Abstract

An aerial trail of odorous pheromone molecules extends downwind from a female pink bollworm moth that is receptive for mating. Males apparently sense the boundaries of the trail during their characteristic zigzag flights across it. Contrary to previous beliefs, the mechanism by which the males steer toward the odor source does not require a sensing of wind direction.

摘要

从一只接受交配的雌性粉斑螟蛾身上散发出来的气味信息素分子在空中形成一条轨迹，顺着风向飘下。雄蛾在穿越这条轨迹时，显然会根据自身特有的锯齿状飞行方式来感知轨迹的边界。与之前的观点相反，雄蛾朝着气味源方向飞行的机制并不需要感知风向。
