Extended drought conditions in south-east Queensland during the early 2000s have resulted in a culture of water harvesting and legislated water restrictions. Aedes notoscriptus is a container-breeding mosquito vector of Ross River and Barmah Forest viruses.
From 2008-2009, the larval habitats and seasonal abundance of domestic container-breeding mosquitoes were recorded from three suburbs of Brisbane. A knowledge, attitudes and practice questionnaire was administered to householders. A low-cost, desktop methodology was used to predict the proportion of shaded premises compared with front-of-property estimates.
We highlight changes in the frequency of container categories for A. notoscriptus as a response to human behavioural changes to drought. Garden accoutrements, discarded household items and water storage containers accounted for 66.2% (525/793) of positive containers and 77.5% (73 441/94 731) of all immature mosquitoes. Of all household premises surveyed, 52.6% (550/1046) contained rainwater tanks and 29.4% (308/1046) harvested water in other containers, contrasting with a previous 1995 survey where neither category was observed. Both Premise Condition Index and shade directly correlated with positive premises.
Human response to drought has resulted in new habitats for domestic container-breeding mosquitoes. This recent trend of prolific water storage is similar to earlier years (1904-1943) in Brisbane when Aedes aegypti was present and dengue epidemics occurred.
21世纪初，昆士兰州东南部长期干旱，导致了雨水收集文化的形成以及法定的用水限制。致倦库蚊是罗斯河病毒和巴马森林病毒的容器孳生蚊媒。
2008年至2009年，记录了布里斯班三个郊区家庭容器孳生蚊幼虫的栖息地和季节性数量。对住户进行了知识、态度和行为问卷调查。采用一种低成本的桌面方法来预测房屋遮荫比例，并与房屋正面的估计值进行比较。
我们强调了致倦库蚊容器种类频率的变化，这是对人类应对干旱行为变化的一种反应。园艺用品、废弃的家居用品和储水容器占阳性容器的66.2%（525/793），占所有未成熟蚊子的77.5%（73441/94731）。在所有接受调查的家庭中，52.6%（550/1046）有雨水箱，29.4%（308/1046）在其他容器中收集雨水，这与1995年的一项先前调查形成对比，当时这两类情况均未观察到。房屋状况指数和遮荫程度均与阳性房屋直接相关。
人类对干旱的应对导致了家庭容器孳生蚊的新栖息地。最近这种大量储水的趋势与布里斯班早些年（1904 - 1943年）相似，当时存在埃及伊蚊且发生了登革热疫情。
