THE CODLING MOTH AND ITS TREATMENT. 

 BY A. L. MELANDER. 



The Codling Moth is a brownish miller about one-half inch 

 in length, which lays eggs on or near apples. In a little 

 over a week the eggs hatch into Codling Worms. In nearly 

 all localities two distinct broods of worms occur each year. 

 After feeding within the apple for several weeks the worms 

 leave the fruit to cocoon. Most worms make their cocoons in 

 the ground, many can be found ben.eath rough bark. The

cocoon stage is completed in from two weeks to a month dur- 

 ing the summer. Worms leaving apples late in the summer 

 remain in the cocoons over winter. When the cocoon stage is 

 completed the Codling Worm has changed to the Codling 

 Moth, and is ready to lay its eggs. 



HOW TO COMBAT THE CODLING MOTH. 



The only remedy for the Codling Moth is spraying. Other 

 measures are useful but can not be depended on alone. Clean 

 culture, especially stirring up the ground beneath the trees, is 

 of great importance as it destroys the worms in their cocoons. 

 Banding trees with burlap will' trap 40 per cent, of the worms.
