松材线虫病综合治理引诱技术对天牛种群的影响

应用综合治理措施对天目湖景区的松褐天牛和短角幽天牛等两种天牛进行了连年诱捕试验和监测,数据显示,松褐天牛和短角幽天牛种群密度均有显著下降.2007年松褐天牛平均诱捕量较2005年下降了65.08%,2007年短角幽天牛平均诱捕量较2006年下降了31.69%,表明综合治理技术对松树蛀干类害虫具有良好的控制效果.同时,对松材线虫病也有明显的控制作用.

Influence of Trapping Techniques to Population of Pine Sawyer Beetles in Bursaphelenchus xylophillus Comprehensive Management Demonstration Area

The test of attraction and monitoring on Monochamus alternatus and Spondylis buprestoides were conducted in Tianmuhu Lake, Jiangsu, The results showed that the population density in both Monochamus alternatus and Spondylis buprestoides was decreased significantly by the comprehensive managements. The average trapping amount of M. alternatus in 2007 was decreased by 65, 08% compared with in 2005, and the average trapping amount of S. buprestoides in 2007 was decreased by 31.69% compared with in 2006. This indicated that the comprehensive managements were very efficient in controlling pine sawyer beetles. And the managements were also obvious effects to control Bursaphelenchus xylophillus.
