Abstract

Stalk borer is a pest to corn and occasionally soybeans. Damage is usually limited to the first few rows adjacent to grassy fencerows, terrace backslopes, and road ditches, but occasionally the damage is fieldwide. Stalk borers have one generation per year. Moths are attracted to leaves and stems of grasses and broadleaf weeds, starting in late August through mid-October. The eggs overwinter and hatch the following spring starting when around 500 base-41 degree days has accumulated. These larvae feed in the spring growth of the grasses, but eventually grow too large to stay inside the small grass stems, forcing them to move to larger plants.
