The invasive mosquito is regarded as a public health threat due to its ability to transmit pathogens such as dengue and chikungunya viruses, its wide range of hosts, and its ecological plasticity. has already invaded parts of the Middle East region and further expansion is expected. Twenty-two sites in three districts of Yemen (Al Ghaydha, Hawf, and Sayhout) were screened for the presence of mosquitoes. We surveyed water bodies and containers, and deployed Centers for Disease Control and Prevention (CDC) and Biogents Sentinel (BG) traps, spray catches, and aspiration for adult collection. was recorded for the first time in Yemen in September 2023, during routine surveillance in Al Mahrah Governorate. Adults and immature stages of were identified in Hawf, a city 17 m above sea level in the easternmost part of the Governorate of Al Mahrah, which is located less than 8 km from the border with Oman. Our findings showed that adults were coexisting with both and in the same location and occupying the same containers with with a ratio of 1:2. This is the first report on the presence of in Yemen. The proximity, ongoing human activity and transportation exchanges between Al Mahrah and Oman may have played a role in the introduction of this species. Intensive efforts should be undertaken to monitor and manage spread in the country, in addition to coordinating cross-border surveillance with Oman. The presence of both spp. vectors together highlights the need for surveillance for associated diseases and consideration of countermeasures.
这种入侵性蚊子因其传播登革热和基孔肯雅病毒等病原体的能力、广泛的宿主范围以及生态可塑性，被视为对公共卫生的威胁。它已经入侵了中东地区的部分地区，预计还会进一步扩散。在也门三个地区（盖伊达、豪夫和赛胡特）的22个地点对蚊子的存在情况进行了筛查。我们调查了水体和容器，并部署了疾病控制与预防中心（CDC）诱捕器、Biogents Sentinel（BG）诱捕器、喷雾捕捉法以及用于成虫采集的吸虫法。2023年9月，在马哈拉省的例行监测期间，首次在也门记录到这种蚊子。在海拔17米的豪夫发现了该蚊子的成虫和未成熟阶段，豪夫位于马哈拉省最东部，距离与阿曼的边境不到8公里。我们的研究结果表明，该蚊子的成虫与另两种蚊子在同一地点共存，并与另一种蚊子占据相同的容器，比例为1:2。这是也门存在这种蚊子的首次报告。马哈拉与阿曼之间的接近程度、持续的人类活动和交通往来可能在该物种的引入中起到了作用。除了与阿曼协调跨境监测外，还应大力开展监测和管理工作，以控制该国这种蚊子的传播。两种病媒蚊子的同时存在凸显了对相关疾病进行监测和考虑应对措施的必要性。
