While the development of land for residential housing along the Swan and Canning Rivers in Perth, WA, Australia has reduced natural mosquito breeding sites, the role of backyard container breeding remains a relatively unknown factor. Local Governments responsible for these areas focus management and control efforts on low lying, tidally driven mosquito habitats to control (Skuse) and (Thomson) mosquitoes in an effort to reduce both the nuisance and disease risk to residents. In spite of their efforts, Local Governments continue to receive complaints regarding mosquito nuisance, even when environmental conditions do not favor hatching and development of the two species in the Swan River tidal flats. In this study, 150 backyard inspections were conducted in the residential suburb of Bassendean, Perth, WA, Australia, situated in close proximity to the Swan River tidal plain. The occurrence and species composition of the mosquito fauna found in residential backyards was documented. Of the backyards inspected, 94% were found to possess containers capable of breeding mosquitoes, although only 3% contained mosquito larvae. Nine species of mosquito were collected from containers ranging in capacity from 0.05 to 50 L across the study area. Additionally, encephalitis virus surveillance trapping was conducted within residential properties and compared to the tidally driven natural habitat at Ashfield Flats and a tidally influenced brackish creekline at Bindaring Park. The species composition of the fauna at the three habitat types differed significantly, with (Skuse) dominating residential lots and more prevalent at the saltmarsh site. Bindaring Park had an adult composition at the mid-point of these two habitats, reflecting its proximity to both the Swan River and residential lots.
虽然澳大利亚西澳大利亚州珀斯市天鹅河和坎宁河沿岸用于住宅建设的土地开发减少了天然蚊子繁殖地,但后院容器繁殖的作用仍是一个相对未知的因素。负责这些区域的地方政府将管理和控制工作重点放在地势低洼、受潮汐驱动的蚊子栖息地,以控制斯克塞蚊(Skuse)和汤姆森蚊(Thomson),努力减少对居民的滋扰和疾病风险。尽管他们做出了努力,但地方政府仍不断收到有关蚊子滋扰的投诉,即使环境条件不利于这两种蚊子在天鹅河潮滩孵化和生长。在本研究中,对位于澳大利亚西澳大利亚州珀斯市巴森德恩住宅区进行了150次后院检查,该住宅区紧邻天鹅河潮滩平原。记录了住宅后院发现的蚊子种类及其组成。在检查的后院中,94%被发现有能够滋生蚊子的容器,尽管只有3%含有蚊子幼虫。在整个研究区域,从容量为0.05升至50升的容器中收集到了9种蚊子。此外,在住宅区内进行了脑炎病毒监测诱捕,并与阿什菲尔德滩涂受潮汐驱动的自然栖息地以及宾达林公园受潮汐影响的咸淡水溪流进行了比较。三种栖息地类型的蚊子种类组成有显著差异,斯克塞蚊(Skuse)在住宅区占主导,而在盐沼地更为常见。宾达林公园的成虫组成处于这两种栖息地的中间点,反映了其与天鹅河和住宅区的接近程度。
