Don .. I am fruitgrower and know this damage as well - it is not codling
moth causing the stone cells in the pear - that moth only cause damage on
the leaves, and even there are pesticides to get rid of it the very best
way if you don't want to do so is the try to get plenty of useful insects
and your trees in balance.
then the stone cells:
Stone cells in the pears are caused by another insect (sorry I do not know
english name!) .. but it is a sucking insect starting attach rather early
after blossom time. I guess you will find info in UCDA website .. but this
insect have to host change from other plants - raspberries and neetles are
some of the most important here by us for it to lay eggs on an d then the
nymohs clims up in the trees - one good advice is to keep the grass/weeds
under the tree low the whole growing season, so not the nymph of this
insect can so easily climb up in the trees. It is also important to have
lots of useful insect to eat these nymphs.
But pears with stone cells are not nice to east at all ... so good luck.
