If the pupae/larvae get infected in the first few days of their life, and then drop to the ground for a few says before emerging as infected adults, maybe you should kill the soil under the infected plant you pulled. Pour some bleach on it or something.
If you read in the post above:

Only larvae pick up the virus and only adults transmit it. Adults can transmit the virus within 30 minutes of feeding. If larval stages can be controlled, virus transmission can be prevented, even if adult thrips are present

In other words, the pupae emerging from under infected plants are guaranteed to be infected. Kill em while they are in the ground.
It may be a good idea to try to kill them in the ground under any infected plant, even before you pull the plant.
Any suggestions as to what might be the best treatment to do that? Bleach? Maybe some bleach covered with plastic sheet so the chlorine gas will get them.
