A combination of orthene and a fungicide available through ACE Hardware. I have found this to be an effective systemic insecticide that does no harm to my plants. It is marketed in two forms: a larger container of mix it yourself (~$18.00) and in smaller spray cans (~$10.00).

I agree! This is a great product. As always, I try to remind growers to use this and other sprays in the cool part of the day, morning or evening, (best when not in direct sun) to prevent burning tender leaves. It is a systemic spray and not listed for edible crops, so no nectar licking after application
Nope, this stuff doesn't work for whitefly in my experience. Try the Bayer insecticide with Imidicloprid which doesn't seem to harm Neps. You might also try the granules, but I have no experience with them.

I use a mixture of Merit and Delta-Guard. Merit is a systemic insecticide which kills sucking pests and I also use the Delta-Guard (A synthetic pyrethroid) to kill the larval and egg-emerging nymphs. I wish I had more time to do a thorough spraying so that I can spray everything at once and then this will help curb their breeding batches.
I have also used Avid to some degree for this pest.
I have used Ced-o-flora on the non-hirsute Neps. species. I have only used it on about 8 different species so far, with no untoward effects, and it has eliminated the scale and thrips on those plants (so far - just a few months). I bought it from Logees.com. I have copied the following from their catalogue description,
"Ced-O-Flora Plant Spray The first choice for the container gardener when confronted with infestation of scale. A long time friend, we’ve used this product for decades and consider it an absolute must for your arsenal. Excellent for use in shiny leaved plants such as Citrus and Bay. One application does the trick. Also it will control most other insects. However, plant damage can be observed on soft, hairy leaved species, so be sure to test a few leaves before spraying on the whole plant. " (www.logees.com, Plant Care Products)
