    I have a couple of quite old (40 yrs?) grapevines that are productive and appear quite healthy. This year I have noticed that some of the leaves and shoots are displaying a small round gall, inside of which there is a tiny yellow-orange worm. Is this a problem and if so can I do about it? Any ideas?
