Abstract
In 1992, at the Southern Oregon Experiment Station, a program combining mating disruption and horticultural spray oil was compared with programs using each tactic by itself on the Bartlett cultivar.
When used singly, both mating disruption and horticultural spray oil provided substantial first generation codling moth suppression; but, by harvest, codling moth infestation had increased to unacceptable levels, 12.8% and 24.3% respectively.
However, by combining these two tactics codling moth control was significantly increased.
Infestation levels in the combination program ranged from 0.7% to 5.8%. The combined mating disruption and horticultural spray oil program was non-disruptive (i.e. significant levels of predators were observed), and control of secondary pests was also achieved.
