Abstract: China’s pear planting area and output take the first place in the world. Because of wide planting, there are certain intervals of pear fluorescence from south to north, so the apiaries need to move for pear pollination. By analyzing the factors, such as different planting structures, the effects of bee foraging frequency on the percentage and weight of pear pollen foraged by honeybees and the percentage of bees foraging pear pollen, we studied the influence of repeated bee foraging on bee foraging ability during pear pollination, and the effects of oilseed rape and other competing plants which had overlapped florescence with pear on honeybee pollination for pear. The results showed that the competing plants could decline the foraging initiatives of swarm, and their planting should be avoided near pear orchard. Repeated foraging could enhanc enhance the foraging initiatives and the pollination effect, so professional apiaries could play a role in pear pollination.
