Toksisitas Tanaman Empon-empon (Suku Zingiberaceae) terhadap Mortalitas Larva Nyamuk Culex sp.

Abstract: Culex sp. is a species mosquito as a main vector that caused Filariasis disease. Based on these problems, one alternative used botanical insecticides Zingiberaceae rhizome namely ginger, lesser galangale, turmeric, fingerroot. Zingiberaceae has characteristic is contained essential oil of rhizomes and potentially as larvicides. The larvae are used as a treatment is 20  larvae with 3 replications third instar larvae - IV early. Data larval mortality was observed every 24 hours and 48 hours. Data analysis was used probit analysis. Based on research and analysis conducted, it was obtained for the ginger rhizome, LC₅₀ ginger rhizome is 1003.113 ppm, 822.78 ppm. LC₉₀ ginger rhizome is 4024.858 ppm and 3250.852 ppm. While LC₅₀ lesser galangale rhizome is 360.488 ppm, 275.049 ppm. LC₉₀ lesser galangale rhizome is 1655.451 ppm, 1070.974 ppm. LC₅₀ turmeric rhizome is 479.091 ppm, 374.598 ppm. LC₉₀ turmeric rhizome is  2504.981 ppm and 1476.845 ppm. While LC₅₀ fingerroot rhizome is 1377.051 ppm, 1015.707 ppm. LC₉₀ fingerroot rhizome is 5687.984 ppm and 3879.824 ppm. It can be concluded that the Zingiberaceae are most effective as larvicides starting lesser galangale rhizome, turmeric rhizome, ginger rhizome, fingerroot  rhizome
