Yes the PC gets crushed by apples and pears as they grow. The only exception I have seen to this is some crabapples can mature a PC, also occasionally flukes happen where one will grow to maturity in an apple… it is extremely uncommon though. If you don’t have too many bites the fruit is completely edible, the only issue is the ugly looks.
I am now eating the few Yates I have left over from last year (perfect now, by the way) and I am noticing a fair number have curc bites in them. I thought I had thinned out all the bitten fruits but I still missed quite a few.
I finally did my first curc spray last night. It is nowhere near the warm temps for the curc party, but there is at least some activity if the temps are around 70 at dusk. I found a few spots on my plum trees with infestations. Still, 99+% of the fruit is untouched… I felt like I was living in California looking at all the perfect fruit without any sprays
