大家白蚁在云南的入侵风险分析

Invasive Risk Analysis of Coptotermes curvignathus in Yunnan Using Integrated Multi-index Evaluation System

大家白蚁(Coptotermes curvignathus)是东南亚地区可危害多种林木的一种重要害虫,依据国际植物检疫措施标准(ISPM)中的有害生物风险分析原则,利用云南外来入侵有害生物多指标综合评价体系,对大家白蚁在云南的入侵风险进行评估。结果表明,大家白蚁在云南的入侵风险指标值R为2.32,属于高度风险的有害生物,有必要在云南口岸进境检疫中实施相应的风险管理。

Coptotermes curvignathus is one of the serious insect pests in Southeast Asia. The risk possessed by C. curvignathus in Yunna province, China was assessed using the integrated multi-index evaluation system, based on pest risk assessment scheme （PRAS） of international standards for pest measurements （ISPM）. All aspects related to C. curvignathus in the likelihood of entry, establishment and spreading, and influence and risk management in the epidemic area were taken into consideration of the assessment. Results showed that the integrated evaluation index R was valued as 2.32. It is highlighted that C. curvignathus possesses the significant risk to entry, establish and spread in Yunnan.
