Toxicity of Flubendiamide 20 Wg against Egg Parasitoid, Trichogramma chilonis (Ishii). (Hymenoptera: Trichogrammatidae) under Laboratory Conditions

Abstract

The impact of flubendiamide 20 WG, on egg parasitoid was studied in laboratory experiments to assess its safety Trichogramma chilonis (Ishii). Among the insecticides tested, the highest per cent parasitization (84.16 %) was recorded in flubendiamide 20 WG at 50 g a.i. ha^-1, followed by 60 and 70 g a.i. ha^-1 (80.20 and 80.04 %). Maximum adult emergence per cent was 89.70 at 50 g a.i. ha^-1 followed by 82.91 and 87.30 per cent for flubendiamide 20 WG at 60 and 70 g a.i. ha^-1, respectively at 72 h after the treatment and flubendiamide 20 WG at all the doses tested caused no adverse effect when compared to other insecticides.
