What pesticide are you using?

Some like imidan, have a kickback ability which means it will still kill the bugs after they are inside the fruit.

I just asked a similar question in another thread with a picture attached. No one has answered yet but you may find what you're looking for if someone does. Look for the thread with kickback death in the title

Thanks Bart.

I used triazicide and immunox on the apple trees. Just did my 2nd spray on Thursday morning and one maybe two weeks ago. My apples look a lot like yours in the other thread. It would be nice to guess right while thinning which ones will survive but maybe i just need to experiment myself and cut some open and look for larvae.

Sharppa, crescent shapes are more likely egg laying; round wounds can just be feeding bites. Also look at how deformed the apple is overall. The more deformed the further the PC got in it. Also if the wound is oozing at all its surely a bad one, thin it.

I was thinning last night so I was making those decisions. Fortunately in nearly all spots I could thin all the PC damage and not lose anything, but in a couple spots I had to make decisions. My Hudsons Golden Gem gets absolutely nailed every year, not sure why.
