THE CODLING MOTH. 
FOOD PLANTS. 
The Colcling Moth, though partial to the apple, 
also attacks the pear, quince and wild haw and h&s, 
in rare cases, been reported as feeding in pit fruits 
as peaches, plums and apricots. 
NATURAL ENEMIES. 
Nature’s checks upon this insect are numerous 
but very ineffectual. The more important natural 
enemies are insectiverous birds, and two species of 
insect parasites belonging to the family Hymenop- 
tera to which family belong all our ants, bees and 
wasps. 
ARTIFICIAL REMEDIES. 
Under this head I will mention first the use of 
the arsenites, London purple and Paris green, as 
they are by far the most important. 
Who first used arsenic in any of its forms for 
the destruction of Codling Moth larvae it is impossi¬ 
ble to say. Among those who were early in bring¬ 
ing London purple and Paris green into popular 
use for the destruction of this pest are Prof. A. J. 
Cook of the Michigan Agricultural College, Dr. S. 
A. P'orbes of the Illinois State Laboratory of Natu¬ 
ral History, and Prof. E. S. Goff formerly of the 
State Experiment Station, at Geneva, N. Y. 
Within the past few years a great many en¬ 
tomologists and practical fruit growers have used 
these arsenites for the destruction of the apple 
worm and, so far as I can learn, there has been but 
one verdict where a fair trial has been made and 
that is in favor of the application.
