Codling 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.
