European corn borer (ECB) is a pest of several crops including field, sweet and popcorn. Once considered a key pest of field corn, populations of ECB have declined since the widespread adoption of commercial corn hybrids that express above ground traits. However, in recent years populations of ECB have increased. Likely because of growers using more conventional corn hybrids and because of several other non-traited host crops being planted.
