Key words: Adjustable bee trapping devise, bees in Sal forest.
Sampling bees in forested areas from floral assemblages at different heights above ground possess serious problems to bee researchers. Active netting is not possible at that height. Passive trapping using food baits and water, although more promising, yield low catch-rates due to their restrictive placement. A unique adjustable contraption, an adaptation and modification of existing designs, has been devised to trap bees by placing the same in the flight-path of the bees. Four month long sampling from deciduous forests of lateritic tracts of West Midnapore district of West Bengal, India, shows significant success in trapping pollinator bees at canopy height using this device, with minimum effort and trouble on part of the sampler, thereby increasing sampling efficiency and reducing sampler bias.
