Rootworm behavior and resistance in Bt cornfields

Joseph L. Spencer, Sarah A. Hughson

Research output: Contribution to conferencePaperpeer-review


The western corn rootworm (Diabrotica virgifera virgifera LeConte, WCR) is the most economically important U.S. corn pest (Gray et al. 2009). Together with the northern corn rootworm (Diabrotica barberi Smith and Lawrence, NCR), it was estimated that these pests annually cost producers $1 billion in yield losses and control costs (Metcalf 1986). Today the cost is thought to be much greater (Dun et al. 2010; Tinsley et al. 2013).
