Those look like the regular kind of worms I get every year. They eat through the stems and kill fat buds and cause a lot of mold. I hate to keep touting Safer but there products are listed as omri organic and they have a specific product that will kill these worms. You have to spray as soon as you see the first worm and may to do some additional spraying.

In my crop in my yard (12 plants) I check for worms every day. If I find them I feed them to my chickens. At my property in the hills I never see any worms, spider mites or other pests. I occasionally see powder mold but that is rare in the mountains.
