2006—2009年葡萄牙松材线虫(Bursaphelenchus xylophilus)研究进展(英文)

Progress in research on the pinewood nematode(Bursaphelenchus xylophilus),2006-2009

1999年松材线虫在欧洲葡萄牙首次被发现。虽然葡萄牙林业和检疫部门尽力防控了该线虫及其携带昆虫——天牛,但是于2008年还是扩散到距原发现地200 km的葡萄牙中心地带的松林。同时,在西班牙边界临近葡萄牙Cáceres城的边界处也发现了松材线虫。调查发现,虽然该线虫扩散的原因很多,但是主要的因素显然是人为因素。另外,关于松材线虫及其携带者的生物-生态学、松材线虫的致病性及利用分子生物学的诊断和监测等方面取得了较大进展。最近发现了松材线虫携带的导致松萎蔫的细菌。目前急需监测怀疑被浸染的树木及线虫动态的快速方法。线虫基因组学可以提供对松萎蔫病在树体内的病理过程。

The pinewood nematode （PWN） Bursaphelenchus xylophilus was detected for the first time in 1999, in Portugal and Europe, from the Setubal Peninsula. Despite efforts developed by the national forestry and quarantine authorities to control the nematode and its insect vector （Monochamus galloprovincialis ）, the nematode was detected in new forest areas in the center of the country, in 2008, more than 200 km from the original detection site. The nematode was also recently reported to be present in Spain, from a site close to the Portuguese border （Cdceres）. Several reasons may explain the rapid spread of nematode, but the main justification seems to be of human origin, by circulation of non-treated wood and wood products.
