In a region of high dengue incidence, on the coast of the State of São Paulo, 9 areas were selected to evaluate the behavior of immature Aedes aegypti.
The 9 areas were grouped into 4 strata according to soil use and occupation. Larvae and pupas were collected in a sample of approximately 500 buildings in each area.
Although tires and canvas presented the highest positive rates for Aedes aegypti, drains and other containers fixed to the buildings were highly predominant among positive containers; 32 to 76% of the positive containers in the 4 study strata. Public areas of apartment buildings and large non-residential premises presented the highest positive rates for Aedes Aegypti, while apartments presented the lowest. Infestation levels were greater in residential areas with predominance of apartment buildings, where 76% of the breeding sites detected were containers fixed to the buildings.
This knowledge is an important tool in the control strategy, since it reinforces the need for special attention regarding certain types of buildings and the adjustment of technical norms for pluvial water drains and improvement of building maintenance. Moreover, systematic observations are required to follow-up the occupancy dynamic of different buildings and containers by Aedes aegypti and the incorporation of this knowledge in the control of vectors in the region.
在圣保罗州海岸登革热高发地区，选取了9个区域来评估埃及伊蚊幼虫的生存情况。
根据土地使用和占用情况，将这9个区域分为4个层次。在每个区域约500栋建筑物的样本中收集幼虫和蛹。
尽管轮胎和帆布中埃及伊蚊的阳性率最高，但在阳性容器中，固定在建筑物上的排水沟和其他容器占主导地位；在4个研究层次中，阳性容器占32%至76%。公寓楼和大型非住宅场所的公共区域埃及伊蚊阳性率最高，而公寓的阳性率最低。在以公寓楼为主的居民区，滋生水平更高，其中76%的检测滋生地是固定在建筑物上的容器。
这些信息是控制策略中的重要工具，因为它强化了对某些类型建筑物给予特别关注的必要性，以及调整雨水排水技术规范和改善建筑物维护的必要性。此外，需要进行系统观察，以跟踪埃及伊蚊对不同建筑物和容器的占用动态，并将这些信息纳入该地区病媒控制工作中。
