AbstractThe intensive use of sex pheromone traps in an insecticide-free apple orchard from 1972 to 1974 reduced the codling moth population and level of fruit damage. The sex ratio of bait-trapped adults indicated that the male population was being reduced by the pheromone traps. In commercial orchards pheromone trapping of males suppressed codling moth damage to fruit but the amount of damage was above acceptable economic levels.

Okanagan Valley

AbstractSex pheromone traps to control codling moth by male removal was evaluated in three orchards in the Okanagan Valley. The program was successful in only one of the three orchards. This orchard is completely isolated and codling moth control has been obtained for 5 years. In a second orchard, codling moth populations were reduced by sprays prior to the male removal program. The program was successful in 1977, as the per cent injured fruit was only 0.6. In 1978, the codling moth capture rose sharply and at harvest the per cent injured fruit was 8.0. There was a high infestation in the third orchard when the program was initiated, and in 1976, the per cent injured fruit dropped to 10.4% from 60.0 in 1975. The per cent fruit injured by codling moth rose to 37.4 in 1977 and to 60.2 in 1978 under the male removal program. Our data show that this method of control is effective only under special circumstances, where codling moth populations are low and where isolation precludes reinfestation.

Laspeyresia Pomonella

AbstractCodling moth, Laspeyresia pomonella (L.), injury in a 14-ha apple orchard gradually increased in 1973 and 1974 despite the presence of 480 sex pheromone traps (1 mg trans-8, trans-10, dodecadien-1-ol per trap). Percentage injured fruit at harvest was 0.00075, 0.0062, and 0,033 in 1972, 1973, and 1974, respectively. Numbers of wild male moths trapped increased from 3e in 1973 to 64 in 1974.

Laspeyresia Pomonella

AbstractCodling moth populations in six orchards in the Okanagan and Similkameen valleys of British Columbia were monitored for 2 seasons with traps baited with trans-8, trans-10, dodecadien-1-ol, the sex pheromone of the codling moth, Laspeyresia pomonella (L.). Sprays were applied if traps within the orchard captured two or more moths per trap per week during 2 consecutive weeks. Traps installed in neighboring orchards minimized male moth influx. A 43.1% reduction in the number of required cover sprays for codling moth control was obtained over a 2-year period compared with a standard three spray program. Fruit injured by codling moth in monitored orchards varied, but was less than 1% in all but one orchard.
