天牛和中华八星粉天牛的核型指数非常相近;桑天牛的染色体公式虽然与粉天牛属相同,但长度和着丝粒位置明显不同.%To make clear the characteristics of karyotypes of long-horned beetles, supplement the chromosome classification feature and fill up the basic research vacancy of cytotaxonomy about long-horned beetles, the tissues with exuberant differentiation (testis, ovary and midgut) of four species of Lamiinae beetles were chosen for preparing slides of chromosomes under different conditions. The results showed that their chromosomal number is 2n = 20 and the sex-determining mechanism is Xyp. The karyotype of Batocera lineolata is composed of 4 pairs of large autosomes, 5 pairs of medium sized autosomes and 1 pair of small sex-chromosome, and the karyotype formula is 4L +5M +Xyp. For Apriona germari, Olenecamptus cretaceus marginatus and Olenecamptus octopustulatus chinensis, their karyotypes are all composed of 5 pairs of large autosomes, 4 pairs of medium sized autosomes and 1 pair of medium sized sex-chromosome, and the karyotype formula is 5L + 4M + Xyp. The two long-horned beetles of Olenecamptus have very similar karyotype index. The chromosome size and the centromere location among A. germari, B. lineolata and Olenecamptus are obviously different.

    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)

    Photonic crystals (PCs) are periodic structures that manipulate electromagnetic waves by defining allowed and forbidden frequency bands known as photonic band gaps. Despite production of PC structures operating at infrared wavelengths, visible counterparts are difficult to fabricate because periodicities must satisfy the diffraction criteria. As part of an ongoing search for naturally occurring PCs [1], a three-dimensional array of nanoscopic spheres in the iridescent scales of the Cerambycidae insects A. elegans and G. celestis has been found. Such arrays are similar to opal gemstones and self-assembled colloidal spheres which can be chemically inverted to create a lattice-like PC. Through a chemical replication process [2], scanning electron microscopy analysis, sequential focused ion beam slicing and three-dimensional modeling, we analyzed the structural arrangement of the nanoscopic spheres. The study of naturally occurring structures and their inversing techniques into PCs allows for diversity in optical PC fabrication. [1] J.W. Galusha et al., Phys. Rev. E 77 (2008) 050904. [2] J.W.

    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.

    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. PMID:27126839

    Abstract The use of archery to hunt appears relatively late in human history. It is poorly understood but the application of poisons to arrows to increase lethality must have occurred shortly after developing bow hunting methods; these early multi-stage transitions represent cognitive shifts in human evolution. This paper is a synthesis of widely-scattered literature in anthropology, entomology, and chemistry, dealing with San (“Bushmen”) arrow poisons. The term San (or Khoisan) covers many indigenous groups using so-called ‘click languages’ in southern Africa. Beetles are used for arrow poison by at least eight San groups and one non-San group. Fieldwork and interviews with Ju|’hoan and Hai||om hunters in Namibia revealed major differences in the nature and preparation of arrow poisons, bow and arrow construction, and poison antidote. Ju|’hoan hunters use leaf-beetle larvae of Diamphidia Gerstaecker and Polyclada Chevrolat (Chrysomelidae: Galerucinae: Alticini) collected from soil around the host plants Commiphora africana (A. Rich.) Engl. and Commiphora angolensis Engl. (Burseracaeae). In the Nyae Nyae area of Namibia, Ju|’hoan hunters use larvae of Diamphidia nigroornata Ståhl. Larvae and adults live above-ground on the plants and eat leaves, but the San collect the underground cocoons to extract the mature larvae. Larval hemolymph is mixed with saliva and applied to arrows. Hai||om hunters boil the milky plant sap of Adenium bohemianum Schinz (Apocynaceae) to reduce it to a thick paste that is applied to their arrows. The socio-cultural, historical, and ecological contexts of the various San groups may determine differences in the sources and preparation of poisons, bow and arrow technology, hunting behaviors, poison potency, and perhaps antidotes.

    This synopsis provides an identification key to the genera of Tribe Lachnophorini of the Western and Eastern Hemispheres including five genera previously misplaced in carabid classifications. The genus Asklepia Liebke, 1938 is revised with 23 new species added and four species reassigned from Eucaerus LeConte, 1853 to Asklepia Liebke, 1938. In addition, a new genus is added herein to the Tribe: Peruphorticus gen. n. with its type species P. gulliveri sp. n. from Perú. Five taxa previously assigned to other tribes have adult attributes that make them candidates for classification in the Lachnophorini: Homethes Newman, Aeolodermus Andrewes, Stenocheila Laporte de Castelnau, Diplacanthogaster Liebke, and Selina Motschulsky are now considered to belong to the Lachnophorini as genera incertae sedis. Three higher level groups are proposed to contain the 18 recognized genera: the Lachnophorina, Eucaerina, and incertae sedis. Twenty-three new species of the genus Asklepia are described and four new combinations are presented.

    Full Text Available Following the description of the Apatophyseini genus Apterotoxitiades Adlbauer, 2008 (Cerambycidae: Dorcasominae from South Africa, a new species has now been discovered in the eastern Drakensberg range of the country. 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.

    Full Text Available Catchment landscape degradation and habitat modifications of freshwater ecosystems are a primary cause of biodiversity loss in riverine ecosystems all over the world. Many elements of the flora and fauna of freshwater ecosystems are sensitive to the changes in catchment land use and habitat modification. These sensitive taxa are also reliable indicators of freshwater ecosystem health. In the current study we investigate the seasonal and habitat distribution of Odonata (Insecta across riparian land use types in Mula and Mutha river basins, northern Western Ghats, Maharashtra. There was a difference in the species composition across land use types and across seasons with highest diversity and abundance during the post monsoon period. The highest Odonata diversity was observed in urban areas followed by forest and agriculture fields. There was a loss of 31% of the odonate fauna in the study area over 50 years which could be due to rapid industrialization and urbanization of the region and consequent degradation of freshwater ecosystems.

    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.

    The complete mitochondrial genome of the Scarlet Tiger moth Callimorpha dominula (Insecta: Lepidoptera: Arctiidae) has been reconstructed from the whole-genome Illumina sequencing data. This circular genome is 15 496 bp in size, and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and one A + T-rich D-loop or control region. Most PCGs are initiated with the ATN codons, except for COX1 with the unusual CGA as its initiation codon. Four PCGs (COX1, COX2, ND3, and ND4) are terminated with incomplete codon T, ND4L uses TAG as its termination codon, while all the other eight PCGs employ the usual ATN codons. The nucleotide composition is highly asymmetric (40.1% A, 40.9% T, 7.6% G, and 11.4% C) with an overall A + T content of 81.0%. The phylogenetic analysis based on the neighbor-joining (NJ) method suggests that C. dominula is more phylogenetically related to its confamilial counterparts than to those from other families.

    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.

    Hydropsyche angustipennis (Insecta, Trichoptera) larvae were used as indicators of stream contamination in the city of Łódź, Poland. The larvae of H. angustipennis were present at 9 sampling sites established for this study. Significant differences between the sampling sites were noted for environmental parameters as well as concentration of chemicals in water and biodiversity of aquatic invertebrates. Statistical analyses showed significant correlations between quantity and quality of water pollutants and density of H. angustipennis larvae, concentration of metals in larval bodies, and the appearance of morphological anomalies in tracheal gills and anal papillae. In comparison to literature data, the level of contaminants in water, including heavy metals, for each of the studied streams of Łódź was surprisingly low while concentration of these metals in the whole bodies of H. angustipennis larvae was very high. Some of the heavy metals present in the water might be identified only after conducting analyses of their concentration in the larval bodies. Therefore, long life cycle of H. angustipennis and heavy metal tolerance with a possibility of their accumulation in the larval bodies may constitute a support to traditional chemical assessment of water quality or traditional biomonitoring.

    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.

  2. Mitochondrial genome deletions and minicircles are common in lice (Insecta: Phthiraptera

    2011-08-01

    Full Text Available Abstract Background The gene composition, gene order and structure of the mitochondrial genome are remarkably stable across bilaterian animals. Lice (Insecta: Phthiraptera are a major exception to this genomic stability in that the canonical single chromosome with 37 genes found in almost all other bilaterians has been lost in multiple lineages in favour of multiple, minicircular chromosomes with less than 37 genes on each chromosome. Results Minicircular mt genomes are found in six of the ten louse species examined to date and three types of minicircles were identified: heteroplasmic minicircles which coexist with full sized mt genomes (type 1; multigene chromosomes with short, simple control regions, we infer that the genome consists of several such chromosomes (type 2; and multiple, single to three gene chromosomes with large, complex control regions (type 3. Mapping minicircle types onto a phylogenetic tree of lice fails to show a pattern of their occurrence consistent with an evolutionary series of minicircle types. Analysis of the nuclear-encoded, mitochondrially-targetted genes inferred from the body louse, Pediculus, suggests that the loss of mitochondrial single-stranded binding protein (mtSSB may be responsible for the presence of minicircles in at least species with the most derived type 3 minicircles (Pediculus, Damalinia. Conclusions Minicircular mt genomes are common in lice and appear to have arisen multiple times within the group. Life history adaptive explanations which attribute minicircular mt genomes in lice to the adoption of blood-feeding in the Anoplura are not supported by this expanded data set as minicircles are found in multiple non-blood feeding louse groups but are not found in the blood-feeding genus Heterodoxus. In contrast, a mechanist explanation based on the loss of mtSSB suggests that minicircles may be selectively favoured due to the incapacity of the mt replisome to synthesize long replicative products

    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.

The results showed that there was a significant negative correlation between the crown density and the ratio of infected oaks, and a significant positive correlation existed between the other two key factors and the ratio of infected oaks. Using these three key factors, a multiple regression model was established for risk analysis of the harm extent of Massicus raddei. The average difference degree was 0.174 2, so the model is suitable for risk assessment of the harm extent of the pest.

    Full Text Available Field collection in Nahavand county (Hamedan Province, Iran revealed 9 blister beetle (Col: Meloidae species from three different tribes of subfamily Meloinae. In tribe Mylabrini, Mylabris impressa Chevrolat 1837, Mylabris schreibersi Reiche 1865, Mylabris variabilis (Pallas, 1781, Mylabris guerini Chevrolat 1837, Lydoceras bilineatus Thomas 1897 and Croscherichia spp. Pardo Alcaide identified; whereas in tribe Lyttini Alosimus smyrnensis (Maran 1942 and Muzimes iranicus (Maran 1942 found. Another species was Calydos alloushei Kaszab 1960 of tribe Eupomphini. Two records of Mylabris impressa and Mylabris schreibersi are quite new for Iranian fauna. There are some interesting mimicry rings between meloid species and 8 species of other coleopteran families which indicates a remarkable Müllerian mimicry. Mimics of the following families have taken advantage of Meloid aposematism towards a better natural fitness: Cerambycidae, Cleridae, Pedilidae, Melyridae, Chrysomelidae, Cantharidae and Cicindelidae. Canthariphily of families Chrysomelidae, Cantharidae and Cerambycidae are new reports which have never been shown elsewhere.

    We determined the complete mitochondrial genome (mitogenome) sequence of Cryptolestes ferrugineus (GenBank accession number KT182067) by the long PCR and primer walking method. The mitochondrial genome is a typical circular DNA molecule of 15 511 bp in length, and contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a A + T-rich region (D-loop). The order of 37 genes was typical of insect mitochondrial DNA sequences described to date. The base composition of the genome is A (39.17%), T (37.24%), C (14.22%), and G (9.37%) with an A + T-rich hallmark as that of other invertebrate mitochondrial genomes. All protein-coding genes start with ATN codon and terminate with the stop codon T (AA) or TAG. The A + T-rich region is located between 12S rRNA and tRNA(Ile). In this study, the phylogenetic relationships of Coleoptera species were constructed based on the nucleotides sequences of 13 PCGs of mitogenomes. The molecular-based phylogeny supported the traditional morphological classification on relationships within Coleoptera species. PMID:26330111

    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.

    In this study, the complete mitochondrial genome of Cryptolestes pusillus (GenBank accession number KT070713) was sequenced by long PCR and primer walking methods. The total length of mitochondrial DNA is 15 502 bp and contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a A + T-rich region. The base composition of the genome is A (39.04%), T (37.07%), C (23.4%), and G (14.6%). Except for COI and ATP8 with TCC and ATC as start codon, respectively, the remaining protein-coding genes initiated with the three orthodox start codons. Two complete stop codons (TAA and TAG) and two incomplete stop codons (COIII stop with T and ND5 stop with TA) were used in the protein-coding genes. The A + T-rich region is located between 12s rRNA and tRNA(Ile) with the length of 859 bp. The phylogenetic relationships of Coleoptera species were constructed based on the nucleotide sequences of 13 protein-coding genes of mitogenome using the neighbor-joining method. The molecular-based phylogenetic analysis supported the traditional morphological classification on relationships within Coleoptera species. PMID:26329895

  1. Biology and Management of Billbugs (Coleoptera: Curculionidae) in Turfgrass

    Dupuy, Madeleine M.; Ramirez, Ricardo A.

    2016-01-01

    Billbugs (Coleoptera: Curculionidae: Sphenophorus spp.) are a complex of weevil pests affecting turfgrass throughout the United States. Billbug larvae cause damage by feeding in stems, on roots, and on the crowns of turf, causing severe discoloration and eventual plant death. Monitoring efforts have focused on nondestructive pitfall sampling of ground-active billbug adults and on destructive sampling using soil cores for larval stages in the soil. Given the cryptic nature of the susceptible larval stages, billbugs are typically managed by preventive applications of long-residual, systemic insecticides, including neonicotinoids and anthranilic diamides. Despite knowledge of effective management practices including pest-resistant turf varieties, irrigation management, and microbial controls that contribute to an IPM approach, billbug management continues to rely heavily on prophylactic synthetic insecticides. This review will summarize the identification and biology of billbugs and strategies for their management. PMID:27065080

    The family-group name DASYPODIDAE Borner, 1919 (Insecta, Hymenoptera) is a junior homonym Of DASYPODIDAE Gray, 1821 (Mammalia, Xenarthra). It is proposed that the homonymy between the two names, which relate to short-tongued bees and armadillos respectively, should be removed by emending the stem of the generic name Dasypoda Latreille, 1802, on which the insect familygroup name is based, to give DASYPODAIDAE, while leaving the mammalian name (based on Dasypus Linnaeus, 1758) unchanged. Dasypus novemcinctus Linnaeus, 1758, the type species of Dasypus, has a wide distribution in the southern United States, Central and South America. The genus Dasypoda ranges throughout most of the Palearctic region.

    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.

    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.

    [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

    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.

Thrips are tiny insects responsible for the reduction of strawberry fruit quality. The work aimed to record and quantify the thysanopterofauna present in two strawberry production systems, low tunnel and semi-hydroponic. Leaves, flowers and fruits were collected weekly, from July 2005 to December 2006 in Caxias do Sul and Bom Princípio municipalities, RS. A total of 664 individuals were collected, representing two families, four genus and 10 species: Frankliniella occidentalis (Pergande, 1895, F. schultzei (Trybom, 1910, F. rodeos Moulton, 1933, F. simplex (Priesner, 1924, F. williamsi (Hood, 1915, F. gemina (Bagnall, 1919, Frankliniella sp., Thrips tabaci (Lindeman, 1888, Thrips tabaci (Lindeman, 1888, Caliothrips fasciatus (Pergande 1895 from Thripidae and Heterothrips sp. from Heterothripidae. Frankliniella occidentalis represented 89.7% of the samples with 95.8% of the species collected in flowers, 3.9% in fruits and 0.8% in leaves. The results show that flowers are the most important food resource for these insects on strawberry plants. Frankliniella rodeos, F. simplex, F. williamsi, C. fasciatus, and Heterothrips sp. are new records on strawberry for Brazil.

  1. Multistate characters and diet shifts: evolution of Erotylidae (Coleoptera).

    Science.gov (United States)

    Leschen, Richard A B; Buckley, Thomas R

    2007-02-01

    The dominance of angiosperms has played a direct role in the diversification of insects, especially Coleoptera. The shift to angiosperm feeding from other diets is likely to have increased the rate of speciation in Phytophaga. However, Phytophaga is only one of many hyperdiverse lineages of beetles and studies of host-shift proliferation have been somewhat limited to groups that primitively feed on plants. We have studied the diet-diverse beetle family Erotylidae (Cucujoidea) to determine if diet is correlated with high diversification rates and morphological evolution by first reconstructing ancestral diets and then testing for associations between diet and species number and diet and ovipositor type. A Bayesian phylogenetic analysis of morphological data that was previously published in Leschen (2003, Pages 1-108 in Fauna of New Zealand, 47; 53 terminal taxa and 1 outgroup, 120 adult characters and 1 diet character) yielded results that are similar to the parsimony analyses of Leschen (2003). Ancestral state reconstructions based on Bayesian and parsimony inference were largely congruent and both reconstructed microfungal feeding (the diet of the outgroup Biphyllidae) at the root of the Erotylidae tree. Shifts among microfungal, saprophagous, and phytophagous diets were most frequent. The largest numbers of species are contained in lineages that are macrofungal feeders (subfamily Erotylinae) and phytophagous (derived Languriinae), although the Bayesian posterior predictive tests of character state correlation were unable to detect any significant associations. Ovipositor morphology correlated with diet (i.e., acute forms were associated with phytophagy and unspecialized forms were associated with a mixture of diets). Although there is a general trend to increased species number associated with the shift from microfungal feeding to phytophagy (based on character mapping and mainly restricted to shifts in Languriinae), there is a large radiation of taxa feeding on

    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.

