马铃薯甲虫入侵云南省的风险性分析及管理对策

Pest risk analysis and risk management of invasion of Colorado Potato Beetle in Yunnan

马铃薯甲虫(Leptinotarsa decemlineata(Say))是马铃薯的一种毁灭性害虫,扩散迅速,防控困难,已被许多国家列为检疫对象。云南是我国马铃薯的主要产区,目前云南省马铃薯种植区尚未发现该虫的发生与危害。为探明马铃薯甲虫在云南省的风险性,本文依据国际有害生物风险分析原则,以云南省的气候、马铃薯种植情况及马铃薯甲虫的生物学特性为基础,利用外来入侵有害生物多指标综合评价体系,对马铃薯甲虫入侵云南的风险性进行了分析。结果表明,马铃薯甲虫入侵云南的风险值为2.24,属于高度风险类型。同时,根据马铃薯甲虫较高的入侵云南的潜在风险,本文还提出了对马铃薯甲虫入侵风险管理的对策。

The Colorado potato beetle （CPB）, Leptinotarsa decemlineata, is one of the most pest causing serious damage of potato industries in the world, it spreads rapidly and it is very difficult to control,the pest has been listed as an important quarantine pest in many countries. Yunnan is the most important potato industry areas in China, no CPB had been found in Yunnan up to now. The risk of Colorado Potato Beetle in Yunnan province was comprehensively evaluated in view of qualitative analysis and quantitative evaluation using comprehensive evaluation index system for invasive alien pests according to the potato planting, weather condition and biology of Colorado Potato Beetle, based on the principles of pest risk analysis（PRA） from comprehensive evaluation index system.Results showed that Colorado Potato Beetle had suitable hosts with a large area,high vitality and it could cause serious economic losses on potato in Yunnan,and the risk assessment value（R） was 2.24. In conclusion, Colorado Potato Beetle belonged to the most dangerous invasive alien pest to Yunnan. The risk management strategies were proposed to for preventing the introduction and the spread of it in potato planting areas in Yunnan province.
