Presence of native forest showed a detrimental effect on the colonization and distribution of Anastrepha fraterculus (Wied.) adults in apple (Malus domestica) orchard but not in the peach (Prunus persicae) orchard. In apple, adults began to occupy the orchard in arcas adjacent to the forest, and concentrated its presence in the forest and surroundings. In peach, 90.5% of the flies were captured within the orchard, and only 0.5% in the forest or nearby. Within the apple orchard, 43.0% of the flies were captured, and the first flies invading the habitat were females, while in peach both sexes occurred simultaneously, especially females. It was possible to characterize a pattem of adult colonization and distribution in peach and apple agroecosystems. In peach, fruit presence (especially dose to ripening) had a positive correlation with adult occurrence and distribution, while in apple this did not occur.
