THE COTTON AND
CORN BOIL WORM.

IuhN Bull WORM.
A fawn eolaHal moth which tlies
With 4 sort 0f a ierky motion is the
insect which laws the eggs that pro
1uce the worm in cotton known as
he boa worm, and the worm in the
terminals Of corn ANA sorghum stalks
snown as the bud worm. and i'm the
aars of corn known as the corn ear
worm. This moth flies between sun
down and dark IT is at such a time
that 1t takes food from blossoms BY
means Of it's long rrohoscis and lays
eggs on the food plants mentioned
Each female deposits from five hun
ired to three thousand eggs which
hatch into worms within few days
after being deposited When the
moth lays it's eggs IN cotton field 1t
deposits about twenty-eight per cent
Of them on the cotton squares. AS
soon as the eggs hatch, the worm
seeks food material and if 1t is on a
square 1t is lik ~ to puneture the
square sufficiently in taking one meal
TO Cause the square to drop and fan
TO the ground The cause Of shedding
is often enormously attributed to
many other agencies. Oftentimes
numerous squares will fall from the
plants soon after a wet spell, and Of
course wet weather is likely to be
given as the reason The motas,
however, generally appear soon in the
proper stage Of development OIL
course. soon after the moth appears
the eggs win be deposited, and shed
ding Will result to remarkable
extent
in this state we have three or four
1roods Of the boil worm per year
The appearance of each brood de |

This year the weather conditions are |
such as to prevent q normal develop |

Which fact we find That instead or the t
bird brood being present, now as Is
generally the case at this season,
