Trichogramma (Hymenoptera; Trichogrammatidae) is a genus of parasitic wasps that are powerful biocontrol agents against a variety of insect pests. These biological control agents retain their importance due to their easy mass rearing, high searching ability and effectiveness against many crop insect pests. In this study the toxicological effect of seven insecticides viz Flubendiamide (Belt 480 SC)@ 500 ul/l, Pyriproxyfen (Priority 10.8 EC) @ 2000 µl/l, Chlorantraniliprole + Thiamethoxam (Voliam Flexi 300 SC) @ 800µl/l, Nitenpyram (Pyramid 10% AS) @ 2000 µl/l, Lufenuron (Match)@ 2000 µl/l, Chlorantraniliprole (Coragen 20% SC) @ 200 µl/l and Flonicamid (Ulala50% WG) @ 60 mg/l were evaluated on the viability of parasitized eggs, survival and parasitism efficacy of Trichogramma chilonis under controlled conditions at toxicology laboratory Entomological Research Institute Ayub Agriculture Research Institute, Faisalabad. The viability of eggs was evaluated by exposing egg cards to insecticides by dipping them in insecticide solution for 10 seconds while adult survival was investigated through dipped surface residue bioassay method. The results revealed that new chemistry insecticides viz., Flubendiamide, Flonicamid and Chlorantraniliprole were comparatively safer to egg parasitiod followed by Chlorantraniliprole while Nitenpyram and Pyriproxyfen was found toxic to Trichogramma. Flubendiamide, Chlorantraniliprole and Flonicamidwas proved comparatively less toxic against T. chilonis with emergence percentage while in the case of survival of T. chiloniswasps, the results revealed that Pyriproxyfen and Nitenpyram had less knockdown effect as compared to other insecticides while Lufenuron was most toxic at 4 h post treatment and at 24 h all the insecticides were equally toxic to the parasitoid at adult stage.
