The mosquito’s body is divided into 3 sections: the head, the thorax and the abdomen.
There are two feelers on the upper side of the mosquito’s head. These
feelers are rich in sensory cells, and are very sensitive receptors. The
male mosquito’s feelers are much more sensitive than those of the
female, bcause at mating time, thanks to these feelers, they can
perceive the frequency of the female’s wing beat in the midst of a
multitude of sounds.
In the female mosquito between the feelers there is a tube for
sucking blood. This sucking tube does not have a simple structure;
contrarily it contains a somewhat complex system. In fact it is the
casing for a very special cutting and vacuuming mechanism, called the
“labium.”When the mosquito bites, this sheath folds back and the cutting mechanism goes into action. This mechanism consists of 6 parts. Four of these are very effective cutting knives. They are strong enough to cut as easily into the skin of a frog or the scales of a snake as into the human skin.
The other two parts join together to make an empty tube. The mosquito sticks this tube into the wound opened by the knives enabling it to suck the blood of its victim.
One of the knives numbs the tissue with a salivary fluid it pours into the wound. This is a kind of local anaesthetic. In this way the mosquito cuts into the skin and you don’t feel a thing as it sucks your blood. As this fluid also prevents the blood from clotting, the mosquito is able to carry on sucking the blood. It is again this fluid that later causes irritation and swelling.
The mosquito has up to 100 eyes, which are
arranged on the head in honeycomb fashion. The picture below shows a
cross-section taken from the inside to the edge of this compound eye.
Below left shows the appearance of an object as transmitted from these
eyes to the brain.
This section joined to the head of the mosquito is where
the mosquito’s six legs are appended to, as well as a pair of wings.
These wings are covered in scales and have veins passing through them.
Some varieties of insect have two pairs of wings. However, in place
of a second set of wings the mosquito has stubby knobs which vibrate
during flight to help provide stability and balance.The mosquito has a hairy body. On the head, wings and legs there are scales like the scales of a butterfly.
The abdomen, which can withstand pressure
|
Only female mosquitoes suck blood for the purpose of providing nutrition to their eggs. The male mosquito feeds on nectar and water. |
Mosquitoes’ bodies have a great capacity to expand when
sucking blood. They can suck an average of 2.8 mg (0.0001 ounce) of
blood in one go, which is greater than their average body weight-2.5 mg
(0.00008 ounce) (This is like someone weighing 70 kg (154 pounds) eating
more than his or her own weight in food at a time, and in a short space
of time). How is it that an insect with such a delicate build can drink
its own weight in blood? What prevents the mosquito from bursting to
death from drinking such an excess of blood?
As in other bloodsuckers, the mosquito has a specially designed
digestive system. There are tension sensors that tell mosquitoes when to
suck blood and when to stop. These work in conjunction with the
digestive system.The skin on the mosquito’s abdomen is composed of a flexible and transparent membrane. When blood is drawn in, this membrane opens out to enable the abdomen to expand. By this means the mosquito can drink as much blood as it pleases.
Experiments have shown that if the tension sensors in the mosquito’s abdomen are removed, the mosquito explodes from sucking blood. In addition to all the systems pointed out so far, the existence of a capacity control system in the mosquito’s abdomen is further evidence of the supreme art of creation.
People use similar systems to the ones found in bloodsucking insects such as the mosquito in water storage facilities. Water drawn by pumps is transferred to storage containers, which have special sensors to control the water level. When the water in the storage container reaches the maximum level, the pump automatically stops.
|
In nature, mosquitoes provide a source of food for a variety of animals. A camouflaged spider traps a mosquito. |
Now let’s draw a rough comparison between the two
systems: The water motors usually weigh dozens of kilos or more. In
addition, they are extremely noisy and need an enormous amount of energy
to function. In time, the connectors to the pipe and the gaskets wear
out and the water starts leaking. Or else, they require maintenance for
reasons such as rusting.
