The codling moth or apple worm
is familiar pest to every grower
or consumer of apples, and wormy |
apples, the result of its work,
scarcely need description The
larva, living most of its life with
in the fruit, throws out through
it's entrance hole, which it cnlargcs
srom time to time, or through its
exit hole in the side of the fruit,
the characteristic mass of frass or
'excrcmcnt which is the sign of in
Hesitation. Such an apple is Prac-
tieally unstable or, at best
fetchcs very small price, either
for consumption or for working up
into cider. The monetary loss thus
occasioned by this insect is greater
than that due to any other insect
pest affecting fruits
1t has been shown by careful cs-
Inmates in various apple growing
states that this insect may cause a
loss of from 20 to 30 per cent of the
fruit which would otherwise be
sound and interchangeable. Without
going into details, this loss, on
the lowest or 20 per cent basis,

in the United States, and this does
not include the expenditures for
spraying the trees with, an $S,-
5000 additional, indicating a
total loss chargeable to the codling
moth of nearly $40, 900, 900. Great
as this loss still is, it has been very
much limited by measures of con-
troll which are becoming more and
{ more widely adopted, as many apple
growers in badly infested regions
are now saving every year more
than IS per cent of fruit which
would, without treatment, be
wormy.
The original home of this insect
was probably southeastern Europe
the home of the apple, but it ha;
ton of the apple until it is no =
found in almost every country il
the world. 1t is spread principally
by the shipping of the infested
fruit. The young larvae in sucf
fruit complete their development
and leaving the fruit spin Cocoon'
on the crates or nearby, the moths
emerging in due course and flying
TO the nearest orchard to deposi
sheir eggs. When orchards are blu
a little distance apart the moths
may fly from one orchard to an
other.
The apple is the natural food o
tbis insect, and sustains almost al
the loss occasioncd by 1t. Pears ar
next in order for infcstation, but i
Ehard pears are usually not badl,
infested. The codling moth larva'
have been found also in the fruit o
ounce, prunc, plum, peach arit
cherry, but never in sufficient mum
bers to cause any great injury.
In fighting the codiing moth tn,
first thing to do is to destroy al
larvae before they have time to be-
come moths. The store rooms o
other places where apples hav
been Ike pit should ee gone over an,
all the larvae destroyed; rubbish
and trash should be removed from
the orchard and burned all boxc
and other places where the worm
might hide should be thoroughly
examined and the worms killed
