This study examines the effect of different insecticides on the foraging activity of bees on sunflower (Helianthus annuus). The findings indicated that cypermethrin 10% EC and imidacloprid 17.8% SL sustained less bee visits up to two days. On third day, normal bee activity was restored in case of cypermethrin 10% EC and imidacloprid 17.8% SL treated plots. Fipronil 5% SC exhibited less bee visits only on the day of spraying. The reduction in the bee activity was observed for four days subsequent to application of indoxacarb 14.5% SC.
