Abstract

Background: The Asian tiger mosquito, Aedes albopictus (Skuse, 1894), is a highly invasive species that has successfully colonized many tropical and temperate regions worldwide. Its rapid global spread is strongly associated with human activities and has created favorable conditions for the emergence of human arboviruses in new geographic areas.

Methods: Mosquito larvae were collected by community health workers from different breeding sites and reared to adults in a field insectary. Adult mosquitoes were morphologically identified to species level. Species identification was confirmed by cytochrome oxidase subunit I DNA barcoding.

Results: We report the first detection of Aedes albopictus in Angola during an Anopheles stephensi survey conducted in Soyo, Zaire Province. Phylogenetic analysis indicated that the Angolan Ae. albopictus population clusters with sequences from Central African countries, suggesting an introduction from within the continent.

Conclusions: The presence of Ae. albopictus in Angola highlights the need for enhanced vector surveillance and control measures to prevent the emergence of arboviral diseases. This finding emphasizes the relevance of collaboration between local health authorities, communities, and international organizations in monitoring the spread of invasive mosquito species.

索约产油市的亚洲虎蚊：安哥拉首次报告白纹伊蚊（Skuse, 1894）。

背景：亚洲虎蚊白纹伊蚊（Aedes albopictus, Skuse, 1894）是一种高度入侵物种，已成功地在全球许多热带和温带地区定居。它在全球的迅速传播与人类活动密切相关，并为在新的地理区域出现人类虫媒病毒创造了有利条件。方法：由社区卫生工作者在不同孳生地点采集蚊幼虫，在野外生境中饲养成蚊。成蚊形态鉴定达到种级。通过细胞色素氧化酶I亚基DNA条形码鉴定。结果：我们报告在扎伊尔省索约进行的一项斯氏按蚊调查中首次在安哥拉发现白纹伊蚊。系统发育分析表明，安哥拉伊蚊属。白纹伊蚊种群聚集序列来自中非国家，提示来自非洲大陆内部。结论：白纹伊蚊的存在；安哥拉白纹伊蚊疫情突出表明，需要加强媒介监测和控制措施，以防止虫媒病毒性疾病的出现。这一发现强调了地方卫生当局、社区和国际组织在监测入侵性蚊子物种传播方面开展合作的相关性。

期刊介绍： Parasites & Vectors is an open access, peer-reviewed online journal dealing with the biology of parasites, parasitic diseases, intermediate hosts, vectors and vector-borne pathogens. Manuscripts published in this journal will be available to all worldwide, with no barriers to access, immediately following acceptance. However, authors retain the copyright of their material and may use it, or distribute it, as they wish. Manuscripts on all aspects of the basic and applied biology of parasites, intermediate hosts, vectors and vector-borne pathogens will be considered. In addition to the traditional and well-established areas of science in these fields, we also aim to provide a vehicle for publication of the rapidly developing resources and technology in parasite, intermediate host and vector genomics and their impacts on biological research. We are able to publish large datasets and extensive results, frequently associated with genomic and post-genomic technologies, which are not readily accommodated in traditional journals. Manuscripts addressing broader issues, for example economics, social sciences and global climate change in relation to parasites, vectors and disease control, are also welcomed.
