Resumo. Em Manaus, o processo de desenvolvimento industrial e sócio-econômico, bem como a falta de programas eficientes de controle ambiental tem possibilitado a ocorrência de impactos ambientais especialmente nos igarapés urbanos. Estes impactos resultam na degradação dos recursos hídricos por meio de poluentes orgânicos e inorgânicos oriundos das atividades desenvolvidas no entorno das bacias hidrográficas. Objetivou-se então analisar os teores dos metais cobre e zinco em náiades de C. anceps. O estudo foi realizado em dois afluentes na Bacia do Educandos: o primeiro, foi feita a coleta de C. anceps, está situado na Universidade Federal do Amazonas e, o segundo, foi feita a coleta da água contaminada, igarapé do Quarenta, está situado nas proximidades de fábricas do Distrito Industrial de Manaus. As náiades coletadas no igarapé universidade (água limpa) foram levadas ao laboratório de entomologia, no INPA, onde foram expostas a água contaminada do igarapé do Quarenta , nas concentrações de 100%, 50% ,10% e um controle com 100% de água limpa. As C. anceps ficaram expostas a esses poluentes por seis dias. Com três e seis dias foram retiradas para a análise dos metais, no laboratório de química da água. Os teores desses nos mostraram que há uma absorção deste pelas náiades, pois quanto maior a concentração dos metais na água, maior será o valor encontrado nos organismos.Bioassay with nymph of Campylocia anceps Eaton, 1983 for evaluation of metals copper (Cu) and zinc (Zn).Abstract. In Manaus, the process of industrial and partner-economic development, as well as the lack of efficient programs of ambient control has made possible the occurrence of ambient impacts especially in narrow river urban. These impacts result in the degradation of the hidrics resources by means of deriving organic and inorganics pollutants of the activities developed in around of the basins hidrografics. It was objectified then to analyze texts of metals couper and zinc in nymphs of C. anceps. The study it was carried through in two narrow rivers in the Basin of the Educandos: the first one, was made the collection of C. anceps, is situated in the Federal University of Amazon and the collection of the contaminated water was made, narrow river of the Quarenta, is situated in the neighborhoods of plants of the Industrial District of Manaus. Nymphs collected in the narrow river university (clean water) had been taken to the entomology laboratory, in the INPA, where they had been displayed the water contaminated of the narrow river of the Quarenta, in the concentrations of 100%, 50%, 10% and a control with 100% of clean water. The nynfphs of C. anceps had been displayed to these pollutants per six days. With three and six days they had been removed for analyzes of metals, in the chemistry laboratory of the water. The texts of these in had shown them that it has an absorption of this for nymphs, therefore how much bigger the concentration of metals in the water, greater will be the value found in the organisms.

Herbet Tadeu de Almeida Andrade | Alexandre S. Santiago | Jansen Fernandes Medeiros
Esse trabalho teve como objetivo conhecer os invertebrados bentônicos, bem como caracterizar os grupos tróficos funcionais existentes no rio Piranhas-Assu, município de Alto do Rodrigues, Rio Grande do Norte. As coletas foram realizadas nos meses de maio (chuva), julho e setembro (seca) de 2002, em trechos diferentes do rio. Foi medida a velocidade da correnteza, a largura, profundidade do rio e temperatura da água. Foram coletados 3525 indivíduos de Insecta e outras classes (Malacostraca, Gastropoda, Bivalvia, Arachnida, Ostracoda e Copepoda). A maior abundância da classe Insecta ocorreu no mês de setembro (seca). A vazão apresentou correlação com a abundância com na Classe Insecta, já a velocidade superficial da água para outras classes. Entre os Insecta observou-se uma maior abundância de predadores, seguida dos coletores, já para as outras classes os raspadores foram mais abundantes. Structure of benthic invertebrate’s community with focus in the aquatic insects of the Piranhas-Assu river, State of Rio Grande do Norte, Northeast, Brazil Abstract. The aim of this work was to verify the benthonic invertebrates, and to identify the functional trophic groups that exist in the Piranhas-Assu, in Alto do Rodrigues municipality, Rio Grande do Norte State. The samples were carried taken on May (rain season), July and September (dry season) from 2002, in different sites in the river. The measurements of water speed, wide, temperature and river deep where made. It was collected 3525 individuals of Insecta and other classes (Malacostraca, Gastropoda, Bivalvia, Arachnida, Ostracoda and Copepoda). Insecta showed a higher abundance in September (dry season). The river discharge showed significant correlation with Insecta classe abundance, and the superficial water speed had correlation with other classes. The insects showed a highest abundance of predators, followed by collectors, in the other classes, the scrappers were the most abundant.

