蚊香已广泛应用于防蚊叮咬。为了观察烟密度对蚊香击倒淡色库蚊雌性成蚊作用的影响,作者在实验室内进行了一系列的观察。采用扫描电镜观察含丙烯菊酯有效成份dl,d-T80的蚊香烟颗粒,显示在蚊香燃点上空3cm和30cm处收集的烟颗粒直径分别为0.2μm以下和0.4～1.0cm。前者明显小于后者。其原因是烟颗粒在上升的过程中不断
Mosquito coils have been widely used in mosquito bites. In order to observe the effects of smoke density on the mosquito-repellent effect of female mosquitoes in mosquitoes of Culex pipiens pallens, the authors conducted a series of observations in the laboratory. Scanning electron microscopy was used to observe the mosquito cigarette particles containing the active components dl and d-T80 of allethrin. The diameters of the smoke particles collected at 3cm and 30cm above the ignition temperature of the mosquito were below 0.2μm and 0.4 ~ 1.0cm respectively. The former is significantly smaller than the latter. The reason is that the smoke particles are constantly rising
