有性繁殖的一个重要部分通常涉及识别合适的交配伙伴。许多种类的雄蛾利用性信息素的气味来跟踪和定位同种雌蛾。然而，在雄性开始飞行之前，有必要通过颤抖主要飞行肌肉来热身，以达到适合维持飞行的胸部温度。在这里，我们展示了暴露在诱人的信息素混合物中的玉米蛾雄蛾(在某些情况下只接触主要信息素成分)比接触其他不完全或不吸引人的混合物的蛾更早开始颤抖，并在较低的胸腔温度下起飞。这导致了更少的颤抖时间和更快的加热速度。这些实验得出了两个有趣的结果。首先，产生热量的速度可以通过不同的嗅觉线索来调节。其次，检测到信息素混合物的雄性比暴露在其他刺激下的雄性在更低的胸部温度下起飞。这些雄鸟的起飞温度低于飞行肌肉产生最佳动力的温度，因此在快速起飞和次优飞行性能之间产生了权衡。我们的结果揭示了自由飞蛾的体温调节行为，这些行为与争夺雌蛾的竞争有关，并表明了快速飞行启动和次优飞行性能之间的生态权衡。
An essential part of sexual reproduction typically involves the identification of an appropriate mating partner. Males of many moth species utilize the scent of sex pheromones to track and locate conspecific females. However, before males engage in flight, warm-up by shivering of the major flight muscles is necessary to reach a thoracic temperature suitable to sustain flight. Here we show that Helicoverpa zea males exposed to an attractive pheromone blend (and in some instances to the primary pheromone component alone) started shivering earlier and took off at a lower thoracic temperature than moths subjected to other incomplete or unattractive blends. This resulted in less time spent shivering and faster heating rates. Two interesting results emerge from these experiments. First, the rate of heat generation can be modulated by different olfactory cues. Second, males detecting the pheromone blend take off at lower thoracic temperatures than males exposed to other stimuli. The take-off temperature of these males was below that for optimal power production in the flight muscles, thus generating a trade-off between rapid departure and suboptimal flight performance. Our results shed light on thermoregulatory behaviour of unrestrained moths associated with the scramble competition for access to females and suggest ecological trade-offs between rapid flight initiation and sub-optimal flight performance.
