福建省松树线虫的研究 I.松干伞真滑刃线虫的种类

Studies on Pine-parasitic Nematodes in Fujian I.Species of Bursaphelenchus Genus on Pine Stem

自2001年7月至2002年12月在福建省各地共采集松树木质部样品256份,分离发现88份(34%)样品中含有伞真滑刃属Bursaphelenchus的线虫8种,本文先报道其中的4种:拟松材线虫Bursaphelenchus mucronatusMamiya&En-da,1979、赫列尼克斯伞真滑刃线虫B.hellenicus SkarmoutsosG.et al.,1998、霍夫曼尼伞真滑刃线虫B.hofmanniBra-asch,H.,1998、奇异伞真滑刃线虫B.aberransFang,et al.,2002.

A survey of nematodes living in pine wood in Fujian province,China was conducted from July 2001 to December 2002. Eight species of Bursaphelenchus were discovered in 88 samples of Pinus Massoniana wood （34%） among 256 pine wood samples collected from Xiamen, Nanping,Longyan and other places of Fujian province. We report 4 species first：Bursaphelenchus rnucronatus Mamiya ＆ Enda, 1979 ,B. hellenicus Skarmoutsos G. et al. , 1998 ,B. hofmanni Braasch, H. , 1998 ,B. aberrans Fang,et al. ,2002. The Xiamen population of B. mucronatus is similar to Japan population,but different from Nanjing population; The Xiamen population of B. hellenicus is smaller than Greece population while its stylet is longer; The body length of Xiamen population of B. hofmanni is shorter than that of Germany population and its spicules length is shorter too; The Xiamen population of B. aberrans is similar to Guangdong population. B. hellenicus and B. hofmanni are discovered for the first time from China.
