I can send it by Email if requested

Do the fruits take on a 'waisted' or 'guitar' shape? Are there gaping cracks
or small holes in the fruits? If so you may have Pear Midge. Typically the
fruit will have a funny shape as mentioned and a blckened crack will open
up around part of its girth as the grubs break out and drop to the ground.

You could break open a few and look for grubs, though if they have holes or
cracks in the grubs have typically gone.

Andy.

Your description is spot on for what I have. Can you suggest a spray schedule to control Pear Midge. I gave the trees a tar oil winter wash in Feb and have sprayed a couple of times with a general insecticide in the spring.
