 to lay their eggs upon the young corn plants of a new 

 season. 



This Cornstalk-borer is especially destructive in regions 

 where old cornstalks are left in the field through the winter. 

 The destruction of these, with the hibernating caterpillars 

 inside, will very largely reduce the injury the following 

 season. It is another one of the numerous insects which 

 point the moral that " good agriculture is the first and best 

 insecticide."

It is more than a century since the Codling Moth or
