THE CODLING MOTH 
THE CODLING MOTH, . 
Carpocapsa Pomonella, L. 
The Codling Moth is not a native of America 
but was imported from Europe about one hundred 
years ago. As a large number of the worms of the 
fall brood do not leave the apples until the latter 
are stored in cellars or in barrels, this insect is un¬ 
avoidably introduced wherever apples are shipped. 
Consequently it has spread rapidly, not only in this 
country, but to nearly all parts of the globe where 
apples are grown from cold Siberia to sub-tropical 
regions. 
LITERATURE. 
The amount of literature that has accumulated 
on the Codling Moth in this country is very great 
and, in a considerable part, especially that occuring 
in local news papers, is of little value. It would be 
useless to endeavor to give anything like a full 
bibliography of this insect in the present paper, but, 
for the benefit of those who wish to go deeper into 
the subject, I will recommend the following articles 
as being especially valuable and easy of access:
