out of the ground, and anything to prevent that moth from 

 crawling up the trees is sufficient. The best thing for this 

 pest is whatever keeps sticky the longest and that is Tree 

 Tanglefoot. 



For the fall canker-worm the band should be put on 

 about the first of October. If it is the spring canker-worm 

 the band should be put on about the first of March. The real 

 trouble is that most people do not know that the canker- 

 worms are present until the worm is feeding on the leaves. 

 In this case, spraying with arsenate of lead will be effective. 



The Pear Psylla 



Winters in the adult condition and in the spring lays its 

 eggs. The young suck the juices from the tree and when 

 abundant often check its growth entirely. The tree should 

 be sprayed with kerosene emulsion from the 15th to the 

 20th of May. 



Peach Borer. 



The adult of this pest is a very pretty little moth. These 

 moths appear from about the 10th of July until the 1st of 

 September and fly freely in the daytime, reminding one of 

 small butterflies. The eggs are laid singly on the trunk, and 

 the borer which hatches works its way through the trunk 

 into the stem and feeds until winter comes, then becomes 

 quiet. In the spring, it starts again and when through feed- 

 ing, makes its way outside, transforms to the adult, and es- 

 capes. 



The Plmn Curculio 



As an apple pest is becoming very much more important than 

 we appreciate, for it not only attacks and injures 80 to 90 

 per cent, of the plums, but going to the apples feeds upon 

 them, and while I doubt if the plum curculio ever matures 

 in the apple, it has an effect on the apple itself, so if you find 

 an apple indented at one point and a hardness running into 

 the core, you may decide that the plum curculio has been at 

 work there. We must count the plum curculio as one of the 

 worst apple pests in Massachusetts today. 



The Tussock Moth 



Is a general feeder, including fruit trees. This insect is not 

 often very abundant, and can easily be controlled by spray-
