Abstract Introduction. Beekeeping in Honduras is an important activity for the livestock sector, threatened by the presence of pests and diseases that affect its development and production. Objective. To determine the parasitic load of Varroa destructor and Vairimorpha (Nosema) spp. associated with hygienic behavior, productivity, and the presence of other pests in Apis mellifera hives in the municipality of Tomalá, Lempira department, Honduras. Materials and Methods. A study was carried out on 57 samples from hives in 19 apiaries to determine the infestation rate of V. destructor. The average infection rate of Vairimorpha spp. was determined using the Cantwell method. Additionally, the association between parasitic loads and productivity, hygienic behavior, and the presence of other pests was determined through a stratified analysis based on whether or not treatment against Varroa spp. was used. Associations were determined using the non-parametric Mann-Whitney U and Kruskal-Wallis tests. Results. The infestation rates for V. destructor in dispersal and larval stages were 3.48 % and 6.82 %, respectively. The use of chemical treatment showed no association with the infestation rate of V. destructor in either larvae or a dults (p≥0.05). The presence of the small hive beetle (SHB) was associated with a higher infestation of V. destructor in larvae (p<0.007) in untreated hives. The infection range of Vairimorpha spp. was classified as very light with 5×104 spores per sample. The Vairimorpha spp. load showed no association with the mentioned variables (p≥0.05). Conclusion. The results indicate that varroosis is a disease of importance in the municipality of Tomalá, Lempira department, Honduras, associated with hygienic behavior and the presence of SHB in the hives. Nosemosis showed a very light infection.

ABSTRACT The cowpea is a legume with a high nutritional value and represents one of the most important self-consumption items in the country. However, under storage conditions its main problem are bruchids, which decrease the nutritional value and fertility of the seeds. Bruchids spread more frequently unintentionally throughout the world, this is due their adaptability. In the first months of 2023, damage was observed to stored cowpea grains of the species Vigna unguiculata, presenting round holes, decreasing the nutritional value and fertility of the seeds. The inspection of grains recorded the presence of a beetle, which was identified as Decellebruchus atrolineatus, Family Chrysomelidae, Subfamily Bruchinae.

RESUMEN El poroto es una leguminosa comestible con un alto valor nutritivo y representa uno de los rubros de autoconsumo más importantes en el país. Sin embargo, en condiciones de almacenamiento su principal problema son los brúquinos, quienes disminuyen el valor nutricional y la fertilidad de las semillas. Por la adaptación que poseen, los brúquinos, se diseminan con mayor frecuencia de manera involuntaria. En los primeros meses del año 2023, fueron observados daños en granos almacenados de poroto de la especie Vigna unguiculata, presentando orificios redondeados. La inspección de dichos granos registró la presencia de un coleóptero, que fue identificado como Decellebruchus atrolineatus, Familia Chrysomelidae, Subfamilia Bruchinae.

Abstract The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), generally reaches pest status in stored grain. Chemical control is the most used method for population suppression, which can cause adverse impacts, thus creating a need for alternatives such as using inert powders. The present work aims to verify the effect of different concentrations of different types of inert powders on the mortality of S. zeamais in the laboratory. To this end, the experiments were carried out in a completely randomized design, with 13 treatments and four replications, ten adults per replication, where the effect of different inert powders (basalt powder, gypsum powder, and diatomaceous earth) was tested at concentrations of 0.025 g, 0.05 g, 0.1 g and 0.2 g/20 g of corn grains. Variance, normality, and homoscedasticity tests were applied in addition to controlling efficiency (CE%), median lethal time (TL50), and survival curves. All treatments caused mortality in S. zeamais, and all concentrations with diatomaceous earth were more efficient, with 100% mortality at 20 days, followed by the treatment of 0.2 g of gypsum powder/20 g of corn grains, with superior efficiency, to 95% in 20 days and 100% in 30 days. The results indicated that treatments with diatomaceous earth had the highest mortality rate and the best average survival time. weevil Motschulsky 185 Coleoptera (Coleoptera Curculionidae, Curculionidae , Curculionidae) grain suppression impacts S laboratory end design 1 replications replication basalt powder 0025 0 025 0.02 005 05 0.0 01 0. 02 2 g20 g/2 grains Variance normality CE%, CE CE% (CE%) TL50, TL50 TL (TL50) curves efficient 100 powder20 powder/2 95 3 18 002 00 g2 g/ (CE% TL5 (TL50 10 powder2 powder/ 9 (CE (TL5 (TL

