SUPPRESSION OF CODLING MOTH (LEPIDOPTERA: OLETHREUTIDAE) BY SEX PHEROMONE TRAPPING OF MALES

Abstract

AbstractThe intensive use of sex pheromone traps in an insecticide-free apple orchard from 1972 to 1974 reduced the codling moth population and level of fruit damage. The sex ratio of bait-trapped adults indicated that the male population was being reduced by the pheromone traps. In commercial orchards pheromone trapping of males suppressed codling moth damage to fruit but the amount of damage was above acceptable economic levels.
