Vi white transparent, seldllue-
texture. The young larvae lies In
a crescent shape In the egg. When
it escapes from the egg 1t Stops to
feed on the foliage, and the poison
on the foliage often kills it; others
crawl direct to the apple and COM
mence to bore into the apple. The
larvae works fast and disappears In
the apple ia from two to ave min
utes. He finds that many larvae
enters the side of the apple where
two apples touch or a leaf touches
the apple. Many of them while
travelling over the apple to select
place to enter, select spot OF spray
material to start into the apple be-
because 1t being rough. gives a good
foothold. Many OF them die on the
surface of the apple and some of
them get through and beneath the
skin. BY close observation you will
find that in many wormy apples
the larvae have been eaten by small
black beetles.
The life of the larvae varies ac-
cording to temperature. One lasted
from June s to July 9, thirty-one
DAYS. and another from June 10 to
July s. sixteen days, and others be-
tween these dates. The second
brood began Matching at Medford
July 9 and continued through the
month up to the time the report was
made.
Spray Materials for A-rlving.
The asenate Of lead has been gem
orally used last season In preference
to Paris Green. though both have
given excellent results in arid Sec
tions, while the arsenate OF lead Is
preferred in the cost district, where
there is more humidity. Hood River
used about one pound of arsenate OF
lead to tree for the season. Swift's
directions are, for the first spray,
two and one-half to three pounds
to fifty gallons; for the second. two
to two and pne-half pounds. for the
third one and one-half to two
pounds, and the following sprays,
one to one and one-half pounds for
SO gallons Of water.
Use power outfit where possible
and maintain a pressure Of 40
pounds or more. The extension
rods should be as long as men can
successfully handle; also they
should be provided with a battery
of two or more nozzles. The dis
lance between the nozzles Is a mat
ter of considerable importance; II
too close together the cones Of spray
will interfere, but If they are wide
" separated on the T the inconven-
fence of handling Is greatly in
creased. II the nozzles are not set
50 as to point away from each other
at slight angle the cones Of spray
will ont come together nearly so
quickly as when they are set paral-
lei. This result is also obtained by
using a nozzle which throws mar
row cone OF spray, such as the long
distance Bean. When hand pump
is used it is not practicable to use
SO many nozzles or maintain such
may be done with such an outfit
If SUFFICIENT time is taken to insure
thorough wetting Of the tree.
Spraying tree: Do the inside
spraying first. and then, beginning
at the top. apply the overshot or
outside spray. Do not finish the
sides and bottom until the top ia
thoroughly sprayed. The men
should walk completely around the
tree and spray directly at 1t from
all sides. Do not try to spray
around corner. Before leaving any
part of tree the men should stand
we'll back and spray the tips OF the
extending branches.
The orchardist should insist on
the tops of the trees being sprayed
first and thoroughly. II this upper
work is done we'll the lower branch
es will receive almost enough spray
from the drip, and they can then be
finished quickly. thus avoiding the
greater drip loss which comes about
through beginning at the bottom
Do not vast spray on the trunk and
large limbs which are bare OF fol.
iage.
In Utah as the result of thu
two sprayings, seventeen-eigh
teenths of the worms were killed
therefore, the second brood was
very much diminished.
Second Brood.
The proper time to spray for tn
second brood would naturally be II
about so days from the entrance O
the first worms: but 1t Is not bes
to figure by days, as the tempera
ture varies the cycle periods. Thu
better way is to determine by brood
ing cages or counting the worm
under the bands. II you use ;
brooding cage take a fruit Jar, pu'
in some cocOpns, cover the top will