    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

    Abstract Nearly 260 taxa and chromosomal races of subfamily Chrysomelinae have been chromosomally analyzed showing a wide range of diploid numbers from 2n = 12 to 2n = 50, and four types of male sex-chromosome systems. with the parachute-like ones Xyp and XYp clearly prevailing (79.0%), but with the XO well represented too (19.75%). The modal haploid number for chrysomelines is n = 12 (34.2%) although it is not probably the presumed most plesiomorph for the whole subfamily, because in tribe Timarchini the modal number is n = 10 (53.6%) and in subtribe Chrysomelina n = 17 (65.7%). Some well sampled genera, such as Timarcha, Chrysolina and Cyrtonus, are variable in diploid numbers, whereas others, like Chrysomela, Paropsisterna, Oreina and Leptinotarsa, are conservative and these differences are discussed. The main shifts in the chromosomal evolution of Chrysomelinae seems to be centric fissions and pericentric inversions but other changes as centric fusions are also clearly demonstrated. The biarmed chromosome shape is the prevalent condition, as found in most Coleoptera, although a fair number of species hold a few uniarmed chromosomes at least. A significant negative correlation between the haploid numbers and the asymmetry in size of karyotypes (r = -0.74) has been found from a large sample of 63 checked species of ten different genera. Therefore, the increases in haploid number are generally associated with a higher karyotype symmetry. PMID:22303104

    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)

    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.

    Therevidae (stilleto flies) are a little-known family of asiloid brachyceran Diptera (Insecta). Separate and combined phylogenetic analyses of 1200 bases of the 28S ribosomal DNA and 1100 bases of elongation factor-1alpha were used to infer phylogenetic relationships within the family. The position of the enigmatic taxon Apsilocephala Kröber is evaluated in light of the molecular evidence. In all analyses, molecular data strongly support the monophyly of Therevidae, excluding Apsilocephala, and the division of Therevidae into two main clades corresponding to a previous classification of the family into the subfamilies Phycinae and Therevinae. Despite strong support for some relationships within these groups, relationships at the base of the two main clades are weakly supported. Short branch lengths for Australasian clades at the base of the Therevinae may represent a rapid radiation of therevids in Australia. PMID:10860652

    Full Text Available First record of larvae of Chironomidae (Insecta, Diptera as prey of Temnocephala sp. (Platyhelminthes, Temnocephalidae, an ectosymbiont on larvae of Corydalidae (Megaloptera. 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.

    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.

    Full Text Available New records of Histeridae from Atlantic Canada are reported. Three species are newly recorded from Prince Edward Island and two from New Brunswick, one of which, the introduced Palearctic Atholus bimaculatus (Linnaeus, is newly recorded from Atlantic Canada as a whole. These new records increase the known histerid fauna of the region to 37 species, 30 native and 7 introduced ones. The regional zoogeography of the Histeridae is examined focusing on differences between the faunal composition of the various provinces and the possible reasons responsible for these. The island faunas of Cape Breton, Prince Edward Island, and Newfoundland are examined. All have reduced faunas in comparison with the mainland perhaps as a result of island-associated diminutions, an area effect, a paucity of collecting, or a combination of these factors. Those of Cape Breton and Prince Edward Island are proportionately similar to those of other families of Coleoptera, whereas that of Newfoundland (only 10% of the mainland fauna is significantly less, a circumstance which deserves further investigation. Seven species of introduced histerids have been recorded in the region. The average dates of first detection of these species are much later than the earliest records of these species in North America and comparatively later than is the case with other suites of introduced species in the Staphylinidae and Carabidae, perhaps as a result of the sparse attention the Histeridae have historically received by coleopterists in the region. Most of the introduced histerids are known to be synanthropic and may have been introduced to the region association with the importation of livestock and materials related to animal husbandry. The Histeridae of the region largely fall into one of several trophic guilds: coastal species and those associated with beach-drift material; species associated with bird nests; species associated with mammal nests; myrmecophilus species; saproxylic

    Full Text Available Abstract Background Problems associated with resistant mosquitoes and the effects on non-target species by chemicals, evoke a reason to find alternative methods to control mosquitoes, like the use of natural predators. In this regard, aquatic coleopterans have been explored less compared to other insect predators. In the present study, an evaluation of the role of the larvae of Acilius sulcatus Linnaeus 1758 (Coleoptera: Dytiscidae as predator of mosquito immatures was made in the laboratory. Its efficacy under field condition was also determined to emphasize its potential as bio-control agent of mosquitoes. Methods In the laboratory, the predation potential of the larvae of A. sulcatus was assessed using the larvae of Culex quinquefasciatus Say 1823 (Diptera: Culicidae as prey at varying predator and prey densities and available space. Under field conditions, the effectiveness of the larvae of A. sulcatus was evaluated through augmentative release in ten cemented tanks hosting immatures of different mosquito species at varying density. The dip density changes in the mosquito immatures were used as indicator for the effectiveness of A. sulcatus larvae. Results A single larva of A. sulcatus consumed on an average 34 IV instar larvae of Cx. quinquefasciatus in a 24 h period. It was observed that feeding rate of A. sulcatus did not differ between the light-on (6 a.m. – 6 p.m., and dark (6 p.m. – 6 a.m. phases, but decreased with the volume of water i.e., space availability. The prey consumption of the larvae of A. sulcatus differed significantly (P A. sulcatus larvae, while with the withdrawal, a significant increase (p A. sulcatus in regulating mosquito immatures. In the control tanks, mean larval density did not differ (p > 0.05 throughout the study period. Conclusion the larvae of the dytiscid beetle A. sulcatus proved to be an efficient predator of mosquito immatures and may be useful in biocontrol of medically important mosquitoes.

    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.

    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.

    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.

    Full Text Available In 2006-2007 we carried out faunal investigations in the vernal, estival and autumnal seasons in the scientific reserve "Codrul Secular Giumalãu" using quantitative sampling methods. We identified 189 species of Coleoptera, 70 of Collembola and 20 of Araneae. Of these, 11 phytophagous, 18 myceto/xylo-mycetophagous,9 mixophagous, 18 xylo- and cambio-xylemophagous, 38 saproxylophagous,125 (55 Coleoptera, 70 Collembola detritivorous (sapro-, copro- andnecrophagous, 60 (40 Coleoptera, 20 Aranea predators/parasitoids. Hymenaphorura polonica Pomorski, 1990 (Collembola, and Leiodes rhaeticus Erichson, 1845 (Coleoptera, Leiodidae, are recorded for the first time in the Romanian fauna. The rare species and characteristic species for the old primeval spruce forests are analysed for each studied taxonomic group. The species richness and faunal diversity from the Giumalãu primeval spruce forest are compared with those of other very well preserved forests from the Carpathians scientific reserves (Codrul Secular Slãtioara,Pietrosul Rodnei. The species abundances were used to compute the similarity indexes between the sampled sectors of forest and to perform Cluster Analysis. We observed that the dead wood in the 2nd-6th phases of decomposition has a great influence not only on the saproxylic species but also on the soil fauna like ground beetles(Carabidae that use the logs as ecologic microrefuges (winter refugees or diurnal refugees. The structure of the soil fauna is influenced by wood extraction from the forest ecosystem or by natural perturbations, this consisting in the appearance of opportunistic species as Orchesella pontica (Collembola and in decreasing ofspecies richness of Carabidae (Coleoptera.

    The hemipteran (Insecta) diversity in the upper part of the Kerian River Basin was low with only 8 families and 16 genera recorded at 4 study sites from 3 rivers. Water bug composition varied among sampling sites (Kruskal-Wallis χ (2) = 0.00, p0.05). All recorded water parameters were weakly associated with generic abundance but the biochemical oxygen demand (BOD), chemical oxygen demand (COD), Water Quality Index (WQI) and heavy metals (zinc and manganese) showed relatively strong positive or negative relations with hemipteran diversity and richness (H' and R2). Within the ranges of measured water parameters, the WQI was negatively associated with hemipteran diversity and richness, implying the tolerance of the water bugs to the level of pollution encountered in the river basin. Based on its highest abundance and occurrence (ISI), Rhagovelia was the most important genus and along with Rheumatogonus and Paraplea, these genera were common at all study sites. In conclusion, habitat availability and suitability together with some environmental parameters influenced the abundance and composition of hemipterans in this river basin. PMID:27073600

    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. PMID:27547607

    Full Text Available Dung beetles (Coleoptera, Scarabaeinae attracted to sheep dung in exotic pastures. In this study we provide data on the abundance and richness of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae attracted to sheep dung in exotic pastures (Brachiaria spp.. In four areas of exotic pasture pitfall traps were installed and baited with fresh sheep dung for sampling of dung beetles. A total of 2,290 individuals were captured belonging to 16 species, 10 genera and five tribes of Scarabaeinae beetles. Trichillum externepunctatum Preudhomme de Borre, 1886 and Dichotomius bos (Blanchard, 1843 were dominant. The guild of dwellers was the most abundant in pastures. We demonstrate that dung beetles are attracted to sheep dung. Since the production of both cattle and sheep in the same area is common in tropical pasturelands, results obtained here highlight the need to investigate the actual role of dung sharing (cattle dung + sheep dung by dung beetles. It is also suggested that experiments be performed for evaluation of the ecological functions performed by dung beetles using sheep dung.

    Bark beetles (Coleoptera: Scolytinae) are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis. However, very little is known about these fungi in Spain. In this study, we examined the fungi associated with 13 bark beetle species and one weevil (Coleoptera: Entiminae) infesting Pinus radiata in the Basque Country of northern Spain. This study included an examination of 1323 bark beetles or their galleries in P. radiata. Isolations yielded a total of 920 cultures, which included 16 species of Ophiostoma sensu lato or their asexual states. These 16 species included 69 associations between fungi and bark beetles and weevils that have not previously been recorded. The most commonly encountered fungal associates of the bark beetles were Ophiostoma ips, Leptographium guttulatum, Ophiostoma stenoceras, and Ophiostoma piceae. In most cases, the niche of colonization had a significant effect on the abundance and composition of colonizing fungi. This confirms that resource overlap between species is reduced by partial spatial segregation. Interaction between niche and time seldom had a significant effect, which suggests that spatial colonization patterns are rarely flexible throughout timber degradation. The differences in common associates among the bark beetle species could be linked to the different niches that these beetles occupy. PMID:17668036

    The complete mitochondrial genome (mitogenome) of Prosopocoilus gracilis (Coleoptera: Lucanidae) that is endemic to Southern China is determined. The circular genome is 736 bp in length and comprises 13 protein-coding genes, 22 tRNA, 2 rRNA genes and a control region. Gene order is identical to that of the putative ancestral arrangement of insects. The nucleotide composition of heavy strand is A (36.6%), C (22.6%), T (29.5%) and G (11.3%). All protein-coding genes start with a typical ATN codon except for the gene COI that uses AAC as the start codon. tRNA-Ser (AGN) uses the anticodon UCU instead of the commonly used GCU. Both maximum likelihood and Bayesian analyses support the monophyly of Lucanidae and the sister relationship of Nigidionus and the remaining sampled genera. Two species of Prosopocoilus were not recovered as a monophyletic group. PMID:26024142

  9. Communication disruption using synthetic sex pheromone for control of sugarcane wireworm. Melanotus okinawensis Ohira (Coleoptera: Elateridae)

    International Nuclear Information System (INIS)

    We tested communication disruption through the use of a synthetic sex pheromone from mid February to early June 2001 at the cultivating land on Minami-Daito Island in order to control the sugarcane wireworm Melanotus okinawensis Ohira (Coleoptera: Elateridae). Although very few males were caught in monitoring traps except a few traps set in a treated area, a large number were caught in traps set in an untreated Japanese pampas grass field. This indicates that communication disruption was effective throughout the period in the treated area. Females collected from treated area of Minami-Daito Island, mating rates that were lower than those of females in the untreated areas on Miyagi Island. We therefore concluded that a communication disruption system is an effective tool for the sugarcane wireworm management. (author)

    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.

    For the first time, a set of 56 compounds representing structural derivatives of naturally occurring alpha-asarone as an antifeedants against stored product pests Sitophilus granarius L., Trogoderma granarium Ev., and Tribolium confusum Duv., were subjected to the 3D QSAR studies. Three-dimensional quantitative structure-activity relationships (3D-QSAR) for 56 compounds, including 15 newly synthesized, were performed using comparative molecular field analysis s-CoMFA and SOM-CoMSA techniques. QSAR was conducted based on a combination of biological activity (against Coleoptera larvae and beetles) and various geometrical, topological, quantum-mechanical, electronic, and chromatographic descriptors. The CoMSA formalism coupled with IVE (CoMSA-IVE) allowed us to obtain highly predictive models for Trogoderma granarium Ev. larvae. We have found that this novel method indicates a clear molecular basis for activity and lipophilicity. This investigation will facilitate optimization of the design of new potential antifeedants.

    Three new species of the Cape high-mountain stag beetle genus, Colophon Gray (Coleoptera: Lucanidae), from South Africa are described. They are C. deschodti new species, C. switalae new species, and C. struempheri new species. The new taxa fall within a species complex of geographically disjunct entities related to Colophon stokoei Barnard. Furthermore, the mitochondrial COI gene shows a high degree of sequence divergence, with pairwise genetic distances between the species ranging between 7.4-10.7%. The new species are illustrated by photographs. Colophon eastmani nagaii Mizukami is raised to species level on the basis of geographic range and molecular differences between it and the nominate subspecies. This brings the total number of described species in the genus to 21. An updated checklist of the South African species of Colophon is also provided. PMID:26701471

    Full Text Available Carpophilus zeaphilus Dobson, 1969 (Coleoptera, Nitidulidae, Carpophilinae is an Afrotropical species that has become widespread in Sub-Saharan Africa, the Arabian Peninsula, and southern Mediterranean areas in recent years. The species was first recorded from Europe in Portugal and Spain nearly thirty years ago, and it was later intercepted in Sicily near Trapani in 1991. A few specimens of this species were collected in April, 2015 in a sparsely forested area near Rome, which suggests a recent acclimatization into peninsular Italy. Specimens were taken on flowering trees of Prunus spinosa L. (Rosaceae, an unusual occurrence for most introduced species of Carpophilinae that are normally associated with rotten fruit and other decomposing vegetal matter.

    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.

    Epitrix species (Coleoptera: Chrysomelidae) feed mostly on plants from the family Solanaceae and some of them are major pests of potato crops. All Epitrix species are morphologically highly similar, which makes them difficult to identify and limits their study and management. Identification of species is mostly based on the observation of the genitalia and requires a high level of expertise. Here, we propose a tool to reliably identify all developmental stages of the most economically important Epitrix species feeding on potato in Europe and North America (Epitrix cucumeris, Epitrix similaris, Epitrix tuberis, Epitrix subcrinita and Epitrix hirtipennis). We first sequenced two DNA markers (mitochondrial cytochrome c oxidase I (COI) and nuclear internal transcribed spacer 2 (ITS2)) to test their effectiveness in differentiating among six Epitrix species (126 specimens). Morphospecies of Epitrix were well-differentiated by both DNA barcodes and no mitochondrial introgression was detected. Then, we developed an RFLP-based diagnostic method and showed that unambiguous species discrimination can be achieved by using the sole restriction enzyme TaqI on COI polymerase chain reaction products. The tool proposed here should improve our knowledge about Epitrix species biology, distribution and host range, three capacities that are particularly important in the detection and management of these pest species. Specifically, this tool should help prevent the introduction of E. tuberis and E. subcrinita in Europe and limit the spread of the recently introduced E. cucumeris and E. similaris, with minimal disruption to Solanaceae trade.

