北京地区的烟青虫(Helicover Pa asslta Cucn(?)e)的性信息素腺体提取物经毛细管柱气相色谱分析及GC MS分析,鉴定了6种组分.这6种组分为:十六醛(16:Ald)、顺 9—十六烯醛(Z9—16:Ald)、顺11—十六烯醛(Zll 16:Ald)、顺9—十六烯醇(Z9-16:OH)、顺11—十六烯醇(Zll-16:OH)、顺9—十六烯基乙酸酯(Z9 16:OAc),比例为10.9:58.7:3.9:14.7:1.1:10.7.田间试验表明,只有16:Ald、Z9 16:Ald和Zll 16:Ald(比例为15.3:79.2:5.5)组成的三组分诱芯和Z9—16:Ald和Zll—16:Ald(比例为93.4:6.6)组成的两组分诱芯对于雄蛾有强烈的引诱活性.在3种醛为组分的诱芯中加入Z9 16:OH明显地降低引诱活性.
The sex pheromone glands extracts of Helicoverpa asslta Cucn (?) E in Beijing were characterized by capillary gas chromatography and GC-MS and identified six components: sixteen Hexadecenal (Z9-16: OH), cis-hexadecenal (Z9-16: Ald), cis- (Z11-16: OH), cis 9-hexadecenyl acetate (Z9 16: OAc) in a ratio of 10.9: 58.7: 3.9: 14.7: 1.1: 10.7. Field trials have shown that , With only three components of 16: Ald, Z9 16: Ald and Zll 16: Ald (ratio 15.3: 79.2: 5.5) and Z9-16: Ald and Z11-16: Ald (93.4: 6.6 ratio) The two-component lure composed of strong attractant activity to male moths.The addition of Z9 16: OH to the three aldehyde-containing components induced a significant decrease in attractant activity.
