INSECTS INJURIOUS TO THE PEACH, PLUM, CHERRY AND STONE 



FRUITS * 



The Peach Borer f 



WHEREVER peaches are grown they are subject to the attacks 

 of the ever-present borers, and if neglected will soon succumb 

 to their injury. East of the Rocky Mountains the common peach- 

 tree borer has been known since the earliest settlements, and it 

 also occurs in Colorado and Oregon. It is a native insect which 

 probably lived on wild cherry and wild plum, and is known to 

 attack plum, prune, apricot and nectarine, though chiefly a 

 pea'ch pest. On the Pacific Coast a nearly related species, the 

 California peach-tree borer,:}: does similar injury and has very 

 similar habits. The lesser peach borer is commonly associated 

 with the common peach borer and has done considerable injury 

 in western Xew York, Maryland, Virginia and Georgia. It occurs 

 throughout the country and is doubtless commonly confused with 

 th larger and more common species. Although it is quite different 

 in its life history and habits, the injury is very similar, and as it 

 must be controlled by the same methods it need not be separately 

 considered. 



The presence of the borers may be detected by the mass of 

 gummy, gelatinous material, more or less "mixed with soil, which
