飞蛾的性信息素通讯有助于了解生殖隔离和物种形成的机制。棉铃虫和 Assulta 使用 (Z)-11-十六烯醛 (Z11-16:Ald) 和 (Z)-9-十六烯醛 (Z9-16:Ald) 作为信息素成分，比例相反，分别为 97:3 和 5:95。棉铃虫的性信息素腺中也会产生微量的 (Z)-9-十四烯醛 (Z9-14:Ald)，但棉铃虫则不会。风洞研究表明，在棉铃虫的主要信息素混合物中添加少量（0.3%）的 Z9-14:Ald 会增加雄性的吸引力，但在较高剂量（1%、10%）时，相同的化合物会起到抑制剂的作用。在 H. assulta 中，Z9-14:Ald 在信息素混合物中的浓度为 1% 时会降低雄性吸引力，但在较低浓度 (0.3%) 下则无效。通过单感器记录鉴定了触角中三种类型 (A–C) 的毛感器，分别响应 Z11-16:Ald、Z9-14:Ald 以及 Z9-16:Ald 和 Z9-14:Ald。触角叶（AL）的钙成像显示，这三种化学物质的输入信息被传输到两个物种的触角叶中的巨肾小球复合体（MGC）的三个单元：一个大肾小球用于主要信息素成分，一个小肾小球用于次要信息素成分，第三个肾小球用于行为拮抗剂。调节至 Z11-16:Ald 和 Z9-16:Ald 的 A 型和 C 型神经元在两个物种之间的 MGC 中具有相反的目标。在棉铃虫中，低剂量（1、10 μg）的 Z9-14:Ald 主要激活处理次要信息素成分的肾小球，而较高剂量（100 μg）也会在拮抗性肾小球中引起相同的活性。相反，在 H. assulta 中，Z9-14:Ald 总是强烈激活拮抗性肾小球。这些结果表明，Z9-14:Ald 通过激活功能不同的嗅觉通路，在两种 Helicoverpa 物种的性交流中发挥着不同的作用。
Sex pheromone communication of moths helps to understand the mechanisms underlying reproductive isolation and speciation. Helicoverpa armigera and Helicoverpa assulta use (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-9-hexadecenal (Z9-16:Ald) as pheromone components in reversed ratios, 97:3 and 5:95, respectively. H. armigera also produces trace amount of (Z)-9-tetradecenal (Z9-14:Ald) in the sex pheromone gland, but H. assulta does not. Wind tunnel studies revealed that the addition of small amounts (0.3%) of Z9-14:Ald to the main pheromone blend of H. armigera increased the males' attraction, but at higher doses (1%, 10%) the same compound acted as an inhibitor. In H. assulta, Z9-14:Ald reduced male attraction when presented as 1% to the pheromone blend, but was ineffective at lower concentrations (0.3%). Three types (A–C) of sensilla trichodea in antennae were identified by single sensillum recording, responding to Z11-16:Ald, Z9-14:Ald, and both Z9-16:Ald and Z9-14:Ald, respectively. Calcium imaging in the antennal lobes (ALs) revealed that the input information of the three chemicals was transmitted to three units of the macroglomerular complex (MGC) in ALs in both species: a large glomerulus for the major pheromone components, a small one for the minor pheromone components, and a third one for the behavioral antagonists. The type A and C neurons tuned to Z11-16:Ald and Z9-16:Ald had a reversed target in the MGC between the two species. In H. armigera, low doses (1, 10 μg) of Z9-14:Ald dominantly activated the glomerulus which processes the minor pheromone component, while a higher dose (100 μg) also evoked an equal activity in the antagonistic glomerulus. In H. assulta, instead, Z9-14:Ald always strongly activated the antagonistic glomerulus. These results suggest that Z9-14:Ald plays different roles in the sexual communication of two Helicoverpa species through activation of functionally different olfactory pathways.
