Aedes aegypti L. is a vector that cause Dengue Hemorrhagic Fever disease. Most of People used chemical insecticides to control the mosquito which have negative impacts, it cause resistance vector, so the experts look for another alternative with using biological control such as ethanol extract granules papaya seeds. Papaya seeds have larvasidal activity because it produces secondary metabolites like alkaloids and saponins. Serial concentrations of ethanol extract of papaya seed granules used in this study was 5 ppm, 10 ppm, 100 ppm, 1000 ppm, and 3000 ppm and performed 3 replications. Each treatment used 20 test larvae. Larva used as a test is the final larval instar III and early IV. the data obtained by the Aedes aegypti larvae mortality at 12 hours, 24 hours, 36 hours, and 48 hours. Data analysis using probit analysis. Based on the research and analysis of the data obtained it can be concluded LC50 24 hours and 48 hours was 15.572 ppm and 37.772 ppm. LC90 24 hours and 48 hours was 3.109 ppm and 9.970 ppm. LT50 and LT90 of 33.06 hours and 49.10 hours with concentrations of ethanol extract granules papaya seeds 10 ppm.It can be concluded that extract granules papaya seeds has insectisidal effect on Aedes aegypti larvae mortality.
