My trained pear tree fruits well but every year, small holes, up to a centemeter in size, appear in most of them, near the stalk, causing them to rot and fall off. Is this caused by birds or wasps, and what can I do about it? Many thanks for your replies. However I know that it is not codling moth, as this would be maggot damage from inside, which this is not. I have clean holes, about 1 cm diameter, near the stalks, from the outside. The inside of the pears is clean.
