THE WHITE PINE WEEVIL 

 (Pissodes strobi) 



Figs 1 and 2. Young white pines with the terminal shoot killed by the 

 white pine weevil. Such a condition is disastrous to the future development 

 and symmetry of the tree. 



Fig. 3. A general view of the areas regenerated by white pine seedlings 

 on the slope of Little Mountain, near Mentor, Ohio. On this slope fully 90 

 percent of the young trees had had the terminal shoot destroyed.
