兴安落叶松鞘蛾性引诱剂应用技术研究

Application technology of sex attractant for control of Coleophora laricella

利用100 ugZ5-10:OH性引诱剂对净月林区兴安落叶松鞘蛾进行引诱试验,结果表明:该性引诱剂对兴安落叶松鞘蛾雄蛾的引诱效果明显,树冠上层诱捕器的诱虫量明显高于树冠中、下层;诱虫量随林分虫口密度的增加而降低。利用性引诱剂可有效监测和防治落叶松鞘蛾。

A sex attracting trail of Coleophora laricella was conducted by using 100 μg2.5 - 10： OH sex attractant in Jingyuetan Forest Farm, Changchun, China. Results show that this kind of sex attractant had an obvious attracting effectiveness to the male Coleophora dahurica. The trapping number of male Coleophora dahurica at the upper crown was significantly higher than that at the middle crown and lower crown; however, the trapping number declined with the increase of population density of the insect in stand. It is concluded that use of sexual attractant can effectively monltor and control Coleophora laricella.
