The old bug eats little hole into
the kernel and zthen 4 deposits her
egg in: this little hole. The egg hat
ches into a little worm which eats
out the inside Of the grain leaving on
" the shell. This worm then chan
ges to a little dark bette which eats
its#way out&and later starts laying
eggs at the rate ola hundred eggs for
each adult female. Seldom more than
one egg is laid>in one kernel. It-takes
less than a month from the time the
eggs are laid until the adults are full.

These weevil are common in the
south and were probably shipped in
with grain The mild winter and the
extremely hot weather Of the past
few months have been favorable to
these hugs. ~.::'< -. :
Cars Of grain shipped =. containing
these WeeVil alive, no matter now
good the: grain, u.s., will be cut to sam
pie grade. This means a%lOss Of $75
to 500 per car. Many of the: eleva'
tor men did not know their elevator
was infested until. they received re.
turns after the grain: was; shipped. =
Livery farmer; should see that his
granary is free of bugs SO as to- get
more for his grain. and protect his
seed grain for next year The >eleVa'
tors do not want grain with bugs in 1t.
The bugs cannot be detected p ny
looking at the grain in the bin as they
keep away from the light. To inspect
old grain take coarse screen that
will just keep the grain from going
thru and screen some OF the gram
from down in the bin or from a dark
corner. Catch. the screenings on a
bag or paper and watch for few
minutes. If there are any Weevll pres
ent they will start to crawl. Another
way of detecting the presence of wee
vii in grain is to take a shallow dlsh'
partly fill, with water settle dish IN
grain and cover with bag. If Weevll
are present they will he attracted by
moisture and dark place., .
If weevil or bugs of -eny kind are
found steps should be taken to get
them under control. Bran bugs and
other insects if present in grain will
reduce it's value when offered to1
sale. If possible all the. old grain with
bugs in it should he removed from
granary to protect the new grain: The
empty bins should be; swept out clean
and sprayed with formalin, gasoline
or carbon disulphide Cast: two, ex
plosive.) :,
If the bin infested is full of grain il
may he fumigated to>kill the bugs and
eggs. The bin and room should Dc
closed up tight. Use sever pounds OF
Carbon disulphide or fourteen pounds
of Carbon tetra Chloride to 1000 cubic
feet of space Sprinkle over grain OF
put in shallow dishes on top of grain
Cover grain with bags, carpet or pa
per. The gas given off is heavier thar
air and will. penetrate the grain. kill
ing bugs and eggs. Should be LEFT
closed up for at least twenty :; foul
hours. Care should be used in hand
ling carbon disulphite as it is explo
sive. :,
Cases where weevil are found shoult
be reported to the town board ant
the places cleaned up. .
The county agent and the centra
committee will act for the county.
+ It is only thru united effort and ev
eryone doing his part that we will bt
able to keep this insect under control
A copy of this information and spe
cimens Of the weevil should be: pre-
scented at each township meeting s.
that everyone may become familia
with the waevil and he enlisted in thu
fight to keep it under control. =
