FRUIT FLIES (DIPTERA: TEPHRITIDAE) AND THEIR PARASITOIDS IN HOST PLANTS FROM THREE COUNTIES OF THE NORTH OF MINAS GERAIS STATE, BRAZIL

ABSTRACT

This fruit-fly species survey was based on fruits sampled at several sites (urban and rural areas) in the counties of Jaíba, Janaíba and Nova Porteirinha, in Minas Gerais State, Brazil over a 50-month period (from May 1999 to April 2001 and from June 2002 to July 2004). Thirty-two fruit species in 17 families were sampled, but fruit flies emerged from only 18 host-fruit species. Ceratitis capitata(Wied.) and eight Anastrepha species – A. fraterculus (Wiedemann), A. obliqua (Macquart), A. sororcula Zucchi, A. turpiniae Stone, A. zenildae Zucchi, A. pickeli Lima, A. montei Lima and Anastrepha n.sp.3 – were collected. Medflies emerged mostly from introduced fruits and were predominant in the urban areas, while the Anastrepha species were predominant in the rural areas. Spondias tuberosa Arr. Câm. (“umbu”) and Psidium guajava L. (guava) were the hosts most infested by tephritid larvae. Seven fruit-fly parasitoid species were collected: Doryctobracon areolatus (Szépligeti) (more abundant), D. fluminensis (Lima), D. brasiliensis (Szépligeti), Opius bellus Gahan, Utetes anastrephae (Viereck), Diachasmimorpha longicaudata (Ashmead) and Aganaspis pelleranoi (Brèthes).
