摘　　要：【目的】分析云南省勐腊县流行性乙型脑炎(简称“乙脑”)相关蚊媒流行特征及变化趋势,为科学防控乙脑提供依据。【方法】收集2016—2020年云南省勐腊县乙脑监测点的蚊媒监测数据,对其进行描述、比较和分析。【结果】2016—2020年云南省勐腊县乙脑蚊媒监测点累计捕获蚊虫1689只。其中2020年捕获最多,占36.3%;2017年最少,占13.3%。三带喙库蚊密度最高,为3.04只/(灯·d),中华按蚊密度最低,为1.03只/(灯·d),相同年份蚊种分布差异有统计学意义(P<0.01)。猪舍蚊密度为12.93只/(灯·d),住人房屋(简称“人房”)蚊密度为4.67只/(灯·d),不同蚊种在猪舍的蚊密度均高于人房,中华按蚊的场所分布差异无统计学意义(P=0.67),三带喙库蚊、致倦库蚊及其他蚊种的场所分布差异均有统计学意义(P<0.01)。5月为蚊虫活动高峰期,7月出现蚊媒活动小高峰。5—10月总体上呈现逐月下降趋势,不同蚊种的活动高峰期出现月份存在一定差异,三带喙库蚊活动高峰期在5月。【结论】勐腊县乙脑疫情防控形势依然严峻,建议在蚊虫活动高峰季加强防蚊灭蚊工作,积极开展爱国卫生运动,并做好宣传教育。同时,应加强辖区适龄儿童的乙脑疫苗接种查验工作,并做好医务人员的培训。[Objective]To analyze the epidemic characteristics and trend of mosquito vectors related to Japanese encephalitis(JE)in Mengla County,and to provide scientific evidence for JE prevention and control.[Methods]The JE related mosquito vector monitoring data in Mengla County from 2016 to 2020 were collected and subjected to further statistical analysis.[Results]A total of 1689 mosquitoes were captured at the JE mosquito vector monitoring sites in Mengla County,36.3%of which were captured in 2020 and 13.3%in 2017.The density of Culex tritaeniorhynchus was the highest(3.04 per lamp per day),and that of Anopheles sinensis was the lowest(1.03 per lamp per day).The distribution of mosquito species showed significant difference in the same year.The mosquito density in pig house was 12.93 per lamp·day,and that in human house was 4.67 per lamp·day.The mosquito density of different mosquito species in pig house was higher than that in human house.There was no significant difference in the site distribution of Anopheles sinensis,but there were significant differences in the site distribution of Culex tritaeniorhynchus,Culex pipiens quinquefasciatus and other mosquito species.The mosquito density peaked in May(12.78 per lamp per day)and July(10.28 per lamp per day).The temporal distribution showed that the vector density decreased gradually from May to October,however,the species population structure also varied significantly,and the trends of each mosquito species also varied greatly.In Mengla,Culex tritaeniorhynchus peaked in May.[Conclusion]The JE epidemic situation in Mengla County is still severe.It is recommended to strengthen prevention and control in the peak season of mosquito activities,such as actively carrying out patriotic health campaigns,and effective public education.At the same time,we should also strengthen the JE vaccination for school-age children and the training of medical personnel.
