449 Repvort or THE HORTICULTURIST OF THE 
Keeping wood ashes about the base of the trees is considered 
by some extensive growers to be an effective treatment. The 
surest treatment is to kill the borers every spring and fall with 
a flexible wire inserted in their burrows or to remove them with 
a knife. 
After the borers are dug out in the spring in May, mound six 
inches high or more with fine earth, packing it tightly against 
the base of the tree. This compels the moths to lay their eggs 
on the bark above the top of the mound. About the first of 
August carefully examine the trunk by removing a little earth at 
the top of the mound where the borers, if any, may be easily 
found. Remove them with the knife. A second search should 
be made in October and a third one during the following May. 
If the earth is left at its usual level without mounding, the eggs 
are deposited so near the roots that the borers can easily work 
downward to where it will be difficult to find them. 
BUD MOTH. 
(T'metocera ocellana Schit.) 
Sometimes very destructive to the peach. The caterpillars 
bore into the buds and even into the wood beneath. Treatment 
same as recommended on page 409. 
CURCULIO. 
The plum curculio is sometimes a serious pest in the peach 
orchard. Remedies for this insect are discussed under “ Plum

eurculio”’ on page 455. 
FRUIT-BARK BEETLE. 
(Scolytus rugulosus Ratz.) 
Description.— The adult insects are black, somewhat cylin- 
drical beetles about one-tenth of an inch long and about one- 
third as broad. They appear early in the spring and bore small 
round holes through the bark to the sap wood. ‘The eggs are 
laid beneath the bark and the grubs feed on the sap wood, mak-
