As mentioned in last week's newsletter, the bean leaf beetle population in Ames is larger this spring than in the past three years. Larger insect populations usually cause greater amounts of plant injury, which can be very obvious as you are scouting young soybeans. Feeding injury from bean leaf beetles is easy to recognize if you know their characteristic feeding patterns.
