Who knows how many teeth mosquitoes have? How many teeth do mosquitoes have?

Mosquitoes are toothless! It is usually said that the bite is with its beak! The details are as follows:

The mosquito beak is a stinging mouthpart and is an important structure for the transmission of pathogens. It consists of an upper inner lip (upper lip pharynx), 1 tongue, 1 pair of upper and 1 pair of lower jaw, which together form an elongated needle-like structure, which is encapsulated in the sheath-like lower lip. The upper inner lip is elongated, the ventral depression forms the inner wall of the food tube, and the tongue is located below the upper inner lip, which together with the palate seals the open underside to form the esophagus to draw blood.

The ** of the tongue has a salivary duct. The end of the upper jaw is wide like a knife, and its inner side has a fine serration, which is the first tool used to cut ** when mosquitoes suck blood. The end of the lower jaw is narrow and thin-knife-shaped, and its end has a coarse serration, which is the function of sawing and stabbing with **after cutting**.

The surface of the lower lip is covered with scales, mostly dark, and its end is split into two pieces, called the labellae. When the female mosquito sucks blood, the needle-like structure pierces the **, and the lip flap holds all the sucking organs outside the **, and the lower lip bends backwards and stays outside the skin, which has the effect of protecting and supporting the stinging and sucking device. However, the upper and lower jaws of male mosquitoes have degenerated or almost disappeared and cannot be pierced**, so they are not suitable for blood sucking.

On both sides of the beak there is a pair of tentacles (mandibular whiskers), which are appendages of the lower jaw. The tentacles of the female and male mosquitoes are the same length as the beak, but the last two segments of the male antennal are enlarged and curved outward; The tentacles of Culex mosquitoes and Aedes mosquitoes are shorter than their beaks, while the tentacles of male mosquitoes are longer or equal in length (with the exception of a few mosquito species). The tentacles are sensory organs that stab and suck.

Mosquitoes have 22 teeth. are all distributed on straws.

Mosquitoes have 22 teeth, and these 22 teeth are distributed on top of blood-sucking straws.

Mosquitoes are a diptera of the phylum Arthropods.

Its mouthparts are stabbing and sucking mouthparts.

The concept of teeth did not begin to appear until the more advanced phylum Chordates, and the term that mosquitoes do not have teeth may be described in the books you read as teeth, not real teeth in the biological sense.

Mosquitoes have no teeth.

The mouthparts of insects are composed of a large jaw (a pair), a small jaw (a pair), an upper lip, a lower pharyngeal tongue, and a lower lip (a healed second jaw with a pair of lip flaps at the end). In order to adapt to the blood-sucking environment, the mouthparts of mosquitoes have been specialized into stabbing and sucking type, and their functions are mainly in piercing ** and sucking blood, therefore, mosquitoes have no teeth.

Mosquitoes have 22 teeth.

The mouthparts of mosquitoes are delicate and complex, in which the hypopharyngeal tongue is located in the middle of the inner side of the lower lip, which is tongue-like and has a tooth-like object at the end, which has the function of regulating the opening of the saliva duct, and when the mosquito sucks blood, the dengue virus enters the human body along the saliva duct with saliva.

The cutting function of the mosquito's mouthparts is performed by the large jaw and small jaw, and the ends of these two structures have fine tooth-like matter, and the large and small jaws of male mosquitoes have degenerated, losing the function of puncture, and only by ingesting nectar to maintain a short life.

Dangers of mosquitoes:

It is important to note that the main hazard of mosquito bites is the easy transmission of diseases. At present, there are generally three types of mosquitoes that can transmit diseases:

1. Anopheles mosquitoes can transmit malaria.

2. Culex mosquitoes, which can transmit filariasis and Japanese encephalitis.

3. Aedes mosquitoes: It should be noted that it can transmit Japanese encephalitis and dengue fever. After the human body is bitten by mosquitoes, it will cause local tissue redness and swelling, and it can be applied externally with flower water**.

In addition, mosquito bites can also be prevented by applying toilet water. When going out hiking, it is recommended to wear long sleeves and long pants to avoid more **exposure as much as possible to avoid being bitten by mosquitoes and affecting your health.
