spray with arsenate of lead paste, mixed in water, at the rate of 

 two pounds to fifty gallons, as soon as the petals have fallen from 

 the trees, the same as for the codling moth. A second and third 

 spray should be applied at intervals of ten days or two weeks. 



Summer cultivation also lessens the number of these pests by 

 destroying them in their earthen cells. All wormy and fallen fruits 

 should be destroyed promptly. 



Since the codling moth and curculio are found upon the same 

 trees at much the same time, the treatment for codling moth sup- 

 plemented with one additional sj^ray ten days or two weeks after the 

 second, is found etlective in also controlling the curculios.

THE TENT CATERPILLAR 



The American Tent caterpillar, also called the Apple-tree Tent- 

 caterpillar, is usually found infesting apple and wild cherry trees, 

 although when these trees have been stripped of their foliage they 

 will feed upon the leaves of peach, plum, nmple, elm, poplar, willow, 

 and other fruit and shade trees and bushes. 



The eggs are deposited in June or July by stout, hairy, brown- 

 ish or buff-colored moths on the twigs in bands or cylindrical masses, 

 and covered with a glutinous secretion, which soon hardens 

 and protects them. About the time the buds open in the spring 

 the young caterj)illars eat their way out of the egg cases, and begin 

 to feed upon the foliage. In ;>. few days they liegin to build their 

 wliite "tents" in the forks or crotches of the limbs, to which they 

 retire for rest and protection from the weather. They leave a trail 

 of silk behind them Avhile traveling about in search of food, and 

 twigs near the tent become covered with a dense mat of web. 



The larvae feed greedily for six or seven weeks, attaining a length 

 of about two inches. Pupation occurs in the tent, or on the trunk 

 and large limbs of the tree, or in rubbish around the tree. 



Treatment: Cut off and destroy the egg massc^s before the foliage 

 a])pears. Remove and burn the "tents" while still small. Cut down 

 all large wild cherry trees near tlie orchard, and treat small ones. 

 Sj»ray trees about the time the caterjullars begin to feed with 2 

 ])ounds of arsenate of lead mixed in 50 gallons of water. Do not 

 burn the tents while in the trees, as the branches are injured by 

 tho he.it. Some ]:ersons shoot them away with shot guns loaded 

 with powder and j)a])er only. Others remove them with bristle 

 brushes on the ends of poles. 



BUD MOTH 



Tin's very small, dark, ashen-gray moth lays its eggs during mid- 

 summer, and from tliose hatch small i)]'ownisli caterpillars, which 

 pass the winter encased in tubes made from the rolled up half of a 

 leaf. From this they emerge, about half grown, in early spring 

 when the buds are be-ginning to swell, and eat their way into the
