Diamondback moths with a lethal gene could help control crop pest
Cabbage-chomping moths genetically modified to be real lady-killers may soon take flight in upstate New York. On July 6, the U.S. Department of Agriculture OK’d a small open-air trial of GM diamondback moths (Plutella xylostella), which the agency says do not pose a threat to human or environmental health.

Originally from Europe, diamondback moths have quite the rap sheet:
