Biology of Diachasmimorpha longicaudata (Hymenoptera: Braconidae) Reared on Third Instar Larvae of Bactrocera dorsalis (Diptera: Tephritidae)

Abstract

The biology of Diachasmimorpha longicaudata (Ashmead) was studied on third instar larvae of Bactrocera dorsalis (Hendel) to optimize its mass rearing in the laboratory. The mean parasitoid emergence rate ranged from 55–92% during its first 13 days of life. The number of females was higher than that of males. The mean development time from egg to adult emergence was 20.14± 0.02 days in females and 17.72± 0.02 days in males. Fed females lived longer than fed males. Food-deprived females and males lived 72 hr after emergence. The lifespan of males and females was 16.42± 0.53 and 15.86± 0.35 days, respectively, in pairs exposed to B. dorsalis larvae.
