红火蚁在云南的入侵风险分析

背景]红火蚁是一种严重威胁公共设施、动植物和人类安全的重要害虫，在国际上被列为极具破坏性和攻击性的入侵生物之一。自2004年在我国大陆广东省首次发现以来，其发生范围急剧扩大，目前已扩散至南方多个省份。方法]通过分析该虫进入、定殖和扩散的可能性、危害影响和危害管理难度等5个方面，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，对红火蚁在云南的入侵风险进行评估。结果]通过定性和定量风险分析，对其入侵云南的风险做出综合评价，得出风险评估值R=2．25。结论与意义]红火蚁在云南属高度风险的有害生物，需在云南各口岸进境检疫中实施相应的风险管理，分析结果可为云南省开展红火蚁的检疫防控提供参考。

Invasive risk analysis of Solenopsis invicta Buren using integrated multi-index evaluation system in Yunnan Province

Background ] The red imported fire ant, Solenopsis invicta Buren, is a significant pest that seriously threatens plants and animals, and humans. It was listed as one of the most destructive and aggressive invasive alien species in the world. Since its first appearance in Guangdong Province of mainland China in 2004, it has spread rapidly to other regions. Method] In accordance with the guidelines for pest risk analysis of the International Standards for Phytosanitary Measures （ISPM） of FAO, an integrated multi- index evaluation system was performed in the Yunnan Province. It examined five aspects of invasion risk ： possibility of introduction, establishment and diffusion, harmful influence and hazard management. Result] The risk assessment value for red imported fire ant in Yunnan Province was 2.25. Conclusion and significance] Red imported fire ants belong to high risk of harmful pest, and it is es- sential to implement the corresponding risk management and quarantine in the entry port of Yunnan Province.
