摘要
为确定椰心叶甲科学的检疫管理措施,根据 WTO 的《卫生与植物卫生措施协定》(SPS)要求,对其进行风险性分析。依据国际植物检疫措施标准(ISPM)规定的有害生物风险分析(PRA)程序,利用相关模型,对各项分析指标进行分析并赋值运算。各分析指标及运算值为:(1)国内分布情况,风险值为2;(2)潜在的经济危害性,风险值为2;(3)寄主植物的经济重要性,风险值为3;(4)传播扩散的可能性,风险值为2.05;(5)风险管理难度,风险值为1.66。椰心叶甲的综合风险性值为2.09,符合高风险检疫性害虫条件,据此提出2条相关风险管理备选方案,并分别进行效率和影响评估,确定最终风险管理方案。
According to the implementation of “Agreement on the Application of Sanitary and Phytosanitary （SPS） Measures” of WTO, the risk of the invasive pest, Brontispa longissima （Gestro） in China was analyzed in order to finalize the policy for the quarantine management of the pest. Based on the rules of pest risk analysis （PRA） of “International Standards for Pest Measurements” （ISPM） and the relational model of PRA, we categorized the risk level of Brontispa longissima using five indexes： the distribution, the potential degree of damage, the economical value of infected host plants, the possibility of transmission and spreading, and the difficulty of risk management in China. The values of the five indexes were calculated as 2, 2, 3, 2.05 and 1.66, respectively. The overall risk value of Brontispa longissima was 2.09, which has reached the level of the high risk quarantine pest in China. Finally, two strategies of the risk management for Brontispa longissima were evaluated and the better one was proposed.
