The first sanctioned release of an alien species and it's in Swansea!

A trial release of a Japanese Psyllid Aphalara itadori (a hemipteroid sap-sucking insect) has been sanctioned to take place in Swansea in July. The following two newspaper articles are all I I know about at present:



Personally I have reservations about how effective a control agent it will actually be. As far as I am aware it will not be used to transmit a specific pathogen, so surely it's just going to live on the plant, rather than eradicate it! From the little I know about this project, it currently makes no sense to me, but I'll be happy to be put on the right track.

Perhaps the newly arroved Harlequin Ladybirds will control these control agents before they have a chance to control the Knotweed! Ecology is never simple and I suspect this trial will throw up a few surprises...
