摘　　要：【目的】明确北京口岸从进境邮寄物中截获的蜗牛种类,及其分类地位、分布、潜在入侵危害性等情况。【方法】通过形态学特征和DNA条形码技术对截获的蜗牛样本进行物种鉴定,并通过相关文献综合分析比较该物种与近似种的区别,以及我国口岸检疫性蜗牛的截获情况。【结果】鉴定结果为检疫性软体动物盖罩大蜗牛,隶属于腹足纲柄眼目大蜗牛科大蜗牛属。【结论】针对随邮寄物传入的检疫性蜗牛种类,建议口岸在主要应用形态学进行鉴定的基础上,利用DNA条形码技术进行辅助鉴定,从而提高鉴定准确率。【Aim】To clarify the species,classification status,distribution and potential invasion harmfulness of the snail intercepted in mail from Poland at Beijing port.【Method】Both morphological characteristics and DNA barcoding were used to compare and identify the intercepted sample.The morphological characteristics of Helix pomatia were introduced,and also the similar species.The intercept situation quarantine snail in China is discussed.【Result】The snail is identified as the quarantine pest,Helix pomatia Linnaeus,1758,which belongs to class Gastropoda,order Stylommatophora,family Helicidae.【Conclusion】The quarantine pests in mail should be paid attention by the customs departments.Our results suggested that the DNA barcoding method is effective in assisting species identification in quarantine routine.
