A sample of potatoes showing tuber worm injury was submitted to the Entomology Department by a farmer of Elmwood (Cass County), Nebraska in September 1939. A few days later the farm was visited and a bin of about 125 bushels of potatoes was found to be heavily infested with the potato tuber worm. In compliance with instructions, the grower either used or destroyed the entire crop during the early part of the ensuing winter. Potato fields in the same vicinity were examined the following year, but no specimens or evidence of injury by this pest could be found. Apparently, this is the first record of the potato tuber worm, Gnorimoschema operculella (Zell.), in Nebraska.
