Just real worms like Annelids, earth worms, not insect larvae.

Some of the simple worms will regenerate. A prime example is the planarian, which can essentially be chopped up and almost every chunk will become a new worm. If the head is split, each half will regenerate its mirror image and the worm will become 2 headed. A split tail will create a double tailed planarian.
However, earthworms die after they're torn in half. They're much more complicated critters than the flatworms, and if you use a half worm on a fishhook leaving the other half in the bait box, the entire batch of bait will be killed within a day or so.

Certain flatworms, particularly free-living ones like Planaria, can regenerate very well. If you cut them in half, you eventually get two complete new animals. But calling these animals "worms" doesn't indicate any close relationship to other animals we call "worms", such as roundworms and segmented worms. These two groups of animals do not regenerate. If you cut an earthworm in half, the posterior half will die. The anterior half will often die as well, but it could possibly heal without regeneration - just like cutting an arm off a man.

Earthworms, can regenerate the lower part of the body if cut off, but the severed lower part will just die.
Flatworms, especially planarea, can be cut into multiple pieces and each of those pieces will form a new individual.

none do. from what i remember from biology in high school. worms if they are cut below the band they may live a while but they dont regenerate that way

I don't think earthworms do regenerate. However a tapeworm would since it is composed of a series of individuals.
