The chemical composition of Lippia sidoides essential oils obtained by hydrodistillation was characterized and quantified by GC/MS and their insecticidal activity by fumigation test was assayed against Tenebrio molitor. Moreover, the toxicity of monoterpenes carvacrol, 1,8-cineol and thymol were also evaluated when applied alone or in binary (1:1) or tertiary (1:1:1) mixture. The essential oil of L. sidoides has as major constituents carvacrol (31.68%), ρ-cymene (19.58%), 1,8-cineole (9.26%) and ϒ-terpinene (9.21%), from a 21 compounds identified, being 92.53% of total. Both compounds have insecticidal activity against T. molitor, being the degree of toxicity of carvacrol > 1,8-cineole > L. sidoides essential oil > thymol, and its respectively LC50 at 24h were 5.53; 5.71; 8.04 and 14.71 µL/L air. When the different mixture of carvacrol, 1,8-cineole and thymol was assayed against T. molitor, the synergism among them was observed. For the mixture of carvacrol:1,8-cineole LC50 was 5.34 µL/L air; carvacrol:thymol 7.67 µL/L air; 1,8-cineole:thymol 7.51 µL/L air and carvacrol:1,8-cineole:thymol 6.34 µL/L air. Mainly, the monoterpene thymol had a synergic effect, which increased the toxicity of carvacrol and 1,8-cineole, both in binary mixture like carvacrol:thymol and 1,8-cineole:thymol.
