摘要
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,建立棕榈象甲入侵风险分析评估模型,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,国内分布情况(P1),风险值为3;潜在的经济危害性(P2),风险值为2.6;寄主植物的经济重要性(P3),风险值为3;传播扩散的可能性(P4),风险值为1.64;风险管理难度(P5),风险值为2.33。棕榈象甲的综合风险性值为2.46,符合高风险检疫性害虫条件,对我国的棕榈科植物威胁很大。
Based on the international standards for pest measurements(ISPM),the pest risk analysis(PRA) model of Rhynchophorus palmarum in China has been established by using the following five indexes:the distribution,the potential degree of damage to economy,the economic value of infected host plants,the possibility of transmission and spreading,and the difficulty of risk management in China.The values of these five indexes were calculated as 3,2.6,3,1.64 and 2.33,respectively.The overall risk value of R.palmarum in China was 2.46,which has reached the level of high-risky quarantinable pests in China.The weevil can settle down easily in China and will pose a great threat on palm trees.
