Increasing pollination efficiency is a low input but a sound effect on output without much expense to the environment. Honeybees are naturally important pollinators of plants throughout their natural range. This book includes the role of these different honeybee species on rapeseed production. Similarly, it also contains distribution of insect pollinators as near and far from natural habitats and foraging behaviours of different honeybee species. Finally, the farmer’s perception about the effect of chemical pesticide on insect pollinators is also contain in this book.
