How do mosquitoes survive in the cold winter?

Most of the mosquitoes freeze to death in winter, and only a few remain. In fact, mosquitoes are in a dormant period in winter, and most mosquitoes hibernate in the form of eggs and grow adults in summer.

Mosquitoes are one of the most hated creatures for many of us, and we all know that summer is their peak season, especially in some places in the countryside where there are trees, flowers and plants, it is really outrageous. But under normal circumstances, in autumn, after the Chongyang wind rises, it is rare to see the presence of mosquitoes. There may be a few of them occasionally in autumn, but there is absolutely no winter with them, and many people are curious about whether he will become extinct after winter?

Of course not.

One: Mosquitoes will not go extinct.

This kind of creature does not exist with the season, because the conditions they are suitable for survival are about 20 degrees, if the environment is more suitable, then they have room to grow, like summer, it is very suitable for them to grow. In winter, because the temperature is too low, they just hide and people can't see it, so they think they are extinct.

Two: There is heating in the north, which is suitable for survival.

We all know that the winter in the south is very cold, while in the north it is heated, basically every household has it, otherwise, people can't stand it. After the heating is turned on in that house, they have reached the living environment they need, and naturally they will come out to shake, and when the temperature drops, they will stop breeding. All of them will hide in those warmer and darker places, and some of the metabolic levels in their bodies will also drop to very, very low, at this time, they will be like hibernating, and they don't need to eat at all.

Three: No need to hibernate, incubation at the right time.

But they don't really need to hibernate, they lay eggs before the weather gets cold, some of these eggs will freeze to death, but the rest will be preserved. When the temperature is warmer, it will hatch and it will be able to hatch in about 10 days. In fact, as long as the temperature is within their acceptable range, we can still feel this nasty creature in the cold winter.

Generally, they will find a warm place to hide, such as heating pipes, and in the cracks of walls, mosquitoes will lay their eggs in the water, and the activity of these mosquitoes is relatively small.

They will hide in warm places and spend the winter, and when the winter is over and in the summer, mosquitoes will reappear.

I think mosquitoes survive the winter by hiding in warm places, because mosquitoes simply can't stand the weather in the north.

Mosquitoes spend the winter normally in the north and do not hibernate because the winter in the north is heated.

The average lifespan of a mosquito is about a week, otherwise the world would be the world of mosquitoes. 2.The temperature for mosquitoes to be active should ideally be higher than about 30 degrees.

In the south, the winter temperature does not reach, so the number of mosquitoes decreases significantly in winter. 3.In addition, with the reason of the season, after a large number of mosquitoes appear in summer, they begin to lay eggs in the water, and a large number of mosquito eggs appear, and the life span of mosquitoes is not long, so adult mosquitoes will appear green and yellow after death, so there are few mosquitoes in winter.

4.Mosquitoes spend the winter with their eggs in the water, and in the summer they become mosquitoes. However, there are still very few mosquitoes in winter, especially in the south.

In areas with distinct seasons, mosquitoes alternate between breeding and overwintering periods due to the influence of natural environmental factors. In winter, when the temperature is too low, mosquitoes stop breeding, and adult mosquitoes gather in warmer, more stable places with a relatively stable microclimate. When temperatures warm up in early spring, surviving adult mosquitoes begin to suck blood, lay eggs, and reproduce offspring.

The overwintering mode of mosquitoes varies from species to species, for example, Culex pale mosquitoes mostly overwinter as adults, Anopheles microphyllum and Culex tribal mosquitoes mostly overwinter as larvae, and Aedes albopictus overwinters mostly as eggs. During wintering, most mosquitoes die naturally, and only a few survive until the following spring. The overwintering period is the period when mosquitoes are least abundant and most vulnerable.

Mosquitoes overwinter in inhabited areas and are known to be home to 42 species in New York alone. At the same time, all mosquitoes need to hibernate, more precisely, overwinter! When the weather cools down in autumn, especially when the temperature drops below 10 degrees Celsius, mosquitoes will die in large numbers, and only a few strong mosquitoes survive.

Mosquitoes are "adult wintering", that is, adult mosquitoes hide in dark and damp places such as corners and basements to spend the cold winter, and in early spring, they come out of various hidden places such as cracks in the corners, bathe in warm sunlight, feast on the blood of humans and animals, and then begin to lay eggs.

In fact, there are many mosquitoes that can't survive the winter, and a large number of mosquitoes will face death when winter comes, but there are also a very few adults with high IQ and strong body that can survive the winter. They are mainly hidden in the cracks of the walls that are sheltered from the wind and the sun, or in hidden places with heating. There are also eggs for the winter, mosquitoes generally lay their eggs in the water, as the temperature drops and the river freezes, the mosquito eggs will also be frozen, but they will not die, and when the weather gradually warms up in the next spring, the river thaws, and these eggs will be hatched.

Hide in a corner of the room to protect yourself from the cold. Mosquitoes are very small and relatively easy to find a place to hide.

