Why is it now rare to see what was once common in rural areas?

Rural shells are mainly distributed in rural areasAqua priviesand in the crops, so let's talk about the reasons why the shell is almost extinct from these two environmental aspects. In my hometown in rural Gansu, the shell lang is called "climbing cow", as the name suggests, it is a worm crawling on.

1. Changes in rural toilets and livestock breeding In some rural areas of Gansu, this dry toilet must still exist, but with the "toilet revolution" in the countryside now.

And the renewal of the living environment, which was not previously available in the countryside "toilet cleaner."

It has also entered the toilets of thousands of households, and I am talking about this toilet cleaner, which is fatal to the feces and insects in the feces, but it does make the rural toilets a lot cleaner, at least in the summer when the temperature is high, there is not so much foul smell.

So the same is true for livestock farming, even if you don't use toilet cleaners, then to be honest, there are fewer and fewer livestock in the countryside now, and there is also a fecal shell lang who likes to run around in human dung, and livestock dung and urine don't seem to be very interested.

2. Changes in the management of farming and fertilization Another survival scenario is in the crop field, so of course it is based on the "". The poop shell has a good effect on the looseness of the soil, and earthworms.

The effect is the same, the perennial use of farm fertilizer as the base fertilizer, chemical fertilizers and pesticides are rarely used in the crop field is still more feces and earthworms.

So now in the countryside to grow crops, vegetables and fruits, the first thing is to use mulch, then before laying will also apply base fertilizer and chemical fertilizer, and in the process of crop growth again to apply chemical fertilizer, over time the soil environment on which the shell lang depends for survival has been destroyed, and gradually died, disappeared.

It is common to spray pesticides in the fields where fruits and vegetables are grown, and even herbicides are sprayed every year.

This causes the disappearance of the shell in the surface of the soil.

SummaryThe toilet environment, the overall environment, and the planting and cultivation methods in the countryside have been greatly improved compared with before, and the dung shells have lost the environment they rely on to survive. When I was a child, there were aqua toilets in my home, and there were a lot of shells, but now it is no longer a dry toilet, and there are no shells, which is just a microcosm of the almost disappearance of shells in the countryside.

Because with the changes in society, there are few livestock in the countryside now, so there is not a lot of manure, and there is a lack of food, so there are fewer and fewer of them.

The environment where people in the countryside live is very good, there are many green mountains and rivers around, so there are more green plants, including many animals that feed on these green plants. Some creatures in nature are green in color, such as the shell. The shell lang can be said to be notorious in the countryside, because this insect has a stinky smell, and the food is very annoying and incomprehensible.

In the past, it was common to see the shell lang in the countryside, but now it is rare, some people say that this is because the shell lang has been exported abroad, but it is not necessarily, the most important thing is that the shell lang has no food**. <>

The smell of this creature is really unbearable, and this insect feeds on feces, and its body is very dirty, they will put the animal's feces in a relatively private place, and then slowly eat it, and only after they are full can they have the strength to reproduce. In the past, every household in the countryside could see something, because many rural families would raise some poultry, such as chickens, ducks, geese and pigs, so the fecal shell lang would also follow these smells. <>

But now people's lives are getting better and better, and the economic level is constantly improving, so there are fewer and fewer people raising poultry in rural areas. The shell lang is a part of the human world, but the decrease in the number of feces shell lang is not a bad thing, because the usual food of this insect is very gentle feces, without the existence of the shell lang, it may mean that the environment for people to live is getting better and better. <>

In fact, there are some people in rural areas who will raise some animals, but most of them eat feed bought from outside, and there are some chemicals in these feeds. When these organic chemicals are not digested or absorbed in the animal's body, they will be excreted with the feces, but there are some things that cannot be digested, so the ability of the feces to survive will be reduced, and the number will be less and less.

This kind of thing happens a lot in rural households. In fact, it has something to do with raising some livestock and poultry at home. It is very likely that this creature will smell the droppings of this poultry.

The footprints of this creature are often seen in homes. But with the changes of the times and the increase of people's economic development ability, there are not many people who have this kind of thing at home, and these people have been feeding on animal manure, because of the lack of raw materials, of course, they will not go straight to the house. Dung beetles are not to be underestimated.

It is a natural garbage treatment plant that digests and dissolves manure and also converts manure into organic fertilizer. It seems that the Australian grasslands are plagued by manure. They had to import many dung beetles from abroad to digest these disasters.

Dung, in the savannahs of Africa, in cold Siberia, there are dung beetles pushing huge dung balls and working tirelessly.

We did export a lot of dung beetles to Australia. After learning about the living habits of local dung beetles, some people proposed to introduce foreign "scavengers" to help solve the urgent need. The project was named the Australian Dung Beetle Project.

Australia** urgently turned to our country's promoters for help. In this way, the dung beetle army in my country is on a mighty "expedition for the country", and the dung beetle army injected with fresh blood is not only not picky eaters, but also extremely fast. Decomposed, the environment was purified, and the piles of manure were quickly eliminated.

Because the rural environment and ecology have been destroyed and the sanitary conditions have been improved, such creatures are not found underground.

Because the countryside is particularly clean now, there are no aqua toilets, and more attention is paid to the protection of the environment, so it is rarely seen.

The scientific name of the dung shell lang is dung beetle.

Dung beetles, commonly known as dung shells, dung beetles, and dung beetles, are a paraphyletic group under the general family of Coleoptera Scarabs. The body is black or black-brown, large and medium-sized insects.

Dung beetles can use the phenomenon of moonlight polarization to locate and navigate the Milky Way in space to help feed. There is a certain phototaxis. There are more than 20,000 species of dung beetles in the world, found on any continent except Antarctica.

