雌性玉米穗虫 Heliothis zea (Boddie) 的产卵器仅在暗期才含有大量可提取的性信息素。对产卵器提取物（Z）-11-十六碳烯醛（该物种的主要信息素成分）的定量气相色谱分析表明，雌性性信息素效价在成虫羽化后第三晚达到最大。雌性在第三个晚上开始在暗期开始后 1 小时内开始鸣叫，并且鸣叫活动的峰值与最大信息素滴度一致。与同龄的处女雌性相比，第三晚交配导致信息素滴度降低了93%。交配的雌性的滴度在随后的夜晚中增加，三天后与同龄的处女雌性的滴度相似。
Ovipositors of the female corn earworm, Heliothis zea (Boddie), contained large amounts of extractable sex pheromone only during scotophase. Quantitative gas chromatographic analysis of ovipositor extracts for (Z)-11-hexadecenal, the species' major pheromonal component, indicated that female sex pheromone titer was maximal on the third night after adult emergence. Females in their third night began calling within 1 h after onset of scotophase, and peak calling activity coincided with maximal pheromone titer. Compared to that of virgin females of similar age, mating on the third night caused a 93% reduction in pheromone titer. Titer in mated females increased during subsequent nights, and 3 days later it was similar to that of virgin females of the same age.
