Field experiments were conducted to record the diversity of floral visitors/pollinators in Bitter gourd Kharif season, 2018, with three replications. The experimental plot was kept free from chemical sprays during the flowering period. Insects belonging to various orders like Hymenoptera, Lepidoptera, Diptera, Hemiptera and Coleoptera were found visiting the bitter gourd flowers. Major pollinators of bitter gourd have been identified by their foraging activity. Foraging behaviour of major pollinators were recorded during different hours of the day viz. 0600 to 1800h based on No. of individuals/5min/m2, Time spent by one individual (sec) on each flower, No. of flowers visited by one individual /5min and No. of individuals visited per flower/5min. Insects foraging on pollen and nectar from the flower were also recorded. From the above observations it was found that the bees forage on bitter gourd flowers very actively from 0600 to 1600 hours at a varying level.
