松墨天牛对树种取食差异和林区分布情况的影响以及防治

松墨天牛不仅直接危害松树的枝干,而且还会携带松材线虫,对林木生长和林内生态造成严重危害。文章通过探究松墨天牛对马尾松和油松的取食差异,以及在不同林区的数量分布情况,提出了配合使用引诱剂,利用球孢白僵菌、花绒寄甲虫防治松墨天牛的技术。试验结果表明,两种方法均可以有效防治林区内松墨天牛,其中球孢白僵菌的防治效果最为理想。

Monochamus alternatus not only directly does harm to the branches of pine trees,but also carries pine wood nematodes,causing serious harm to tree growth and forest ecology.By exploring the feeding difference of Monochamus alternatus in Pinus massoniana and Pinus tabuliformis,as well as their quantity distribution in different forest areas,this paper puts forward the technology of using Beauveria bassiana and Dastarcus helophoroides,with attractant as the complement,to control Monochamus alternatus.The results showed that the two methods could effectively control Monochamus alternatus in forest area,and the control effect by using Beauveria bassiana was the best.