The suction system in the mosquito’s head is smaller than one cubic
millimetre. What’s more, the pump does not require maintenance even once
in the lifetime of the mosquito. This system never wears out or stops
functioning. There is never any dysfunction in the system. Pumping
systems, which are the product of high technology, are extremely
primitive in comparison with this perfect mechanism.Without a doubt, neither mosquitoes nor other insects possessing these perfect systems can create them at will. There is a supreme Creator Who creates this perfect system in them. This Creator is God, Who controls all. The knowledge of our Lord is contained in everything. It is God, the Lord of the Universe, Who controls all and creates everything to perfection. This is expressed as follows in a verse of the Qur’an:
This is God’s creation. Show me then what those besides Him have created! The wrongdoers are clearly misguided. (Qur’an, 31:11)
Contrary to popular belief, mosquitoes do not feed on blood. The mosquito obtains its nourishment from nectar. Male mosquitoes do not suck any blood throughout their lives. However, female mosquitoes suck blood to supply the need for protein of the eggs during the egg-laying stage. It takes 3-4 days to digest the blood they suck. Then the bloodsucking operation is repeated. For female mosquitoes this cycle lasts to the end of the egg-laying phase.
Sensitive receptors to sense the location of prey
If you are asleep in a pitch-dark room at midnight, a
mosquito can find you easily. Even if your whole body is under the
covers with only your hand sticking out, the mosquito will instantly
find that piece of flesh and take blood from that source. Even though
the subject is one that is distasteful and which people may not wish to
give thought to, we must still ask how this animal manages to do this.
What is the secret that enables it to seize its prey in the dark?
The answer reveals another superior design to us: The mosquito is
equipped with a complex system that enables it to find its prey. This
system consists of receptors sensitive to heat, gas and various chemical
substances. By this means the mosquito can easily identify its prey in
the dark.|
One of the mosquito’s receptors is heat-sensitive. It perceives the heat given off by bodies. |
The use of heat-sensitive receptors is a somewhat
effective method that is frequently used nowadays in military
technology, particularly in the dark. A very sensitive heat receptor is
also found in the body of the mosquito. This organ, known as the
“tarsi,” is located in the forelegs of the mosquito. When these organs
detect the heat waves coming from a body, the mosquito is drawn by them
and reaches its target unerringly. Furthermore, thanks to this heat
detector, it can easily find the regions under the skin where there is
the most blood, as veins are warmer than tissue.
In other words, a mosquito entering a pitch-dark bedroom can
accurately perceive the exposed parts of a sleeping person’s body, even
to the point of finding the veins close to the skin.Another factor that attracts the mosquito is carbon dioxide gas. This gas present in the breath of humans and animals is particularly attractive to mosquitoes and serves as an important clue in the finding of prey. In an experiment to show the effect of carbon dioxide on mosquitoes, two humanoid models were placed two metres (6.5 feet) apart. Then carbon dioxide was emitted at breathing pace by means of a mechanism installed in the mouths of the models. Immediately mosquitoes began circling the heads of the models.
The cocktail of amino acids, amines, ammonia and lactic acid found in the blood also attracts the mosquito; even when the concentration of these substances is diluted 2,000 times, the liquid is 5 times more attractive to mosquitoes than pure water. Moisture is another important factor to attract mosquitoes.
In short, the mosquito is like a warplane loaded with heat, gas, humidity and smell detectors. Even if it cannot see its prey in the dark, it is equipped with superior systems for unerringly finding it in the dark. It can identify the location of its prey from a distance of approximately 25 to 30 metres (82-98 feet).
|
Any creature within a maximum range of 30 metres (98 feet) can fall victim to a mosquito. Above left there t is a mosquito biting a fox on the nose. Above right, mosquitoes drink the blood of a frog from around the eyes. |
It is obvious that such a special structure cannot be
formed as the result of a chain of coincidences. Let’s examine the
impossibility of this.
We know that the female mosquito needs to suck blood from her victims to
satisfy the protein needs of the eggs. In order to obtain this blood it
is necessary to find a victim.
If we take the claims of evolutionary theory seriously, the
perceptive skills of the mosquito detailed above must have been acquired
in stages. But the mosquito doesn’t have the time to wait thousands of
years for its body to acquire a heat receptor by chance. If it didn’t
have this system of perception from the beginning, the mosquito would
not find its prey and the eggs would die. That is to say, it is not a
question of development over time.Let’s repeat once more the receptors possessed by the mosquito; heat, humidity, gas and chemical substance receptor systems. And in addition to these, vibration feelers for perceiving the opposite sex.
