众所周知,松材线虫(Bursophelenc-hus xylophilus)在香港地区出现并直接或间接地造成马尾松(Pinus masoniana)和湿地松(P. elliottii)的“骤死”症状.松墨天牛(Monochamus alternatus)被认为是该线虫的主要传播媒介.松墨天牛在香港地区的亚热带气候条件下发育非常迅速,1年完成2-3个世代.由松材线虫为害引起的松树枯萎是香港地区近年来导致松树大量损失的主要因素.
It is well-known that Bursophelenc-hus xylophilus occurs in Hong Kong and causes “sudden death” symptoms, either directly or indirectly, in Pinus masoniana and P. elliottii. Monochamus alternatus) is considered to be the main media of this nematode. Monochamus alternatus develops very rapidly in subtropical climates in Hong Kong for 2-3 generations in one year. The pine wilt caused by the pine wood nematode is the worst in Hong Kong in recent years To lead to a large number of pine loss of the main factors.
