Fruit fly parasitoids associated with tropical fruits

The indigenous species of hymenoptera Aganaspis pelleranoi (Brèthes) (Eucoilidae) (12.2%), and the braconidae Doryctobracon areolatus (Szépligeti) (81.4%), Utetes (Bracanastrepha) anastrephae (Viereck) (0.7%) and Opius spp. (0.7%), plus the foreing specie Diachasmimorpha longicaudata (Ashmead) (5.0%), were identified parasiting fruit fly larvae in Conceição do Almeida, BA. Fruit samples were examined from September 1995 to September 1996 in fallen ripe fruits of guava (Psidium guajava L.), surinam cherry (Eugenia uniflora L.), carambola (Averrhoa carambola L.) and mangoes (Mangifera indica L.). The final parasitism of viable pupae was 7.4%, 43.9%, 10.2% and 19.0% respectively. D. areolatus was detected in higher number in all fruits, except in guava. D. longicaudata was also sampled in all fruits. Surinam cherry was the fruit from which emerged the highest number of parasitoids (1.512 from 4.239 collected fruits). A. pelleranoi was the predominant parasitoid in guava.
