The mosquito Aedes albopictus is a vector of several arboviruses transmitted to humans. They have a sylvatic behavior, occurring in rural areas. However, reports of their adaptation to anthropic environments have been increasing. The aim of this study is to investigate the presence and distribution of Ae. albopictus in the Metropolitan Region of Belém in the Brazilian Amazon and evaluate its preference for either natural or artificial breeding sites under the weather conditions of the Amazon. Ovitraps (artificial breeding sites) and bamboo internodes (natural breeding sites) were deployed in neighborhood peridomiciles during the dry and rainy seasons. The results showed that the presence of Ae. albopictus was recorded in 71.4% of the neighborhoods during the dry season and in 69.2% neighborhoods during the rainy season, thus indicating a wide distribution in the region. A significant increase in the frequency of the capture of mosquitoes in areas with higher vegetation cover was observed during the dry season (R² = 0.2995; p=0.018) but not during the rainy season (R² = 0.044; p=0.43). Comparing the weekly frequency of Ae. albopictus on positive bamboos and OVT, no significant difference was observed between them (t= 0.559; df= 23; p=0.58). A significant increase in the number of positive breeding sites was observed with increased rainfall for both bamboo (R² = 0.33; p= 0.002) and OVT (R² = 0.24; p= 0.013). This is the first report of Ae. albopictus in the metropolitan area of Belém. The findings suggest a wide distribution in the studied area, preferably in areas with more extensive vegetation cover. Additionally, the mosquito population showed the ability to use both natural and artificial habitats.

白纹伊蚊 (Skuse) 在巴西亚马逊地区贝伦大都市区的分布和偏好

白纹伊蚊是传播给人类的几种虫媒病毒的载体。他们有一种森林行为，发生在农村地区。然而，关于它们适应人类环境的报道一直在增加。本研究的目的是调查Ae 的存在和分布。albopictus在巴西亚马逊的贝伦都会区，并评估其在亚马逊天气条件下对自然或人工繁殖地的偏好。在旱季和雨季，在附近的小区周围部署了诱卵器（人工繁殖地）和竹节间（自然繁殖地）。结果表明存在Ae。白纹鱼旱季有 71.4% 的街区，雨季有 69.2% 的街区，表明该地区分布广泛。在旱季（R ² = 0.2995；p=0.018），但在雨季（R ² = 0.044；p=0.43）观察到在植被覆盖较高的地区捕获蚊子的频率显着增加。比较Ae 的每周频率。albopictus在阳性竹子和 OVT 上的差异无统计学意义（t=0.559；df=23；p=0.58）。^{随着竹子 (R 2} = 0.33; p = 0.002) 和 OVT (R ² )降雨量的增加，阳性繁殖地的数量显着增加= 0.24; p = 0.013)。这是Ae的第一份报告。贝伦大都市区的白纹病。研究结果表明，研究区域分布广泛，最好是在植被覆盖范围更广的区域。此外，蚊子种群显示出使用自然和人工栖息地的能力。
