The Midwest produces most of the food and feed grains and oilseeds grown in the US. as well as a substantial proportion of a variety of other crops, but corn accounts for at least 75% of insecticide use in the region. The total amount of insecticides used on crops could be greatly reduced if economic losses from insects could be predicted accurately. We will examine the current status of chemical controls for insects of economic importance to this region, indicating some areas where new developments are needed or are likely to occur.
