Stored product insects in a flour mill: population dynamics, spatial distribution, dispersal behavior and implications for pest management

James F. Campbell, USDA-ARS, Grain Marketing and Production Research Center, 1515 College Ave, Manhattan, KS and Terry Arbogast, USDA-ARS, CMAVE, P. O. Box 14565, Gainesville, FL.

In this multiple year study of stored-product insect populations in a flour mill, red flour beetle, warehouse beetle, and Indianmeal moth populations were monitored within the mill, using pheromone traps and product sampling, and outside the mill, using pheromone traps around the perimeter of the building. Mark-recapture was also used to evaluate the potential for outside and inside populations to be interconnected. With this data set, questions about seasonal population dynamics and the spatial distribution of trap captures, the ability of pheromone monitoring to predict product infestation, and the efficacy of structural fumigation will be addressed.

Species 1: Coleoptera Tenebrionidae Tribolium castaneum (red flour beetle)
Species 2: Coleoptera Dermestidae Trogoderma variabile (warehouse beetle)
Species 3: Lepidoptera Pyralidae Plodia interpunctella (Indian meal moth)
Keywords: fumigation
