and June; and lie says experience teaches that after a chincli-bug 
season we cannot, the next year, argue immunity from damage by 
these insects from any peculiarities of the winter. 
LeBaron, Wm- Lecture on Insects. (Fourth Ann. Kept. Board 
of Trustees Ill. Industrial University, 1870-71, pp. 176-180.) 
The chinch bug furnishes the most remarkable example on 
record of the efficacy of climatic influence in exterminating noxious 
insects. The chinch bug delights in dry, hot weather. The rainy 
season of 1869, embracing the month of June, which is the chief 
feeding and propagating season of these insects, almost extermi¬ 
nated them fiom Illinois; but they are again becoming numerous, 
ind in some localities there is reason for the gravest apprehen¬ 
sion for the spring wheat crop of the coming year. In those dis¬ 
tricts where they were numerous last fall, sow sparingly of spring 
vheat next year, and get the seed into the ground as early as pos¬ 
able. Burn corn stalks and other litter that lie about fields and 
ences. It is not probable that these insects would ever multiply 
o any great extent if spring wheat were not cultivated. They at- 
ack barley, but will not eat oats unless compelled to [?]. Winter 
ye, like winter wheat, is too far advanced in early spring, in this 
>art of the country, to be much injured by them. Corn does not 
asily succumb to them, generally only a few rows being injured; 
ometimes, however, whole fields are laid waste. These insects gener¬ 
ally migrate on foot. Furrows plowed across their path, or boards 
et on edge and smeared with coal-tar have been used to arrest 
heir progress. The efficacy of all such methods will depend on 
he thoioughness and ingenuity with which they are carried out.
