Abstract
The present investigation was undertaken to
gather the information of honey bee pollinators for their foraging rate while
visiting the flower of different, Brassica species. The experiment was
done on Indian at Norman E. Borlaug Crop Research Centre in Govind Ballabh Pant
University of Agriculture and Technology, Pantnagar (Uttarakhand) during the
rabi season 2020-21 to investigate the foraging rate of Apis species on
different cultivar of oilseed Brassica. Number of flowers visited per
minute by a particular bee was counted with the help of a stop watch. During
the blooming stage of oilseed Brassica spp. The findings indicate that
among the selected crops, A. mellifera exhibited a higher flower
visitation rate per minute compared to other Apis species, with A.
dorsata displaying the lowest rate. Additionally, within the Brassica species,
the highest flower visitation rate per minute was recorded for B. napus var.
GSC-6. The majority of Apis species were observed foraging
more actively between 1000-1200 hours compared to 1400-1600 hours. This
behavior can be attributed to their specialized anatomical structures, foraging
tendencies, distinct morphological characteristics such as hair density, and
variations in the size of body parts and pollen presentation patterns on the
flowers.
