摘要
松材线虫病是松树最危险的病害之一,在世界上一些国家都有发生并且损失惨重。寄主松树感染松材线虫[Bursaphelenchus xylophiluz(Steiner&Buhrer)Nickle]40天后即可死亡。我国自1982年在南京中山陵风景区首次发现以来,到2000年底,因病枯死的松树达到2000多万株,直接经济损失25亿元,间接损失250亿元。松材线虫侵入寄主(主要是松树)后,在其体内迁移、分布及其引起的寄主内部细胞学、组织学的变化。病害发展过程与致病相关性。
Pine wilt disease caused by pine wood nematode is the most serious forest disease in the world, which induces rapid wilt of pine. It have brought great damage to forest resources, natural landscape and ecological environment in our country. Some studies showed that dispersal of pine wood nematode inside pine trees and its changes to host cells and histopathology were related to pathogenicity of pine.
