Popis:	Bioassay was conducted with nine botanical extracts at various concentrations viz., azadirachtin 300ppm, 1500ppm, 3000ppm, 10000ppm, neem seed oil 1%, 2%, 3%, neem seed extract 5% and dashparniark 4% on Trichogrammatoidea bactrae Nagaraja (Hymenoptera: Trichogrammatidae) in completely randomized design. Assessment of these on % parasitization, reduction in parasitism and adult emergence of T. bactrae on Corcyra eggs was done. The results revealed that dashparniark (ten plant leaves extract) 4% was found safer with maximum parasitization (53.3%) and minimum reduction in parasitization (27.9%). Azadirachtin 10000ppm was found harmful resulting in reduced parasitization (12.6%) and adult emergence (32.6%); and maximum reduction in parasitism (82.9%) on Corcyra eggs was observed. Maximum % adult emergence was recorded when parasitized eggs were treated with neem seed oil 1% (64.3%).
