Turkish Journal of BiologyA Theoretical study on the Sex-pheromones of the Rice Moth, Corcyra cephalonica Stainton
Middle East Technical University Department of Chemistry Ankara-TURKEY
Abstract: Molecular orbital calculations (AM1 type) were performed on the geometry optimized structures of various farnesal isomers and methyl esters of farnesoic acids. It has been found that the major component, E, E-farnesal, of the sex-pheromone for the rice moth, Corcyra cephalonica Stainton is chemically the most exothermic and stable of all the farnesal isomers. Then, the resem-blance of molecular shapes was detrmined in order to design more stable sex-attractants.
Key Words: Corcyra cephalonica, Pyralidae, Galleriinae, molecular orbital calculations, pheromones.
