我国首次检出双色多刺蚁及多刺蚁属介绍

A first record of the ant species,Polyrhachis bicolor Smith,1858 and the introduction of Polyrhachis into China

【目的】2016年7月北京出入境检验检疫局从泰国进境商品山竹果中检出双色多刺蚁,经查询,该种为我国进出境检疫部门首次检出。了解多刺蚁属情况可为该类昆虫的检疫鉴定提供依据。【方法】笔者通过对双色多刺蚁及多刺蚁属相关文献进行翻译和整理,详细介绍了双色多刺蚁的分类地位、分布、形态特征及近似种,以及多刺蚁属在中国的种类,并简要分析了我国检疫系统对多刺蚁属的截获情况。【结果】双色多刺蚁(膜翅目:蚁科)主要分布于东南亚和澳大利亚地区,在我国仅分布于云南省。多刺蚁属在我国已知45种1亚种。2003—2016年7月我国检疫系统共检出多刺蚁属2097批次。【结论】多刺蚁属随货物包装携带入境的概率较高,各进出境检疫部门应加强对该类昆虫的检疫工作。

[Aim] In July 2016, a specimen of the ant Polyrhachis bicolor Smith, 1858 was collected and identified by the Plant Quarantine Lab of Beijing Entry-Exit Inspection and Quarantine Bureau, in a mangosteen shipment from Thailand. This is the first interception record for China. Understanding the situation of Polyrhachis can provide basis for the quarantine and identification of the insects.[Method] By collecting and translating references, we discribed the taxonomic status, distribution, morphologiacal characteristics and similar species of P. bicolor. The species of the genus Polyrhachis in China were introduced, and the intercept situation of the genus were analyzed.[Result] P. bicolor （Hymenoptera：Formicidae） distributed mainly in southeast Aisa and Austrilia, it distributed only in Yunnan Province in China. Forty-five species and 1 subspecies of Polyrhachis were known in China. A total of 2097 batches of Polyrhachis were found in the quarantine system from 2003 to July 2016.[Conclusion] Polyrhachis are most likely to invade by cargo container. The departments of entry and exit should strengthen quarantine work on the insects.
