This study shows the diversity of species of tephritid flies, their parasitoids and hosts in the region of Viçosa, Minas Gerais, located in the Zona da Mata Mineira. McPhail traps containing hydrolyzed protein, were installed in orchards with diverse species of fruit trees and a nature reserve, the Atlantic forest, forest known as the Mata do Paraíso. In addition, collections were made periodically cultivated and wild fruits in the region. Were obtained in 21 species of tephritid collections: Ceratitis capitata (Wied.), Anastrepha bahiensis Lima, A. barbiellinii Lima, A. bezzii Lima, A. bistrigata Bezzi, A. dissimilis Stone, A. distincta Greene, A. fraterculus (Wied.), A. furcata Lima, A. grandis (Macquart), A. leptozona Hendel, A. manihoti Lima, A. minensis Lima, A. montei Lima, A. obliqua (Macquart), A. pseudoparallela (Loew), A. pickeli Lima, A. serpentina (Wied.) and A. sororcula Zucchi, and two new species of Anastrepha. Deposited at the Regional Museum of Entomology (UFVB) found five species of tephritid A. connexa Lima, A. consobrina (Loew), A. kuhlmanni Lima, A. turpiniae Stone and A. xanthochaeta Hendel. 39 species of wild and 22 cultivated plant families sampled, we obtained C. capitata, A. bezzii, A. fraterculus, A. grandis, A. obliqua and A. sororcula. Parasitoids were also collected: Braconidae - Doryctobracon areolatus (Szépligeti), D. brasiliensis (Szépligeti), Opius bellus Gahan, Utetes anastrephae (Viereck) Figitidae - Aganaspis pelleranoi (Brèthes) and Pteromalidae - Sycophila sp.1, Sycophila sp.2, Torymus sp. and Pteromalidae sp.3. A taxonomic key for identification of species collected in Viçosa region is presented. An analysis for the fauna of Tephritidae species collected in the region of Viçosa, Minas Gerais. Assessing the population dynamics of three species was also performed, taking into account the influence of temperature, relative humidity and rainfall in addition to the dominance of these survey sites. Through this study added 19 species of fruit flies in Viçosa, Minas Gerais, bringing to 32 species of tephritid in Minas Gerais. Anastrepha barbiellinii, A. connexa, A. consobrina, A. furcata, A. kuhlmanni, A. leptozona and A. xanthochaeta were found first for the state and two new species of Anastrepha findings. Anastrepha fraterculus was the most frequent species in the samples of infected hosts and first observed occurrence in Lauraceae, Solanaceae Siparunaceae and in Brazil. The association of A. obliqua with tangerine and Ponkan cambucá and A. fraterculus with sweet cherry and passion fruit was also first observed through this study. The four species of parasitoids the Pteromalidae family, Sycophila sp.1, Sycophila sp.2, Torymus sp and a fourth species of Pteromalidae not yet identified, are new records for the state, passing 12 species of parasitoids of fruit flies in Minas Gerais. The population fluctuation of Anastrepha fraterculus and Ceratitis capitata in the region of Viçosa was influenced by temperature. Anastrepha minensis population fluctuation was influenced by temperature and precipitation. Fruticultura/Campus and Fruticultura/Fundão were more similar environments for the presence and absence of species of fruit flies (43%) while the small farm the environment was less similarity in terms of presence and absence of species (31 %).
