Three families of phytophagous mites are of economic importance on coffee (Coffea spp.) plantations: Tetranychidae, Tenuipalpidae and Tarsonemidae, with the Phytoseiidae likely to be the main predators of these mites. Several studies indicate that the abundance and diversity of entomophagous arthropods present in a particular crop are closely related to the nature of the surrounding vegetation. In this study, leguminous arboreous species for multiple use, used as windbreak (alley cropping system, hedgerows), were evaluated in relation to phytossanitary aspects of coffee crop. The arboreous leguminous species used as windbreak in the experiments were: Pigeon pea (Cajanus cajan Millsp.), Bracatinga (Mimosa scabrella Benth.), Leucaena [Leucaena leucocephala (Lam.) De Wit] and Acacia (Acacia mangium Willd.), planted perpendicularly to the predominant winds orientation. Leaves were collected from both windbreak and coffee plants each year after the rainy and dry seasons. Wash method was used to remove the mites from the collected leaves. Coffee plants under the influence of Leucaena revealed the highest number of specimens of mites, almost near twice of the total number found in plants under the influence of the remaining alley cropping. The mite families found in coffee plants and in the alley cropping are quite the same, which should be considered beneficial since the eventual use of chemicals for pest control in coffee areas, with resulting reduction in mite population, can have in windbreak a source for replacement, mainly of beneficial ones.
