摘要
豆伞滑刃线虫由宁波出入境检验检疫局植检室验室于2004年6月首次从台湾的针叶木质包装中截获并报道以来,至今共截获17批次,分别来自韩国(6批次)、中国台湾(4批次),日本(4批次),印度(1批次),马来西亚(1批次)和南非(1批次)。该线虫属松材线虫组,与拟松材线虫、松材线虫等十分接近。其主要鉴定特征是:雌虫尾圆锥形略向腹面弯曲,其腹面的边线较平直,而背面的边线明显呈圆弧形;尾尖长约2～4μm,渐细,有时呈丝状,位于腹面;雄虫交合刺较大(约36～40μm),中间部分几乎呈直线。该线虫很容易与拟松材线虫等混淆,当形态学鉴定有困难时,ITS-RFLP方法是十分有效的辅助手段。我国大陆尚未有该线虫发生的报道。
Bursaphelenchus doui Braasch,Gu,Burgermeister and Zhang,2004 was detected in coniferous wooden package for the first time from Taiwan in June,2004.Since then,it was detected in 17 batches of wooden package imported from South Korea(6 batches),Taiwan(4 batches),Japan(4 batches),India(1 batch),Malaysia(1 batch)and South Africa(1 batch).It obviously belongs to the xylophilus group,especialy similar with B.xylophilus and B.mucronatus.The most important identify characters are that the female tail has a moderately narrowing to a slightly ventrally bent terminus with a distinct mucro of 2～4μm length that tapers,sometimes appearing hairlike,and the male spicules are quite large,atout 36～40μm,the middle part nearly strait.When it is difficult to make identification,ITS-RFLP methods is effective.Up to now this species has not been reported in China mainland.
