In spite of your disease and insect pressure, I still envy your zone 7a
or b climate. Our family made the long trip south to spend a summer week
in Ocean City Maryland 6 or 7 years in a row back in the 90s. I always
thought I could be happy living near the bay somewhere.
Several months ago, I mentioned, here, that I didn't believe curculios
ever actually reproduced in my apples, even though they scar them up
badly in years that the weather keeps me from spraying as I would like
to. Others replied that I was right, and they don't manage to reproduce
in apples anywhere else either.
My point is, that if this is true, having neglected apple orchids in the
area would not actually increase the number of curculios on your
property. In fact, the apples would function as a trap crop to draw some
of them away from fruits that they actually reproduce in. Having said
that, I doubt the apples do enough good to say so. We can reopen the
curculio/apple discussion if need be. Have you ever found a maturing
curculio larva in an apple?
