Why are cockroaches so survivable?

Cockroaches are all old acquaintances for us, because there will always be one or two cockroaches in the kitchen at home, and it is extremely difficult to eliminate them, even if they burst their stomachs and cut off their legs, they can still crawl, why are cockroaches so survivable? His ability to survive is reflected in the fact that it can digest a lot of unimaginable garbage and reproduce so quickly.

After cooking at home, there will always be kitchen garbage, and these kitchen garbage is the favorite of cockroaches, these things are disdainful for kittens and dogs, but cockroaches regard them as the most delicious food, when we find out, she can still run very fast, even if the head is screwed off, she can still be alive, and the reproduction speed is very fast, the ability comes from habit, when you are used to surviving in the dark, you will feel that the darkness is also paradise, just like cockroaches, they have no extra choice, Only survive in the dark.

At home, we found that cockroaches should be disposed of in time, because cockroaches are likely to carry viruses, and it will crawl into our leftovers, which is really disgusting, we can stock up on some pesticides at home, or shoot them directly with the sole plate of their shoes when we find them, this is not harming life, the number of cockroaches is far beyond our imagination, the darker the place, the more exists, so we don't have to have a kind heart, directly get rid of this kitchen trickster, let us eat more assured.

Human beings have existed in the world for hundreds of thousands of years, but the era of science and technology is also a few decades, the same is true of high-rise buildings, a long time ago, many people were not enough to eat and wear, the same is to live in the dark side of society, like cockroaches The vitality is very tenacious, but with the development of the times, China's food problem is no longer a problem, everyone can eat enough, and even extravagance and waste, so the vitality of cockroaches is strong because the environment created them, it can also be said that they adapt to the dark environment.

Because the living environment of cockroaches is relatively harsh. He can eat anything. You can eat the corpses of your companions in harsh living conditions. And it has an extremely high litter rate. Strong incubation capacity.

Because the body structure of the cockroach is relatively special, and the cockroach comes out at night, the food it eats is not specific, and it eats everything, so the body's antibodies are very good.

The body of cockroaches is flat, so it is difficult to shoot to death, but in fact, the survival ability of cockroaches is similar to that of ordinary insects, and we have this understanding because it is very common in our lives, so we know more about cockroaches than other insects.

Because it is Xiaoqiang, Xiaoqiang can't be beaten or stepped on, and its vitality is too vigorous.

Adaptable. Cockroaches can survive for a month without a head until they starve to death, which is a vitality that many animals do not have. As you can imagine, as long as the cockroaches are provided with enough food, then they are basically impossible to die.

In addition, the cockroach is very adaptable, and the cockroach can complete a system upgrade within 5 years, and even the elite can be completely changed. Therefore, no matter what kind of environment they are in, cockroaches will be able to adapt and survive very quickly.

Because cockroaches are omnivorous insects, as long as they are organic food, they can be eaten, and they can maintain their own life by eating food, and the reproduction of cockroaches is very fast.

Because cockroaches will ovulate when they encounter danger, their fertility and reproductive ability are very strong, so their vitality is also particularly tenacious.

Because the reproductive ability of this animal is very strong, and it can adapt to a variety of environments, its vitality is very tenacious.

Because they are omnivorous insects, they eat a wide range of foods, as long as it is organic food, such as wood, clothing, etc., they almost eat it. They can also survive for at least 10 minutes in a vacuum, and some scientists in the UK have also done an experiment: cut off the head of a pregnant female cockroach, but the headless cockroach is still alive, and soon gave birth to several small cockroaches.

Cockroaches also have a good ability to self-organize and repair.

The evolution of cockroaches has adopted an "R-shaped strategy", that is, its population density is very unstable, usually has a high birth rate, and has a strong ability to spread, so as to adapt to the changing habitat and living environment.

This is in contrast to the "k-selective evolutionary strategy" of humans, i.e., their population densities are relatively stable, often around the k-value (environmental carrying capacity). In the evolution of organisms, according to the type of population dynamics, it is basically divided into these two types of adaptation.

