Apparently scientists want to release lice also called psyllids to counter the Japanese Knotweed problem.
Now like me your first reaction will be to wonder what other problems this will cause.
Scientists at Commonwealth Agricultural Bureaux International (Cabi) believe they will not cause any environmental damage. Other experts urged caution, saying introducing them might have unintended consequences, such as feeding on British relatives of the knotweed.
But Dick Shaw, principal investigator at Cabi, said "Japanese knotweed has been described as having the biodiversity value of concrete – it just smothers the ground in a mass," ... "We hope the psyllid will get the plant under control."
Hope? Hope!!
A few counter arguments Craig Macadam of Buglife, "Do they only eat Japanese knotweed or do they eat domestic plants? We do have native knotweeds in this country. It is a question of whether these things would feed on those, too."
Chris Rostron, of The Wildlife Trusts, "Invasive species such as Japanese knotweed pose a serious threat to Britain's biodiversity, particularly wetland habitats. But introducing any non-native species for biological control carries risks and must be thoroughly researched."
