Females of Culex quinquefasciatus Say and Culex tarsalis Coquillet (Diptera: Culicidae) in the host-seeking stage were released and video recorded in three dimensions in a large field wind tunnel as they flew to four kinds of CO2-baited mosquito traps. The trapping efficiency (number of mosquitoes approaching compared to the number caught) was determined for each trap type. The Encephalitis Virus Surveillance (EVS), Mosquito Magnet Freedom (MMF) and Mosquito Magnet Liberty (MML) traps captured only 13-16% of approaching Cx. quinquefasciatus females, whereas the Mosquito Magnet-X (MMX) trap captured 58%. Similar results were obtained for Cx. tarsalis. Orientation behaviour and flight parameters of mosquitoes approaching the four traps were compared. Mosquitoes spent the most time orienting to the EVS trap. Flight speed decreased as mosquitoes entered the vicinity of each trap and a large portion of their time was spent within 30 cm downwind of the traps. Flights became highly tortuous downwind of the poorly performing traps and just upwind of the MMX trap. Differences between traps and possible explanations for the superior performance of the MMX trap are considered.
在大型野外风洞中，将处于寻找宿主阶段的致倦库蚊（Culex quinquefasciatus Say）和尖音库蚊（Culex tarsalis Coquillet）（双翅目：蚊科）雌性蚊子放飞，并在其飞向四种二氧化碳诱饵诱蚊器时进行三维视频记录。测定了每种诱蚊器的诱捕效率（接近的蚊子数量与捕获的蚊子数量之比）。脑炎病毒监测（EVS）诱蚊器、灭蚊磁体自由型（MMF）诱蚊器和灭蚊磁体自由型（MML）诱蚊器仅捕获了接近的致倦库蚊雌性蚊子的13%-16%，而灭蚊磁体-X（MMX）诱蚊器捕获了58%。尖音库蚊也得到了类似的结果。比较了接近这四种诱蚊器的蚊子的定向行为和飞行参数。蚊子花在定向到EVS诱蚊器上的时间最多。当蚊子进入每个诱蚊器附近时飞行速度降低，并且它们的大部分时间都花在诱蚊器顺风30厘米范围内。在性能较差的诱蚊器的顺风方向和MMX诱蚊器的逆风方向，飞行变得高度曲折。考虑了诱蚊器之间的差异以及MMX诱蚊器性能优越的可能原因。
