Unexpected things and benefits of cockroaches

Surely most of us hate cockroaches and find ways to destroy them in any way. But few people know that in some respects, this ugly, foul-smelling animal has certain benefits, even affecting the earth's ecosystem.

Let's review some of their benefits through the article below.

From the super abilities no animal can .

For hundreds of millions of years, cockroaches have hardly changed.

It is said that cockroaches can survive the nuclear disaster. This may not be accurate, but there is a fact that it is possible to call 'Superman' cockroach in the insect world.

The reason is because cockroaches exist on Earth from hundreds of millions of years ago . They even appear before dinosaurs and even when the dinosaurs become extinct, the species still lives "multiply", with little change to this day.

Second , cockroaches possess many possibilities that even the best athletes cannot do. Cockroaches can hold their breath underwater for 40 minutes without any harm.

Cockroaches run at a speed of 5km / h, which means that every second they travel about 50 times the length of the body. If the size is equal to that of a human, the speed of the cockroach is about 700km / h, 5 times more than the jaguar.

Cockroaches also have a special ability to balance well , every second they can change direction 25 times while running. In an experiment in 2002, people put a tiny cannon on the back of the cockroach. When they ran, the cannon was deflected to one side but almost immediately, the cockroach regained its balance and kept the heavy weight on its back.

Third , cockroaches can be considered "immortal" insects . You will not be able to imagine the amazing survivability of this species. Cockroaches not only have a brain, they also have nerve nodes distributed throughout the body to help react to extremely sensitive enemies.

Nerves also help them survive even when there is no head. According to scientists, it is estimated that cockroaches can live for 30 days despite losing their heads and can stop drinking for 2 weeks. The reason is because cockroaches do not breathe with their heads, their blood does not perform oxygen circulation, so they die only due to starvation or infection.

In addition, female cockroaches only need to mate once to be able to conceive for a lifetime, laying over 300 cockroaches. That's why you should never think of this creature being extinct.

If cockroach information is almost immortal that makes you nervous, do you know that, in certain respects, cockroaches also bring significant benefits to human life.

What would life be like without cockroaches?

For ecosystems, cockroaches are an indispensable link. According to Professor Srini Kambhampati, head of the Department of Biology at the University of Texas, cockroaches almost exclusively eat decaying organic matter, which contains a lot of nitrogen.

This substance then passes the cockroach into the soil, providing a rich source of nutrients to serve the growth of plants. With such importance, it can be said that if there are no cockroaches, primeval forests, tropical forests have died since millions of years ago. In other words, the extinction of Cockroaches can cause major disasters for forests and forest-dependent organisms, including humans. Without the forest, we will be seriously deprived of oxygen, often flooded, no wood to produce, no plants to make medicine, no fruit to eat, no vegetables to prevent constipation, There is no paper set for writing, no ginseng for thousands of years, no Mai trees for Tet and in the past there will be no Apples for Newton to discover the theory of Great Things .

In addition, cockroaches are also food of organisms in the food chain of ecosystems such as birds, mice. Hornets also lay parasitic eggs on cockroaches. Thus, if this hateful insect disappears, the effects on the organism are generally very significant.

For people, few people know that, since ancient times, there are many people who appreciate cockroaches. Greek pharmacist - Pedanius Dioscorides (1st century) even encourages the use of cockroaches as medicine by mixing them with oil or boiled. In the 1870s, even Orlean people drank tea with "boiled" cockroaches inside.

Cockroach insects (stalks) together with other insects are thought to help repel famine.

The accuracy of those historical documents probably still needs serious verifications. But one thing is certain, from a social perspective, many poor people are eating cockroaches and insects in general as a way to survive, to cope with global poverty.

Finally, in terms of health, cockroaches are the subject of many medical scientific studies . Live in dirty environments, many bacteria but cockroaches are very healthy. Their bodies contain ' super antibiotic ' compounds, destroying most common viruses and bacteria.

According to a study by Nottingham University (UK), expert Simon Lee announced that in this insect there is a compound that can kill 90% of E. coli bacteria . So, studying cockroaches can pave the way for people to produce an antibiotic super antibiotic , which is resistant to many common diseases today.

Interim: We know that cockroaches are an insect that can carry disease to humans. However, before you intend to kill them, take some time to think about these things and know, it will change your actions.
