椰子叶螨Aceria(Eriophyes)guerreronis对我国椰子产业的风险性分析

【目的】明确刺吸式害虫椰子叶螨对我国椰子产业的风险,为该虫的检验检疫和应急防控提供参考。【方法】从椰子叶螨的国内外发生现状、潜在危害性、受害作物的经济重要性、定殖扩散的可能性以及风险管理的难度等方面,对椰子叶螨危害我国椰子产业的风险性进行定性和定量评估。【结果】椰子叶螨个体较小、传播方式多样、检疫和灭除难度较大,根据有害生物风险评估体系及多指标综合评估方法统计,该虫风险值评价指标体系R值为1.80,结合我国外来物种风险等级划分标准,属于中度危险有害生物。【结论】椰子叶螨在我国属于中度危险有害生物,对我国椰子产业具有较高的风险,需从检疫管理、检测及防控技术引进与研发等方面制定针对椰子叶螨的风险管理措施。

Risk analysis of Aceria (Eriophyes) guerreronis on coconut industry in China

Aim] The objective was to clarify the risk of Aceria (Eriophyes) guerreronis on coconut industry in China, and provide the reference for its quarantine and emergency prevention and control.Method] The qualitative and quantitative assessment of A. guerreronis to coconut industry of our country was discussed through current outbreak situation, potential economic damage, host economic importance, the possibility of colonization and diffusion and the difficulty of risk management.Result] Invasive analysis results indicated that A. guerreronis is small pest with diversity transmission methods, and difficult for quarantine and eradication. Based on risk assessment system of harmful organisms and multi-index comprehensive evaluation method, R value of A. guerreronis invasive risk is 1.80. According to the risk classification standard of alien species in China, A. guerreronis belongs to the moderately dangerous pests.Conclusion] Due to its risk to the coconut industry in China, it is necessary to develop risk management measures against it, in terms of quarantine management, detection, prevention and control technology introduction and research and development.
