are laid on the small twigs in patches of a hundred and more. It 

 enters the ground when full grown and the moth appears the next 

 June. Where abundant on apple trees it may be destroyed by 

 spraying with Paris Green. 



The Apple-tree Case-Bearers. (Coleophora malivorella.) In the 

 •early spring there may often be seen on the twigs of the apple tree 

 little pistol shaped cases, each of them containing a small larva, 

 which has the power of moving from one place to the other with 

 this case They are principally feeding when young on the buds, 

 later they devour the leaves. They can be destroyed by hand 

 picking. 



The Apple-leaf Bucculatrix {Bacculatrix j)omifoUella.) The larva 

 of this small moth feeds on the oulside of the leaf. This larva 

 when disturbed lets itself down b3^ a thread of silk to the ground. 

 The insect is double brooded. The caterpillar attaches its cocoon to 

 the branches and here it hatches. The second brood hibernates in 

 the cocoon attached to the limb. 'Some seasons this insect appears 

 dn great numbers and then becomes verj- injurious to the foliage. 



Remfdy. The cocoons on the trees can be brushed with a solu- 

 tion of alkali ; this fluid will penetrate the cocoons and destroy the 

 inmates, or scrape the cocoons from the tree and burn them. 



The Codling Moth. {Carpocapsa pomonella.) This little moth, 

 as every fruit grower is well aware of, is the most difheult enem}' 

 to deal with. It is of foieign origin. It came to us from 

 Europe about the beginning of the present century. It is found 

 in almost all parts of North America and Canada, where it de- 

 stroys a great many apples yearly and so causing a considerable 

 loss to the apple grower. There are two broods of them. The 

 first moth appears as soon as the blossoms open. The female 

 lays a very small globular egg invariably in the eye of the apple just 

 forming. In about a week the young larva hatches and burrows into 

 the pulp to the core. It feeds then close to the core and in three weeks 

 is full grown, it now leaves the apple and hides under the bark ot 

 branch or trunk where it spins a cocoon of silk. The larva is yel- 

 lowish or pinkish, about one-half inch long with a horny brown head. 

 The pupa is about three-eighths of an inch long of light brown color 

 and hatches in ten days. This is the first brood of apple destroyers. 

 Now the females after having paired, lay another batch of eggs in 

 the later varieties of apples. Each moth lays about fifty eggs some- 

 times more. If left to their own way these intruders will soon spoil
