摘要: 为准确鉴定采自安徽省太湖县天花镇的实蝇幼虫,随机选取5头实蝇幼虫作为样本材料,运用DNA条形码技术和PCR技术对其进行分子鉴定。结果表明,实蝇幼虫样本的DNA条形码序列与BOLD数据库中柑橘大实蝇(Bactrocera minax)标准序列的相似性均为100%;使用MAGA-X软件构建系统进化树,实蝇幼虫样本序列与NCBI数据库中的柑橘大实蝇序列形成一个单系,且与其近缘物种明显区分开;使用柑橘大实蝇特异引物进行PCR,产物长度符合特异引物扩增序列长度特征,表明5头实蝇幼虫样本为柑橘大实蝇。

Abstract: In order to accurately identify the fruit fly larvae collected from Tianhua Town, Taihu Lake County, Anhui Province, five fruit fly larvae were randomly selected as sample materials, and their molecular identification was carried out using DNA barcode technology and PCR technology. The results showed that the DNA bar code sequence of the fruit fly larva sample was 100% similar to the standard sequence of Bactrocera minax in BOLD database; the phylogenetic tree was constructed using the MAGA-X software. The sample sequence of fruit fly larvae and the Bactrocera minax sequence in the NCBI database formed a single line, which was clearly distinguished from its related species; PCR was carried out with specific primers of citrus fruit fly, and the length of the product was consistent with the characteristics of the amplified sequence length of the specific primers, indicating that the five samples of fruit fly larvae were Bactrocera minax.
