Abstract : The indigenous eucoilid Aganaspis pelleranoi (12.2%), and the braconids Doryctobracon areolatus (81.4%), Utetes anastrephae (0.7%) and Opius spp. (0.7%), plus the foreign species Diachasmimorpha longicaudata [Biosteres longicaudatus] (5.0%), were identified parasitizing fruit fly [Tephritidae] larvae in Conceição do Almeida, Bahia, Brazil. Fruit samples were examined from September 1995 to September 1996 in fallen ripe fruits of guava (Psidium guajava), surinam cherry (Eugenia uniflora), carambola (Averrhoa carambola) and mangoes (Mangifera indica). The final parasitism of viable pupae was 7.4%, 43.9%, 10.2% and 19.0%, respectively. D. areolatus was detected in higher numbers in all fruits, except in guava. D. longicaudata was also sampled in all fruits. Surinam cherry was the fruit from which the highest number of parasitoids emerged (1.512 from 4.239 collected fruits). A. pelleranoi was the predominant parasitoid in guava.
