摘　　要：目的利用DNA条形码技术鉴定外来媒介生物,提高物种鉴定的速度与准确度。方法对2013年9月在中山神湾口岸截获来自澳大利亚的丽蝇进行形态与DNA条形码鉴定,通过与澳大利亚的蝇类专家进行标本交流,进一步确认鉴定结果;并与相似种螳丽蝇进行形态与DNA条形码上的比较。结果通过形态观察与DNA条形码鉴定,所截获的丽蝇为杜比亚丽蝇;经科技查新,确认为中国未见分布种。结论 DNA条形码是传统形态分类的有力补充,对在国境卫生检验检疫工作中及时鉴定媒介生物,减少媒介生物本身及其携带病原体的扩散,减少对公共卫生的安全威胁起到重要作用。Objective To apply DNA barcoding in species identification of exotic vectors. Methods Morphology and DNA barcoding based identification was performed on two blowflies from Australia that were intercepted at the Shenwan port （Zhongshan, Guangdong） in September 2013. The identification results were confirmed with specialists in Australia and compared to data of a similar species, Calliphora augur. Results The two blowflies were identified as C. dubia, which represents exotic species in China based on sci-teeh novelty search. Conclusion DNA barcoding is a strong supplementary tool for conventional taxonomy, which plays an important role in frontier health and quarantine inspection by timely identifying vector insects, reducing the spread of vector insects and the carried pathogens, and mitigating threats to public health.
