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.

Resumo Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causa perdas consideráveis às lavouras de soja no Brasil e em vários outros países da América do Sul. A aplicação de inseticidas biológicos pode ser uma alternativa eficaz para suprimir esta praga. O objetivo deste estudo foi avaliar a eficácia de inseticidas microbiológicos formulados a partir dos fungos Beauveria bassiana + Metarhizium anisopliae (Bometil) e B. bassiana (Ballvéria), e bactéria Bacillus thuringiensis (Acera) isoladamente e em combinação com os inseticidas químicos fipronil, etiprole e clorpirifós, contra adultos de M. armatus. Os inseticidas à base de B. bassiana + M. anisopliae foram mais patogênicos que os à base de B. bassiana, causando taxas de mortalidade acumuladas nos dez dias com 85,0 e 65,0% respectivamente. Em contraste, B. thuringiensis causou 92,5% de mortalidade. Estes produtos sozinhos e em combinação foram eficazes para o controlo nas suas concentrações mais baixas. Portanto, o uso de inseticidas microbiológicos individualmente ou em combinação com inseticidas químicos é uma alternativa promissora para o manejo integrado de M. armatus.

Abstract Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causes considerable losses to soybean crops in Brazil and several other South American countries. Applying biological insecticides can be an effective alternative to suppressing this pest. The objective of this study was to assess the efficacy of microbiological insecticides formulated from the fungi Beauveria bassiana + Metarhizium anisopliae (Bometil) and B. bassiana alone (Ballvéria), and the bacterium Bacillus thuringiensis (Acera) alone and in combination with the chemical insecticides fipronil, ethiprole and chlorpyrifos, against M. armatus adults. The insecticides based on B. bassiana + M. anisopliae were found to be more pathogenic than those based on B. bassiana, causing cumulative mortality rates in the ten days of 85.0 and 65.0% respectively. In contrast, B. thuringiensis caused 92.5% mortality. These products alone and in combination were effective for control at their lowest concentrations. Therefore, the use of microbiological insecticides individually or in combination with chemical insecticides is a promising alternative for the integrated management of M. armatus.

Abstract Zatrephina lineata (Coleoptera: Chrysomelidae) is a phytophagous insect, mainly of plants of the genera Ipomoea and Mikania. The objective was to study the development, survival and to describe the life stages of Z. lineata fed on leaves of Ipomoea pes-caprae. Biological observations were made daily with the aid of a stereoscopic microscope and the instars of this insect identified by the exuvia left between one moulting and the next. The duration of development and survival of the egg, larva and pupa stages and the first, second, third, fourth and fifth instars and of the nymph stage of Z. lineata differed, but not between sexes of this insect. The duration of development of Z. lineata was longer in the larval stage and in the fifth instar, and its survival greater in the egg and pupa stages and in the first and fifth instars. Zatrephina lineata eggs, cream-colored, are ellipsoid and deposited in groups on the adaxial surface of older I. pes-caprae leaves. The larvae of this insect go through five instars, with the first three being gregarious with chemo-behavioral defenses. The exarated pupae of Z. lineata, light yellow in color and with an oval shape flattened dorsoventrally, attach to the abaxial surface of the I. pes-caprae leaves. The shape of adults of this insect is oval, straw yellow in color with lighter longitudinal stripes and females are slightly larger than males.

Resumo Zatrephina lineata (Fabricius, 1787) (Coleoptera: Chrysomelidae) é um inseto fitófago, principalmente de plantas dos gêneros Ipomoea e Mikania. O objetivo foi estudar o desenvolvimento, a sobrevivência e descrever as fases de vida de Z. lineata alimentada com folhas de Ipomoea pes-caprae. Observações biológicas foram feitas diariamente com auxílio de microscópio estereoscópico e os ínstares desse inseto identificados pela exúvia deixada entre uma muda e outra. A duração do desenvolvimento e sobrevivência dos estágios de ovo, larva e pupa e dos primeiro, segundo, terceiro, quarto e quinto ínstares e do periodo ninfal de Z. lineata diferiu, mas não entre os sexos deste inseto. A duração do desenvolvimento de Z. lineata foi maior na fase larval e no quinto ínstar, e sua sobrevivência maior nas fases de ovo e pupa e no primeiro e quinto ínstares. Os ovos de Z. lineata, de cor creme, são elipsoides e depositados em grupos na superfície adaxial das folhas mais velhas de I. pes-caprae. As larvas desse inseto passam por cinco ínstares, sendo os três primeiros gregários com defesas quimio-comportamentais. As pupas exaradas de Z. lineata, de cor amarelo claro e formato oval achatado dorsoventralmente, fixam-se na superfície abaxial das folhas de I. pes-caprae. O formato dos adultos deste inseto é oval, de cor amarelo palha com listras longitudinais mais claras e as fêmeas são ligeiramente maiores que os machos.

