THE APPLE. 



in this section some years, closely resembles the foregoing in ap- 

 pearance, but it builds only a very thin web against the trunk or 

 branches of the trees, and they march in every direction. At night 

 they collect in groups on the trunks and branches of the trees, 

 where they may be easily destroyed. The egg masses resemble 

 those of the tent caterpillar, but as these are generally high up on 

 forest trees it is impracticable to gather and destroy them. The 

 best remedy is to poison the infested trees with Paris green, as 

 recommended for the tent caterpillar. 



CLIMBING CUT- WORM (Agrotis ,sp). When the foliage or buds 

 are being destroyed without any apparent cause, climbing cut- 

 worms should be searched for. They will be found buried in the 

 ground near the base of the trees. They are closely allied to and 

 resemble the common cut-worms, so well known to gardeners, and 

 occasionally do much damage. They may be destroyed by spray- 

 ing the foliage as recommended for the tent caterpillar and by 

 jarring the trees after dark, having first spread sheets on the 

 ground. Putting a cone-shaped piece of zinc or tin around the 

 tree, so that they cannot gain a foothold on it, will keep them off 

 the trees. 



CODLING MOTH (Carpocapsa pomonella). Figure 65 plainly 

 shows the work of this pest. It is the common cause of wormy 



apples, and causes the 

 infested fruit to ripen 

 prematurely and fall to 

 the ground. The moths 

 deposit their eggs in 

 the calyx or eye of the 

 apple just as the blos- 

 soms fall. On hatching 

 the worm eats into the 

 fruit, where it lives un- 

 til it is ready to change 

 to the moth stage, when 

 it leaves the fruit and 

 spins a cocoon in which 

 it undergoes its change. 

 There are several 

 broods in a season. The 

 worms that are in the 

 late apple leave them 

 in the winter and find

REMEDIES. The fallen fruit should be promptly gathered and 

 destroyed. Keeping hogs in an orchard is very beneficial. If
