Would the world be better without mosquitoes?

Microbiologist Ronald Ross has discovered a @致命疟原虫的蚊子 with @.

No. I know that ** has been introduced in previous issues. Take a moment.

Not because it will disrupt the food chain.

The mass extinction of mosquitoes will lead to the disappearance of about 3,500 species, and this is only the number of mosquito populations currently recognized on Earth. Mosquitoes have been living on Earth for hundreds of millions of years and becomeFood chainan important part of the .

It turns out that even if scientists can find a way to eradicate mosquitoes completely, it will lead to serious ecological problems. In the case of the Arctic tundra, for example, there are several species of mosquitoes that are extremely abundant as food for migratory birds. Once these mosquitoes become extinct, the number of birds in the area could be reduced by more than half.

Mosquito repellent method:

1. Use mosquito nets or screens to isolate mosquitoes, mosquito nets can not only avoid mosquitoes but also prevent wind, and can also absorb falling dust, especially suitable for children. Screens allow fresh air to enter the room while allowing harmful fumes to flow outside.

2. Place a few boxes of cool oil and wind oil essence in the bedroom.

Or put a pot or two of blooming evening primrose.

Jasmine, Milan, mint or rose, among others, mosquitoes will avoid them because they can't stand their smell.

3. Indoor installation is orange.

Light bulbs, or light translucent orange-red cellophane are placed on the bulb, and mosquitoes will flee in fear of the orange light when the light is turned on.

4. Use an empty wine bottle or cup to fill it with sugar water or beer and put it in a dark place, so that mosquitoes can smell the sweet wine.

The flavor will drill into the bottle, and it will stick to the sugar water or beer to death.

5. Eat raw garlic and oral vitamin B

Excreted from the body through human physiological metabolism, it produces a smell that mosquitoes dare not approach.

If there are no mosquitoes in the world, the food chain collapses, and there are no dragonflies, because dragonfly larvae eat mosquito larvae, so without mosquitoes, there are no dragonflies, and by extension, there are more advanced animals.

The absence of mosquitoes in the world will have a certain impact in the short term.

From the perspective of the biological chain, the mosquito as the bottom species, geckos and other higher species with it as the object of predation, the disappearance of the mosquito will inevitably bring certain disasters to the species in the upper layer of the food chain, affecting the upper species to obtain food, and the competition between the races with mosquitoes as the predator is intensified, forcing the upper species to stabilize their own development by maintaining a certain number of relationships, and maintain relative stability in the later stage.

For us humans, the impact is not large, and even brings great benefits for a certain period of time: reducing the spread of diseases brought by mosquitoes and the gray shades brought by mosquito bites. This is related to our special role in the food chain, some people say that people are at the top of the food chain, in fact, in my opinion, the position of people is very important, independent of the ecological chain and only relying on the ecological chain, is the transformer and balancer of nature.

For mosquitoes, cockroaches, locusts and other pests, in fact, it is just a definition given by human beings (biased towards the stability of human life), every life, there is no harm or benefit, they are all part of nature, and they are one miracle after another created by the evolution and development of species. From this point of view, we human beings have to pay supreme respect to these living beings.

A: There is a saying that "to exist is to be reasonable." If there were no mosquitoes in the world, there would be another alternative animal because the environment required it. Mosquitoes play an important role in nature

1. As a natural filter, mosquitoes are of great significance to the environment. Mosquito larvae grow in the water and feed on detritus, which float and clog the surface of the water, while mosquito larvae prevent debris from clogging the surface of the water and the plants in the water do not die due to lack of nitrogen and oxygen.

2. Male mosquitoes do not feed on blood. Instead, he survives on the sugars present in the nectar of the plant. When male mosquitoes feed, they help pollinate plants of the same kind.

3. Mosquitoes are food for migratory animals and birds**. When birds migrate north during the summer months, they rely on large numbers of mosquitoes for food. Without mosquitoes, the migration process is difficult to complete, and the number of birds that survive the migration declines dramatically.

Summer mosquitoes are indeed very, very annoying, biting on the body will not only have a big bag, but also itchy and unbearable, biting too much is worse than death.

As annoying as mosquitoes are, they are an important part of nature's food chain, and they are a fundamental part of it. Many animals feed on mosquitoes, such as dragonflies, spiders, and even frogs. If there were no mosquitoes in nature, many animals would lose important food**, and many animals would disappear as a result, affecting the balance of the entire food chain.

Although mosquitoes are annoying, they exist for a reason.

All living things on the earth are interdependent, if a certain species becomes extinct, then it is possible that the ecology of the earth will be out of balance, and the first to be harmed may be the organisms that have a food chain with mosquitoes, but with the development of events, human beings may also be threatened.

So in addition to the above-mentioned disadvantages, are mosquitoes not beneficial? The answer can be found in the mouths of scientists. According to scientists, mosquitoes are divided into males and females, and the mosquitoes that bite people are actually female mosquitoes because they need the body's blood to replenish the body's energy to give birth.

Male mosquitoes generally do not bite, and at night male mosquitoes can also spread pollen to certain plants for the purpose of pollinating plants.

If mosquitoes do become extinct, then these plants that rely on mosquitoes for pollination will face extinction, and the animals that need them to provide the food chain will be affected. There are also some small animals, such as small geckos and frogs, which eat mosquitoes and other flying insects as their main food. If mosquitoes become extinct, although these animals can still eat other small animals, because there are fewer edible species, it will inevitably have a certain impact on their survival.

In this way, the presence of mosquitoes still has a certain value.

Mosquitoes are one of the creatures that humans don't like, if there are no mosquitoes, human beings will be very comfortable in summer, will not be bitten by mosquitoes, for humans it is hoped that mosquitoes will disappear, but S mosquitoes are also indispensable in the biological chain, with the disappearance of mosquitoes, some animals that feed on mosquitoes will also disappear, the world will be out of balance, and it is also a great threat to humans.

