G&G QT

Usually I just see a black hole that something has come out of, I never see the something. I find that most of the apple then is still edible as mainly the core is affected which I don't tend to eat. You do need to use a knife to eat them then. If you have lots of tiny maggots, I would think that is something different. If they are very small, it could be a type of fruit fly. I've had fruit fly damage on cherries this year with about 20% of the crop affected, and then some on nectarines. Almost certainly the dreaded Spotted wing drosophila and some of my apples seemed to have similar damage.
