| Abstract: | Essential oils (EOs) from leaves of Virola calophylla, Virola multinervia, and Virola pavonis (Myristicaceae) were obtained by hydrodistillation, analyzed by gas chromatography coupled with mass spectrometry (GC/MS), and investigated for their larvicidal activity against Aedes aegypti larvae. The major compounds identified in the EOs were β-caryophyllene (54.8 % in V. calophylla and 55.7 % in V. multinervia) and β-selinene (60.5 % in V. pavonis). The EOs showed low larvicidal activity, LC50 =179.6 μg/mL for the V. calophylla EO, followed by those of the V. pavonis LC50 = 185.1 μg/mL and V. multinervia LC50 = 200.5 μg/mL. The β-selinene-rich fraction (78.6 %) isolated from V. pavonis EO showed no larvicidal activity (LC50> 350 μg/ mL). These results represent the first report about the chemical composition and the larvicidal evaluation of the EOs from those Amazonian Virola species. |
