Descripción
This study aimed to understand the diversity of associated mites in cocoa growing areas in the municipalities of Bragança and Augusto Corrêa, state of Pará, as well as their distribution in rainy and dry periods. A total of 1,178 mites were collected and the most abundant families were Phytoseiidae, Tetranychidae, Tuckerellidae, Iolinidae and Cunaxidae, in addition to the unidentified taxa of the suborder Oribatida. The most abundant species were Oligonychus sp. (13.9%), Tuckerella ornata (12.2%), Amblyseius n. sp. 1 (12.1%) and Parapronematus sp. (10.5%). Among the predatory mites, the phytoseiid mites were more abundant and prevalent, with Amblyseius n. sp. 1 and Armascirus amazoniensis standing out. Amblyseius n. sp. 1 showed greater abundance in the rainy season than in the dry season, in both municipalities. Great diversity did note, mainly for predatory mites, while phytophagous mites were more abundant.
