摘　　要：植株释放的挥发物能够调节寄主、害虫及天敌三者关系,是植物与害虫协同进化的产物。兴安落叶松挥发物种类虽已确定,但这些物质,特别是受害植株所释放的挥发物对林间昆虫的影响尚不清楚。本研究在3种林龄林分内设置携带受害兴安落叶松枝叶挥发物的诱捕器以考察其对林间昆虫的影响。结果表明挥发物混合物对昆虫诱集效果良好,特别是对天牛类及叶甲类。林龄并未对挥发物的引诱效果造成显著影响,可能与本研究年龄组的划分标准有关。文章指出应将诱集昆虫群落进一步细化,并对关键种或类群进行电生理方面的深入探讨。本文也指出了受害兴安落叶松挥发物混合物发展为植物源农药的前景。Volatile organic compounds （VOCs） evolved during the coevolution of plants and pests and mediate relations among host plants,herbivores and natural enemies.Although the VOCs of Larix gmelini have been identified,their effects,especially from damaged trees on forest insects,are not yet clear.In order to better understand these effects,VOCs from damaged L.gmelini were placed in 3 forest types.The results show that the VOCs were an obvious attractant for forest insects,especially longhorned beetles and leaf beetles.Forest age did not influence these effects significantly,possibly because of the classification of age groups used in the study.The attracted insects require further identification to shed light on the electrophysiological responses of key populations.The potential of VOCs as a future phyto-pesticide is discussed.
