Abstract The floral biology, insect pollinators and their abundance, quality and quantity of nectar, foraging activity of honeybee species, stigmatic surface relation to fruit characters and impact of different modes of pollination on quantitative and qualitative parameters was studied in Cucumber var. US54 at US Agri seeds India Private Limited, Kakol, Bangalore, during 2005. Of seventeen species of insect pollinators that visited Cucumber flowers eight species belonged to order Hymenoptera, five species to Diptera, two species to Coleoptera and three species to Lepidoptera were found visiting during flowering period. Among Hymenopterans, honey bees constituted 47.00 per cent of the total insect pollinators visiting Cucumber. The quantity of nectar in Cucumber gradually increased with the advancement of time and reached maximum at 1200 hr in both staminate (2.06 μl) and pistillate (2.53 μl) flowers. The maximum foraging activity of Apis cerana indica, was observed at 1000 hr. The time spent for foraging on staminate flowers was more than on pistillate flowers. Under bee pollination fruit set, fruit weight, fruit volume, and fruit length was highest under open pollination mode which was on par with that of bee pollination mode. When frequency of visit of Apis cerana Cucumber flowers increases from 1 to 6 visits per flowers there was a significant increases in fruit set, fruit weight , fruit volume and number of filled seeds per fruit in Cucumber when the number of bee visits were six per flower. The receptivity of stigma was maximum at 0800 hr and receptivity was lost by 50.00 per cent at 14 hr.
