Ceroplastes rusci (Linnaeus) is a quarantine pest for import plants in China. In March 2023, an outbreak of C. rusci in an Areca catechu (a species of palm) plantation in Nanbin farm, Sanya City, was studied, which was the first discovery of this insect in Hainan Province. To elucidate the risk analysis level of this insect in Hainan, qualitative and semi-quantitative analysis methods were performed to understand the risk of C. rusci in Hainan. The results indicated that the R-value of C. rusci in Hainan is 2.56, classifying it as a particularly harmful pest. Based on the analysis results, active prevention and monitoring and early warning systems should be implemented promptly, and emergency plans for prevention and control should be formulated and initiated. Based on the risk analysis criteria of forestry pests and the risk analysis results of C. rusci in Hainan, suitable risk management measures have been determined.
