“…In other studies, Langhof et al (2002) reported that effects of agrochemicals against A. colemani showed high toxicities, and Candolfi et al (1999), in sub-lethal effect tests on Aphidius spp., also showed high sensitivities. In our study, similar results were found in A. gifuensis sensitivity to the various agrochemicals.…”

The contact and ingestion toxicities of selected agrochemicals applied at the standard field rate against adult females and pupae in host mummies of a native parasitoid Aphidius gifuensis were studied using several bioassays. Fresh residues of five insecticides (cartap, chlorfenapyr, emamectin benzoate, permethrin and imidacloprid) were found to be highly toxic against adult females as compared with the pupae in mummies. Evaluation of the residual effects of these five insecticides on cabbage foliage showed that cartap and imidacloprid were highly persistent. In the same assay, two IGRs (chlorfluazuron and lufenuron) and a fungicide (copper oxychloride) were harmless against adult females. When these agrochemicals were fed orally at the field rate, the mortality of adult females ranged from 13.3 to 46.7%. Ingestion of copper oxychloride had a slightly negative effect on parasitism.

“…Communities in areas adjacent to sprayed fields may also come into contact with pyrethroids in the form of spray drift. The survival of the aphid parasitoid Aphidius colemani in edge-of-field areas was impacted by spray drift from two applications of the lamba-cyhalothrin formulation Trafo ® at the recommended rate of 10 g a.i./ha (Langhof et al, 2003). Proportions of hoverfly (Syrphidae) eggs to aphids and percentages of aphid mummies increased with distance from edge-of-field, although these trends were not significant.…”

“…Proportions of hoverfly (Syrphidae) eggs to aphids and percentages of aphid mummies increased with distance from edge-of-field, although these trends were not significant. Authors concluded this was likely a result of the nonhomogenous distribution of lamba-cyhalothrin spray drift residues (Langhof et al, 2003). Subsequently, effects observed in edge-of-field areas probably will not be consistent between different fields, as the variables affecting the magnitude and distance of insecticide drift are highly site-specific.…”

“…Pesticides have been widely studied and have been shown to have a negative effect on natural enemy populations in many different studies (Chabert and Gandrey, 2005;Koss et al, 2005;Langhof et al, 2003;Tietjen and Cady, 2007). Both direct and indirect effects on the third trophic level have been highlighted.…”
