PLUM BORER FEEDS ON INJURED TREES 
The American plum borer, an insect which attacks im¬ 
partially plum, cherry, peach, and apple trees, has been 
found by investigators of the U. S. Department of Agri¬ 
culture, to confine itself entirely to those trees which 
have received some previous injury. It is, it is said, en¬ 
tirely unable to establish itself upon vigorous, healthy, 
uninjured trees and for this reason, except in occasional 
cases, is unlikely to become a pest of more than ordinary 
importance. It is frequently found, however, on apple 
trees which have suffered from collar blight. 
In order to prevent infestation by the American plum 
borer a professional paper of the U. S. Department of 
Agriculture, Bulletin No. 261. recommends the precau¬ 
tion of cutting away the dead bark and painting the 
wounded area on all injured trees with any non-injuri- 
ous tree paint. After the borer has once established it¬ 
self the cutting-out method is the only one that can be fol¬ 
lowed. When the proper conditions are present the plum 
borer can do considerable damage, and it is therefore ad¬ 
visable to take precautions against it.