    The crucifer flea beetle, Phyllotreta cruciferae (Goeze) (Coleoptera: Chrysomelidae), has recently emerged as a serious pest of canola (Brassica napus L.) in Montana. The adult beetles feed on canola leaves, causing many small holes that stunt growth and reduce yield. In 2013, damage to canola seedlings was high (approximately 80%) in many parts of Montana, evidence that when flea beetles emerge in large numbers, they can quickly destroy a young canola crop. In the current study, the effectiveness of several biopesticides was evaluated and compared with two insecticides (deltamethrin and bifenthrin) commonly used as foliar sprays as well as seed treatment with an imidacloprid insecticide for the control of P. cruciferae under field conditions in 2013. The biopesticides used included an entomopathogenic nematode (Steinernema carpocapsae), two entomopathogenic fungi (Beauveria bassiana and Metarhizium brunneum), neem, and petroleum spray oils. The control agents were delivered in combination or alone in a single or repeated applications at different times. The plant-derived compound neem (azadirachtin), petroleum spray oil, and fatty acids (M-Pede) only showed moderate effect, although they significantly reduced leaf injuries caused by P. cruciferae and resulted in higher canola yield than the untreated control. Combined use of B. bassiana and M. brunneum in two repeated applications and bifenthrin in five applications were most effective in reducing feeding injuries and improving yield levels at both trial locations. This indicates that entomopathogenic fungi are effective against P. cruciferae, and may serve as alternatives to conventional insecticides or seed treatments in managing this pest. PMID:24772547

  14. Radiobiology of Small Hive Beetle (Coleoptera: Nitidulidae) and Prospects for Management Using Sterile Insect

    International Nuclear Information System (INIS)

    Small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), is considered a serious threat to beekeeping in the Western Hemisphere, Australia, and Europe mainly due to larval feeding on honey, pollen, and brood of the European honeybee, Apis mellifera L. Control methods are limited for this pest. Studies were conducted to provide information on the radiobiology of small hive beetle and determine the potential for sterile insect releases as a control strategy. Adult males and females were equally sensitive to a radiation dose of 80 Gy and died within 5–7 d after treatment. In reciprocal crossing studies, irradiation of females only lowered reproduction to a greater extent than irradiation of males only. For matings between unirradiated males and irradiated females, mean reproduction was reduced by >99% at 45 and 60 Gy compared with controls, and no larvae were produced at 75 Gy. Irradiation of prereproductive adults of both sexes at 45 Gy under low oxygen (1–4%) caused a high level of sterility (>99%) while maintaining moderate survivorship for several weeks, and should suffice for sterile insect releases. Sterile insect technique holds potential for suppressing small hive beetle populations in newly invaded areas and limiting its spread. (author)

    The complete mitochondrial genome (mitogenome) of Tribolium castaneum (Coleoptera: Tenebrionidae) was determined to be 15,883 bp (GenBank accession No. KM009121), which contains 22 tRNA genes, 13 protein-coding genes (PCGs), 2 rRNA genes and a major non-coding A + T-rich region. It has the typical gene organization and order of mitogenomes from ancestral insects. The nucleotide composition was also biased toward A + T nucleotides (71.72%) and the AT skew of this mitogenome was slightly positive. All of the 22 tRNA genes displayed a typical clover-leaf structure, with the exception of trnS1 (AGN). Thirteen PCGs were initiated by ATN codons, except for cytochrome c oxidase subunit 1 (cox1) gene which was initiated by AAT. Eight of the 13 PCGs harbor the incomplete termination codon by T or TA. The A + T-rich region of the mitogenome was 1237 bp in length and the A + T content was 82.30%. PMID:25162515

    Full Text Available We describe the morphology and microstructure of the egg chorion, and the morphology of the first instar larva of Gyriosomus luczotii Laporte, 1840 (Coleoptera, Tenebrionidae, Nycteliini. Bionomical and distributional data on this species are also provided. To obtain eggs and larvae, couples were collected in the field and kept in rearing cages until oviposture and ecclosion. The structure and adornment of the egg exochorion, and the exterior morphological features of larvae were examined with electron scanning microscopy. The eggs of G. luczotii showed a rounded micropyle and a smooth exochorion, composed of hexagonal cells without aeropyles. The larvae of G. luczotii showed morphological characteristics suited for an edaphic life similar to that of Pedobionta: digging prothoracic legs, cephalic capsule with abundant sensilla, and well–developed pygopodium. We analysed the importance of larval morphology as an element for specific diagnosis and found that interspecific differences regarding frontal sensilla, clypeus shape, and anterior part of labrum, had a taxonomic value and possibly a phylogenetic value.

    The aim of this study was to describe the karyotype of species belonging to the subfamily Scarabaeinae (Coleoptera, Scarabaeidae) and to compile the conventional cytogenetic data available in the literature for this group. The karyotypes of ten species belonging to the tribes Canthonini, Coprini, Onthophagini and Phanaeini were analyzed by conventional staining. Eight of these species were described for the first time (Canthon aff carbonarius, Canthon chalybaeus, Coprophanaeus dardanus, Deltochilum aff amazonicum, Dichotomius geminatus, Oxysternon silenus, Phanaeus chalcomelas and Malagoniella aff astyanax) and two were redescribed (Diabroctis mimas and Digitonthophagus gazella) since their karyotypes differed from those previously published in the literature. Four species studied showed a diploid number of 2n=20 and a parachute type sex determining system and the karyotype was 2n=20,Xy in two species and 2n=18,Xy(p), 2n=19,X0, 2n=12,XY and 2n=14,neoXY in one each. The chromosome morphology of the different species varied, with the observation of metacentric, submetacentric, subacrocentric and acrocentric chromosomes. The X chromosome was predominantly meta or submetacentric in the species analyzed, whereas the y chromosome presented two arms or was punctiform. In conclusion, the subfamily Scarabaeinae comprises 120 species analyzed cytogenetically, and are observed the occurrence of five chromosome rearrangements (autosome-autosome and X-autosome fusions, pericentric inversions, fissions and loss of the y chromosome) that are related to the chromosome variability and evolution in the group.

    Full Text Available We evaluated the damage patterns produced by females of the guava weevil Conotrachelus dimidiatus Champion, 1904 (Coleoptera: Curculionidae, according to the position of the damaged fruit in guava trees Psidium guajava L. in Calvillo, Aguascalientes, Mexico. The trees were subdivided in eight zones, and during one year the level of fruit lesions due to oviposition was registered. Results showed a higher level of damage in the upper and external zone of the trees (P≤.05. We found no significant differences in damage between the four cardinal points (P≥.05. During the year, the level of damage was recorded and was higher in the months of August and September (P≤.05 associated with rainfall (0.86, P=.06 and increase in temperature (0.84, P=.03. The most susceptible fruits were in the size range of 2.1–4.0 cm (polar diameter. The information from this study will be used to design and establish effective control strategies for the guava weevil, taking into account location of the most susceptible fruits, seasonality of the pest, and the abiotic factors.

    Full Text Available In most beetles, the hind wings are thin and fragile; when at rest, they are held over the back of the beetle. When the hind wing unfolds, it provides the necessary aerodynamic forces for flight. In this paper, we investigate the hydraulic mechanism of the unfolding process of the hind wings in Dorcus titanus platymelus (Oder: Coleoptera. The wing unfolding process of Dorcus titanus platymelus was examined using high speed camera sequences (400 frames/s, and the hydraulic pressure in the veins was measured with a biological pressure sensor and dynamic signal acquisition and analysis (DSA during the expansion process. We found that the total time for the release of hydraulic pressure during wing folding is longer than the time required for unfolding. The pressure is proportional to the length of the wings and the body mass of the beetle. A retinal camera was used to investigate the fluid direction. We found that the peak pressures correspond to two main cross-folding joint expansions in the hind wing. These observations strongly suggest that blood pressure facilitates the extension of hind wings during unfolding.

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

    Full Text Available A five year study has been made to establish the spread of the rice water weevil Lissorhoptrus oryzophilus (Coleoptera: Erirhinidae in Northern Italy. Data obtained with GPS from 2005 throughout 2009 were first georeferenced with SW ArcGis® 9.2, then overlapped and compared to the map of the European environmental landscape based on the interpretation of satellite images (CORINE Land Cover map and to the hydrographic chart CT10 (Technical Regional map 10000. The analysis of the radial rate of spread per year indicates a deceleration in the expansion from 10.864 ± 6.801 km/year in 2005 to 5.318 ± 1.401 km/year in 2009. In five years the weevil has expanded its distribution in nearly all rice paddies in Lombardy and Piedmont, over an area of about 200,000 ha, which correspond to 86% of the total Italian rice area. Its expansion is thought to follow a type of stratified dispersal, due both to insect adult active dispersal and to accidental movements caused by human transportation.

    Full Text Available Bark beetles (Coleoptera: Curculionidae: Scolytinae belong to one of the most damaging groups of forest insects and the activity of their natural enemies –pathogens, parasitoids,parasites or predators suppressing their population density,is of great importance. Biodiversity of entomopathogenic fungi on bark beetles in Bulgaria has been investigated sporadically. The aim of this preliminary study was to find, identify and study morphological characteristics of fungal entomopathogens naturally-occurring in populations of three curculionid species – Ips sexdentatus Boern, Ips typographus (L. and Dryocoetes autographus (Ratz.. Dead pest adults were found under the bark of Pinus sylvestris and Picea abies trees collectedfrom forests in the Maleshevska and Vitosha Mountains. Fungal pathogens were isolated into pure cultures on SDAY (Sabouraud dextrose agar with yeast extract and were identified based on morphological characteristics both on the host and in a culture.Morphological characteristics of the isolates were studied by phenotypic methods. The fungal isolates obtained from dead adults of Ips sexdentatus, Ips typographus and D. autographus were found to belong to the species Beauveria bassiana (Bals. – Criv. Vuillemin,Beauveria brongniartii (Saccardo Petch and Isaria farinosa (Holmsk. Fries (anamorph Ascomycota, Sordariomycetes: Hypocreales, Cordycipitaceae. Morphological traits of the isolates are described.

    Plant-based insecticides can play an important role in integrated insect pest management (IPM), especially in protecting stored grains. The aim of this study was to evaluate the bioactivity of derivatives (powder, ethanolic extract, and essential oil (EO)) from the leaves of Pimenta pseudocaryophyllus (Myrtaceae), a Brazilian native species, against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), the main insect pest of stored corn. The powder and essential oil prepared from leaves showed a repellent effect. Moreover, the EO exhibited promising insecticidal activity through residual contact (LC50 = 1522 mg kg(-1)) and significantly decreased the F 1 progeny and the percentage of damaged grains. However, the essential oil obtained from P. pseudocaryophyllus leaves did not result in significant mortality of S. zeamais adults after 72 h of exposure by fumigation in concentrations up to 400 μL L(-1) of air. Based on GC-MS analysis, 20 compounds were identified in the essential oil of P. pseudocaryophyllus leaves, being chavibetol (38.14%), methyl eugenol (11.35%), and terpinolene (9.17%) as the major constituents. Essential oil from P. pseudocaryophyllus leaves is an interesting source of compounds with grain-protectant properties and should be analyzed in future studies aiming to develop new bioinsecticides to use in the IPM of stored grains.

    Full Text Available Competition and cooperation between bark beetles, Tomicus yunnanensis Kirkendall and Faccoli and Tomicus minor (Hartig (Coleoptera: Scolytinae were examined when they coexisted together in living Yunnan pine trees (Pinus yunnanensis Franchet in Yunnan province in Southwest China. T. yunnanensis bark beetles were observed to initiate dispersal from pine shoots to trunks in November, while the majority of T. minor begins to transfer in December. T. yunnanensis mainly attacks the top and middle parts of the trunk, whereas T. minor mainly resides in the lower and middle parts of the trunk. The patterns of attack densities of these two species were similar, but with T. yunnanensis colonizing the upper section of the trunk and T. minor the lower trunk. The highest attack density of T. Yunnanensis was 297 egg galleries/m2, and the highest attack density of T. minor was 305 egg galleries/m2. Although there was significant overlap for the same bark areas, the two species generally colonize different areas of the tree, which reduces the intensity of competition for the relatively thin layer of phloem-cambium tissues where the beetles feed and reside.

  5. Factors Affecting Pheromone Production by the Pepper Weevil, Anthonomus eugenii Cano (Coleoptera: Curculionidae and Collection Efficiency

    2014-11-01

    Full Text Available Several factors affecting pheromone production by male pepper weevils, Anthonomus eugenii Cano (Coleoptera: Curculionidae as well as collection efficiency were investigated. Factors studied included: porous polymer adsorbents (Tenax versus Super Q, male age, time of day, male density, and male diet. Super Q was found to be a superior adsorbent for the male-produced alcohols and geranic acid as well as the plant-produced E-β-ocimene. Pheromone production increased with male age up to about age 15 days old and then tapered off. Male pepper weevils produced the highest amount of pheromone between noon and 2 pm (i.e., 4 to 6 h after “lights on” and were producing ca. 800 ng/h during this period. Thereafter, pheromone production decreased and was extremely low during the scotophase (i.e., ca. 12 ng/h. Male pepper weevil density had a significant effect on both release rate and pheromone composition. Pheromone production on a per male basis was highest for individual males and the percentage of geranic acid in the blend was lowest for individual males. Male pepper weevils produced only extremely low amounts of pheromone when feeding on artificial diet; however, they produced very high amounts when on fresh peppers. Together, this information will be useful in designing better attractant lures for pepper weevils.

    2011-03-01

    Full Text Available The present study was undertaken to screen some plants belonging to family Lamiaceae against Callosobruchus chinensis Linn.. Among fourteen important insect pests of stored grains, the pulse beetle C. chinensis (Coleoptera: Bruchidae is one such pest causing considerable damage to stored pulses. The eggs are laid on the host grains; the larvae bore inside and after feeding and pupating emerge out as adults leaving behind damaged hollow seed-grains. Looking into the hazards of chemical insecticides, there is an utmost need to search for some alternate methods for protection against the damage caused by insects. The leaves of the select plants viz., Ocimum basilicum, O. sanctum and Mentha spicata were employed in the form of various formulations and mortality of the pest insect was assessed. A significant increase in mortality of C. chinensis was observed in all the experimental sets as compared to normal and control sets during the present study. When comparisons were made on the basis of ANOVA to compare the effect of the three plants on mortality, it was found that the treatments of O. basilicum were superior over M. spicata and O. sanctum. The findings overall suggest that all the three plants screened have a potential to be used against the pest C. chinensis and can be employed as an alternate to chemical insecticides in household and storehouses to minimize the infestation and damage caused by the bruchid.

During the samplings carried out in the rainy station on 2008, were captured a total of 177 individuals belonging to 9 species. The tribe Canthonini was the most representative with 87.5%, of the described species, followed by Aechini 10.8%, and Onthophagini 1.7%. The dominant species was Canthon lituratus in the three vegetation units: Lower montane rain forest was the richest (9 species and abundance (86 individuals, compared with other environments sampled. By calculating the complementarity index, shows a similar species composition in the three habitats sampled, possibly, related to the floristic composition presented in each one of them.

    The firefly, Luciola substriata (Coleoptera: Lampyridae), is an aquatic firefly species, whose larvae inhabit ponds or lakes. Here we present the complete mitochondrial (mt) genome of the firefly (GenBank accession number KP313820) and provide its annotation. This circular genome is 16,248 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a non-coding AT-rich region. Similar to other firefly species, the base composition of this mitochondrial genome is also biased toward A and T (44.09% A, 34.00% T, 12.89% C, and 9.01% G). All 13 protein-coding genes start with a typical mitochondrial start codon, and terminate with a usual stop codon TAA, or TAG or a single T. The non-coding AT-rich region (1636 bp in length) include one (A)20, and two (T)15 tandem repeats, and one (AAT)5 element. This mitochondrial genome sequence will promote a better understanding for firefly evolution in the future. PMID:25714154

    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 SNMP) genes. BLASTX best hit results indicated that these chemosensory genes were most identical to their respective orthologs from Tribolium castaneum. Phylogenetic analyses also revealed that the T. 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.

    Full Text Available The cave-associated invertebrates of Nova Scotia constitute a fauna at a very early stage of post-glacial recolonization. TheColeoptera are characterized by low species diversity. A staphylinid Quedius spelaeus spelaeus, a predator, is the only regularlyencountered beetle. Ten other terrestrial species registered from cave environments in the province are collected infrequently. Theyinclude three other rove-beetles: Brathinus nitidus, Gennadota canadensis and Atheta annexa. The latter two together with Catopsgratiosus (Leiodidae constitute a small group of cave-associated beetles found in decompositional situations. Quedius s. spelaeusand a small suite of other guanophiles live in accumulations of porcupine dung: Agolinus leopardus (Scarabaeidae, Corticariaserrata (Latrididae, and Acrotrichis castanea (Ptilidae. Two adventive weevils Otiorhynchus ligneus and Barypeithes pellucidus(Curculionidae collected in shallow cave passages are seasonal transients; Dermestes lardarius (Dermestidae, recorded fromone cave, was probably an accidental (stray. Five of the terrestrial beetles are adventive Palaearctic species. Aquatic beetles arecollected infrequently. Four taxa have been recorded: Agabus larsoni (Dytiscidae may be habitual in regional caves; another Agabussp. (probably semivittatus, Dytiscus sp. (Dytiscidae, and Crenitis digesta (Hydrophilidae are accidentals. The distribution andecology of recorded species are discussed, and attention is drawn to the association of beetles found in a Nova Scotia “ice cave”.

    Full Text Available ABSTRACT Abaris basistriata, a beetle species dominant in agroecosystems and natural habitats, may benefit from the establishment of nearby refuge areas or crop field centers. To confirm this hypothesis, we analyzed the spatial distribution of the species and verified the population dynamics of this predator in a soybean/corn rotation crop and a central refuge area. The 1-ha experimental area was divided in half by a range of herbaceous plants (2 m in width and 80 m in length. Beetle samples were collected using pitfall traps every fortnight during the in-season and every month during the off-season (a total of 27 sampling occurrences. Population fluctuation was analyzed by correlating the total number of specimens with plant phenology. We used multiple regression analysis with variable (stepwise selection to examine the influence of meteorological factors on species occurrence. To determine the spatial distribution, data were analyzed using dispersion indices and probabilistic models based on the Coleoptera frequency distribution. Distribution visualization was assessed using a linear interpolation map. A total of 143 A. basistriata specimens were collected, with 83 from the soybean/corn area and 60 from the refuge area. Periods of large population size occurred during a season with high rainfall and high maximum and minimum temperatures. On the basis of the spatial distribution analysis of A. basistriata, it is likely that the beetles occur in an aggregate form, preferably in the refuge area.

