Weekly, were collected systematically fruit flies through trap type McPhail and ripe fruit and in ripening one, on those orchards. Were collected 7.016 tephritid obtained from trap (5.226) and fruit (1.790), from which 1.044 belonged to genus Anastrepha and 5.972 were Ceratitis capitata. The specimens number of C. capitata (85.1%) was around six times superior to Anastrepha spp. (14.9%), demonstrating the preference of this species for urban orchards. Eight species of Anastrepha occur in urban orchards of Janaúba, MG. Ceratitis capitata was found infesting 10 species of host fruits, being the main S. purpurea and guava. In fruits were collected three species of Anastrepha (A. obliqua, A. sororcula and A. zenildae) which were associated with five species of fruit (Malpighia glabra L, Psidium guayava L, S. dulcis, S. purpurea and S. tuberosa). The predominant species of Anastrepha was A. obliqua, and S. tuberosa and S. purpurea being the main hosts of this species in the urban area of Janaúba, MG.
