| 520 | __ | |aThe research work on Toxicity of some insecticides against Helicoverpa armigera (Hubner) in Tomato (Lycopersicon esculentum Mill.) was carried out in the laboratory and field during 2017-2018 and 2018-2019. The laboratory studieswere done in the Toxicology Laboratory, Department of Entomology. Field studies were conducted in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat. In resistance studies the field collected population of Nagaon, Darrang and Jorhat population of H. armigera showed low level of resistance to very high resistance to deltamethrin(Decis 2.8% EC) imidacloprid(Admire 70% WG), chlorantraniliprole(Coragen 18.5% SC) emamectin benzoate (Pocket 5% SG) and thiamethoxam(Eco-Champ 25% WG) upto fourth generation when reared on artificial diet. Resistance Ratio (RR), showed a range of 111.5-288.9 fold, 32.87-75.40 fold, 24.92-34.73 fold, 89.72-128.66 fold and 95-183.3 fold deltamethrin, imidacloprid, chlorantraniliprole, emamectin benzoate and thiamethoxam, re |
