INSECTS AND INSECTICIDES. 
As the apple is forming the female deposits a single egg, 
usually in the eye or calyx of the forming fruit; from the 
egg a larva is produced, with black or brownish head, the 
body sprinkled with elevated dots, from each of which 
emanates a minute hair. In about one month the larva, 
having eaten its way through the core of the apple, reveal¬ 
ing its presence by a mass of reddish brown exuvise pro¬ 
truding from where it entered, leaves the fruit, reaches the 
ground by means of a silken thread which it spins, and 
seeking the trunk of the tree spins its cocoon. The early 
brood change to a chrysalis in three days, and in about two 
weeks the perfect moth escapes. This second brood is on 
the wing late in July, the female generally selecting the late 
apples in which to deposit its eggs. These larvae mature 
late in autumn, and spin their cocoons in come secure place, 
remaining in the larval state until early the following spring, 
when they change to a brown chrysalis, soon after which the 
moth appears to begin the work of the season. 
Remedies —The old method of bandaging the trunks 
has been abandoned, as it signally failed to accomplish 
its purpose, for various reasons. Recourse is now uni¬ 
versally had to spraying with Paris green or London pur¬ 
ple. This remedy is not only very efficient, but inex¬ 
pensive and easy of application. We applied London 
purple April 28th, and again twelve days later, in the 
proportion of one pound of the purple to 100 gallons of 
water, using the Field force pump and tank, mounted 
on the platform of a two-wheeled cart. Every alternate 
tree in a row of Duchess of Oldenburg was thus treated. 
This was too strong, as it hurt the foliage considerably. 
Probably half a pound of the purple to the same amount 
of water would be quite efficient, making two applica¬ 
tions ten or twelve days apart. A similar application of 
Paris green in the same proportion was made in another 
orchard April 28th and on May 10th. This proved to be 
satisfactory; the foliage was uninjured, and but few
