EFEKTIVITAS EKSTRAK ETANOL DAUN MAHONI (Swietenia mahagoni (L.) Jacq.) TERHADAP LARVA Aedes aegypti L.

Abstract

The aim of the research were to evaluate the efficacy of botanical insecticide of S. mahagoni leaves extracts against larvae of Ae. aegypti, based on concentration of the leaves S. mahagoni extract, and in additional to determine secondary metabolites compounds of S. mahagoni leaves extract. The extraction of S. mahagoni leaves was done by using ethanol solvents and than was analyzed by using Thin Layer Chromatography. The result indicated that ethanolic extract of S. mahagoni leaf contained alkaloid, tannin, saponin, terpenoid, and flavonoid compounds. The value of LC₅₀ and LC₉₀ calculation showed that LC₅₀ of ethanolic extract over second and third instar larvae respectively were 488 ppm and 644 ppm. However the value of LC₉₀ of both instar larvae were 732 ppm and 797 ppm. Based on the above result, it can be concluded that ethanolic extract of S. mahagoni leaf was effective against larvae of Ae .aegypti.

Key words: Ae. aegypti, S. mahagoni, botanical insecticide
