To study dengue vector breeding patterns under a variety of conditions in public and private spaces; to explore the ecological, biological and social (eco-bio-social) factors involved in vector breeding and viral transmission, and to define the main implications for vector control.
In each of six Asian cities or periurban areas, a team randomly selected urban clusters for conducting standardized household surveys, neighbourhood background surveys and entomological surveys. They collected information on vector breeding sites, people's knowledge, attitudes and practices surrounding dengue, and the characteristics of the study areas. All premises were inspected; larval indices were used to quantify vector breeding sites, and pupal counts were used to identify productive water container types and as a proxy measure for adult vector abundance.
The most productive vector breeding sites were outdoor water containers, particularly if uncovered, beneath shrubbery and unused for at least one week. Peridomestic and intradomestic areas were much more important for pupal production than commercial and public spaces other than schools and religious facilities. A complex but non-significant association was found between water supply and pupal counts, and lack of waste disposal services was associated with higher vector abundance in only one site. Greater knowledge about dengue and its transmission was associated with lower mosquito breeding and production. Vector control measures (mainly larviciding in one site) substantially reduced larval and pupal counts and "pushed" mosquito breeding to alternative containers.
Vector breeding and the production of adult Aedes aegypti are influenced by a complex interplay of factors. Thus, to achieve effective vector management, a public health response beyond routine larviciding or focal spraying is essential.
研究在公共和私人空间的各种条件下登革热媒介滋生模式；探讨与媒介滋生和病毒传播相关的生态、生物和社会（生态-生物-社会）因素，并确定对媒介控制的主要影响。
在六个亚洲城市或城市周边地区，每个地区的团队均随机选择城区进行标准化家庭调查、社区背景调查和昆虫学调查。他们收集有关媒介滋生地、人们对登革热的知识、态度和做法的信息，以及研究地区的特征。对所有场所进行检查；幼虫指数用于量化媒介滋生地，蛹计数用于识别有生产力的水容器类型，并作为成年媒介丰度的替代指标。
最具生产力的媒介滋生地是户外水容器，尤其是那些未覆盖、位于灌木丛下且至少一周未使用的容器。与商业和公共空间（学校和宗教设施除外）相比，家庭周边和家庭内区域对蛹的产生更为重要。供水与蛹计数之间存在复杂但无统计学意义的关联，而只有一个地点缺乏废物处理服务与更高的媒介丰度相关。对登革热及其传播的了解程度越高，蚊子滋生和繁殖的可能性越低。蚊媒控制措施（仅在一个地点进行幼虫防治）可显著降低幼虫和蛹的数量，并将蚊子滋生“推向”其他替代容器。
媒介滋生和埃及伊蚊成虫的产生受多种因素的复杂相互作用影响。因此，要实现有效的媒介管理，必须采取超越常规幼虫防治或重点喷洒的公共卫生应对措施。
