Caption for September 2014 Agricultural Research magazine article, "Weather-Tracking Tool Helps Track Migrating Insects." Corn earworm larvae can cause great damage to cotton and corn crops. Using the NEXRAD weather monitoring system, ARS scientists have found a way to more accurately track corn earworm moths as they migrate at night. This knowledge can help farmers determine when to treat for the pest.
