福建松墨天牛调查及其危害病树的早期诊断方法

Survey on Monochamus alternatus in Fujian and a Method for Early Diagnosis on Imperiled Pine

为了解松材线虫病媒介松墨天牛在福建的分布和数量 ,以及病原线虫的存在情况 ,对宁德、莆田、漳州和厦门等地区部分林场进行了调查 .目前仅在仙游的溪口发现松墨天牛密度较高的分布地点 .在直径为 10～ 18cm,长约 30～ 4 5cm的松树树干中羽化出木的松墨天牛在 4～ 8头之间 .报道一种早期诊断被松墨天牛感染的病树的简便方法 .

Survey on distribution and amount of pine wilt vector Monochamus alternatus in southern Fujian were conducted from May 1998 to Oct.,1999. The result shows that only Xikou forestry centre in Xianyou city has relatively high density of M. alternatus. The logs, 10 to 18 cm in diam., 30 to 45 cm long, carried 4 to 8 beetles.
