摘要：从松材线虫病在我国发生危害的状况、松材线虫Bursaphelenchus xylophilus(Steiner&Buhrer)Nickle的遗传学基础与扩散流行的生物学基础等方面分析了松材线虫入侵扩张的趋势。基于松材线虫的起源、极强的环境适应性、寄主植物的多样分布、媒介昆虫的广泛存在及经济物流等活动的高速发展,作者认为我国绝大多数松林都易感松材线虫,辽宁、吉林和内蒙古等地区面临松材线虫入侵扩张的高风险,北京和天津处在包围之中,中温带是当前防控的前线,形势危急严峻。建议加强监测预警和迅速开展应急防控技术研究。
The trend of invasion and expansion of Bursaphelenchus xylophilus was analyzed from the situation of pine wood nematode disease in China,the genetic basis of B.xylophilus and the biological basis of diffusion and epidemic.Based on the origin,strong environmental adaptability,diverse distribution of host plants,the widespread existence of vector insects of B.xylophilus and the rapid development of economic logistics,it is believed that most pine forests in China are susceptible to pine wood nematodes.Liaoning Province,Jilin Province and Inner Mongolia Autonomous Region are facing the high risk of invasion and expansion of B.xylophilus.Beijing and Tianjin are surrounded.The medium temperature zone is the front line of current prevention and control,and the situation is critical.It is recommended to strengthen monitoring and early warning,and to carry out research on emergency prevention and control technology rapidly.
