摘要
根据国际植物检疫措施标准(ISPM)规定的有害生物风险性分析(PRA)程序,利用相关风险性分析模型,从国内外分布状况、潜在的危害性、受害栽培寄主的经济重要性、传播扩散的可能性及危险性管理难度5个方面对三叶斑潜蝇在我国的风险性进行定性、定量分析,其综合风险值R为2.15,符合检疫性有害生物的条件,据此提出了2条相关风险管理备选对策,并进行效率和影响分析,以期使风险减少到可接受的水平。
Based on the rule of pest risk analysis (PRA) of international standards for pest measurements (ISPM) and the relational model of PRA, this paper dealt with the quantitative and qualitative analysis of the risk level of Liriomyza trifolii (Burgess) in five aspects-distribution, potential damaged degree, economical value of damaged host plants, spreading possibility and risk management difficulty in China. The value of the synthetical index of the pest risk is 2. 15, which has reached the level of the quarantine pest in China. Based on this result two strategies were evaluated and proposed for better risk management in order to reduce the risk to acceptable level.
