Curtailment OF the sowing o

OF the extension division OF the Okla
homa A. and N. college. expressed
In a letter received today by A. n
Houston. county agricultural agent
This Is urged In the face OF probable
destruction by the green bug pest
which is prevalent In southwestern
Oklahoma. II was stated.
Although Investigations have been
made, no green bugs have been
found in Grady county. Agent Iious-
ton said this morning.
Following is the letter received
by Mr.. Houston from Director James
A. Wilson:
County Agents, II. +. Waters Of
Marietta. Clyde McFeaters OF King
fisher. and II. Garland OF Cordeli
have sent specimens OF green bugs
to the chronological Department OF
tho College. Other county agents
have sent specimens for Identified
ton believing them to be green bugs,
but they were in each case duly in
formed.
The present infestation therefore
feems to be in the southwestern part
OF the state. 1 believe however that
II Ia generally present over the
southern half OF the state. They have
ruined the wheat in Grayson, Collin.
Ellis, and McLennan counties o.
Texas.
These conditions are almost pre-
cisely the same as during the out
break of 19O6-7 when they de-
stroyed all the wheat and oats In
Texas, Oklahoma and nearly all OF
1t in Kansas. | have been unable to
inspect the field conditions in Texas
so as to know definitely the status
OF the parasites but | conclude from
what | hear that the parasites are
more abundant than during the early
spring of 1907.
"At the present time in 1907 there
was little o no damage in Okla
homa. By the middle of April how.
ever the damage was complete. The
parasites overlook the Green bug
throughout Oklahoma about the
tenth of April. About the 18th OF
April it turned cold and was cold
for a week or ten days. so that the
parasites were unable to develop.
They must have farm weather for
development. The green bug pro-
duces the young alive and can null
tiply under the snow If it has plenty
of food.
ELEVEN and a half days is. the
time OF Green bug develop
ment. During warm weather less,
and in cold weather longer. Forty
three days is the average life of
the green bug. Sixty days is the aver
age number of young produced by a
green bug. 222 sextillion, 1853 quin'
tillion, 713 quadrillion, 969 t%rillion.
919 billion, 1928 million, S9S tho1s-
and, 212 would be the number pro-
duced by one female and her pro-
genccy within six months if not ham,,
pered in any way.
MY advice is to curtail the SOW
ing Of small grains to a minimum.
This will be my advice until I
konw whether the parasites are con-
trolling the green bugs or not. When
the control begins it may be recog-
nized within one or two days after
starting. If this cold weather con
it will not begin until the
and oats have been destroyed.
"Tde food plants OF the green bug
are wheat, oats, rye and barley. Rye
and barley is less affected than
wheat or oats. I have had but little
experience with barley and cannot
say definitely whether they may kill
or not, but believe that they can.
corr and a few similar plants
will suffer most in extreme cases
but are generally not seriously in,

prevailing south winds. They are
