drosophila suzukii/spotted wing fruit fly

Anybody in Oregon, Washington, California (or elsewhere) being impacted by this bug? Trying any control techniques? Any information of what the predators are? Wild blackberries are likely a major overwinter reservoir for them.
This is a new pest that doesn't prefer to wait till the fruit is over-ripe like other fruit flies seem to, so this is especially of concern for people marketing their fruit.
As for me, good thing I'm not a vegetarian.  But they're definitely not my preferred form of protein.
