The Pine Weevil. 45 



trees by feeding upon the tender bark of the 

 young shoots. It is most destructive in 

 young plantations planted after a ripe crop 

 has been removed. Its chief breeding-places 

 are bare spaces in the woods among the 

 dead debris, old stumps, rotting bark, and 

 other decaying matter ; and if this is carefully 

 destroyed after each successive thinning 

 the destruction will be minimised, if not 

 altogether prevented. 



Finally we come to the Spruce-Gall Aphis ; 

 this is similar in some respects to the Larch 

 Aphis. The mother cherm attacks the ends 

 of the shoots of the spruce fir, and in the 

 early spring it may be fouid with the sucker 

 inserted in the base of the bud ; this gives 

 rise to the peculiar pseudo cone so oftqn 

 seen. 



When the young trees are much infested, 

 the galls should be collected and destroyed ; 

 and, if this is impossible, all the trees should be 

 cut and burned. Here the only means of 

 prevention are careful culture and prompt 

 destruction of debris whenever thinning or 

 cutting of any kind takes place.
