The red stairs are moving to a new location, invasive methods are like a cycle of ecological disaster – driving out natural insects and small animals and causing serious harm to homeowners. But there is good news for scientists at the University of Texas at Austin, because they have shown that they are using a natural teller to cut off a population of crazy stairs. They report their work this week in the journal Proceedings of the National Academy of Sciences.

“I think there’s a lot of power in protecting vulnerable habitats with hazardous conditions or areas of high -maintenance property,” said Edward LeBrun, a research scientist with Texas Invasive Species. Research Program at Brackenridge Field Laboratory and lead author of the research. .

In some parts of Texas, buildings are filled with stairs that contain broken air vents, AC components, water waste and other electrical appliances, causing shortages and other accidents. . Indigenous people of South America, red -bellied red flags, have been ringing alarm bells as they have spread to southern America over the past 20 years. The idea for using a fungal pathogen came from looking at the wild number of insane nets that go sick and fall apart without human intervention.

“This idea isn’t going to miss the crazy steps,” LeBrun said. “It’s impossible to predict how long a lightning strike and a pathogen will affect an insane person.

Other research authors include Rob Plowes and Lawrence Gilbert at Brackenridge Field Laboratory, and Melissa Jones at the Texas Parks and Wildlife Department.

About eight years ago, Plowes and LeBrun were studying the insane scales collected in Florida when they discovered that their stomachs were swollen with fat. When they look inside their bodies, they find spores from a microsporidian, a group of fungal pathogens – a new species in science. Microsporidian pathogens normally attach to the fat cells of an insect and turn them into spore structures.

It is not clear where the pathogen came from, whether it was native to the insects in South America or from another insect, but LeBrun and his colleagues began to search for the pathogen in Kind of crazy in places in Texas. Looking at 15 local people over eight years, the team found that each population denied exposure to the pathogen – and 62% of that population was completely extinct.

“You don’t expect a pathogen to lead to the extinction of the population,” he said. “The disease population is going in boom-and-bust cycles as the disease rate increases and decreases.”

LeBrun thinks the colonies may have collapsed because the pathogen has shortened the lifespan of intoxicants, making it harder for the population to survive the winter.

The reason is it’s just a crazy problem. Unlike other microsporidia that bind to the stems, the pathogen is known to leave the native and other species without harm, as if it were an excellent biocontrol agent.

The company introduced the pathogen in this way after LeBrun received a phone call from Estero Llano Grande State Park in Weslaco, Texas, in 2016. The tobacco has lost its insects, poisonous tail lizards, worms. snakes, lizards and birds on crazy stairs. The rabbit babies in their nests were blinded by the bitter gourd.

“They had an insane ant disease, and it was apocalyptic, streams of stairs going up and down every tree,” LeBrun said. “I’m not ready to start this as an experimental process, but it’s like, OK, just give it a go.”

Using insane cells they collected from other cells infected with the microsporidian pathogen, the researchers inserted the infected cells into nest boxes near the insane ant nest sites in the state park. . They placed hot dogs around the door rooms in order to pull out the local poisons and combine the two numbers. The experiment worked well. In the first year, the disease spread to the insane ant population in Estero. Within two years, their numbers had dwindled. Now, they are gone, and the natives are returning to the land. Researchers have identified a second insane ant population at another site in the Convict Hill area of ​​Austin.

The researchers plan to test their new biocontrol approach to this well in other parts of Texas that are infested with crazy monsters.
