| Studies were conducted in laboratory to evaluate the toxicity of three insecticides (imidacloprid, fipronil and natural pyrethrins+piperonyl butoxide) to pupae and adults of Hyposoter didymator and Chelonus inanitus, both of them solitary endoparasitoids of several noctuid larvae. Topical application on pupae, and residual, topical and ingestion bioassays on adults of the two parasitoids, at field rates, were used to assess percentages of adult emergence and life span, in case of treated pupae and life span for adults. Out of the three compounds tested, only fipronil reduced significantly the life span of emerged adults after topical treatment of H. didymator and C. inanitus pupae (90 and 75%, respectively). The life span of treated adults at field rates were significantly reduced on both parasitoids by all the insecticides tested irrespective of the uptake route, with the exception of C. inanitus adults treated with imidacloprid. Fipronil was clearly the most toxic insecticide. | |
