Mating disruption is a commercially available management tactic for pyralid moths that are pests of stored products. However, evaluations of efficacy have had limited replication which limits the ability to draw conclusions about effectiveness or impact of different variables on efficacy. We evaluated mating disruption of Plodia interpunctella in 33 retail pet supply stores, and the impact of factors such as insect density and application rate on efficacy. The objective of the project reported here was to evaluate how well mating disruption can suppress moth populations in retail pet stores, by assessing treatments under ‘real world’ conditions found in commercial operations. Data set included the characteristics of the stores including volume and geographic location, the mating disruption treatment types including the number and location of dispensers, and the captures of moths in pheromone baited traps over time before applying the mating disruption treatment and during the mating disruption treatment.
