Pyrausta nubilalis Hubn. 
The European corn borer easily ranks as the most important pest 
which has become established in the United States during the last 
25 years, since the probabilities favor serious and widespread losses 
to our principal grain crop. The yield of corn is approximately 
twice that of oats and three times that of wheat. This new pest not 
only attacks corn, both sweet and field, but it may prove a serious 
enemy of Kafir corn and possibly greatly injure Johnson and Bermuda 
grass. The annual loss in this country might exceed a billion dollars, 
which would mean considerably less than 50 per cent damage to our 
1918 corn crop of 2,582,814,000 bushels, which sold at a little over
