摘　　要：马铃薯甲虫(Leptinotarsa decemlineata Say)又称科罗拉多马铃薯甲虫,是国际上公认的毁灭性检疫害虫之一,给世界马铃薯产业造成了重大损失。目前陕西尚未发现该甲虫。为了评估马铃薯甲虫在陕西省的潜在危险性,以制定科学的检疫对策。参照国际上有害生物风险分析方法,结合其最适宜寄主分布及其分布区的气象数据,对马铃薯甲虫在陕西省的3个地理区域进行了综合分析评价。结果表明:马铃薯甲虫在陕北、关中和陕南的评估风险性R值分别为2.331、2.051和2.149。马铃薯甲虫在陕西全境属于高度危险性害虫,鉴于马铃薯甲虫在陕西省的高度风险性,提出了防止马铃薯甲虫入侵陕西的检疫对策。The Colorado potato beetle （CPB）, Leptinotarsa decemlineata, was one of the most important quarantine pest causing considerable economic losses of potato industries in the world. The pest has not detected in Shaanxi Province at present. The objective of this study is to assess the potential risk analysis （PRA） of L. decemlineata to different regions and develop quarantine countermeasures in Shaanxi Province. In according with international pest risk analysis methods, the PRA of this pest in the three geographic regions of Shaanxi Province was analyzed and assessed, which based on distribution of the tomato plant and meteorological data in these regions. The results showed that, the risk （R） values of the pest in north of Shaanxi, Guanzhong Region, south of Shaanxi were 2.331, 2.051 and 2.149, respectively. In conclusion, the Colorado potato beetle was a highly dangerous pest in Shaanxi Province. The quarantine countermeasures were proposed to prevent introduction and spread invading of the beetle in Shaanxi in view of above results.
