摘要
为评估原产于南美洲的世界性毁灭害虫——番茄潜麦蛾Tuta absoluta(Meyrick)入侵我国的可能性和风险,应用有害生物风险分析方法对其进行风险评估,即对番茄潜麦蛾的不同入侵阶段风险进行定性分析,并应用多指标综合评价方法,从其国内外的发生现状、潜在的经济危害性、受害作物的经济重要性、入侵我国的可能性以及风险管理的难度等方面进行入侵风险的半定量分析。结果表明,番茄潜麦蛾虽然目前在我国还没有分布,但在我国大部分番茄产区都可以存活和定殖,是一种具有高度潜在威胁的有害生物;其入侵我国的风险评估值R为2.64,属于极高风险性农业有害生物。故此建议将其增补列入《中华人民共和国进境植物检疫性有害生物名录》,在新疆、云南、广西等边境省区开展预防性监测,并加强对该种害虫的检验检疫力度,严防其传入我国。
In order to evaluate the potential risk of invasion of the tomato leafminer Tuta absoluta (Meyrick), native to South America, into China, qualitative analysis of possible risk during different invasion stages and semi-quantitative analysis of the whole invasion were performed in this study. Semi-quantitative assessment included the present occurrence in the world, potential economic harm, and the economic importance of the damaged host plants, as well as the possibility of invasion into China and the difficulty of risk management. The results showed that T. absoluta could survive in and colonize most tomato-producing areas of China mainland although it is not distributed in China at present;the risk assessment value of its invasion into China was 2.64, and it was classified as an agricultural pest with very high risk. Therefore, it is suggested that it be added to the List of Quarantine Pests in Imported Plants of the People's Republic of China, for preventive monitoring in border provinces or autonomous regions such as Xinjiang, Yunnan and Guangxi, to strengthen the inspection and quarantine of this pest so as to strictly prevent its introduction into China.
