INSECTS AFFECTING THE CHERRY. 



INJURING THE TRUNK. 



The Flat-headed Cherry-tree Borer. 



Dicerca divaricata. 



This insect is closely related to the Flat-headed 

 Apple-tree Borer, to which it is similar in life-history 

 and habits. The adult, a handsome, brassy or cop- 

 per-colored beetle, about four-fifths of an inch long, 

 deposits eggs during the summer on the trunk of the 

 wild and cultivated cherry. These eggs hatch into 

 larva- that bore through the bark to the sapwood, 

 upon which they live. They gradually grow larger 

 until, when full grown, [they resemble Fig. 10 a. 

 They then pupate, and shortly afterwards again 

 change to the beetle state. 



Remedies. — Fortunately this borer is rarely seri- 

 ously injurious. Should it become so, the treatment 

 recommended for the Flat-headed Apple-tree Borer 

 would be also applicable in this case. 



INJURING THE LEAVES. 



The Cherry Aphis. 



Myzus cerasi. 

 The twigs and under surface of the leaves of the 

 cherry are frequently thickly infested during May
