RESUMO
This paper deals with a survey and identification of soil ant species (Hymenoptera, Formicidae) occurring in organic coffee (Coffea arabica) crop in order to determine species richness and diversity, as well as the ant species to be used as bioindicators of habitat disturbance in the coffee agroecosystem. Two experiments were set in an organic coffee (Coffea arabica) plantation in Dois Corregos, State of São Paulo, Brazil, one in rainy season (experiment I, February/2008) and other in the dry season (experiment II, July/2008). The ants were collected by using Pitfall trap and Winkler trap and the material was brought to the laboratory were the ant species were identified. There were two coffee areas: sun exposed crop and shadowed crop. One collected 7.101 specimens distributed in 38 species. Few species were constant and frequent ones along the research: Collect I-sun exposed and Collect II-shadowed crop, according to Shanon- Wiener and Simpson indices. The only point to present high dominance was observed in Collect I-sun exposed. One conclude that Linepthema humile is the ant species to be used as bioindicator of habitat disturbance in the organic coffee.
