THE APPLE SUCKER. 



If this treatment is persisted in I think the pest will be held in 

 check, but it is most important that the roots of the trees should be 

 treated as well as the branches. 



Spraying in the Autumn is of little, if any, use, for as fast as the 

 trees are cleaned, winged females from trees in other orchards re-infest 

 them. 



THE FRUIT TREE ROOT LOUSE. 



Schizoneiira fodiens, Buckton. 



Early in the year a Worcester correspondent forwarded specimens 

 of this insect, from the roots of Red Currants, and later I received 

 it from the same county on the roots of a young apple tree. 



It has long been confounded with the root form of the Woolly 

 Aphis (Schizoneiira lanigera.) 



In the first case Vaporite was employed and proved fairly 

 successful ; later, in the second case, experiments were made with 

 Apterite which proved most effective. 



THE APPLE 5UCKER. 



Psylla mali, Schm. 



Experiments with the Vi and V2 Fluids have been continued on 

 the eggs and larvae of this insect, and most satisfactory results have 

 been obtained.
