We evaluate the occurrence of Anastrepha in three areas with different anthropization levels: guava monoculture, polyculture, and native forest in the municipality of Barreiras, Bahia, Brazil. We collected the occurrence data using thirty McPhail traps, which were evenly distributed in the areas. Fifteen collections were carried out weekly between January and May 2021. We observed a significant difference in means of Anastrepha occurrence between the polyculture area (4.133 ± 1.586) and the other areas. Regarding the area of monoculture of guava (1.286 ± 0.663) and the native forest (0.740 ± 0.283), we observed no significant differences.
