枣实蝇在陕西省的风险性分析及检疫对策

为了评估枣实蝇(Carpomya vesuviana Costa.)在陕西危害枣果的潜在危险性。以制定科学的检疫对策，参照国际上的有害生物风险分析方法，结合陕西省枣树资源分布情况，对枣实蝇在陕西省的3个地理区域进行了风险性分析。结果表明：枣实蝇在陕北、关中和陕南的评估风险性R值分别为2.239、2.065、1.469，枣实蝇在陕北和关中为高度危险性害虫，在陕南为低度危险性害虫。鉴于栆实蝇在陕西3个地区的风险性分析结果，提出了防止枣实蝇入侵陕西的检疫对策。

Potential Risk Analysis and Quarantine Countermeasures of Carpomya veusuviana in Shaanxi Province

The ber fruit fly,Carpomya vesuviana Costa,was one of the most important quarantine pests causing considerable economic losses of jujube plant in the world.In order to assess the potential risk level of C.vesuviana to different regions in Shaanxi Province and develop quarantine countermeasures,the potential risk level of this pest in the three geographic regions of Shaanxi Province were analyzed and assessed,in accordance with international pest risk analysis methods,which based on distribution of the jujube plant in these regions.The results showed that the risk（R） values of the pest in north of Shaanxi,Guanzhong Region,south of Shaanxi were 2.239,2.065 and 1.469,respectively.Therefore,the ber fruit fly was a highly dangerous pest in north of Shaanxi and Guanzhong region and a low dangerous pest in south of Shaanxi.In view of above results in three regions,the quarantine countermeasures were proposed to prevent introduction and spread of ber fruit fly in Shaanxi.
