Mosquitoes and Their Teeth
Mosquitoes are second in a list of an essential enemies for human beings, ideal after other person beings.
According to one estimate, over 1 million world die every year due to illnesses caused by mosquitoes. This is not because they suck too much of ours blood, leading to hypovolemic shock (shock due to sudden decrease in blood volume), but since they present a big variety of unwelcome guest in the kind of diseases.
For example:Plasmodium, which can cause malaria.Dengue virus, which can reason Dengue fever.And many other debilitating or fatal diseases.
Let’s gain silly because that a moment. Imagine a mosquito going come a sink with a brush and toothpaste come clean the teeth. Doesn’t that seem hilarious?
This idea is based ~ above a myth the mosquitoes have true teeth. Intend by words “tooth,” we mean that hard calcified structure installed in fleshy gums provided to rest food under into little particles. In the case, that becomes difficult for a mosquito come have also a solitary tooth.
However, the expression “Mosquitoes have actually 47 teeth” can become an ext accurate if we modify our principle of what a tooth actually is.
Mosquitoes have something that acts similar to our teeth do. To understand that, us must plainly understand insect mouthparts, in general, and also for a mosquito in particular.
Basic Insect Mouthparts
Insect mouthparts are made up of 5 structures:Labrum: upper lipLabium: lower lip that additionally serves together a sensory structureMandibles: hard, strong jaws supplied to cut foodMaxillae: used because that holding, manipulating, and movement of the food throughout mastication (chewing)Hypopharynx: involved in the swallowing procedure and likewise associated with salivary glands
Keep in mind, mosquitoes don’t drink blood. Other insects such as biting midges and also horse flies bite the skin, lacerate it, and also then drink the blood that pools in ~ the site.
But, mosquitoes choose to attract the blood straight from the blood vessels.
In the mosquito, these mouthparts space modified to a structure called proboscis committed for sucking blood by puncturing the skin, especially in mrs mosquitoes.
The mrs mosquitoes sucking blood due to the fact that they need protein for their eggs.
The proboscis of masculine mosquitoes isn’t solid enough to pierce the skin. That is used instead to drink nectar and fruit juices.
So what is in the woman mosquito’s proboscis?
The proboscis in mosquitoes comprises 6 needles encased in a sheath and is solid enough to cut through clothes and skin all the method to the wall surfaces of blood vessels.
The mouthparts mentioned above are present and also perform a similar but contempt modified function during bloodsucking.Labrum surrounds six needles and also acts as a sheath. This sheath is not put into the skin during the bloodsucking. Rather it features as a guide and also has receptors for taste. Mandibles (a pair) are dedicated to cut through the skin and are thrust forward as far as feasible in search of a blood vessel. Maxillae (a pair) space not as sharp as the mandibles however end up choose a knife v a sawtooth appearance. There are 47 teeth-like frameworks on the maxillae which do two important functions:Cutting with the skin as mandibles and also helping in the research of the proboscis. The maxillae room thrust before the mandibles in the forward motion of the mosquito’s head.They organize the proboscis when the mandibles room being progressed and perform not slip earlier during mandible forward-pushing. This is completed by those 47 tiny saw-like teeth structures existing at the edges of maxillae.

These saw-like structures on the edges of maxillae are taken into consideration to be “MOSQUITO TEETH.”Labium acts as a suction pipe through which the fresh blood is sucked into the mosquito’s gut.Hypopharynx plays a vital role in preventing the blood from clotting at the mosquito bite site setting the structure for the consistent availability that blood come the mosquito. Hypopharynx pumps the saliva into the borehole. This saliva has anticoagulants that stop blood clotting.
All this needle-like frameworks play a crucial role in the overall procedure of bloodsucking. They are placed for a really brief interval, and also the human realizes the bite just after it has occurred.
In other words, the so-called teeth (serrated edges of maxillae) space so small that a human being is unaware of their insertion into the skin.
Then, why perform we feeling itchy in ~ the site of the mosquito bite? Is it as result of the mosquito’s teeth?
No, the itching and also swelling in ~ the mosquito’s bite are due to the body allergic reaction to the chemicals present in the mosquito’s saliva. Also, the itching and swelling room felt after ~ the bite has occurred, not throughout the bite.
So, mosquitoes don’t have true teeth. Still, they have actually something the acts choose teeth that room the sharp experienced teeth-like structures present at the edges of maxillae provided to cut and support the proboscis during bloodsucking.
