predicting the emergence of the codling moth, cydia pomonella (lepidoptera: tortricidae), on a degree-day scale in north america.codling moth, cydia pomonella (l.) (lepidoptera: tortricidae), is a major pest of apple, pear and walnut production in north america. management programs are based on preventing larval entry into the fruit or nut and are typically timed by heat-driven models that are synchronized to field populations by first capture of overwintering moths in pheromone traps. unfortunately, trap capture is affected by a range of environmental parameters as well as by the use of mating disruption, which makes det ...201323424021
an attempt to increase efficacy of moth mating disruption by co-releasing pheromones with kairomones and to understand possible underlying mechanisms of this technique.pheromone-based mating disruption is used worldwide for management of the internal fruit feeding codling moth, cydia pomonella (l.). there has been recent interest in the potential of improving mating disruption of c. pomonella, and potentially other insect species in general, by broadcasting combinations of pheromone and attractive host-plant kairomones. given that such kairomones are attractive by themselves (often to both sexes), and also enhance male moth response to their pheromone, it is p ...201323339797
