What's eating my apples?

Had a check in my bumper book of apple fun, and it could be lots of things, but none say that there is any gunge oozing out of the fruit.

Would it be worth removing one fruit and cutting it across the hole to see if a bug is in there munching. Guess it would give a better idea of what your up against if we knew it was a bug, not a virus or fungal type disease

Sounds like codling moth at work.

if it is codling, according to the text book its early - july/august is the danger period . tortix moth is may/june and leaves tunneling holes...treatment for all of them appears to be fenitronthion (I'd put money on it being a banned sunstance if I had any spare!).
Spraying is the treatment given - mid June and three weeks later, so you might be lucky with the crop left.

Such a pain isn't it? hope you still have some crop to enjoy. What sort of tree is it - the young fruits all look the same on mine at this early stage
