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.
