Seasonal Irregularities of the Codling Moth

Codling moth management and chemical ecology.

Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone. Pheromone-mediated mating disruption has become a commercially viable pest management technique and is used to control the codling moth, Cydia pomonella, a key insect pest of apple, on 160,000 ha worldwide. The codlin...

Classical Biological Control of Codling Moth: the California Experience

Codling moth is a notorious fruit-boring pest that has extended its original distribution from the natural apple forests of Central Asia to cover all apple growing regions of the world. Having been discovered in California as early as 1872, codling moth has continued to be the dominant pest of apple, pear and walnut production causing extensive damage in the absence of insecticide treatment. In...

Evaluation of Alternative Pheromone Dispensing Technologies for Codling Moth

Two new types of hand-applied pheromone dispensers, “meso-emitters”, were developed in collaboration with Suterra that increased the pheromone release rate per dispenser and decreased the number of dispensers per acre to only 12. Realized emission rates per dispenser only achieved 15-33% of the desired release rate. Further modifications are planned for 2007 to increase these release rates. In ...

Study of Factors Affecting Codling Moth Control by Mating Disruption

This year was the first year of a multiyear project to examine a. number of factors associated with the chemistry of codling moth mating disruption. A substantial portion of time and manpower was involved in building the apparatus required for the project and developing and troubleshooting methods required for the duration of the project. We are about three months behind schedule; we hope to ha...
