目的观察绿篱施药技术现场控制白纹伊蚊密度的效果,为蚊媒传染病的媒介控制提供技术储备。方法采用2.5%高效氯氟氰菊酯微胶囊进行绿篱滞留喷洒,利用诱蚊诱卵器和人诱停落法监测蚊虫密度,观察施药前后试验区和对照区白纹伊蚊的密度变化。结果人诱停落指数结果显示,施药后的第1~4周白纹伊蚊相对密度下降率分别为92.7%、83.7%、89.1%和61.4%;诱蚊诱卵器法结果显示:施药后第1~4周的诱卵器指数下降率分别为91.4%、88.9%、76.6%和85.7%。结论绿篱施药技术可有效地控制外环境白纹伊蚊密度,持续时间为3周左右,为伊蚊媒介可持续性的控制和管理提供技术储备。
Objective To observe the effect of applying the technology of green hedgerows to control the density of Aedes albopictus on the spot and provide technical reserve for the vector control of mosquito-borne infectious diseases. Methods 2.5% lambda-cyhalothrin microcapsules were used to spray green hedgerows. The density of mosquitoes was monitored by mosquito-ovitrap and person-induced-drop method. The density of Aedes albopictus before and after the test was observed. The results showed that the relative abstraction rates of Aedes albopictus were 92.7%, 83.7%, 89.1% and 61.4% respectively from the first week to the fourth week after application. The results of mosquito-induced oviposition The decreasing rates of the index of the oogicators from the first week to the fourth week were 91.4%, 88.9%, 76.6% and 85.7% respectively. Conclusion The application of green hedgerows technology can effectively control the density of Aedes albopictus in the outer environment for a duration of about three weeks, providing technical reserves for the control and management of Aedes mosquito sustainability.
