Aedes albopictus, known as the Asian tiger mosquito, is an extensively studied mosquito species recognized for its rapid global expansion and its capacity to transmit a range of viruses such as dengue, chikungunya, Zika, and yellow fever viruses. In 2010, Ae. albopictus was observed for the first time in Tizi-Ouzou, Algeria, and since then has colonized all the northern part of the country until the semi-arid areas. The present study was devoted to the molecular characterization of Ae. albopictus in Algeria.
A total of 20 selected mosquitos,originated from collected eggs in five different districts of northern Algeria weretested by PCR amplification and sequencing of the Cytochrome c oxidase subunit 1 a (COIa).
Pairwise alignment of the obtained sequences with representative Ae. albopictus available COIasequences of the world exhibit 117 different haplotypes. The Algerian sequences are grouped in 1 haplotype shared with Morroco, Madagascar and Mauritius in Africa and 3 other continents (Asia, Europe and America). Asia expresses the highest genetic and nucleotidic diversity (Hd = 0.828;π = 0.0144). In China two new species not described in the literature and confused with Ae. albopictus are detected.
These results could be used as preliminary data to study and develop targeted control strategies to prevent this vector from spreading in Algeria.
白纹伊蚊，即亚洲虎蚊，是一种经过广泛研究的蚊虫物种，因其在全球范围内的迅速扩张以及传播一系列病毒（如登革热、基孔肯雅热、寨卡病毒和黄热病病毒）的能力而闻名。2010年，在阿尔及利亚的提济乌祖首次发现了白纹伊蚊，自那时起，它已在该国北部直至半干旱地区定殖。本研究致力于对阿尔及利亚的白纹伊蚊进行分子特征分析。
总共20只经过挑选的蚊子，源自阿尔及利亚北部五个不同地区采集的卵，通过细胞色素c氧化酶亚基1a（COIa）的PCR扩增和测序进行检测。
将获得的序列与世界范围内具有代表性的白纹伊蚊可用COI序列进行成对比对，发现有117种不同的单倍型。阿尔及利亚的序列被归为1个单倍型，与非洲的摩洛哥、马达加斯加和毛里求斯以及其他三大洲（亚洲、欧洲和美洲）共享。亚洲表现出最高的遗传和核苷酸多样性（Hd = 0.828；π = 0.0144）。在中国检测到两种文献中未描述且易与白纹伊蚊混淆的新物种。
这些结果可作为初步数据，用于研究和制定有针对性的控制策略，以防止这种病媒在阿尔及利亚传播。
