The seedcorn maggot, Delia platura (Meigen), is an occasional pest of agronomic crops in Missouri. This insect is widely distributed throughout the temperature zones of the world. It was not discovered in the United States until 1855. This insect feeds on the seeds and roots of many different grain (e.g., corn, soybeans) and vegetable (peas, watermelons) crops.
