宁波出入境检验检疫局植检实验室在对1批出境的船舶铺垫材料检测时,截获一种伞滑刃属线虫,进行了形态学观察、测量,以及分子鉴定.该线虫属松材线虫组,交合刺较大,长约35~43μm,明显大于松材线虫B.xylophilus、拟松材线虫B.mucronatus、锥尾伞滑刃线虫B.conicaudatus、伪伞滑刃线虫B.fraudulentus和B.luxuriosae等近似种的交合刺,与豆伞滑刃线虫B.doui交合刺34~43μm接近,但该线虫雌虫腹面末端有缺刻,而豆伞滑刃线虫的雌虫靠腹面末端有2~4μm的尾尖突.该线虫ITS-RFLP图谱与新加坡伞滑刃线虫一致,但交合刺比新加坡伞滑刃线虫交合刺41~48μm略小,且其雌虫和雄虫的尾均略长,雌虫尾末端多数有缺刻,而新加坡伞滑刃线虫尾末端钝圆,有短尾尖突.该批铺垫材料来自马来西亚,这是马来西亚除莱奴尔夫伞滑刃线虫外发现的第二种伞滑刃线虫.
Ningbo Port Exit Inspection and Quarantine Bureau of phytosanitary laboratories in a batch of outbound ship bedding material detection, intercepted a kind of umbrella snipe genus Nematode, morphological observation, measurement, and molecular identification of the nematode pine wood nematode group , The intercrossing thorn larger, about 35 ~ 43μm, significantly larger than B. xylophilus, B.mucronatus, B.conicaudatus, B.fraudulentus and B. Luxuriosae and other similar species of hybrid spur, and B. brasiliensis Interspecies B. doui hybridization 34 ~ 43μm close, but the nematode female ventral surface of the nick, while the Eurasian worm Ureaplasma verrucosa by the end of the ventral 2 ~ 4μm . The ITS-RFLP pattern of the nematode was consistent with that of S. elegans, but the cross was slightly smaller than that of S. aurantiaca at 41-48 μm, and the females and males had slightly longer tails. The female Most of the end of the tail is notched, while the Singapore umbrella sliver worm tail end obtuse, short tail crescent.This batch of bedding material from Malaysia, which is Malaysia in addition to Lekurf umbrella umbrella edgeworm found the second umbrella slip Knife nematodes.