Resumo O gorgulho-do-milho, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), geralmente atinge o status de praga em grãos armazenados. O controle químico é o método mais utilizado para sua supressão populacional, podendo causar impactos adversos, surge assim a necessidade de alternativas como o uso de pós inertes. O presente trabalho tem como objetivo verificar o efeito de diferentes concentrações de diferentes tipos de pós inertes na mortalidade de S. zeamais no laboratório. Para tanto, os experimentos foram realizados em delineamento inteiramente casualizado, com 13 tratamentos e quatro repetições, 10 adultos por repetição. Onde testou-se o efeito de diferentes pós inertes (pó de basalto, pó de gesso e terra diatomácea), nas concentrações de 0,025 g, 0,05 g, 0,1 g e 0,2 g/20 g de grãos de milho. Sendo aplicados testes de variância, normalidade e homocedasticidade, além de eficiência de controle (CE%), tempo letal mediano (TL50) e curvas de sobrevivência. Todos os tratamentos causaram mortalidade em S. zeamais, e todas as concentrações com terra diatomácea foram mais eficientes com 100% de mortalidade aos 20 dias, seguido do tratamento de 0,2 g de pó de gesso/20 g de grãos de milho, com eficiência superior a 95% aos 20 dias e 100% em 30 dias. Os resultados indicaram que os tratamentos com terra diatomácea apresentaram a maior taxa de mortalidade e a melhor média em termos de tempo de sobrevivência. gorgulhodomilho, gorgulhodomilho gorgulho milho gorgulho-do-milho Motschulsky 185 Coleoptera (Coleoptera Curculionidae, Curculionidae , Curculionidae) armazenados populacional adversos S laboratório tanto casualizado 1 repetições repetição testouse testou se basalto diatomácea, diatomácea) 0025 0 025 0,02 005 05 0,0 01 0, 02 2 g20 g/2 variância homocedasticidade CE%, CE CE% (CE%) TL50 TL (TL50 sobrevivência 100 gesso20 gesso/2 95 3 18 002 00 g2 g/ (CE% TL5 (TL5 gesso2 gesso/ 9 (CE (TL

Resumo Os besouros terrestres (besouros carabídeos) podem ser encontrados em praticamente todos os hábitats do mundo. Eles são uma das três famílias mais diversas de besouros existentes, com 34.275 espécies documentadas, e servem como marcadores ecológicos vitais em todos os ambientes. Os besouros vivos edáficos capturam e comem uma grande variedade de artrópodes que vivem no solo. No caso de ervas daninhas, os besouros terrestres, em sua maioria, comem sementes delas e ajudam a regular suas populações. Os resultados do estudo de campo em agrocenoses no sudeste do Cazaquistão de 2019 a 2020 são apresentados neste artigo. Foram descobertas 27 espécies de besouros terrestres de 9 gêneros como consequência do estudo. As 670 armadilhas de solo renderam um total de 1.012 besouros. Besouros mesófilos politópicos fornecem a base para a fauna de agrocenoses. Higrófilos, mesófilos e euribiontes estão entre os besouros encontrados em áreas irrigadas, assim como espécies mistas e herbívoras. Em campos e estepes, a família Carabidae de besouros é a mais numerosa. Como resultado, dependendo do hábitat e da temperatura do ar, podem ser encontrados besouros de dieta mista. As espécies de besouros em todos os campos da área de investigação estão de acordo com o complexo dos insetos. Durante a estação de crescimento, a dieta dos besouros muda: os besouros predadores têm precedência, seguidos dos besouros de dieta mista.

