Where do mosquitoes go in winter?

In winter, in places where winters are cold enough, you will not see mosquitoes, but they continue to live. Only they live in other forms in which we may not recognize the flying and buzzing insect known to us. Mosquitoes spend the first part of their lives in water and the rest on land and in the air. Their life begins at the moment when the female lays her eggs in a reservoir of stagnant water. Soon, larvae hatch from them, which immediately begin to swim and look for food. Soon the larvae turn into pupae, the pupae, in turn, become adult insects and fly away.

The entire journey from egg to adult takes only nine to fourteen days! But when the winter cold sets in, the eggs and larvae "fall into hibernation." Nothing comes out of them. And females of some species of mosquitoes also fall into a kind of hibernation for the winter. Thus, eggs, larvae, pupae, and adult insects wait out the winter.

An interesting fact is that, although a hot climate is most favorable for these insects, and especially the subtropics, where mosquitoes are a real disaster, they are even more of a disaster in the northern regions of Canada, Alaska and Siberia. This is due to the ability of mosquito eggs to survive the winter in the snow. When the snow melts, the insects begin to hatch in such numbers that cases are told when a person went crazy, bitten by a midge!

Of course, the danger that mosquitoes pose to humans is not only that they bite painfully, but even more so that they transfer diseases from sick people to healthy people. The mosquito sucks out disease-causing microbes along with the blood of a sick person. Then, when a mosquito bites a healthy person, it introduces germs into the body along with its saliva. The mosquito does not need these microbes: what it needs is blood.

Random interesting fact from the Great Encyclopedia:

What were the first vehicles?

If you find yourself on a desert island and you need to drag something from one place to another, what are you going to do? drag! In ancient times, human muscles were the only means of transportation. Man himself was his own "pack animal". But over time, he tamed the animals, taught them to carry riders and loads.

Bulls, donkeys, buffaloes, horses, camels were used by ancient man in various parts of the world for transportation. This suited man for thousands of years, and then he wanted to find a way so that animals could carry more cargo.

Sledges and carts were invented to harness animals. Sledges and sledges with runners ran well in the snow, but were completely unsuitable on the ground.

Man invented the rolling cart. They consisted of pieces of logs instead of wheels placed under a cart or platform. When the cart was pulled, the logs rolled under it. This made the job easier than simply dragging the platform along the ground. She rolled over the logs, leaving them behind her. These logs were collected and placed again in front of the front end of the platform. And everything repeated again.

One day someone thought of cutting a log and making a hole in its center. This is how the wheel appeared - one of the greatest inventions of man. Then two wheels were connected with an axle, and the axle was attached to the platform. A rough cart appeared. Massive wooden wheels were heavy and clumsy, and they wore out quickly.

For thousands of years, man has perfected the wheel. By constructing it from separate hubs, bushings, rims and spokes, he was able to make it lighter and more efficient. Man made rims and tires out of copper or iron so that they could last longer. Finally learned how to make rubber tires.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The level of mercury will show the mobile phone 19.02.2013

Chemists from the University of Burgos (Spain) have developed a technology that allows using a mobile phone to detect and assess the level of environmental pollution with the most dangerous toxic metal.

Scientists have made a special membrane plate based on the fluorescent organic compound rhodamine. This substance does not dissolve in water, but the scientists managed to turn it into a hydrophilic polymer that absorbs water and turns red when in contact with mercury. Thanks to the modified rhodamine, the fact of mercury contamination can be seen with the naked eye. Moreover, when photographing the membrane with a mobile phone, the mercury concentration can be accurately determined. Thus, scientists managed to create a simple and reliable way to identify toxic material.

The importance of this development cannot be overestimated. Mercury is a problem that particularly affects developing countries. Toxic metal released into the environment by industrial enterprises, especially mining, accumulates in the brain, kidneys and causes severe neurological diseases. At the same time, mercury pollution is on the rise. In particular, in the world's oceans over the past century, the concentration of mercury has increased by 25%.

An important feature of the invention of Spanish scientists is the ability to fine-tune the mercury "litmus test". The rhodamine strip can be made to respond to a specific concentration of mercury, such as a sanitary one. At lower concentrations, the strip will not change its color.
