2022年1月,我们收到来自广东省汕头市的3巢蚂蚁标本,经形态特征和分子鉴定确定为小火蚁。小火蚁被世界自然保护联盟(IUCN)列为最具危害性的100种入侵物种之一,已从其原产地南美洲蔓延到除南极洲以外的每个大陆。对9头工蚁的线粒体基因序列(mtDNA COI)分析发现,它们与来自阿根廷的样本有着密切的遗传关系。本文首次正式记录了小火蚁入侵中国大陆,但它在中国的入侵阶段和发生程度尚不清楚,相关部门应该加强该种入侵蚂蚁的植物检疫、发生分布调查、生物生态学特性研究、监测与防控技术开发等,以积极应对小火蚁对我国社会与生态安全的威胁

Abstract  In January 2022, we received ant specimens collected from three field colonies from Shantou City, Guangdong Province, China.  They were identified as the little fire ant, Wasmannia auropunctata, through morphological and molecular analyses.  Wasmannia auropunctata is listed as one of the 100 most dangerous invasive species by the International Union for Conservation of Nature (IUCN) and has spread from its native range in South America to every continent except Antarctica.  DNA analysis of mitochondrial cytochrome c oxidase subunit I (COI) in nine specimens of W. auropunctata found that they had a close genetic relationship with specimens from Argentina.  This study represents the first formal record of the establishment of W. auropunctata outdoor in Chinese mainland.  However, the invasion stage and occurrence degree of W. auropunctata in China are not clear to date.  The implementation of quarantine measures, investigation of the occurrence and distribution, and development of monitoring and control strategies are needed to actively respond to the threat posed by this highly invasive ant.
