As a beginning apple grower in New England, with a small orchard of 
dwarf trees, what do I need to know about apple borers?  I have put up 
window screen cylinders with foam collars to keep borers out, and I am 
willing to scout the trees regularly.  However, I don't know how big a 
hole I should be looking for.  Any one have any recommendations for how 
to deter and how to recognize borer damage in apples?
