该文重点对近2 a日本松材线虫病的研究文献进行整理分析。目前松材线虫病的研究仍是日本国森林病虫害的主要研究课题。在松树的抗(感)病机理、线虫在树体内的活动与增殖规律、线虫与天牛的关系、生物防治以及新技术在研究中的应用等方面取得较大进展。

At present, many research works focus on forest pest fields in Japan. The related research papers, in which the studies on proportion, status and trend of pine wood nematode were reported in recent years, were reviewed and analyzed. The research progress of pine wood nematode in aspects of disease-resistant mechanism, pattern of activities and proliferation of the nematode in tree （trunk）, the relationship between nematode and longicorn, biological control and application of the new technologies in the research fields were discussed.
