摘要:
 在对秦岭林区华山松大小蠹危害调查的基础上,针对秦岭森林生态系统的特异性和华山松大小蠹发生的情况,探索适合秦岭森林生态系统的华山松大小蠹引诱剂林间释放技术。结果表明:1)秦岭林区半阴坡和半阳坡的华山松更易遭受华山松大小蠹的入侵,华山松大小蠹交配模式为一雌一雄和一雌二雄2种模式。2)对华山松和华山松大小蠹消化道挥发性物质主要成分活性检测的基础上,构建的引诱剂配方B(α-phellandrene:(S)-(-)-α-pinene:camphene=2∶1∶1)、H(α-phellandrene:(S)-(-)-α-pinene:camphene=2∶3∶2)和I(α-phellandrene:(S)-(-)-α-pinene:camphene=1∶1∶1)对华山松大小蠹的引诱效果明显大于其他6种配方,引诱剂配方B对雌雄虫引诱效果有显著性差异。3) 对不同位点诱捕器悬挂引诱效果的比较结果表明,受害林林内和林间小路的诱捕效果最好,林缘和林外10 m诱捕效果次之,林外50 m效果最差。
Abstract:
 The technology of releasing attractants in Qinling forest ecosystem for trapping Dendroctonus armandi was explored based on the investigations of the occurrence of the pest in Pinus armandi and the unique characteristics of the forest ecosystem in Qinling Mountains.The results were as follows.1)Half shady slope and half sunny slope were more favorable for D.armandi in Qinling experimental forest.The mating patterns of D.armandi were monogamous or one female to two male.2)An attractant formulae was developed based on the field detection on the bioactive volatiles released from Pinus armandi and those from D.armandi hindgut.Formula B was consisted of α-phellandrene:(S)-(-)-α-pinene:camphene with a proportion of 2∶1∶1,formula H was α-phellandrene:(S)-(-)-α-pinene:camphene=2∶3∶2,and formula I was made up of α-phellandrene:(S)-(-)-α-pinene:camphene=1∶1∶1.The three formulae developed were better than the other six attractants tested.Significant difference in attracting male and female pests were observed for formula B.3)For the site of trap hanging,the trapping effect was the best when traps were hanged within the forest and on the forest roads,followed by hanging in the forest edge or 10 m out the forest,the effect was the worst when the traps were hanged 50 m outside the forest.
