As mosquito-borne diseases are a growing human health concern in the United States, the distribution and potential arbovirus risk from container-breeding Aedes mosquitoes is understudied in the southern Great Plains. The aim of the study was to assess landscape and anthropogenic factors associated with encountering adult container-breeding mosquitoes in small cities in southern Oklahoma. Collections were carried out over a 10 week period from June to August 2017 along two geographical transects, each consisting of three cities, equally distant from the Red River/Texas border. Mosquitoes were collected weekly using two trap types along with data for 13 landscape, vegetation, and anthropogenic variables. After five rounds of collection, 6628 female mosquitoes were collected over 2110 trap-nights involving 242 commercial or residential sites in six cities. Of the mosquitoes collected, 80% consisted of container-breeding species: Aedes albopictus (72%), Culex pipiens complex (16%) and Aedes aegypti (8%). Regionally, Aedes aegypti was more likely present in cities closest to the Texas border while Ae. albopictus was spread throughout the region. In general, Ae. aegypti and Ae. albopictus were significantly more present in sites featuring no or low vegetation and residential sites. Variables associated with Ae. albopictus presence and abundance varied between cities and highlighted the urban nature of the species. The study highlighted the distribution of Ae. aegypti geographically and within the urban context, indicated potential habitat preferences of container-breeding mosquito species in small towns, and demonstrated the usefulness of Gravid Aedes traps (GAT) traps for monitoring Aedes populations in urban habitats in small cities.

大平原南部小城市成年伊蚊和白纹伊蚊的景观和人为因素

由于在美国，蚊媒疾病日益成为人类健康关注的焦点，容器繁殖伊蚊的分布和潜在的虫媒病毒风险大平原南部对蚊子的研究较少。该研究的目的是评估与俄克拉荷马州南部小城市中的成年容器繁殖蚊子相遇相关的景观和人为因素。从2017年6月至2017年8月的10个星期内，沿两个地理样面进行了采集，每个样面包括三个与红河/得克萨斯州边界等距的城市。每周使用两种诱捕器类型收集蚊子，并收集13种景观，植被和人为变量的数据。经过五轮收集，在2110个诱捕夜中收集了6628只雌性蚊子，涉及六个城市的242个商业或住宅场所。在收集的蚊子中，有80％由容器繁殖物种组成：白纹伊蚊（72％），淡色库蚊（16％）和埃及伊蚊（8％）。在地区上，埃及伊蚊更可能出现在距离德克萨斯州边境最近的城市中，而伊蚊。白化病遍布整个地区。在一般情况下，阂。埃及和埃及。白化病在没有植被或低植被的地区和居民区中的比例明显更高。与Ae关联的变量。不同城市之间白带的存在和丰度各不相同，突显了该物种的城市性质。该研究突出了Ae的分布。埃及在地理上和城市范围内，表明了小城镇中集装箱繁殖蚊子的潜在栖息地偏爱，并展示了Gravid Aedes诱集器（GAT）诱集器用于监测小城市中城市栖息地中伊蚊的数量。
