were protected throughout the winter, migrating from them in the 

 spring and spreading over the wheat field. In other cases destructive 

 outbreaks have been traced directly to woodlands bordering upon the 

 fields, the chinch bugs beginning their destruction along the margins 

 of the fields nearest to the woodlands, having passed the winter 

 among the fallen leaves. So, too, have destructive outbreaks in the 

 Middle West been traced to the matted grass and fallen leaves border- 

 ing hedges of Osage orange (fig. 5). The farmer must understand 

 that it is to such places as these that the chinch bugs flock in the fall, 

 and whatever measures can be effected to prevent their wintering

about his fields in this manner will be measures of protection to his 

 crop from attacks of their offspring in 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 theinselves, and do not 

 migrate to or from these places, except to travel on foot. Chinch 

 bugs will stand almost any degree of cold, provided it is continuous 

 and they are fairly well protected from sudden changes. Thus it is 

 that the farmer may be able to take advantage of their hibernation 

 to deal a disastrous blow to their occurrence in his fields during late 

 spring and early summer.
