In agricultural habitat 10 bumblebee species were recorded; of
which 68.62% bumblebees were dominated by five species. However, in
non-agricultural habitat 13 bumblebee species were recorded and
more than 50% bumblebees were dominated by four species.
Significant variations were observed in the species richness of
non-agricultural habitat but none in case of abundance at habitat
level. However, same was true in case of non-cropped area as
compared to cropped area in agricultural habitat which reflected
the importance of non-cropped area as a refuge area for the
development of bumblebee colonies which ultimately play a vital
role in the pollination of crops, increasing their quality and
quantity. Trifolium alexandrinum. Medicago sativa and Solanum
tuberosum were visited by all bumblebee species in the cropped
area. Forage species separated in to two conspicuous groups
depending upon their utilization by bumblebees as a short and long
tongued bumblebees. Long tongued bumblebees were only attracted to
Ranunculus sp., Raphanus raphanistrum, Centaurea cyanus, Prunella
vulgaris, Cana indica, Stachys spp., Cirsium sp., Trifolium
pretense, Delphinium brunonianum and Lonicera periclymenum.
