Taxonomy of Pine Wood Nematode Species

The plant parasitic nematodes have been found in most of terrestrial plants, all over the world. The most classical example of a nematode species causing tremendous losses to pines in Japan and some other countries is that of Bursaphelenchus xylophilus. Pine wilt disease has become one of the most serious problems for pine forests in east and south region of China. During a faunatic survey, thirteen nematode species belonging to five genera have been described and illustrated. Identification was carried out with a combination of morphological and morphometric characters assisted by molecular analysis of ITS-RFLP patterns. Based on the information gained from the survey it is observed that among thirteen species the pine wood nematode was found to be the dominant species and its occurrence lead to significant weakness in diversities of nematodes within pinewood.
