The corn-borer is a nightmare insect, specifically for farmers specializing in growing maize. Thanks to genetic modifications to regular corn, corn that may be in your refrigerator right now, the corn-borer is no longer a big issue. This genetically altered crop produces the Bt protein, which acts as an insecticide against the crop’s biggest enemy. To avoid the borer from evolving a natural immunity against the protein, crops are required to be a ratio of 80% of the GM plants to 20% of regular corn. Introduced in 1996, the modified corn has benefited farmers in Illinois, Iowa, Minnesota, Nebraska and Wisconsin, saving an estimated $7 billion in total.
