U of F with an experiment in my yard
Because I'm in contact with the county agent, I've been chosen as an experiment and hopefully a long term solution to the white fly problem. About 6 weeks ago there was a bunch of people in my yard. The county agent, a Phd from U of F, And another phd from State of Fl, dept. of Ag. and his assistant.
They brought a "banker" plant. A potted bird of paradise to be infected with white fly. Now, 6 weeks later they brought predators. A tiny wasp that lays eggs in the fly and kills it. The predators are in a mesh bag, placed on the plant, that allows the wasps to get out but not the white flies emerging from eggs in the mesh bag. That way the wasps can leave and establish more colonies.
This predator is here already in the environment but far too few. This is an attempt to bolster the wasp population. They tell me that their process will not clean a heavily infested yard but would defend a mostly clean yard. So now I'm waiting for the wasps to emerge. Supposed to be in 3 weeks.
This is a very serious problem that started in Miami. The fly was a hitchhiker on a ship that entered the port. It has spread as far north as Melbourne Beach. We have had heavy infestations in my neighborhood.
I hope this works. If it does it will take 6 to 12 months. Fingers crossed.
