The corn leafhopper Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Cicadellidae) is a specialist insect vector of the corn stunting disease complex. This leafhopper has been reported from different overwintering plants, and more information is required regarding other potential Brazilian plants that may serve as reproductive hosts for this specie. The present study aimed to evaluate possible plants for leafhopper reproduction usually found near the maize fields and the D. maidis reproductive differences among maize genotypes. Three trials were conducted to assess D. maidis survival and oviposition on different maize genotypes and other potential host plants. Survival, nymph presence, oviposition, and nymph eclosion rates were observed. No nymphs were observed in plants other than maize. The number of D. maidis adults was influenced by the different maize inbreds, and the mean number of laid eggs varied across the tested maize materials. Oviposition and nymph emergence was observed in pearl millet [Pennisetum glaucum (L.) R. Br., Poaceae] when D. maidis adults were offered only this plant as substrate, although significantly lower than those recorded on maize. Our results suggest that eliminating maize plants in the off-season could be used as a tool to reduce D. maidis reproduction, thereby minimizing the vector population size in the following season.

The Neotropical genus of stingless bees Melipona Illiger, 1806 is exclusive to Tropical America and has its greatest diversity in South America, with about 74 described species. In Bahia, there is an occurrence record for 12 species of Melipona, distributed in four subgenera. Among the Melipona (Melikerria) that occur in Bahia, we highlight Melipona (Melikerria) quinquefasciata Lepeletier, 1836. Although widely distributed in Brazil, its underground nesting habit associated with its preference for high altitude areas, make the species extremely vulnerable. This work sought to describe nests and map the occurrence of this species for the State of Bahia, since its record is limited to areas of Chapada Diamantina. Knowledge about the biogeography of the species is extremely important, strengthening its sustainable creation that respects the area of occurrence of the species, as well as seeking alternatives and public policies for sustainable conservation, since its area of occurrence is extremely vulnerable to the expansion of the agricultural frontier in the State.

Lonomia Walker, 1855 is a genus of Lepidoptera belonging to the Saturniidae whose caterpillars have a defense system based on scoli connected to venom glands, which can cause medical accidents of envenomation, thereby making this genus medically important. In this work, Lonomia camox Lemaire, 1971, is recorded for the first time in Brazil, more specifically in the state of Amazonas. Photographs of male and female genitalia and an updated map with new occurrence records are presented.

This study was conducted at the Universidade Estadual de Mato Grosso do Sul, Cassilândia, Brazil from September 2017 to December 2021 in a Brazilian Cerrado. Adults of Anomala testaceipennis Blanchard were collected associated with host plants and taken to the laboratory for studies. Some phytophagous scarab beetles found host plants through detection of plant volatiles. The detection of those odorants is intermediated by antennal sensilla. The main goals of the present study are to describe the antennal sensilla of A. testaceipennis and check the host plants used as food resource. This specie was found feeding on flowers of: Anadenanthera colubrina var. cebil (Fabaceae), Azadirachta indica (Meliaceae), Buchenavia sp. (Combretaceae), Cordia glabrata (Boraginaceae), Inga edulis (Fabaceae), Moquilea tomentosa (Chrysobalanaceae), Paubrasilia echinata (Fabaceae), Tabernaemontana catharinensis (Apocynaceae), Tapirira guianensis (Anacardiaceae), Xylophragma pratense (Bignoniaceae). To the sensilla study, antennae were dissected and images of the sensilla were obtained using a scanning electron microscope. Antennae of A. testaceipennis have sensilla chaetica, trichodea, placodea (type I, II, and III), coeloconica (type I and II), basiconica (type I), and ampullacea (or pore). Males have a total of about 6,243 sensilla of which 5,868 (93.99%) are sensilla placodea, 370 (5.93%) are sensilla coeloconica, and 5 (0.08%) are sensilla basiconica. Females have a total of about 5,119 sensilla of which 4,820 (94.16%) are sensilla placodea, 270 (5.27%) are sensilla coeloconica, and 29 (0.57%) are sensilla basiconica.

Tabanidae Latreille are hematophagous and act as mechanical and biological vectors of several pathogens, and therefore they have been widely studied in both ecology and public health, as well as in taxonomy works. Males are nectarivorous and rarely captured, so for most species they remain unknown. Thus, we aimed to describe/redescribe the males of five species: Esenbeckia osornoi Fairchild, 1942, Acanthocera marginalis Walker, 1854, Dicladocera mutata Fairchild, 1958, Stypommisa aripuana Fairchild & Wilkerson, 1986, and Tabanus mucronatus Fairchild, 1961. Three males are described for the first time and two others are redescribed, we also provide a complete description of the species, including photographs of habitus, head and genitalia.

