Why are you so calm, foreigner?
To tell the truth, this is a great discovery. It not only found a new mosquito, but also found a new feeding type of mosquitoes, which may even be a new feeding type in the animal kingdom ... Because most of the animals known at present, whether they are parasitic on animal surfaces or occasionally fly over to take a bite, are rare and even possible, at least I really haven't found it yet ... However, I was abroad in the evening of May 17. I used the search engine to search for keywords such as smoking/smoking, fat, mosquitoes, South Africa, etc. I found that some foreigners had discussed what would happen if mosquitoes ate fat, but I didn't find any relevant news ... Are you too quiet, foreigners?
This feeling is a little wrong ... but I'm not sure. In case I don't find it, if someone really publishes such a paper, I won't be slapped. Please look for it again. ...
However, there is something suspicious about this report, that is, once a mosquito bites a cow or horse, it will not pick up the bag, but sink a piece because the fat under the skin is sucked away. The problem is, according to this logic, the blood sucked by ordinary mosquitoes, even if it is liquid, can be replenished by flowing, and it will not sink, at least it will not protrude. In fact, bulging is an inflammatory reaction caused by mosquito bites, and what mosquitoes take away is far less than the scope of inflammatory reaction. Does mosquito's mouth sucking fat not cause inflammatory reaction?
Mozzie, how are you going to get fat?
If such a mosquito really exists, how does it absorb fat?
Mosquitoes have a special mouth, which is called stinging mouthparts in insects, or mouthparts that pierce the skin to absorb juice. Even if mosquitoes don't suck blood, they don't use other mouthparts. They suck nectar and other foods. If the newly discovered mosquito is indeed a mosquito, it should also be a mouthpiece, and the description of the report seems to confirm this, using the word "sucking".
Mosquito's mouthparts are very precise instruments. When sucking blood, they will pierce the surface of the skin, and then the needle-like structure around the mouthparts will support the crack. The main body of the mouthpart will scratch the capillaries of the skin, let the blood flow out, form a "blood pool", and then suck it away like a drink ... At this time, the mosquito's mouthpart uses two tubes, one for sucking blood and the other for spitting saliva containing anticoagulant. According to the research of French scientist Valerie Choumet and others (20 13), this greedy mosquito can deflate the damaged capillaries, and they will also look for new blood vessels to suck.
However, the blood-sucking activity of mosquitoes is limited below the epidermis, and our skin is divided into epidermis, dermis and subcutaneous tissue. The epidermis is very thin, as long as it reaches the dermis, blood vessels can be found, so it is not difficult for mosquitoes. But if you want to suck fat, you have to go through the dermis above 1mm or even a few millimeters and get it from subcutaneous tissue. This is definitely a challenge for their slender mouths. At least their mouths will grow a few millimeters. Although this size is nothing to people, it is a big size for mosquitoes with only a few millimeters. However, the biggest trouble is that fat is not a fluid, it exists in fat cells, which form fat tissue with certain mechanical strength, which is what we often say-it is impossible to succeed directly ... If mosquitoes want to suck fat, they must find ways to cut fat tissue into small pieces to "suck jelly" and even make fat cells into liquid ... This is quite difficult. At least the so-called "lipolytic acid" in the report can't be achieved, which may require powerful cutting tools or digestive enzymes and enough time ... These will inevitably increase the pain of the host body, prolong the operation time, thus increasing the probability of being found, putting the mosquito itself in danger ... and it is not easy to pull out its mouth when trying to escape ... But the biggest problem is that this is also nutrition. Why do mosquitoes remain more accessible and nutritious? Just to prove that biological evolution may be stupid?
Magic mosquito, there is a lot of fun on the internet.
So, to sum up, I feel that liposuction by mosquitoes is not very reliable. ...
However, some netizens seem to be doing more unreliable things, and the situation is very complicated ... It seems that online sellers are already selling "South African liposuction mosquitoes", and there are noses and eyes that the scientific name of this mosquito is Toxorhynchites. It seems that the seller also realized that mosquitoes can't penetrate such deep skin, so he chose this 3 cm long mosquito. There is also a nose that says it is a springbok from South Africa. This place is really there. It's near Cape Town. Pork belly can be eaten as a meal, each 15 yuan ... The problem is that this huge golden-bellied mosquito is produced in Asia, and this product is vegetarian ... Although its larvae in the water will eat the larvae of other blood-sucking mosquitoes, it should be regarded as beneficial insects, right? But adults eat vegetarian food like nectar instead ... Honey, do you just want to sell some pet mosquitoes? Or, just add a little joy?
Finally, even if the reported mosquitoes really exist, to be honest, I'm afraid they definitely don't make people thin, but suck people's skin into a beach like raindrops.
