Aedes albopictus (Skuse) and Aedes aegypti L. (Diptera: Culicidae) are invasive species known for their notable expansion capacity, which makes them relevant in the context of public health due to their role as vectors. In Argentina, these species coexist in a limited subtropical area in Northeastern part of the country. Because of the limited knowledge existing about these species in this region, the present study aims to investigate the determinants of the presence and abundance of both vectors at the larval habitat scale (presence and abundance) and neighbourhood scale (House, Container and Breteau Indices; abundance; and number of pupae). For this purpose, preimaginal stages of Ae. albopictus and Ae. aegypti were sampled in households from areas with variable urbanisation degrees (in rural, vegetated urban and non-vegetated urban) located in the province of Misiones, Argentina. The analyses considered the association with meteorological variables (temperature and precipitation), environmental variables (type of urbanisation), biotic variables (presence of predator species) and container characteristics (size and water volume). At the larval habitat scale, Ae. albopictus was associated with precipitation, temperature and rural environments. In contrast, Ae. aegypti was positively associated with urban environments and negatively with predator presence. At the neighbourhood scale, Ae. albopictus was primarily associated with precipitation and temperature, whereas Ae. aegypti showed a negative association with predator presence and positive associations with urban environments and, to a lesser degree, meteorological variables. These results indicate that in Argentina, meteorological, biotic and environmental factors have differential influences on Ae. albopictus and Ae. aegypti, underscoring the need to consider them for the development of effective public health strategies.
白纹伊蚊（Skuse）和埃及伊蚊（L.）（双翅目：蚊科）是具有显著扩张能力的入侵物种，因其作为病媒的作用，在公共卫生领域具有重要意义。在阿根廷，这些物种共存于该国东北部一个有限的亚热带地区。由于该地区对这些物种的了解有限，本研究旨在调查这两种病媒在幼虫栖息地尺度（存在和丰度）和邻里尺度（房屋、容器和布雷托指数；丰度；蛹的数量）上存在和丰度的决定因素。为此，在阿根廷米西奥内斯省不同城市化程度地区（农村、植被覆盖的城市和无植被的城市）的家庭中对白纹伊蚊和埃及伊蚊的未成熟阶段进行了采样。分析考虑了与气象变量（温度和降水）、环境变量（城市化类型）、生物变量（捕食者物种的存在）和容器特征（大小和水量）的关联。在幼虫栖息地尺度上，白纹伊蚊与降水、温度和农村环境有关。相比之下，埃及伊蚊与城市环境呈正相关，与捕食者的存在呈负相关。在邻里尺度上，白纹伊蚊主要与降水和温度有关，而埃及伊蚊与捕食者的存在呈负相关，与城市环境呈正相关，在较小程度上与气象变量呈正相关。这些结果表明，在阿根廷，气象、生物和环境因素对白纹伊蚊和埃及伊蚊有不同的影响，强调在制定有效的公共卫生策略时需要考虑这些因素。
