CODLING MOTH (LEPIDOPTERA, TORTRICIDAE) CONTROL BY DISSEMINATION OF SYNTHETIC FEMALE SEX-PHEROMONE

Permeation of a synthetic pheromone mixture through an isolated Asian pear orchard provided excellent control of the codling moth in the Sacramento Valley of California during a 2-yr period. The synthetic pheromone mixture was applied in 1,050 plastic twist-tie dispensers and at the rate of 100 g codlemone, 50 g dodecanol, and 10 g of tetradecanol per hectare. Female codling moth antennae give electroantennogram responses to these compounds.
