诱蚊诱卵器置于某多层住宅区不同方位的监测结果
Monitoring results of mosquito-ovitraps placed in different orientations in multi-storey residential areas
摘要
Abstract
[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(χ2=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(χ2=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(χ2=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 building(31.70%),and the difference in MOI was statistically significant(χ2=5.118,P=0.024).[Conclusion]The study of MOI in different orientations in a multi-storey residential area is a preliminary exploration based on field work,and the results show that there is a difference in MOIs in different orientations during the peak breeding period of mosquitoes.Further indicators such as temperature,humidity and wind speed in different orientations can be collected to explore the influencing factors of MOIs.关键词
