摘　　要：松树是我国重要的造林先锋树种与景观绿化树种,然而,近年来在许多地方发现有不明原因、不同症状的枯萎松树,不同种类的寄生线虫在枯萎松树中被发现。笔者对松树体内的寄生线虫以及这些寄生线虫的致病性进行了综述。到目前为止,在我国松树上已经发现寄生线虫有11属42种以及11个未定种。除松材线虫外,一些线虫如拟松材线虫、Bursaphelenchus sexdentati等也能够引起某些松树的死亡。Pine was an important pioneer tree for afforestation and landscape greening in China. But during recently years, pine wilting of unclear cause and with different appearances was observed in many places. Various species of parasitic nematode were found in wilting pine trees. In this paper, species of parasitic nematode in pine host and their pathogenicity were reviewed. Up to now, forty-two species and eleven indeterminatae species, which belong to eleven genus,,were found in China. Besides Bursaphelenchus xylophilus, some species such as B. mucronatus and B. sexdentati could cause a little damage to some species pine trees.
