Abstract: Objective The paper aims to analyze the correlation among the biting cycles,the population quantity and the meteorological factors,based on the population density,the biting indexes and the meteorological data during 24 h at Beiwan frontiers in July 2004.Methods Investigating the biting indexes,the population density and meteorological factors:temperature,humidity and sunlight once per 1 h at day and night.Utilizing the correlation analysis and multiple regression model of SPSS 12.0.Results The population quantity showed negative correlation to temperature and sunlight,but showed positive correlation to humidity.The biting indexes had negative correlation to temperature and sunlight,but had positive correlation to humidity and population quantity.According to enter and stepwise regression methods,temperature x₁,humidityx₂,sunlight x₃,and population density(x₄) as the independent variables,biting indexes as dependent variable,regression equation were established,(1)y=-96.260+3.220 x1+0.544 x2+0.344 x₄),Multiple r=0.944,(2)y=5.717+0.333 x₄,Multiple(r=0.934.Significant test indicated the correlation were all significant.Conclusion The population activity and biting activity of Aedes vexans were associated with meteorological factors.The biting cycles significant related to population quantity.
