These maps will facilitate the discovery and exploitation of genes that can be used to control these pests. Second Year of Area-Wide Integrated Pest Management Study for Suppression of Insect Pests in Wheat was Completed. The cost and effectiveness of currently used pest management methods were determined for 13 elevators in Kansas and 15 elevators in Oklahoma. More than 6,000 one-gallon grain samples from the 30 million bushels of wheat stored at these elevators were examined for insects. Two thirds of these samples had no insects and most of the other samples had only a few insects.
Fumigation is the primary method of insect control.
Industry collaborators are using the information from the study to increase the effectiveness and reduce the cost of insect control. Subsequent studies will involve the implementation of additional integrated pest management tools and determination of their effectiveness at decreasing insect populations. This project is being conducted in cooperation with Kansas State University and Oklahoma State University. Efficacy of New Diatomaceous Earth Formulation. There was a slight increase in mortality of both species as the temperature increased.
