Abstract This experiment was conducted to assess the performance of Bacillus thuringiensis (Bt) transgenic corn hybrids (100- and 105-day RM) and comparable non-Bt hybrids against a natural ECB infestation in southwest Minnesota. Plots, each measuring 50 ft by 8 rows (30-inch row spacing), were established in Normania loam soil on 5 May at a rate ol 30,000 seeds per acre. Plots were arranged in a RCB with four replications. ECB injury assessments for first generations on 4 Aug included % shotholing from the center two rows of each plot and leaf injury ratings from 10 plants per plot. Tunnel length and number from both the first generation and univoltine generations were measured simultaneously from 10 plants per plot on 27 Aug. Measurements for second-generation ECB on 15-16 Oct included cumulative tunnel length and number, fall larvae, and ear and shank damage. Plots were harvested on 23 Oct and yields were corrected to 15.5% moisture.
