All you have to do is stop the ants from climbing in the tree. This is not 
an "old wives tale". Ant are aphids farmers and protect them against natural 
predators. Without ants, aphids don't do too well usually, not enough to do 
noticeable damages to a tree.
You can surround the trunk of the tree with a wide band of masking tape or 
other material, and on this tape put a ring of Tanglefoot (not directly on 
the bark of the tree is the idea). The ring of Tanglefoot should be 
continuous and wide enough (at least an inch) so that the ant cannot build a 
bridge accross. They do this by sacrifycing their own, when the obstacle is 
not too large... Make sure they cannot get under as well....
You will find that the population of aphids won't last long without the ants 
to support.

Good luck, Please let us know the results,

Hélène, zone 3-4, north of Ottawa
