Palynological studies of pollen loads were carried out to determine the pollen sources for bumble bees under mid-hill conditions of Himachal Pradesh during 2016. The pollen loads were collected from queens and workers of B. haemorrhoidalis captured with the help of an insect net and then were released. A total of 73 pollen loads were collected. Microscopic preparations were made and palynological analysis was carried out. The analysis showed the occurrence of 68 pollen types served as pollen sources for bumble bee from amongst the fruit trees, medicinal plants, ornamentals, vegetable crops, weeds and wild trees. Out of these, 21 pollen types which formed homogenous pollen loads were considered as principal forage plants namely Solanum melongena, S. lycopersicum, Capsicum annuum, Digitalis purpurea, Digitalis lanata, Oenothera biennis, Martynia annua, Hibiscus syriacus, Agapanthus umbellatus, Salvia moorcroftiana, Moluccella laevis, Cassia sophera, C. fistula, Clitoria ternatea, Actinidia deliciosa, Peltophorum ferrugineum, Lupinus hartwegii, Dahlia imperialis, D. pinnata, Zinnia elegans and Justicia adhatoda.
