They play essential ecological roles by providing habitat and food for a multitude of species, as well as contributing to coastal stabilization, reducing soil erosion, and protecting the region from natural phenomena. In Brazil, mangroves cover approximately 13,000 km² and are considered dynamic environments conducive to the survival of countless organisms, including insects. This group, the most diverse in the world, accounts for 60% of all registered species and occupies almost every niche. Within the class Insecta, the most abundant and diverse order is Coleoptera, popularly known as beetles. Their main characteristic is the presence of elytra (hardened forewings) and a highly sclerotized body. Various trap models exist for capturing these animals, including light traps, which are very efficient since many groups exhibit positive phototaxis. Despite their ecological importance and richness, knowledge about the diversity of nocturnal beetles, especially in environments like mangroves, still has numerous gaps. Thus, the objective of this study is to conduct an inventory of the nocturnal beetle fauna in four tidal channels within the mangrove area of the Ajuruteua Peninsula, in Bragança, Pará, using light traps. The results were also compared with studies that used light traps in other ecosystems, and it was observed that the Scarabaeidae family was present in a significant portion of the analyzed environments, possibly due to its high adaptability to diverse habitats and feeding habits. Statistical analyses of diversity, evenness, dominance, and similarity were performed for each collection point, one for genera and another for families. Through this research, 788 specimens were collected and identified to the family and/or genus level. The families with the highest abundance were Curculionidae with 314 specimens, followed by Staphylinidae with 225. The analyses showed that each point has a quite different composition, despite being part of the same mangrove area. The results contribute to a better understanding of the beetle fauna of the Ajuruteua mangrove, and the continuation of studies like this is indispensable to broaden knowledge about the local biodiversity.Acesso AbertoManguezalArmadilha LuminosaInsetoBesourosInventárioMangroveLight TrapInsectBeetlesInventoryCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivatives 4.0 International
