摘要: 目的 利用形态学与分子生物学的方法对中山港口岸进口集装箱中截获的2只蜚蠊进行种类鉴定。方法 2021年11月在中山港口岸来自尼日利亚的集装箱截获了1只雌性蜚蠊和1只蜚蠊若虫,通过形态学方法检索雌性蜚蠊的形态特征,并同时提取2只蜚蠊基因组DNA,用线粒体细胞色素C氧化酶亚基Ⅰ(COⅠ)的基因片段进行PCR扩增和测序,测序结果在GenBank中进行比对,采用邻接法构建系统进化树。结果 雌性蜚蠊形态鉴定为小异甲蠊,2只蜚蠊的COⅠ基因序列在GenBank中未比对出相似度>98%的同源物种,但是2只蜚蠊COⅠ基因序列相互比对相似度>98%,可判定该蜚蠊若虫与雌性成虫同为小异甲蠊(Diplopterina parva)。经查证国内未见该种蜚蠊分布。结论 中山港口岸进口集装箱截获的2只蜚蠊通过形态学和分子生物学的方法鉴定均为小异甲蠊,为国内未见分布种。

Abstract: Objective To identify the species of two cockroaches intercepted in the import containers at Zhongshan port in China by morphological and molecular methods. Methods A female cockroach and a cockroach nymph were intercepted in the imported containers from Nigeria at Zhongshan port in November, 2021. The morphological characteristics of the female cockroach were retrieved by the morphological method, and the genomic DNA was extracted from the two cockroaches. The gene segment of mitochondrial cytochrome c oxidase subunit Ⅰ (COⅠ) was amplified by polymerase chain reaction and sequenced, and the sequencing results were compared in GenBank. The phylogenetic tree was constructed by neighbor-joining method. Results The female cockroach was morphologically identified as Diplopterina parva. The COⅠ gene sequences of the two cockroaches did not compare the homologous species with a similarity of more than 98% in GenBank, but the similarity of the COⅠ gene sequences of the two cockroaches was >98%. The cockroach nymph was identified as D. parva. It has been verified that no distribution of this species has been seen in China. Conclusion The two cockroaches intercepted in the imported containers at Zhongshan port are identified as D. parva by morphological and molecular methods, which is a non-recorded species in China.