Abstract Ground beetles (Carabid beetles) may be found in virtually all of the world's habitats. They are one of the three most diverse families of extant beetles, with 34,275 species documented, and they serve as vital ecological markers in all environments. Edaphic living beetles catch and eat a wide variety of arthropods that live in the soil. In the case of weeds, most of the ground beetles eat their seeds and help regulate their populations. The findings of a field study in agrocenoses in South-East Kazakhstan from 2019 to 2020 are presented in this article. Twenty-seven ground beetle species from 9 genera were discovered as a consequence of the study. 670 soil traps yielded a total of 1012 beetles. Polytopic mesophilic beetles provide the foundation of the agrocenoses fauna. Hygrophils, mesophiles, and eurybionts are among the beetles found in irrigated areas, as are mixed and herbivorous species. The Carabidae family of beetles is the most numerous in fields and steppe settings. As a result, mixed-diet beetles can be found depending on the habitat and air temperature. The species of beetles in all fields in the investigation area are in accordance with the insects’ complex. During the growth season, the diet of beetles shifts: predatory beetles take precedence initially, followed by mixed-diet beetles.

ABSTRACT Great advances were made in recent years regarding the description of immatures of Cassidinae and their taxonomy as a whole, but many taxa remain undescribed. This study focuses on updating morphological data for Hybosa acutangula Spaeth, 1913 (Chrysomelidae: Cassidinae: Ischyrosonychini), a tortoise beetle native of South America, which was collected in Fridericia florida (DC.) L. G. Lohmann in the Brazilian Cerrado. We provide descriptions and illustrations of the morphology of the larva, pupa, and genitalia of adults, all of which are novel for this genus. The main discerning features for this species among other Ischyrosonychini are the lack of dark patterns in the dorsum of either the larvae, being limited to the dark scoli and the cranium, or the pupae, and a much reduced anal fork. We also present the first record of parasitism by Chalcididae wasps, Brachymeria sp. Westwood, 1832 and Conura sp. Spinola, 1837. Morphological comparisons remain limited demanding further studies with other species of Ischyrosonychini, as to better understand the placement of this species within the taxonomy of tortoise beetles. whole undescribed Spaeth 191 Chrysomelidae (Chrysomelidae , Ischyrosonychini) America DC.

Antibiotics can contaminate the environment as a result of improper disposal. The induction of doxycycline in the environment could give rise to lineages of the cucurbit beetle Diabrotica speciosa containing resistant endosymbiotic microorganisms, giving rise to bacterial strains capable of biodegrading these antibiotic residues. This work determined the relationship between the intestinal microbiota of D. speciosa and its ability to biodegrade an antibiotic. Bacterial strains of Enterobacter cloacae and Stenotrophomonas maltophila isolated from the gastrointestinal tract of D. speciosa were evaluated for the biodegradation of doxycycline. An analytical method for the extraction and quantification of doxycycline by high-efficiency liquid chromatography-ultraviolet detection (HPLC-UV) was developed and applied to monitor the biodegradation rates during bacterial growth for nutrient and nutrient-deficient media, both supplemented with the antibiotic. Degradation kinetics showed a decrease in antibiotic concentration after 96 h in saline medium, with recoveries of 63.1 and 87.7% for E. cloacae and S. maltophilia, respectively. Two degradation products were then identified and characterized from the liquid chromatography-high resolution mass spectrometry data after bioassays with E. cloacae. The gastrointestinal tract of insects such as D. speciosa can be a source of useful microbes for biotechnological processes such as the biodegradation of exogenous organic compounds in the environment. disposal microorganisms residues D highefficiency high efficiency chromatographyultraviolet chromatography ultraviolet HPLCUV HPLC UV (HPLC-UV nutrientdeficient deficient media 9 medium 631 63 1 63. 877 87 7 87.7 E S maltophilia respectively chromatographyhigh 6 8 87.

