 They hatch in 5 or 6 

 days. 



The injury caused 

 by this insect has 

 often been confused 

 with the work of the 



codlin-moth. Many Fig. 22. — Work of lesser apple worm at the

01 the young larvae 



enter the fruit through the calyx cavity, while others bore 

 through the skin just outside the calyx, and still others enter 

 at the side and near the stem. A larger proportion of the first 

 brood enter at the calyx than is the case with the second genera- 

 tion. In general, the burrows are not so deep as those of the 

 codlin-moth. The larva remains near the surface and eats 

 out a blotched mine just beneath the skin which turns whitish 

 and greatly disfigures the fruit (Fig. 22). 



In the North there are two generations annually ; in the Ozark 

 region there are three and sometimes a partial fourth brood.
