We studied the community of fruit flies in an agricultural habitat (guava orchards) and the adjoining native vegetation, in a caatinga-cerrado transition region in the state of Minas Gerais, Brazil. Sampling was conducted with McPhail traps and by collecting guavas and other fruits in native vegetation. The 3 most common fruit-fly species in the orchards were Anastrepha zenildae Zucchi, A. sororcula Zucchi, and A. fraterculus (Wiedemann), whereas the most common species in the forest fragments were A. zenildae, A. pickeli Lima, and A. montei Lima. The species of fruit flies recorded in the forests were also collected in the guava orchards. Species of economic importance, such as A. zenildae, use forest fruits as alternative hosts. Fruit-fly diversity is supported by the presence of native vegetation fragments adjacent to agricultural areas.
A comunidade de moscas-das-frutas foi estudada em áreas constituídas por um pomar de goiaba ao lado de um fragmento de vegetação nativa, localizadas em uma região de transição caatinga-cerrado no estado de Minas Gerais, Brasil. As coletas foram realizadas com armadilhas McPhail e pela coleta de goiaba e de frutos nativos. As três espécies de moscas-das-fruta mais comuns nos pomares foram Anastrepha zenildae Zucchi, A. sororcula Zucchi e A. fraterculus (Wiedemann), enquanto as espécies mais comuns nos fragmentos florestais foram A. zenildae, A. pickeli Lima, e A. montei Lima. As espécies de moscas-das-frutas observadas nos fragmentos de vegetação nativa também foram coletadas em pomares de goiaba. As espécies de importância econômica, como A. zenildae, usa frutos da mata como hospedeiros alternativos. A diversidade de moscas-das-frutas é sustentada pela presença de fragmentos de vegetação nativa adjacentes às áreas agrícolas.
