Insects are progressing – we're wearing beetles and butterflies but we're getting cockroaches



"A nationwide population is" threatened, but only resilient species such as urban cockroaches have a trend that have significant implications for relying on animals, Australian-based researchers say.

Although two butterflies could be stimulated and even nutritionally small-scale beetles, there is a deterioration of common and resilient species, such as excessive nutrients that are inappropriate and at home in both forests and cities.

Although Australia insects are likely to have the same spiral at the same time in Europe and North America, since similar farm chemicals are being used, the information that is by local species being more difficult to consider the impact of decline, Francisco Sanchez-Bayo, an honorary association at the University of Sydney said.

species themselves, "said Sanchez-Bayo." We can not study long-term and can not do it across Australia ̵

1; it's too big. We do not have our human resources. "

Swallowtail Mhicleay, one of the butterflies found around Canberra.

It was estimated that only 30 percent of recognized Australian insect species. Scientists' job cuts, including government agencies, were more difficult to monitor known species populations, not to mention the new ones.

Sanchez-Bayo and Kris Wyckhuys report in April's biological conservation edition states that the third of all species of insects are threatened in the countries studied. The bit Insect total insect also decreased at a 2.5 percent worldwide rate, the review was found in 73 historical reports.

The habitat loss paper – for example the spread of cities and the intensification of farming – was identified as pesticides and other agricultural chemicals, the rise of pathogens and climate change as the main factors behind the reduction.

"The general public does not have important insects – they pay attention to them as a nuisance," said Sanchez-Bayo. "It's really – insects are going everywhere."

In fact, insects are crucial to polishing, recycling materials in soil and water. They also provide the main source of food for birds, wings, fish and many other vertebrate species that attract more scientific interest and public sympathy.

"If the source of food is growing, what is happening now, all of these animals will go to the illness," said Sanchez-Bayo. "They simply disappear because they do not have food."

& AN OTHER 99 PER CENT & # 39;

Richard Kingsford, director of the Center for Ecosystem Science at NSW University, often referred to as "the other 99 per cent centrifuges" because they make most of the world's biodiversity.

"They're a bit out of sight, in memory when we measure and monitor biodiversity focusing on the megafauna – birds, mammals, reptiles, frogs and fish – but environmental life is about," said Kingsford.

"They do many things for humanity that do not cost us anything. And they are crucial to the future of the planet," he said, putting the new paper available "the trend in the world reduces it biodiversity screening ".

Sanchez-Bayo said that many of the people could understand from day to day experiences that the insect numbers were on the skids.

He said driving in the bus of Australia used to fill insects with insects. In contrast, leaving a road trip from Sydney to Cooma in the Snowy Mountains scored "untouched".

& # 39; TOO MUCH PESTICIDES & # 39;

Although his papers with Wyckhuys were highly focused on research from North America and Europe, the number of insects associated with the use of higher pesticides in other places is likely to be, for example Africa and South America.

"The farmers are using too many pesticides," he said. "That's why farming practices in those countries are likely to be much more than the impact they have in European and North American countries."

Farmers must "go back in the way we've done things in the past", Sanchez-Bay Bayo, such as the introduction of hedgerows or other habitats to nurture different species – some of them would do non-chemical insects control.

Although climate change increases the range for certain insects, the impact on other regions may be negative, especially in the tropics.

"We know that insects in smaller tropical areas are less at changing temperatures," he said.