If there are no mosquitoes left in the world, the ecological chain will collapse.

Without mosquitoes, there would be no more of their larvae, and the entire biological chain would be destroyed. Small animals that feed on mosquitoes and mosquito larvae, such as dragonflies, bats, swallows, and tadpoles, will starve or even starve to death because they lack enough food.

The lack of food will cause them to lose their desire to reproduce offspring, and those animals that feed on these animals will also lose their food**......Finally, it may cause an imbalance or even collapse of the entire biological chain.

In addition, the larvae of mosquitoes live mainly in water. Their food is the remains of some plankton and microorganisms and even plants and animals, which will decompose the remains of animals and plants, allowing those substances to return to nature, and promoting the overall cycle of nature.

Do all mosquitoes suck blood?

Not all mosquitoes suck blood and bite people. First of all, male mosquitoes are vegetarian, and female mosquitoes will only suck blood after pregnancy in order to increase nutrition for the baby. But this is also a last resort, the female mosquito only to suck blood and obtain a protein in the blood, in order to promote their ovaries to mature, so as to successfully give birth to the next generation.

Usually, they are also vegetarian. They can also help plants pollinate while sucking the nectar of plants.

Summary. 1.If there were no mosquitoes, Henry II's army attacking Italy would not have been disintegrated by malaria, dengue fever, which infected tens of thousands of people, would not have been epidemic, and the amber mosquito that sucked the blood of dinosaurs in "Jurassic Park" would have been changed to amber fleas by the screenwriter.

1.If there were no mosquitoes, Henry II's army attacking Italy would not have been disintegrated by malaria, the Dengjiao fever that caused tens of thousands of infections would not have been prevalent, and the amber mosquito that sucked the blood of dinosaurs in "Jurassic Park" would have been changed to amber fleas by the screenwriter.

2.Humans can safely and boldly expose their skin on summer nights. The dark environment, carbon dioxide and the chemicals in sweat all have a strong attraction to mosquitoes, and once the mosquitoes are gone, we don't have to worry about the consequences of summer night sports and black clothing.

3.If the mosquitoes disappear, more people will live longer, the population will increase, and more money will be invested in education and the public domain, and the development of southern Africa will be faster and faster.

4.The huge mosquito repellent and mosquito control industry will suffer. Youcong chain health insecticide, which reached an output value of 7.5 billion yuan in China in 2007, will completely disappear.

The mosquito coils, wind oil essence and flower water that are essential for every family will also be completely abandoned by human beings. In the near future, they may become a kind of perfume, labeled as "the smell of the mosquito era" and sold as a luxury item.

5.The disappearance of mosquitoes will have a different impact. The reindeer herds in the Arctic valley often deliberately choose windward routes to avoid mosquitoes.

If the hum is gone, the deer herd may change its route, and the crops and soil along the way, including the cleanliness of the ground, will be greatly affected.

6.The presence of mosquitoes is sometimes constructive, for example, in some tropical areas, mosquitoes are also one of the insects that spread the cacao flower powder. Without mosquitoes, cocoa trees will be less productive, and people won't have as many "milky, silky" pre-coincidence oaks as they can eat potatoes.

Mosquitoes are easy to catch and eat pretty good. Richard Merritt, an aquatic entomologist at Michigan State University, said. Without mosquito larvae, hundreds of species of fish would have had to change their diets to survive.

It sounds simple, but eating habits are deeply imprinted in the genes of these fish. Harrison said. For example, the mosquito-eating fish (gambusia affinis) is a specialized mosquito predator that is very good at killing mosquitoes, so it is farmed in rice paddies and swimming pools as a means of pest control, without which they may become extinct.

And the disappearance of this or other fish can have a huge impact on the entire food chain, up and downstream.

In addition, many species of insects, spiders, salamanders, lizards and frogs also lose this important food**. In a study published in 2010, researchers sprayed a park in the Camargue region of France with microbial pesticides and tracked the survival of insects that preyed on the hairy-footed swallow. They found that each nest produced an average of two chicks after microbial insecticide spraying, while an average of three chicks hatched at other control sites.

Birds that prey on mosquitoes in large numbers are likely to turn to other insects that will multiply in large numbers in the "post-mosquito era" to replace the mosquito niche. Other insectivorous plants and animals may not think of them at all: bats prey mainly on moths, and mosquitoes make up less than 2% of their stomachs.

If you're consuming energy," asked Janet McCallister, a medical entomologist at the U.S. Centers for Disease Control and Prevention, "would you choose a 22-ounce moth steak or a 6-ounce mosquito burger?" ”

The selection on the menu is plentiful, and it seems that most insect predators wouldn't starve in a world without mosquitoes. It seems that the impact of mosquitoes on ecosystems is not so great that people will give up on the idea of killing them for a while.

If there are no mosquitoes in this world, many kinds of creatures will be lost, and according to incomplete statistics, if one creature disappears on the earth, it will affect the survival of nearly 30 kinds of creatures.

That means the surroundings are very clean. That is, if the surroundings are exceptionally clean. Then there will be no mosquitoes at all. But I think it's actually a good thing to have no words!

If there are no mosquitoes in this world, there should be no problem, because after all, some other animals do not generally use words as poems, but words will suck human blood, so I think this should be very happy if there are no mosquitoes.

What if there were no mosquitoes in this world? If there are no mosquitoes, it will be good wow, a mosquito bite is a big bag, and some of them are very painful. Especially in the countryside, mosquitoes are really a handful, and mosquitoes are also poisonous, if there are no mosquitoes in the original world, it is really very, very much.

A happy thing.
