Abstract
Bio-efficacy of seven
insecticides viz. Phosphamidon (0.03%) Dimethoate (0.03%) Carbayrl (0.03%),
Cypermethrin (0.01%) Chloropyriphos (0.05%), quinalphos (0.05%), Malathion
(0.05%), and untreated control (water) were evaluated against mustard, aphid, Lipaphis
crysimi Kalt and their effect on foraging bee Apis cerana during rabi
season 2017-18. Dimethoate was found to be the most effective in suppression of
aphid population upto 14 days after insecticidal treatment. Evaluation of the
effect of these insecticides on A. cerana population show that malathion
cypermethrin and quinalphos were safer to bees than carbaryl, dimethoate and phosphamidon
which did not reduce the bee population. Moreover, A. cerana spent
maximum time in flowers of cypermethin treated plots and minimum in carbaryl
treated plots. The highest seed yield was obtained with dimelthoate treated
plots, closely followed by phosphamidon and cypermethrin.
