Insects develop resistance to engineered crops
Genetically modified crops containing two insecticidal proteins in a single plant efficiently kill insects. But when crops engineered
with just one of those toxins grow nearby, insects may more rapidly develop resistance to all the insect-killing plants, report Cornell University researchers.