Cockroaches are quite adaptable to their environment, and their evolution speed is quite amazing, and it only takes about five years for cockroaches to complete an upgrade, evolution, and even complete genetic change. This also causes traditional cockroach medicine to become less and less effective.

Analysis: There are three conditions that cockroaches must have to survive in order to survive: food, a place to hide, and a source of water.

Therefore, to keep your home free of cockroaches, the most important thing is to do a good job of cleaning in the kitchen and cupboards, sealing the food in bottles and jars so that cockroaches can't find something to eat. In addition, in order not to give cockroaches a place to hide, the kitchen layout should be simple, there should be no dead corners that are difficult to clean, and when the kitchen floor, wall corners and cabinets can be kept clean and dry, the moisture and water sources that cockroaches need are cut off. In such an environment, cockroaches have no conditions to reproduce and survive, and they will naturally decrease.

In the public environment, in addition to good environmental hygiene, it is also necessary to spray chemicals regularly and check regularly, which may reduce the harm caused by cockroaches to humans. In fact, humans have been fighting cockroaches for nearly one or two thousand years, but they have never been eliminated, the main reasons are: first, the survival ability and reproductive ability of cockroaches are too strong; Second, the unsanitary environment of humans has created favorable conditions for cockroaches.

Third, the world has not yet developed a medicine bait to completely eliminate cockroaches.

How many cockroaches are in the EU You can always see swarms of cockroaches partying at night, and the most terrifying thing is that when you are sleeping, he may also creep into your ears, and he also has an indescribable smell, very pungent and artificial. There are about 6,000 species of cockroaches in the world, and most of them are never picky eaters and will remove all edible organic matter. Among them, there are dozens of species of cockroaches that live with humans.

The most common ones around us are the American cockroach and the German cockroach. The American cockroach actually came from Africa, and in the 16th century, they sailed across the ocean to the United States, and then began to spread around the world. In the south of our country, there are mainly American cockroaches, which are relatively large, and they can fly.

In the north, there are mainly German cockroaches, and her body is relatively small. But you may not yet know how tenacious the life force of cockroaches is. First, the hairs on the body of the American cockroach are able to catch subtle air currents and then quickly send signals to the central nervous system, so they have a fast reaction speed, can dodge slippers from humans, and they are also one of the fastest invertebrates ever recorded, and second, the American cockroach, they have a flexible appearance, it can hide in a space less than 1 4 of its own height, and it can withstand pressure up to 900 times its own weight.

In addition, cockroaches are very picky eaters, as long as it is organic, it will eat into its stomach, such as hair, dead skin, paper, and nail covers. Because cockroaches have a special set of digestive enzymes in their stomachs, cockroaches can thrive even in nutrient-deficient environments.

Cockroaches also eat rotten food, and this rotten material also includes the corpses of their companions, which is why we often see a dead cockroach with its body hollowed out, missing arms and legs. They also eat their own excrement and are very picky eaters. Third, some cockroaches can go more than 30 days without eating, can go seven days without drinking water, and can also hold their breath in the water for up to 40 minutes.

Fourth, cockroaches also have a series of resistance measures to insecticides, a resistant cockroach comes into contact with insecticides, the effect of insecticides on him is very small, and cockroaches can tolerate a very large amount of radiation, once a biologist has made a conclusion about the ecological habits of cockroaches. If one day there is a global nuclear war on Earth, all living things will disappear in the area affected by radiation. But only cockroaches can survive.

This is because the radiation dose that humans can normally withstand is five rems, and once the radiation dose exceeds 800 rem, they will die. While German cockroaches can tolerate about 9,000 to 100,000 rems, American cockroaches can tolerate about 960,000 rems. So cockroaches can survive even in very high conditions of radiation dose.

Because the genes of cockroaches are very powerful, cockroaches have interpretation genes, and cockroaches are not picky eaters, so their vitality is particularly tenacious.

I think the main reason is that cockroaches can survive in any environment, and the rate of reproduction is also very strong, and this insect is also an omnivorous insect, as long as the food is rich in organic food, it can survive, no matter what kind of environment.
