To evaluate the most productive types of properties and containers for Aedes aegypti and the spatial distribution of entomological indices.
Between December 2006 and February 2007, the vector's immature forms were collected to obtain entomological indices in 9,875 properties in the Jaguare neighborhood of Sao Jose do Rio Preto, SP, Southeastern Brazil. In March and April 2007, a questionnaire about the conditions and characteristics of properties was administered. Logistic regression was used to identify variables associated with the presence of pupae at the properties. Indices calculated per block were combined with a geo-referenced map, and thematic maps of these indices were obtained using statistical interpolation.
The properties inspected had the following Ae. aegypti indices: Breteau Index = 18.9, 3.7 larvae and 0.42 pupae per property, 5.2 containers harboring Ae. aegypti per hectare, 100.0 larvae and 11.6 pupae per hectare, and 1.3 larvae and 0.15 pupae per inhabitant. The presence of yards, gardens and animals was associated with the presence of pupae.
Specific types of properties and containers that simultaneously had low frequencies among those positive for the vector and high participation in the productivity of larvae and pupae were not identified. The use of indices including larval and pupal counts does not provide further information beyond that obtained from the traditional Stegomyia indices in locations with characteristics similar to those of São José do Rio Preto. The indices calculated per area were found to be more accurate for the spatial assessment of infestation. The Ae. aegypti infestation levels exhibited extensive spatial variation, indicating that the assessment of infestation in micro areas is needed.
评估埃及伊蚊最易孳生的物业类型和容器，并分析昆虫学指标的空间分布。
2006 年 12 月至 2007 年 2 月期间，在巴西东南部圣若泽-里约普雷图市 Jaguare 街区的 9875 处物业中采集蚊虫的幼虫和蛹，以获取昆虫学指标。2007 年 3 月和 4 月，我们对物业的状况和特征进行了问卷调查。使用逻辑回归来确定与物业存在蛹相关的变量。对每个街区计算的指数与地理参考地图相结合，并使用统计插值法获得这些指数的专题地图。
检查的物业具有以下埃及伊蚊指数：布雷图指数 = 18.9，每处物业有 3.7 只幼虫和 0.42 只蛹，每公顷有 5.2 个埃及伊蚊容器，每公顷有 100.0 只幼虫和 11.6 只蛹，每 100 个居民有 1.3 只幼虫和 0.15 只蛹。有院子、花园和动物的物业更易存在蛹。
未发现同时具有低流行率和高幼虫及蛹孳生率的特定类型物业和容器。在与圣若泽-里约普雷托特征相似的地区，使用包括幼虫和蛹计数在内的指数并不能提供比传统的 Stegomyia 指数更多的信息。按面积计算的指数更适合对感染程度进行空间评估。埃及伊蚊的感染水平表现出广泛的空间差异，这表明需要对小区域的感染情况进行评估。
