Multiple-choice oviposition studies using 87 species/varieties of test plants showed that only 1.52% of 146,885 eggs were laid outside what we call the invasive knotweed group. Dr Shaw said: "On the localised sites, I would expect to see damaged knotweed this season. Common names. In March 2010, the decision was made to release into the wild a Japanese insect into the UK in a bid to help control the outbreak of the weed.

These will be isolated and, in addition to as having the superweed present, will also have UK species that are closely related to Japanese knotweed planted there to check that the psyllid only targets the invasive species. "Insecticide and herbicide treatment will be on standby for rapid response.". The insects will initially be released on a handful of sites. The psyllid passed a stringent Pest Risk Analysis in the UK and was released there in 2010 and its populations are currently being monitored (Djeddour & Shaw, 2010).

It was the first biological control of a weed allowed by the European Union. Laboratory tests suggest the leaf fleas – Japanese knotweed psyllids, or Aphalara itadori – can kill young shoots and potentially stop the plant growing by sucking up its sap. This is the first time that biocontrol - the use of a "natural predator" to control a pest - has been used in the EU to fight a weed.

Wildlife Minister Huw Irranca-Davies said: "These tiny insects, which naturally prey on Japanese Knotweed, will help free local authorities and industry from the huge cost of treating and killing this devastating plant.". Controlled release trials began in South Wales in 2016. They looked at the superweed's natural predators - nearly 200 species of plant-eating insects and about 40 species of fungi - with the aim of finding one with an appetite for Japanese knotweed and little else. After testing their candidates on 90 different UK plant species, including plants closely related to Japanese knotweed such as bindweeds and important crops and ornamental species, they discovered a psyllid called Aphalara itadori was the best control agent.
