I was also reading about thrips recently: this article from Florida is very informative about thrips and TSWV, and results of different treatments in the field:

I have been suffering a thrips infestation on pepper plants which are still in the house.
I don't see any signs of TSWV afaict, but I am not going to put any peppers in the greenhouse with tomatoes just in case. The thrips damage alone is nasty enough. Really no way to kill the bugs once they are in the plant tissue, only cull and prune.
Has anyone used diatomaceous earth on the soil surface to stop new ones from emerging? Does this help?
