Monitoring the invasion process of the Asian tiger mosquito Aedes albopictus and its interaction with the contender Aedes aegypti, is critical to prevent and control the arthropod-borne viruses (i.e., Arboviruses) they transmit to humans. Generally, the superior ecological competitor Ae. albopictus displaces Ae. aegypti from most geographic areas, with the combining factors of biology and environment influencing the competitive outcome. Nonetheless, detailed studies asserting displacement come largely from sub-tropical areas, with relatively less effort being made in tropical environments, including no comprehensive research about Aedes biological interactions in Mesoamerica. Here, we examine contemporary and historical mosquito surveillance data to assess the role of shifting abiotic conditions in shaping the spatiotemporal distribution of competing Aedes species in the Republic of Panama. In accordance with prior studies, we show that Ae. albopictus has displaced Ae. aegypti under suboptimal wet tropical climate conditions and more vegetated environments within the southwestern Azuero Peninsula. Conversely, in the eastern Azuero Peninsula, Ae. aegypti persists with Ae. albopictus under optimal niche conditions in a dry and more seasonal tropical climate. While species displacement was stable over the course of two years, the presence of both species generally appears to fluctuate in tandem in areas of coexistence. Aedes albopictus was always more frequently found and abundant regardless of location and climatic season. The heterogenous environmental conditions of Panama shape the competitive outcome and micro-geographic distribution of Aedes mosquitoes, with potential consequences for the transmission dynamics of urban and sylvatic zoonotic diseases.

监测亚洲虎蚊白纹伊蚊的入侵过程及其与竞争者埃及伊蚊的相互作用，对于预防和控制节肢动物传播给人类的节肢动物病毒（即虫媒病毒）至关重要。一般来说，优越的生态竞争对手Ae。白纹伊蚊取代了Ae。埃及伊蚊来自大多数地理区域，生物学和环境因素共同影响竞争结果。尽管如此，断言流离失所的详细研究主要来自亚热带地区，在热带环境中所做的努力相对较少，包括没有关于中美洲伊蚊生物相互作用的全面研究。在这里，我们研究了当代和历史的蚊子监测数据，以评估非生物条件的变化在塑造巴拿马共和国伊蚊竞争物种时空分布方面的作用。根据先前的研究，我们表明Ae。白纹伊蚊已取代伊蚊。埃及伊蚊在次优潮湿热带气候条件和阿苏罗半岛西南部植被较多的环境下生长。相反，在阿苏罗半岛东部， Ae。埃及伊蚊持续存在于伊蚊中。在干燥且更具季节性的热带气候中，白纹伊蚊处于最佳生态位条件下。虽然物种迁移在两年内保持稳定，但这两个物种的存在通常在共存地区似乎同时波动。无论地点和气候季节如何，白纹伊蚊的发现频率和数量总是更高。 巴拿马的异质环境条件决定了伊蚊的竞争结果和微观地理分布，对城市和森林人畜共患疾病的传播动态产生潜在影响。
