Abstract INTRODUCTION: The ability of Vitex trifolia and Vitex negundo essential oils to kill Aedes aegypti and Culex quinquefasciatus larvae was evaluated.METHODS: Hair brush cleaner The larvae were treated with their respective essential oils at 50-125 ppm concentration.RESULTS: LC50 and LC90 for V.
trifolia against Ae.aegypti and C.quinquefasciatus, and Textiles those for V.
negundo against Ae.aegypti were 57.7+0.
4, 77.9+0.9 ppm and 55.
17+3.14, 78.28+2.
23 ppm, and 50.86+0.9, 73.
12+1.3 ppm, respectively.Eucalyptol and caryophyllene were the major components in Vitex trifolia and Vitex negundo essential oil, respectively.
