Aedes albopictus, commonly known as the Asian tiger mosquito, has become one of the most invasive mosquito species. Over the last 5 decades, it has been introduced and established in various tropical and temperate regions worldwide. First reported in Europe in 1979 in Albania and later in Italy in 1990, the species is now established in 13 European Union (EU)/European Economic Area (EEA) countries and 337 regions (2023). In Portugal, Ae. albopictus was first detected in the Algarve and Penafiel regions in 2017, followed by Alentejo in 2022 and Lisbon in 2023. This mosquito species poses a significant public health risk as a vector for numerous pathogenic viruses, including dengue, Zika, and chikungunya.
Aedes albopictus collected in Lisbon in 2023 were analyzed using cytochrome c oxidase I (COX) gene sequencing to understand their genetic relationships.
Our data indicate that the Ae. albopictus mosquito populations detected in three locations in Lisbon in 2023 correspond to recent but distinct introduction events.
Although there has been no local transmission of Aedes-transmitted viruses in mainland Portugal to date, the spread of the mosquito and increased international travel increase the risk of Aedes-borne disease outbreaks. The ongoing spread of Ae. albopictus in the country and the confirmed multiple introductions in new locations raise awareness of the need to monitor mosquito vectors to control and prevent autochthonous Aedes-borne disease outbreaks.
白纹伊蚊，俗称亚洲虎蚊，已成为最具侵袭性的蚊子物种之一。在过去的 50 年里，它已被引入并在世界范围内的各种热带和温带地区建立了种群。该物种于 1979 年首次在欧洲的阿尔巴尼亚报告，随后于 1990 年在意大利有记录，现已在 13 个欧盟/欧洲经济区国家和 337 个地区（2023 年）建立了种群。在葡萄牙，白纹伊蚊于 2017 年首次在阿尔加维和佩纳菲尔地区被发现，随后于 2022 年在阿连特茹地区和 2023 年在里斯本地区被发现。这种蚊子作为多种致病病毒（包括登革热、寨卡和基孔肯雅热）的传播媒介，对公共卫生构成重大威胁。
对 2023 年在里斯本采集的白纹伊蚊进行细胞色素 c 氧化酶 I（COX）基因测序分析，以了解其遗传关系。
我们的数据表明，2023 年在里斯本三个地点检测到的白纹伊蚊种群对应于最近但不同的引入事件。
尽管到目前为止，葡萄牙本土尚未发生蚊媒传播的病毒本地传播，但蚊子的传播和增加的国际旅行增加了蚊媒疾病爆发的风险。白纹伊蚊在该国的持续传播以及在新地点确认的多次引入引起了人们对监测蚊子媒介以控制和预防本地蚊媒疾病爆发的必要性的关注。
