Moths emerge early in spring and lay eggs on or near the host's leaves or stems. Since this weevil migrates by crawling or flying, crop rotation and sanitation measures are valuable in controlling this pest. University of Alaska Fairbanks, Cooperative Extension Service.

One form of cultural control is the destruction of weeds around the field in fall or early spring. Chemical control consists of applying foliar insecticides or using a granular insecticide in furrow at planting. In addition, handle seeds carefully to avoid cracking the seed coat; a cracked seed coat provides entry points for maggots and fungus. Adult flies emerge from puparia at night or early in the morning and push themselves up to the soil surface. Violets, chickweed, pokeweed, wild mustard, hairy vetch, red clover, Carolina geranium, and blackberry are common hosts from which infestations spread to crops nearby. D. Nymph.
