首次截获的安东尼伞滑刃线虫的鉴定

Identification of Bursaphelenchus antoniae from imported wooden package

宁波出入境检验检疫局植检实验室于2007年2月从来自法国的木质包装中截获一种伞滑刃属线虫。该线虫虫体较短,侧区有2条侧线,雄虫交合刺强壮,强烈弯曲,基顶高圆,喙突指状。雌虫有小阴门盖,尾圆锥形渐细,较平直或略向腹面弯曲,末端尖或钝圆,与树皮象伞滑刃线虫十分接近。经形态学比较、测量以及ITS-RFLP图谱比对,鉴定为安东尼伞滑刃线虫(Bursaphelenchus antoniae)。目前除葡萄牙外未见该线虫的报道。
