A CORN STALK BORER ( Hadena sp.) 
Ohio T» H. Parks (June 22): The Hadena stalk borer has been 
seriously damaging young corn in fields planted on timothy 
sod (spring plowed) in several eastern Ohio counties. The 
borers tunnel down the stalk and destroy it. Some fields 
have had to be replanted. One farmer in Carroll County 
plov/ed part of his timothy sod in the fall, a second part 
in late winter, ard the remainder in late spring. The only 
damage that occurred was on the part plowed in. the late 
spring. Pall and winter plowing seemed to control. Damage 
has been reported from Carroll, Tuscarawas, Jefferson, 
Harrison, and Portage Counties. These are all in eastern Ohio,
