Resumo
The present study aimed to evaluate the risk of Aedes aegypti proliferation in structures used in compensatory techniques for urban drainage (Best Management PracticesBMPs). These drainage structures are utilised to reduce flood peaks due to surface runoff, and they have been used in many countries. However, many of these structures have been designed to keep water surfaces exposed for a certain period of time, depending on the type of project. Exposed water surfaces may become an ideal environment for A. aegypti proliferation in tropical and subtropical areas where the rainy season occurs during the summer. Thus, data regarding the mosquito life cycle, consecutive rainfall pattern and emptying time of these structures were collected. A comparison of these data led to the evaluation of the associated risk of A. aegypti proliferation in BMP structures. The risk of mosquito proliferation ranged from 1.1% to 3.3%, depending on the rainfall pattern, A. aegypti life cycle phase and BMP activity.
