The shadows of the night have fallen and darkness reigns. He retires early hoping to enjoy hours of restful sleep. A familiar moan of corn breaks the silence in the warm, warm night. Your room has been invaded! Tense, worried, fearing the worst, you're waiting. You feel nothing and think that the danger has passed. But too late you realize that you have become a victim. The relentless itching reveals that he has not escaped the bite of what he might be inclined to call the "threat of nocturnal insects": the mustard.
From now until the end of the summer, you can be sure that all open windows will be protected. In fact, you can use oils and sprays on the exposed body parts, all to stop the attacks from the threatening mosquito. Obviously, you are not the first to lead the war. It is said that the Egyptians used pots and mosquito nets for the same reason, about thirty centuries ago.
However, your best defense may be a better knowledge of that enemy. How are the real mustiks? Why do they "bite" people? Are these insects used for useful purposes?
From egg to adult
Mosquitoes are insects of the order Diptera, which means "with two wings." There are more than 2,500 species and they are widespread. You can find them nesting in warm tropical pools or cold Arctic waters!
The mosquitoes go through four stages: (1) eggs, (2) larva, (3) pupa and (4) adult. Through ovipositor in the abdomen, the female can lay 100 to 300 eggs at a time. Some species form their eggs in a kind of raft, combined with a substance released by the female. The eggs can be laid in a swamp or even a small mare in a hollow ditch or log. Hatching can occur in two to three days, for species such as sea mold. Some of their eggs, deposited in a dry pond, hatch only after they have been soaked three times. Otherwise they can hatch for a short period of rain and the larvae would die when the tank dries up again. The music of the river lays its eggs in the mud of a river and they do not hatch until a new flood occurs, perhaps years later.
Often called gnarled for their movements in the water, the musical caterpillar has a appearance that repels worms. Around your mouth are small hairs that sweep away food: small plants, unicellular creatures called protozoa and even other flickers. To breathe, some mosquito larvae develop a kind of breathing tube or air tube above the water. In a wood map, however, the trachea is sharp and the larvae bite into a bulrush, bulrush or other plant to get oxygen. Many mosquito larvae die or lose their skin four times in four to ten days.
After the last melt, the creature becomes a chrysalis. Breathe through the tubes in the chest that are sent upwards from the water surface. In some species, these tubes are used to obtain oxygen from underwater plants. Due to the way the pupae of most mosquito species roll, they are called kalyce. They eat nothing and experience a good change in a few days.
The adult mosquito emerges from the puppy's shell. It starts to fly after the wings have dried. Mr. Mosquito can only live ten to twenty days and his friend a month or more. Of course, the lifespan varies by species. Some girly songs can survive the winter in your garage or barn.
"A boy meets a girl"
Mosquito devotes himself to his female counterpart for the first two days of his adult life. The small hairs on the antennae take a long time to dry, so you can feel. But let the girl fly! The wings have been shown solely to give a sense of proportion. In Mustique slang, the message should be "It's a girl!" Mr. Mosquito quickly takes the woman and mates with her.
The New Zealand Opifex mosquito is eager to mate. The males continue to fly over the water of the litter and wait for the nymphs to rise to the surface! Eager men mate with women before successfully leaving the newly opened pupil shell.
A physical evaluation
The body of an adult mosquito consists of the head, chest and abdomen. There are two compound eyes with thousands of lenses on top of the head, each eye can function independently. There are two antennae between the eyes that the insect uses to hear and smell.
The most dangerous part of the mosquito's anatomy is a funnel-shaped mouth. With a wide head, it narrows in a tubular trunk. By the way, only Mrs. Mosquito can "bite" you. The "boys" in the "family" cannot cause such torture. But we'll talk about that later.
A short neck connects the head to the chest. The three pairs of bones and the two wings of the insect are attached to it, through which the blood vessels are clearly visible. The waves, sometimes very colorful, cover the edges of the wings and veins. The moaning is heard when a mosquito approaches is the sound of its wings beating. The rod-shaped parts (halter) behind the wings allow the insect to maintain its balance. During flight, they vibrate at the same speed as the wings. By developing harmonious vibrations in the air and in the chest, the mosquito is said to "generate more fins than its nerves or muscles could handle alone."
The mosquito's long, tubular stomach holds the stomach and intestines. The insect breathes through small holes called spiracles. There are eight pairs in the abdomen and two pairs in the chest.
The mosquito body is covered by an elastic layer. And these annoying insects come in different colors. Most are black, brown, brown or gray, but some are green or blue. White or light spots appear on the back, wings or legs of many species, although it is unlikely that you will admire their decorations if they are attached.
Are all mosquitoes carriers of disease?
