摘　　要：【目的】2022年先后在海南省万宁市兴隆镇的番石榴、琼中黎族苗族自治县黎母山蒲桃上发现1种蚧虫为害,对其进行报道,以期为该物种的检疫鉴定和监测防控工作提供参考。【方法】通过形态学方法,确定该蚧虫的种类;参阅国内外相关文献资料,梳理该蚧虫的基本信息及形态鉴别特征,并参照国内外有害生物风险性分析指标体系进行风险性评价。【结果】经鉴定该蚧虫为检疫性害虫七角星蜡蚧,在海南省首次发现,为外来入侵害虫,危害多种果树及观赏性植物。本研究介绍了七角星蜡蚧的分类地位、分布与寄主、形态特征、生物学和危害等;编制了中国蜡蚧属物种的检索表;七角星蜡蚧的综合风险值为1.72。【结论】七角星蜡蚧在我国属于中风险有害外来入侵生物,在我国热带地区扩散趋势明显,应加以警惕,加强其调查监测和检疫工作,以防其进一步扩散。【Aim】In 2022,a harmful scale insect was found on Psidium guajava in Xinglong Town,Wanning City,Hainan Province,and on Syzygium jambos in Limu Mountain,Qiongzhong Li and Miao Autonomous County.Herein,we report details of this pest to provide a reference for its quarantine identification,monitoring,and control.【Method】The identity of this scale insect was determined based on morphological observations.In this regard,we surveyed the relevant domestic and international literature,and reviewed the basic information and morphological identification characteristics of this scale insect.In addition,we performed a risk assessment based on the risk assessment index system of China for this pest.【Result】This insect was identified as the quarantine pest Ceroplastes stellifer,which is an invasive alien pest that has caused extensive damage of a wide range in fruit trees and ornamental plants.This is the first time that a risk-invasive pest has been found in Hainan Province.In this study,we provide details of the taxonomic status,distribution,hosts,morphological characteristics,and biology and hazards of C.stellifer.We also compiled a key to the species of Ceroplastes in China and determined a comprehensive risk value(R)of 1.72 for C.stellifer.【Conclusion】C.stellifer is a moderately destructive alien invasive pest in China,the spread of which is evident in the tropical areas of the country.Accordingly,heightened levels of vigilance,along with a strengthening of investigation,monitoring,and quarantine measures,are necessary in these areas to prevent the further spread of this pest.
