to leaves which fall to the ground ; therefore, if all the dead and dried 

 leaves be gathered in the fall and burned, also all the decayed fruit, 

 a great many of these insects would be destroyed. As the cater- 

 pillars feed inside of the berry, no spraying of the vines with poisons 

 would reach them. The caterpillar makes a discolored spot where it 

 enters the berry. Fig. 23, c, therefore the infested fruit may be easily 

 detected, and destroyed. 



There is a small parasite that attacks this insect and helps to keep 

 it in check. The insect has been known in Europe over a hundred 

 years. It is not certain when it was introduced into America, but 

 it is now found from Canada to the Gulf of Mexico, and from the 

 Atlantic to the Pacific ocean. 



THE CODLING MOTH. 



Carpocapsa pomonella (Linn.) 

 This well known insect has a world wide reputation, and is now 

 found wherever apples are raised. 



Fig. 24. 

 The moths are on the wing about the time the young apples are 

 beginning to set, and the female lays a single egg in the blossom end 

 of each apple. The Core wings of the moths when expanded, Fig. 

 24, g, if, with the wings closed,) measure about half an inch across, 

 and are marked with alternate wavy, transverse streaks of ashy gray 

 and brown, and have on the inner hind angle a large, tawny-brown, 

 horseshoe shaped spot streaked with light bronze or copper color. 

 The hind wings and abdomen are light brown with a lustre of satin.
