Unfortunately, lady beetles have not proven effective against this insect,

Do you mean in this tree. or in general? I have, in fact, seen lady
beetle larvae sucking the juices from aphids. Perhaps you are saying
they don't do enough damage to make a significant difference?

At any rate, I would think it's worth a try (along with lacewings, or
maybe the lacewings without the lady beetles). My goal was simply to
suggest a non-chemical approach (and less expoensive solution than
spraying a large tree).
