Aspectos biológicos de adultos de um parasitóide do bicudo do algodoeiro

bracon sp. is an important biological control agent of anthonomus grandis, the cotton boll weevil. the objective of this work was to evaluate biological aspects of bracon sp. using cotton boll weevil larvae as host, at conditions of 26 ± 2oc, with 70 ± 5% rh and 12h photoperiod. the complete life cycle of bracon sp. was 11.7 days. the incubation period lasted 1.0 day and the larval period 3.9 days with four stages; the viability of the larvae was 98.7%; prepupal period lasted 0.6 day; and the pupal period lasted 6.2 days. preoviposition period was 4.0 days, and the females laid an average of 74.0 eggs with in an oviposition period of 27.2 days, while the average daily oviposition rate was 2.7 eggs per female per day, posovipositional lasted 3.7 days, and the longevity of bracon sp. was 34.0 days in females. the information of the biology of this braconid is needed to develop parasitoid propagation and colonization strategies.
