New Sprays for the Codling Moth

Creating point sources for codling moth (Lepidoptera: Tortricidae) with low-volume sprays of a microencapsulated sex pheromone formulation.

Studies were conducted to examine the deposition of microcapsules and the attractiveness of treated apple leaves, Malus domestica Borkhausen, for codling moth, Cydia pomonella L., after low-volume concentrated sprays [24.7 g (AI) in 12 liters of water/ha] of a microencapsulated (MEC) sex pheromone formulation (CheckMate CM-F). Nearly 30% of leaves collected from sprayed zones within tree canopi...

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...
