Abstract
An experiment was carried out to study the safety of some new insecticides namely chlorantraniliprole 18.5 SC, flubendiamide 20 WG, buprofezin 25 SC, lambda cyhalothrin 5 EC, thiamethoxam 25 WG, dinotefuran 20 SG, thiacloprid 21.7 SC and azadirachtin 5 % w/w on egg, larval and pupal stage of Trichogramma japonicum parasitizing UV irradiated and unirradiated Corcyra cephalonica eggs by evaluation of percent reduction in adult emergence of when treated after 1st, 3rd and 5th day of parasitisation which is during egg, larval and pupal stage of Trichogramma respectively. Lambda cyhalothrin adversely affected the emergence of T. japonicum during all the life stages of T. japonicum. However azadirachtin, buprofezin, chlorantraniliprole and flubendiamide least affected the per cent reduction in adult emergence than other insecticides. Thiamethoxam was found selective towards different life stages of T. Japonicum.
