The flight of the western bean cutworm is coming to an early close this year. Blacklight trap captures from both Boone and Woodbury counties indicate that the populations peaked on July 5 and July 9, respectively (see figures). The historical data from Woodbury County indicates that the flight started six days earlier, and peaked six days earlier, than it had any previous year in western Iowa. It appears that the flight will end considerably earlier; maybe by as much as 10 to 14 days.
