摘　　要：【目的】了解诱蚊诱卵器置于多层住宅区不同方位监测结果是否有差别,为用诱蚊诱卵器在居民区开展白纹伊蚊常规和应急监测提供科学依据。【方法】于2023年7月6日—10月26日采用诱蚊诱卵器法在上海市奉贤区金汇镇某多层住宅区楼栋的东、南、西、北4个方位分别放置1个诱蚊诱卵器,72 h后回收并记录数据。采用χ^(2)检验比较两组独立样本的诱蚊诱卵指数(MOI),采用Kruskal-Wallis H检验比较多组独立样本的MOI。【结果】共监测16周,回收有效诱蚊诱卵器997个,阳性数211个,MOI为21.16%,诱蚊密度指数1.03只/个。其中9月和10月MOI较高,分别为24.22%和23.96%,这两月西面、南面和北面MOI均高于20.00%。7—10月东、西、南、北4个方位MOI分别为20.70%、22.20%、25.50%、16.20%,4个方位MOI差异无统计学意义(χ^(2)=6.647,P=0.084)。按月分层分析显示:8月多层住宅区南面MOI最高(31.30%),北面MOI最低(1.30%),东、西、南、北4个方位MOI差异有统计学意义(χ^(2)=25.986,P<0.001)。10月西面MOI最高(33.30%),东面MOI最低(6.30%),4个方位MOI差异有统计学意义(χ^(2)=12.007,P=0.007)。住宅区外沿楼栋南面从7月第1周—10月第4周MOI为19.20%,低于内部楼栋南面MOI(31.70%),MOI差异有统计学意义(χ^(2)=5.118,P=0.024)。【结论】对多层住宅区不同方位MOI的研究是基于现场工作的一个初步探索,结果显示,在蚊虫繁殖高峰期不同方位的MOI有差异。课题组后续将进一步收集不同方位的温度、湿度、风速等指标,以探究MOI的影响因素。[Objective]To find out whether there is any difference in the monitoring results of mosq-ovitraps placed in different orientations in multi-storey residential areas,so as to provide a scientific basis for routine and emergency monitoring of Aedes albopictus with mosq-ovitraps in residential areas.[Methods]From July 6th to October 26th 2023,one mosquito ovitrap was set up in each of the 4 orientations of east,south,west and north around the buildings in a multi-storey residential area in Jinhui Town,Fengxian District,Shanghai.Data was collected and recorded 72 hours after placement.The chi-square test was used to compare the mosquito ovitrap indices(MOIs)of two independent samples,and the Kruskal⁃Wallis H test was used to compare the MOIs of multiple independent samples.[Results]After 16 weeks of surveillance,997 mosquito ovitraps were recovered,of which 211 were positive,with the mosquito ovitrap index(MOI)of 21.16%and the Aedes albopictus density index of 1.03 mosquitoes·ovitrap-1.The MOIs were higher in September(24.22%)and October(23.96%),and the MOIs in the west,south and north within the two months were all above 20.00%.From July to October,the MOIs in the east,west,south and north were 20.70%,22.20%,25.50%and 16.20%,respectively,and the difference in MOIs among the 4 orientations was not statistically significant(χ^(2)=6.647,P=0.084).Stratified analysis by month showed that in August,the south side of the multi-storey residential areas had the highest MOI(31.30%),the north side had the lowest MOI(1.30%),and there was a statistically significant difference in MOI in the east,west,south and north(χ^(2)=25.986,P<0.001).In October,the MOI in the west was the highest(33.30%)and the MOI in the east was the lowest(6.30%),the difference in MOIs of the 4 orientations was statistically significant(χ^(2)=12.007,P=0.007).The MOIs in the south side of the building in the outskirts of the residential area from the 1st week in July to the 4th week in October was lower(19.20%)than that in the south side of the inner
