I've diagnosed the problem I've been having with my phalanenopsis/doritis
leaves as thrips (confirmed at orchid society meeting). What's a good
treatment to get rid of the little sapsuckers?

Fortunately, any decent insecticide is pretty effective against them.

Favorites in my orchid "medicine cabinet" include Orthene (acephate) and
Merit (imidicloprid). There are a few "Bayer Advanced" formulas available
at places like Lowes that contain the latter.

I am also a big fan of insect growth regulators (IGR) like Enstar II
(s-kinoprene), which work by preventing the maturing of all stages of insect
growth. No maturation = no reproduction = death of the population, with the
added benefit of not allowing the possibility of resistance development and
the emergence of strains of insects immune to insecticides.

In truth, when I am forced to resort to the "big gums", I often mix Enstar
II with one of the two insecticides I listed.

Hardware stores around here sell acephate as "Ortho Systemic Insect Killer".
It is a cocktail of Orthene and a miteacide. Label says that it was
formerly "Isotox", but I bet it is not the same Kelthane. I could not find
straight Orthene in the stores I checked.

For Richard's problem I think the miteacide is a good idea any way. I do
not know thrip problems on Phal leaves, but maybe that is because this time
of year I am always on the lookout for thrips and thrip damage on the
flowers.

Its miticide is Vendex (fenbutatin oxide) not Kelthane (dicofol)
