ABSTRACT
Anastrepha species have been recorded from only three states, Amazonas, Para, and Roraima. Samples of 35 host fruit species belonging to 24 genera and 17 families were collected at three sites in Manaus and in Iranduba, Amazonas state, during the 1991/92 fruit seasons. Of the 35 host species collected, 27 are native to South America or the Antilles and eight are exotic, probably introduced from Africa, Europe, and Asia. Nine fruit fly species were reared: Anastrepha antunesi Lima, A. bahiensis Lima, A. distincta Greene, A. fraterculus, A. leptozona Hendel, A. manihoti Lima, A. obliqua, A. serpentina, and A. striata Schiner. The pomology in the Brazilian Amazon is characterized particularly by native fruits. Of almost 180 known fruit tree species in the Brazilian Amazon, one-half are wild and serve as natural repositories for the fruit flies. The highest number of fruit species attacked by fruit flies belonged to the Myrtaceae, of which nine were native species.
