appease their hunger after the long journey, and then boring 

 directly for the core. This feeding in the blossom end is of the 

 utmost importance in enabling us to destroy the young worm by 

 spraying, as will be indicated later. The rest of the worms enter 

 the fruit through the side, often where a leaf or another apple 

 comes in contact. The seeds of the apple seem to be most relished 

 by the apple worm, for it soon hollows out each of them as well 

 as the sui-rounding core, its work being indicated by the well- 

 known excreta thrown out of the calyx, showing the "wormi- 

 ness" of the apple. In from twenty-five to thirty days, having 

 attained full growth, it eats its way out through the side of the 

 apple, through which a round exit hole is left, and seeks a place

in which to form a cocoon. The full-grown apple worm is about 

 three-fourths of an inch long, of a whitish or often pinkish color, 

 and so well known as hardly to require further description. 



About the last week in July the full grown larvjp commence 

 to leave the apples and form their cocoons, and from that time 

 until the apples are picked they continue to emerge, the larger 

 number being formed about the first of September. The cocoons 

 are formed under the bark, as already described, and there most

The Second Brood. A few of those larvag which become 

 grown by the last of July or the first week in August transform 

 to pupa; the same as in the spring, and give rise to a partial 

 second brood of moths. Only a part of the first matured larvse
