TREES Gypsy MOTH
WILL NOT HURT
Many Species in the Infested
Areas Which Are Not Susccp-
tible to the Pests Attacks

Washington. July ga large num-
Der Of trees have been found not to
be suspectible to attack by the gypsy
moth and recent Investigations by the
Department of Agriculture have
shown that the larvae Of the moth
will not feed upon their foliage. In
the heavily infested sections Of New
England. therefore, prospective tree
planters are urged to select species OF
this character wherever their require
ments can be met with such trees.
In Bulletin No. $50, a professional
paper of the United States Depart
ment Of Agriculture, the trees and
plants Of New England are divided
into four classes according to the de-
gree of their susceptibility to the
gypsy moth. In class l are included
those which are most favored by the
pest. Glass contains the species
that are favored by the larvae after
the earlier larval stages are passed.
Glass consists of trees and shrubs
upon which a small proportion of the
gypsy moth larvae may develop. In
class are the trees and shrubs upon

practical purposes no difficulty is
likely to be experienced as long as the
species in class 1 are not present.
Unfortunately, however, this class
contains the oaks and birches which
predominant in much Of the infested
aera. Glass l and class between
them also contain most of the species
Of high commercial value. In spite
Of this difficulty. however, by consult
ing the lists given below. both private
and municipal planting may be so
done that injury from the moth is
minimized.
In orchards, the tree most likely to
be affected by the moth is the apple.
Spraying with arsenate Of lead at the
rate of 10 pounds to 100 gallons OF
water will control moderate infesta-
tions of the gypsy moth, as we'll as Of
the codling moth. Additional pre-
cautions that are desirable are to fill
or cut down all hollow trees and
clean up or burn all rubbish in which
the moths may deposit their eggs.
In severe infestations, the creosoting
trees with sticky fiy-catching prep
dTdtlOnS may DE necessary.
