Field study was conducted with ecofriendly insecticides on their effects on the foraging activity and time spent of bee pollinators in sunflower during 2016-17 and 2017-18 at the University of Agricultural Sciences, Bengaluru. Significantly less number of bees were observed with mahua oil one day after spray- 2.15 (Apis dorsata), 1.33 (A. cerana), 1.72 (A. florea) and 1.24 (Tetragonula iridipennis). BIPM (biointensive integrated pest management) and spinosad treatments led to maximum number of bees at 4 and 7 days after spray. The least mean time spent was observed with mahua oil treatment, whereas, BIPM and spinosad led to maximum mean time spent for all the bee pollinators. It is concluded that mahua oil has repellent activity on the bee pollinators.
