Terrifying parasitic viespa in Amazon turns spiders into zombie dials

Scientists exploring Ecuadorian Amazon have discovered a new species of parasitic wasp, which turns victims into zombies.

As the researchers say, it is a form of "hardcore" embezzlement, these wasps make it the social spiders to turn their back on their own colony before rotating a cocoon for the larvae to eat it From behind.

The terrible attacks are noted in most other cases known to bewolf parasitism, being unusual in that they do not target a solitary spider species, as is usually the case.

"Wasps that manipulate the behavior of spiders have been noticed, but not at such a high level," said Philippe Fernandez-Fournier, lead author of the study and former student at the UBC Department of Zoology.

"Not only does this vagrant target a social spider species, but it makes her leave the colonies, which rarely does."

The parasitic wasp comes from the genus Zatypota and targets a spider called Anelosimus eximius – a unique social species of the spider, known to live in large colonies and cooperates with others to capture the prey and raise the young.

During the research, the team noticed that some were infected with a parasitic larva and could be seen wandering from the colonies to break closed networks.

"It was very strange, because I do not normally do that, so I started writing," the researcher said.

After bringing some of the so-called "cocoons" back to the lab to investigate, the researcher discovered that there were wasps inside.

"These wasps are very elegant and are graceful," said Samantha Straus, co-author of the study and PhD student in the zoology department of OBC.

– But then I do the most brutal things.

According to the researchers, adult female vipera first introduces an egg on the spider's abdomen.

Eventually, the larva traces and attaches itself to the body of the spider, nourishing it as it grows.

In a zombie state, the spider leaves its colony and creates a cocoon for the larvae. Then he is waiting to be killed and consumed.

The larvae appears nine to eleven days later.

WHAT IS PARASITOID?

Parasitoids are insect parasitic larvae that eat their host – usually another insect – from the inside out.

They often use a sharp instrument, known as the ovipositor, for storing eggs under the skin or the exoskeleton of unsuspected hosts.

After a short period of gestation, the larvae detach themselves and begin to eat their hosts, usually reaching maturity when the host dies.

Parasitoid species are, for the most part, bees, wasps, and ant, though some fly species also use terrible technique.

The parasitoid biology has inspired several science fiction writers and writers to create parasitoid aliens that kill human hosts, including Xenomorph Infamous in Ridley Scott's 1979 "Alien" movie.

"This change in behavior is so hard," Straus said.

"Viespa completely kills the spider's behavior and brain and makes her do something she would never do to leave her nest and rotate in a completely different structure. It's very dangerous for these tiny spiders.

Researchers have not yet realized how the spiders make spiders to abandon their colonies, although I suspect that the use of hormones, which might deceive them into believing they are at a different stage in life, may be to blame.

"We think the snakes are targeting these social spiders because they offer a broad and stable colony of hosts and a source of food," Straus said.

"We also found that the higher the spider's colony, the more likely it is for these wasps to target it."
