Abstract

Field trials were conducted during Rabi 2008–09 at Marathwada Agricultural University, Parbhani. Honey bees started visiting the crop at 8.00 h, population was high during 13.00–16.00 h, declined slowly during 16.00–18.00h. In case of open pollination, intensity of Apis dorsata significantly reached at its peak between 12–14 h. In case of Bee-Q sprayed plots in general the intensity of all wild bees was increased as compared to open pollination. The intensity of A. dorsata was more between 12–14 h (2.66 bees/m2/min) and intensity was significantly higher on Bee-Q sprayed plots as compared to open pollination. In caged condition in all the treatments, the peak intensity of Apis florea was recorded during 10–12 h. In case of Bee-Q + SSS sprayed plots, the intensity of A. dorsata was more during 12–14 h (2.75 bees/m2/min). In the SSS sprayed plots, the intensity of A. dorsata was more during 1214 h.
