在风洞中研究了二氧化碳（CO2）和人脚臭对致倦库蚊（Culex quinquefasciatus（Say））（双翅目：库蚊科）雌蚊趋宿主行为的激活、逆风定向和着陆的相互作用。更多的蚊子落在温暖的玻璃珠上，涂上脚臭，而不是干净的珠子;增加4%的二氧化碳羽流并没有影响蚊子着陆的比例。第二个实验使用三维视频跟踪来评估飞行性能。活化更迅速与CO2和CO2 +脚臭比与清洁空气或单独的脚臭。逆风飞行是最快的二氧化碳和清洁的空气，最慢的脚臭;二氧化碳+脚臭治疗重叠前三个治疗的意义。飞行标题倾向于与CO2和清洁的空气比与CO2 +脚气味或脚气味单独的正逆风。在这两个实验中，许多蚊子在干净的空气中逆风飞行。几乎没有证据表明，女性改变路线后，进入或退出的CO2羽流或在飞行过程中对脚臭的反应。
This study investigated the interaction between carbon dioxide (CO2) and human foot odour on activation, upwind orientation and landing of host-seeking female Culex quinquefasciatus (Say) (Diptera: Culicidae) in a wind tunnel. More mosquitoes landed on warmed glass beads coated with foot odour than on clean beads; adding a plume of 4% CO2 did not influence the proportion of mosquitoes landing. A second experiment used 3-dimensional video tracking to assess flight performance. Activation was more rapid with CO2 and with CO2 + foot odour than with clean air or with foot odour alone. Upwind flights were fastest with CO2 and with clean air, and slowest with foot odour; the CO2 + foot odour treatment overlapped the previous three treatments in significance. Flight headings tended more towards due upwind with CO2 and with clean air than with CO2 + foot odour or with foot odour alone. In both experiments, many mosquitoes flew upwind in clean air. There was little evidence of females changing course upon entering or exiting the CO2 plume or reacting to foot odour during flight.
