Bio-Control Measures Effective contra White Fly

I'd appreciate being sent information as to any bio-control or
mechanical measures that have been proven effective contra white fly
(Homopera, Trialeurodes vaporariorum & perhaps Bemesia tabaci).
Unfortunately, beneficial organisms are rarely available except when
bred to order here (few to none are available on demand), which limits
the possibilities. Worse still, from what I'm told the problem seems to
be due to a viral infection being transmitted by this vector, so any
measure may be too late even if effective.

So it looks like there will be no real substitute for preventative
measures taken early on: Dust and ant control, breeding lacewing and
encarsia to placing yellow sticky traps and spraying w/ insecticidal
soap - all should help and tobacco* dust or tea is known to have done
some good, but I'm hoping something else has been discoved that I'm not
aware of.

* the crop is not for the organic market, but when asked (as happened
late yesterday when doing the weekly shopping at the local farmer's
market), I prefer to never reccomend anything that's going to wreck much
havoc with any naturally occuring controls that may be present.