    Full Text Available Susceptibility of Alphitobius diaperinus (Panzer (Coleoptera, Tenebrionidae to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, Alphitobius diaperinus (Panzer, is an important insect pest in poultry houses in Brazil. Susceptibility of the lesser mealworm collected from eight poultry houses in Paraná state, southern Brazil, was evaluated for cypermethrin, dichlorvos and triflumuron. Adult A. diaperinus were tested in bioassays with cypermethrin and dichlorvos. Larvae were fed rabbit feed wetted with a triflumuron-water solution. Concentration-mortality regressions were estimated using Probit analysis and resistance ratios were calculated based on the susceptible population. Among the field populations evaluated, cypermethrin LC50 values for adults, ranged from 68.1 to 6,263 ng (AI/cm². LC50 values for adults challenged with dichlorvos ranged from 10.3 to 1,385 ng (AI/cm². One population from Pato Branco showed reduced susceptibility to triflumuron (LC50 = 272 µg (AI/ml of solution when compared to the most susceptible population (LC50 = 109.8 µg (AI/ml. Application of cypermethrin and dichlorvos analogues should be managed with caution to minimize insecticide resistance problems.

    We compared abundance, species richness, and capture efficiency with pitfall traps and mini-Winkler extractors to examine their use as complementary methods for sampling soil Coleoptera during dry (2010) and high water seasons (2011) in three areas, including inundated and non-inundated regions, in the Pantanal of Poconé, Mato Grosso, Brazil. We paired treatments with two 10 × 10 m plots in inundated and non-inundated locations that were repeated three times in each location for a total of 18 plots. In each plot, we used nine pitfall traps and collected 2 m(2) of leaf litter and surface soil samples with mini-Winkler extractors. We collected a total of 4260 adult beetles comprising 36 families, 113 genera, and 505 species. Most were caught in pitfalls (69%) and the remainder in the mini-Winkler extractors (31%). Each method provided distinct information about the beetle community: 252 species were captured only in pitfall traps, 147 using only the mini-Winkler extractors, and these methods shared another 106 species. Pitfall and mini-Winkler contribute in different ways for the sampling of the soil beetle community, and so they should be considered complementary for a more thorough assessment of community diversity.

    Litter-dwelling ground beetle (Coleoptera: Carabidae) assemblages were monitored 1 yr after the construction of a corridor for installation of an oil pipeline along a xeric ridge-top forest in southeastern Ohio. After the creation of the corridor, three distinct habitats were evident in these sites: open corridor, ecotone areas around the corridor, and undisturbed forest interior. Carabidae were collected using directional pitfall traps that were placed parallel and perpendicular to the corridor in each of the three habitats. Results indicate that more carabids were present in the ecotone than in the other two habitats. Carabid diversity as estimated by rarefaction was highest in the corridor followed by ecotone and forest interior. Generalist and forest specialists such as Synuchus impunctatus (Say), Carabus goryi Dejean, and Pterostichus trinarius (Casey) were present in greater numbers in the forest interior and ecotone assemblages. In contrast, open-habitat specialists such as Harpalus pensylvanicus (DeGeer) and Selenophorus opalinus (LeConte) were present in greater numbers in the corridor assemblages. Carabid assemblages of the corridor were distinct from those of the ecotone and forest interior, whereas the latter two habitats had very similar assemblages. The successional pathway of the corridor carabid assemblage will therefore be likely different from that of the forest interior and ecotone. Overall, results indicate that construction of the oil pipeline corridor had significant short-term effects on the carabid numbers, diversity, and species composition because of ensuing habitat changes and fragmentation of the forest.

    Stenusine is well known as the alkaloid, discharged by the rove beetle, genus Stenus Latreille (Coleoptera, Staphylinidae). The Stenus beetles employ the alkaloid as an escape mechanism when on water surfaces. In the case of danger, they lower their abdomen and emit stenusine from their pygidial glands. Stenusine shows a low surface tension and therefore a high spreading pressure; these properties propel the beetle quickly over the water. Many Steninae do not live in habitats with open waters, but in detritus, leaf litter, mosses, etc. This raises the possibility that stenusine might also have another function, e.g., as antibiotic or fungicide. Stenus beetles show an intense grooming behaviour. With gas chromatography mass spectrometry analyses we could prove that they cover themselves with their secretion. To tests its antimicrobial properties we conducted agar diffusion tests with stenusine and norstenusine, another substance that is abundant in most Stenus species. Both compounds have an antimicrobial effect on entomopathogenic bacteria and fungi. Stenusine not only allows for an extraordinary method of locomotion on water surfaces, it also protects the Steninae from being infested with microorganisms.

    Understanding how temperature affects fitness is important for conservation and pest management, especially in the era of global climate change. Rhynchophorus ferrugineus (Oliver) (Coleoptera: Curculionidae) is a worldwide pest of many economically important crops. Although much is known about this pest's life cycle, its adaptability to different temperatures is not fully understood. Here, we used age- and stage-specific life tables to investigate the effects of temperature on fitness-related traits and demographic parameters of R. ferrugineus under eight constant temperature regimens in the laboratory. The growth potential of these populations was also evaluated. The greatest longevity for males and females was 158.0 d at 24 °C and 144.5 d at 21 °C, respectively, but mean total fecundity was the highest at 27 °C. The intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R0) increased initially at low temperatures and then decreased. All metrics reached a maximum at 27 °C and a minimum at 36 °C. Mean generation times (T ) decreased across the temperature range with a minimum at 36 °C. Our results indicate that the optimum temperature for growth of R. ferrugineus was approximately 27 °C. Our work will be of value for developing strategies for control management of this pest species. PMID:27545594

    Stenusine is well known as the alkaloid, discharged by the rove beetle, genus Stenus Latreille (Coleoptera, Staphylinidae). The Stenus beetles employ the alkaloid as an escape mechanism when on water surfaces. In the case of danger, they lower their abdomen and emit stenusine from their pygidial glands. Stenusine shows a low surface tension and therefore a high spreading pressure; these properties propel the beetle quickly over the water. Many Steninae do not live in habitats with open waters, but in detritus, leaf litter, mosses, etc. This raises the possibility that stenusine might also have another function, e.g., as antibiotic or fungicide. Stenus beetles show an intense grooming behaviour. With gas chromatography-mass spectrometry analyses we could prove that they cover themselves with their secretion. To tests its antimicrobial properties we conducted agar diffusion tests with stenusine and norstenusine, another substance that is abundant in most Stenus species. Both compounds have an antimicrobial effect on entomopathogenic bacteria and fungi. Stenusine not only allows for an extraordinary method of locomotion on water surfaces, it also protects the Steninae from being infested with microorganisms. PMID:18392795

    Curculio longinasus Chittenden, 1927 (Coleoptera: Curculionidae), is a weevil species common throughout the southwestern United States that uses its rostrum - a very slender, curved, beak-like projection of the head - to excavate tunnels in plant organs (such as acorns) for egg laying (oviposition). Once the apical portion of the rostrum has been inserted into the preferred substrate for oviposition, the female begins rotating around the perimeter of the hole, elevating her head by extending the fore-legs, and rotating the head in place in a drilling motion. This action causes significant elastic deformation of the rostrum, which will bend until it becomes completely straight. To better understand the mechanical behavior of the cuticle as it undergoes deformation during the preparation of oviposition sites, we develop a comprehensive micro/macro model of the micromechanical structure and properties of the cuticle, spanning across all cuticular regions, and reliably mirroring the resultant macroscale properties of the cuticle. Our modeling approach relies on the use of multi-scale, hierarchical biomaterial representation, and employs various micromechanical schemata - e.g., Mori-Tanaka, effective field, and Maxwell - to calculate the homogenized properties of representative volume elements at each level in the hierarchy. We describe the configuration and behavior of this model in detail, and discuss the theoretical implications and limitations of this approach with emphasis on future biomechanical and comparative evolutionary research. Our detailed account of this approach can thereby serve as a methodological template for exploring the biomechanical behavior of new insect structures. PMID:27189867

    Eucryptorrhynchus chinensis Olivier (Coleoptera: Curculionidae) is one of the most important pests of Ailanthus altissima; however, so far, no studies on the genome or transcriptome of E. chinensis have been reported. Using the Roche 454 FLX Titanium platform, an RNA pool obtained from E. chinensis eggs, larva, pupae, and adults was sequenced and assembled de novo to achieve maximum diversity of sampled transcripts. We obtained 1,441,137 (∼518 Mb) raw reads with an average length of 360 bp. After trimming, 89% qualified reads were produced and assembled into 35,509 isotigs with an average length of 440 bp, N50 of 1,048 bp, and 111,643 singletons. We generated 87,894 unigenes following a cluster analysis of the isotigs and singletons, and then functionally annotated the unigenes with gene descriptions. We obtained 23,363 GO assignments, and 12,724 unigenes were assigned to KOG. Based on these annotations, 294 biochemical pathways involved in growth, reproduction, and stress or immune responses were predicted. A total of 659,026 single nucleotide variants and 6,112 simple sequence repeats were detected. Our data provide comprehensive information on the sequence and possible functions of E. chinensis transcripts.

    Tenebrionidae is a diverse insect family of Coleoptera that shows high levels of endemicity in epigean species. For the Andean region, which is divided into three subregions: Central Chilean, Subantarctic and Patagonian, it has been hypothesized that epigean tenebrionids have diversified in the Patagonian subregion and subsequently, they dispersed to Subantarctic and Central Chilean subregions. In this work, based on information obtained from museum collections and scientific studies, we presented the first list of endemic epigean tenebrionids from the Andean region with their taxonomic arrangement and geographic distribution. Moreover, we used these data to explore the veracity of the Patagonian-diversification hypothesis. A total of 416 species grouped into six subfamilies, 17 tribes and 41 genera were identified as endemic to the Andean region. Considering the spatial distribution it was observed that subfamilies, tribes, genera and species were unequally distributed across subregions. Results did not support the Patagonian-diversification hypothesis; to the contrary, they were more concordant with processes of isolation among subregions that have promoted speciation by interrupting gene flow among populations, resulting in endemism because species can not expand their range sizes. Finally, we discuss the implications of our findings to be considered in biodiversity conservation, because endemic species, by their high extinction risk, are primary targets in conservation strategies.

    The bacterium Yersinia entomophaga was isolated from larvae of the New Zealand grass grub, Costelytra zealandica (Coleoptera: Scarabaeidae), found in soil. Following ingestion of a lethal dose of bacteria, larvae of C. zealandica reduced feeding activity and movement. After approximately 4h infected larvae convulsed and regurgitated dark digestive fluid and expelled frass pellets leaving the midgut empty and the larva amber in appearance. In the initial stages of infection, ingested bacteria were mostly contained within the peritrophic membrane and expelled with the gut fluid or transferred into the hind gut. While few Y. entomophaga were associated with the midgut epithelial cells, by 24h cells were swelling and bursting with vesicles being expelled into the midgut lumen. By 48h, bacteria had entered the haemocoel and the midgut cells had further deteriorated. After 72h, the cellular remnants were totally detached from the basal membrane the infected insects were filled with bacteria and moribund or dead with septicaemia. Mortality was directly proportional to dose and time after infection. By applying a range of doses, the LD50 was determined as 2.9×10(4)Y. entomophaga per C. zealandica larva, with an LT50 of 2.94days for doses of>1×10(5) per larva. Ingestion of low doses of bacteria did not inhibit feeding activity but led more slowly to death. By time of death, Y. entomophaga had multiplied, approximately 500 fold, in the cadavers of the infected larvae. PMID:24291403

    Small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), is considered a serious threat to beekeeping in the Western Hemisphere, Australia, and Europe mainly due to larval feeding on honey, pollen, and brood of the European honeybee, Apis mellifera L. Control methods are limited for this pest. Studies were conducted to provide information on the radiobiology of small hive beetle and determine the potential for sterile insect releases as a control strategy. Adult males and females were equally sensitive to a radiation dose of 80 Gy and died within 5-7 d after treatment. In reciprocal crossing studies, irradiation of females only lowered reproduction to a greater extent than irradiation of males only. For matings between unirradiated males and irradiated females, mean reproduction was reduced by >99% at 45 and 60 Gy compared with controls, and no larvae were produced at 75 Gy. Irradiation of prereproductive adults of both sexes at 45 Gy under low oxygen (1-4%) caused a high level of sterility (>99%) while maintaining moderate survivorship for several weeks, and should suffice for sterile insect releases. Sterile insect technique holds potential for suppressing small hive beetle populations in newly invaded areas and limiting its spread. PMID:26470205

    ABSTRACT In spring 2002, ambrosia beetles (Coleoptera: Scolytidae) infested an intensively managed 22-ha tree plantation on the upper coastal plain of South Carolina. Nearly 3,500 scolytids representing 28 species were captured in ethanol-baited traps from 18 June 2002 to 18 April 2004. More than 88% of total captures were exotic species. Five species [Dryoxylon onoharaensum (Murayama), Euwallacea validus (Eichhoff), Pseudopityophthorus minutissimus (Zimmermann), Xyleborus atratus Eichhoff, and Xyleborus impressus Eichhoff]) were collected in South Carolina for the first time. Of four tree species in the plantation, eastern cottonwood, Populus deltoides Bartram, was the only one attacked, with nearly 40% of the trees sustaining ambrosia beetle damage. Clone ST66 sustained more damage than clone S7C15. ST66 trees receiving fertilization were attacked more frequently than trees receiving irrigation, irrigation_fertilization, or controls, although the number of S7C15 trees attacked did not differ among treatments. The study location is near major shipping ports; our results demonstrate the necessity for intensive monitoring programs to determine the arrival, spread, ecology, and impact of exotic scolytids.

    Calcrete aquifers in arid inland Australia have recently been found to contain the world's most diverse assemblage of subterranean diving beetles (Coleoptera: Dytiscidae). In this study we test whether the adaptive shift hypothesis (ASH) or the climatic relict hypothesis (CRH) is the most likely mode of evolution for the Australian subterranean diving beetles by using a phylogeny based on two sequenced fragments of mitochondrial genes (CO1 and 16S-tRNA-ND1) and linearized using a relaxed molecular clock method. Most individual calcrete aquifers contain an assemblage of diving beetle species of distantly related lineages and/or a single pair of sister species that significantly differ in size and morphology. Evolutionary transitions from surface to subterranean life took place in a relatively small time frame between nine and four million years ago. Most of the variation in divergence times of the sympatric sister species is explained by the variation in latitude of the localities, which correlates with the onset of aridity from the north to the south and with an aridity maximum in the Early Pliocene (five mya). We conclude that individual calcrete aquifers were colonized by several distantly related diving beetle lineages. Several lines of evidence from molecular clock analyses support the CRH, indicating that all evolutionary transitions took place during the Late Miocene and Early Pliocene as a result of aridification.

    Plagiodera versicolora (Laicharting, 1781) (Coleoptera: Chrysomelidae) is an important forest pest which damages many trees such as willow, poplar, and hazelnut. In order to find new microbes that can be utilized as a possible microbial control agent against this pest, we investigated the culturable bacterial flora of it and tested the isolated bacteria against P. versicolora larvae and adults. We were able to isolate nine bacteria from larvae and adults. The isolates were characterized using a combination of morphological, biochemical, and physiological methods. Additionally, we sequenced the partial sequence of the 16S rRNA gene to verify conventional identification results. Based on characterization studies, the isolates were identified as Staphylococcus sp. Pv1, Rahnella sp. Pv2, Rahnella sp. Pv3, Rahnella sp. Pv4, Rahnella sp. Pv5, Pantoea agglomerans Pv6, Staphylococcus sp. Pv7, Micrococcus luteus Pv8, and Rahnella sp. Pv9. The highest insecticidal activity against larvae and adults was obtained from M. luteus Pv8 with 50 and 40 % mortalities within 10 days after treatment, respectively. Extracellular enzyme activity of the bacterial isolates such as amylase, proteinase, lipase, cellulose, and chitinase was also determined. Consequently, our results show that M. luteus Pv8 might be a good candidate as a possible microbial control agent against P. versicolora and were discussed with respect to biocontrol potential of the bacterial isolates.

The studied material was obtained in four field campaigns carried out in the south of Spain and north of Morocco between 1997 and 2001 (Zaballos & Banda, 2000; Zaballos, 2005. In these campaigns abundant specimens of Typhlocharis (Coleoptera, Caraboidea, Trechidae were collected in different localities, the majority of them belonging to the species T. armata Coiffait, 1969. Their study and the comparison with the type series of this species allowed its complete redescription and clarification of its status within the genus. Contrary to what has been considered traditionally, the marginal umbilicate series of elytra in T. armata is composed of three, instead of four posterior setae. The taxonomical affinities of this species are established, the morphological weight of the umbilicate group of elytral setae as a lineage and species group defining character is discussed, and the theory of Jeanne (1973 about the relation between shortening of elytra and umbilicate series reduction with a decrease in body size is revised. The dispersal abilities are evaluated and a biogeographical explanation for the new distribution of the species is proposed.Esta primera parte sobre las especies de Typhlocharis vicariantes del Estrecho de Gibraltar está dedicada a Typhlocharis armata Coiffait, 1969; mientras que en un segundo artículo se tratará T. silvanoides Dieck, 1869.

