Summer is here!
All kinds of bugs have also begun to "actively operate"
life
A lot of people come across bugs
The first reaction is always "take a shot"
Recently, though, someone
Because of this knee-jerk behavior
Hurt!

Recently, a lady from Yixing City, Jiangsu Province, after walking home outdoors, suddenly felt that there were insects crawling on her face, she instinctively patted it with her hand, but suddenly felt a hot pain in her face. When I looked in the mirror, I had a few blisters on my face, as if I had been scalded by boiling water!
Subsequently, she hurried with a tissue
Wrapped in a worm that was shot to death
Go to the hospital
Doctors combined her symptoms
The diagnosis is:
Poisonous insect stings, chemical burns
and the worm that caused the lady to be injured
Commonly known as "fart bug"
Scientific name: Qibu Jia
The "poison" released by this insect
It's not just your average hot
Rather, it is a "poisonous fart" close to 100°C......
I can release "a fart that is so hot that it smokes"
How do these beetles do it?
Let's take a look

A beetle that can fart
Among the many insects with "chemical weapons", the Qibu Armor stands out from the crowd.

The gas beetle generally refers to a large group of insects in the family Foot Caratilaceae, such as the genus Gasstep and the genus Fart. They have six long legs, move quickly, and often have distinct markings on their elytra. I like to hide in damp places such as bricks and tiles, grass, etc., and eat some small insects such as caterpillars, snails, and slugs.

If you hold it down on its back, it will squirt a burst of smoky liquid from the end of its abdomen, and if you are lucky enough to grab it with your bare hands, you will soon feel a strong burning sensation on your hands, and the skin that has been sprayed will also turn yellow, and it will take several days to recover.

Moreover, the dose of the qibu armor spray is quite large, and after being sprayed once, it may be sprayed a second or third time if you press it, spraying yourself into a fairy mist.

Such a hot "fart"
How was it released?

In fact, the "poisonous fart" of the 100°C gas step armor is not casually released, it belongs to the chemical defense behavior of the gas step armor. Secondly, to be precise, the gas step armor is not called a fart, but a white smoke-like liquid.
In the 1950s, a team of German chemists first determined the main components of the gas walking armor. Scientists have experimentally measured that the main components of the liquid "fart" of the gas step nail are benzoquinone and methylbenzoquinone. Benoquinone is a toxic yellow crystal, which is easily volatile and sublimated, and has strong irritation to the eyes, skin, and mucous membranes.
How is benzoquinone synthesized?
The green part is the gas step nail storage chamber, and the red part is the reaction chamber
The "body factory" of the Qibu Armor is the liquid storage chamber and reaction chamber located in the posterior part of the abdomen.
The glandular cells in the reservoir can produce hydroquinone and hydrogen peroxide, and when these two compounds are squeezed into the reaction chamber, a violent reaction occurs - catalase catalizes the decomposition of hydrogen peroxide into oxygen and water, and the oxygen oxidizes hydroquinone to benzoquinone under the catalase catalytic catalyze, and finally is ejected out of the body along with the remaining oxygen!
The Air Infantry Armor can flexibly adjust its position for defensive attacks
The picture shows its farts in front of and on the left and right
Is there any experimental data for that burning experience?
Really! In a 1969 paper in the journal Science, scientists determined that the air nail spray was close to 100 °C, and each milligram of spray contained 0.22 calories!
But won't such a fart burn itself? It really won't, the thick stratum corneum of the nail gluteal gland system in the air walking nail bubble ejection can help it avoid self-injury!

Do you want to shout "increase knowledge!" ”
Finally, here's this tip

Please accept the summer insect control guide
In addition to the qibu beetle in summer, there are many mosquitoes active, so close the screen doors and windows at home, wear long clothes and long sleeves for outdoor activities, and spray mosquito repellent on the body before going out.
If there are insects you don't know that stop on your body, use a fan, clothing, etc. to drive them away, and don't shoot them directly on your bare skin!
Remember!
Meet small bugs in the summer
Don't take it easy
Slap on bare skin~
