Insect that fights Japanese knotweed to be released,<a href="http://www.buyblade.com">Japanese Swords</a> Insect that fights Japanese knotweed to be released A tiny Japanese insect that could help the fight artificial pumpkinsagainst an aggressive superweed has been given the go-ahead for a trial release in England.

Since Japanese knotweed was introduced to the UK #xit has rapidly spread, and the plant currently costs over ￡150m a year to control and clear.

But scientists say a natural predator in the weed's native home of Japan could also help to control it here.

The insect will initially be released in a handful of sites this spring.

This is the first time that biocontrol - the use of a "natural predator" to control a pestartificial pumpkins - 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."

Alien invaders

Japanese knotweed was introduced to the UK by the Victorians as an ornamental plant, but it soon escaped from gardens and began its rampant spread throughout the UK.

It grows incredibly quickly - more than one metre a month #x- and rapidly swamps any other vegetation in its path.

It is so hardy thatartificial pumpkins it can burst through tarmac and concrete, causing costly damage to pavements, roads and buildings. 相关的主题文章：
