This study evaluated the efficacy of selected insecticides against thrips Scirtothrips dorsalis (Hood) on chilli. All the insecticides significantly reduced the infestation, with imidacloprid 17.8%SL (0.68 thrips/ 3 leaves/ plant) giving maximum control; it was followed by spinosad 45%SC (0.89). The most economical treatment was imidacloprid 17.8% SL giving yield of 134.58 q/ ha (with benefit cost ratio 1:9.04) followed by spinosad 45%SC giving yield of of 128.29 q/ ha (with benefit cost ratio 1:7.45).
