Technical Abstract: Understanding and eliminating routes of pest immigration into grain storage and processing facilities will provide new opportunities for targeted pest management. Stored-product Coleoptera were captured on unbaited rodent glue boards positioned on the floor and along the sides of overhead doors in Foundation Seed Warehouses located at Kansas and Nebraska. Traps were examined and replaced weekly from May through October 2004. Principal species recovered included the lesser grain borer, foreign grain beetle, rusty grain beetle, warehouses beetle, hairy fungus beetle, rice weevil and red flour beetle. The most economically important species, lesser grain borer, was always found at or near ground level suggesting that pest management efforts, such as residual spray applications, should be focused in these areas. The number of lesser grain borers captured on the unbaited glue boards correlated with captures in pheromone baited flight traps located outside the facilities. These data suggest that outdoor pheromone traps provide a strong indicator of infestation potential.
