Males of the giant silk moth Antheraea polyphemus Cramer (Lepidoptera: Saturniidae) were video-recorded in a sustained-flight wind tunnel in a constant plume of sex pheromone. The plume was experimentally truncated, and the moths, on losing pheromone stimulus, rapidly changed their behaviour from up-tunnel zig-zag flight to lateral casting flight. The latency of this change was in the range 300-500 ms. Video and computer analysis of flight tracks indicates that these moths effect this switch by increasing their course angle to the wind while decreasing their air speed. Combined with previous physiological and biochemical data concerning pheromone processing within this species, this behavioural study supports the argument that the temporal limit for this behavioural response latency is determined at the level of genetically coded kinetic processes located within the peripheral sensory hairs.
在持续存在性信息素羽流的情况下，对大蚕蛾多音天蚕蛾（Antheraea polyphemus Cramer，鳞翅目：天蚕蛾科）的雄蛾在持续飞行风洞中进行了视频记录。实验性地截断了羽流，当雄蛾失去信息素刺激时，它们迅速将行为从向上的之字形飞行转变为侧向搜索飞行。这种变化的潜伏期在300 - 500毫秒范围内。对飞行轨迹的视频和计算机分析表明，这些雄蛾通过增大它们相对于风向的航向角同时降低空速来实现这种转变。结合此前关于该物种信息素处理的生理和生化数据，这项行为学研究支持了这样一种观点，即这种行为反应潜伏期的时间限制是在位于外周感觉毛内的基因编码动力学过程层面上确定的。
