The False Codling Moth (Thaumatotibia leucotreta or FCM) is a threat to many of our fruits, vegetables and other crops. Increased international trade and tourism has increased the risk of introduction of this pest. False Codling Moth can survive in climates described as tropical, dry or temperate. The first United States detection of False Codling Moth was in Ventura County, Calif., in 2008. It is estimated that approximately 20 percent of the continental United States may be suitable habitat for FCM.
