Resumo
Este trabalho teve como objetivo caracterizar as espécies de ácaros comuns nas diferentes partes do cafeeiro (superfície da folha, domácia, ramos e caule), bem como no solo, folhedo e plantas daninhas. O estudo foi conduzido em cafeeiro no município de Atibaia, Estado de São Paulo. As amostragens foram realizadas mensalmente entre janeiro de 2007 e fevereiro de 2009. As espécies Brevipalpus phoenicis (Geijskes) (Tenuipalpidae), Iphiseiodes zuluagai Denmark & Muma, Proprioseiopsis dominigos (El-Banhawy) (Phytoseiidae), Raphignathus sp. (Raphignathidae) Galumnidae sp.1, Scheloribatidae, Scapheremaeus sp. (Cymbaeremaeidae), Gymnolaelaps sp. (Laelapidae), Exothorhis sp. (Eupallopselidae), Ologamasus sp. 1 (Ologamsidae) e Asca sp.3 (Ascidae) foram comuns aos três substratos estudados (plantas de café, plantas daninhas e folhedo-solo). A ocorrência de várias espécies de ácaros em mais de um substrato indicou uma possível migração desses ácaros de um substrato para outro. Nesse aspecto, algumas espécies de predadores presentes em plantas daninhas, folhedo-solo, poderiam estar auxiliando no equilíbrio populacional de ácaros pragas em cafeeiro.
The objective of this study was to characterize the mite species on different parts of coffee plants (leaf surface and domatia, branches and stem), as well as, on weeds, in litter and soil. The study was carried out in a coffee plantation in Atibaia County, State of São Paulo. The samples were taken monthly, from January 2007 to February 2009. The species Brevipalpus phoenicis (Geijskes) (Tenuipalpidae), Iphiseiodes zuluagai Denmark & Muma, Proprioseiopsis dominigos (El-Banhawy) (Phytoseiidae), Raphignathus sp. (Raphignathidae) Galumnidae sp.1, Scheloribatidae, Scapheremaeus sp. (Cymbaeremaeidae), Gymnolaelaps sp. (Laelapidae), Exothorhis sp. (Eupallopselidae), Ologamasus sp. 1 (Ologamasidae) e Asca sp.3 (Ascidae) were common to the three substrates (coffee plants, weeds and litter/soil. The occurrence of several mite species on more than one substrate indicated a possible migration of mites among the substrates. In this aspect, some species of predaceous mites present on weeds, in litter and soil could be contributing to the population equilibrium of pest mites on coffee plants.
