Kansas and Nebraska Foundation Seed Facilities currently rely on a grain protectant that will no longer be available at the end of 2004 to protect stored wheat from insect pests. Our objectives were to determine when peak insect activity occurred and how the insects entered the facilities in order to develop an integrated pest management program. We collected weather data and monitored seasonal flight activity of the lesser grain borer during the 2003 and 2004 storage seasons. Pheromone baited Lindgren funnel traps were positioned in cardinal directions at distances of 0, 50, 100, and 150 m away from the seed storage warehouses and checked weekly. Results show that insect response to the commercial pheromone decreased with each week in the field and there was not a clear trend to relate trap distance from the warehouse to quantity of insects captured. Insect captures near grain bins were similar to other parts of the properties but few insects were captured in flight traps placed inside the warehouses. Numerous lesser grain borers as well as other stored grain species were detected on unbaited sticky traps placed near gaps around overhead doors leading us to believe that this is an important entry route.
