- Abstract
The dengue virus is transmitted by Aedes aegypti. Several plants are used to control this mosquito In the present study the chemical composition of the essential oils of Ruta chalepensis, Zanthoxylum fagara and Thymus m i gai is were analyzed, and their activities against larvae of two A. aegypti populations were evaluated The major compounds found in T. vulgaris were thymol and ocymene at 39.8% and 30.5%, respectively, with the major components being oxygenated monoterpenes and monoterpene hydrocarbons at 55.5% and 40.4%, respectively. For Z jagara, the major compounds were sylvestrene and E-caryophyllene at 25.3% and 23.6%, respectively, with the major components being sesquiterpene and monoterpene hydrocarbons at 51.1% and 37.5%, respectively. Ketones were the predominant group of compounds found in R. chalepensis, with the major components being 2-undecanone and 2-nonanona at 43.7/o and 35.4%, respectively. Essential oils from T. vulgaris, Z.fagara and R. chalepensis showed activity against larvae of the A. aegypti New Orleans strain, producing median lethal concentrations (LC50) of 2.14, 27.57 and T69pg/mL, respectively, at 24 h. LC50 values produced against larvae of a local A. aegypti population in Nuevo Leon Mexico, were 25.37, 60.42 and 20.13pg/mL, respectively, at 24 h.
