Commercially available pheromone lures are widely used in Integrated Pest Management (IPM) programs. Commodity warehouses commonly use a low density grid (one trap per 10,000 ft2) of high dose pheromone lures in traps to monitor insect population levels. In this study, large numbers (one trap per 1,500 ft2) of low dose pheromone lures in traps were placed in several commodity warehouses that had a history of Indian Meal Moth (Plodia interpunctella) infestation. Traps were exposed for seven to ten day periods or pulses. These pulses were repeated when moth counts in the monitoring traps began rising. Population levels, as measured by pheromone monitoring, did not increase at the rate of increase in previous years. Because the population did not increase when this program was used, fewer insecticide applications were required than in previous years.
