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 five-sweep netting. The data were analyzed using linear regression.
Results
The five-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.
