In a Central Michigan wetland setting, air drawn through a DEET-impregnated screen using an electric fan and projected toward a human subject significantly reduced mosquito orientation by 74%, landing by 75%, and probing by 70%, relative to no applied wind or DEET. The DEET vapor effect was significant as revealed by a statistically significant wind/DEET interaction. The wind speed at the downwind human subject was 0.6 m/s and the DEET vapor concentration was estimated at 2 microg/liter air. We suggest a combination of directed wind and volatile repellent might be developed as a mosquito deterrent strategy for the backyard setting.
在密歇根州中部的湿地环境中，使用电风扇使空气通过浸有避蚊胺的纱窗并吹向人体受试者，与不施加风或避蚊胺的情况相比，显著降低了蚊子的定向能力74%、着陆率75%和刺叮率70%。风/避蚊胺的交互作用具有统计学意义，表明避蚊胺蒸汽效应显著。下风向人体受试者处的风速为0.6米/秒，避蚊胺蒸汽浓度估计为2微克/升空气。我们建议，定向风与挥发性驱避剂相结合可作为一种在后院环境中驱蚊的策略加以开发。
