ABSTRACT Aedes albopictus (Skuse) (Diptera: Culicidae), the Asian tiger mosquito indigenous to Asia, now an invasive species worldwide, is an important vector for several arboviruses. Genetic analysis using the mitochondrial nicotinamide adenine dinucleotide dehydrogenase subunit 5 (ND5) gene was carried out in populations from Cameroon (n = 50), Hawaii (n = 38), Italy (n = 20), the continental United States, Brazil, and its native range. Data for Brazil, the continental United States, and the native range was obtained from Birungi and Munstermann (2002). Direct sequencing was used to identity unique haplotypes. The limited phylogeographic partitioning of haplotypes with low levels of sequence divergence in both Cameroon and Hawaii was consistent with the population structure of Ae. albopictus in the United States and Brazil. Four new haplotypes were identified from the samples from Cameroon and Hawaii, adding to previously described haplotypes. Hawaii shared a haplotype with Cameroon that was unique to these two regions. Hawaii also had higher overall haplotype diversity than seen in previous continental United States, Brazil, or native range populations. Hawaiian, Cameroon, and Italian populations did not share haplotypes with Brazil, which validates the earlier mitochondrial DNA studies indicating a separate introduction of this species into Brazil.

使用线粒体烟酰胺腺嘌呤二核苷酸脱氢酶亚基 5 序列对白纹伊蚊（双翅目：蚊科）入侵种群进行种群遗传学研究

摘要 白纹伊蚊（Skuse）（双翅目：蚊科）是原产于亚洲的亚洲虎蚊，现已成为世界范围内的入侵物种，是多种虫媒病毒的重要载体。使用线粒体烟酰胺腺嘌呤二核苷酸脱氢酶亚基 5 (ND5) 基因对来自喀麦隆 (n = 50)、夏威夷 (n = 38)、意大利 (n = 20)、美国大陆、巴西和日本的人群进行了遗传分析。它的原生范围。巴西、美国大陆和本土分布区的数据来自 Birungi 和 Munstermann (2002)。直接测序用于鉴定独特的单倍型。喀麦隆和夏威夷的序列差异水平较低的单倍型的系统发育地理学划分有限，与伊蚊的种群结构一致。白纹伊蚊分布于美国和巴西。从喀麦隆和夏威夷的样本中鉴定出四种新的单倍型，增加了之前描述的单倍型。夏威夷与喀麦隆共享一个单倍型，这是这两个地区独有的。夏威夷的整体单倍型多样性也高于以前的美国大陆、巴西或本土种群。夏威夷、喀麦隆和意大利种群与巴西没有相同的单倍型，这验证了早期的线粒体 DNA 研究表明该物种是单独引入巴西的。
