SUMMARY. 



Spray the tree with Arsenate of lead or Paris green when the 



leaves are about half grown in spring. 

 Repeat this treatment soon after the eggs hatch — usually about 



the first week in June but varying with the season and 



locality. 

 Remove all loose bark on the trunk and main limbs of the tree, 



that the grubs may find no place to pupate in, and so go to 



the base of the tree. 

 Destroy the grubs and pupa^ at the base of the tree with boiling 



water, kerosene emulsion or the kerosene and water mixture, 



and repeat after five days if necessary. 

 Destroy all beetles found in hiding during the winter.
