摘　　要：应用无人机对白纹伊蚊成蚊及幼虫进行药物喷洒处置,观察施药前后白纹伊蚊成蚊及幼虫致死数量的变化,计算蚊虫杀灭率,评估采用无人机喷洒常用杀虫剂防制白纹伊蚊的效果。结果显示,与对照组相比,试验组无人机喷洒药物24 h成蚊死亡率均有显著差异。三组不同药物浓度试验组在施药6、12、24 h对成蚊杀灭率的差异无统计学意义。不同药物浓度组施药6、12、24 h不同时间点之间相比较,三组药物浓度对成蚊杀灭率差异无统计学意义。与对照组相比,试验组无人机喷洒药物24 h幼虫死亡率均有显著差异。三组不同药物浓度试验组在施药6、12、24 h对幼虫杀灭率的差异有统计学意义,其中1.5%浓度与6.0%浓度在3个时间点对幼虫的杀灭率均有差异,而1.5%与3.0%药物浓度、3.0%与6.0%药物浓度则无差异。施药6、12、24 h不同时间点之间相比较,三组药物浓度对幼虫杀灭率差异无统计学意义。结果表明,无人机喷洒拟除虫菊酯类药物可有效杀灭白纹伊蚊,这为登革热疫情暴发时针对环境复杂、人员喷洒无法深入作业的外环境进行蚊媒杀灭应急处置提供了新的有效技术手段,可有效提升现场蚊媒灭杀的效果和效率。Breeding environments of Aedes albopictus adults and larvae were sprayed of insecticide with unmanned aerial vehicle(UAV). The changes in the lethal number of adult and larval before and after application were observed, the killing rate of mosquitoes was calculated and the effectiveness of UAV spraying common insecticides against Aedes albopictus was evaluated. The results showed that compared with the control group, the mortality of adult mosquitoes 24 h after UAV spraying was significantly different in the three experimental groups. There was no significant difference in the killing rate of adult mosquitoes among the three experimental groups at different time points of 6 h, 12 h and 24 h. Compared with the control group, the mortality of larvae in the three experimental groups was significantly different at 24 h after UAV spraying. There were significant differences in the larval killing rate among the three experimental groups at 6 h, 12 h and 24 h, and the killing rates of 1.5% and 6.0% concentration were different at three time points, but there were no differences between 1.5% and 3.0% concentration and 3.0% and 6.0% concentration. There was no significant difference in the killing rate of larvae among the three groups at different time points of 6 h, 12 h and 24 h. Results show that the UAV spraying of pyrethroids can effectively kill Ae. albopictus, which provides a new technical means for the emergency treatment of mosquito vector killing in the external environment where the dengue fever outbreak is complicated and human spraying cannot go deep into the operation, and can effectively improve the implementation effect and efficiency of mosquito vector killing in the field.
