destroys them. When the new shoots start, the borer eats into 
them causing them to wilt and die. Many of the second brood of 
this borer eat into the peaches, causing a gummy exudation and 
ruining them for market. The larvae that appear in the spring 
spent their winter in little excavations which they made in the 
fall in the bark of the trees. See Figs, n and 12. 
Remedies . —Early in the spring, just before the buds open, spray the 
trees with lime and sulfur wash (21). Whale-oil soap (12) in the propor¬ 
tion of a pound to two gallons of water. Fish-oil soap (13) diluted once with 
water, or kerosene emulsion, will doubtless do the work nearly or quite 
as well as the lime, sulfur and salt. Many of the larvae may be caught 
under bandages (33) used as for the codling moth. 
Mr. E. P. Taylor has had excellent success with arsenate of 
lead (5) at Palisade, Colo., this season.

THE PEACH BORER. 
A yellowish white borer attaining the length of about one 
inch, boring beneath the bark of the lower trunk, crown and 
larger roots. See Plate 4. 
Remedies .—Carefully inspect the trees every fall and spring, remove 
some of the earth next the crown, and search for and remove the borers 
with the aid of a pocket knife. Their presence is usually indicated by 
the exhudation of a gummy material upon the bark. Shields of stout 
paper or wire screen placed about the trunks and left therefrom the 1st of 
June till the 1st of August will serve as a means of protection from egg- 
laying. The paper screen is the better. (See Plate 4, Figs. 2 and 3.)