    Full Text Available The establishment of taxonomic and geographical boundaries is a common problem when analysing clinal distributions. This is of particular concern when the assessment of intraspecific groupings is required for conservation management. The tiger beetle Cicindela lusitanica Mandl, 1935 (Coleoptera, Carabidae is a typical case in which two recognised subspecies are distributed in a clinal latitudinal fashion in the dune systems along the Atlantic coast of Portugal. This habitat is increasingly under threat, and conservation measures are needed. We investigated the validity of the two named subspecies, based on a re-analysis of elytral and genitalic measurements using multivariate analysis. We also analysed variation in mitochondrial Cytochrome Oxidase I gene for a total of six populations along the cline. Multivariate analysis supported the idea of a morphological cline and revealed a clear distinction of the southernmost population and also some degree of distinctiveness of the most northern populations, partially supporting the recognised subspecific ranking. The mtDNA analysis identified two main groups corresponding to northern and southern populations. Both sets of markers showed that variation within the C. lusitanica assemblage is complex, with the boundaries between morphological and mtDNA groups not in agreement. However, populations at either end of the distributional range are clearly distinct from each other, and should be considered as provisional units for conservation programmes.El reconocimiento de límites taxonómicos y geográficos de la variabilidad observada es un problema habitual cuando se analizan distribuciones clinales. Esto es particularmente problemático cuando se requiere la determinación de agrupamientos intraespecíficos para tomar medidas de conservación.

  11. Observations on sex ratio and behavior of males in Xyleborinus saxesenii Ratzeburg (Scolytinae, Coleoptera

    2010-09-01

    Full Text Available Strongly female-biased sex ratios are typical for the fungal feeding haplodiploid Xyleborini (Scolytinae, Coleoptera, and are a result of inbreeding and local mate competition (LMC. These ambrosia beetles are hardly ever found outside of trees, and thus male frequency and behavior have not been addressed in any empirical studies to date. In fact, for most species the males remain undescribed. Data on sex ratios and male behavior could, however, provide important insights into the Xyleborini’s mating system and the evolution of inbreeding and LMC in general. In this study, I used in vitro rearing methods to obtain the first observational data on sex ratio, male production, male and female dispersal, and mating behavior in a xyleborine ambrosia beetle. Females of Xyleborinus saxesenii Ratzeburg produced between 0 and 3 sons per brood, and the absence of males was relatively independent of the number of daughters to be fertilized and the maternal brood sex ratio. Both conformed to a strict LMC strategy with a relatively precise and constant number of males. If males were present they eclosed just before the first females dispersed, and stayed in the gallery until all female offspring had matured. They constantly wandered through the gallery system, presumably in search of unfertilized females, and attempted to mate with larvae, other males, and females of all ages. Copulations, however, only occurred with immature females. From galleries with males, nearly all females dispersed fertilized. Only a few left the natal gallery without being fertilized, and subsequently went on to produce large and solely male broods. If broods were male-less, dispersing females always failed to found new galleries.

    A field study was conducted to increase our understanding of diel activity patterns of Colaspis brunnea (F.) and Colaspis crinicornis Schaeffer (Coleoptera: Chrysomelidae) in key crop habitats. Within 24-h periods, C. brunnea was sampled in clover fields (primarily red clover, Trifolium pretense (L.), with some sweet clover, Melilotus officinalis (L.) Pallas, and downy brome, Bromus tectorum (L.)) and soybean, Glycine max (L.) Merrill, fields, using a sweep-net, while whole-plant-count sampling was used to monitor C. crinicornis densities in field corn, Zea mays (L.). Sweep-net captures of C. brunnea were significantly greater at night than during the day, suggesting possible vertical movement within the canopy during a 24-h period. Colaspis crinicornis densities on corn plants were fairly constant throughout a 24-h period, but beetle activity (e.g., walking, mating) was significantly greater at night than during the day. Results suggest that both Colaspis species may be exhibiting similar increases in activity at night that facilitates movement from more protected to more exposed areas within a habitat. It is unclear what mechanisms drive this diel pattern, but vegetation architecture and associated interactions with environmental conditions may play a role. Sweep-netting in clover or soybean fields and use of whole-plant-counts in cornfields were effective sampling methods for Colaspis adults. However, because activity and behaviors of Colaspis beetles were influenced by time of day in this study, use of a consistent sampling time within a diel period would be recommended for future population studies or integrated pest management decision-making.

    Mitochondrial genome organization in the Elateroidea superfamily (Coleoptera), which include the main families of bioluminescent beetles, has been poorly studied and lacking information about Phengodidae family. We sequenced the mitochondrial genomes of Neotropical Lampyridae (Bicellonycha lividipennis), Phengodidae (Brasilocerus sp.2 and Phrixothrix hirtus) and Elateridae (Pyrearinus termitilluminans, Hapsodrilus ignifer and Teslasena femoralis). All species had a typical insect mitochondrial genome except for the following: in the elaterid T. femoralis genome there is a non-coding region between NADH2 and tRNA-Trp; in the phengodids Brasilocerus sp.2 and P. hirtus genomes we did not find the tRNA-Ile and tRNA-Gln. The P. hirtus genome showed a ~1.6kb non-coding region, the rearrangement of tRNA-Tyr, a new tRNA-Leu copy, and several regions with higher AT contents. Phylogenetics analysis using Bayesian and ML models indicated that the Phengodidae+Rhagophthalmidae are closely related to Lampyridae family, and included Drilus flavescens (Drilidae) as an internal clade within Elateridae. This is the first report that compares the mitochondrial genomes organization of the three main families of bioluminescent Elateroidea, including the first Neotropical Lampyridae and Phengodidae. The losses of tRNAs, and translocation and duplication events found in Phengodidae mt genomes, mainly in P. hirtus, may indicate different evolutionary rates in these mitochondrial genomes. The mitophylogenomics analysis indicates the monophyly of the three bioluminescent families and a closer relationship between Lampyridae and Phengodidae/Rhagophthalmidae, in contrast with previous molecular analysis.

    Part of the exoskeleton of some wood-inhabiting insects is modified to form a mycangium, which is a specialized organ used to convey fungal spores or yeasts to their offspring. Although most stag beetles (Coleoptera: Lucanidae) are known to have female-specific mycangia and associated yeast symbionts, the evolutionary origin of the mycangium in this group remains unresolved. Here, we report the presence of a mycangium and associated yeast symbionts in the European horned stag beetle Sinodendron cylindricum (L.), which belongs to an ancestral clade of the Lucanidae. The mycangium of S. cylindricum is shown to be female-specific and have the same developmental origin as that of other stag beetles. A total of five yeast strains were isolated from adult mycangia and larval gut of S. cylindricum. Of these, we suggest that SICYAM1 is an undescribed yeast with taxonomic novelty, and have identified SICYLG3 as the xylose-fermenting yeast Scheffersomyces insectosa using nuclear ribosomal RNA and ITS sequences. The remaining three yeast strains, SICYAM2, SICYLG1, and SICYLG2, were assigned to the genus Sugiyamaella. Yeast density in the adult mycangium was lower than that of the more evolutionarily advanced stag beetles, the European Lucanus cervus (L.) and Dorcus parallelipipedus (L.), which were also examined in this study. No living yeasts were isolated from the adult guts. However, a third instar larva of S. cylindricum harbored 104–106 living yeasts in each gut region, which suggests that gut yeasts play an important role in these wood-feeding larvae. PMID:27432353

    Abscised cotton, Gossypium hirsutum L., fruit in field plots planted at different times were examined to assess adult boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), use of squares and bolls during 2002 and 2003 in the Lower Rio Grande Valley of Texas. Although boll abscission is not necessarily related to infestation, generally more bolls abscised than squares and abundances of fallen bolls were not related to the planting date treatments. During 2003, fallen squares were most abundant in the late-planted treatment. Although large squares (5.5-8-mm-diameter) on the plant are preferred for boll weevil oviposition, diameter of abscised squares is not a reliable measurement because of shrinkage resulting from desiccation and larval feeding. Fallen feeding-punctured squares and bolls were most abundant in late plantings but differences between fallen feeding-punctured squares versus fallen feeding-punctured bolls were found in only one treatment in 2003. During the same year, fallen oviposition-punctured squares were more numerous in the late-planted treatment than in the earlier treatments. Treatment effects were not found on numbers of oviposition-punctured bolls, but fallen oviposition-punctured squares were more common than bolls in the late-planted treatment compared with earlier treatments each year. Dead weevil eggs, larvae, and pupae inside fallen fruit were few and planting date treatment effects were not detected. Living third instars and pupae were more abundant in fallen squares of the late-planted treatment than in the earlier treatments and bolls of all three treatments. This study shows that fallen squares in late-planted cotton contribute more to adult boll weevil populations than bolls, or squares of earlier plantings. PMID:18330118

    Field trapping assays were conducted in 2009 and 2010 throughout western Michigan, to evaluate lures for adult emerald ash borer, A. planipennis Fairmaire (Coleoptera: Buprestidae). Several ash tree volatiles were tested on purple prism traps in 2009, and a dark green prism trap in 2010. In 2009, six bark oil distillate lure treatments were tested against manuka oil lures (used in 2008 by USDA APHIS PPQ emerald ash borer cooperative program). Purple traps baited with 80/20 (manuka/phoebe oil) significantly increased beetle catch compared with traps baited with manuka oil alone. In 2010 we monitored emerald ash borer attraction to dark green traps baited with six lure combinations of 80/20 (manuka/phoebe), manuka oil, and (3Z)-hexenol. Traps baited with manuka oil and (3Z)-hexenol caught significantly more male and total count insects than traps baited with manuka oil alone. Traps baited with manuka oil and (3Z)-hexenol did not catch more beetles when compared with traps baited with (3Z)-hexenol alone. When compared with unbaited green traps our results show that (3Z)-hexenol improved male catch significantly in only one of three field experiments using dark green traps. Dark green traps caught a high number of A. planipennis when unbaited while (3Z)-hexenol was seen to have a minimal (nonsignificant) trap catch effect at several different release rates. We hypothesize that the previously reported kairomonal attractancy of (3Z)-hexenol (for males) on light green traps is not as obvious here because of improved male attractancy to the darker green trap.

    Full Text Available Tropical mountain forests are hotspots of biodiversity hosting a huge but little known diversity of insects that is endangered by habitat destruction and climate change. Therefore, rapid assessment approaches of insect diversity are urgently needed to complement slower traditional taxonomic approaches. We empirically compare different DNA-based species delimitation approaches for a rapid biodiversity assessment of hyperdiverse leaf beetle assemblages along an elevational gradient in southern Ecuador and explore their effect on species richness estimates.Based on a COI barcode data set of 674 leaf beetle specimens (Coleoptera: Chrysomelidae of 266 morphospecies from three sample sites in the Podocarpus National Park, we employed statistical parsimony analysis, distance-based clustering, GMYC- and PTP-modelling to delimit species-like units and compared them to morphology-based (parataxonomic species identifications. The four different approaches for DNA-based species delimitation revealed highly similar numbers of molecular operational taxonomic units (MOTUs (n = 284-289. Estimated total species richness was considerably higher than the sampled amount, 414 for morphospecies (Chao2 and 469-481 for the different MOTU types. Assemblages at different elevational levels (1000 vs. 2000 m had similar species numbers but a very distinct species composition for all delimitation methods. Most species were found only at one elevation while this turnover pattern was even more pronounced for DNA-based delimitation.Given the high congruence of DNA-based delimitation results, probably due to the sampling structure, our study suggests that when applied to species communities on a regionally limited level with high amount of rare species (i.e. ~50% singletons, the choice of species delimitation method can be of minor relevance for assessing species numbers and turnover in tropical insect communities. Therefore, DNA-based species delimitation is confirmed as a

    Full Text Available Dung beetle assemblages (Coleoptera, Scarabaeinae in Atlantic forest fragments in southern Brazil. The beetles of the subfamily Scarabaeinae are important organisms that participate in the cycle of decomposition, especially in tropical ecosystems. Most species feed on feces (dung or carcasses (carrion and are associated with animals that produce their food resources. Dung beetles are divided into three functional groups: rollers, tunnelers and dwellers. This present work aims to study the diversity of dung beetle communities inhabiting fragments of the Atlantic Forest, with the purpose of describing the ecology of the species in southern Brazil. This study was conducted in the region of Campos Novos, in Santa Catarina, where twenty sites of Atlantic forest fragments were sampled. Samplings of dung beetles were conducted using 200 pitfall traps, of which 100 were baited with human feces and another 100 with carrion. Size and environmental complexity were also measured for each forest fragment. A total of 1,502 dung beetles, belonging to six tribes, 12 genera and 33 species, were collected. Results of the Levin's index of niche breadth indicated that 11 species were categorized as being coprophagous, ten as generalists, and two as necrophagous. Most species are tunnelers (19, nine of rollers and four of dwellers. The great diversity of Scarabaeinae in the region of Campos Novos, including several rare species, adds important data to the Scarabaeinae fauna in the central-western region of Santa Catarina. It may also help choosing priority areas for conservation in the region, where human impact, with large areas of monoculture, increasingly threatens the fragments of Mixed Ombrophilous Forest.

    The toxicity of organic plant extracts to Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) was assessed for three tropical plant species: branches, leaves, and seeds of Annona montana (Annonaceae), branches of Aristolochia paulistana (Aristolochiaceae), and leaves and branches of Casearia sylvestris (Salicaceae). The screening assay resulted that the extracts of A. montana seeds obtained with hexane (LC50 = 534.75 mg kg(-1) and LT50 = 6.10 days) and with dichloromethane (LC50 = 424.67 mg kg(-1) and LT50 = 5.03 days) were the most promising treatments, followed by the extract prepared from A. montana leaves with hexane (LC50 = 837.70 mg kg(-1) and LT50 = 4.90 days). Moreover, extracts (at 1,500 mg kg(-1)) prepared from C. sylvestris branches with dichloromethane and A. paulistana with hexane caused significant mortality (37% and 41.5%, respectively) beyond sublethal effects on S. zeamais. Therefore, based on the biological assays, extraction yield, and evaluation of the chromatographic profile of the crude extracts by TLC, the hexane extract of A. montana seeds was selected and fractioned using liquid-liquid partitioning. The hydroalcoholic fraction caused mortality of 55.5%, significantly superior to dichloromethane fraction, which caused 35.5% of mortality. Chemical analyses ((1)H NMR, HPLC, and TLC) were performed, and the results showed the presence of alkaloids and acetogenins in both active fractions, which have been associated with bioactivity. Therefore, extracts prepared from A. montana seeds (especially) is an interesting source of new compounds with promising grain-protectant properties. PMID:27193958

    Experiments were conducted to examine how several key factors affect population growth of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae). Laboratory experiments were conducted to examine effects of food quantity and temperature on reproduction of cohorts of young A. tumida adults (1:1 sex ratio) housed in experimental arenas. Daily numbers and total mass of larvae exiting arenas were highly variable within treatment. Either one or two cohorts of larvae were observed exiting the arenas. Food quantity, either 10 g or 20 g, did not significantly affect the number of larvae exiting arenas at 32°C, but did at 28°C; arenas provided 20 g food produced significantly more larvae than arenas provided 10 g. Temperature did not affect the total mass of larvae provided 10 g food, but did affect larval mass provided 20 g; beetles kept at 28°C produced more larval mass than at 32°C. Field experiments were conducted to examine A. tumida reproductive success in full strength bee colonies. Beetles were introduced into hives as egg-infested frames and as adults, and some bee colonies were artificially weakened through removal of sealed brood. Efforts were unsuccessful; no larvae were observed exiting from, or during the inspection of, any hives. Possible reasons for these results are discussed. The variability observed in A. tumida reproduction even in controlled laboratory conditions and the difficulty in causing beetle infestations in field experiments involving full colonies suggest that accurately forecasting the A. tumida severity in such colonies will be difficult.

    To compare resistance to small hive beetles (Coleoptera: Nitidulidae) between Russian and commercial Italian honey bees (Hymenoptera: Apidae), the numbers of invading beetles, their population levels through time and small hive beetle reproduction inside the colonies were monitored. We found that the genotype of queens introduced into nucleus colonies had no immediate effect on small hive beetle invasion. However, the influence of honey bee stock on small hive beetle invasion was pronounced once test bees populated the hives. In colonies deliberately freed from small hive beetle during each observation period, the average number of invading beetles was higher in the Italian colonies (29 +/- 5 beetles) than in the Russian honey bee colonies (16 +/- 3 beetles). A similar trend was observed in colonies that were allowed to be freely colonized by beetles throughout the experimental period (Italian, 11.46 +/- 1.35; Russian, 5.21 +/- 0.66 beetles). A linear regression analysis showed no relationships between the number of beetles in the colonies and adult bee population (r2 = 0.1034, P = 0.297), brood produced (r2 = 0.1488, P = 0.132), or amount of pollen (P = 0.1036, P = 0.295). There were more Italian colonies that supported small hive beetle reproduction than Russian colonies. Regardless of stock, the use of entrance reducers had a significant effect on the average number of small hive beetle (with reducer, 16 +/- 3; without reducer, 27 +/- 5 beetles). However, there was no effect on bee population (with reducer, 13.20 +/- 0.71; without reducer, 14.60 +/- 0.70 frames) or brood production (with reducer, 6.12 +/- 0.30; without reducer, 6.44 +/- 0.34 frames). Overall, Russian honey bees were more resistant to small hive beetle than Italian honey bees as indicated by fewer invading beetles, lower small hive beetle population through time, and lesser reproduction.

