Field corn production in Mississippi can be affected by a complex of soil insect pests, including southern corn rootworm, wireworms, seed corn maggot, and white grubs. These pests are usually present in corn fields at planting, and while the infestations are generally sporadic, large infestations can severely reduce yield if not managed. In addition to sanitation and cleaning, effective management involves grain distribution and aeration and stored grain insect management.
