Researchers at DuPont Pioneer have discovered a protein from a non-Bacillus thuringiensis (Bt) bacterium source.  Science Magazine published findings that show this protein is a promising alternative for controlling corn root worm in North American  and Europe.

“This research represents a breakthrough for addressing a major challenge in agriculture,” said Neal Gutterson, vice president, Research & Development, DuPont Pioneer. “We have discovered a non-Bt protein that demonstrates insecticidal control of western corn rootworm with a new and different mode of action than Bt proteins currently used in transgenic products. This protein could be a critical component for managing corn rootworm in future corn seed product offerings. The work also suggests that bacteria other than Bt are alternative sources of insecticidal proteins for insect control trait development.”

Another Pioneer study related to non-Bt insect control, recently published in Scientific Reports, shows how RNA interference (RNAi) can be applied to control corn rootworm feeding damage.

RNAi is a biologically occurring process that happens in the cells of plants, animals and people. By employing the RNAi process, a plant can protect itself by carrying instructions that precisely target specific proteins in pests.

“Growers need a next generation of solutions to help protect their crops. Our researchers are developing innovative, new modes for insect control to help meet future demands. Non-Bt proteins and RNA-based products highlight our efforts to identify alternative methods for effective control of insect feeding damage in agriculture,” Gutterson said.
