They play an important role in protecting plant diversity and sustaining the balance of ecosystem, etc. This paper introduced the species, distribution, and functions in the nutrition supply and colonization resistance against invasion of exotic microbes of symbionts in honeybees and bumblebees. It also analyzed the problems to be solved, discussed the hotspots of future research, and provided references for improving bees′ adaptability to environment, and controlling its diseases and insect pests.
