I don't know, but even the leaves are more attractive to insects. A 
couple of years ago, I was flicking Japanese Beetles from my grape vines 
into a pan of soapy water. I noticed several Japanese Beetles on one of 
the apple trees. It's a tree where I grafted different cultivars on 
different branches. The beetles were ONLY on the one branch grafted to 
Honeycrisp. I've never noticed them eating any other apple leaf.

Steve in the Adirondacks  (Where a bear with 2 cubs was seen at the end 
of our street today. I hope they don't discover my trees, hanging with 
apples and pears.)
