Chemical composition and insecticide activity of lemon verbena essential oil
Essential oil extracted from the leaves of Lemon verbena, <em>Lippia citriodora</em> Kunth<em> </em>(Verbenaceae) was tested for fumigant toxicity in the laboratory against two stored-product insects <em>Tribolium confusum</em> Jacquelin du Val and <em>Callosobruchus maculatus </em>(F.). The chemical composition of the isolated oil was examined by GC-MS. The major compounds were citral (11.3%), limonene (10.6%), neral (7.9%), 4-phenyl undecan-4-ol (7.7%), α-curcumene (6.5%), α-cedrol (4.5%) and caryophyllene oxide (4.5%). Furthermore, lesser amounts of the other components include carveol (3.7%), linalool (3.5%), α-pinene (3.2%), caryophyllene (2.8%) and geranyl acetat (1.8%) were existed in the essential oil. In the fumigant toxicity set at 27 ± 1 °C and 65 ± 5% R. H., darkness condition and 24 h exposure time, considerable differences in mortality of insect to essential oil vapor were observed.<em> C</em>. <em>maculatus</em> (LC50 = 10.2 µl/l air) was significantly more susceptible than <em>T. confusum</em> (LC50 = 497.8 µl/l air). These results suggested that essential oil of <em>L. citriodora</em> could be used as a potential control agent against stored-product insects.