Abstract Pasturelands are characterized as grasslands utilized for cattle raising and consist of natural or exotic vegetation, predominantly grasses. In the context of sustainable production, the biodiversity of insects within grazing environments holds significant value. Dung beetles play a crucial role in sustaining pasturelands as the burial of feces by these beetles fosters ecological services indispensable for maintaining a robust and healthy environment. Given that different dung beetle species contribute to distinct environmental benefits, a comprehensive understanding of the species present in pasturelands, their origins, and the ecological services they provide is imperative. This study endeavors to compile comprehensive information on dung beetle species native to South America, emphasizing taxonomic precision and a confirmed affinity for cattle dung. Our findings are derived from a synthesis of literature and observational data, incorporating location information obtained from taxonomic revisions and specimen labels of specimens housed at CEMT. In South America, a total of 57 dung beetle species are documented that inhabit grazing areas and actively feed on cattle manure. These areas span diverse biomes encompassing native and/or introduced grasslands, which may include deforested sections within forest biomes such as Chaco, Pantanal, Cerrado, Caatinga, Pampa, Atlantic Forest, Amazon Forest, Paramo, Puna, Llanos, and Patagonia. The preponderance of species identified fall within the paracoprid category, recognized as particularly vital for the sustainability of pasturelands. Despite their acknowledged importance, a noticeable knowledge gap impedes the effective conservation of these species. This gap is a focal point of discussion in this study, addressing the challenges and opportunities for enhancing conservation efforts. The species documented in this research exhibit notable economic and environmental relevance in the context of sustainable livestock production, emphasizing the urgency and significance of initiatives that prioritize their conservation. vegetation grasses production value environment benefits origins imperative America data CEMT 5 manure andor Chaco Pantanal Cerrado Caatinga Pampa Forest Paramo Puna Llanos Patagonia category importance efforts

Resumo Pastagens são áreas formadas por vegetação nativa ou exótica, principalmente gramíneas, e são utilizadas na pecuária. A diversidade de insetos em áreas de pastagens é muito valiosa, especialmente quando consideramos os métodos de produção sustentável. Besouros rola-bostas são importantes para a sustentabilidade em pastagens porque o enterrio de esterco promove benefícios essenciais para a manutenção do ambiente pastoril. Espécies diferentes exercem diferentes serviços ecossistêmicos, logo é necessário saber quais espécies estão presentes em áreas de pastoreio para saber quais são os benefícios que elas podem proporcionar. Aqui reunimos todas as informações disponíveis para as espécies taxonomicamente bem definidas de rola-bostas nativos da América do Sul e que são conhecidas por utilizar fezes bovinas como recurso para alimentação e nidificação. Usamos dados encontrados na literatura, em observações de campo e em etiquetas de espécimes depositados na CEMT. São registradas 57 espécies de rola-bostas nativos da América do Sul que se alimentam e nidificam em fezes bovinas, e estas estão distribuídas nos seguintes biomas: Chaco, Pantanal, Cerrado, Caatinga, Pampa, áreas abertas da Mata Atlântica e da Floresta Amazônia, Paramo, Puna, Llanos e Patagônia. A maioria das espécies são de paracoprídeos e estes são considerados os mais importantes para as áreas de pastagem. No entanto, existe uma grande lacuna de conhecimento em história natural, o que dificulta a efetividade da conservação dessas espécies. Todas as espécies listadas neste trabalho têm potencial relevância econômica e ambiental na pecuária sustentável e, portanto, o estudo e conservação delas devem ser priorizadas. exótica gramíneas valiosa rolabostas rola bostas pastoril ecossistêmicos proporcionar nidificação literatura CEMT 5 biomas Chaco Pantanal Cerrado Caatinga Pampa Amazônia Paramo Puna Patagônia pastagem entanto natural portanto priorizadas

ABSTRACT Bird droppings are an unusual food resource for coprophagous insects and used mostly by opportunistic decomposers. Among them, dung beetles feed mainly on dung, although the species differ in their trophic plasticity. Here we report a record of a dung beetle, Canthidium cf. gracilipes, reaching and manipulating the dropping of a passeriform bird, Dendrocincla fuliginosa (Dendrocolaptidae). The behavior was observed in an urban forest fragment located in the Amazonian city of Manaus, Brazil. Two hours after the bird defecated, the dung beetle reached the dropping and started manipulating them with its fore- and hindlegs. It did not eat the dung, though. For a clear understanding of the relationships between bird droppings and Amazonian dung beetles, it will be important to perform standardized experiments with a wide variety of native dung and carrion types. decomposers plasticity cf gracilipes Dendrocolaptidae. Dendrocolaptidae . (Dendrocolaptidae) Manaus Brazil defecated fore hindlegs though types (Dendrocolaptidae

RESUMO Excrementos de aves correspondem a um recurso alimentar pouco comum para insetos coprófagos, sendo utilizados geralmente por decompositores oportunistas. Entre eles, os rola bostas se alimentam principalmente de fezes, entretanto a plasticidade alimentar varia entre as espécies. Neste estudo nós reportamos um registro do rola bosta Canthidium cf. gracilipes se aproximando de e manipulando os excrementos de uma ave passeriformes, Dendrocincla fuliginosa (Dendrocolaptidae). O comportamento foi observado em um fragmento localizado na cidade amazônica de Manaus, Brasil.

