this is definatly mealy bug.
i work in a garden center and thats what it is.
the only way to get rid of them is to hose off the plant every 3 days with water and dish soap if its a bad case if not you have to dab the bugs with rubbing alcohol, the best thing to do is to just get rid of the plant and get a new one. the bugs spread like wild fire.
hope this helps
