There are three "whitefly" entries in the Library of Organic Information:

Quote:
Whiteflies are one of the harder to control insect pests, but as usual the organic approach works better than the toxic chemical approach. These pure white flies primarily attack weak plants that don't necessarily look weak. High nitrogen synthetic fertilizers are one of the main causes of this pest. Whiteflies are the most troublesome in phosphorus deficient soils. Soft rock phosphate and well-made manure-based compost are these best tools for providing available phosphorus and preventing this pest.
To rid existing infestations, spray plants with garlic tea, garlic-pepper tea, or the fire ant control mixture but the secret weapon is seaweed. Add it to any of the organic sprays and the control will be much more satisfactory. Stimulating beneficial biological activity with organic fertilizer, Garrett Juice and other natural soil amendments will help greatly to control this pretty but annoying pest.
When using a total organic program, you and your plants will get to enjoy a greater population of helpful insects and microbes that are the long term control of this and other pests. In your greenhouse the yellow sticky traps are good to use as a monitoring device and will offer some control.
I hope this helps.
