the UK imports INSECTS TO ADDRESS INVASIVE PLANT.
An ecosystem has a particular balance, when the latter introduce non-native species can cause serious problems. For the first time in the history of the United Kingdom, an alien species (which means a species not native to the place!) Will be vacated in attempt to combat the growth of another species, also brought in a totally different environment from its natural environment.
Millions of insects ( Fallopia japonica,
an invasive plant species imported for the first time in the Victorian era, which has since has become a serious threat to the entire ecosystem of the united kingdom. All alien species are considered "invasive", once they become difficult to control
... 
Studies " this plant can grow through concrete and asphalt, causing damage to buildings and walls, weakening the defenses of the levees, and stifling the growth of other plants . "In short, a real emergency too expensive when you consider that the UK spends 2.4 billion dollars in the fight against this plant. What's more, the
Fallopia japonica
no natural predators in the United Kingdom but here found the solution (hopefully) the bug Aphalara Itadori
is the natural enemy of this plant, because in Japan, it helps to keep under control the growth of this plant. In fact, this insect shows a certain preference in the eating of this plant. And according to tests conducted by the Center for Agriculture and non-profit Biosciences International (CABI), the psyllid will not eat any other type of native plant. (Even if it is, in turn, eaten by local predators.)
The problem seems also to other nations because the Fallopia japonica is widespread throughout North America, and the United States Department of Agriculture classifies as invasive species. According to the Plant Conservation Alliance, which provides some resources how to kill weeds, "The
Fallopia iaponica spreads rapidly and forms a dense undergrowth that excludes the native vegetation and greatly alter the natural ecosystem. It is a serious threat to coastal areas, can survive severe floods and is able to rapidly colonize various environments. Once settled in one place, the populations are extremely persistent .
Obviously, the introduction of an alien species to counter another sometimes has unintended consequences, just think what has happened in Australia with the toads. But
CABI stresses that the introduction of cane toads in Australia in 1935 to control beetles parasites was made against the advice of scientists, giving adverse results. Meanwhile, British government sources report that this is the best way to rid the country of Fallopia japonica: " This project is not only innovative, but it offers real hope that we can redress the balance."
An insect similar to 'aphalara itadori was released in Florida, a few years ago to tackle (
Melaleuca quinquenervia), an invasive tree originating from Australia', although the results so far are not yet conclusive.
