We have a Concord (?) pear, which can produce very tasty, juicy fruit

The last 3-4 years, as the fruit begins to ripen, wasps start eating the
fruit just at the base of the stem - fruit then rots and/or drops off.

Any suggestions for preventing the little black and yellow ^&%*£!! from
doing this.

You just have to pick them just before they are ripe.
