Insecticide resistance in cabbage aphidBrevicoryne brassicae

Journal of Entomological Research, 2016
The lc50 values of imidacloprid 17.80% Sl, thiamethoxam 25% WG, acetamiprid 20% SP and dimethoate 30% EC were more in case of aphids collected from farmer's field (insecticide treated) than untreated field. The resistance factor (rF) of acetamiprid, imidacloprid, thiamethoxam and dimethoate was 85.06, 137.80, 13.50, and 44.17 folds, respectively.
