Spraying for the Codling Moth

Optimizing use of codling moth granulovirus: effects of application rate and spraying frequency on control of codling moth larvae in Pacific Northwest apple orchards.

New formulations of the codling moth, Cydia pomonella (L.), granulovirus (CpGV) [family Baculoviridae, genus Granulovirus] are commercially available in North America. In field tests on apple (Malus sp. 'Delicious'), we compared different application strategies for CpGV (Cyd-X, Certis USA, Clovis, CA) used in full-season programs against high pest populations. In replicated single tree plots, t...

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...

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 ...

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...
