Abstract

The objective of this study was to evaluate the effect of ultrasound waves against dengue vector Aedes aegypti. The susceptibility tests were carried out to determine the egg hatchability and mortality rates of Aedes aegypti immatures. The ultrasonic bath device was used to test the effect of ultrasound waves on the dengue vector mosquito. Experiments were conducted at different series of time such as 30 S, 60 S, 90 S, 120 S, 150 S, 180 S and 200 S determine the percentage of mortality. The 100% larval mortality was observed in 180 seconds and 100% egg mortality observed in 150 seconds. The highest larval mortality was found in first instar larvae. These results suggest that ultrasound waves have more potential to kill the Aedes aegypti mosquitoes.
