从新加坡进境阔叶木质包装中分离到伞滑刃属松材线虫组新种——新加坡伞滑刃线虫。该线虫雌虫和雄虫体长分别为850(690～961)μm和792(553～950)μm,身体较粗壮,口针15～16μm,侧区有4条侧线,雌虫后阴子宫囊较长(平均102μm),尾部圆锥形(c=20),略向腹面弯曲,末端钝圆,或有极短的尾尖突(1～2μm),雄虫交合刺长(41～48μm),喙突显著,远端有盘状突。该线虫与松材线虫组的B.conicaudatus、B.luxuriosae、B.fraudulentus、B.kolymensis、B.baujardi、B.xylophilus、B.mucronatus及B.abruptus形态上近似,但可从较大的交合刺及雌虫尾部形态来区分。另外用ITS—RFLP方法也可将该线虫区分出来。
A new species of Bursaphelenchus xylophilus from Singapore imported broad-leaved wood packaging was isolated from Singaporean Bursaphelenchus xylophilus. The nematodes and males had body lengths of 850 (690 ~ 961) μm and 792 (553 ~ 950) μm, respectively, with a thicker body with 15 ~ 16μm acupuncture points and 4 lateral lines in the lateral area. (Averaging 102μm) and caudal conic (c = 20), slightly curved to the ventral surface, rounded at the end, with very short cusps (1-2μm), male spikes (41-48μm) Prominent, distal disc-shaped process. The nematodes are morphologically similar to B.conicaudatus, B.luxuriosae, B.fraudulentus, B.kolymensis, B.baujardi, B.xylophilus, B.mucronatus and B.abruptus in the pine wood nematode group, but may be morphologically similar to larger ones Thorn and female tail to distinguish the form. In addition, the ITS-RFLP method can distinguish the nematodes.
