The impacts of indole-3-acetic acid (IAA) on some biological characteristics of the parasitoid Bracon hebetor Say (Hymenoptera: Braconidae) were examined. Different concentrations of IAA (5, 50, 100, 500 and 1000 mg L-1) were added to the synthetic diet of host larvae. The developmental period, adult longevity, fecundity, and sex ratio of parasitoids reared on these hosts were evaluated with respect to IAA concentrations. IAA treatment shortened the developmental period of female wasps at almost all concentrations except for 50 mg L-1. The developmental period of males showed fluctuations among IAA-treated groups with a significant decline at 5 and 500 mg L-1 and a considerable increase at 50 mg L-1 with respect to the control group. IAAshowed a significant negative effect on the fecundity of B. hebetor. However, the sex ratio of the parasitoid did not differ among the IAA-treated and untreated groups. B. hebetor females reared on IAA-treated hosts had lower longevity at 50, 100, 500 and 1000 mg L-1 than the females reared on untreated hosts. For males, a significant decrease in longevity was also determined at all concentrations compared to the controls.
