Sounds like aphids. They suck the sugary sap that the leaves produce, and excrete what they can't digest. The ants are farming them for their excretions (honeydew), so they protect them from predators, and move young ones to new growth and other trees. Sometimes all that is needed to remove the aphids is to stop the ants, so the predators can get at them. Sometimes it is necessary to spray the aphids with insecticidal soap, or diluted organic washing up fluid. Aphids rarely stop a tree from bearing though, so something else must be wrong. Did it bloom this year, Ps?

Tiny green balls about half to one and a half times pinhead size? Or bigger?
