234 SUCCESSFUL FRUIT CULTURE 



the codlin moth, canker worm and apple maggot. The 

 cocoons may be also trapped by bands of cloth or straw 

 put around the trunks, and examined occasionally 

 during the summer, and the cocoons destroyed. 



. The Apple Maggot (Trypeta pomonella] (Figure 

 123) This is one of the most destructive of the insect 

 pests that attack the apple. The perfect insect is a 

 small fly, about one-half the size of the common house 

 fly, that appears in the latter part of the summer and 

 early fall, laying its eggs under the skin, through a 

 minute puncture which it makes. It attacks sweet and 

 mild flavored varieties more than very acid or winter 

 fruit, though some winter sorts are seriously injured by 

 the maggots. Most of the 

 injury is done as the fruit 

 is approaching maturity, or 

 after it has fallen to the 

 ground. 



Remedy No means 

 has been found by which- the 



Fig. 123-The Apple Maggot inS6ct Can be CaU S ht r 

 destroyed before the egg is 



laid, and therefore the only way it can be prevented 

 from doing harm is to gather the fruit before the eggs 

 are laid or to destroy the poor fruit while the larva is 

 still in the fruit. This is done practically and eco- 

 nomically by pasturing the orchards with swine and 

 poultry where the trees are low headed, and with cattle 

 and sheep if the head is high. If the fruit is picked 

 as soon as matured and put into closed buildings or 

 sold at once, few insects will be matured, but to have 

 this method a success all the growers in a locality must 

 do the same. Summer and fall apples must not be 

 allowed to decay on the ground, as it furnishes the 

 best possible place for their breeding. Fresh dropped 

 apples are worth from three to eight cents per bushel
