Does the bite of the flower mosquito be particularly itchy, and what is the benefit of its own evolu

The strategy used by the flower foot mosquito and the ordinary house mosquito is completely different, the flower foot mosquito attacks during the day, the action is fierce, the pounce is sucking, the vigilance is not high, it is easy to kill, but the speed is fast, and it often escapes long after the itch, so it doesn't matter. Ordinary house mosquitoes are active at night, avoid light, high vigilance, often have to try several times before falling to suck blood, and run away at the slightest alarm, and then come again in another place, often a mosquito bites a lot of bags on the body, very annoying, not so itchy, and its habits are in line. Biological evolution mainly acts on the behavior and constitution of organisms, and the genes produced by constitution are difficult to change, even if a small number of individuals obtain this change, it is impossible to pass on this gene (the base is too small).

To put it bluntly, genes can affect the size and shape of the salivary glands, but it is difficult to change the substances secreted by the salivary glands (saliva). <

Flower mosquitoes bite even more.

Expansion: Aedes aegypti and Aedes albopictus are commonly known as flower mosquitoes. Aedes aegypti is dark brown with silvery-white spots on its body; Aedes albopictus is black or dark brown in color, and has white stripes and silvery-white spots on its body, so these two mosquitoes are also called "flower mosquitoes".

Hazards: Female mosquitoes are ferocious bloodsuckers, and they harass people a lot in places where they occur in large numbers. They are an important vector of dengue fever in China and one of the transmitters of dengue fever and chikungunya disease in Southeast Asia.

The scientific name of the flower mosquito is tiger mosquito, and the biology teacher just said that the spines on its nose are larger than ordinary mosquitoes, and they are sharp, and the toxin is also 3 times that of ordinary mosquitoes

The toxin in the mosquito body is called anticoagulant, and the concentration of anticoagulant in the body of the flower mosquito is the highest.

The scientific name of the mosquito is Aedes mosquitoes, which often moves at dusk, because before sucking blood, it will spit out some anticoagulant saliva, causing the human body to have an allergic reaction and appear "pimples".

Under normal circumstances, the pimple will subside automatically in about 15-20 minutes, and if the mosquito has bacteria when sucking blood, resulting in infection of the wound at the blood-sucking site, the pimple will turn red, and the itching will be unbearable for a long time.

The scientific name of the flower mosquito is "Aedes albopictus". It mainly sucks blood during the day, bites people fiercely, spreads dengue fever, and is known as the "Asian tiger mosquito". It breeds in natural stagnant water and small containers, such as jars, cans, cans, flower beds, bamboo tubes, tree holes, lunch boxes, waste tires, bonsai, clogged roof ditches, etc.

The spotted mosquito bites and sucks blood at night and during the day. The spotted mosquito is not only vicious, but also good at flying. Generally, mosquitoes only fly tens to hundreds of meters, and the farthest distance is not more than 1-2 kilometers, but the spotted mosquito can fly 5-7 kilometers, and the speed is extremely fast, and it can also do "difficult actions" such as rolling back and forth, diving, sharp turns, sudden acceleration or deceleration at will.