Solitary wasp nests (Sphecidae) are often occupied by other arthropods when abandoned. However, occupation by ants such as Cephalotes Latreille, 1802 is still uncertain. Species of Cephalotes are arboreal and occupy pre-existing cavities, commonly tree hollows. In this respect, the objective of this study is to report the first record of the ant Cephalotes pusillus (Klug, 1824) (Hymenoptera: Formicidae) nesting in a Sphecidae nest in areas cultivated with coffee, Coffea arabica L. The nest was collected on july 5, 2024, in a coffee plantation area in the municipality of Inconfidentes, Minas Gerais, Brazil. This area is associated with a fragment of Atlantic Forest. In the nest of Sceliphron sp. (Hymenoptera: Sphecidae), 64 pupae, 94 adults and four queens of the ant were counted. The successful occupation by the ant may have occurred due to different factors, such as the size and resistance of the nest, the size of the entrance and the multiple cells that are formed inside the nest, which allowed the use of this nest as an incubation site for the ant's larvae. This is the first record of C. pusillus nesting in a Sphecidae nest, but this species is a generalist in terms of the cavities it uses, requiring further observations to confirm the frequency of this behavior.

2025
Marcos Aragão | Emanuelle Luiz da Silva Brito
Social wasps (Vespidae: Polistinae) are highly adaptable insects that exploit a wide range of locally and seasonally available resources. This study reports the first observation of social wasps foraging on noni fruit (Morinda citrifolia L.) in Northeast Brazil, specifically in the Caatinga biome. Noni, a pantropical fruit known for its environmental tolerance and nutritional content, including high water and protein levels. Seven species of social wasps were recorded foraging on noni in the rural area of Patos, Paraíba state, Brazil. These species included Polybia ignobilis, Polybia occidentalis, Polybia paulista, Polybia sericea, Brachygastra lechiguana, Protonectarina sylveirae, and Polistes canadensis. Observations revealed that the wasps foraged primarily on the carpel disc of the fruit, engaging in scraping behavior to extract juices and soft tissues. No activity was observed on ripe fruits, likely due to their strong odor. The findings highlight the ecological importance of noni fruits as a resource for social wasps, particularly in arid regions as Caatinga biome where such fruits provide essential nutrients.

Gabriel Vila-Verde | Jacques Hubert Charles Delabie
The Brazilian endemic butterfly Eresia erysice erysice (Geyer, 1832) (Lepidoptera: Nymphalidae) has been included in the Official List of Brazilian Endangered Fauna as critically endangered (CR). Until now, this rare butterfly has only been known to inhabit Atlantic Forest fragments in the “Hileia Baiana”. This paper presents updated information on occurrences of E. e. erysice. A male and a female specimens were collected in a disturbed forest fragment near the experimental fields of the Centro de Pesquisas do Cacau (CEPEC), Ilhéus, Bahia. These new findings indicate that the distribution boundary of this subspecies extends about 80 km more to the north and suggest that it is not as exclusive to forest habitats as previously thought.

The Cerrado and Atlantic Forest biomes are global biodiversity hotspots. However, these environments still face large knowledge gaps concerning fauna inventory studies, such as those on harvestmen. Our study aimed to sample harvestmen species in a transition area between the Atlantic Forest and Cerrado, contributing to future biodiversity assessments and conservation efforts in Brazil. The surveys were conducted in the municipality of Luminárias, southern Minas Gerais state, between May 2023 and March 2024. We collected 185 individuals from six species and three morphospecies with a wide geographical distribution, but whose conservation status has not been assessed, which may affect their protection. Additionally, loss of native vegetation may lead to reductions in their populations. Our study supports current literature, which suggests the need for more inventories and the creation of a Conservation Unit in the Luminárias region.
