新疆棉铃虫性信息素的电生理研究

以新疆喀什和库尔勒的棉铃虫为研究对象，利用触角电位记录技术，测定棉铃虫对标准化合物Ｚ１１－１６：ＡＬＤ、Ｚ９－１６：ＡＬＤ、Ｚ１１－１６：ＡＬＤ、１６：ＯＨ、Ｚ１１－１６；ＡＣ的ＥＡＧ反应，发现这些标准化合物均能引起ＥＡＧ反应，其中Ｚ１１－１６；ＡＬＤ能引起最强的ＥＡＧ反应；Ｚ９－１６：ＡＬＤ引起的ＥＡＧ反应次之，由此认为Ｚ１１－１６，ＡＬＤ，Ｚ９－１６：ＡＬＤ反应中，发现在羽化后的前３ｄ棉铃虫对

THE ELECTROPHYSIOLOGICAL STUDIES ON THE SEX PHEROMONE OF THE COTTON BOLLWORM IN XINJIANG

Electroantennograms(EAGs) were recorded from the two areas of male cotton boll worm (Kashi and Kuerle) Helicoverpa armigera in Xinjiang. Z11-16ALD elicited the greatest EAGs among the standard chemical including Z11-16ALD,Z9-16ALD,Z11-16OH,16ALD,16OH and Z11-16AC, each of which could elicit EAG responsiveness, also we concluded that Z11-16;ALD and Z9-16ALD were major sex pheromone components of Helicoverpa armigera in Xinjiang; EAGs to Z11-16ALD decreased with age after keeping high and steady responsiveness in its first three days and EAGs to Z9-16ALD kept steadily, which were consistent with the female calling period that we had disclosed indoors; EAGs to Z11-16ALD, Z9-16ALD, Z11-16OH decreased significantly by successive removal of antennal segments, it was shown that receptors for these compounds were distributed mostly over the distal segment of the five-segmented antennae; Z11-16ALD added with Z11-16OH proportionally will decrease the effect of Z11-16ALD alone, while EAGs to Z11-16;ALD added with Z9-16ALD proportionally did not differ from EAGs to Z11-16ALD alone. This maybe indicates that the effect of Z11-16OH was opposite to Z9-16ALD when both of them were added to Z11-16ALD.
