Fill in the blanks The four pests include mosquitoes, rats, and cockroaches, how to fill in?

The four pests generally refer to sparrows, mosquitoes, rats, and cockroaches.

Flies, mosquitoes, rats, cockroaches.

In this way, it can be recalled that in the past 100 years, thousands of small insects and species similar to flies, mosquitoes, cockroaches, and cockroaches have been extinct in the earth's world.

The fact that small animals that look like mice has little impact on the earth's natural world and human beings, and tens of thousands of various kinds of small insects and small animals on the earth have been extinct in the past hundreds of thousands of years, in fact, they have not had any obvious impact on the earth's natural world, nor have they stopped the great progress of human beings from changing from ancient apes to modern humans, right? Therefore, it should be said that if the four evils are really extinct, they will not have much impact on the natural world on the earth, the sun will still rise in the east and set in the west, the four seasons will continue to cycle in spring, summer, autumn and winter, human beings will continue to grow old, sick and die, and human society will continue to develop. And these four small "four evils" will become prehistoric relics, and only biological scientists and archaeologists will sometimes study them.

Lao Tzu, a great philosopher in ancient China, once said: "Heaven and earth are unkind, and all things are used as dogs." (刍 chu, refers to ruminants, e.g

Cows, sheep, and so on), which is roughly what it means. When one understands this principle, one will be open-minded.

If all the four pests are extinct, the consequences will be du

It can be scary. Because this upsets the balance of the ecological chain, DAO will trigger a series of unexpected butterfly responses. Albert Einstein once said that if bees went extinct, humans would not live for more than four years.

The veracity of this view is unknown, because it is only a theoretical point of view and has not been verified, but it is not difficult to speculate that the extinction of species may indeed have catastrophic consequences.

For example, if you add mosquitoes to extinction, first of all, a group of animals that live on mosquitoes will die out, such as geckos, spiders, frogs, dragonflies, due to the decrease in mosquitoes, these mosquito-feeding animals will eat more flies, moths and other creatures, resulting in a large decrease in them. And, What is the reason for the demise of mosquitoes? If it is due to the climate, the large number of insects will gradually disappear.

In the end, the entire food chain will collapse, and the humans at the top of the food chain may not be spared.

Everything in the world is complementary, and the four evils have not been extinct for so many years, so we don't have to figure it out!

Those rat traps, electric mosquito swatters, and mosquito coil manufacturers will all go out of business.

The flies are gone, your world is and corpses! No place **!

Speaking of the four pests, many people will first think of mosquitoes, flies and mice, these three animals can be said to be very annoying to everyone, as for the four pests which are the four pests, the following is a brief introduction for you. The four pests are flies, mosquitoes, mice, and cockroaches, and there were no cockroaches before the four pests, and one of the four pests was sparrows. Then bed bugs replaced sparrows, and then cockroaches replaced bed bugs.

The four pests have been said for a long time, and in the beginning, the four animals of flies, mosquitoes, rats, and sparrows were the four pests, and then the sparrows were replaced by bed bugs. So what are the four evils now? Due to changes in social life, one of the four pests, bed bugs, has been replaced by cockroaches, and now the four pests refer to the four animals of flies, mosquitoes, rats, and cockroaches.

First of all, let's talk about flies, this animal is definitely the most annoying existence for everyone, and it is particularly disturbing in summer. No matter how the members of the four pests change, flies are always one of their members. Flies are at some point more annoying than mosquitoes.

The fly is larger than a mosquito, but it also flies faster than a mosquito and is not easy to kill compared to a mosquito.

The annoying thing about mosquitoes is that they bite people very well, and they come out at night to move, which greatly affects people's sleep. Mosquitoes reproduce very quickly, so the number of mosquitoes that come out is also very large. In summer, where there are more plants, you need to take various protective measures to get a good night's sleep.

The rat is one of the four pests and one of the five poisons, and it is a very cunning animal that is diurnal and nocturnal. The annoying thing about rats is that they like to bite things, not only food, but also household equipment. Because rats like to grind their teeth, people are really annoying, they like to grind their teeth and bite things, not only spoiling food but also spreading diseases.

The cockroach is able to replace sparrows and bed bugs as one of the four pests, so you can imagine what a nasty animal it is. And cockroaches are very tenacious, so there is a saying that "you can't beat Xiaoqiang". Cockroaches have super vitality and adaptability, and they can live for 9 days even if they are decapitated.

This kind of sanitary pest that infringes on thousands of households has always caused a lot of headaches for many people. So how do you get rid of cockroaches most thoroughly? It's important to keep your home dry so that cockroaches don't find your door!

Mosquitoes, flies, bed bugs and rats are known as the "four pests" They are all important parts of the ecosystem, and their eradication will destroy the ecological balance, such as the animals that feed on rats after the elimination of rats may lead to death due to lack of food; It will also destroy the diversity of organisms, each species has its own unique gene pool, and when the species disappears, its gene pool also disappears, so harmful organisms such as the "four pests" should be controlled rather than eliminated

So the answer is: we control them, because they are all important parts of the ecosystem, and their eradication will destroy the ecological balance, for example, after the elimination of rats, animals that feed on rats may die due to lack of food; It will also destroy the diversity of organisms, each species has its own unique gene pool, and when the species disappears, its gene pool also disappears, so harmful organisms such as the "four pests" should be controlled rather than eliminated
