If you read the bean leaf beetle prediction in the May 1 ICM newsletter, you'll know that winter mortality of this soybean pest is expected to be at a 12-year low. The result will be that we should have more bean leaf beetles this spring than during an average year. In fact, our predictions, based on summer population increases during the last several years coupled with the mild winter, are for the populations to be very large. Sweep samples taken from alfalfa fields in Ames on May 2 indicate that the beetles are extremely abundant; they should move to soybeans as soon as the plants germinate.
