| 摘 要： | 本文用单细胞电反应的记录方法，测定了棉铃虫Heliothis armigera Hubner雄蛾触角的毛形感器对其性信息素组分及雌蛾腹部提取物的反应，发现顺-11-十六碳烯醛和顺-9-十六碳烯醛能引起反应。对前者发放大脉冲，对后者发放小脉冲，对雌蛾腹部提取物发放大、小两种脉冲，但以大脉冲为主。

| Abstract: | Electrophysiological recordings of responses to its sex pheromone components from single olfactory receptor cells were carried out in the male cotton bollworm, Heliothis armigcra. The sensory cells of the longest trichiform sensilla responded specifically to the pheromone components lested. Only two types of receptor neurons were found by inference of the measurements, each tuned to one of the female-pro-duced components. The majority of the neurons were tuned to the major component (Z)-ll-hexadecenal (Z-l1-16:A1), which fired large spikes. Another group of neu-rons responded specifically to the stimulation with (Z)-9-hexadecenal (Z-9-16: Al), which fired small spikes. Electrophysiological recordings from these sensilla showed that (Z)-l1-hexadecenal is a major component, (Z)-9-hexadecenal is a minor com-ponent. |
