I have no clue, Patty. I have always seen/had the scale and mealy bug problems. I don't mean it is a regular problem, actually quite seldom, but IF I have ANY orchid infested, it has always been in the Phal. family. Having had so many orchids over the last five years (certainly over a couple thousand), I guess just the shear number lends itself to seeing some sort of pests. I never see any pests on my Cattleya alliance plants though, and that is by far what I have had the most of.
