|Abstract||The toxicity of bifenthrin, cyfluthrin, lambda-cyhalothrin, cypermethrin, deltamethrin, esfenvalerate, fluvalinate, phosalone and pirimicarb were assessed in the laboratory on the parasitic hymenopteran Aphidius rhopalosiphi. A strong toxic effect was found with every tested product when adult parasitoids were exposed to freshly applied residues on both glass plates and maize leaves for 24 hours. Only two products, fluvalinate and esfenvalerate, did not kill all the insects. No differences were observed between mortalities on glass plates and leaves. Applied on aphids mummies, cyfluthrin and deltamethrin slightly reduced the emergence of young parasitoids, but not their reproductive performance. The other tested products had no effects on adult emergence. On the basis of these results, the insecticides are of comparable toxicity to A. rhopalosiphi in the laboratory.|
