Resumo: Dengue fever is an infectious disease whose agent is an arbovirus, which has four serotypes. Despite the availability of a vaccine in an experimental stage and with promising results it is not yet available for the general population. Therefore, the control of dengue is still based on the reduction of vector density, eliminating containers with clean water that act as mosquito breeding sites. This study aimed to evaluate the types of breeding sites and water with the purpose of better understanding the containers colonized by this species and contributing to the improvement of control actions. In 14 months of collection, between October and April from 2003 to 2005, larvae and pupae were collected and the following variables were measured: volume, dissolved oxygen (DO), pH, electrical conductivity and temperature of the water from the breeding sites. High rates of variation were observed for all measured parameters and larvae were recorded in water containing oil residue, rust, paint, salt and a high concentration of organic matter. These results show that the breeding sites of Ae. aegypti are not the classic "containers with clean water". These findings bring more difficulties and other implications for vector control. It is suggested that such knowledge should be included in the content of courses for health workers, as well as in campaigns and dengue prevention programs, helping to address the problem.