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.

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 (

Resumen Se evaluó el impacto de varios plaguicidas sobre la diversidad de la artropofauna asociada al cultivo de papa comercial, en Mollepata, provincia de Anta en Cusco-Perú, para determinar que gremios tróficos (GT) de la artropofauna son afectados. Los tratamientos fueron fipronil, propineb y convencional (rotación de varios plaguicidas). Se dispusieron 35 trampas de caída en cada tratamiento con la finalidad de recolectar la artropofauna presente en el cultivo de papa. Fueron realizadas cinco aplicaciones del tratamiento correspondiente y se efectuó un total de cinco revisiones con una frecuencia de catorce días entre ellas. Las familias más abundantes fueron Hemiptera: Cicadellidae (19,82 %), Coleoptera: Chrysomelidae (16,33 %) y Diptera: Sciaridae (11,92 %). El propineb fue el tratamiento que presentó, a nivel de familia, el mayor número total de individuos. Para todo el estudio, a nivel de GT la secuencia decreciente del total de familias fue: fitófago con 30 familias (32,97 %); depredadores 23 familias (26,37 %); detritívoros 20 familias (21,98 %); parasitoides 10 familias (9,89 %); polinizadores seis familias (6,59 %) y omnívoro dos familias (2,20 %). El propineb presentó los valores del número total de individuos más altos en los fitófagos y los parasitoides. Por otro lado, los índices de diversidad alfa no presentaron diferencias entre tratamientos para los gremios omnívoros, detritívoros, polinizadores y depredadores. Los índices de diversidad beta fueron variables, obteniendo en general una mayor similaridad entre el tratamiento de fipronil y el convencional. Los GT fitófagos y parasitoides fueron los que presentaron los valores más diferenciados al evaluar el efecto de los plaguicidas en la artropofauna del suelo con base a los índices de diversidad alfa.

Abstract The impact of several pesticides on the diversity of arthropofauna associated with commercial potato cultivation was evaluated in Mollepata, province of Anta in Cusco-Peru, to determine which trophic guilds (TG) are affected. The treatments were fipronil, propineb and conventional (rotation of several pesticides). Thirty-five pitfall traps were placed in each treatment with the purpose of collecting the arthropofauna in potatoes. Five applications of the corresponding treatment were carried out and a total of five check-ups were carried out with a frequency of fourteen days. The most abundant families were Hemiptera: Cicadellidae (19.82%), Coleoptera: Chrysomelidae (16.33%) and Diptera: Sciaridae (11.92%). Propineb was the treatment that presented, at the family level, the largest total number of individuals. For the entire study, at the level of TG, the decreasing sequence of the total number of families was: phytophagous with 30 families (32.97%); predators 23 families (26.37%); detritivores 20 families (21.98%); parasitoids 10 families (9.89%); pollinators six families (6.59%) and finally omnivorous with two families (2.20%). Propineb presented the highest values of the total number of individuals in phytophages and parasitoids. On the other hand, alpha diversity indices did not present differences between treatments for omnivores, detritivores, pollinators and predators. The beta diversity indices were variable, generally obtaining greater similarity between the fipronil and conventional treatment. The phytophagous and parasitoid TGs were those that presented the most differentiated values when evaluating the effect of pesticides on soil arthropofauna based on alpha diversity indices.

ABSTRACT: Pest insects are one of the major factors affecting the productivity of sugarcane, and especially those associated with the soil, which damage the crop if not controlled. There is little information on the insect associated with the soil in the sugarcane crop in the state of Mato Grosso do Sul, Brazil. This study evaluated the occurrence, abundance and population variation of soil-associated insects in sugarcane crops in four counties in the state of Mato Grosso do Sul during a period from September 2009 to August 2010. For the capture of insects, deep in the soil trenches were (50 x 50 x 30 width x length x depth). It was observed that county of Maracaju has a high incidence of soil insects in sugarcane crop. Specimens of the family Scarabaeidae are abundant in sugarcane fields of the state of Mato Grosso do Sul, being Liogenys suturalis the predominant species. Soil insects of the Chrysomelidae family were found with greater abundance in Dourados and Naviraí while Noctuidae, represented only by the Hyponeuma taltula, occurred mainly in Dourados. Insects of the family Termitidae occur in sugarcane fields in the counties of Maracaju and Naviraí but not in Nova Alvorada do Sul and Dourados. Sphenophorus levis and Metamasius hemipterus were alsoreported in the sugarcane fields from Maracaju, being the occurrence these species the first record in the Mato Grosso do Sul State. The determined occurrence of different soil insects in the sugarcane fields may help in their management in the four counties studied.

