摘　　要：目的使用挂笼法评价无人机喷雾在居民区内地面不同位置的灭蚊效果,为现场喷雾灭蚊效果评价提供参考方法,为蚊虫和蚊媒传染病的防控提供基础。方法选取浙江省浦江县2个居民区(村庄)进行无人机喷雾灭蚊,在灭蚊喷洒开始前将装有白纹伊蚊的蚊饲养笼挂在地面的露天环境、稀疏树枝上、茂密树下等3种不同环境中,观察不同位置蚊笼中白纹伊蚊的死亡情况,并与对照笼结果比较,分别计算不同位置、不同时间蚊笼中蚊虫的死亡率,用以评价无人机喷雾对地面不同位置蚊虫的杀灭效果。采用χ^(2)检验或Fisher确切概率法比较不同组间死亡率。结果无人机喷雾后,挂笼中的白纹伊蚊敏感品系在露天环境中2.5 h内全部死亡;稀疏树枝上2.2~2.5 h死亡率为90.21%,4.5~5.0 h死亡率为94.89%,10.0 h死亡率达到最高,为99.15%;茂密树下2.2~2.5 h死亡率为82.74%,4.5~5.0 h死亡率为91.15%,10.0 h死亡率达到最高值(96.02%);露天环境、稀疏树枝上、茂密树下3种环境中蚊虫最高死亡率依次降低,但差异无统计学意义(P=0.190)。露天环境中的白纹伊蚊本地野外种群2.2~2.5 h内死亡率达到77.63%,4.5~5.0 h死亡率为94.74%。结论挂笼法是一种评价无人机喷雾灭蚊效果的有效方法。无人机喷雾对露天环境、稀疏树枝上、茂密树下挂笼中的白纹伊蚊均有良好的杀灭效果,无人机喷雾可以作为一种有效的城乡居民区环境灭杀成蚊的方式。Objective To evaluate the killing effect of unmanned aerial vehicle(UAV)spraying at different locations in residential areas against mosquitoes by the hanging cage method,so as to provide a reference method for the evaluation of mosquito control effect by spraying on site,and to provide a basis for the prevention and control of mosquitoes and mosquito-borne diseases.Methods Two residential areas(villages)were selected in Pujiang County,Zhejiang Province,China.The mosquito cages for feeding containing Aedes albopictus were hanging in various scenes such as the open environment on the ground,sparse branches,and under dense trees,and all the locations were under the UAV spraying.The mortality rate of Ae.albopictus in mosquito cages at different locations at different time points was calculated and compared with that in the control cages by the Chi-square test and Fisher's exact test.Results After the UAV spraying,for the sensitive strains of Ae.albopictus,all were killed within 2.5 h in the open environment;on sparse branches,the mortality rate reached 90.21%at 2.2-2.5 h,94.89%at 4.5-5.0 h,and the highest(99.15%)at 10.0 h;under dense trees,the mortality rate reached 82.74%at 2.2-2.5 h,91.15%at 4.5-5.0 h,and the highest(96.02%)at 10.0 h;the highest mortality rates of mosquitoes in the three environments were in descending order,without significant differences(P=0.190).For the local populations of Ae.albopictus,the mortality rate reached 77.63%within 2.2-2.5 h and 94.74%at 4.5-5.0 h in the open environment.Conclusions The hanging cage method is an effective method to evaluate the killing effect of UAV spraying against mosquitoes.The UAV spraying shows a good killing effect on Ae.albopictus in cages in the open environment,on sparse branches,and under dense trees.The UAV spraying is an effective adult mosquito killing method in the urban residential environment.
