目前，埃及伊蚊Aedes Aegypti(L.)正在制定控制策略，包括在成虫阶段操纵媒介(例如，使用细菌内共生菌Wolbachia来缩短媒介种群的寿命)。这些新的战略需要成人抽样方法来衡量人口规模、结构(年龄、性别比)的变化，并最终衡量该计划的成功。每种抽样方法都有一定的偏差。一旦定义了这些偏差，就可以相应地校准用于估计种群大小和结构的方法，从而产生对媒介种群更准确和更复杂的估计。对成虫进行了一系列的标记-释放-再捕获实验。埃及伊蚊是在澳大利亚昆士兰州北部的一个大型室外飞行笼子和一个室内环境中进行的。对BG-Sentinel陷阱(BGS)的偏差进行了调查，包括以下几个类别：1)蚊龄；2)性别；3)生理状态；4)体型。没有检测到不同年龄段或不同体型的人存在偏见。在生理组之间检测到了显著的偏差：未分娩的女性的再获得率明显低于所有其他组，但血液喂养的经产女性的再获得率也很低。雄性的再捕获率高于所有组，但只有雄性和未分娩的雌性之间的再捕获率有显著差异。以往的研究表明，BGS是治疗Ae的一种高效工具。埃及伊蚊监控系统。事实证明，BGS是一种可靠的人工智能工具。埃及伊蚊监测，采样结果一致。BGS的抽样偏差是可测量的，可以用来产生对成年人口及其属性的更准确的估计。
Currently, Aedes aegypti (L.) control strategies are being developed that involve manipulation of the vector at the adult stage (e.g., the use of the bacterial endosymbiont Wolbachia to shorten the life span of the vector population). These novel strategies demand adult sampling methods to measure changes in population size, structure (age, sex ratio), and, ultimately, the success of the program. Each sampling method presents certain biases. Once these biases are defined, methods used to estimate population size and structure can be calibrated accordingly, resulting in more accurate and complex estimates of the vector population. A series of mark-release-recapture experiments with adult Ae. aegypti were conducted in a large outdoor flight cage and an indoor setting in far north Queensland, Australia. The biases of the BG-Sentinel trap (BGS) were investigated across several categories, as follows: 1) mosquito age; 2) sex; 3) physiological status; and 4) body size. Biases were not detected across age groups or body sizes. A significant bias was detected across physiological groups: nulliparous females were recaptured at a significantly lower rate than all other groups except blood-fed parous females, which were also recaptured at a low rate by the BGS. Males were recaptured at a higher rate than all groups, but only a significant difference in recapture rates was observed between males and nulliparous females. Previous studies show that the BGS is a highly effective tool for Ae. aegypti surveillance. The BGS proves to be a reliable tool in Ae. aegypti surveillance with consistent sampling outcomes. The sampling bias of the BGS is measurable and can be used to generate more accurate estimates of the adult population and its attributes.
