THE PAINTED HICKORY BORER 197 



Infested material which cannot be used by the manufacturers should 

 be utilized as soon as possible for firewood, preferably before the insects 

 have had time to emerge. In this way large numbers of them may be 

 destroyed. 



All material which cannot be used, such as slashings, should be burned 

 as soon as possible, for it is in such places that the insect finds excellent 

 breeding places. When such useless mater al has been left in the woods 

 until it has become infested, it should be burned before the beetles have 

 had an opportunity to emerge the following spring. 



The destruction of Crataegus in the vicinity of large tracts of hickory 

 would also be beneficial, in that it would destroy the food supply of the 

 adult beetles at the time of emergence. The elimination of such trees 

 would be beneficial in any case, as they are the native hosts of many 

 of our most injurious insect pests.