    Endophytic fungi belonging to the genus Neotyphodium, confer resistance to infected host grasses against insect pests. The effect of host species, and endophtye species and strain, on feeding and survival of the corn flea beetle, Chaetocnema pulicaria Melsheimer (Coleoptera: Chrysomelidae) was investigated. The grass-endophyte associations included natural and artificially derived associations producing varying arrays of common endophyte-related alkaloids or alkaloid groups, peramine, lolitrem B, ergovaline, and the lolines. Preference and nonpreference tests showed that C. pulicaria feeding and survival were reduced by infection of tall fescue with the wild-type strain of N. coenophialum, the likely mechanism being antixenosis rather than antibiosis. In the preference tests, endophyte and host species effects were observed. Of the 10 different Neotyphodium strains tested in artificially derived tall fescue associations, eight strongly deterred feeding by C. pulicaria, whereas the remaining two strains had little or no effect on feeding. Infection of tall fescue with another fungal symbiont, p-endophyte, had no effect. Perennial ryegrass, Lolium perenne L., infected with six strains of endophyte, was moderately resistant to C. pulicaria compared with endophyte-free grass, but four additional strains were relatively inactive. Six Neotyphodium-meadow fescue, Festuca pratensis Huds., associations, including the wild-type N. uncinatum-meadow fescue combination, were resistant, whereas three associations were not effective. Loline alkaloids seemed to play a role in antixenosis to C. pulicaria. Effects not attributable to the lolines or any other of the alkaloids examined also were observed. This phenomenon also has been reported in tests with other insects, and indicates the presence of additional insect-active factors. PMID:21510220

    This study was conducted to determine the efficacy of local natural products against the beetle, Callosobruchus chinensis L. (Coleoptera: Bruchidae), in stored chickpea Cicer arietinum L. (Fabaceae) in Chitwan, Nepal. Five natural products and one synthetic pesticide (Malathion) and two storage regimes (aluminum sheet bin vs. jute bags with plastic lining) were tested for their effect on stored pulse with respect to damage by C. chinensis. The five natural products included Xanthoylum armatum DC (Rutaceae) fruit powder, Acorus calamus L. (Araceae) rhizome powder, Cinnamom camphora L. (Lauraceae) balls, oil of Sesamum indicum L. (Pedaliaceae), and leaf powder of Azadirachta indica A. Juss. (Meliaceae). Treatments of stored pulses with natural products or with Malathion all caused significantly higher mortality of C. chinensis at 15 d after treatment (DAT) than stored pulses receiving no treatments. The balls of C. camphora, rhizome powder of A. calamus and sesame oil outperformed all other treatments, including the Malathion at 45 and 75 DAT and resulted in significantly reduced damage or deterioration of stored pulses compared with other treatments. Storage regimes performed similarly, although the jute bags did protect seed integrity for some treatments. Our results indicate that incorporating these natural products into stored pulses can protect the seeds from C. chinensis for up to two generations, something that Malathion cannot do. These products are readily available to most farmers in the region and their use will lead to 1) reduction of losses to significant stored product pests, and 2) a reduction of contamination of foodstuffs and the environment by synthetic pesticides like Malathion.

    Ten insecticides representing seven chemical groups were applied at various concentrations topically by using a Potter Spray Tower to evaluate their relative toxicities on the European wireworm Agriotes obscurus L. (Coleoptera: Elateridae). Wireworms were stored at 15 degrees C after exposure to organophosphate (OP) (chlorpyrifos, diazinon), pyrethroid (tefluthrin), thianicotinoid (thiamethoxam, clothianidin), chloronicotinoid (imidacloprid, acetamiprid), phenyl pyrazole (fipronil), organochlorine (lindane), and spinosyn (spinosad) insecticides, and their postapplication health was evaluated weekly for up to 301 d. LC50, LC90, LT50, and LT90 values were calculated for each chemical except acetamiprid, and compared with those of lindane, clothianidin, and chlorpyrifos. Wireworms exposed to OPs died or recovered more quickly (LT50 < 20 d, LT90 < 50 d), than those exposed to all other insecticides tested except tefluthrin (LT50 = 25.5 d, LT90 = 66.5 d). Wireworms exposed to sublethal concentrations of all neonicotinoids quickly became moribund after application but made a full recovery. Wireworms exposed to fipronil at concentrations near the LC90 value showed no intoxication symptoms for up to 35 d, and they did not recover after symptoms developed. For each chemical, increasing the concentration increased the time required for wireworms to recover but decreased the time required to kill wireworms. Fipronil was highly toxic to wireworms (LC50 = 0.0001%), but acetamiprid (LC50 = 1.82%), imidacloprid (LC50 = 0.83%), tefluthrin (LC50 = 0.23%), diazinon (LC50 = 0.54%), and spinosad (LC50 = 0.51%) were not. The toxicity of both clothianidin (LC50 = 0.07%) and thiamethoxam (LC50 = 0.17%) were similar to those oflindane (LC50 = 0.06%) and chlorpyrifos (LC50 = 0.10%). PMID:18459401

    The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is known as one of the mostserious pests of grains in many parts of the world. In this study, the effect of nine barley cultivars (‘Bahman’,‘CB-84-10’, ‘Fajr 30’, ‘Makuyi’, ‘Nosrat’, ‘Yousof’, ‘13A1’, ‘18A1’, and ‘19 A1’) and a wheat cultivar (‘MV17’, as a control) was determined on the nutritional indices and digestive enzymatic activity of T. granarium at 33 6 1C,relative humidity of 6565%, and a photoperiod of 14:10 (L:D) h. The highest and lowest values of larval weight gain of sixth instar were detected on wheat (0.757±0.068 mg) and cultivar Bahman (0.342±0.071 mg). Also, T. granarium larvae fed on cultivar Bahman had the lowest value of efficiency of conversion of ingested food(10.90±2.09%) as compared with wheat and other barley cultivars. Also, the highest midgut amylolytic and proteolytic activities of sixth instar were on cultivar Bahman (0.364±0.024 mU/mg and 80.54±1.73 U/mg, respectively)and the lowest activities were on cultivar Nosrat (0.043±0.004 mU/mg and 7.15±0.01 U/mg, respectively).It is concluded that barley cultivar Bahman was the most unsuitable host for feeding of T. granarium.

    Functional response of the predator Chilocorus cacti (Linnaeus) (Coleoptera: Coccinellidae) on five densities of Dactylopius opuntiae (Cockerell) (Hemiptera: Dactylopiidae) female adults was assessed under laboratory conditions. The searching efficiency of C. cacti significantly decreased as prey density increased. The logistic regression for the predator had a negative and significant linear parameter indicating a type II functional response. Non-linear regression for Holling predator equation estimated a handling time of 1.79 ± 0.129 h and attack rate coefficient of 0.1003 ± 0.030. Most of this handling time was because the predator spent a lot of time removing the waxy coating that protects adult females of D. opuntiae. Chilocorus cacti consumes females of D. opuntiae in their reproductive stage; therefore, it could be an effective natural enemy to suppress or regulate low density populations of D. opuntiae, preventing them to reach high densities.

    The LC/sub 50/ values for malathion-resistant (PAK) and organo-50 phosphate-susceptible (FSS-II) strains of red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) adult beetles were determined through filter paper impregnated method against azadirachtin (Nimbokil 60 EC) and polychlorinated petroleum hydrocarbon (Tenekil 100 EC). The LC values of these insecticides were worked out as 12830 and 50 9331 ppm for azadirachtin and 5148 and 4047 ppm for Tenekil 100 EC against PAK and FSS-II strains, respectively. The results revealed that polychlorinated petroleum hydrocarbon was more toxic than the azadirachtin. Furthermore, both the insecticides were equally toxic to the adult beetles of T. castaneum as the difference was non-significant because of overlapping 95% FLs to LC./sub 50/. (author)

    Developmental rate and survivorship of small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), life stages were measured across different temperatures (21, 25, 28, 32 and 35 degrees C) and diets, which included natural and artificial pollen, honey, and bee pupae. Temperature affected hatch success, time to hatching, and larval growth. Eggs hatched in 61 h at 21 degrees C but in Beetles lived longer at 28 degrees C or lower but produced the most eggs per female, regardless of diet, at 32 degrees C. Beetle density influenced fecundity: beetles kept at three pairs per vial laid 6.7 times more eggs per female than those kept as single pairs. Overall, beetles fared best at 28-32 degrees C with mortality of all stages highest at 35 degrees C. PMID:21735891

    2000-06-01

    The effect of habitat fragmentation on genetic differentiation among local populations of the fungivorous beetle Bolitophagus reticulatus (Coleoptera: Tenebrionidae) was studied in two contrasting landscapes: one heavily fragmented with forest fragments of variable size surrounded by inhabitable agricultural fields, the other an old forest providing a continuous habitat. The genetic structure of the beetle within each of the two contrasting areas was investigated by means of protein electrophoresis, screening four polymorphic loci in 20 populations from each area. In both areas there were significant genetic differences among local populations, but on average differentiation in the fragmented area was three times greater than in the continuous one, strongly indicating a genetic isolation effect of habitat fragmentation. These genetic results are in accordance with previous studies on dispersal in this species. PMID:10886382

    The larger black flour beetles, Cynaeus angustus (LeConte) (Coleoptera: Tenebrionidae), feeds on saprophytic fungi found in gin trash piles and occasionally becomes a nuisance pest in adjacent homes and businesses. The potential of Steinernema carpocapsae 'NY 001,' as a potential control agent of larger black flour beetle under experimental conditions was examined with particular reference to the importance of soil moisture content. Without prospects of insecticides being labeled for control of larger black flour beetle in gin trash, the data presented here support further research into applications of entomopathogenic nematodes underneath gin trash piles as a way to minimize risk of larger black flour beetle populations causing nuisance to nearby homes and businesses.

    Full Text Available Abstract Background The harlequin ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae is native to central and eastern Asia and was purposely introduced into Europe to control aphids. While it proved to be a good biological control agent, its rapid spread and buildup of large populations made it a nuisance, since it overwinters in homes, emits unpleasant odors, stains fabrics, occasionally bites humans and feeds on apples, pears and grapes. Aside from the above, the ravenous appetite of H. axyridis results in their consumption of harmless native insects, including even other ladybird beetles. A study of the natural enemies of H. axyridis in Denmark revealed the presence of nematodes. The present study describes this nematode parasite and discusses aspects of its development and ecology. Methods Adult harlequin ladybird beetles were collected from March to November from four localities in Copenhagen on different plant species. In addition, groups of last-instar larvae and pupae (n = 50 were examined for the presence of nematodes. Living and recently dead nematodes were removed from adult H. axyridis in 0.5% saline solution, the nematodes were then heat killed (at 75C, fixed in 5% formalin and transferred to glycerin on slides for further examination and measurements. Results A new species of Allantonematidae (Tylenchida, Parasitylenchus bifurcatus n. sp., is described from adults of the harlequin ladybird, Harmonia axyridis in Denmark. The new species is characterized by a straight stylet lacking basal thickenings, a bursa and a forked tail tip in the vermiform (infective females and juvenile males. The new species is compared with P. coccinellinae previously described from ladybird beetles in France. Parasitism resulted in depletion of the fat body and partial or complete atrophy of the reproductive organs of the beetles. Infections occurred throughout the year with rates of parasitism reaching up to 35%. The rate increased to 60

The LC50 values estimated under direct immersion method ranged from 1.7 x 10(5) to 1.9 x 10(7), 3.5 x 10(4) to 5.3 x 10(5), and 4.1 x 10(3) to 2.9 x 10(5) conidia/ml for B. basissiana and from 3.2 x 10(6) to 1.1 x 10(7), 4.5 x 10(3) to 4.5 x 10(5), and 1.4 x 10(2) to 1.2 x 10(5) conidia/ml for M. anisopliae at 4, 5, and 6 d after treatment, respectively. By days 5 and 6, B. bassiana GHA outperformed all other isolates tested except ARSEF 7234, followed by ARSEF 7152, 6393, and 7180. Significant concentration-mortality response was also observed for two B. bassiana GHA formulations, BotaniGard ES and Mycotrol O, and M. anisopliae F52 when insects were treated through foliar exposure. The LC50 values ranged from 114.5 to 309.6, 18.4 to 797.3, and 345.3 to 362.0 conidia/cm2 for BotaniGard, Mycotrol, and M. anisopliae F52, respectively. Based on the results of these bioassays, the efficacy of both B. bassiana GHA formulations and M. anisopliae F52 were similar against adult A. planipennis. The potential use of entomopathogenic fungi for management of A. planipennis in North America is discussed. PMID:16937660

    Full Text Available The Chrysomelidae (Coleoptera is a highly speciose family that has been poorly studied at the regional level in Mexico. In the present study, we estimated species richness and diversity in oak-pine forest, Tamaulipan thorny scrub and in tropical deciduous forests in Peregrina Canyon within the Altas Cumbres Protected Area of the northeastern state of Tamaulipas, Mexico. Sampling of Chrysomelidae consisted of five sweep net samples (200 net sweeps within each of three sites during four sample periods: early dry season, late dry season, early wet season, and late wet season. Species were identified and total numbers per species were recorded for each sample. A total of 2,226 specimens were collected belonging to six subfamilies, 81 genera and 157 species of Chrysomelidae from the study area. Galerucinae was the most abundant subfamily with 1,828 specimens, representing 82.1% of total abundance in the study area. Lower abundance was recorded in Cassidinae (8.5%, Eumolpinae (3.6%, Cryptocephalinae (2.2%, Chrysomelinae (2.2%, and finally Criocerinae (1.3%. The highest species richness was also presented in the subfamily Galerucinae with 49% of the total obtained species followed by Cassidinae (20%, Cryptocephalinae (9.7%, Eumolpinae (9.7%, Chrysomelinae (6.5% and Criocerinae (5.2%. The most common species were Centralaphthona fulvipennis Jacoby (412 individuals, Centralaphthona diversa (Baly (248, Margaridisa sp.1 (219, Acallepitrix sp.1 (134, Longitarsus sp.1 (104, Heterispa vinula (Erichson (91, Epitrix sp.1 (84 and Chaetocnema sp.1 (72. Twenty-two species were doubletons (1.97% of total abundance and 52 were singletons (2.33%. The estimated overall density value obtained was 0.0037 individuals/m2. The greatest abundance and density of individuals were recorded at the lowest elevation site. However, alpha diversity increased with increasing altitude. Similarity values were less than 50% among the three sites indicating that each site had distinct

    为揭示秦岭地区耶屁步甲(Pheropsophus jessoensis Morawitz)种群的谱系地理结构,对秦岭2个地理区内25个耶屁步甲地理种群的184个个体的线粒体细胞色素氧化酶亚基Ⅰ (mtCoI)基因部分序列进行了分析.在879 bp个碱基中,共检测到55个变异位点,定义了67个单倍型.单倍型多样性(Hd=0.9550)较高,核苷酸多样性(Pi=0.0049)较低.东、西秦岭地区间和25个地理种群间的平均Kimura 2-parameter (K2P)遗传距离都很小,介于0.0026 ~0.0072.分子变异(AMOVA)和嵌套进化枝谱系地理学分析(NCPA)表明,耶屁步甲的分子变异主要来源于种群内个体间,而东、西两个地区间没有明显的谱系地理结构.错配分布和中性检验分析表明,单倍型之间存在一定的地理关联,距离隔离的限制性基因流以及快速或持续的种群扩张是造成该种目前遗传特征的主要因素.对秦岭地区的耶屁步甲进行种群动态推断,最近一次扩张时间发生0.05 ~ 0.23 Ma,处于更新世晚期,认为可能是第四纪冰期气候的反复变化导致了耶屁步甲现今的遗传格局.%In order to understand the phylogeographic structure of Pheropsophus jessoensis Morawitz in the Tsinling Mountains,a fragment with 789 bp from the mtCoI gene was sequenced for the 184 P.jessoensis individuals from 25 geographical populations belonging to two geographic areas.A total of 55 polymorphic sites were found,and 67 haplotypes were identified.The haplotype diversity was high (Hd =0.9550),while the nucleotide diversity was relatively low (Pi =0.0049).The Kimura 2-parameter (K2P) genetic distance of the P.jessoensis between west Tsinling population and east Tsinling population or among the 25 populations was small,with the values ranged from 0.0026 to 0.0072.The analysis of molecular variance (AMOVA) and the nested clade phylogeographical analysis (NCPA) revealed the significant genetic subdivision among the individuals within populations,but there existed no remarkable phylogeographic structure between the eastern part and the western part of Tsinling Mountains.The NCPA showed certain geographical association of haplotypes.The results from mismatch distribution and neutrality tests suggested that the present complex genetic pattern of P.jessoensis in Tsinling Mountains was resulted from the restricted gene flow with isolation by distance,and from the sudden or contiguous range expansion.The demographic history analysis revealed that this species could have experienced a relatively recent population expansion occurring in the later Pleistocene (0.05-0.23 Ma).The climatic oscillations during this period might have affected the geographical isolation and genetic differentiation of P.jessoensis in this area.

