Impact of different insecticides on the activity of bees onsunflower

摘要

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.
