Fleadom! Holland releases 5,000 fleas to solve knotweed problem:
Dutch researchers have released thousands of Japanese leaf fleas in hopes of getting a harmful and invasive plant species under control.
Japanese knotweed, also known as Asian knotweed, were first introduced to the Netherlands in the 19th century as an ornamental plant, but the species is now notoriously invasive. Its roots can damage concrete pavements and foundations and it is so proliferous that it chokes out local flora.
For the first time, the Dutch government issued an exemption on a nationwide ban on introducing an alien species to the Netherlands in order to combat the plant. 5,000 of the insects will be released on three field locations initially, to determine if they will survive the winter and establish themselves through the new year.
The leaf flea, also known as the Japanese knotweed psyllid (Aphalara itadori), is a natural predator of knotweed. It feeds on young shoots of knotweed plants and can slow down or even stop its growth by sucking on the nutritious sap of the plant.
Researchers from the Institute of Biology in Leiden, where Japanese knotweed was first brought into the Netherlands, started field experiments this week to use the psyllid as a "weapon" against the incendiary plant.
[...] As to whether the psyllid could turn the tables and cause widespread damage to other plants, Ms Lommen said: "There are very reliable methods to determine this. For example, extensive risk analyses have been performed for plant species in North America, England and Northwestern Europe.
[...] Japanese Knotweed is is classified as an invasive and destructive species in several countries

If the fleas eat all the knotweed, will they then conveniently die, or will they find something else in Holland to eat?

Indeed. I hope they at least tested them on native plants in a controlled environment to see if there's something native they'll find more appealing than knotweed.
After all, there's a long history of intentionally introducing new invasive species to eliminate an existing one, only to make the problem worse.

I read in the Dutch news they already tested more than a hundred plant species if they would be targetted by these fleas, all were found to be negative. (source: https://nos.nl/artikel/2353353-duizenden-japanse-bladvlooien-in-natuur-om-japanse-duizendknoop-te-bestrijden.html) [nos.nl]

I wonder why so many suckers believe this sort of stuff can work.
The fleas certainly have NOT driven the japanese knotweed to extinction where both came from... The weed certainly isn't rare in Japan.
It might work if the fleas can survive on other stuff and reproduce to huge amounts but will ALWAYS prefer knotweed when given the choice.
So their population will go up, and wherever knotweed appears, it gets wiped out.
BUT that means the fleas could end up being a bigger problem since they're eating other stuff...
It's just like a disease wiping us humans out. If we're their sole host, that's unlikely to happen - the disease and/or humans will tend to evolve to avoid extinction. But if the reservoir species of the disease is larger in population than the target species then yes the target species might go extinct. So for example a disease that kills both humans and chimps, could wipe out the chimps if humans keep spreading it to the chimps.
