What is the value of mosquitoes?

Mosquitoes are also part of the biological food chain, sucking the blood of humans and animals and the sap of plants to provide food for dragonflies and frogs. It exists as an intermediate type in the biological chain. Spreading diseases allows some viruses and bacteria that are particularly dependent on mosquitoes to survive and maintain biodiversity.

Saved many beneficial insects that feed on mosquitoes. Enhance human immunity, in the process of mosquito bites, a small number of germs enter the body, the body's own immune system responds, produces antibodies and produces corresponding memory cells at the same time, so that the human body can respond in time when the next time it receives the same or similar germs, it is likely to save a life.

If mosquito extinction is really good for living things, this outcome may be due to the insignificance of the species and the rapidly changing nature of nature; Or maybe it's because the mosquito-eating species are just using them as a snack. No animal starved because of its disappearance, and it can live well. Elsewhere, mosquitoes do not appear as a necessary link in the biological chain, and they can be simply replaced; In many cases, there will be a competing insect willing to replace the mosquito's niche.

A frog on a diet of 50% mosquitoes and 50% moths would love eating moths if the number of edible moths could be doubled. However, it must be acknowledged that there are times when calculations fail, and the extinction of mosquitoes can lead to the extinction of some predator fish or birds, which can cause a wavy cycle in local ecosystems. What remains unchanged is that mosquitoes don't really control any population, so it's unlikely to see any major outbreaks of dangerous species that are pinned down by this common mosquito colony.

The significance of the existence of mosquitoes is to maintain the balance of the ecological environment.

Although mosquitoes are indeed very annoying, every creature on the earth has its purpose of existence, even mosquitoes are meaningful, and they may not be useful to humans, but for the biosphere, the existence of mosquitoes is very meaningful. Mosquito larvae feed thousands of species of fish in the Earth's water system, as well as many beneficial insects such as dragonflies, geckos, frogs, spiders, etc.

If mosquitoes suddenly disappear one day, like some birds, fish, frogs and other mosquito food animals, they can also go to eat some other insects, without the trouble of mosquito bites to spread diseases, the mammals in the forest will reproduce more smoothly, then the result is a large number of trees are gnawed, resulting in ecological imbalance. In terms of water, if these larvae are not available, then the water quality in nature will also be affected to a certain extent.

Mosquito hazards

1. Disease transmission

Mosquitoes can transmit a variety of diseases, such as malaria transmitted by Anopheles sinensis, Culex tribandifolia and Culex pale mosquitoes transmitting Japanese encephalitis, Aedes aegypti and Aedes albopictus transmitting dengue fever, and Anopheles anthropophile transmitting filariasis, which are extremely harmful to humans.

2. Harassment

Mosquitoes suck blood at night, affecting sleep and hindering people's rest; Some mosquitoes suck blood during the day and interfere with normal work; In tourist attractions can influence the interest of tourists. Therefore, urban mosquito control is not only the need to ensure the health of residents, but also the need to improve the quality of the investment environment, which has indirect economic benefits.

The meaning of the existence of mosquitoes is to feed other organisms, achieve "survival of the fittest" for human beings, and stimulate economic growth.

1. Feed other creatures

As a link in the biological chain of nature, since mosquitoes can exist, they must become food for certain organisms, such as fish, frogs, geckos, lizards, dragonflies, etc., these so-called beneficial insects, as well as many birds, are fed on mosquitoes. Therefore, mosquitoes are an indispensable organism in the biological chain, and they are of great significance to the survival and balance of species throughout nature.

2. Achieve "survival of the fittest" for human beings

For humans, mosquitoes transmit diseases and cause a large number of deaths every year. But in a sense, it's a way to balance human and natural ecology, and it's important to limit overgrowth.

At the same time, because mosquitoes will bring different diseases to different people, people can improve their own immunity and increase the body's specific immunity after suffering from diseases, and then they can be protected from such diseases.

3. Stimulate economic growth

In terms of economic benefits, because of the existence of mosquitoes, people's demand for mosquito repellent products has increased greatly every summer, from the earliest point wormwood, to the later mosquito nets, mosquito coils, mosquito repellent liquid, mosquito repellent lamps ......All kinds of mosquito repellent products emerge in an endless stream, feeding a large number of manufacturers who produce these products, stimulating economic growth, in this sense, the existence of mosquitoes, in fact, gave birth to the birth and development of an industry.

If mosquitoes become extinct one day, the manufacturers of these products will have no choice but to reduce their business and have one less way to make a fortune.

The lifespan of a mosquito

Mosquitoes do not live as long as we think, but they are too short to be true, with an average lifespan of between 3 and 10 days for males and 3 times more for females, between 10 and 30 days. If mosquitoes do not eat anything, they will starve until the end of their life, that is, they will not starve to death, and they can only "die of hunger".

Mosquito larvae feed hundreds of fish species in the Earth's water system**, as well as many insects, such as geckos, frogs, spiders and other beneficial insects.

There are about 3,500 species of mosquitoes in the world, and there are hundreds of species of mosquitoes that bite humans, and they have lived on the earth for about 100 million years. Mosquitoes have been eradicated, and perhaps in the short term, some mosquito-borne diseases have lost their primary vectors, but this does not mean that these diseases will disappear forever. And even if there are no mosquitoes, other species will take their place.

At the same time, some species will become extinct with the disappearance of mosquitoes.

1. Ecological value, any organism has its own unique role in the ecosystem, and cannot be completely replaced by other organisms. All kinds of organisms in nature are constantly evolving, and in this process, every nucleus leaks a living organism is essential. The ecological value of mosquitoes is to spread harmful bacteria, make other organisms sick and die, and achieve a balance of biological populations.

2. An integral part of the food chain, providing food for frogs, bats, etc.

3. Scientists have found that there is an antithrombin in mosquito saliva, and scientists hope to study it for medical use.
