The moth Of the apple worm las
the eggs from which the larya az
, developed. It is rare to find more thai
one egg on any apple, pear or ounce
or more than one l4rsa. Hence, !
only few winter Dests are preseI Tet

in a few days, the length OF time
depending OF tins warmth oil
the season. sometimes fruit grow
ers have been disappointed by finding
the codling msth in their orchards,
although they have made attempts to
scrape off the winter nests and de-
stroy them. This has arisen from 4
lack OF csrs in burning the enemy.
There must be no quarter given; to
leave only a few enemies on the field
may entail destruction on the fruit
crop, 60 wonderfully prolific are these
creatures.
The moth belongs to the family OF
Tortrices; the worm is the larva Of
the Csrpocapsa Pamonella THE cod
ling or apple moIh). 1t isI
not By any means the only
enemy man has in destroying the
apple, but it is the most
effective in attacking and Destroying
the fruit. 1t is itself the subject OF /
attack by parasite, which eats into
and destroys the lsrvs; this enemy of |
the apple worm is species OF chair
worm," the Mernis Accuminaia
mentioned BY Packard in the report
of the chronological commission.
1t hss been found that the codling
moth is attracted by placing Eight in
the vicinity OF apple trees, into which
the creature flies and is consumed.
Large numbers of lepidopterous
insects may be captured and
Destroyed in this way. But the
most effective method appears TO
be to offer an inducement to
children to seek out the nests OF
arva, and pay them Per capits for
heir osptives. 1t ia surprising what

With regard to the destruction OF

lifted that their numbers are, to CT

mankind; butt mu.t also be borne OIL
mind that the bird can only reach II

)geriess to touch the moth when
le latter is in the apple The fact
lat the bird is unable to cope with
