abstract
The working behavior of different Apis spp. while foraging on Indian mustard (B. juncea) variety RH-0749 was studied.The maximum nectar foraging was recorded in A. dorsata (37.25%) followed by A. florea (36.08%) bees. The maximum proportion of pollen gatherers were recorded in case of A. dorsata (26.00%) followed by A. mellifera (25.44%). Foraging for both nectar and pollen was the maximum in case of A. cerana indica (48.50%) followed by A. florea (43.50%), A. mellifera (42.94%) and A. dorsata (36.75%). The maximum percentage of nectar and pollen foraging by Apis spp. at different day hours was recorded at 1200-1400 h (47.75%) and 0800-1000 h (44.86%) respectively. The maximum proportion of top workers were in A. dorsata (100%) followed by A. cerana indica (90.25%), A. mellifera (82.94%) and A. florea (59.50%).
