Situation of Bursaphelenchus xylophilus in China
A survey had shown previously that Bursaphelenchus xylophilus (EPPO A1 quarantine pest) was only present in Jiansu province around the cities of Nanjing and Zhenjiang (1992, EPPO RS 520/19). Since then, B. xylophilus has been isolated from the wood of dead Pinus thunbergii and P. massoniana, in the nearby province of Zhejiang (in Dancheng Town, Xiangshan County, Ningbo city), in August 1991.
