The aim of this study was to identify the mite fauna associated with cupuaçu plantations in Bragança and Augusto Corrêa, Pará, Brazil. In order to investigate the variability and composition of these organisms in cupuaçu plantations in two different locations, systematic collections were carried out at specific times throughout two periods. In addition to mite collection, environmental data such as temperature, relative humidity, atmospheric pressure and precipitation were recorded. Statistical data were obtained through sampling effort and diversity, Hill's diversity profile and nonmetric multidimensional scaling (NMDS). A total of 868 mites belonging to 53 species were sampled. Seventeen families/suborders of mites were identified, the five most abundant being: Eriophyidae (44.7%), Phytoseiidae (21.1%), Cunaxidae (9%), Oribatida (5.5%) and Tenuipalpidae (3.5%). The data indicated a greater number of mites sampled during the rainy season compared to the dry season, representing approximately 90% more mites in the rainy season. Greater richness was observed during the dry season, with 38 taxa identified. Bragança contributed a total of 551 individuals, while Augusto Corrêa recorded 317 mites. For the Shannon- Wiener index, the municipalities presented similar diversity. Therefore, we highlight the importance of these results for understanding the mite community associated with cupuaçu trees.