Resumen: En | Texto: En | PDF: En

Abstract In phytophagous insects, adaptation to a new host is a dynamic process, in which early and later steps may be underpinned by different features of the insect genome. Here, we tested the hypothesis that early steps of this process are underpinned by a shift in gene expression patterns. We set up a short-term artificial selection experiment (10 generations) for the use of an alternative host (Cicer arietinum) on populations of the bean beetle Zabrotes subfasciatus. Using Illumina sequencing on young adult females, we show the selected populations differ in the expression of genes associated to stimuli, signalling, and developmental processes. Particularly, the “C. arietinum” population shows upregulation of histone methylation genes, which may constitute a strategy for fine-tuning the insect global gene expression network. Using qPCR on body regions, we demonstrated that the “Phaseolus vulgaris” population upregulates the genes polygalacturonase and egalitarian and that the expression of an odorant receptor transcript variant changes over generations. Moreover, in this population we detected the existence of vitellogenin (Vg) variants in both males and females, possibly harbouring canonical reproductive function in females and extracellular unknown functions in males. This study provides the basis for future genomic investigations seeking to shed light on the nature of the proximate mechanisms involved in promoting differential gene expression associated to insect development and adaptation to new hosts. insects genome Here patterns shortterm short term 10 (1 generations Cicer arietinum subfasciatus stimuli signalling processes Particularly C.

ABSTRACT The earliest fossil member of Bothrideridae, Alveoderes yamamotoi Li & Cai gen. et sp. nov., is reported from mid-Cretaceous amber of northern Myanmar. Alveoderes gen. nov. appears to be most similar to extant Deretaphrus in the 3-segmented antennal club and pronotal morphology, but is also distinctive among the whole Bothrideridae in having a large cavity (possible glandular opening) at each anterior pronotal angle. Our discovery of a definitive bothriderid beetle from the late Mesozoic highlights the antiquity of the family. A key to the extant and extinct genera of Deretaphrini is added. gen sp nov midCretaceous mid Cretaceous Myanmar 3segmented segmented 3 morphology possible opening angle family added

Resumen: En | Texto: En | PDF: En

ABSTRACT The biological parameters of Necrobia rufipes (DeGeer, 1775) are estimated under controlled temperature and relative humidity. The adults, collected from industrial canine food at a supermarket in Campina Grande, state of Paraíba, Brazil, were taken to the Laboratory of Insect Systematics and Bioecology at the Universidade Estadual da Paraíba, in order to ascertain the matrix creation. The individuals were placed in boxes with hermetic sealing, each containing 20 adults, and were fed a diet of 1.8 g of fish flour, a slice of bacon, and four dog food pellets. A total of 160 eggs were individualized in the plastic recipient in a base of paper filter, covered with voil tissue, and secured with an elastic cord. The containers were placed in a B.O.D. camera at temperatures of 20, 24, 28, and 32 °C and relative humidity of 70%. The larvae received a diet composed of 0.45 g of fish flour, a slice of bacon, and dog food pellet. The development of phases was monitored daily. The life cycle from egg to adult was completed in four temperatures and encompassed four larval instars. The development speed at all stage phases was affected by temperature. Higher thermal conditions increase development speed and consequently reduce the duration of the immature and adult stages. The development of N. rufipes was completed at 20 and 32 °C, two temperatures that are not considered optimal for insect development. The fact that N. rufipes is a pest of storage grains, however, may explain why this insect is able to tolerate and develop under suboptimal temperatures.

