RESUMO
INTRODUCTION: Here, we evaluated sweeping methods used to estimate the number of immature Aedes aegypti in large containers. METHODS: III/IV instars and pupae at a 9:1 ratio were placed in three types of containers with, each one with three different water levels. Two sweeping methods were tested: water-surface sweeping and fi ve-sweep netting. The data were analyzed using linear regression. RESULTS: The fi ve-sweep netting technique was more suitable for drums and water-tanks, while the water-surface sweeping method provided the best results for swimming pools. CONCLUSIONS: Both sweeping methods are useful tools in epidemiological surveillance programs for the control of Aedes aegypti.
