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
