摘要
椰子致死性黄化病是严重危害椰子的一类世界性病害,其病原致死性黄化植原体已被多个国家列为检疫性有害生物,我国尚未有该病菌分布的报道。为加强对该病的检疫,参照国内外有害生物风险分析方法,从有害生物的分布状况、潜在的经济和生态环境危害性、寄主植物的经济重要性、传播扩散的可能性以及风险管理的难易程度等方面对椰子致死性黄化植原体传入我国的风险性进行定性和定量分析。结果表明,椰子致死性黄化植原体的风险性R值为2.27,属于高度危险性入侵物种,并提出了防止其入侵的风险管理策略。
Lethal yellowing disease is a worldwide serious coconut disease,its pathogen is classified as a quarantine pest by many countries and is not reported in China.In order to strengthen the quarantine of this pest,qualitative and quantitative risk of coconut lethal yellowing phytoplasma imported into China was analyzed from the distribution of the pest,potential economic and ecological impact,economic importance of the host,possibility of the spread and complexity of the risk management based on the methods of pest risk analysis in the world.The results showed that the invasive risk value of coconut lethal yellowing phytoplasma was 2.27,which means this pest is a highly dangerous invasive species.Risk management strategies were also proposed in order to prevent the pathogen importing into China.
