【摘要】 参照国际上有害生物风险性分析(pest risk analysis,PRA)方法,从定性分析和定量评估两个层面对黄瓜绿斑驳花叶病毒(Cucumber green mottle mosaic virus,CGMMV)的危险性进行了综合评价。从CGMMV的地理分布、侵入后定殖、扩散的可能性等对其进行研究分析,认为CGMMV具有广泛的适宜寄主、极强的适生性及多种传播方式,风险值R为2.39,已给我国葫芦科作物如西瓜造成巨大经济损失,因此断定其定殖、扩散的可能性极高,属于高度危险性的有害生物,应加强对其的风险管理。更多还原

【Abstract】 In accordance with the principles of pest risk analysis(PRA),the risk of Cucumber green mottle mosaic virus(CGMMV) was comprehensively evaluated in view of geographical distribution,possibility of invasion,spreading ways of the virus,etc.The results showed that CGMMV had a wide range of suitable hosts,high vitality and many ways of transmission,and it had caused serious economic losses on cucurbitaceous crops,such as watermelon in our country.The risk assessment value is 2.39.In conclusion,there is high possibility of invasion and spreading for CGMMV in our country,which belongs to the most dangerous pest.The risk management should be done to CGMMV.更多还原
