etc. Thoro is a common notion among- some farmers that the larva of 

 this insect is that of the codling moth, and the writer has often 1)cen 

 told that the codling- moth wa.s introduced by its larvte being imported 



in dried fruit. We 

 have no reliable rec- 

 ords of the codling 

 moth having ever 

 eaten dried fruit, 

 and the Indian-meal 

 moth is the princi- 

 pal insect that has 

 been reared from 

 such sources. The 

 caterpillar is nmch 

 smaller than that of 

 the codling moth, 

 and can be easih^ distinguished from it (tig. 2). 



The apple frult-iniiui' {Ai'ejiji'e^thJa conjr((/elJa). — The larva of this 

 insect has been found attacking apples' in British Columbia, and injuries 

 which may have been caused by it have been noted in Washington, 

 Idaho, and Montana. The larvae are about 

 one-fourth of an inch in length, are of a 

 dirty white color, tinged with reddish when 

 full grown, and taper at each end. The 

 tunnels made in the fruit are numerous, 

 and extend in all directions. 



There are two species of Lepidoptera 

 which do great damage to apples in Japan, 

 which may sooner or later succeed in en- 

 tering this countrv. 



Ap>pJ<' fr>i!f-horei' {L<(rerna herellera). — 

 This insect is said to have gained a foot- 

 hold in British Columl)ia. The larv» live 

 only at the core of the fruit, injuring the 

 seeds. When full grown they make a pas- 

 sage out, crawl or drop to the ground, and 

 spin a white coccon in the earth. They 

 hibernate as pupa\ and there is onlv one 

 generation each year. The species is 

 shown in tig. 3, which also illustrates its 

 manner of work. 



Pear friuf-lxtrcr [Xej'Jtopfertj.r ri(hizonella.) — It is stated that in 

 Japan the pear crop is injured to the extent of 30 to 50 per cent each 

 year by this insect; The eggs are laid in clusters on the twigs and