ABSTRACT In 2000, Cleide Costa published a paper presenting the state of knowledge of the Neotropical Coleopte ra, with a focus on the Brazilian fauna. Twenty-four years later, thanks to the development of the Coleoptera section of the Taxonomic Catalog of the Brazilian Fauna (CTFB - Catálogo Taxonômico da Fauna do Brasil) through the collaboration of 100 coleopterists from all over the globe, we can build on Costa’s work and present an updated overview of the state of knowledge of the beetles from Brazil. There are currently 35,699 species in 4,958 genera and 116 families known to occur in the country, including representatives of all extant suborders and superfamilies. Our data show that the Brazilian beetle fauna is the richest on the planet, concentrating 9% of the world species diversity, with some estimates accounting to up to 15% of the global total. The most diverse family in numbers of genera is Cerambycidae (1,056 genera), while in number of species it is Chrysomelidae (6,079 species). Conotrachelus Dejean, 1835 (Curculionidae) is the most species-rich genus, with 570 species. The French entomologist Maurice Pic is the author who has contributed the most to the naming of species recorded from Brazil, with 1,794 valid names in 36 families, whereas the Brazilians Ubirajara R. Martins and Maria Helena M. Galileo are the only ones among the top-ten authors to have named species in the 21st century. Currently, approximately 144 new species of Brazilian beetles are described each year, and this average is projected to increase in the next decade to 180 species per year, or about one new Brazilian beetle every two days. 2000 ra Twentyfour Twenty four later CTFB Brasil 10 globe Costas s Brazil 35699 35 699 35,69 4958 4 958 4,95 11 country superfamilies planet 9 diversity 15 total 1,056 1056 1 056 (1,05 genera, , genera) 6,079 6079 6 079 (6,07 . species) Dejean 183 Curculionidae (Curculionidae speciesrich rich genus 57 1794 794 1,79 3 R M topten top ten st century Currently 14 year 18 days 200 3569 69 35,6 495 95 4,9 1,05 105 05 (1,0 6,07 607 07 (6,0 5 179 79 1,7 20 356 35, 49 4, 1,0 0 (1, 6,0 60 (6, 17 7 1, 2 (1 6, (6 (

Abstract Fire is an important component of ecosystems, however, for many years it was perceived as a threat and an attempt was made to exclude it, affecting the process of ecological succession, and increasing the fuel load. One of the most used strategies to restore the fire regime is prescribed burning, nonetheless the consequences on the different components of the ecosystem are still not clearly known. For this reason, in the present work the effect of a prescribed burn on the biodiversity of beetle morphospecies in a Pinus montezumae forest was evaluated, through the collection of insects in traps baited with frontalin. Statistically, significant differences were found in the morphospecies biodiversity index of the area with prescribed burning and the surrounding area to which the fire was not applied. More specimens were collected in the burned area, mainly representatives of the families Bruchidae and Curculionidae (specifically Scolytinae). In the site without prescribed burning, only 18 families of Coleoptera were present out of the 21 that were registered in the burned area, however, the Non-metric Multidimensional Scaling (NMDS) analysis showed that the composition of both communities was similar.

Resumen El fuego es un componente importante de los ecosistemas, sin embargo, durante muchos años se percibió como una amenaza y se intentó excluir, afectando el proceso de sucesión ecológica y aumentando la carga de combustibles. Una de las estrategias más utilizadas para restaurar el régimen del fuego son las quemas prescritas, pero aún no se conocen claramente las consecuencias en los distintos componentes del ecosistema. Es por esto, que en el presente trabajo se evaluó el efecto de una quema prescrita sobre la biodiversidad de morfoespecies de coleópteros en un bosque de Pinus montezumae, a través de la recolecta de insectos en trampas cebadas con frontalina. Se encontraron diferencias estadísticamente significativas en el índice de biodiversidad de morfoespecies del área con quema prescrita y el área aledaña a la que no se le aplicó el fuego. Se recolectaron más especímenes en el área con quema, sobre todo representantes de las familias Bruchidae y Curculionidae (específicamente Scolytinae). En el sitio sin quema prescrita se presentaron solo 18 familias de Coleoptera de las 21 que se registraron en el área quemada, sin embargo, el análisis de Escalamiento Multidimensional No-métrico (NMDS) mostró que la composición de ambas comunidades fue semejante.
