摘要：A variant of the western corn rootworm (CRW) has adapted to the widely used cultural practice of crop rotation. This study analyzed the economic value of control options controlling the western CRW variant across Indiana. The options analyzed are soil insecticides, seed-applied insecticides, the recently commercialized genetically modified corn to resist CRW (CRW corn), or not controlling the western CRW variant. The results suggest that the economic value of CRW corn may exceed that of the alternative options for corn producers with high western CRW variant pressure, irrespective of producers' risk aversion levels and have the highest economic value for risk-averse producers in the moderate western CRW variant pressure region of Indiana.
