Trait-delivered solutions for control of above-ground lepidopteran pests are largely limited to native resistance traits and utilization of Bt proteins expressed within tissues. Specific Bt proteins have been observed to vary widely with regard to activity against target pests. Among current Bt proteins registered in corn genetics, Cry1F has been found to deliver the most effective control of WBCW. As this insect pest continues to gain attention in corn growing regions of the U.S., it will be critical for producers utilizing trait-delivered insect control to choose seed products that contain Cry1F proteins. Cry1F is currently available in Herculex® I and Herculex® XTRA seed products and is being evaluated in SmartStaxÔ stacked-trait product concepts.
