Monitoring Codling Moth Populations in British Columbia Apple Orchards

In British Columbia apple orchards, a program of pest management is well established and administered by professional managers holding a master’s degree in pestology. The key to the management program is a monitoring system for codling moth, Laspeyresia pomonella (L.), based upon male captures in sex pheromone traps. The monitoring program has been developed for conditions in British Columbia orchards and it should be emphasized that although principles have application elsewhere, details of a monitoring system must be determined for each area.
