重灾区松材线虫病的治理试验

Control of pine wilt disease in the endemic areas

松材线虫病近距离传播是由松褐天牛自然扩散完成的。通过人工清理病死木结合化学防治,在中心疫区保住了1块松林。实践证明,人工清理后通过有效保护措施,能够控制松材线虫病。

The at-close-range transmission of pine wilt disease was caused by natural expansion of Monochamus alternatus. A piece of pine forest in the center of endemic areas was protected by cleaning up dead pine trees and chemical control in the experiment. The result demonstrated that pine wilt disease could be controlled by effective protection means such as apropriate preventions after manual clearance.
