That's a bird peck or some other physical injury that's starting to rot.

Found my answer...it is caused by a codling moth just before the fruit is ripe.

It happens in the SW during July and Aug. but can happen earlier depending on the area.

Thanks fruitnut for your responce

I do not believe that is Codling Moth damage. If it were Codling Moth that hole would not be 1/2 inch deep. It would lead to extensive tunnelling filled with frass and possibly still with the larva in situ. There are sometimes 2 holes - entry and exit - or sometimes the caterpillar leaves by the hole it came in by. Furthermore the pear appears to be a good size and ripe. Usually CM damaged fruit drops early. Also I've never seen rot around a CM hole.

I agree with fruitnut that it is a physical injury from the outside.

Nope sorry......the pear is not ripe yet it is still very hard at this point(needs to ripen 4-5 more weeks)) At the time of the above post the pear above had just been picked off the tree along with the 30 or so others that we lost. After inspecting and cutting open some of the other pears we found the trail leading to the center with frass. It also seems that as the pear ripens and develops its sugar, in dark cool storage the holes start to become larger with the black area surrounding the sting becoming larger. Thanks everyone...

Aha - well if you found tunnels I'll retreat gracefully. Didn't have that information previously.

UK not your fault @ the time of the first posting we had no clue
