6 FARMERS’ BULLETIN 657. 
breaks have been traced directly to woodlands bordering upon the 
fields (see fig. 5), the chinch bugs beginning their destruction along 
the margins of the fields nearest to the woodlands, haying passed the 
winter among tlie fallen leaves or among such clumps of broom sedge 
as had grown up among the trees and brush. So, too, have destruc- 
tive outbreaks in the Middle West been traced to the matted grass 
and fallen leaves bordering hedges of Osage orange by roadsides and 
elsewhere. The farmer must understand that it is to such places as 
these that the chinch bugs flock in the fall, and whatever measures 
he can apply to prevent them from wintering about his fields will be

just so much protection to his crop from attacks of their offspring 
during the following year. 
In the timothy meadows of New England, New York, and northern 
Ohio these conditions are of less importance, because there the 
insects pass the winter largely in the meadows and can not migrate 
to or from these places, except on foot. 
Chinch bugs will stand almost any degree of cold, provided it is 
continuous and they are fairly well protected from sudden changes. 
And the farmer may be able to take advantage of their hibernation 
to deal disastrous blows against their occurrence in his fields during 
the following spring and early summer.
