Larvicidal and Oviposition Activity of Commercial Essential Oils of Ledeb., (Blanco) Benth., L. and Their Combinations Against

is a vector responsible for the transmission of various arboviruses and is considered by the World Health Organization to be one of the main public health problems in the world. This study evaluated the larvicidal and oviposition activity of essential oils from , and and their formulations. Chromatographic analysis by GCMS identified a total of 28, 52 and 18 compounds for the oils of the species , and , respectively. The larvicidal bioassays showed an LC of 67.53 ppm, 92.45 ppm and 35.95 ppm, respectively, for (A), (J) and (P) as well as their binary (J + P, 39.50 ppm; A + P, 51.64 ppm) and ternary (A + J + P, 66.99 ppm) formulations. These oils and formulations also showed deterrent activity at the larvicidal concentrations tested (: OAI: -0.41; : OAI: -0.31; : OAI: -0.62; A + J + P: -0.30; A + P: -0.68; A + J: -0.29; and J + P: -0.30). The oils and their formulations are a potential larvicidal source for mitigating the proliferation of diseases by this vector.
