Toxic Test of Lavender Leaf (Lavandula angustifolia) Ethanol Extract as Biolarvicide for Aedes aegypti Mosquitoes Vectors of Dengue Hemorrhagic Fever

Toxic test of ethanolic extract lavender (Lavandula angustifolia) leaf on mortality Aedes aegypti mosquito larvae as vector dengue hemorrhagic fever has been completed. The aim the study was to determine effective concentration ethanol against and LC50 mosquitoes for 24 hours. This used a completely randomized design with 5 treatments, namely: 10ppm; 50ppm; 100ppm; 500ppm 1000ppm 1 control group 3 replications. results were analyzed using one-way analysis variance. continued BNT at significance level 0.05. showed that leaves toxic Aeders mosquito, which indicated by increasing number larval mortality. Based results, 500 ppm able kill 100% mosquitoes, 50% 87.0285 ppm. potential be developed biolarvicide fever.
