“Cutworm” is a common name for many caterpillars in the moth family Noctuidae. They are insects (not worms!) that chew, or cut through, plants above or below the soil line in the spring. One notable exception is the western bean cutworm, which occurs later in the season and targets reproductive tissues rather than cutting stems.

The Iowa State University Extension and Outreach Crops Team is seeking sponsors for our upcoming winter programs. These programs include the Integrated Crop Management Conference (ICM), the Crop Advantage Series, Planter U, and CropsTV. Each year the Crops Team reaches over 2,000 contacts through events like these. 

The hot-and-cold temperatures this spring have delayed alfalfa weevil development throughout the state. We visited a field in Henry County, IA this week and noticed all sizes of larvae plus pupae. Take a sweep net to the field to see what's happening in your alfalfa fields. Also, note aphids and other potential pests. Sometimes, mechanical control (mowing) may be the most economical management tool.
