Western Corn Rootworm is a major corn pest in the midwest and eastern North America
It causes significant damage by:
- Larvae feed on roots (spring and early summer) causing lodging and limits growth and tonnage.
- Adults feed on silks (July-Sept) which limits pollination and cob development
- Adults fly and search for pollen—will damage flower crops (i.e. dahlias)
First detection in B.C. was confirmed August 10, 2016 in Sumas Prairie.
