【 摘 要 】

The present work aimed to estimate the effect of water quality in the development of Aedes aegypti (Linnaeus, 1762). The life cycle of this vector was studied in raw sewage water, effluent of UASB reactor, effluent of polishing lagoon, effluent of anaerobic filter, rainwater and de-chlorinated water. The development period, egg viability and larval and pupal survival were evaluated daily as well as the adult longevity and fecundity. The duration of larval period showed a variation of 5.6 to 9.1 days. Survival was considered low in raw sewage water, effluent of UASB reactor, effluent of polishing lagoon and effluent of anaerobic filter. No difference in terms of the duration and egg and pupal viability nor in the adult longevity and fecundity was detected. It was verified that despite a reduction in larval viability, A. aegypti could accomplish total development in waters with high pollution degree and that all the treatments were suitable to the development of this vector.
