More than 40% of the insect species could be expired in the coming years, according to the "Global fall on the entomofauna: Report on the driver report", published in the magazine Biological Conservation.
Biomass reduction is a 2.5% improvement per year, a rate that represents widespread conception within one hundred years, the report received.
In addition to the 40% at risk of death, one-third of the species are at risk – numbers that can cause the ecosystem to fall in the planet with a catastrophic impact on life on Earth .
The report, consulted by scientists from the universities of Sydney and Queensland and the Academy of Agricultural Sciences of China, reported on the many current reports of insect deterioration published over the past thirty years, and examined the reasons which is behind the numbers that were falling to produce the scary global picture.
Lead author Francisco Sanchez-Bayo, of the School of Life and Environmental Sciences at the University of Sydney, asked the first global study of the issue.
Although the focus on the reduction in biodiversity of vertebrate animals, this study emphasized the importance of insect life on interconnected ecosystems and the food chain. 1
The consequences of "disastrous" insect effluent, according to the report, would mean that insects were "the structural and functional base of many of the world's ecosystems since they will rise … almost 400 million years ago. "
The main causes of the decline were" habitat loss and intense conversion to agriculture and urbanization, "pollution, especially from pesticides and fertilizers, as well as biological factors, such as" pathogens and species introduced "and climate change.
Although a large number of specialized insects, ecological nerve filling, and general insects decreasing, a shorter number of adaptable insects increased – but they are not near enough to capture the decline, the report.
Small creatures run by the world
Don Sands, scientist and scientist of the Commonwealth Industry Research Organization announced "totally" that the "fundamental" effects were loss of serious insects.
"If we do not have insects like other pest populations, we have insect populations that hit and bark bars and make it difficult to grow," he said.
He said that the ecosystem at this level is "to be balanced. That is the bottom layer and if we do not face it, it can have an impact on our entire life .
"(Insects) run the small creatures around the world," he said.
Reports of insects that have no new deterioration: researchers have warned the phenomenon and their influence over the years.  Last year, one study found that flight insect populations in German natural reserves increased by over 75% during a 27 year study, which means that death dies before the previous night areas affected by human activity.
"These are not agricultural areas, these are the places in which biodiversity is preserved, but we still see the insects that spread out of our hands," c said author of that report, Caspar Hallman.
Birds eating bird
Species that are dependent on insects as their source of food – and predators higher up the food chain Eat those species – depending on those cuts, according to the scientists. The poles of both crops and wild plants, as well as nutrient cycling in the soil.
Approximately 80% of the wild insect plants use for pollination and 60% of the birds depend on insects as a source of food, according to the study. Sands said that the insect deterioration of insect bird loss is an immediate risk, and more dietary eating birds would eat to eat each other.
Indigenous in Australia, "birds running out of insect food are turning to each other," he said, adding that this is probably a global phenomenon.
Radical action needed
The authors of the report requested radical and immediate action.
"As insects are the group of most abundant animals and (diverse species) and provide critical services within ecosystems, such events can not be ignored and a decisive action to disaster disasters of the ecosystem of nature, "they wrote.
They advocated the reform of existing agricultural methods, "in particular a serious reduction in the use of pesticides and the replacement of ecosystem-based, more sustainable practices".
"The conclusion is clear: if we do not change our ways of producing food, insects will be totally going down the corridor of the disappearance in a couple of years."
