摘　　要：目的了解贵州省登革热媒介伊蚊种群密度及分布情况,为登革热风险评估、预测预警及控制提供科学依据。方法2016-2020年每年的5-10月,采用诱蚊诱卵器法和人诱停落法对贵州省9个登革热媒介伊蚊监测点进行监测。利用Excel 2013软件汇总监测结果,SPSS 24.0软件对不同月份诱蚊诱卵指数(MOI)和叮咬指数进行方差分析。结果2016-2020年白纹伊蚊MOI为5.82~7.95,叮咬指数为11.69~17.01只(/人·h),MOI和叮咬指数高峰出现在8月,其中不同月份MOI差异有统计学意义(F=4.017,P=0.002)。结论白纹伊蚊在贵州省分布广泛且密度较高,登革热传播或流行风险较高;建议相关部门加强白纹伊蚊的监测及控制,减少蚊虫孳生,防止输入性登革热病例引起本地病例的发生。Objective To investigate the population density and distribution of Aedes mosquitoes in Guizhou province,China,and to provide a scientific basis for the risk assessment,prediction,early warning,and control of dengue fever.Methods From May to October of 2016 to 2020,mosq-ovitrap and human-baited landing methods were used for Aedes surveillance at 9 Aedes surveillance sites of Guizhou province.Data were pooled using Excel 2013.SPSS 24.0 was used to perform analysis of variance on the mosq-ovitrap index(MOI)and sting index of different months.Results From 2016 to 2020,the MOI of Ae.albopictus was 5.82-7.95,and the sting index of Ae.albopictus was 11.69-17.01 mosquitoes/person·h.The peaks of MOI and sting index were observed in August.There was a statistical difference in the MOI of different months(F=4.017,P=0.002).Conclusions Ae.albopictus is widely distributed and has a relatively high density in Guizhou province,suggesting a high risk of the occurrence or epidemic of dengue fever.Local health authorities should strengthen the surveillance and control of Ae.albopictus to reduce the breeding of mosquitoes and prevent local endemics of dengue caused by imported cases.
