It looks to me like some kind of scale, but its not a species that I have seen before. I bet there is an insect inside each tiny waxy capsule. Can you get a "super macro" closeup shot showing the fine details a little better? I would isolate the plants, maybe submerge them for a few days, scrub the pests off with a toothbrush or cotton swab using water or rubbing alcohol, then spray with Orthonex.

Thanks Walter, I think it is a scale also. Unfortunately, that's about the best macro my camera can do! I'm surprised how thickly it is infesting this plant. A local (Thai) agri-chem supplier has recommended clopyrifos and flora oil as treatment, saying she has used both on Platyceriums without adverse reactions and that the 'flora oil' will kill any eggs. It's always hard to find the Thai-available equivalent of the compounds generally used by you guys in the West, this is compounded by the fact that I'm not in/near Bangkok or a major city.
