摘要: 枣实蝇(Carpomya vesuviana Costa)是一种新入侵检疫性有害生物。应用PCR-RFLP技术,快速区分鉴定了枣实蝇与我国口岸截获频率较高的5种检疫性实蝇。研究表明:设计出的2对引物对6种供试实蝇线粒体DNA(mtDNA)进行PCR扩增,其扩增片断大小分别为350 bp和450 bp。PCR扩增产物用2种限制性内切酶Dra I和MseI进行酶切,根据不同的酶切位点准确区分了6种供试的实蝇。此方法可用于口岸截获实蝇的快速检疫鉴定。

Abstract: Carpomya vesuviana Costa has been a new quarantine pest in China. In this paper, the method of rapid identification of C. vesuviana Costa and 5 relative species of fruit flies was studied based on PCR-RFLP of the mitochondrial DNA(mtDNA). The results showed that DNAs, which were estimated about 350 bp and 450 bp respectively, were obtained by means of PCR with two pairs of primers designed from mtDNA of target pests.The PCR-products could be registered by restriction enzymes(Dra I and Mse I). All the 6 species could be discriminated according to the banding patterns of the restriction enzymes. It is suggested that the method is reliable for quick discrimination of fruit flies.
