目的探讨伊蚊诱捕器监测指标与传统蚊媒监测指标之间的关系,并分析气候因素对伊蚊密度的影响。方法利用伊蚊诱捕器在广州市海珠区某社区对蚊媒密度进行为期11个月的常规监测。对伊蚊诱捕器监测指标与传统指标进行相关回归分析,并对气候因素(温度、湿度)与伊蚊密度进行回归分析。结果伊蚊诱捕器监测指标诱蚊指数、诱卵指数、诱蚊诱卵指数与传统指标(布雷图指数)之间具有相关性(r=0.758,P=0.007;r=0.667,P=0.025;r=0.758,P=0.007),并得回归方程Y=1.045+0.677a-0.590b(Y:布雷图指数,a:诱蚊指数,b:诱卵指数);对气候因素与伊蚊密度进行回归分析,得到:Y=-18.358+1.297a(Y:白纹伊蚊总数,a:温度);Y=-702.837+47.035a(Y:蚊卵总数,a:温度)。结论伊蚊诱捕器监测指标与传统指标之间具有相关性,伊蚊诱捕器监测法的可信性较强,同时,气候因素是影响伊蚊密度的重要因素。
Objective To explore the relationship between the monitoring index of mosquito traps and the traditional mosquito monitoring indicators and to analyze the influence of climate factors on the density of mosquito. Methods Aedes mosquito traps were used to monitor mosquito density in a community in Haizhu District of Guangzhou for 11 months. The regression analysis was conducted between the monitoring indicators of Aedes albopictus trap and the traditional indicators and the regression analysis of the climatic factors (temperature, humidity) and Aedes aegypti density. Results The indices of mosquito index, oviposition index, mosquito - oviposition index and the traditional index (Brett Index) were correlated with the indices of mosquito trapping (r = 0.758, P = 0.007; r = 0.758, P = 0.007), and the regression equation Y = 1.045 + 0.677a-0.590b (Y: Brett index, a: mosquito index, b: Regression analysis yielded: Y = -18.358 + 1.297a (Y: the total number of Aedes albopictus, a: temperature); Y = -702.837 + 47.035a (Y: the total mosquito eggs, a: temperature). Conclusions There is a correlation between the monitoring index of the mosquito traps and the traditional indexes. The reliability of the monitoring method of the mosquito traps is strong. Meanwhile, the climatic factors are the important factors that affect the density of the mosquito.
