Studies were conducted to determine diversity and abundance of pollinator fauna and their role on cucumber and Bittergourd production. The studies revealed that cucumber flowers attracted wide varieties of insects belonging to 4 orders, 12 families, 17 genera and 21 species. Of all these insects, honeybees were the most predominant and comprised more than 74 percent of the total flower visiting insects. There abundance was in the order Apis mellifera > A. cerana > A.dorsata > A. florea. The other important insects visiting cucumber flower were Xylocopa fenestrata, X. pubescens, Pithitus smaragdula, Halictus spp., Lasioglosium spp., Anthophora spp. and Andrena spp. which collected nectar and pollen and constituted important pollinators of cucurbits. Bittergourd flowers also attracted a large number of insects belonging to 4 orders, 10 families, 11 genera and 13 species. In case of bittergourd also, honeybees such as A. mellifera, A. dorsata and A. cerana were the most important pollinators which comprised more than 69% of the total flower visiting insects. Observation on diurnal pattern of flower visiting insects revealed that in case of cucumber, maximum population of A. mellifera was observed between am 09:00-10:00 when relative humidity was 76%, temperature 34°C, nectar sugar concentration 34.5%, solar radiation 36mW/cm2 and light intensity 40 lx. Another peak was observed in the evening between pm 16:00-17:00 when the relative humidity was 68 percent, temperature 36°C, nectar sugar concentration 36%, solar radiation 42mW/㎠ and light intensity 28 lx. A similar pattern was observed in Bittergourd also. Studies on seasonal pattern revealed that in cucumber and bittergourd flowers insect visitation increased during different weeks commencing from first week to 9th week and declined thereafter. The correlation coefficient between different flower visiting insects and weather parameters revealed that relative humidity, rainfall and minimum temperature had a negative influence on visitation pattern of bee species and other insects. However, maximum temperature had a pronounced effect on the popul ation of these bees which increased with the temperature. Mean evaporation had a positive effect on A. dorsata, A. cerana and Xylocopa species whereas negative effect on A. mellifera. The studies revealed that percentage fruit set varied in different treatments. In case of bee pollination, fruit set was significantly higher (84.14%) followed by hand pollination (76%) and open pollination (74.76%).
