In this study preferences of the parasitoid Pachycrepoideus vindemmiae Rondani, to different ages of oriental fruit fly, Bactrocera dorsalis Hendel pupae, number of progenies, development time, adult longevity and sex ratio of the parasitoids have been studied. The results showed that P. vindemmiae parasitized pupae of all ages, and the rate of parasitism was high for 3 to 6 days-old pupae. The development time of parasitoid was significantly increased; in 3 to 6 days-old host compared with other age groups. The host mortality decreased with increasing host age. Male progeny developed faster than females, and older host pupae produced a higher proportion of males. Adult longevity of P. vindemmiae offspring were not affected by the age of the pupae. The results suggest that 3 to 6 days-old pupae of B. dorsalis are suitable host ages for P. vindemmiae and can be used for mass rearing P. vindemmiae under laboratory conditions for possible use in integrated pest management.
