Interpretive Summary: Scientific cost of our dependence on insecticides has increased over the years and so have the spraying times for codling moth in the orchards. Money can be saved from the biggest insecticide expenditures, secondary pests. In order to reduce costs to the minimum, we need to maximize biological control in the orchard. Secondary pest levels are based on leaves, buds, and shoots collected from orchards. Mating disruption in orchards has helped reduce secondary pests. Conventional blocks are still having problems reducing secondary pests. Due to the loss of regulations from FQPA it is important to change tactics used in pear pest management.

Technical Abstract: For at least 70 years, control of codling moth with insecticides has structured pear pest management in the West. The Yakima Valley Pew/EPA pear IPM project (PEW), the codling moth area-wide management project (CAMP), and burgeoning independent use of mating disruption (MD) have shown there is a different and better way to manage this pest. Our challenge for the future is to build upon this innovation and create a truly integrated strategy for pear pest management. To do this we must rebuild our existing IPM strategy from the bottom up, by shifting our research priorities from efficacy of control measures to better understanding of pest and natural enemy biology.