    The parasitoid, Microctonus aethiopoides Loan (Hymenoptera: Braconidae) was introduced into New Zealand in 1982 to control the alfalfa pest, Sitona discoideus Gyllenhal (Coleoptera: Curculionidae). Studies have shown that a number of nontarget weevil species are attacked in the field by this parasitoid. A field study was carried out to investigate nontarget parasitism by M. aethiopoides over an altitudinal sequence from the target host habitat (alfalfa) into native grassland. Three locations were selected for the study, and at each, the alfalfa growing in the valley floor was sampled annually for parasitism of the target pest that ranged between 17 and 78%. At progressively higher altitudes, three further grassland sites at each location were sampled monthly during spring to autumn for up to 6 yr. Weevil densities were estimated, species identified, and dissections carried out to determine reproductive status and parasitism. Almost 12,000 weevils were collected during the study, which were identified as 36 species in total from the three locations. Eight weevil species were found to be parasitized, including S. discoideus, the target host that was found at all sites. Parasitism of nontarget species was approximately 2% overall but varied with location, site, and season. Substantial nontarget parasitism was found at only one of the locations, with up to 24% parasitism of a native weevil, Nicaeana fraudator Broun (Coleoptera: Curculionidae), recorded. Another species, Irenimus egens (Broun) (Coleoptera: Curculionidae), was also found at this location at similar population densities but was attacked far less by M. aethiopoides. Results are discussed in relation to weevil phenology. PMID:17716473

    Full Text Available Occurrence of adults and biological aspects of Geniates borelli Camerano (Coleoptera, Scarabaeidae, Rutelinae in Aquidauana, Mato Grosso do Sul, Brazil. Due to the importance of Geniates borelli Camerano as a pest in many crops, studies were developed at Universidade Estadual de Mato Grosso do Sul, Aquidauana campus, MS, Brazil. Adults were collected with a light trap from January 2006 to December 2007. 3,320 adults were collected, and the highest quantities were obtained in October 2006 and November 2007, with 1,548 and 802 adults recorded, respectively. Collected adults were kept in plastic containers with soil and Brachiaria decumbens seedlings for oviposition. 535 eggs measuring 2.30 × 1.60 mm were obtained. As the embryonic development progressed, eggs increased in size to 3.00 × 2.70 mm, and this change occurred between 6 and 10 days after oviposition. The embryonic period lasted 17.9 days. The first, second, and third instars lasted 37.6, 49.7, and 74 days, respectively. The prepupal stage lasted 65.9 days and the pupal stage lasted an average of 18.5 days. The biological cycle is completed in 315.8 days, which characterizes the species as univoltine. The average longevity of females was 35.4 days and 28.5 days for males.

    The phylogenetic relationships of thirteen Diabrotica (representing virgifera and fucata species groups) and two outgroup Acalymma beetle species (Coleoptera: Chrysomelidae) were inferred from the phylogenetic analysis of a combined data set of 1323 bp of mitochondrial DNA (mtDNA) cytochrome oxidase subunit 1 (COI) and the entire second internal transcribed spacer region (ITS-2) of nuclear ribosomal DNA of 362 characters. Species investigated were D. adelpha, D. balteata, D. barberi, D. cristata, D. lemniscata, D. longicornis, D. porracea, D. speciosa, D. undecimpunctata howardi, D. u. undecimpunctata, D. virgifera virgifera, D. v. zeae, D. viridula, and outgroup A. blandulum and A. vittatum. Maximum parsimony (MP), minimum evolution (ME), and maximum likelihood (ML) analyses of combined COI and ITS-2 sequences clearly place species into their traditional morphological species groups with MP and ME analyses resulting in identical topologies. Results generally confer with a prior work based on allozyme data, but within the virgifera species group, D. barberi and D. longicornis strongly resolve as sister taxa as well as monophyletic with the neotropical species, D. viridula, D. cristata and D. lemniscata also resolve as sister taxa. Both relationships are not in congruence with the prior allozyme-based hypothesis. Within the fucata species group, D. speciosa and D. balteata resolve as sister taxa. Results also strongly supported the D. virgifera and D. undecimpunctata subspecies complexes. Our proposed phylogeny provides some insight into current hypotheses regarding distribution status and evolution of various life history traits for Diabrotica. PMID:11520353

    Full Text Available New records of Osmoderma eremita (Scopoli, 1763 (Coleoptera: Scarabaeidae: Cetoniinae are reported for Abruzzo (Italy, together with a review of its distribution in this region. O. eremita is a saproxylic beetle dependent on the presence of hollow deciduous trees with abundant wood mould in their cavities. The major threats for the species are habitat loss and fragmentation. EU Habitats Directive requests to the member States its protection and the monitoring of its conservation status. Detection of its occurrence is the first step to protect the species. The surveys have been carried out in ten sites of Abruzzo by using black cross-windows traps baited with specific pheromone. The species has been recorded for the first time in the Sant’Antonio forest and its presence is confirmed in the Peligna Valley, after a decade. The populations seem to be confined to small patches of suitable habitats. At local level, the abandonment of the pollarding practice (willow and beech forests and the use of pollarded trees as biomass for fuel are the major threats for this species. Indeed some key actions, such as the protection of old hollow trees and the continuation of pollarding practice in rural landscape, could be key factors for the conservation strategies of the species in the study area.

    Dozens of arthropod species are known to feed and breed in the necrotic tissues (rots) of columnar cacti in the Sonoran Desert. Because the necrotic patches are ephemeral, the associated arthropods must continually disperse to new cacti and therefore the populations of any given species are expected to show very little local genetic differentiation. While this has been found to be true for the cactophilic Drosophila, the evolutionary histories and characteristics of other arthropods inhabiting the same necrotic patches, especially the beetles, have yet to be examined. Here we used nucleotide sequence data from segments of the mitochondrial 16S rRNA and cytochrome c oxidase subunit I (COI) genes to examine population structure and demographic history of three sympatric beetle species (Coleoptera: Histeridae and Staphylinidae) collected on senita cactus (Lophocereus schottii) from six widely-separated localities on the Baja California peninsula of northwestern Mexico. Two histerids, Iliotona beyeri and Carcinops gilensis, and an unidentified staphylinid, Belonuchus sp., showed little or no population structure over a broad geographic area on the peninsula, consistent with the prediction that these beetles should show high dispersal ability. Demographic tests revealed varying levels of historical population expansion among the beetle species analyzed, which are discussed in light of their ecologies and concurrent biogeographic events. Additionally, phylogenetic analyses of COI sequences in Carcinops collected on a variety of columnar cacti from both peninsular and mainland Mexico localities revealed several species-level partitions, including a putative undescribed peninsular species that occurred sympatrically with C. gilensis on senita.

    Root-feeding grubs (Coleoptera: Scarabaeidae) were sampled from damaged areas of 61 irrigated roughs on 32 Kentucky golf courses to determine species composition and natural enemy incidence, the first such survey in the United States' transitional turfgrass climatic zone. Masked chafers (Cyclocephala lurida Bland and C. borealis Arrow) and Japanese beetle (Popillia japonica Newman) accounted for ≈73 and 26% of grubs found in an autumn survey, with Cyclocephala spp. predominating at most sites, although mixed infestations were common. Only a few Phyllophaga spp., and no exotic species other than P. japonica were found. Cyclocephala spp. also predominated in seasonal and statewide surveys regardless of whether a course had cool- or warm-season grass fairways. Pathogenic bacteria, Paenibacillus and Serratia spp., and the autumn-active parasitoid Tiphia pygidialis Allen were the main enemies associated with Cyclocephala spp. Predominant enemies of P. japonica were Paenibacillus, Serratia, and Metarhizium spp. in autumn, and eugregarines, Stictospora sp. (probably S. villani Hays and Clopton) and Tiphia vernalis Rohwer in spring. Entomopathogenic nematodes and the microsporidian Ovavesicula popilliae Andreadis & Hanula were nearly absent in our samples. No predictive relationships were found between soil parameters and proportionate abundance of Cyclocephala or P. japonica, or with natural enemy incidence at particular sites. Although incidence of individual enemies was generally low (hosts' prolonged development they may take a significant toll on grub populations. PMID:22182549

    Full Text Available The Yunnan pine shoot beetle, Tomicus yunnanensis Kirkendall and Faccoli (Coleoptera: Scolytinae is an important pest of Yunnan pine (Pinus yunnanensis Franch in China. Experiments with host log baits were done to develop a pest monitoring system using host tree kairomone. Five Yunnan pine logs (each 10–15 cm diam. × 30-cm long in a trap-log bundle were treated by peeling periderm (outer bark off to expose the phloem, and half of each log was covered with sticky adhesive to capture any attracted adult beetles. Significantly, more beetles were attracted and caught on the periderm-peeled logs (ca 30 beetles/m2 log surface/day than on untreated control logs with adhesive (ca 2.5/m2/day. No significant differences were observed between catches on logs taken from lower or upper halves of Yunnan pines. T. yunnanensis flies mostly during the afternoon according to trap catches throughout the day. Attraction to the periderm-peeled logs decreased considerably when they were peeled further to remove the phloem, indicating phloem volatiles play a role in selection of the host by the beetle. The readily-available log baits appear useful for monitoring pine shoot beetle populations in integrated pest management programs.

    Surveys on Coccinellidae (Coleoptera) in Sete Lagoas city, Minas Gerais state, Brazil, indicated the parasitism of adults of the species Coleomegilla maculata De Geer, 1775, Eriopis connexa (Germar, 1824) and Olla v-nigrum (Mulsant, 1866), by Dinocampus coccinellae (Schrank, 1802) (Hymenoptera; Braconidae: Euphorinae). Since then, the parasitoid have been maintained in its original hosts at the Insect Rearing Laboratory - LACRI of the Brazilian Agricultural Research Institution - Embrapa Milho e Sorgo. Besides the citation of occurrence in Brazil, this work also indicates the parasitoid preference for C. maculata (70% of parasitism), followed by O. v-nigrum (43.3% of parasitism) and E. connexa (36.7% of parasitism). Total life cycle of D. coccinellae was longer on C. maculata (32.4 ± 0.48 days), compared to O. v-nigrum (29.5 ± 0.49 days) and E. connexa (27.8 ± 0.4 days). Due to the relatively high percentage of field parasitism, D. coccinellae can reduce the efficiency of biological pest control by Coccinellidae predators especially in the case of C. maculata.

    Transgenic crops that produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are widely planted to manage pest insects. One of the primary pests targeted by Bt corn in the United States is western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae). Cry3Bb1 corn for management of western corn rootworm was commercialized in 2003, and beginning in 2009, populations of western corn rootworm with field-evolved resistance to Cry3Bb1 corn were found in Iowa. Here we quantify the magnitude, inheritance, and fitness costs of resistance to Cry3Bb1 corn in two strains (Hopkinton and Cresco) derived from field populations that evolved resistance to Cry3Bb1 corn. For Hopkinton, we found evidence for complete resistance to Cry3Bb1 corn and nonrecessive inheritance. Additionally, no fitness costs of Cry3Bb1 resistance were detected for Hopkinton. For Cresco, resistance was incomplete and recessive, and we detected fitness costs affecting developmental rate, survival to adulthood, and fecundity. These results suggest that variation may exist among field populations in both the inheritance and accompanying fitness costs of resistance. To the extent that field populations exhibit nonrecessive inheritance and a lack of fitness cost, this will favor more rapid evolution of resistance than would be expected when resistance is functionally recessive and is accompanied by fitness costs.

  20. Effects of irradiated diet on longevity and prolificity of successive generations of Zabrotes subfasciatus (Boheman, 1833) (Coleoptera, Bruchidae)

    International Nuclear Information System (INIS)

    The study was done in the laboratory of Entomology of the Centro de Energia Nuclear na Agricultura (CENA), University of Sao Paulo, in Piracicaba, State of Sao Paulo, Brazil. This research was carried out to observe the effect of irradiated beans (Phaseolus vulgaris, (L.), cultivar Rosinha) on the longevity and prolificity of Zabrotes subfasciatus (Boheman, 1833) (Coleoptera, Bruchidae). The first part of the study included the rearing of five generations of Zabrotes subfasciatus which were fed with irradiated beans (0, 10, 20, 100 e 200 krad, with a dose rate of approximately 70 krad/h). The second one consisted of growth of seven generations on irradiated beans (0, 100, 500, 1500 and 3000 krad, with a dose rate of approximately 70 krad/h). The data were obtained through daily countings of insect birth and death rates. It was concluded that irradiation modified the nutritional quality of beans, affecting the development of Zabrotes subfasciatus. This effect was studied through the longevity and prolificity, which were altered as compared with the control, once they were higher for the dosis of 1500 and 3000 krad. (author)

    The effect of different bean varieties on the performance of the bruchid beetle Zabrotes subfasciatus Boheman (Coleoptera: Bruchidae), was determined by using wild and cultivated seeds of the genus Phaseolus. Results showed that the quality of the host plant affected the performance and the oviposition behavior of female beetles. Overall, bruchid performance was higher on cultivated seeds than on wild seeds. It was also found that the oviposition behavior and the performance of their offspring differed between females that originated from wild versus cultivated seeds. We also demonstrated the importance of a genetic component in bruchid performance: longevity, fecundity, larval development, adult For example, on the same host type, some females laid twice as many eggs as females from Thus, the performance and behavior of Z. subfasciatus are not only affected by environmental factors such as the quality of the seeds on which they develop, but also have a genetic basis which can counterbalance a less suitable quality of the host plant. For a crop pest such as Z.subfasciatus, its ability to survive and adapt on host plants of differing quality may be an important attribute to consider for pest management.

    Residual toxicity and leaf protection capability of five pyrethroids, professional and home garden azadirachtin formulations, and six other bioinsecticides for the home landscape were evaluated against the Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), on linden, Tilia cordata L. Capacity of intoxicated beetles to recover and subsequently feed and disperse also was evaluated to provide insight on activity characteristics of the different compounds. Intact shoots were sprayed and left in the field for varying intervals before being challenged with beetles in no-choice and choice tests. All pyrethroids except permethrin gave greater leaf protection, knockdown, and kill than did carbaryl, the standard, after 14 d of weathering. Deltamethrin, cyfluthrin, bifenthrin, and lamda-cyhalothrin gave a high level of protection for at least 19 d, and azadirachtin (Azatin XL) deterred feeding in choice tests for as long as 14 d. Home garden formulations containing pyrethrins in canola oil (Pyola) or azadiractin (Neem-Away) gave good short-term (< 3-d) protection. Formulations of capsaicin, rotenone + pyrethrins, kaolin particle film, D-limonene, or garlic extract were ineffective, the latter two formulations being highly phytotoxic to linden. Results of this study should help support updating of guidelines for insecticidal control of Japanese beetles. PMID:17461070

    The introduced plant Miconia calvescens (Melastomataceae) poses a grave threat to Hawaii's native ecosystems and biodiversity. One potential candidate for classical biological control is Cryptorhynchus melastomae (Coleoptera: Curculionidae: Cryptorhynchinae), a stem-boring weevil from Central and South America. This weevil feeds on M. calvescens in its native Costa Rica and has been successfully reared under greenhouse conditions. Comparison of its environmental conditions in Costa Rica with those in the Miconia infested areas of Hawaii indicates the latter is a suitable habitat for C. melastomae. C. melastomae has one or two generations per year. Adults feed on new stems, petioles, leaf buds, veins, and lamina, whereas larvae mine the stem until pupation. Adults appear to prefer saplings for oviposition and feeding. Under greenhouse conditions both adults and larvae can seriously damage and kill small M. calvescens. Preliminary host testing indicates that C. melastomae may be family specific on Melastomataceae. However, because Hawaii lacks native melastomes and has many other serious melastome weeds, a family specific insect may be suitable as a biocontrol agent in this case. PMID:22182550

    Larvae of scarab beetles (Coleoptera: Scarabaeidae) are important contaminant and root-herbivore pests of ornamental crops. To develop alternatives to conventional insecticides, 24 plant-based essential oils were tested for their acute toxicity against third instars of the Japanese beetle Popillia japonica Newman, European chafer Rhizotrogus majalis (Razoumowsky), oriental beetle Anomala orientalis (Waterhouse), and northern masked chafer Cyclocephala borealis Arrow. Diluted solutions were topically applied to the thorax, which allowed for calculating LD50 and LD90 values associated with 1 d after treatment. A wide range in acute toxicity was observed across all four scarab species. Of the 24 oils tested, allyl isothiocyanate, cinnamon leaf, clove, garlic, and red thyme oils exhibited toxicity to all four species. Allyl isothiocyanate was the most toxic oil tested against the European chafer, and among the most toxic against the Japanese beetle, oriental beetle, and northern masked chafer. Red thyme was also comparatively toxic to the Japanese beetle, oriental beetle, European chafer, and northern masked chafer. Interspecific variability in susceptibility to the essential oils was documented, with 12, 11, 8, and 6 of the 24 essential oils being toxic to the oriental beetle, Japanese beetle, European chafer, and northern masked chafer, respectively. Analysis of the active oils by gas chromatography-mass spectrometry revealed a diverse array of compounds, mostly consisting of mono- and sesquiterpenes. These results will aid in identifying active oils and their constituents for optimizing the development of plant essential oil mixtures for use against scarab larvae. PMID:23448028

