In a 4-year areawide IPM project conducted in Kansas and Oklahoma, a decision support system for the management of insects in stored grain was developed and validated. Grain silos were sampled every six weeks using a vacuum probe sampler. Each bin was sampled to a depth of approximately 40 feet. The software and sampling technology provides grain managers with a method to determine which bins are at risk without having to move the grain from one bin to another; it also makes management recommendations and predicts which bins will be at risk in the future. This sampling and risk analysis program can save the elevators money and reduce fumigation; instead of using a calendar-based method of turning and fumigating all of the bins at a facility, managers only need to turn and fumigate bins that are predicted to have high insect densities.
