Abstract: Investigations were carried out at the Raninagar village of Chakdaha block in Nadia district of West Bengal during 2015-16 to study the foraging behavior of A. mellifera and A. dorsatain Onion (Allium cepa) crop. It was found that Foraging activity of A. mellifera started much earlier than A. dorsata and the peak activity was reached by 11am as against 1pm in the latter during February. A. dorsata visited more number of umbels but fewer numbers of florets per min than A. mellifera. Pollination had no impact on number of umbels produced/plant.
