We report the identification of the southwestern corn borer,Diatraea grandiosella Dyar (Lepidoptera: Pyralidae), female sex attractant pheromone as a mixture of (Z)-9-hexadecenal, (Z)-11-hexadecenal, and (Z)-13-octadecenal in the ratio 21.5∶70.6∶7.9. Initially, six 16- and 18-carbon aldehydes includingn-hexadecanal, (Z)-9-octadecenal, (Z)-11-octadecenal, and the three above were isolated from female gland rinses and evaluated as potential pheromone components by GLC-MS and laboratory bioassays. By laboratory flight chamber and field tests, the stated mixture of (Z)-9-hexadecenal, (Z)-11-hexadecenal, and (Z)-13-octadecenal was shown to be as effective as the female for male attraction. Electrophysiological studies confirmed the requirement for these three compounds, but not forn-hexadecanal, (Z)-9-octadecenal, and (Z)-11-octadecenal.
我们报告了西南玉米螟（Diatraea grandiosella Dyar）（鳞翅目：Pyralidae）雌性性信息素的鉴定，它是一种（Z）-9-十六碳烯醛、（Z）-11-十六碳烯醛和（Z）-13-十八碳烯醛的混合物，比例为 21.5∶70.6∶7.9。最初，从雌性腺冲洗液中分离出六种 16 和 18 碳醛，包括正十六烷醛、（Z）-9-十八碳烯醛、（Z）-11-十八碳烯醛和上述三种醛，并通过 GLC-MS 和实验室生物测定评估为潜在的信息素成分。通过实验室飞行室和田间试验表明，（Z）-9-十六碳烯醛、（Z）-11-十六碳烯醛和（Z）-13-十八碳烯醛的混合物与雌性对雄性的吸引力一样有效。电生理研究证实了这三种化合物的需求，但不需要正十六烷醛、（Z）-9-十八碳烯醛和（Z）-11-十八碳烯醛。
