    Abstract : There is little information about the fauna of predatory mites (Phytoseiidae) in Brazilian natural environments, adjacent to coffee agroecosystems (Coffea spp.), or about the influence exerted by neighbor vegetation as a reservoir of predatory mites. The objective of this study was to evaluate the diversity of these organisms in coffee plantations and adjacent forest fragments. Samples of the species Calyptranthes clusiifolia (Miq.) O. Berg (Myrtaceae), Esenbeckia febrifuga (A. St.-Hil.) A. Juss. ex Mart., Metrodorea stipularis Mart. (Rutaceae) and Allophylus semidentatus (Miq.) Radlk. (Sapindaceae) were collected in eight forest fragments, from 5 to 51 ha, adjacent to coffee plantations, in June (end of the rainy season) and October (end of the dry season) in the years of 2004 and 2005, in the Southern region of State of Minas Gerais. Leaf mites were extracted using the wash method, mounted in microscopy slides with Hoyer's medium for identification. A total of 2.348 phytoseiids was collected, being 2.090 in the forest fragments and 258 in adjacent coffee plantations, belonging to 38 species. According to fauna analysis, Iphiseiodes zuluaguai Denmark & Muma, the year of 1972 presented the best indexes in the coffee agroecosystem, being very frequent and constant in those periods. In the forest fragments, Amblyseius herbicolus Chant, 1959, Iphiseiodes affs. neonobilis Denmark & Muma, 1978, Leonseius regularis DeLeon, 1965 and Euseius alatus DeLeon, 1966 were dominant, very abundant, very frequent and constant in those periods. One may conclude that the native vegetation shelters predator mite, natural enemies of mite-pests that still occur in coffee culture, making possible ecological management program development involving areas of natural vegetation and adjacent coffee agroecosystems.
