Insect pest monitoring program in subsistence warehouses can detect pest problems in early infestation stages. Temporal and spatial distributions of pests produced by monitoring allows facility managers and pest control operators to visualize pest problems and evaluate effectiveness of cleaning, sanitation and pest management practices. Pheromone-based insect monitoring traps were placed to study temporal and spatial distribution of Lepidopteran and Coleopteran stored product pests in two central distribution centers of United States Military Forces in the Republic of Korea, from March to December 2008. The two distribution centers receive store and issue subsistence and they are located in two different cities, Seoul and Taegu. As a result, three pests, Plodia inter punctella Hübner (Indian meal moth), Lasioderma serricorne F. (cigarette beetle), and Trogoderma variabile Ballion (warehouse beetle), were detected on the traps. P. interpunctella was most abundant, followed by L. serricorne and T. variabile. Different phenologies and spatial distribution of each species were seen from the two warehouses, that were related with internal temperature of the two warehouses and food availability. The program benefited to lead a better understandings for existence and extent of local pest problems in the two subsistence distribution centers, and also helped to find effective pest management periods and locations.
