Forecasts are limited to the country’s main crop production regions east of the Rocky Mountains and west of the Appalachian Mountains and parts of Canada. Insect forecasts are based on data analyzed from moth traps located throughout the United States’ main crop production regions as well as predicted weather patterns and field reports and research. Forecasts are estimates based on available information and cannot guarantee actual insect pressure risks. Recommendations for insect pressure risk forecasts are based upon generally accepted practices. Forecasts and recommendations should not be used as a substitute for sound farming practices, including diligent field monitoring, or as a sole means for making risk management decisions.
