Abstract: In order to analyze the annual population and potential impact factors of honeybee, Apis cerana cerana, in southern Yunnan, and to reveal the evolutionary relations between the press factor and colony that provide technological reference for conservation of bees, the number of larvae, pupae, adult and stores of honey and pollen by standard frame were measured every 15 days in Jan. to Dec. 2018 from 90 colonies, and then the correlation analysis was made. The results showed that the population of A. cerana cerana colony appeared intensely at the end of winter and the beginning of spring, annual populations was up and down. For the climate, rainfall was less in winter and spring in which the temperature fluctuated strongly, but summer and autumn was moist and hot. The temperature (a=0.977) was the major component for bee colony changes. The honey & pollen storage for colony had significant correlations with adults(r=0.580) and eggs/larvae(r=0.386), but had dramatically negative correlations with temperature(r=-0.248). The impact factors of A. cerana cerana populations involve the internal and external factors, in which the internal factors showed the season dynamics and external factors depended on colony management mode.
