Integrated Pest Management Options
Fumigant
Adults lay their eggs in maturing beans in the field with no apparent
visible damage. Heavily infested peas or beans can be fed to livestock.
The key to controlling stored-grain insects is prevention through
good sanitation and storage practices. See OMAFRA Publication 811,
Agronomy Guide for Field Crops, for more information on stored
grain insect management.
