248 THE BOOK OF CORN 



generation of the corn worm, while later, the second 

 generation is found in the ends of the ears doing seri- 

 ous harm late in the summer and early fall. 



7 — Sometimes a series of shot holes are found 

 extending across a well-developed leaf. The holes are 

 usually elongated and arranged side by side quite 

 regularly, and are usually the work of one of the corn 

 bill bugs. 



8 — Sometimes the leaves of young corn are irreg- 

 ularly eaten away, many of them having a gnawed 

 appearance at a time when the stalk is less than a foot 

 high. In such instances usually fine particles and 

 small lumps of earth at the base of the plant will be 

 found closely webbed together in a mass usually about 

 the size of an ordinary walnut. Such condition is the 

 result of the work of the root' web worm. 



9 — The work of the ordinary cutworm is well 

 known to most farmers. The young corn is usually 

 cut above and below the surface of the ground and 

 examination usually reveals the culprit hidden in the 

 ground not far away. 



10 — If the stalk has a small hole with brown, 

 moist powder exuding from it, it is sufficient evidence 

 that the cornstalk borer is at work within. These 

 creatures do great damage to young com in the spring, 

 especially on low ground. 



II — ^When an ear is found with the end eaten and 

 burrows leading into it from the tip toward the base, 

 the destructive corn worm can usually be found. Its 

 burrows are usually filled with excrement, discoloring 

 and injuring the ears to a considerable extent, while 

 they are in the soft stage. 



12 — ^Injury by grasshoppers is not uncommon, 

 and often the entire leaf is eaten, leaving only the 

 midrib, while others are gnawed and filled with irreg- 

 ular holes, giving them a very ragged appearance.
