摘  要：
对拟松材线虫的形态以及致病性方面的研究进行了综述。拟松材线虫在形态上与松材线虫十分相似。两者之间的主要区别在于拟松材线虫的尾部形态为圆锥形,而松材线虫的尾部为指形。形态鉴定上支持将尾尖突短于1μm的定性为松材线虫,长于3.5μm的定为拟松材线虫。拟松材线虫和松材线虫交合伞都有多种变化,不宜作为分类特征。关于拟松材线虫对松树的致病性,主要存在3种观点:①无致病性;②有微弱致病性或潜在致病性;③具有致病性分化,有的株系具有较强的致病性。

摘  要：
In this paper,we have made a comprehensive summary of the Bursaphelenchus mucronatus phenotype and pathogenicity.B.mucronatus was similar to B.xyluphilus in their shapes.The main differences between these two species were their tail shapes,of which the B.mucronatus was conical,and B.xyluphilus was round tail.Actually,the species with the length of terminal mucro less than 1 μm was defined as B.xyluphilus,and with the length of terminal mucro more than 3.5 μm was B.mucronatus,and the bursa was not a proper characteristic classification because of its diversity and uncertainty.There were three main opinions about pathogenicity of B.mucronatus which conveyed as follows: no pathogenicity,weak or potential pathogenicity,and strongest pathogenicity.
