Genetically modified (GM) crops often require fewer pesticides compared with their conventional counterparts, thanks to their engineered ability to produce their own insecticides, a trait derived from the bacterium Bacillus thuringiensis (Bt). But insects such as the western corn rootworm are developing resistance to commonly used Bt insecticides, allowing them to happily munch their way through crop roots. Eager for a fresh combat strategy against corn rootworm, scientists at DuPont Pioneer began digging through the . . .
