Insect Pest of Seedling Corn

John Van Duyn, North Carolina State University, Entomology Extension Specialist

Newly planted corn seeds, sprouting seeds, and seedlings can be attacked by insect pest within the soil, at the soil surface, or on aerial parts. There are numerous insects that will feed upon corn seeds and/or seedlings. Most of these potential pests do not commonly occur at damaging populations in corn fields. However, in some situations pests like wireworms, seed corn maggot, cutworm, billbugs, and stinkbugs occur in corn fields with enough regularity to warrant attention by growers. On well drained soils, conventional tillage corn grown in rotated fields will likely have a very low probability of damaging insect populations. These seedling pests do occur with greater frequency on poorly drained soil situation and on organic soils. Fields planted to corn following established grass (e.g. pasture or set -side field) will also have a mucher higher incidence of seedling insect pests. No-tillage corn, especially if planted into dense residue, also has a much increased incidence of seed and seedling feeding insect pests. Also, if corn is grown without rotation certain seedling pests, notably billbugs, may build-up to high populations.

In the following sections of this document the different seedling insect pests are discussed. Also, suggestions for managing seedling insects are provided. Review the index and click on subjects of interest.
