The population of insects in the world has decreased significantly due to the use of pesticides and other factors, with a "disastrous" effect on the planet, a study has been warned.
More than 40% of the insect species may resign the next time in recent years, according to "The entomofauna declining world: A report on its drivers" published in the Conservation magazine Biological
Insect biomass decreases by 2.5% per annum, a rate that shows widespread conception within Now, the report received.
In addition to the 40% at risk of death, a third of the species are at risk – which can drop the ecosystem loss of the planet with a catastrophic impact on world-wide life .
The report, co-operated by scientists from the universities of Sydney and Queensland and the Chinese Agricultural Sciences Academy, looked at the many current reports on insect decline published over the last decade and examined the reasons behind the numbers falling to produce the scary global picture.
A genitive editing could end mosquitoes, but it's a good idea?
Lead author Francisco Sanchez-Bayo, of the School of Life and Environmental Sciences at the University of Sydney, asked the first world-class study of the question.
Although the decline in biodiversity of vertebrate animals has been the focus of the focus, this study emphasized the importance of insect life on interconnected ecosystems and the food chain. The bugs make up about 70% of all animal species.
The consequences of insect descent would be "disastrous as the smallest say," according to the report, as insects were "the structural and functional base of most of the world's ecosystems since the rise. … almost 400 million years ago. "
The main cause of the decline was" habitat loss and serious intensity of agriculture and urbanization, "pollution, especially from pesticides and fertilizers, as well as biological factors, such as" pathogens and introduced species "and climate change.
Although a large number of specialized insects, ecological niche filling, and general insects had a large decrease, a small group of insects were adaptable looking at increasing the number of numbers – but not near the capture of the decline, received the report.
Small world-run creatures
Don Sands, entomologist and Org Commonwealth Science and Industry Research retired "totally" stated that the "basic" effects of serious insect loss were.
"If we do not have insects as modifiers of other pest populations, we have insect communities that emerge and turn bars and make them hard 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.

Descriptions of the new insects are not reported: researchers have warned the phenomenon and their influence over the years.
Last year, one study found that flight populations in German natural reserves dropped more than 75% for a 27 year study, which means that death is happening even beyond areas of activity humans on them.
"These are not agricultural areas, these are the places to preserve biodiversity, but we still see that the insects are flowing out of our hands," said co-author of that report, Caspar Hallman.
Birds eating birds
Species that are dependent on insects as their source of food – and higher predators up the food chain that these species eat – these reductions are likely to occur, according to scientists . The colonization of both crops and wild plants as well as nutrient cycling in the soil.
Indeed, "ecosystem services provided by wild insects are estimated at $ 57 billion annually in the United States," according to earlier study.
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 deterioration of insects is an immediate risk of insect bird loss, and the risk of eating more birds from eating insects 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 Required
The authors of the report requested radical and immediate action.
"As insects are the most abundant and (species-animal) group of animals and critical services within ecosystems, such events can not be ignored and decisive action should be taken in a way to announce the catastrophic disaster of the ecosystems of nature, "they wrote.
They recommended reforming existing agricultural methods, "in particular, a serious reduction in the use of pesticide and the replacement of ecological-based ecosystems".
"The conclusion is clear: if We will change our ways of eating food production, insects as a whole will go down the corridor of the eradication in a couple of years, "they finished.
