HOW TO CONTROL THE
COOLING MOTH

OaAAdP DabAo PidNCu al OdHu lHt
trunks of apple and pear trees, the
disposal of infested fruit in the or
chards, the packing and storing oil
the fruit in tightly screened rooms
and the storing of bags, barrels and
boxes which have contained fruit in
screened rooms are four important
measures which effectively supple
ment spraying for the control OF
the codling moth. 1t is frequently
impracticable for the owners of a
few dooryard trees to spray prop
erly, and the measures mentioned
will enable one TO protect the fruit
to greater or less degree, depend
ing upon the neighborhood condit-
ions. Being comparatively inexpen-
sive. commercial orchardists who
have made one thorough and proper
ly timed application of poison, can
use these measures to greater ad-
vantage than a second, third, or
even a fourth spraying of the
trees.
Trapping the Worms With Bands.
The codling worms remain inside
the fruit until full grown, when they
are ready to spin their cocoons and
transform into the winged adult
stage. When full grown, if the
fruit has not already dropped, the
worm energies and crawls down the
branches in search of a hole or
crack in the tree, crevice under
loose bark, or other protected loca-
ton. The object of banding is to
provide an attractive place in which
the worms will spin their cocoons.
The first step consists in scraping
off the loose bark from the larger
branches and tree trunk, and clean
ing out cracks and holes and filling
them with cement For each tree
(apple and pearl a band of burlap
about a foot wide and long enough
to go around the trunk of the tree
twice is needed. The strip of burlap
should be folded once lengthwise
and wrapped around the trunk of
the tree just below the lowest
crotch with the loose edges below.
The. top should be drawn tight. The
ends may be held in place by a
small-headed nail driven into the
tree. If properly arranged, the
band can be removed for examina-
ton and replaced without removing
the nail. Bands should be removed
and examined every nine or ten
days to insure that no moths de-
velop and escape. In Southern Ari-
IONA they should ordinarily be in
place unon the trees by the middle
Of May, except in Tate" seasons
when the first of june is sufficient
Iy early. Cooling larvae (worms)
and pupae found at each examina-
ion should be killed by crushing or
cutting in two with a knife. It'll
81 ould always be borne in mind that
i not regularly examined the bands |
are a positive aid to the insects.
The bands should be left on the |
trees until all of the fruit is picked, |
put they need not be removed for
examination and destruction |
Of the worms later than September
18th. When the bands are removed |
many cocoons will remain attach /
ID to the bark and some worms
will drop to the ground. Attention
must be given to these as well as
o the worms and pupae which are
emoved with the bands.
Disposal of Infested Fruit.
A small, but by no means negli-
yible, proportion of the worms are
:arried to the ground in so-called
'windfalls.' particularly during the
middle OF the season In one in
tance (Aug. IA. 19lD, ten apples
,ut of a total of fifty windfalls

Pest Inspector, R. F. L. Wixom,
If Thatcher. were found to contain
i've codling worms. To prevent the
development of such worms all
should be picked up and
ed to hogs or buried in the ground
It least once week At the same
inc, il the ground under the trees
S kept free from trash and dust
to prevent cracking, more
II the worms which escape from
he windfalls will crawl up the tree
runks and spin their cocoons under
he burlap bands where they may
,e disposed of together with those
worms which crawl down the bran
hes to the bands. A great deal of
ruit is undesirably small on ac-
cunt OF the growers failing to thin
The advantages in thin
ling the fruit on heavily laden trees
iced not be discussed here, but at
ention is called to the Importance
II removing the wormy fruit from
he trees. This not only accords
With good orchard practice, but pro-
'ides against the maturity of the
worms in proportion to the thor
'ughness with which the work is
one.
Screening Storage Rooms.
In point of time the screening OF
forage rooms for fruit and fruit
oxes or other containers is the
asst of the supplementary measures.
t is, in fact, measure the princi-
al advantage of which consists in
diminishing the codling moths for
he benefit of the succeeding crop.
Comparatively few of the insects
ucceed in passing the winter in
yell cared for orchards The worms
Ihich have the best chance for pas
ing through the winter in safety
re found in cocoons spun in cracks