RESUMO: Os insetos-praga são um dos principais fatores que afetam a produtividade da cana-de-açúcar e, principalmente, aqueles associados ao solo, que prejudicam a cultura se não forem controlados. Existem poucas informações sobre a fauna de insetos associada ao solo na cultura da cana-de-açúcar no estado de Mato Grosso do Sul (MS), Brasil. O objetivo deste estudo foi avaliar a ocorrência, abundância e variação populacional de insetos associados ao solo em lavouras de cana-de-açúcar em quatro municípios do estado de Mato Grosso do Sul durante o período de setembro de 2009 a agosto de 2010. Para a captura de insetos, foram feitas trincheiras (50 cm x 50 cm x 30 cm - largura x comprimento x profundidade) no solo. Observou-se que o município de Maracaju apresenta alta incidência de insetos de solo na cultura da cana-de-açúcar. Exemplares da família Scarabaeidae são abundantes nos canaviais do MS, sendo Liogenys suturalis a espécie predominante. Insetos de solo da família Chrysomelidae foram encontrados com maior abundância em Dourados e Naviraí enquanto Noctuidae, representado apenas por Hyponeuma taltula, ocorreu principalmente em Dourados. Insetos da família Termitidae ocorrem em canaviais nos municípios de Maracaju e Naviraí, mas não em Nova Alvorada do Sul e Dourados. Sphenophorus levis e Metamasius hemipterus (Coleoptera: Curculionidae) também foram encontrados nos canaviais de Maracaju, sendo a ocorrência dessas espécies o primeiro registro no MS.

Resumen: En | Texto: En | PDF: En

Abstract The objective of this study was to assess the efficiency of essential oils of cloves (Syzygium aromaticum) and thyme (Thymus vulgaris) on the control of Acanthoscelides obtectus in laboratory conditions. The extraction of the oils was executed by the hydro-distillation method in a Clevenger device, for 4 hours and the design used was completely randomized, with five replications, in a 10x8 factorial arrangement (dozes and exposition time) with ten concentrations (20; 10; 5; 2.5; 1.75; 0.75; 0.5; 0.25 and 0.0% and Tween® 5.0%). Each replication was comprised by 10 unsexed insects of A. obtectus. The variables evaluated are as follows: control efficiency and CL50 through the Proc Probit analysis. The evaluations were carried out in 1, 2, 3, 12, 24, 48, 72, and 96 hours after the treatment. The results demonstrate that the essential oils of cloves and thyme caused 100% of mortality after 48 and 72 hours, respectively, in the 20% concentration.

ABSTRACT The Mexican bean weevil Zabrotes subfasciatus (Boheman) (Coleoptera, Chrysomelidae, Bruchinae) has become one of the main pests of common bean (Phaseolus vulgaris L.) (Fabaceae) worldwide. The association of resistant bean varieties with botanical insecticides has a great potential for controlling the pest, but it has been little studied so far. Therefore, the present study aimed at selecting a botanical insecticide and evaluating its combined effect with an arcelin-bearing common bean resistant genotype against Z. subfasciatus. We evaluated three botanical insecticides, the rotenone-based Roteline® and the neem-based NeemSeto® and NeemPro®, on the development of the insect. NeemPro® was the most effective, presenting ovicidal effect and prolonging egg-to-adult period, being selected for the following bioassay. Then we evaluated the effect of NeemPro® combined with the resistant common bean genotype IAC 818 (RAZ-59) on some biological parameters of the pest. The most severe effects on Z. subfasciatus were caused by the resistant genotype. However, significant effects in some parameters of the pest were also verified for the botanical insecticide and for its combination with this resistance type/trait in the conditions of the experiment.

