摘　　要：【目的】桑白盾蚧作为食性杂、寄主广、繁殖力强的一种盾蚧,通过开展该虫在我国的危害风险综合评价,以期为该有害生物的防控提供技术支持。【方法】依据有害生物风险分析(PRA)程序,运用多指标综合评价体系,对桑白盾蚧在我国的危害风险进行定性与定量评估。【结果】根据入侵、定殖、扩散、寄主经济影响及防控难度5项指标评估,桑白盾蚧综合风险值达2.18(>2.0高危阈值),符合国际植检高危有害生物标准(ISPM No.11),其跨境传播潜力与防控复杂性构成显著生物安全威胁。【结论】桑白盾蚧虽在我国已有分布记录,但仍需采取严格的检疫管理措施以防止其危害风险进一步扩大。[Objective]Pseudaulacaspis pentagona is known as one of the omnivorous Diaspididae with wide-range of hosts and strong reproductive capacity.This study conducted a comprehensive risk evaluation on the aforementioned pest and attempted to provide technical support for the prevention of Pseudaulacaspis pentagona.[Method]According to the pest risk analysis procedure(RPA),the multi-indicator assessment system was used to qualitatively and quantitatively summarize the risk level of Pseudaulacaspis pentagona.[Result]The assessment system took the introduced possibility,dispersal possibility,economic importance of infected host and management difficulty into consideration,the integrated risk value of Pseudaulacaspis pentagona was assigned as 2.18.Thus,this pest was classified as high-risk pest.[Conclusion]The result indicated that despite of the existing occurrence of Pseudaulacaspis pentagona in China,subsequent quarantine measures should be strictly conducted to avoid the aggravation of current risk level.
