I. Lesser Apple Worm. 

 {Bnarmonia prunivora.) 



The larva feeds upon the apple in a manner similar to that 

 of the codling moth, for which it is doubtless frequently mis- 

 taken. Besides by its smaller size the larva may be distin- 

 guished from that of the codling moth by the presence of the 

 anal fork. The adult moth expands about ^ of an inch across 

 the wing. The ground color of the front wings is black, with 

 patches of pale rusty red, of gray, and of yellowish white and 

 steel blue oblique lines. The hind wings are dusky gray at the 

 base, shading to black at the apex. 



REMEDIES. 



The insect may be combated by spraying used against the 

 codling moth. 



2. The Codling Moth. 

 (Carpocapsa pomonella L.) 



The codling moth passes the winter in the larval stage in 

 silken cocoons in cracks and holes in the trees and in houses 

 where apples have been stored. In the spring these larvse 

 change to pupae, and the moths emerge about a month after the 

 apple is in blossom. 



The moth (fig. 40, a) varies somewhat in size, but the maxi- 

 mum spread of its wings is about three-fourths of an inch. 

 The front wings are of a brownish gray color and are crossed 

 with lines of gray scales, giving them the appearance of watered 

 silk. At the tips of the wings there is a large brown spot, in 

 which are many scales of bronze or gold. The hind wings are 

 grayish brown in color. The moth lays her eggs, a few days 

 after emergence, on the leaves of apple or other food plant, or 

 on the fruit. A majority of the eggs of the first generation 

 are laid on the leaves, while the greater part of those of the 

 second generation are laid upon the fruit. 



A large number of the larvae which hatch from eggs deposited 

 on the leaves eat small portions of the leaves before finding 

 fruit. The larva, living most of its life within the fruit, throws 

 out through its entrance hole, which it enlarges from time to
