My horses are kept near a pond, and we have these awful little gnats that are basically invisible but cause the horses to scratch like crazy unless we put bug spray on them, so maybe it's something like that for your horse's tail? As for the mane, the only thing I can think of is a different type of fence. Maybe you could put up a strand of hotwire along the existing fence?
Peace, Love, and Ponies of all shapes and sizes.
