THE CHINCH BUG. TF 
years, followed by wheat, would have amounted to precisely the 
same remedial measure as the one suggested. 
A case in northeastern Ohio has come to the writer’s notice where 
an infested timothy meadow was plowed late in the fall of 1897. 
Late in April of 1898 this ground was cultivated, rolled, and har- 
rowed several times and most carefully and completely prepared 
for corn, which was planted, but with the result that a portion 
of the field was attacked and destroyed by chinch bugs, largely 
of the short-winged form. An examination about June 10 revealed 
the bugs in considerable numbers about the plants still remaining, 
but scattered over the field were more or less numerous clumps of 
timothy, in some cases apparently killed by the chinch bugs, while 
in others the bugs were literally swarming about the dying but still 
green clumps of grass, thus showing that they had either not been 
buried by the plowing and cultivation of the ground or else the 
grass had not been thoroughly covered, and thus ladders had been 
left whereby the bugs were enabled to climb to the surface. 
SUMMARY OF REMEDIAL AND PREVENTIVE MEASURES. 
In summing up the matter of remedial and preventive measures 
for the control of the chinch bug, it may be stated that the insects 
can be destroyed in their places of hibernation by the use of fire. 
They can be destroyed while in the act of migrating from one field to 
another by barriers or deep furrows supplemented by post holes and 
by burying them under the surface of the ground with the plow and 
harrow, or the latter method may be applied after the bugs have been 
massed upon plats of some kind of vegetation for which the bugs are 
known to have a special fondness, these decoy plats being so arranged 
as either to attract the females and induce them to oviposit therein 
or to intercept an invasion from wheat fields into cornfields. When 
these decoys have been turned under with a plow and the surface 
immediately smoothed and packed by harrow and roller the bugs will 
be destroyed, while in the cornfields they can be destroyed on the 
plants by the application of kerosene emulsion. Without vigilance 
and prompt action, however, only indifferent results are to be ex- 
pected from any of these measures. 
There are several spraying materials which can be used effectively 
against the bugs after they have congregated on the young corn, but, 
unfortunately, most of these are injurious to the plants. Kerosene 
emulsion of 5 per cent strength will generally kill the bugs and will 
not always injure the corn. The stock solution is made by boiling 1 
pound of good lye soap in 1 gallon of water, adding this to 2 gallons 
of kerosene, and stirring the mixture with a paddle for 5 to 10 minutes. 
A better way to stir the mixture is to put the nozzle of the spray in 
the vessel and pump the liquid back into the vessel for five minutes. 
Dilute the mixture to a 4 or 5 per cent solution by adding soft 
water. Some of the proprietary spraying materials and cattle dips
