Abstract: ABSTRACT The present investigations entitled, “Studies on bumble bee (Bombus haemorrhoidalis Smith) pollination in Capsicum annuum L. under protected cultivation” (variety- Solan Bharpur) were carried out in the Apiculture laboratory of the Department of Entomology and at the experimental farm of Department of Seed Science and Technology (Khaltu), Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). The B. haemorrhoidalis queens were collected while foraging on Adhatoda vasica, Brassica juncea, Hypericum oblongifolium, Papaver rhoeas, Scutellaria linearis, Cydonia oblonga and Antirrhinum majus from February to April. Bumble bee colonies were reared under laboratory conditions by maintaining 27±1°C temperature and 65-70% relative humidity and fed with 50% sucrose solution and fresh/stored pollen collected from honeybee colonies. Success rate of colony development under laboratory was more in queens collected during April (60%) as compared to queens collected during March (31.25%) and February (16.67%). Similarly, the per cent successful establishment in the field was recorded more in queens collected during April (40%) in comparison to queens collected during March (18.75%). Laboratory reared bumble bee colonies and A. mellifera were used for pollination in bell pepper grown under protected cultivations. A. mellifera foragers got disoriented in polyhouse and gathered on the side wall instead of foraging on bell pepper flowers. The bumble bee pollination resulted in increase in number of fruits per plant (3.77%), fruit weight (g) (24.60%), fruit length (cm) (13.51%), fruit breadth (cm) (21.52%), healthy fruits (23.84%), seed number (113.64%), 1000 seed weight (g) (5.44%) and fruit yield per m2 (kg) (89.42%) in bell pepper over control suggesting that bumble bee pollination is effective in improving bell pepper fruit yield and quality.