The foraging activity of floral visitors is influenced by habitat conditions and abiotic factors. The aim of this research was to define the faunal composition of the visitor community in Solanum lycocarpum A.St.-Hil. (Solanaceae) and to evaluate the influence of abiotic factors on the flight activity of the predominant visitors. The capture of bees was conducted for 15 minutes from the beginning of each hour between 6:00 am and 6:00 pm in a cluster with 15 S. lycocarpum individuals during 10 days. Centridini was the predominant tribe of bees, with 83.5% of the total foraging recorded. About 66.5% of foraging was concentrated in the time interval between 8:00 am and 12:59 pm, characterized as a optimal foraging period. At 6:00 am and from 5:00 pm onwards, bees were discouraged from foraging. Only Epicharis flava Friese and Centris scopipes Friese were classified as predominant species. Centris scopipes was the only predominant species whose abiotic conditions interfered in the foraging activities. Since bee foraging records were developed in the summer, environmental conditions did not limit the foraging of most bees during the entire foraging period of the day.

The present research aimed to study the functional groups of ants in organic and conventional cropping areas and assess their influence on the abundance of other insects in agroecosystems. Sampling was carried out in eight rural properties with organic, and eight with conventional crops in Paraíba do Sul, state of Rio de Janeiro, Brazil. Fifteen pitfall soil traps were installed to collect ants in each property, in April and May 2016. The ants collected were dry-mounted and identified. The insect abundances of the orders Coleoptera, Hemiptera, and Orthoptera were also obtained. Ants were classified into seven functional groups. The functional group with the largest number of species was “omnivores that inhabit the soil and the leaf litter,” followed by “omnivores that inhabit the soil, the leaf litter, and the plants.” The group “omnivores that inhabit the soil and the leaf litter” showed the highest abundance of ants in both types of crops. The mean richness of functional groups was significantly higher in organic than in conventional crops. We only observed the effect of the abundance of ants of the group “omnivores that inhabit the soil, the leaf litter, and the plants” on the abundance of coleopterans in conventional crops. Hence, areas with organic crops are more favorable for maintaining an ant fauna with higher functional diversity than areas using the conventional cropping system.
本研究旨在研究有机种植区和常规种植区蚂蚁的功能群，并评估其对农业生态系统中其他昆虫丰度的影响。在巴西里约热内卢州Paraíba do Sul的8个种植有机作物的农村和8个种植传统作物的农村进行了抽样。在2016年4月和5月，在每个物业安装了15个陷阱土壤陷阱来收集蚂蚁。采集的蚂蚁被干装并鉴定。对鞘翅目、半翅目和直翅目昆虫的丰度进行了分析。蚂蚁被分为七个功能类群。物种数量最多的功能类群是“栖息于土壤和凋落叶的杂食动物”，其次是“栖息于土壤、凋落叶和植物的杂食动物”。“栖息在土壤和凋落叶中的杂食动物”组在两种作物中都显示出最高的蚂蚁丰度。有机作物的平均官能团丰富度显著高于常规作物。我们只观察了“居住在土壤、凋落叶和植物中的杂食动物”群体中蚂蚁的丰度对传统作物中鞘翅目动物丰度的影响。因此，种植有机作物的地区比种植传统作物的地区更有利于维持具有更高功能多样性的蚁群。

Formigas foram amplamente utilizadas, porém formas de diferentes bioindicadores de ninhos e grupos de igualidade de habitat podem responder diferentemente a um processo ecológico e impacto ambiental. Neste estudo, avaliamos se o estrato do ninho e afinidade de habitat são importantes na resposta de assembleias de formigas ao deslocamento floresta-pastagem. Testamos a resposta de espécies em assembléias inteiras de formigas do solo e únicas faunas (superfície do solo e da fauna única) e de cada formigas (superfície do único número de fauna única). Em ambos os casos, também testamos a resposta do número de espécies de cada grupo de afinidade de habitat (especialista, especialista em habitat e generalista).Formigas foram amostradas em três parcelas para cada tipo de habitat no sudoeste da Amazônia brasileira. Amostramos 124 espécies de formigas. Apenas para assembléias de formas de superfície do solo, o número de espécies foi diferente entre os dois tipos de habitat, entre os grupos de formas de número de habitat e seu número de espécies também mudou com a mudança de habitat. Portanto, corroboramos a inclusão de amostras diferentes de estratos de ninhos e recomendamos a classificação de formas de acordo com sua identidade de habitat que utilizem formas de monitoramento como bioindicador. No entanto, os exercícios devem ser feitos para melhorar a disponibilidade de habitat das espécies de formigas.

Neste estudo, avaliamos se o estrato do ninho e afinidade de habitat são importantes na resposta de assembleias de formigas ao deslocamento floresta-pastagem. Testamos a resposta de espécies em assembléias inteiras de formigas do solo e únicas faunas (superfície do solo e da fauna única) e de cada formigas (superfície do único número de fauna única). Em ambos os casos, também testamos a resposta do número de espécies de cada grupo de afinidade de habitat (especialista, especialista em habitat e generalista).Formigas foram amostradas em três parcelas para cada tipo de habitat no sudoeste da Amazônia brasileira. Amostramos 124 espécies de formigas. Apenas para assembléias de formas de superfície do solo, o número de espécies foi diferente entre os dois tipos de habitat, entre os grupos de formas de número de habitat e seu número de espécies também mudou com a mudança de habitat.
