INSECTS AND BIRDS 



as the San Jose scale may do. When full grown, the 

 worm leaves the apple and hunts out a secluded spot, per- 

 haps under a bit of bark. There it spins around itself a 

 loose silken cocoon. A small gray moth hatches from 

 this cocoon. Spring cocoons hatch in the summer, and 



fall cocoons hatch the 

 following spring about 

 the time of apple blossom- 

 ing. 



The moth can best be 

 destroyed while in its 

 worm stage. 1 Since it is 

 a chewing insect, its de- 

 struction is affected by 

 spraying with lead arse- 

 nate or with Paris green. 

 The spray should be ap- 

 plied on the young fruit 

 as soon as the petals have 

 fallen, and before the 

 calyx has closed about 

 the pistil. Spray thor- 

 oughly into and all

The mother lays an egg 

 on or near the flower. 

 In a few days a tiny 

 worm hatches from the 

 egg and by instinct it is guided toward the enlarging 

 ovary. If this has been covered with poison, the worm's 

 first meal is its last. The tree should have a second spray-

1 Insects in their development pass through several stages. In the case of 

 moths the stages are four in number; namely, egg, worm, pupa, and adult. 

 It is the pupa that is inclosed in a cocoon, or silken bag.