    The chrysomelid beetle Colaspis crinicornis Schaeffer (Coleoptera: Chrysomelidae) occurs primarily in the Great Plains region of the United States. Little is known about the biology and ecology of this species, but over the last decade, it has become increasingly common in the corn, Zea mays L., and soybean, Glycine max (L.) Merrill, agroecosystem of southeastern Nebraska. As part of a larger comprehensive project to understand the natural history and pest potential of this species, laboratory experiments were conducted to study the developmental biology, morphological characters of immature stages, and the effect of adult diet on consumption, longevity, and fecundity. Females readily deposited egg clusters in the soil, and percentage egg hatch was high under laboratory conditions. Larvae and pupae were confirmed to be soil-dwelling stages. C. crinicornis has relatively short egg, pupal, and adult stages with the majority of its life cycle spent in the larval stage. Results of choice and no-choice adult feeding experiments indicate that diets of corn or soybean leaves did not significantly affect consumption, longevity, or fecundity of adult C. crinicornis, suggesting that corn and soybean leaves are similarly suitable food sources for adults. The ability to effectively utilize tissues from very different plant families as adult food sources suggests that C. crinicornis is polyphagous in the field. PMID:26106090

    The weevil Aegorhinus superciliosus Guérin (Coleoptera: Curculionidae), which is endemic to Central-Southern Chile and Argentina, is one of the major berry pests in Chile and the most important pest in the La Araucanía Region (38°44'9″S, 72°35'25″W). Due to the poor effectiveness and problems surrounding the implementation of the traditional control methods using organophosphate and carbamate insecticides, new strategies for controlling this pest are needed. In this communication, we evaluated the behavioral responses of male and female A. superciliosus to volatile compounds released from the essential oil (EO) obtained from the heartwood of Pilgerodendron uviferum (D. Don) Florin using olfactometric bioassays. The composition of the EO was analyzed using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). According to these analyses, δ-cadinol (24.16%), cubenol (22.64%), 15-copaenol (15.46%) and δ-cadinene (10.81%) were the principal components of the EO. The Pilgerodendron uviferum EO, which is almost exclusively composed of sesquiterpenes (99.5%), exhibited a repellent effect against A. superciliosus adults, regardless of the sex or concentration used (56.6 mg/cm³ and 1.58 × 10(-2) mg/cm³). The EO has low volatility and greater persistence than the EOs composed of monoterpenes and is considered a good model in the search for raspberry weevil repellents. PMID:27110756

It is known that 85% flower plants are pollinated by the insects. The adults of Tachinidae (Insecta, Diptera) such as Phasiinae and Tachinini are important insects of flower visitors and pollinators and are seen commonly on different kinds of flowers and may function as pollinators for a wide diversity of plant taxa, but their importance in this respect has been largely unexplored. In this study, a checklist of the common Tachinidae of China as flower visitors and pollinators is reviewed by the observation of tachinid specimens, references, photos and collecting experiences, including 119 tachinid species of 54 genera, 18 tribes of 4 subfamilies. These tachinid flies play a significant role as natural enemies in the production of agriculture, forestry and animal husbandry on grasslands, plant protection, biological control of pests and the stability of terrestrial ecological communities.

    Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), plum curculio, is a serious direct pest of North American tree fruit including, apples, cherries, peaches and plums. Historically, organophosphate insecticides were used for control, but this tool is no longer registered for use in tree fruit. In addition, few organically approved insecticides are available for organic pest control and none have proven efficacy as this time. Therefore, promoting biological control in these systems is the next step, however, little is known about the biological control pathways in this system and how these are influenced by current mechanical and cultural practices required in organic systems. We used molecular gut-content analysis for testing field caught predators for feeding on plum curculio. During the study we monitored populations of plum curculio and the predator community in a production organic apple orchard. Predator populations varied over the season and contained a diverse assemblage of spiders and beetles. A total of 8% of all predators (eight Araneae, two Hemiptera, and six Coleoptera species) assayed for plum curculio predation were observed positive for the presence of plum curculio DNA in their guts, indicating that these species fed on plum curculio prior to collection Results indicate a number of biological control agents exist for this pest and this requires further study in relation to cultural practices.

    Various types of weapon traits found in insect order Coleoptera are known as outstanding examples of sexually selected exaggerated characters. It is known that the sex determination gene doublesex (dsx) plays a significant role in sex-specific expression of weapon traits in various beetles belonging to the superfamily Scarabaeoidea. Although sex-specific weapon traits have evolved independently in various Coleopteran groups, developmental mechanisms of sex-specific expression have not been studied outside of the Scarabaeoidea. In order to test the hypothesis that dsx-dependent sex-specific expression of weapon traits is a general mechanism among the Coleoptera, we have characterized the dsx in the sexually dimorphic broad-horned beetle Gnatocerus cornutus (Tenebrionidea, Tenebirionidae). By using molecular cloning, we identified five splicing variants of Gnatocerus cornutus dsx (Gcdsx), which are predicted to code four different isoforms. We found one male-specific variant (GcDsx-M), two female-specific variants (GcDsx-FL and GcDsx-FS) and two non-sex-specific variants (correspond to a single isoform, GcDsx-C). Knockdown of all Dsx isoforms resulted in intersex phenotype both in male and female. Also, knockdown of all female-specific isoforms transformed females to intersex phenotype, while did not affect male phenotype. Our results clearly illustrate the important function of Gcdsx in determining sex-specific trait expression in both sexes. PMID:27404087

    Full Text Available O esclarecimento de aspectos do comportamento de gorgulhos (Sitophilus spp. em sementes de trigo armazenadas e o acompanhamento da qualidade física e fisiológica das sementes neste contexto, é essencial para aprimorar o monitoramento das sementes durante a armazenagem. Com o objetivo de avaliar a eficiência do inseticida fenitrotion, quanto à proteção oferecida às sementes de trigo contra os insetos Sitophilus oryzae (L. (Coleoptera: Curculionidae e de acompanhar a germinação das sementes tratadas ou não com inseticida, durante o armazenamento, sementes de trigo dos cultivares IAC-120 e IAC-350 foram tratadas ou não com fenitrotion três meses após a colheita e armazenadas em condições de ambiente de laboratório, em Campinas (SP, durante 15 meses. Em intervalos trimestrais, adultos de S. oryzae foram colocados nas amostras de sementes de cada uma das repetições dos tratamentos com insetos. Avaliou-se a sobrevivência desses insetos, bem como a progênie resultante. Em seguida, as sementes das amostras das repetições de todos os tratamentos com e sem insetos foram analisadas quanto ao grau de umidade, germinação e infestação por insetos. O inseticida fenitrotion, na dose recomendada pelo fabricante, não permitiu a proteção das sementes contra a infestação por S. oryzae, mesmo por períodos curtos de dois meses e que, na ausência de insetos, as sementes de trigo com elevado potencial de germinação inicial podem mantê-lo inalterado por períodos de 14 a 17 meses após a colheita, quando armazenadas em condições ambientes, em regiões com clima semelhante ao de Campinas.Clarifying aspects of the weevils (Sitophilus spp. behavior on stored wheat seeds, considering the seed quality, is essential to improve the seed management during storage. In order to evaluate the efficiency of the insecticide fenitrothion as protecting wheat seeds against Sitophilus oryzae (L. (Coleoptera: Curculionidae and to measure the seed

    Peppers (Capsicum spp.) are an important crop in the USA, with about 32,000 ha cultivated in 2007, which resulted in $588 million in farm revenue. The pepper weevil, Anthonomus eugenii Cano (Coleoptera: Curculionidae), is the most troublesome insect pest of peppers in the southern United States. It is therefore urgent to find different vulnerabilities of pepper cultivars, fruit and plants parts, fruit colors and sizes, and timing to infestation by A. eugenii. Also relevant is testing whether fruit length and infestation state affect fruit numbers, weights, and proportions of fruit that are infested. Counts of A. eugenii adults and marks from oviposition and feeding suggested that C. chinense Jacquin "Habanero" was least susceptible, and C. annuum L. cultivars "SY" and "SR" were most susceptible. Comparison of plant parts and fruit sizes revealed that A. eugenii preferred the peduncle, calyx, and top of pepper fruits over the middle, bottom, leaves, or remainder of flowers. Anthonomus eugenii does not discriminate between green or yellow fruit color nor vary diurnally in numbers. Based on adult counts, medium to extra-large fruits (≥1.5 cm long) attracted more weevils than small fruits (<1.5 cm). However based on proportions of fruit numbers or fruit weights that were infested, there were no differences between large and small fruits. Choice of pepper cultivar can thus be an important part of an IPM cultural control program designed to combat A. eugenii by reduced susceptibility or by synchronous fruit drop of infested fruits. Our results are potentially helpful in developing scouting programs including paying particular attention to the preferred locations of adults and their sites of feeding and oviposition on the fruit. The results also suggested the potential value of spraying when the fruits are still immature to prevent and control infestation. PMID:26959066

    Full Text Available We review the diving-beetle genus Rhantus Dejean of Madagascar (Coleoptera, Dytiscidae, Colymbetinae based on museum collection holdings and recently collected expedition material. Both morphology and DNA is used to test species boundaries, in particular whether newly collected material from the Tsaratanana mountains in the north represent a new species or are conspecific with Rhantus manjakatompo Pederzani and Rocchi 2009, described based on a single male specimen from the central Ankaratra mountains. DNA of the holotype of R. manjakatompo was successfully extracted in a non-destructive way and sequenced. The general mixed Yule coalescent model applied to an ultrametric tree constructed from mitochondrial cytochrome c oxidase subunit I (COI sequence data delimited three species. Morphological characters supported the same species unambiguously. We therefore recognise three species of Rhantus to occur in Madagascar: R. latus (Fairmaire, 1869, R. bouvieri Régimbart, 1900 and R. manjakatompo Pederzani and Rocchi, 2009. All three species are endemic to Madagascar and restricted to the highlands of the island. Rhantus stenonychus Régimbart, 1895, syn. n., is considered a junior synonym of R. latus. We designate lectotypes for R. bouvieri and R. goudoti Sharp, 1882, the latter a junior synonym of R. latus. We provide descriptions, a determination key, SEM-images of fine pronotal and elytral structures, distribution maps, habitus photos, and illustrations of male genitalia and pro- and mesotarsal claws. We discuss the role of the Manjakatompo forest as a refugium for Madagascan Rhantus diversity and other endemics of the montane central high plateau.

    The aim of this study was to evaluate the effectiveness of the entomopathogenic fungi (EPF), Beauveria bassiana (Bals.) Vuill. (Deuteromycotina: Hyphomycetes) strain PPRI 5339 [BroadBand, an emulsifiable spore concentrate (EC) formulation] and Metarhizium anisopliae (Metsch.) Sorokin (Hypocreales: Clavicipitaceae) strain F52 [Met52, both EC and granular (GR) formulations] against the larvae of Polyphylla fullo (L.) (Coleoptera: Scarabaeidae). Larvicidal bioassays were performed in foam boxes (100 by 75 by 50 cm; length by width by height), containing moist soil medium with some humus and potato tubers as food. Although the B. bassiana product (min. 4 × 10(9) conidia/ml) was applied at 100, 150, and 200 ml/100 l water; M. anisopliae strain F52 was applied at 500, 1,000, and 1,500 g/m(3) of moist soil medium for GR (9 × 10(8) cfu/g) and 75, 100, and 125 ml/100 l water for EC (5.5 × 10(9) conidia/ml) formulation. Both fungi were pathogenic to larvae of the pest; however, young larvae (1st and 2nd instars) were more susceptible to infection than older ones (3rd instar). Mortality rates of young and older larvae varied with conidial concentration of both fungi and elapsed time after application. The B. bassiana product was more effective than both of the formulations of the M. anisopliae product, causing mortalities up to 79.8 and 71.6% in young and older larvae, respectively. The highest mortality rates of young and older larvae caused by the M. anisopliae product were 74.1 and 67.6% for the GR formulation, 70.2 and 61.8% for the EC formulation, respectively. These results may suggest that both fungi have potential to be used for management of P. fullo. PMID:25881632

    There are relatively few experimental studies and risk assessments of the effects on non-target insects from ultra-low volume (ULV) insecticides used for management of adult mosquitoes. Therefore, we evaluated factors that may influence the ability of an insect to intercept the insecticide at the time of application by using Hippodamia convergens (Coleoptera: Coccinellidae) in field bioassay experiments in 2011 and 2015. Treatment factors included different distances, two cage heights (ground-level and 1.5 m above ground) to the point of the application, and covered vs. uncovered cage faces (2015 only). Insecticides used included a water-based formulation (Aqua-Reslin®) and an oil-based formulation (Permanone® 30-30) of permethrin. Cage height was highly significant both years, with much less acute (i.e., short-term exposure) mortality at ground-level compared with 1.5 m. In 2011, acute mortality was less at ground-level (mean = 3.2%, median = 0%) compared to 1.5 m (mean = 85.2%, median = 100%). Cage type also was highly significant, with less mortality in covered cages compared to uncovered cages. Mortality by cage height and cage type was as follows: ground level, covered cage (mean = 2.8%, median = 0.1%); ground level, uncovered cage (mean = 41.9%, median = 9.6%); 1.5 m, covered cage (mean = 6.8%, median = 0%); 1.5 m, uncovered cage (mean = 83.7%, median = 100%). Results suggest that acute mortality to non-target insects may vary considerably based on their height and their ability to directly intercept the insecticide as the aerosol passes through the area being sprayed.

    Water beetles are one of the dominant macroinvertebrate groups in inland waters and are excellent ecological indicators, reflecting both the diversity and composition of the wider aquatic community. The predaceous water beetles (Hydradephaga) make up around one-third of known aquatic Coleoptera and, as predators, are a key group in the functioning of many aquatic habitats. Despite being relatively well-known taxonomically, ecological studies of these insects in tropical and subtropical systems remain rare. A dedicated survey of the hydradephagan beetles of the Lake St Lucia wetlands (South Africa) was undertaken between 2013 and 2015, providing the first biodiversity census for this important aquatic group in the iSimangaliso Wetland Park, a UNESCO World Heritage Site within the Maputaland biodiversity hotspot. A total of 32 sites covering the entire spectrum of waterbody types were sampled over the course of three collecting trips. The Lake St Lucia wetlands support at least 68 species of Hydradephaga, a very high level of diversity comparing favourably with other hotspots on the African continent and elsewhere in the world and a number of taxa are reported for South Africa for the first time. This beetle assemblage is dominated by relatively widespread Afrotropical taxa, with few locally endemic species, supporting earlier observations that hotspots of species richness and centres of endemism are not always coincident. Although there was no significant difference in the number of species supported by the various waterbody types sampled, sites with the highest species richness were mostly temporary depression wetlands. This contrasts markedly with the distribution of other taxa in the same system, such as molluscs and dragonflies, which are most diverse in permanent waters. Our study is the first to highlight the importance of temporary depression wetlands and emphasises the need to maintain a variety of wetland habitats for aquatic conservation in this biodiverse

    Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) has killed millions of Fraxinus spp. trees in North America. While all Fraxinus species assessed to date can be colonized, A. planipennis attraction to host trees varies among species and with tree health. We established a plantation of 105 trees (21 trees each of four North American species Fraxinus americana L., Fraxinus nigra Marshall, Fraxinus pennsylvanica Marshall, Fraxinus quadrangulata Michaux, and the Asian species, Fraxinus mandshurica Ruprecht), and determined whether resistance to A. planipennis could be enhanced by fertilizer or paclobutrazol applications. Differences among species overshadowed most treatment effects. In 2010, A. planipennis survival over 14 d was 53% when beetles were caged with F. nigra, 30-32% when beetles were caged with F. americana, F. pennsylvanica, or F. mandshurica, and only 14% for beetles caged with F. quadrangulata. In 2011, beetle survival was lower for beetles caged with F. quadrangulata (33%) than F. americana (72%) or F. mandshurica (80%). In 2010 and 2011, leaf weight consumed by beetles was the same among Fraxinus species. However, beetles caged on F. quadrangulata consumed less leaf area than that by beetles caged with other ash species. In 2011, when trees were exposed to wild A. planipennis, larval density (per m(2)) was highest on F. nigra (235.9 ± 36.41) and F. pennsylvanica (220.1 ± 39.77), intermediate on F. americana (40.7 ± 11.61), and lowest on F. quadrangulata and F. mandshurica (2.0 ± 0.98 and 1.5 ± 0.67, respectively). Results indicate F. quadrangulata and F. mandshurica were relatively resistant to A. planipennis, F. nigra and F. pennsylvanica were highly vulnerable, and F. americana was intermediate. PMID:26313182
