abstract
Three dosages of insecticides viz., Imdaclorpid (17.8SL) @ 0.17, 0.28, and 0.58ml/L; Dimethoate 30EC @ 1.0, 1.5 and 2.0ml/L; Thioclorpid (21.7SC) @ 0.1ml, 0.2ml and 0.4ml/L; Cypermethrin (25EC) @1.0,1.5, and 2.0ml/L; Chlorpyriphos (20EC) @ 1ml, 1.5ml and 2 ml/L of water were compared with the treated check (Diclorovas) @ 1ml/L of water with untreated control for their efficacy against mealy cabbage aphid and biosafety of their natural enemies were evaluated. The bioefficacy of Imdaclorpid (17.8SL) @ 0.28ml/liter of water exhibited best performance on the basis of reduction of cabbage aphid mortality (85.89%) with less mortality (71.56%) of predatory fauna and with 4.4 % parasitization of mealy cabbage aphids which was statistically similar to other insecticides caused less mortality of natural enemies can be considered as potential insecticides against cabbage aphid in Cole crop of Kashmir.
