Behavioral observations of codling moth, Cydia pomonella, in orchards permeated with synthetic pheromone

摘要: Mating disruption of codling moth, Cydia pomonella, was studied in apple orchards treated with the main pheromone compound codlemone, (E,E)-8,10-dodecadienol, and a blend codlemone acetate, (E,E)-8,10-dodecadienyl strong antagonist. Codlemone alone pheromone/antagonist-blend had similar effect on behavior males emerging into air-permeated orchards. Male flights within tree canopy upwind orientation along rows were strongly enhanced by both formulations, compared to untreated plots. However, codlemone/codlemone acetate-blend increased rate cross-wind downwind orchard, alone. The major difference between these two formulations that from nearby, attracted towards but not treatments acetate. Additional tests done an equilibrium its geometric isomers. Aerial concentrations recorded field electroantennogram technique.
