[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.
