(7) The continuance of the 1937 high levels of horer population in 
Hartford and Hew Haven Counties, Conn.

In 1938 early market sweet corn was severely damaged by the corn borer 
west of Toledo, in Lucas County, Ohio; near Sandusky, in Erie and Huron Counties, 
Ohio; and in the vicinity of How Haven, in He^ Hayen County, Conn. Lighter in- 
festations were observed in localities surveyed in Wayne County, Mich., Cuyahoga

in 1938 and in the years 193^ to 1937* inclusive, are given in table 3« Corn
