Found carved natural semen of human blood-sucking mosquitoes

There are now 2 jumping spiders that specialize in hunting mosquitoes and one of them is especially "addicted" to mosquitoes that suck in full of human blood. Species carved for this mosquito may be a natural ally of humans in the fight against malaria.

Detection of natural etching of Anopheles mosquitoes

Many species of spiders are recorded to eat mosquitoes, human beings that transmit malaria to humans. But, according to researchers at the University of Canterbury (New Zealand), only two of them can be identified as "mosquito killers" : Evarcha culicivora and Paracyrba wanlessi.

Researcher Fiona Cross said: "These two spiders are killer killers. They will ignore all other insects along the way as they pursue their goals - mosquitoes."

Often discovered on the walls of buildings in East Africa, the spider Evarcha culicivora is especially attracted to the Anopheles mosquitoes that are full of blood. Meanwhile, Anopheles mosquitoes are a mosquito that infects Plasmodium malaria parasites, causing up to half a million deaths each year, according to the latest estimates by the World Health Organization (WHO). .

Researchers found that both spider E. culicivora and Anopheles mosquitoes are naturally grown in Kenya and have the smell of people, especially the dirty, seductive smell. However, E. culicivora also likes to eat meat Anopheles mosquitoes - enemies of humans.

Although also like the taste of human blood, spider spider E. culicivora does not threaten us , because they lack the appendage of the mouth to pierce human skin and suck blood. In addition, thanks to complexly structured eyes, they can identify whether a mosquito is both "cup" full of blood, based on the tilt of the abdomen, to jump to catch prey.

" This is unique. No other animal attacks prey based on what the prey has eaten," Cross researcher said.

Meanwhile, Paracyrba wanlessi spiders of Malaysia are often found in hollow bamboo stings. They eat the larvae of mosquitoes wiggling in small puddles forming inside bamboo trees.

The team identified humans as being able to use "natural enemies " of mosquitoes such as these two spiders to control and eliminate these dangerous blood-sucking insects. However, they concede, this idea is difficult to implement because the public, including entomologists, is also frightened of spiders.
