During 2011-2013, greater than expected root injury by western corn rootworm larvae to hybrids expressing the Cry3Bb1 protein has been reported in some Nebraska fields.
An upside to the extraordinary cold temperatures South Dakota experienced this winter is the negative impact the extreme temperatures may have had on egg mortality of corn rootworms (CRW).
With the addition of three more counties, a total of five Illinois counties have now reported confirmed cases of field-evolved resistance to Bt corn (Cry3Bb1 protein) by western corn rootworm, and a University of Illinois entomologist said now is the time to move forward aggressively with integrated pest management (IPM) strategies.

Corn traders seemed disappointed by Thursday’s Export Sales report. Potential improvements in spring planting conditions have been weighing corn futures. Traders also seemed less than impressed by the weekly USDA Export Sales report, which stated last week’s result toward the lower end of the forecast range. May corn slid 2.75 cents to $4.9475/bushel in late Thursday trading, while December lost 2.25 to $4.9675.
