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。
1999 pine wood nematode was first discovered in Europe and Portugal. Although Portugal’s forestry and quarantine departments tried their best to prevent and control this nematode and its insect-carrying beetle, in 2008 it spread to pine forests in the center of Portugal 200 km away from its original location. At the same time, pine wood nematodes were found on the Spanish border near the city of Cáceres in Portugal. The survey found that although there are many reasons for this nematode’s spread, the main factor is apparently a human factor. In addition, great progress has been made in the bio-ecology of Bursaphelenchus xylophilus and its carriers, the pathogenicity of Bursaphelenchus xylophilus, and the diagnosis and monitoring of molecular biology. The bacteria that cause pine wilt disease carried by pine wood nematodes have recently been discovered. There is an urgent need to quickly and easily monitor the dynamics of trees and nematodes suspected of being infected. Nematode genomics can provide pathological processes for pine wilt disease in the tree.