Abstract Management programs and efficient techniques are necessary to recover degraded ecosystems. The sewage sludge is rich in nitrogen (N) and with the potential to fertilize Sapindus saponaria L. (Sapinales: Sapindaceae), used in the recovery of degraded areas; this can affect the insect fauna. The study's objective was to evaluate, for 24 months, the abundance of chewing insects, dipterans, pollinators, and predators on S. saponaria plants fertilized with or without dehydrated sewage sludge in a degraded area. The experimental design was completely randomized (with the same characteristics) with two treatments (with or without dehydrated sewage sludge) and 24 replicates, each with one plant. The abundance of Anastrepha sp. (Tephritidae), Cerotoma sp. (Chrysomelidae), Curculionidae, Musca domestica L. (Muscidae), Mantis religiosa L. (Mantodea: Mantidae), Oxyopidae, Salticidae, Tettigoniidae (Orthoptera), and Teudis sp. (Anyphaenidae) was higher on fertilized plants. The abundances of Teudis sp. and Tmarus sp. (Thomisidae) and M. religiosa and Teudis sp. were positively correlated with chewing insects and Diptera, respectively. The population increase of insects and spiders on S. saponaria plants fertilized with dehydrated sewage sludge (bigger crowns) has shown to be suitable for recovering degraded areas with a higher number of niches and better food quality, improving the ecological indices of the area. ecosystems N (N L Sapinales (Sapinales Sapindaceae, Sapindaceae , Sapindaceae) fauna studys study s evaluate 2 months dipterans pollinators S area characteristics replicates plant sp Tephritidae, Tephritidae (Tephritidae) Chrysomelidae, Chrysomelidae (Chrysomelidae) Curculionidae Muscidae, Muscidae (Muscidae) Mantodea (Mantodea Mantidae, Mantidae Mantidae) Oxyopidae Salticidae Orthoptera, Orthoptera (Orthoptera) Anyphaenidae (Anyphaenidae Thomisidae (Thomisidae M Diptera respectively bigger crowns quality (Tephritidae (Chrysomelidae (Muscidae (Orthoptera

Resumo A degradação de ecossistemas torna necessário programas de manejo e técnicas eficientes para recuperá-los. O lodo de esgoto é rico em nitrogênio e com potencial para adubar Sapindus saponaria L. (Sapinales: Sapindaceae), utilizada na recuperação de áreas degradadas, mas isto pode afetar a fauna de insetos. O objetivo foi avaliar, durante 24 meses, abundância de insetos mastigadores, dípteros, polinizadores e predadores em plantas de S. saponaria fertilizadas ou não com lodo de esgoto desidratado, em área degradada. O delineamento experimental foi inteiramente casualisado com dois tratamentos (com ou sem lodo desidratado de esgoto) e 24 repetições, cada uma com uma planta. A abundância de Anastrepha sp. (Tephritidae), Cerotoma sp. (Chrysomelidae), Curculionidae, Musca domestica L. (Muscidae), Mantis religiosa L. (Mantodea: Mantidae), Oxyopidae, Salticidae, Tettigoniidae (Orthoptera) e Teudis sp. (Anyphaenidae) foi maior em plantas adubadas. A abundância de Teudis sp. e Tmarus sp. (Thomisidae) e M. religiosa e Teudis sp. foi, positivamente, correlacionada com as de insetos mastigadores e Diptera, respectivamente. O aumento populacional de insetos e aranhas em plantas de S. saponaria, adubada com lodo desidratado de esgoto (maiores copas), mostra ser adequado para a recuperação de áreas degradadas, tendo essas plantas um maior número de nichos e com alimento de melhor qualidade, melhorando os índices ecológicos na área. recuperálos. recuperálos recuperá los. los recuperá-los L Sapinales (Sapinales Sapindaceae, Sapindaceae , Sapindaceae) degradadas avaliar 2 meses dípteros S degradada repetições planta sp Tephritidae, Tephritidae (Tephritidae) Chrysomelidae, Chrysomelidae (Chrysomelidae) Curculionidae Muscidae, Muscidae (Muscidae) Mantodea (Mantodea Mantidae, Mantidae Mantidae) Oxyopidae Salticidae Orthoptera (Orthoptera Anyphaenidae (Anyphaenidae adubadas Thomisidae (Thomisidae M positivamente Diptera respectivamente maiores copas, copas copas) qualidade (Tephritidae (Chrysomelidae (Muscidae

Abstract The aims of this work were to characterize the damage caused by Paraulaca dives in feijoa (Acca sellowiana) and develop a diagrammatic scale to evaluate the severity of herbivory. The evaluations were carried out in a feijoa progenies orchard with eight-year-old. The beetles caused damage mainly on leaves, from October to December (spring season). The distribution of beetles in the orchard occurred randomly, not following a defined pattern of incidence. The diagrammatic scale of herbivory severity was represented by seven levels (1%, 3%, 5%, 7%, 15%, 32%, and 55% of the leaf area consumed). The use of this diagrammatic scale significantly increased the precision and accuracy of severity estimates by inexperienced evaluators. This can help in strategies to control this pest to expand the cultivation of feijoa in Brazil.
