In Europe, Aedes albopictus is an important vector of chikungunya virus and Dirofilaria nematodes and has been involved in local autochthonous circulation of dengue and Zika viruses. Due to the ongoing spread, targeted field surveillance at potential points of entry of invasive Aedes mosquitoes was initiated by the Republic of Moldova in 2020 as part of the transboundary "Invasive Aedes Mosquitoes COST-Action project."
In 2020, ovitraps were positioned at each of three locations: the border crossing to Romania in Leuşeni (Hancesti region), Chişinӑu International Airport and Chişinӑu Botanical Garden.
A total of 188 Aedes spp. eggs were collected at the Chişinӑu International Airport between August and September 2020. Twenty-three adults reared in the laboratory were identified morphologically as Ae. albopictus (Skuse, 1895), and 12 selected specimens were confirmed by molecular barcoding of the cytochrome oxidase subunit I gene region. In addition, one adult Ae. albopictus female at the same site was caught with a manual aspirator.
This is the first documented report of Ae. albopictus in the Republic of Moldova. The presence of immature and adult stages indicates the local reproduction of the species in the country. Therefore, it is crucial to extend and strengthen surveillance of the invasive Aedes mosquitoes to prevent Ae. albopictus and other exotic mosquito species from becoming established in the Republic of Moldova.
在欧洲，白纹伊蚊是基孔肯雅病毒和犬心丝虫的重要载体，并且已参与登革热和寨卡病毒的本地自生循环。由于持续传播，摩尔多瓦共和国于 2020 年作为跨境“入侵白纹伊蚊合作行动”项目的一部分，启动了针对入侵白纹伊蚊潜在入境点的有针对性的实地监测。
2020 年，在勒什涅（汉切什地区）与罗马尼亚的过境点、基希讷乌国际机场和基希讷乌植物园的每个地点都放置了诱卵器。
2020 年 8 月至 9 月期间，在基希讷乌国际机场共收集到 188 只白纹伊蚊卵。在实验室中饲养的 23 只成虫经形态学鉴定为白纹伊蚊（Skuse，1895），并通过细胞色素氧化酶亚基 I 基因区域的分子条码确认了 12 个选定标本。此外，在同一地点还通过手动吸蚊器捕获了一只成年雌性白纹伊蚊。
这是摩尔多瓦共和国首次记录到白纹伊蚊。幼体和成虫的存在表明该物种在该国的本地繁殖。因此，必须扩大和加强对入侵白纹伊蚊的监测，以防止白纹伊蚊和其他外来蚊种在摩尔多瓦共和国立足。
