The Peach Borer. 7 
THE MOTH. 
The moths of the peach borer are beautiful clear-winged insects, 
the male differing strikingly from the female in markings. In the 
male (fig. 8) the wings are transparent, with steel-blue trimmings 
along the margin and veins, . 
and the abdomen is marked 
with narrow yellow bands, 
quite conspicuous on the 
steel-blue ground color. 
The female (fig. 9) is steel- 
blue, with opaque forewings, 
and there are one or two 
orange-colored bands around 
the abdomen.

these. Very soon after emergence mating takes place and oviposition 
begins. It is doubtful whether the moths feed to any extent during 
the course of their lives, and within a few days the eggs have been 
deposited and the moths have died.

HOW TO CONTROL THE PEST. 
Many methods of control of the peach borer have been proposed 
during the more than 150 years that this pest has been known to in- 
jure the peach. Horticultural literature contains numerous accounts 
of the experience of growers with this or that wash or method of treat- 
ment of the borer, and entomologists, during the last 20 or 30 years, 
have given much time to discover, if possible, ways and means of 
preventing or reducing its injuries. While some of the washes and
