APPLE GROWING 



rubbish beneath the tree and spins a tough but 

 slight silken cocoon in which the pupal period is 

 passed. This lasts about a fortnight, when the 

 process is sometimes repeated, so that In the 

 Eastern States there are often two broods each 

 season. 



The most vulnerable point in the career of 

 this little animal is when It is entering the fruit. 

 If a fine poison spray covers the surface of the 

 fruit, and especially if It covers the calyx end 

 of the apple inside and out, when the young 

 larvae begin to eat they will surely be killed. It 

 Is estimated that birds destroy eighty-five per 

 cent, of the cocoons on the bark of trees. 



2. Apple Maggot. — It is fortunate that the 

 apple maggot, often called the railroad worm 

 because of its winding tunnels all through the

 for it Is much more difficult to control with a 

 poison. A two-winged fly appears in early sum-

 and the maggots begin to burrow indiscrimin-

 are a greenish white in color and about a quar- 

 ter of an Inch long. From the fruit this Insect 

 goes to the ground where the pupal stage Is