It feeds mainly on animal feces and likes to roll animal feces into balls.

It is mainly due to the fact that the current ecological environment has caused a certain amount of damage, and there is no suitable environment for the survival of this creature, so this situation will occur.

Nowadays, there are a lot of chemicals in many rural areas, which will lead to a decrease in the number of feces shells.

Because the environment in the countryside has become very good now, there is a special person to clean it every day, and there is no dirty and messy environment at that time.

The scientific name of the shell lang is "molting mantis".

It is commonly known as feces cockroach, dung beetle, etc. The molt is a paraphyletic group of the Coleoptera Scarab family, which can use the phenomenon of moonlight polarization to locate and navigate the Milky Way in space to help feed. Molting mantis has a certain phototaxis.

Molting mantis feed mainly on animal feces and like to roll animal feces into balls.

The molt mantis is very widely distributed and is found in a wide area except the oceans and Antarctica. The most famous molt mantis lives in Egypt and is 1 to centimeter long. The largest mantis in the world is the 10-centimeter-long giant mantis.

The molt mantis is distributed in all provinces and regions of China, especially in Jiangsu, Zhejiang, Yunnan and other places. It is mainly produced in Jiangsu, Zhejiang and Hubei. Fujian, Guangdong, Guangxi and other regions, generally self-produced and sold.

The molting mantis mostly inhabits the grasslands and under the dung heaps of cattle, horses and other domestic animals on the edge of the fields, digging into the soil and living in burrows. After the female lays her eggs, the male and female mantis push the dung to wrap the eggs into pills.

Molting mantis can play a key role in the rapid degradation of substances contained in feces. It has a strong ability to decompose mammalian feces and is known as a "scavenger". At the same time, the molt mantis burrows in the soil, which also loosens the soil.

The scientific name is dung beetle.

The dung shell lang, the scientific name is dung beetle, and it also has many other names, such as pushing pills, black bulls, iron armor generals, night tour generals, cart bugs, and scarab beetles.

Wait. They were burly, like warriors in battle armor, but with a small and disproportionate head. There are nearly 5,000 recorded species of dung beetles in the world, except for the oceans and Antarctica.

Outside, they can push dung balls on any continent.

The reason why the shell lang rolls the dung ball:

1. Food: The feces excreted by cattle and sheep contain a large amount of organic matter, which is just the food of the feces shell. In addition to being full at the time, they were also stored and enjoyed slowly.

At the same time, it can also provide the need for egg laying, so that the small dung beetle larvae can receive sufficient nutrients from the beginning of hatching.

2. Delivery room: After the couple who are in the breeding period push the dung ball into the ground, the female will make one end of the dung ball into a pear shape, and then lay a milky white wheat-like egg on the pear-shaped neck of the dung ball, which is both the delivery room and the nursery room. A female can lay hundreds of eggs, so the couple has to prepare enough dung balls.

3. Courtship: When the female fecal shell lang sees the male fecal shell lang pushing the dung ball, she will show great admiration for him, so the female fecal shell lang will help the male fecal shell lang push the dung ball together, and may eventually reproduce together.

There is no relevant information to confirm how many years the shell lang can live.

As one of the most prevalent dung-eating beetles on the planet, the dung beetle uses its feces as food and nesting materials, and is known as the "scavenger of nature". It not only feeds on dung, but also rolls the dung into balls and stores it in its nests, removing garbage from the ground on a large area for humans, and plays an indispensable role in the ecological chain, especially the pastoral economy of the Mongolian steppe.

The shell can't live for as many years, at most one year. What we have here is, especially on the cotton locust branches, there can be more than a dozen on one branch, and this kind is small. And then there's more on the corn simmer.

It is a pest. We'll strangle it when we see it. I've never heard of how many years the shell lang can live.

China is a country with a very rich biodiversity, with a large variety of insects, including feces. It is estimated that there are about 1,000 species known in China, but there may be many more that have yet to be discovered. It is worth noting that with the continuous development of science and technology and the deepening of biological research, this number may also change.

The dung shell is an insect that is a family in the order Coleoptera and the most diverse family in the world. It is estimated that there are about 30,000 species of shells in the world, of which China is very rich.

According to statistics, nearly 5,000 species have been discovered and described in China, some of which are endemic to China. There are a wide range of species of these shells, distributed in different regions and ecological environments, some live in natural environments such as forests, grasslands, deserts, rivers, etc., and some thrive in urban and artificial environments.

They play an important role in nature, they are soil cleaners and nutrient recyclers, and play an important role in maintaining ecological balance and ecosystem health. At the same time, it is also an important object of entomological research, which is of great value for understanding the evolution, ecology and distribution of insects.

There are about 30,000 different species of insects worldwide, of which about 1 4 are distributed in China. However, due to the complexity and huge number of insect taxonomic studies, it is difficult to determine the exact number of species in China. According to incomplete statistics, there may be more than 3,000 species of shells in Chinese mainland.

This number may be adjusted with the in-depth study of insect taxonomy.

According to incomplete statistics, there are more than 1,000 species of shells known in China. However, the actual number is likely to be even higher because some areas have not yet been fully surveyed and studied. They are insects that are very widespread all over the world, and they play an important role in ecosystems, such as decomposing organic matter and promoting soil fertility.

It is a class of insects that are widely distributed all over the world, and there are many and many kinds of insects. Moreover, there are also a large number of species of shells in China. According to the Institute of Zoology of the Chinese Academy of Sciences, there are 60 known groups and more than 500 genera and species in China, including some endemic species.

However, due to the large amount of time, manpower and material resources required for the study of the species of the Shellfish, and the differences in geographical distribution and ecological environment of many species of the Shellfish, there is no accurate estimate of the exact number of the species in China.
