Electrophysiological Response of Chilo partellus to Maize Volatiles

Abstract

In the present study maize plant volatiles were collected by solvent assisted extraction (SAE) using hexane and dichloromethane (DCM) solvents. The evaluation of volatile extracts against male individuals of Chilo partellus through Gas Chromatography-Electroantennogram Detector (GC-EAD) revealed the presence bioactive compounds. The identification of these bioactive compounds through Gas Chromatography-Mass Spectroscopy (GC-MS) revealed that male individuals of C. partellus elicited response to 20 maize volatile compounds, out of which benzyl alcohol and myristic acid were detected in both the solvent extracts. These bioactive volatile compounds can be further explored for developing lures either of plant volatiles or in combination with pheromone.
