Lords ChamberRead Full debate Read Hansard Text Read Debate Ministerial Extracts
Lord Henley
My Lords, if those tests are successful, obviously we would want to take it on, on advice from the appropriate scientists, to lead to greater control of Japanese knotweed. I have to say that it will take a considerable time before we know whether it will be effective; it is thought that it could be five to 10 years before we see any evidence of greater control.
Baroness Gardner of Parkes
Can the Minister tell us exactly what this mysteriously named thing is? Is it an insect, is it like the Hawaiian cane toad in Australia, or is it bacterial?
Lord Henley
My Lords, the psyllid known as Aphalara whatever it was, is a very small bug, of the order of two to three millimetres long. It is difficult to see with the naked eye, and a magnifying glass may be used better to see it. I have some pictures, which I could show to my noble friend after this Question if she wants to see whether she can identify that bug.
