Abstract: Apple is the most important cultivation fruits in China. However, the lower average yield per unit area, a small proportion of optimal fruits and poor fruit quality have seriously restricted our competitiveness in the international market at present. Although, artificial pollination can improve the yield of apple, the cost is increasing. Alternatively, pollinators play an irreplaceable role in boosting the yield, particularly the ratio of optimal fruits, but their numbers in nature are gross shortage for recent years. Consequently it is impossible for meeting the demand of large scale development of apple industry. It is an important approach to ensure the sustainable development of apple industry through popularizing honeybees or mason bees for apple pollination and further researching on the artificial domesticating soil- nesting bees and leaf cutting bees as apple pollinators. Meanwhile, one must consider the arrangement of main and pollenizer varieties in an orchard. The author reviewed on floral traits, pollination patterns, pollinating insects as well as the influencing factors of pollination effect for apple. Based on what mentioned above, the author gave several suggestions for future studying on apple pollination. It was hoped that these information was benefit for improving apple production and fruit quality.
