Fear No Weevil: Taking on the World’s Worst Weed
Ya, I'm waiting for the weevils to say, "fuck this Salvinia shit, this (insert cash crop here) is AWESOME!"
So, to manage an invasive species, they imported a different invasive species?
Fear No Weevil: Taking on the World’s Worst Weed
Nutria don't die off every winter, so the weevils are likely to be less of a problem. There was actually a small scale trial before they built the weevil greenhouses, which didn't uncover any major issues with them.
See https://features.texasmonthly.com/editorial/creature-green-lagoon/ for many more details including the lack of frost tolerance:
I hope this goes better than the introduction of nutria, which Texas did to combat other invasive water weeds. They are now a major problem, causing massive erosion problems and displacing naive species. It makes me wonder what problems these weevils are going to cause in 10 years....how many native plants will they eat to extinction?
