The behavioral function of a pheromone released by males of the army-worm moth Pseudaletia unipuncta was investigated both in laboratory wind-tunnel experiments and in experiments with moth-baited traps in the field. Such male moth scents have been thought to act at close range as sexual stimulants for females of the same species. However, the only obvious effect of the P. unipuncta male pheromone was upon other males, decreasing their tendency to approach sexually receptive, pheromone-releasing females and to exhibit copulatory behavior when near those females. The adaptive significance of the male pheromone may be related to the increased reproductive efficiency that results if multiple males are prevented from competing for a single female.
我们研究了粘虫拟步行甲雄蛾释放的信息素的行为功能，分别在实验室风洞实验和田间诱蛾陷阱实验中进行。人们认为这种雄蛾气味在近距离内作为同种雌蛾的性刺激物起作用。然而，粘虫拟步行甲雄蛾信息素唯一明显的作用是对其他雄蛾起作用，降低它们接近有性接受能力、释放信息素的雌蛾的倾向，并在接近这些雌蛾时减少表现交配行为的倾向。雄蛾信息素的适应意义可能与以下情况有关，如果多个雄蛾被阻止与单个雌蛾竞争，会导致繁殖效率提高。
