In the present work, the host-parasitoid system between the Medfly Ceratitis capitata and the oligophagous braconid wasp Psyttalia concolor has been studied to elicit the existance of non-target effects of an azadirachtin-based treatment of the host, on the life-cycle of the parasitoid. Results showed that the braconid wasp was able to normally complete its life-cycle on treated medfly larvae, and to produce fertile offspring. On the other hand, the fecundity and longevity of P. concolor adults showed a significant reduction when insects were directly treated with azadirachtin.
