is an invasive mosquito that has colonized several European countries as well as Portugal, where it was detected for the first time in 2017. To increase the knowledge of population dynamics, a survey was carried out in the municipality of Loulé, Algarve, a Southern temperate region of Portugal, throughout 2019, with Biogents Sentinel traps (BGS traps) and ovitraps. More than 19,000 eggs and 400 adults were identified from May 9 (week 19) and December 16 (week 50). A positive correlation between the number of females captured in the BGS traps and the number of eggs collected in ovitraps was found. The start of activity of in May corresponded to an average minimum temperature above 13.0 °C and an average maximum temperature of 26.2 °C. The abundance peak of this population was identified from September to November. The positive effect of temperature on the seasonal activity of the adult population observed highlight the importance of climate change in affecting the occurrence, abundance, and distribution patterns of this species. The continuously monitoring activities currently ongoing point to an established population of in Loulé, Algarve, in a dispersion process to other regions of Portugal and raises concern for future outbreaks of mosquito-borne diseases associated with this invasive mosquito species.
是一种入侵性蚊子，已经在几个欧洲国家以及葡萄牙殖民，它于 2017 年首次在葡萄牙被发现。为了增加对种群动态的了解，2019 年在葡萄牙南部温带地区阿尔加维的洛雷市进行了一项调查，使用了生物发生器监测器陷阱（BGS 陷阱）和诱卵器。从 5 月 9 日（第 19 周）和 12 月 16 日（第 50 周），共发现了超过 19000 个卵和 400 只成虫。发现 BGS 陷阱中捕获的雌性数量与诱卵器中收集的卵数量之间存在正相关。在 5 月开始活动，平均最低温度高于 13.0°C，平均最高温度为 26.2°C。该种群的丰度峰值出现在 9 月至 11 月。观察到温度对成虫种群季节性活动的积极影响，突出了气候变化对这种物种的发生、丰度和分布模式的影响。目前正在进行的持续监测活动表明，在洛雷市，阿尔加维已经建立了一个 的种群，正在向葡萄牙其他地区扩散，并对与这种入侵性蚊子有关的蚊媒疾病未来的爆发表示担忧。
