摘要
我国大陆自１９８２年在南京中山陵发现松材线虫（Ｂｕｒｓａｐｈｅｌｅｎｃｈｕｓｘｙｌｏｐｈｉｌｕｓ），至今在我国总计有６省１地区发生，致死松树一百多万株，成为我国有史以来的特大森林病害。由于进行了大力防治，已将此病控制在一定危害水平上。对照日本国松材线虫病发生发展的历史，沉痛教训提醒人们，如不加重视，我国有可能重蹈日本覆辙。分析我国目前所采用的防治措施后，提出严格检疫和长度清理病死树为主的综合防治措施，以及区别情况分别对策。以江苏省为例，可将疫区区划为中心疫区、疫区边缘和孤立疫点郊市县，采取不同的防治措施。此对策是建立在分析该病害三要素和该病害侵染循环３个环节与病害防治关系的理论基础之上的。
The pine wilt disease caused by nematode,Bursaphelenchus xylophilus was first detected inZhongshan Mausoleum,Nanjing in 1982 and the disease quickly spread to ten nearby counties,administratively belonging to the cities of Nanjing and Zhenjiang.In the recent 10 years,it hasdestoryed 100,0000 pine trees and therefore has become the greatest threat to pine stands in thehistory of China’s forestry. Fortunately,this disedse has been brought under control due to inten-sive control measures taken so far.The destructive occurrence and spread of the disease in Japanwarns us that the same catastrophe can happen in China if inadequate attention is paid.In this pa-per,a systematic analysiS on the effects of all the control measures used at present is made and acontrol strategy of strict quarantine and thorough disposel of dead pine trees is proposed.withJiangsu as an example,the infested region is divided into epicenter,margin and other scattered in-fested areas in nearby cities and counties,and different coritrol measures should be taken in theseareas according to different degrees of infestation,This strategy is based on the principle that therecxists a correlation between the three factors and three stages of the infective cycle and its controlof this disease.
