Abstract: A field experiment was conducted during 2021, at Gandhi Krishi Vigyan Kendra, UAS Bengaluru, to know the Effect of chemical insecticides used for management of mulberry thrips on silkworm rearing performance. The experiment was planned in Randomized Complete Block Design (RCBD) with 7 treatments T₁: Acephate 75 SP, T₂: Acetamiprid 20 SP, T₃: Dimethoate 30 EC, T₄: Fipronil 5 SC, T₅: Imidacloprid 17.8 SC, T₆: Dichlorvos 76 EC (std check) `and T₇: Control (water spray). It was recorded that Fipronil 5 SC @ 2 ml/l and Imidacloprid 17.8 SC @ 0.3 ml/l were found safer to silkworms 15 DAS and exhibited better rearing and reeling parameters. On contrary though Acetamiprid 20 SP @ 0.2 g/l and Acephate 75 SP @ 1 g/l were effective against thrips but had negative impact on silkworm rearing.
