摘要
目的分析河北省成蚊生态学监测数据,了解蚊种构成、分布、密度和季节消长等,为媒介蚊虫和蚊媒传染病防制提供依据。方法2011-2022年采用诱蚊灯法监测蚊虫,共收集河北省17个市、县级监测点的监测数据,利用R 4.2.2软件,采用χ^(2)检验、Kruskal-Wallis H检验和Friedman检验等进行统计分析。结果2011-2022年平均蚊密度为1.24只(/灯·h),淡色库蚊、三带喙库蚊、白纹伊蚊、中华按蚊和其他蚊种分别占96.62%、1.72%、1.27%、0.31%和0.08%,各年平均蚊密度呈波浪式缓慢下降趋势,不同年份间蚊密度差异有统计学意义(H=36.155,P<0.001),2020-2022年白纹伊蚊密度持续上升。牲畜棚平均蚊密度最高,达1.55只(/灯·h),其次是农户,为1.39只(/灯·h),不同生境间平均蚊密度差异有统计学意义(Q=23.529,P<0.001)。各生境优势蚊种均为淡色库蚊,三带喙库蚊、中华按蚊在牲畜棚中的密度远高于其他生境,白纹伊蚊在5种生境的密度相近。蚊虫季节消长呈单峰曲线,密度高峰期为6-9月,8月达到峰值,平均蚊密度为2.38只(/灯·h),不同月份蚊种密度差异有统计学意义(H=15.143,P=0.034)。不同生境蚊密度在7-8月达到峰值,不同月份不同生境蚊密度差异有统计学意义(H=36.653,P<0.001)。结论河北省6-9月应重点加强牲畜棚和农户的蚊虫防制,农村地区还应重视三带喙库蚊、中华按蚊的防制,城市和农村应持续关注白纹伊蚊监测结果并适时采取防制措施。
Objective To analyze adult mosquito ecological surveillance data for an understanding of the species composition,distribution,density,and seasonal fluctuation of mosquitoes in Hebei Province,China,so as to provide a basis for the prevention and control of mosquitoes and mosquito-borne infectious diseases.Methods Mosquitoes were monitored using the lamp trap method from 2011 to 2022.The surveillance data of 17 surveillance sites at city and county levels were collected in Hebei,and analyzed using the Chi-square test,Kruskal-Wallis H test and Friedman test with R 4.2.2 software.Results From 2011 to 2022,the average mosquito density was 1.24 mosquitoes/lamp·h.Culex pipiens pallens,Cx.tritaeniorhynchus,Aedes albopictus,Anopheles sinensis,and other mosquito species accounted for 96.62%,1.72%,1.27%,0.31%,and 0.08%,respectively.The annual average mosquito density decreased slowly in a fluctuating way,with a statistical difference in mosquito density between different years(H=36.155,P<0.001).The density of Ae.albopictus kept increasing from 2020 to 2022.The highest average density was 1.55 mosquitoes/lamp·h in livestock sheds,followed by 1.39 mosquitoes/lamp·h in rural houses,with a statistical difference in the average mosquito density between different habitats(Q=23.529,P<0.001).The dominant species was Cx.pipiens pallens in all habitats.The densities of Cx.tritaeniorhynchus and An.sinensis were much higher in livestock sheds than in other habitats.Ae.albopictus showed close densities in five habitats.The seasonal fluctuation of mosquitoes showed a single-peak curve,with high densities occurring from June to September,peaking in August,with the average mosquito density being 2.38 mosquitoes/lamp·h.There was a statistical difference in mosquito density between different months(H=15.143,P=0.034).The mosquito densities in different habitats peaked during July to August.The difference in the mosquito densities in different habitats between different months was statistically significant(H=36.653,P<0.001).Conclusions In
