Although quantitative surveillance data for immature stages of Aedes aegypti are often used to prioritize containers or specific types of containers for control, the relationship between immature and emergent adult populations under field conditions is largely unknown. We examined the relationships between abundance of III/IV instars and pupae, and emerging adult population for a series of water storage containers in southern Vietnam. A large proportion of III/IV instars failed to progress to adulthood, and the relationships between III/IV instars and adults were poor. Collected IV instars appeared to be nutritionally deprived, although their size and nutrient levels were not reliable indicators of emergence success. Conversely, pupal abundance was a good indicator of emerging adult populations, especially over the ensuing 48-h period. Although there were clear advantages of pupal surveillance over surveillance of III/IV instars for the estimation of adult mosquito productivity, there were practical limitations associated with the enumeration of pupae, and their comparatively low densities may preclude the identification of potentially productive containers.
尽管埃及伊蚊的幼虫期的定量监测数据通常用于确定控制的重点容器或特定类型的容器，但在野外条件下，幼虫期和成虫期种群之间的关系在很大程度上是未知的。我们研究了越南南部一系列储水容器中 III/IV 龄幼虫和蛹与成虫种群之间的关系。很大一部分 III/IV 龄幼虫未能发育为成虫，并且 III/IV 龄幼虫与成虫之间的关系很差。收集到的 IV 龄幼虫似乎营养不足，尽管它们的大小和营养水平不是成虫成功发育的可靠指标。相反，蛹的丰度是成虫种群的良好指标，尤其是在随后的 48 小时内。虽然与 III/IV 龄幼虫的监测相比，蛹的监测在估计成蚊生产力方面具有明显的优势，但在对蛹进行计数方面存在实际限制，并且它们相对较低的密度可能会排除潜在有生产力的容器的识别。
