Abstract: In order to investigate the effect of climatic factor change on the populations of honeybee in Caoba area， we recorded the climatic factor change in July， August， September 2014 by meteorograph of Vantage Pro2 and compared the numbers of eggs， larvae， pupae， workers and food storage measured by standard frame every 5 days in the same time. The results showed that there were negative correlations between temperature and larvae （r=-0.29）， food storage （r=-0.17）， workers （r=-0.65）， while the relative humidity had a positive correlation with the colony factors in July. In August， temperature had positive correlation with pupae （r=0.08） and food storage （r=0.73， P<0.05）， and had negative correlation with larvae （r=-0.53）， workers （r=-0.61）; Relative humidity however was quite opposite， which had negative correlation with pupae （r=-0.06）， food storage （r=-0.74）， and had positive correlation with larvae （r=0.51）， worker( r=0.61）. Furthermore， in September， temperature had positive correlation with the factors of honeybee population with larvae （r=0.62， P<0.05）， pupae （r=0.47， P<0.05）， food storage （r=0.7， P<0.05）， workers （r=0.79， P<0.01）; On the contrary， relative humidity had negative correlation with these factors with pupae （r=-0.21）， food storage （r=-0.24）， worker （r=-0.06） except for larvae （r=0.15）. The climatic factor decided temperature and humidity of macro environment which had relationship with the development of honeybee population. In conclusion, the population dynamics of honeybee （Apis mellifera L.） in temperature regions showed a characteristic seasonal pattern.
