Pest management: Four years experience in a commercial apple orchard
Abstract
Pest management in a 12-ha apple orchard from 1973 to 1976 resulted in a 50 percent reduction in the number of sprays that are normally applied to control insects and mites. Codling moth, <i>Laspeyresia pomonella</i> (L.), populations were monitored by sex pheromone traps and populations of other insects and mites were assessed by specific sampling techniques. Leafrollers were the most difficult pests to control and fruit injury was 1.5 to 2.0 percent in 3 of the 4 years. Mites were held below treatment levels by the predator, <i>Typhlodromus occidentalis</i> Nesbitt, except for the apple rust mite, <i>Aculus schlechtendali</i> (Nalepa) which required chemical control.References
