Abstract: Crops pollination deficiency is becoming one of the serious problems in agricultural production in China. Honeybee is naturally an efficient pollinator, and was breed on a large scale in China, thus should be applied in solving the crop pollination deficient problem. When using the honeybee to pollinate crops, the attractiveness of crops to honeybee is different due to the difference in nectar and pollen secretion. While the requirement for food between the large and small colony is different, leading to the difference in foraging preference for pollen or nectar. Those differences ultimately affect the efficiency in using honeybee pollination for crops. To explore the appropriate colony scale for different nectar and pollen secretion crops and efficiently utilizing honeybee for crops pollination, nectar and pollen secretion of crops were classified to several types. Then the biological characteristics of bee colony related to pollination such as colony internal requirements and foraging preference were detail discussed. Lastly, a conclusion of utilizing large scale bee colony pollinating for more nectar secretion crops type, and small scale colony around 3-4 comps pollinating for more pollen less nectar secretion crops type were drew. Such a conclusion was theoretic important and could be used for directing honeybee pollination for crops.
