etc. There is a common notion among some farmers that the larva of 
this insect is that of the codling* moth, and the writer has often ])cen 
told that the codling moth was introduced ))y its larvte being imported 
in dried fruit. We 
have no reliable rec- 
ords of the codling

T/ie apple fruit-ininer {Argyi'esthJa conjugeUa) 
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 larvje are about 
one-fourth of an inch in length, are of a 
dirty Avhite 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 country. 
Apple find f -hover (La rem a h ereJlerd) . — 
This insect is said to have gained a foot- 
hold in British Columl)ia. The larva^ 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 cocoon in the earth. They 
hibernate as pupae, and there is onlv one 
generation each year. The species is 
shown in fig. 3, which also illustrates its 
manner of work. 
Pear frult-hrrer {Xephoj>tery;r ruhizonella.) — It is stated that in 
Japan the pear crop is injured to the extent of 30 to .50 per cent each 
3^ear by this insect. The eggs are laid in clusters on the twigs and
