The Effectiveness of Evaporation and Spray Methods in Killing Aedes Aegypti Using Basil (Ocimum sanctum, Linn) Leaf Extract

Abstract

Dengue Hemorrhagic Fever (DHF) are acute febrile disease caused by virus dengue the into the human blood circulation through the bite Aedes aegypti. Prevention of the spread of dengue disease can be done by breaking the chain of transmission through vector control. The aim of this research was to determine the effectiveness of the method of evaporation and spray the deadly Aedes aegypti using basil leaf extract. This research is an experimental research. The sample in this study was 25 mosquito mosquitoes Aedes aegypti were presented with basil leaf extract concentration of 40%, 50% and 60%, with repetition as much as 3 times using the method of evaporation and spray for 135 minutes. The results showed that the higher concentration basil leaf extract more quickly and more mosquitoes died. In the evaporation method the number of dead mosquitoes were as many as 25 animals with LC₅₀ minutes 75 concentration of 60%. In the spray method the number of dead mosquitoes were as many as 25 animals with LC₅₀ minutes to 60 concentration of 50%. This is because the mosquitoes are exposed to extracts of basil leaves contain chemicals such as tannin, eugenol, flavonoids, tripenoid, and essential oil. The conclusion of this study is that the spray method at a concentration of 50% is a more effective method of killing the Aedes aegypti.It is expected that the community can utilize the evaporation method and spray using basil leaf extract because it is safe for the environment and humans.
