Population dynamics of stored-product insects at a rice mill in northeast Arkansas

The lesser grain borer (Rhyzopertha dominica), warehouse beetle (Trogoderma variabile), cigarette beetle (Lasioderma serricorne) and Indianmeal moth (Plodia interpunctella) are stored-product insects that can infest stored rice by boring, feeding and reproducing within the rice. The main objective of this study is to monitor the populations of these stored product insects at a rice facility in Northeast Arkansas. Pheromone-baited glue traps (N=99) were placed along building walls and along the perimeter of the facility from June 2008 to September 2009. The spatial and temporal distributions of stored-product insects collected at this facility will be discussed.
