Abstract
The toxic and repellent activities of the volatile constituents of Aristolochia elegnas Mast, were evaluated against storage pest Corcyra cephalonica (Stainton). The chemical composition of the hydrodistilled essential oil isolated from leaves of A. elegnas L. growing in Egypt was determined qualitatively and quantitatively using GC and GC—MS. Experimentally, a total yield of 0.38 % NON of essential oil per 1kg fresh weight was gained which upon analysis yielded 40 compounds representing 98% of total essential oil. Bicyclogermacrene being the main component and the other major components identified were p-caryophyliene, limonene, germacrene D and isocaryophyllene. 3-caryophyllene oxide and &nerotdol were the prominent components of the oxygenated sesquiterpenes. The toxicity and repellency effect of the volatile constituents of A. elegnas was tested against Cl cephalonica where, a significant inhibitory effect was reported. The high toxicity of the volatile constituents of A. elegnas may be due to the presence of dialkyl phthalates and limonene, while, high repellency may be due to the presence of P-caryrophyllene oxide and nerolidol Therefore, they could be suitable for using as insecticidal and repellent agents against stored products pests in the food industry.
