Evaluation of two sweeping methods for estimating the number of immature Aedes aegypti (Diptera: Culicidae) in large containers

Here, we evaluated sweeping methods used to estimate the number of immature Aedes aegypti in large containers. 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 a...

Description
Summary:Here, we evaluated sweeping methods used to estimate the number of immature Aedes aegypti in large containers. 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. 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. Both sweeping methods are useful tools in epidemiological surveillance programs for the control of Aedes aegypti.
