description Northern Corn Rootworm Overview
Northern corn rootworm is the common name for Diabrotica barberi, a beetle in the leaf-beetle family Chrysomelidae. Its larvae live in soil and feed on the roots of maize, interfering with water and nutrient uptake and sometimes causing plants to lodge, while adults feed on above-ground corn tissues. The species is native to North America and is managed as an agricultural pest through practices such as crop rotation, insecticides, and, in some systems, rootworm-resistant maize.

help Northern Corn Rootworm FAQ
What is the scientific name of the northern corn rootworm?
The northern corn rootworm is Diabrotica barberi. It is a beetle in the leaf-beetle family Chrysomelidae.
What part of maize do northern corn rootworm larvae attack?
The larvae live in soil and feed on maize roots. Root injury can reduce water and nutrient uptake and may cause plants to lodge, meaning they fall over.
What do adult northern corn rootworms eat?
Adults feed on above-ground corn tissues, including leaves and reproductive parts. Their feeding is different from the root damage caused by the larvae.
Why can northern corn rootworm reduce corn yields?
Larval feeding damages the root system that supports water and nutrient uptake. Severe root injury can also cause lodging, which makes plants harder to harvest and can reduce production.
