Could it be boisduval scale in its immature form? They look like patches of
white fluff. Do you have any signs of the adult (1/8" small brown, shiny non
moving domes on leaves or stems?) If so.... you have got trouble!

The link above gives some information.

Hello everyone!

i just found on one of my Phal some mealy bugs. That looks like
cotton-wool
like substance on the flower spike and under some leaves.

According to theGuide to growing Orcjids by Wilma and Brian Rittershausen,
I
should use denatures alcohol to get rid of the bugs.

Can I use rubbing alcohol, isopropylic alcohol 70% ?

Thanks

Claude