Mosquitoes in winter fly out of warm crevices and other places.

Under normal circumstances, when the temperature drops below 10 degrees Celsius, the mosquitoes will basically freeze to death.

But there are also a very small number of mosquitoes because they have sucked enough blood in advance, stored nutrients, and are hiding in some warm crevices and behind cabinets in the room, so they survived by luck, and when the indoor heating or air conditioning was turned on, the indoor temperature rose, and they flew out of the small hiding place.

Mosquitoes are more harmful:

Mosquitoes can spread diseases, because mosquitoes like to live in a dark and damp environment, the body contains a large number of bacteria, viruses, when sucking blood on the surface of the human body, these bacteria and viruses will enter the human body through mosquitoes.

After the mosquito sucks blood, it will also produce red bumps on the **, which makes the ** itchy and unbearable. It can also hinder people's rest, interfere with normal life, and affect the quality of sleep.

1. In winter, mosquitoes will find a warm place to hibernate without wind, but a large number of mosquitoes will freeze to death. Mosquitoes also lay their eggs in water for overwintering and then hatch when the temperature warms up. Mosquitoes stop eating when they overwinter, and they behave slowly, so it's possible that mosquitoes won't hibernate if they stay indoors in a warm room.

2. Breed in water, and different types of mosquitoes breed in different water quality and stagnant water types.

3. Mosquito infesting time, mosquitoes begin to appear in April every year and reach the peak of activity in mid to late August. In autumn, when the climate gets colder and the temperature drops below l0, mosquitoes stop breeding and go into hibernation without eating.

4. The life of a mosquito goes through four stages: egg, larvae, pupa and adult. Adult mosquitoes live on land, and mosquito eggs, larvae, and pupae live in water.

5. In the warm season, the eggs can hatch into very small microorganisms and protists that grow in the water in about 3 days and begin to grow in the water; After molting, they finally stop eating, reduce their activity and become pupae; After about two or three days, the pupae come to the surface of the water to shed their skin and emerge as adults (i.e. mosquitoes).

6. Blood-sucking habits, mosquitoes are divided into male and female, only female mosquitoes suck blood, and males do not suck blood. Female mosquitoes must suck blood from their ovaries in order to develop, reproduce and judge offspring. Mosquitoes also transmit diseases by sucking blood.

7. Habitat habits, mosquitoes like to inhabit in hidden, dark and poorly ventilated places, such as under the bed, behind the cabinet, behind the door, the wall crack is greatly changed, and the barn, basement, etc.

8. Mosquitoes also have the biological characteristics of being sensitive to carbon dioxide, phototaxis, following air currents, and prefers to gather.

Mosquitoes can survive the winter by reducing their activities or eggs, it will hide in a warm, sunny and leeward place before the winter comes, and stop activities and eating, so as to resist the extreme climate of winter, and a small number of mosquitoes lay their eggs in water for wintering, and the reason why mosquitoes suck blood is to reproduce, pay attention to mosquitoes when they suck blood, it is easy to spread diseases.

Mosquitoes can survive the extreme winter weather by reducing their activity or by using eggs, which can be found in a warm, sunny and leeward place to hide and stop moving and eating before winter comes, while some mosquitoes lay their eggs in water for the winter.

The reason why mosquitoes suck blood is to reproduce, female mosquitoes can only develop ovaries after sucking the blood of humans or animals, so as to lay eggs and reproduce, and female mosquitoes mostly start to suck blood after two to three days of emergence, and the temperature is above ten degrees, pay attention to male mosquitoes do not suck blood, only suck plant juice and nectar.

Mosquitoes like to live in dark and damp places, the body contains a large number of bacteria and germs, when it sucks blood, bacteria and germs will enter the body of people or animals through the mouthparts of mosquitoes, thus spreading diseases, and after being bitten by mosquitoes, there will be red bumps, itching or pain, etc., affecting people's normal life and sleep quality.

In winter, mosquitoes come in through the windows. Mosquitoes are insects that prefer warm places and usually survive when they are above 2, while in winter the outdoor temperature is relatively low and the house is warmer, and mosquitoes will fly into the house from outside the window. Mosquitoes usually hide around radiators, behind closets or heating lines, etc., which can not only avoid the harsh winter, but also reduce the rate of metabolism and prevent death from starvation.

Mosquitoes (Arthropoda, Insecta, Diptera mosquitoes):

Mosquitoes belong to the order Diptera, the mosquito family, also known as "mosquitoes", and are the most important group of medical insects. Mosquitoes are small insects, the adult mosquito body is about long, gray-brown, tan or black, divided into three parts: head, thorax and abdomen. Mosquitoes are widely distributed and have many species, and so far there have been 3 subfamilies (Macropheles subfamily, Anopheles subfamily, Culex subfamily), 35 genera, and more than 3,600 species and subspecies of mosquitoes recorded in the world.

More than 370 species have been discovered in China, of which more than half are mosquito species of the three genera Anopheles, Culex mosquitoes and Aedes mosquitoes.
