Field Crop Insects is a publication that is a cooperative effort between the Iowa Soybean Association and the College of Agriculture and Life Sciences and Iowa State University Extension and Outreach. The publication contains descriptions and images of many pest insects as well as information on insect life cycle, damage, scouting and management options. Correct recognition and identification of insect pests is an important first step to making a proper management decision regarding any insect species found in soybean and corn. This website provides access to information and resources to complement Field Crop Insects.
