Seed growers at Grand Forks, B. C., on the suggestion of Henry Wiebe, Manager, Grand Forks Co-operative Growers' Exchange, used DDT as an emergency measure to control cutworms during the month of May, 1946, after supplies of bait ingredients had been exhausted in that district. The species involved were determined by K. M. King as Euxoa ochrogaster (Gn). with a few E. tessellata (Harr.) , and other related species.
