EVALUATING LARVICIDAL EFFICACY OF COMMERCIAL CLOVE OIL (SYZYGIUM AROMATICUM) AGAINST AEDES AEGYPTI FOR DENGUE CONTROL

Abstract

Essential oils, as natural products, offer a promising alternative for controlling the
dengue vector population, specifically targeting the immature stages of Aedes aegypti that
develop in water containers. Previous research has shown that clove oil is effective against a
variety of insects, including rhinoceros beetles, red flour beetles, and mosquitoes. This study
evaluated the larvicidal activity of commercial clove essential oil (Syzygium aromaticum)
against Aedes aegypti, a critical vector of dengue, over various exposure durations: 12, 18, 24,
and 48 hours. The LC25 values recorded at 12, 18, 24, and 48 hours post-exposure were 0.05,
0.05, 0.05, and 0.04 ppm, respectively. Similarly, LC50 values were 0.07, 0.06, 0.06, and 0.06
ppm, respectively, for the same time points. The LC90 values at these time intervals were 0.11,
0.10, 0.10, and 0.12 ppm, respectively. These results contribute to the existing body of
knowledge by confirming the potential of clove essential oil as an alternative approach for
controlling the dengue vector
