The survival and dispersal of adult Aedes notoscriptus (Skuse) were estimated in Brisbane, Queensland, Australia, where this species has been identified as a vector of Ross River and Barmah Forest viruses and shown to be orally susceptible to dengue virus types 1-4. Standard mark-release-recapture methods were used. Before the field study, laboratory trials showed that marking Ae. notoscriptus with fluorescent powder had no effect on survivorship. Female recapture rates of 10.6 and 2.3% over an 8-d period were achieved for two cohorts of marked Ae. notoscriptus released at the same field site. No males were recaptured over the 8-d period. The probability of daily survival was calculated using the Saul model as 0.77 and 0.79 for blue- and pink-marked females, respectively. For blue- and pink-marked females, the mean distance traveled was 105.2 and 179.9 m, and the maximum distance traveled was 195 and 238 m, respectively. The results indicate that protected harborage sites and shade influenced the distribution of Ae. notoscriptus within the study site.
在澳大利亚昆士兰州布里斯班对成年致倦库蚊（Skuse）的存活和扩散情况进行了评估，该物种已被确定为罗斯河病毒和巴马森林病毒的传播媒介，并且已证明对1 - 4型登革病毒具有口服易感性。采用了标准的标记释放再捕获方法。在实地研究之前，实验室试验表明用荧光粉标记致倦库蚊对其存活率没有影响。在同一实地地点释放的两组标记致倦库蚊在8天时间内的雌性再捕获率分别为10.6%和2.3%。在这8天期间没有捕获到雄性。使用索尔模型计算得出，蓝色标记和粉色标记雌性的每日存活概率分别为0.77和0.79。对于蓝色标记和粉色标记的雌性，平均移动距离分别为105.2米和179.9米，最大移动距离分别为195米和238米。结果表明，受保护的栖息场所和阴凉处影响了致倦库蚊在研究地点内的分布。
