Abstract

The purpose of this study was to test the effectiveness of a combination of Curcuma aeruginosa Roxb rhizome extract and patchouli oil as a larvicide and repellant against Aedes aegypti mosquitoes. The method used was experimental, based on procedures recommended by the World Health Organization Pesticides Evaluation Scheme (WHOPES, 2009) The concentration ratio of C. aeruginosa Roxb extract and patchouli oil used was 0%:100%; 25%:75%; 50%:50%; 75%:25%; and 100%:0%. For larvicidal and repellant tests, 30 Ae. aegypti larvae and 30 adult female mosquitoes were used. Data were analyzed with the Shapiro-Wilk test, then analyzed with ANOVA, and continued with the posthoc test. The results showed that the combination of C. aeruginosa extract and patchouli oil was effective as a larvicide and repellant against Ae. aegypti. The most effective concentration of the combination of C. aeruginosa rhizome extract and patchouli oil as a larvicide on Ae. aegypti mosquitoes are 75%:25% and as a repellant at a combination of concentrations of 50%:50% and 75%:25%.
