The study on the effect of ultrasonic device against the dengue mosquito, Aedes aegypti adults was done in Peet Grady chamber. Three replications of tests were performed based on 24 hours expositions. 50 female mosquitoes on each replication were introduced by ultrasonic device (type ICE) in Peet Grady Chamber, and the other 50 females were put in other Peet Grady Chamber without the device. Observation and counts on knock down mosquitos (mortality rate) were done every one hour to six hours, then 24 hour after exposure. The result showed that during the first hour observation, 2.67% of mosquitoes were knockdown (died) by ultrasonic device (ICE type).In the long run (one to six hours) observation, 3.33 to 10% of the mosquitoes were died, however, after 24 hours exposure 74% of the mosquitoes died. On the control groups, all of the mosquitoes (100%) were still alive on the six hour observations, and after 24 hour observations only 7.33% mosquioes died. Based on the observation, the ultrasonic device (ICE type)affected the mosquitoes after 24 hours observations by giving them knock down efect and finally died (74%).
KEY WORD: Aedes aegypti, knockdown effect, mosquito, ultrasonic.
