Coastal development is expanding globally in response to mass human migration, yet urban planning guidelines often overlook the problems that human encroachment on or near coastal mosquito habitat may cause. This study aimed at elucidating the frequency and magnitude of dispersal of highly vagile saltmarsh mosquitoes from productive off-shore bay islands to adjacent coastal human developments. Inter-population dynamics and daily host-seeking activity of saltmarsh mosquitoes were monitored daily at 15-min intervals within a productive bay island and adjacent coastal development in southeast Queensland, Australia, using emerging smart trap technology over a 2-month period of high mosquito activity. The regulation of mosquito dispersal and host-seeking activity by local environmental factors, e.g. temperature, relative humidity and hourly wind patterns, were also investigated. The data show that the primary saltmarsh mosquitoes Aedes vigilax (Skuse) and Culex sitiens (Wiedemann) disperse from offshore breeding sites to neighboring mainland areas in high numbers and in highly synchronized waves despite unfavorable wind patterns and the need to traverse a considerable expanse (ca. 1.4 km) of open water. Patterns of host-seeking activity within each site were also remarkably similar despite notable differences in the local environment demonstrating a consistency in host-seeking activity across disparate habitats. These findings demonstrate that distant saltmarsh habitats, including offshore breeding sites, are likely to be primary sources of mosquito nuisance for coastal housing developments. This observation highlights the need to develop new planning and regulatory guidelines that alert urban planners to the risks of encroaching on habitats close to sources of highly vagile mosquito species.

响应人类大规模迁徙，沿海地区的发展正在全球范围内扩展，但是城市规划指南通常忽略了人类侵占沿海蚊子栖息地或附近地区可能引起的问题。这项研究的目的是阐明高度易变的盐沼蚊子从生产性近海海湾岛屿向邻近的沿海人类开发的扩散频率和强度。在澳大利亚昆士兰东南部的一个生产性海湾岛屿和邻近的沿海开发中，使用新兴的智能诱集技术，在两个月的高蚊期中，每天隔15分钟监测一次盐沼蚊子的种群间动态和每日寄主活动活动。蚊子的散布和寻求宿主活动受当地环境因素（例如温度，还研究了相对湿度和小时风模式。数据显示，原盐沼蚊子伊蚊（Skuse）和库蚊（Wiedemann）尽管风势不利并且需要穿越相当宽的广阔水域（约1.4公里），但仍以高频率和高度同步的波数从海域繁殖场散布到邻近的大陆地区。尽管当地环境存在显着差异，表明每个地点的寄主寻求活动模式也非常相似，这表明跨不同生境的寄主寻求活动具有一致性。这些发现表明，遥远的盐沼栖息地，包括近海繁殖地，很可能是沿海房屋开发中蚊虫滋扰的主要来源。该观察结果突出表明，有必要制定新的规划和法规指南，以提醒城市规划人员注意接近高度易变的蚊子物种来源的栖息地的风险。
