Abstract
Mango ( Mangifera indica L. ) production has expanded greatly in Brazil but several pests, especially fruit flies, have limited both fresh fruit consumption and exports. Insect surveys are important in insect ecology, biology and control. From September 1999 to February 2000, ten mango varieties were surveyed for insects and level of natural fruit infestation in three counties of Goias. A total of 1195 pupae were obtained. Of the total adults, 80% were Anastrepha (484), 17.2% Lonchaeidae (104) and 2.8% Braconidae (17). Females belonging to Anastrepha genus and Neosilba genus represented 70.3% and 29.7%, respectively. Four Anastrepha species were identified: A. obliqua (48.78%), A. fraterculus (47.97%), A. sororcula (2.03%) and A. turpiniae (1.22%); the latter species reported for the first time attacking mangoes in Goias. Doryctobracon areolatus was obtained from Imperial and Tommy Atkins mango varieties and was described for the first time attacking mangoes in Goias. Imperial and Tommy Atkins were the most susceptible varieties with the highest infestation levels (15.3 pupae/fruit and 7.0 pupae/fruit, respectively). Bourbon had no infestation and Sabina was slightly infested (0.363 pupae/fruit). KEY-WORDS: Insecta; Diptera; Tephritoidea; damage; parasitoids.
