CROP PRODUCTION 



The eggs of the Spring Canker-worm are laid in spring. 

 The larvae of both species hatch as the buds are opening 

 and attack the young leaves, often doing great damage. 

 They are looping caterpillars or measuring worms. 

 When fully grown they, change to pupae at or near the 

 soil surface. The female moths are wingless. Spray- 

 ing with arsenate of lead before the blossoms open and 

 after the petals fall will destroy these pests. 



In some parts of 

 New England the 

 Brown-tail Moth and 

 the Gipsy Moth are 

 exceedingly destruc- 

 tive to apple orchards. 

 In New York and 

 other regions the 

 Bud-moth Caterpil- 

 lars and Case-bearers 

 are injurious. In 

 most eastern and mid- 

 dle western states the 

 Apple Tent-caterpil- 

 lar is often destructive. These pests may all be 

 controlled by spraying with arsenate of lead. 



Enemies of the Fruit 



The Codling Moth or Apple Worm is one of the most 

 generally injurious insects affecting apple fruits. The 

 eggs are laid by a small moth, usually upon the green 

 fruit or the leaves. They hatch into whitish worms that 

 burrow into the young apple and feed upon the pulp