The fact that a mosquito is equipped with such an effective receptive system means that its needs are catered for from the first phase of its development. The Creator of this perfect system Who brought the mosquito into existence is God. Just as God has provided for every living thing on Earth, He has also given them the necessary skills and equipped them to make use of this provision. This fact is made known as follows in a verse of the Qur’an:
There is no creature on the Earth which is not dependent upon God for its provision. He knows where it lives and where it dies. They are all recorded in a Glorious Book. (Qur’an, 11:6)
Biting the prey
When the mosquito senses one of the stimuli such as
heat, gas, moisture and chemical secretions, it heads straight for its
prey. The mosquito lands on its prey so gently that in most cases it is
not even felt. Then it finds the most appropriate place to pierce using a
pair of devices located in the mouthpart, which are called “palpi.”
The first incision is made with the upper and lower jaw. The four cutters in the sucking tube cut deep into the skin. The sensory organs of heat, smell, taste and touch play an important role in establishing where the capillaries are concentrated under the skin. After a few attempts the mosquito finds the vein.
The mosquito sucks the blood by sticking the tube into the hole it
has opened in the skin. Thanks to this tube it can penetrate a small
vein and drink blood directly. Or it can drink the blood that
accumulates in the surrounding tissue when the skin is cut.The first incision is made with the upper and lower jaw. The four cutters in the sucking tube cut deep into the skin. The sensory organs of heat, smell, taste and touch play an important role in establishing where the capillaries are concentrated under the skin. After a few attempts the mosquito finds the vein.
Usually the piercing needles go into the skin vertically. The most important characteristic of the mosquito’s needle is that it can bend at a certain depth. Thanks to this remarkable feature, the needle can easily move around under the skin, even to the point of being able to extend parallel to the skin. In this way the needle is able to get to the places where there is the highest concentration of veins.
But the mosquito acts as if it is aware of this and injects an anti-coagulant secretion into the wound from within one of its sharp knives. Thus the enzyme in the blood is rendered ineffective and the clotting stops.
What’s more, with this secretion the mosquito even gives a local anaesthetic to its victim, numbing the area it cuts into. Accordingly the victim is not aware that its skin has been cut and its blood sucked. It is this secretion that causes an allergic reaction in the skin and causes the skin to itch.
In the few seconds in which the above takes place, a person cannot even realise that he has been bitten by a mosquito.
A female sucks about 2.8 mg (0.0001 ounce) of blood in one go, and this takes about 2.5 minutes. When the sucking finishes, the blood is sent to the midgut by suction pumps located in the fore-section of the digestive system. The abdomen fills with blood as far as the digestive system. It takes 3-4 days to digest the blood and then the sucking process is repeated.
In a mosquito’s sucking tube there is a cutting
mechanism consisting of 6 knives. 4 of these knives cut into the skin
and the other 2 join to form a hollow tube, which the mosquito sticks
into the tissue it has cut and sucks out the blood.
If we stop and think for a while about all these processes, we will come to some important conclusions.
The mosquito doesn’t just have a superior receptive system and a
cutting and sucking mechanism to get the blood it needs; it also has
chemical knowledge. As explained above, the mosquito uses a secretion,
which prevents the blood from coagulating. What’s more, this secretion
protects it from an enzyme in the defence system of a body unknown to it
and of which it has no intimate knowledge. This secretion even has the
property of anaesthetising the living tissues it cuts like a surgeon.The answer is obvious: The mosquito cannot be the genius with information on the chemical composition of the human body that evaluates this information and develops solutions in its own body. It is evident that the system that enables this secretion to exist in the mosquito and to be injected into the veins of its preys can only be the creation of a Supreme Creator Who has the most detailed knowledge of the anatomy of both humans and mosquitoes.
1) The mosquito cuts tissue with a cutting
system consisting of 6 knives. In the process of cutting, the secretion
poured into the wound from one of the cutters numbs the tissue and the
victim is not even aware that his blood is being sucked. The secretion
also prevents the blood from clotting and enables the blood sucking to
continue.
