The diamondback moth is a formidable agricultural pest, causing tremendous losses on farms and requiring significant cultural and chemical-based management on both conventional and organic farms.  Dr. Tony Shelton has studied the diamonback moth for decades, and now has initiated the first open field trails of a genetically engineered sterile insect technique that could be a helpful solution.  Dr. Shelton discusses the potential risks, benefits, promises and pushbacks from proposing this technology.
