The Chinch Bug and Its Control. 83 
Bugs may be trapped along barrier lines by laying 8-inch sections 
of green cornstalk close to the line 6 inches to 6 feet apart, depending 
upon the number of bugs, then quickly tapping the bug-laden pieces 
over a bucket half full of water overlain with a film of coal oil. The 
bugs should be collected in this way as frequently as their numbers 
on the stalks seem to warrant. The pieces of stalk will continue at- 
tractive for two or three days. 
The barrier work should not be substituted for an aggressive all- 
year campaign, but should be regarded rather as a play for time on 
the part of the grower. While many bugs are killed by the proper 
care of barriers (their numbers being estimated in bushels where 
catches in post-holes have been most successful), at best the barriers 
leave large numbers of bugs alive to migrate anywhere except across 
the barrier, and some will even succeed in crossing unless the greatest 
care is taken to keep the barrier line free from trash. 
PLOWING THE BUGS UNDER IN WHEAT STUBBLE AND CORN. 
With the harvesting of the small grains, spraying or deep plowing 
of the stubble should be rushed before the last of the bugs have left 
the “pigeon-grass ” and other green grasses growing in the stubble 
field. In case some of the bugs have succeeded in starting an infesta- 
tion on the first few rows of corn and the latter is small enough to 
plow under completely, it is best to sacrifice those several rows by 
plowing them under. Plowing should be at least 7 inches deep and 
the ground should be immediately dragged and rolled, to compact 
the soil so that practically no bugs can escape. It is possible in the 
ease of a small field, where the corn is too large to plow down and 
there is no spraying equipment available, to destroy the bugs in 
heavily infested first rows by cutting and submerging the corn 
quickly in a tub of water coated with one-fourth inch of coal oil. The 
plants must be handled gently in cutting and lifting over the coal 
oil, as the bugs will drop to the ground on comparatively slight dis- 
turbance. 
Under favorable conditions, a second brood of bugs usually occurs 
in the corn, resulting in prematurely deadening the stalks in late 
August, or in September. As quickly as the crop is harvested, plows 
should be started on the fall clean-up, overtaking as large a propor- 
tion of the winged adults and nearly mature young as possible, before 
they leave for their winter quarters. This completes the year’s round 
of opportunities for chinch-bug destruction. 
COOPERATION. 
It may be observed from the foregoing recommendations that the 
destruction of the bugs at every period of the year, and by every 
known practice, has been advocated on the basis that the best means
