Resumo: | 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. |

Além disso, a toxicidade dos monoterpenos carvacrol, 1,8-cineol e timol, também foi avaliada quando esses compostos foram aplicados isoladamente, ou em misturas binárias (1:1), ou terciárias (1:1:1). O óleo essencial de L. sidoides tem como principais constituintes o carvacrol (31,68%), ρ-cimeno (19,58%), 1,8-cineol (9,26%) e ϒ-terpineno (9,21%), em 21 compostos identificados, sendo 92,53% do total. Ambos os compostos possuem atividade inseticida contra T. molitor, seguindo a ordem de toxicidade: carvacrol > 1,8-cineol > óleo essencial de L. sidoides > timol; sendo suas respectivas CL50 à 24 h de 5,53; 5,71; 8,04 e 14,71 µL/L ar. Quando as diferentes misturas de carvacrol, 1,8-cineol e timol foram avaliadas contra T. molitor, verificou-se o efeito sinérgico. Para a mistura de carvacrol:1,8-cineol a CL50 foi de 5,34 µL/L ar; carvacrol:timol de 7,67 µL/L ar; 1,8-cineol:timol de 7,51 µL/L ar e carvacrol:1,8-cineol:timol de 6,34 µL/L ar. Principalmente o monoterpeno timol teve efeito sinérgico, aumentando a toxicidade de carvacrol e 1,8-cineol quando em misturas binárias, tais como carvacrol:timol e 1,8-cineol:timol.Editora da Universidade Federal de Lavras2011-08-012015-04-30T13:36:12Z2015-04-30T13:36:12Z2015-04-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articletext/htmlhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-70542011000400004LIMA, R.