This question can be asked because most people have heard that these insects carry various diseases. During an outbreak of yellow fever in New Orleans, Louisiana, the "culprit" turned out to be a mosquito species that apparently preferred to place its eggs in a pot. Well, these insects were reproduced in the water in the flower pots placed on the grave of the victims of the yellow fever!
In 1878, the mosquito Culex quinquefasciatus was discovered to transmit filariasis, a disease that causes swollen glands and limbs and sometimes leads to elephantiasis. In nine years, certain types of Anopheles mosquitoes have been identified as having malaria. In 1900 we learned that yellow fever was transmitted by Aëdes aegypti.
Some mosquitoes transmit a dozen diseases to humans. In fact, very few species are carriers of the disease. Therefore, you do not necessarily have to worry about this insect attacking you. Still, you may be wondering why these creatures are primarily looking for you. In fact, one may ask:
Because you are so attractive
The researchers concluded that body heat and moisture from human skin are factors that attract mosquitoes. They can also be attracted to lactic acid in human sweat and respiration, as well as carbon dioxide that is exhaled by animals and humans. In fact, the amino acids and hormones found in body fluids can attract mosquitoes. There is nothing you can do about it if you continue to breathe.
Women can be comforted by the fact that Mosquito generally finds men more attractive. In addition, these insects usually attack the most "attractive" individual in a group. Thus, you can escape while an employee is practically "eaten". Of course, this attraction has nothing to do with beauty or beauty. But how can anyone be disappointed if they do not cope with the threatening mosquitoes?
How Mrs Mosquito bites
Since you've probably been exposed to the mosquito, you should know how it happened. Well, the source of the irritation is not a mouth that opens and closes like you do. Instead, it's the strain of the female mosquito that causes the agony. The center consists of six stiletto heels, hands closed in a six-minute band. Specifically, there are two spindle jaws, two jaws, an upper lip, and the last a lancet with a salivary duct. When not in use, these stiletto heels are covered by the lower lip, which is immediately removed if Ms. Mosquito decides to "leave them alone." the wound, unless it touches a sensitive area because the "lady" gives you a fast-acting anesthesia.
The puncture is complete, Ms. Mosquito's saliva is flowing freely through the wound. Since this will thin the blood and prevent it from clotting, you can easily pick it up through the groove in the upper lip, as a person can drink the soda through a straw. After drinking, the "lady" takes out the "needle" and happily flies off with three or four times the weight of her blood. This inadvertently increased the mosquito population because Ms. Mosquito needed her blood to develop the eggs in her body.
Since only female mosquitoes attack humans and animals, you can adopt a friendlier attitude towards males. Its price is the nectar of the plants. In fact, these juices are also the staple food for the female mosquito, but you might be amazed after an encounter that makes you itchy.
Compete with the enemy
To protect themselves from the threat of insects at night, people in the tropics often sleep under mosquito nets. In addition, many other measures are taken to prevent diseases transmitted by mosquitoes. One way to prevent yellow fever is to use a vaccine. Malaria control ranges from the use of insecticides to drainage and spraying chemicals or oil in breeding areas. A thin film of oil in the water prevents the larvae from breathing because they cannot bring air to the surface.
The control of filariasis is highly dependent on the use of insecticides and insecticides. Humans fought mosquitoes by clearing swamps or spraying insecticides on large fields and forests. People spray insecticides in their homes in the hope of getting rid of mosquitoes.
How do repellents work? Well, the flow of humid, warm, carbon dioxide laden air around a person attracts mosquitoes. The sensory hairs of their antennae pick up the current, and the insects eventually find the source. However, insecticides generally repel female mosquitoes because they seem to prevent their "emotional" moisture sensors from functioning normally. In a way, he has the idea that he lost his object and that he is flying elsewhere.
Experiments of Dr. W. A. Brown of the University of Western Ontario show that the types of clothes you wear affect your "attractiveness" with mosquitoes. Allen Rankin writes: “In his experiments, Dr. Brown found that one-tenth of mosquitoes were more likely to be found in white clothes than in the dark. In general, the lighter the color, the less attracted to mosquitoes. The most avoided texture: light satin. "- wonders and secrets of our fauna.
Are good?
That's a good question, and many will probably say, “No. Mosquitoes are not good! However, some researchers suggest that the male mosquito, the cost of which is the sap of the plant, plays a role in the pollination of certain types of wildflowers. Mosquitoes are also an important source of food for some animals, birds, other insects, and even fish.
Not all mosquitoes are dangerous villains. Although these insects can be harmful, they serve some useful purposes. At the very least, you don't have to fear all mosquitoes, even if you consider your species a nighttime threat.
