Summary. 



From the above we mav briefly summarize as f-ollows: 



Tlie peacb-tree borer {8. €a;itios(^ is a native American species. 



It was originally described in 182;>, at which time it was an 

 important pest in many of the peach-growing sections of the 

 country. It is now widely distributed throughout the United 

 States. 



The parent insects are beautiful moths. The eggs are laid on 

 the trunk of the tree, usually near the crown of the root. 



The injury is caused by the larvae, which attack the roots, and 

 occasionally the trunks of the tree. Their presence is indicated 

 by the exudation of sap from the wound. 



The pupae may be found in the infested roots, in the sap about 

 the roots, or in the ground a short distance from the roots. The 

 moths usually appear in a week or ten days after pupation has 

 taken place. 



In this climate the insect passes the winter in the larval state. 

 There is but one brood annually.
