Mosquito populations associated with the heavily urbanised Cooks River and Wolli Creek estuaries, Sydney, Australia, were investigated to assist in identifying potential pest and public health threats and assist local authorities in developing management strategies. Adult mosquitoes were sampled using carbon dioxide baited light traps at five locations, including two sites alongside Cooks River (Steel Park and Gough Whitlam Park), two sites alongside Wolli Creek (Jackson Track and Turella Reserve) as well as an additional location, Barton Park (Muddy Creek). These locations represented at least one of three distinct landscape characteristics, dominated either by bushland, parkland, or estuarine wetland habitats. Three trap sites were established at each location and sampling adult host-seeking mosquitoes took place on a weekly basis for 4 weeks. All mosquito specimens were identified to determine differences in relative abundance and community composition. There was a distinct difference in the abundance and community composition of mosquitoes collected between the five locations with the differences due to the presence and abundance of Aedes vigilax, Culex sitiens, Aedes notoscriptus Those locations close to estuarine wetlands were dominated by A. vigilax while other sites were dominated by mosquitoes associated with urban habitats such as stormwater infrastructure or backyard water-holding containers (e.g. A. notoscriptus and Culex quinquefasciatus). Sites adjacent to urban bushland contained a higher species richness, but not necessarily greater abundance, of mosquitoes than other sites. This study provided an insight into mosquito populations within a previously unstudied area of Sydney and highlight that local authorities should carefully consider wetland management and urban planning strategies in the future to assist in identifying potential risks of nuisance-biting, mosquito-borne disease and in determining the need for further public health action.

对与澳大利亚悉尼的高度城市化的库克斯河和沃利河河口相关的蚊子种群进行了调查，以帮助识别潜在的害虫和公共卫生威胁，并协助地方当局制定管理策略。在五个地点使用二氧化碳诱饵诱捕器对成年蚊子进行采样，包括库克斯河沿岸的两个地点（钢公园和高夫惠特拉姆公园）、涡拉溪沿岸的两个地点（杰克逊步道和图雷拉保护区）以及另一个地点巴顿公园（泥泞的小溪）。这些位置代表了三种不同景观特征中的至少一种，主要是灌木丛、公园或河口湿地栖息地。在每个位置建立了三个诱捕点，每周对成年寻找寄主的蚊子进行采样，持续 4 周。鉴定了所有蚊子标本以确定相对丰度和群落组成的差异。五个地点之间收集的蚊子的丰度和群落组成存在明显差异，差异是由于存在和丰度Aedes vigilax, Culex sitiens , Aedes notoscriptus靠近河口湿地的那些地点主要以A. vigilax为主，而其他地点以与城市栖息地相关的蚊子为主，例如雨水基础设施或后院储水容器（例如A. notoscriptus和Culex quinquefasciatus）。与城市丛林相邻的地点比其他地点的蚊子物种丰富度更高，但不一定更丰富。这项研究深入了解了悉尼以前未研究过的区域内的蚊子种群，并强调地方当局应仔细考虑未来的湿地管理和城市规划策略，以帮助确定滋扰叮咬、蚊媒疾病的潜在风险，并确定需要采取进一步的公共卫生行动。
