摘　　要：连续两年定期监测、调查采样和鉴定证明：每年６～１０月出现的松材线虫病Ｂｕｒｓａｐｈｅｌｅｎｃｈｕｓｘｙｌｏｐｈｉｌｕｓ致死松树上，松褐天牛Ｍｏｎｏｃｈａｍｕｓａｌｔｅｒｎａｔｕｓ虫株率为１００％，而１１月至次年５月间出现的病死株上，虫株率为零。对前者应集中砍除，并加以严格的除害处理；后者可经剥皮处理后在疫情发生区内加工利用。It is shown by regular monitoring,investigation and identification of two years that the ratio of dead pine trees containing M.alternatus is 100% from June to October each year,but the ratio of that is 0 from November to the next May.The optimium controlling method is large scale felling and strict treatment for the former trees,for the later ones is peeling off the bark and process utilization or taken as trap trees partially.
