Infected & Zombie Spiders & # 39; incubation cameras for their parasitic supplements

Parasites that control their behavior on their owners are a well-documented natural phenomenon, but the discovery of previously unknown relationships between parasite barley and social parasites is particularly damaging.

Stealing the brain of unwanted hosts is something that some organisms usually do for reproductive purposes. Certain examples are the fungus that controls the behavior of the carpenter's idols, homogeneous cell parasites that smell of copper milk that do not affect rodents, and worms that cause infected fish to perform dance.

Another parasitic relationship found by scientists from the British Columbia University can now be added to this list, and this is one of the worst scenes we have ever seen, with its complexity and weaknesses. In a new study published in ecological entomology, the leading author, Philip Fernandez-Fornever Whatsapp Parasitic cows are socially exploited and misused Anelosimus eximius The spider first uses it as a machine, and then forces it to create an incubation chamber. Oh, then a spider eat.

Fernández-Fournier was found to have accidentally found in Ecuador's Amazon, with various parasites A. eximius. These arachnids are called social spiders, because they live in large colonies, work together to get rid of corruption, share their parental duties, and rarely go beyond the limits of their communal, crooked nest.

These spiders are harsh in behavior, so Fernandez-Forné drew attention to some of these spiders attacking one or two feet in the colony with a parasitic larva. This competition was rare and rare, but the UBC scientist saw that the packers began to circulate the thin silk and leaves.

"It's so beautiful, because they do not work as usual, so I've started the remarks," said Fernandez-Furnire.

Interestingly, he recaptured the cocoon lattices into the laboratory. When he opened it, he saw his stomach – a developing barley in it. Fernandez-Forneri and his team have identified and analyzed the two unexpected aspects of the relationship.

How it works: an adult woman Whatsapp Cucumber Egg Egg Anelosimus eximius spider After larvae, it is added to the spider and fed to its blood. The larva grows gradually, and it begins a large part of the spine body. In the end, the spider enters into a state of "zombie", where he can not behave spontaneously. Under the effect of the larva, the spider abandons its colonies and sets the task of creating a cocoon line. After the compulsory construction work is finished, the larvae kill the larva before the pawns move, and let the owner complete the job. The crushed larva enters the web cocoon that it uses as the incubator for the next stage of the fetus. After nine to nine days, the cocoon is full of bitterness. The cycle will, unfortunately, restart for the next eight legs.

The strategy, according to researchers, is that the parasitoids are pre-emptied only in the usual germs.

"But this behavior is so intriguing," said Samantha Strauss, co-author of the study. "Throws the woodsman's behavior and brain completely and never does anything that he does not do, for example, leaving his nest and making a completely different structure. This is very dangerous for small spiders. "

Strauss adds: "We think these yard cows are against this social spider, because it gives a large, stable host colony and food. We also found that the spider colony was wider, which aerosols could accomplish.

Researchers have discovered how the hypnotic spell of the infected spinal cord detects the spinal cord's introduction of a brain-changing hormone. This hormone or puppy may stimulate the thinking of another life, or it will act as a spinal cord escape from the colony. But this is just a forecast.

Fernandez-Fournier and Straus now want to return to Ecuador's forest to find out more about these attacks and their owners. In particular, they know that they are targeted at the same spider colony several times, and if that is the case, this is the advantage of behavior.
