松树萎蔫病是林业生产的一大威胁。1972年Mamiya等人确认线虫是萎蔫病的病原,并认为这种线虫是伞滑刃线虫属的一个新种,定名为Bursaphelenchuslignicolus。1981年经Nickle等人鉴定,确认B.lignicolus是B.xylophilus的同义名。1979年Mamiya等人报道了在松树上发现的另一个新种B.mucronatus,但认 Pine wilt disease is a major threat to forestry production. In 1972, Mamiya et al. Confirmed that the nematode is the etiological agent of wilting disease and considered this nematode as a new species of Bursaphelenchus lignicolus. Nickle et al identified in 1981 to confirm that B.lignicolus is synonymous with B.xylophilus. In 1979, Mamiya et al. Reported B.mucronatus, another new species found on pine trees. However,
