ABSTRACT
Aedes aegypti is the main vector of dengue virus transmission for dengue fever. The effective method to reduce dengue cases is to used a biological insecticides such as Gynura pseudochina at larval stage of A.aegypti. The research was performed to find out the Gy. pseudochina leafs extracts potential as an Ae. aegypti larvacide. This experimental research conducted with completely randomized design that used seven different concentrations (0%, 5%, 6%, 7%, 8%, 9%, 10%). As the result, there were mean differences in the Ae. aegypti larvae mortality at each concentration of Gy. pseudochina group, except for the concentration 5% to 6% and 9% to 10%. After 24 hours treatment, LC50 was gained at 6.271% extract concentration with a lower limit at 5.322% and upper limit at 7.005%. This result shows, Gy. pseudochina leafs extracts has proved to be a potential Ae. aegypti larvacide.
