Do mosquitoes have a sense of smell? Do mosquitoes have a sense of smell

It should be there, otherwise you wouldn't know that people are **.

Mosquitoes have a sense of smell. Mosquitoes identify scents to find prey, courtship and fun, a unique hormone emitted by female mosquitoes can attract male mosquitoes a kilometer away to the side, the sense of smell is mainly used to find the general direction of the target, close to the target and use the eyes to accurately locate. There are about 2,700 species of mosquitoes that also have fairly sensitive visual receptors and thermal sensors.

Mosquitoes: Insects of the Diptera mosquito family, there are more than 3,600 species. It is an important medical insect because of the blood sucking of female mosquitoes.

Transmission of yellow fever, malaria, filariasis and dengue fever. The body of the mosquito is slender, covered with scales, the feet are slender and fragile in appearance, and the mouthparts are inside the long snout. Male mosquitoes have filamentous antennae with ring hairs, and are generally denser than female mosquitoes.

Male mosquitoes feed on nectar and plant sap, and females sometimes eat as well, but most eggs only mature after sucking blood once. Different mosquito species have different host preferences, but there are no strict restrictions in many cases. The eggs are laid on the surface of the water and hatch into aquatic larvae (孑孓).

The larvae swim in rapid writhing motions, eat algae and organic detritus, a few carnivorous, and even eat other mosquitoes. Unlike most insects, pupae are mobile and breathe through a snorkel on their chest. Adult mosquitoes mate as soon as they emerge from their pupal shells.

Lifespan varies greatly depending on the species. Mosquitoes appear to be attracted to the host's moisture, lactic acid, carbon dioxide, body heat, and movement. Mosquitoes seem to find their host by their sense of smell.

The mosquito call is caused by the rapid flapping of the wings; Females fan less frequently, so they can be identified by males.

Some people have a large lung capacity or a faster breathing rhythm itself. In this way, the exhalation of carbon dioxide is relatively large, and the carbon dioxide will form an air stream about 1 meter or so on the head, which mosquitoes are more sensitive to and will smell it.

Mosquitoes like to sweat people, the acidity in the blood is enhanced, and the sweat excreted makes the body surface lactate value high, which is attractive to mosquitoes. In addition, there is a heat receptor in the antennae of the mosquito, which is very sensitive to temperature, as long as there is a slight temperature difference, it can be immediately noticed, and the sweating body dissipates heat quickly, which will also attract mosquitoes.

Mosquitoes have a darkening habit, and if they wear dark clothing, they will show a dark shadow at night, and the mosquitoes will chase towards darker places. Clothing colors such as black are the preferred targets for mosquito attacks, followed by blue-violet, blue, red, green, etc., mosquitoes do not like to bite white. Similarly, mosquitoes love to bite people with darker skin or reddish skin.

Hazard: Some species of mosquito insects are vectors of malaria, filariasis, yellow fever, chikungunya, dengue fever, Japanese encephalitis, and many equine spinal encephalitis.

If the female mosquito bites a sick person when sucking blood, the pathogen may enter the mosquito body through this action and be transmitted through the mosquito's bite. But not every mosquito can transmit every virus. Only certain species of mosquitoes, called vector mosquitoes, can transmit specific species of viruses.

If the virus is absorbed by a non-vector mosquito, it will be damaged by enzymes in the mosquito's digestive system and lose its infectivity. Since only females suck blood, only females can transmit diseases.

In summer, mosquitoes are particularly annoying, and they can attract a group of mosquitoes when they go to **, and they will be bitten by mosquitoes if they don't pay attention to it, which is really miserable, but if you light a mosquito coil or use mosquito repellent, the mosquitoes will be much better, do mosquitoes have a sense of smell? Mosquitoes have a sense of smell, and their sense of smell is very powerfulLet's learn more about mosquitoes.

1. Olfactory system

Mosquitoes have a very sensitive sense of smell, and mosquitoes rely on their olfactory system to search for targets. People will sweat in summer, that is, the smell of sweat can be attracted by mosquitoes within a radius of dozens of meters, you can know how powerful the mosquito's sense of smell is, mosquito smell is mainly used to find the general direction of the target, and use the eyes to accurately locate after approaching the target.

2. Visual system

The mosquito's visual system is incredibly powerful, and its eyes occupy 3 4 of the entire head, so the mosquito has a very large viewing angle and can almost see things behind it. And not only that, mosquitoes can also see infrared radiation that we can't see, so mosquitoes have this ability, so they can also find targets at night and bite. The heat radiation of the blood vessels of the human body is greater than that of ordinary **, so mosquitoes can accurately find the blood vessels and start sucking blood.

3. Auditory system

Mosquito hearing is also very powerful, the main function is to transmit information, mosquito Hu Kai code is through wing vibration, and hearing to communicate, tens of thousands of mosquitoes in a group of flight will not collide, this is relying on a strong hearing system. However, mosquitoes do not have a large hearing range and can only perceive nearby sounds, but this function is enough for mosquitoes.

Laundry detergent flavor, sweet flavor.

Mosquitoes locate people mainly by feeling some chemicals (smell, etc.).

People with well-developed sweat glands and high body temperature. The sweat expelled creates an attraction for mosquitoes.

People who are tired or have a fast respiratory rate. Exhaled carbon dioxide is relatively high, and mosquitoes are more sensitive to it.

People who like to wear dark clothes. Mosquitoes have a tendency to darken, and if they wear dark clothing, they will go to darker places.

Other factors, such as the smell of cosmetics and the smell of alcohol, can also attract mosquitoes to bite.
