青梅山天牛的风险评估及防控策略

Risk analysis and control strategies of Massicus venustus Pascoe in Hainan Province

【目的】青皮为国家Ⅱ级保护植物,海南青皮林省级自然保护区是世界上仅存面积最大的2片滨海青皮林之一,2020年发现保护区内青梅山天牛严重危害青皮,为此有必要对该虫进行风险分析并确定风险等级。【方法】采用有害生物风险分析程序和方法,从分布情况、潜在经济危害性、受害寄主的经济重要性、传入的可能性、风险管理等5个方面,对青梅山天牛对海南省青皮林的风险性进行定性和定量综合评估。【结果】青梅山天牛的风险综合评估值(R)为2.05,属高度危险有害生物。【结论】青梅山天牛已经对海南青皮林保护区的青皮造成了严重影响,需从检疫管理、防控技术研发、生物生态学基础研究等方面对青梅山天牛进行风险管理。

【Aim】 Vatica mangachapoi is the national Ⅱ class protected plant.Hainan V.mangachapoi forest nature reserve is one of the two largest coastal V.mangachapoi forest in the world.In 2020,it was found that Massicus venustus seriously endangered V.mangachapoi in the reserve.Therefore,it is necessary to analyze the risk level of M.venustus to V.mangachapoi in Hainan.【Method】 The risk of M.venustus to V.mangachapoi in Hainan Province was evaluated qualitatively and quantitatively using pest risk analysis procedures and methods on five aspects,including distribution,potential economic hazard,the economic importance of the host,possibility of colonization,and risk management.【Result】 R-value of risk index evaluation system of M.venustus was 2.05,indicating that it was a high dangerous pest.【Conclusion】 M.venustus severely impacts V.mangachapoi in the nature reserve.It is necessary to conduct risk management on M.venustus from the aspects of quarantine management,prevention,control technology research,and basic research of bio-ecology.
