Sex pheromone of Stenoma cecropia meyrick (Lepidoptera : Elachistidae)

Abstract : (Z,E)-9,11-tetradecadienal (Z9,E11–14: Ald; 11%), (Z,E)-9,11,13-tetradecatrienal (Z9,E11, 13–14: Ald; 67%), (Z,E)-9,11-tetradecadienyl acetate (Z9,E11–14: Ac, 5.5%), and (Z,E)-9,11,13-tetradecatrienyl acetate (Z9,E11,13–14: Ac; 16.5%) were identified in the extracts of female pheromone glands of Stenoma cecropia (Lepidoptera: Elachistidae). From electroantennograms and single sensillum recordings, receptors to Z9,E11,13–14:Ald and Z9,E11–14: Ald were found on male antenna. Behavioral data were obtained from olfactometric tests in the laboratory and field trapping experiments in Colombia. It appeared that a blend of Z9,E11,13–14:Ald (83%) and Z9,E11–14:Ald (17%) was attractive to males. These aldehydes are assumed to be components of the sex pheromone of S. cecropia, whereas the acetates found in gland extracts might be precursors of the pheromone.
