Several years ago in Palo Alto we had mites that were destroying our fuchsias and Eugenia hedges. Santa Clara County introduced a wasp or some other organism into the atmosphere. I believe that the control was effective. My son has a Eugenia hedge that is flourishing now. My orange trees do not seem to have as many white flies. I do not know about the fuchsias; I gave up on mine.
I hope the scientists are going to try the wasps or some predators to try to attack the mites.
Evidently, the bumble bees have not been affected by the mites; so if our honey bees become extinct, we may become dependent upon the bumblebees for our crops.
