危险性有害生物椰子织蛾入侵福建的风险性分析(英文)

介绍了运用国际植物检疫措施实施标准(ISPM)的有害生物风险分析(PRA)程序,建立椰子织蛾传入风险分析评估模型,采用定性分析和多指标综合评估相结合的方法进行分析。结果显示,福建省分布情况,风险值为3;潜在的经济危害性,风险值为2.0;寄主植物的经济重要性,风险值为3;传播扩散的可能性,风险值为1.78;风险管理难度,风险值为2。椰子织蛾的综合风险性值为2.3,符合高度危险的外来有害生物条件,已在我国海南、广东、广西等地区定殖,对福建省的棕榈科植物威胁很大,建议将叶子织蛾列入福建省补充林业检疫性有害生物名单中,加强检疫管理、监测和控制工作,严防其传播和扩散危害。

Risk Analysis of Opisina arenosella Walker in Fujian Province

Opisina arenosella Walker is a dangerous pest which invaded our country in recent days.Based on the international standards for pest measurements（ISPM）,pest risk analysis （PRA） model has been established in this paper.The risk level of Opisina arenosella in Fujian Province was comprehensively evaluated by the following five indexes：the distribution,the potential degree of damage,the economic value of the infected host plants,the possibility of transmission and spreading and the difficulty of risk management.The risk values of the five indexes were calculated as 3,2.0,3,1.78 and 2,respectively.The overall risk value of the pest was 2.3,which has reached the level of high-risk pests in Fujian.The pest has easily settled down in the three provinces of China,such as Hainan,Guangdong and Guangxi,and will pose a great threat on palm trees in Fujian.It is suggested that Opisina arenosella be included in the forestry quarantine harmful pest list of Fujian province and the quarantine management,monitoring and control of the work strengthened,in order to prevent the spread and proliferation of harm.
