We have a 12 year old Honeycrisp apple tree that has had some sort of insect issue in the fruit for the past several years.
The ripened fruit has pin prick sized dots on the skin. Underneath is a light brownish colored trail, less than 1/8" in width, that is less than 1/4" deep into the apple. We have never seen any worms. When there are many dots in the same area, the fruit is deformed.
Do you have any idea what this could be and how to alleviate the issue?
Thank you.
