在风洞中，将致倦库蚊雌性蚊子暴露于亚致死量的v-丙烯菊酯、速灭菊酯和胡椒基丁醚，作为超低体积(ULV)的液滴。在治疗前、治疗中和治疗后，对蚊子进行视频记录，然后使用复合显微镜测定蚊子身上的飞沫数量和大小。在喷洒过程中，蚊子飞行的时间更长，与其身上的飞沫数量呈正相关。在暴露于丙戊菊酯的蚊子中，以增加飞行速度和持续时间的形式表现出的兴奋是立即的，而暴露于速灭菊酯的蚊子并不会增加它们接触ULV飞沫的机会。讨论了蚊子上飞沫的位置、飞沫体积的影响以及随后的死亡率。
Female Culex quinquefasciatus Say (Diptera: Culicidae) mosquitoes were exposed to sublethal amounts of v-allethrin, sumithrin, and piperonyl butoxide applied as ultralow volume (ULV) droplets in a wind tunnel. Mosquitoes were video recorded before, during, and after treatment, and the number and size of droplets on their bodies were later determined using a compound microscope. A positive correlation was found between mosquitoes that spent more time flying during the time of spraying and number of droplets on their bodies. Excitation, in the form of increased speed and duration of flight, was immediate in mosquitoes exposed to prallethrin, whereas exposure to sumithrin did not increase their exposure to the ULV droplets. The location of droplets on mosquitoes, the effects of droplet volume, and subsequent mortality are discussed.
