As dengue continues to emerge as a major public-health problem world-wide, efforts to control the dengue vector Aedes aegypti must become more effective and efficient. Results from larval and pupal surveys applied in Venezuela illustrate the uniqueness of the information gained from pupal surveys; information that is lost when traditional Stegomyia indices are calculated. As most Ae. aegypti pupae will emerge to become adults, controlling the containers that produce the most pupae could have the greatest impact on the adult population. Pupal-survey results in Venezuela showed that large (150- to 200-litre) water drums produce the greatest number of pupae throughout the year. In the rainy season, approximately 70% of all pupae are found in these drums or in tyres, buckets and tanks. Over 80% of pupae in the dry season are found in drums and tanks alone. By targeting only those domestic breeding containers that produce the greatest number of pupae, control efforts may be streamlined to have the greatest impact on reducing the local adult Ae. aegypti population.
随着登革热持续成为全球主要的公共卫生问题，控制登革热媒介埃及伊蚊的工作必须变得更加有效和高效。在委内瑞拉进行的幼虫和蛹调查结果表明了蛹调查所获信息的独特性；而这些信息在计算传统白纹伊蚊指数时会丢失。由于大多数埃及伊蚊蛹会羽化为成虫，控制产生最多蛹的容器可能对成虫数量产生最大影响。委内瑞拉的蛹调查结果显示，大型（150至200升）水桶全年产生的蛹数量最多。在雨季，所有蛹中约70%出现在这些水桶或轮胎、水桶和水箱中。仅在旱季，超过80%的蛹仅出现在水桶和水箱中。通过仅针对那些产生最多蛹的家庭繁殖容器，控制工作可以得到简化，从而对减少当地埃及伊蚊成虫数量产生最大影响。
