Abstract : The study was done during th period of June 2007 to January of 2008, in commercial mango orchards having: 3 ha of cv. Tommy Atkins, 3 ha of cv. Haden. and 3 ha of cv. Palmer, located at Bom Intento in the municipal district of Boa Vista-RR. The specimens of fruit flies were collected, by trapping, made with transparent bottles pet, which were hung in the cup of the trees at 1.60 m of height. 200 mL of passion fruit juice (30%) was used as an attractant feed; 9 traps were used, being one trap for hectare. Weekly The traps were examined weekly, during which the bait was substituted and the captured insects removed, placed in labeled glass flasks properly and transported to the Laboratory of Entomology, Centro de Ciências Agrárias, Universidade Federal de Roraima - UFRR. The identification of the specimens was done at the Instituto Nacional de Pesquisa da Amazônia-INPA. During the period of eight months 24 adult specimens of Anastrepha were collected (9 females and 15 males). Four species were identified: A. serpentina, A. striata, A. obliqua and A. turpinae. The highest frequency of trapped insects was A. serpentina (44.44%), followed by A. striata and A. obliqua with 22.22%, and A. turpinae with 11.11%. The months of highest occurrence of Anastrepha spp., were June, July, and August. This is the first documentation of the specie Anastrepha turpinae Stone, 1942, in Roraima.
