Extract

Several authors (Charmillot and Baggiolini 1975; Proverbs et al. 1975; Roelofs et al. 1976; MacLellan 1976) have stated that mass-trapping male codling moths with sex pheromones did not provide economic control of this pest. MacLellan (1976), however, reported suppression of codling moth populations in unsprayed orchards 2-3 ha in size and Madsen et al. (1976) obtained similar results in orchards in which sprays were not applied specifically for codling moth control. In 1975 and 1976 similar studies were undertaken in three 0.5–0.75 ha plots (A, B, C) of mature apple trees at Vineland (Hagley 1970). Plots A and B had not received insecticide sprays from 1969 to 1974 and had relatively high codling moth infestation levels (Table I). Plot C had been on a pest management program since 1971.
