THE cHlncH BUG.

The chinch bug is doing. ana has
been doing in Oklahoma a great deal
3f damage Its presence Is mainly
due 70 certain crop rotations that are
practiced by the farmers. Oklahoma
IL so located that 4 crop rotation NAV
be inaugurated for controlling the
chinch bug that cannot be inaugural
ed in many other states. The best
crop rotation for the development q
the chinch bug is corn, wheat and
oats. In the spring the chinch bug
comes from its alternating quarters
and lays its eggs on the wheat and
bats A mood develops just before
the wheat and oat harvest and goes
to the corn fields where this brood in
turn lays its eggs that later deyeEor
and seek alternating quarters in the
corn stalks. corn shocks hay and
pasture lands. In order to preven,
the development of the chinch bug il
IS necessary to take a link out Of this
system which will prevent the insect
from making the complete cycle. n
Oklahoma this may be very easily
done by one farmer but unless farm
ers in the same vicinity practice
similar rotation very little will avail.
IN the FIRST place, make break II
shis crop rotation by either panting
cotton entirely instead OF corr and
sorghums, or cut out the wheat and
oats entirely for one or two years
The ehinch bug will not breed In at
talfa, cowpeas, cotton and peanuts
ANY one or more of these plants
should be substituted either for the
small grains such as wheat and oats
on the large grains. such as corn. the |
sorghum, etc. Another great factor
that should be considered in the con-
troll Of the chinch bug is the manner
of disposal OF the sodder grown on d |
'afm No better disposal OF corn and |
sorghum fodder in reference 10 the |
control of insects in general can be |
made than storing such material in |
silos Insilage OF course IS WAYS |
harvested while IL Is green and sue. |
'ulent Under such conditions It is |
literally taken away from the deyel- !
1ping insects; such excellent hiber- /
lating places as corn stalks in gen
'ral are removed entirely from the |
1eid, leaving the latter a veritable
leso!ation for the winter convenience