2) The abdomen starts to fill with blood.
3) Eventually the mosquito’s abdomen fills with blood equivalent to more than its own body weight.
Humanity! An example has been made, so listen to it carefully. Those whom you call upon besides God are not even able to create a single fly, even if they were to join together to do it. And if a fly steals something from them, they cannot get it back. How feeble are both the seeker and the sought! They do not render to God the homage due to Him. Yet God is Powerful, Almighty. (Qur’an, 22:73-74)
Naturally, this miraculous ability is realised with the help of various support systems innate in the mosquito.
First and foremost, the muscles and connectors that make the wings flap have to be extremely strong and resilient.
The second condition is that these muscles have to be provided with energy. As we know, cells use oxygen to synthesise energy. Resilience increases in direct proportion to an increased capacity for the use of oxygen.
In the human body, oxygen from the lungs is taken into the blood whereby it is carried to the body cells. The reason a person gets tired when running is that the necessary oxygen is not carried to the cells in time. Another reason is the appearance of lactic acid in the cells of the muscles. If the cells cannot get rid of this acid, a feeling of fatigue ensues.
This situation is somewhat different for mosquitoes. In order to beat their wings, which are nearly the size of their bodies, 500 times a second, the mosquito needs a great deal of oxygen.
Accordingly, the mosquito’s respiratory system is created specifically to meet this requirement. The respiratory system consists of a respiratory tube that reaches almost every cell. As this tube makes direct contact with the outside air, the cells are able to get oxygen without an intermediary substance. And waste substances can also be passed from the cells into the atmosphere by means of these tubes. This is how the mosquito manages to flap its wings thousands of times a minute without tiring.
The fact that the mosquito can beat its wings so rapidly gives it many advantages in flying. It can fly up and down vertically, and can move forwards and backwards with ease. The mosquito is like a perfect machine that has many flight features superior to those of a helicopter or a plane.
For a helicopter or a plane to fly, specially refined fuel is used. Before each flight, it has to be refuelled with this somewhat expensive fuel. On the other hand, the mosquito gets all its energy from the nectar it feeds on. Planes and helicopters undergo maintenance before every flight, and the engine parts are periodically renewed. Encountering no such problems, the mosquito keeps on flying throughout its life, thanks to the strength of the muscles on its back.
Present day aircraft have acquired their current features as a result of years of research and lengthy experimentation. The pool of knowledge utilised has accumulated over hundreds of years. At every stage of development, human brain power and design has been employed. But however advanced technology may be, man is way behind the flight technology found in nature. No existing technology can make a machine with the dimensions and the flight characteristics of a mosquito.
It should not be forgotten that the being we are comparing with machines is a 10 mm (0.4 inch) creature composed of millions of small living parts (cells). With its circulation, excretory and nervous systems, a heart that constantly beats, eyes that see, its receptor systems and millions of cells synthesizing proteins, it is a far more complicated fusion than a plane or a helicopter.
When asked how planes or helicopters are made, people will say that they are made by senior engineers in advanced factories. They know only too well how ridiculous and illogical it would be to claim that these aircraft were formed as a result of the chance fusion of metals. But a percentage of the same people will claim that the mosquito, which is not even brought into the debate as being superior to the two types of aircraft, came into existence as the result of “coincidences occurring in the evolutionary process,” in other words, without any kind of planner. For it is difficult for them to accept the existence of a planner, that is to say, the existence of God, because that would entail cleansing themselves of their “ideological” reasoning, which would be contrary to their interests.
They are only deceiving themselves in so doing. The mosquito is an insect that came into existence after going through a number of miraculous phases in a swamp or a pool of water. Whatever stage technology may develop to, it cannot bring a living thing into existence, not even a single fly. Because creation is the preserve of God, the Lord of the worlds. And every creation is evidence of His existence. The judgement given in the Qur’an; “… Those whom you call upon besides God are not even able to create a single fly, even if they were to join together to do it…” (Qur’an, 22:73) is valid for all eternity for those who deny His existence, and shows the extent to which they contradict and deceive themselves.
