季节性变化的容器生产力和感染水平的埃及伊蚊进行了评估，在里约热内卢，贫民窟和郊区附近的城市化程度不同的两个领域。四个最具生产力的容器可以产生高达90%的总产量。大型和开口容器，如水箱和金属桶，位于户外是最具生产力的，在这两个地区，高达47.49%的总Ae。在郊区阴影处采集埃及伊蚊。在旱季和雨季，水箱被确定为这两个地区的主要容器。集装箱生产率因季节和城市化程度而异。郊区每户平均感染人数高于郊区，但各地区间季节差异不显著（P > 0.05）。在这两个地方都观察到高的虫害指数，郊区的房屋指数为20.5-21.14，市区为9.56-11.22。本报告为更集中和更具成本效益的Ae提供了潜在的支持。在里约热内卢的埃及控制。
Seasonal variation in container productivity and infestation levels by Aedes aegypti were evaluated in two areas with distinct levels of urbanization degrees in Rio de Janeiro, a slum and a suburban neighborhood. The four most productive containers can generate up to 90% of total pupae. Large and open-mouthed containers, such as water tanks and metal drums, located outdoors were the most productive in both areas, with up to 47.49% of total Ae. aegypti pupae collected in the shaded sites in the suburban area. Water-tanks were identified as key containers in both areas during both the dry and rainy seasons. Container productivity varied according to seasons and urbanization degree. However, the mean number of pupae per house was higher in the suburban area, but not varied between seasons within each area (P > 0.05). High infestation indexes were observed for both localities, with a house index of 20.5-21.14 in the suburban and of 9.56-11.22 in the urban area. This report gives potential support to a more focused and cost-effective Ae. aegypti control in Rio de Janeiro.
