I do use the yellow sticky whitefly traps and spray occasionally with Neem or spinosad to control whitefish and leaf miners. I guess perhaps not enough.
The only plant right now showing no signs is a Pink Berkeley Tie Dye.
I think the (also-diseased) citrus trees in my yard contribute to the whitefly problem. I'm probably having them removed soon since they are no longer producing edible fruit.

The whiteflies that affect tomato plants are the silverleaf whitefly, called that because it turns brassica leafs silvery, they get a silver sheen. There are more than 30 species of whitefly in florida.
I put my yellow sticky traps out every 5 feet, and keep them a little below the top of the tomato plants.
