目的 通过统一、规范的监测方法，掌握广东省白纹伊蚊种群密度及季节消长情况，为伊蚊媒介传染病的预警预测提供科学依据。方法 2007－2017年，在广东省采用布雷图指数（BI）法、诱蚊诱卵器指数（MOI）和诱蚊灯法3种方法对白纹伊蚊密度进行监测。结果 BI法监测伊蚊幼蚊密度，共调查9 506 102户，BI均值为2.94；MOI法监测伊蚊成蚊密度，共布放有效诱蚊诱卵器1 428 078个，MOI均值为4.98；诱蚊灯法监测伊蚊成蚊密度，共布放有效诱蚊灯82 019盏，伊蚊平均密度为0.21只/（灯·夜）。经方差分析和Bonferroni两两比较，BI法在不同环境的监测结果差异有统计学意义（F=69.158，P<0.01），MOI和诱蚊灯法在不同环境的监测结果差异无统计学意义（F=1.642，P=0.174；F=1.973，P=0.081）。3种监测方法结果表明，夏、秋两季的伊蚊密度高于冬、春两季。结论 广东省全年均有白纹伊蚊，不同年份、不同季节种群密度不同，应根据具体情况采取针对性的措施对其进行防控。监测方法在不同环境中的敏感度不同，应根据监测环境选择。
Objective To understand the seasonal variation in the population density of Aedes albopictus in Guangdong province, China, based on a standard surveillance method, and to provide a scientific basis for the early warning and prediction for Aedes-borne diseases. Methods From 2007 to 2017, the population density of Ae. albopictus in Guangdong province was monitored by Breteau index (BI), mosquito ovi trap index (MOI), and the mosquito light trap method. Results The Ae. albopictus larvae density surveillance in 9 506 102 houses resulted in a mean BI value of 2.94. The adult Ae. albopictus density surveillance using 1 428 078 effective mosquito ovitraps resulted in a mean MOI value of 4.98. The adult Ae. albopictus density surveillance using 82 019 effective mosquito light traps resulted in an overall Ae. albopictus density of 0.21 mosquito/lamp·night. Between-group comparison made by analysis of variance and the Bonferroni method showed that there was a significant difference in BI surveillance results between different environments (F=69.158,P<0.01). However, there were no significant differences in MOI or mosquito light trap surveillance results between different environments (F=1.642, P=0.174; F=1.973, P=0.081). According to the surveillance results by the three methods, the population density of Ae. albopictus was higher in summer and autumn than in winter and spring. Conclusion Aedes albopictus exists all the time of a year in Guangdong province. The population density of Ae. albopictus varies with year, and season. Therefore, the prevention and control of Ae. albopictus should be performed on a case-by-case basis. The sensitivity of a surveillance method varies with environment, suggesting that the selection of surveillance methods should depend on the surveillance environment.
