“飞蛾展示了动物界最引人注目的远程化学交流的例子”1。最近关于雄蛾如何找到远距离雌性飞蛾的理论通过两种不同的方向线索来引导：(1)空气中气味浓度的梯度，用于‘空中气味跟踪’；(2)风，用于‘气味调节风动’2-7。实验室证据支持后一种理论，并与早期的辐射理论8-11相矛盾，但如果不在野外记录雄蛾的飞行轨迹，同时记录气味羽流的轨迹，这个问题就无法得到解决。现在已经对吉普赛飞蛾和风传播的气泡进行了这一研究，证实了理论(2)，并表明侧风投射本身有助于飞蛾逐步接近气味来源，这是风传播气味的方式的一个意想不到的结果12。
“Moths display some of the most striking examples of long-distance chemical communication in the animal kingdom”1. Recent theories of how the male moths find a distant female have invoked steering by two different directional cues: (1) gradients of odour concentration in the air, used in ‘aerial odour-trail following’, and (2) the wind, used in ‘odour-modulated anemotaxis’2–7. Laboratory evidence has favoured the latter theory as well as contradicting the earlier radiation theories8–11, but the issue could not be settled without recording in the field the flight track of a male moth and, simultaneously, the track of the odour plume. This has now been done with gypsy moths and wind-borne bubbles, confirming theory (2) and showing in addition that cross-wind casting itself contributes to a moth's progressive approach to the odour source, an unexpected consequence of the way odours are dispersed by the wind12.
