About this in a selection about cockroaches ...

1. Cockroaches are harsh "survivors". These insects are able to continue to live quietly even after having lost their heads. The thing is that, in fact, a cockroach needs a head in order to eat and drink. Therefore, without receiving nutrients within two weeks, he will most likely die. But cockroaches are quite capable of breathing through holes in their bodies. In addition to the fact that the body of cockroaches can live without a head, the head itself is also capable of supporting life for about two more hours. This is evidenced by the moving whiskers of insects.

2. Cockroaches hate being touched. Whether human or otherwise, cockroaches will do their best to run away as soon as possible and not cross paths with people or other creatures that are larger than themselves. As for a person specifically, the contact of a cockroach with oils that one way or another settle on human skin can lead to disastrous consequences. The cockroach's antennae, which he needs for an acute sense of smell and search for a partner, may suffer from this.

3. Cockroaches love our ears. The human ear is a narrow, dark, and warm place, the perfect home for an insect! In addition, earwax releases fatty acids. Similar substances secrete bread and cheese. Who would turn down a house with free food? So the cockroach would not refuse. But, unfortunately, often such an attempt turns out to be deplorable not only for a cockroach but also for a person. Trying to get an insect out of the ear, a person can crush or kill him, and a cockroach crushed inside the ear is an even bigger problem because. it carries dangerous bacteria that can cause serious health problems.

4. When there are too many cockroaches in the room and the struggle for food becomes more and more difficult for them, these insects are capable of desperate acts, namely, biting a person. Usually, they try to avoid people and run as soon as they find them in sight, but if a person is sleeping and does not actively move, a cockroach can find food particles on it and try to eat them, thereby biting a person.

5. Cockroaches love sweets. Pieces of sugar or drops of sweet juice on the table are a paradise for these pests. So it was before. And now, cockroaches avoid sweet food, as it is poison for them. The experiment showed that a cockroach that has eaten sugar suddenly dies. This experience was passed on to insects through generations, and even replacing glucose with fructose, alas, did not help. These insects are incredibly adaptable to any conditions, and therefore understanding that sugar is a poison, it was not difficult for them and did not take much time.

6. Termites belong to the species of cockroaches. Initially, such information was not confirmed by scientists and termites wanted to be attributed to a separate species of insects. But in 2018, the Entomological Society finally caved in and allowed termites to be introduced to the species of cockroaches. Despite this, you should not consider termites unequivocally cockroaches or vice versa.

7. Running away from danger, cockroaches are able to "switch gears". Scientists managed to notice that as soon as the Takara sees a creature larger than itself and tries to run away, its usual run changes to metachronous, that is, faster, when all legs leave the ground in this order: front, middle, and back.

8. Scientists are conducting research on the use of the brain of cockroaches for the treatment of serious diseases. They made sure that cockroaches that live in sewer pipes and polluted water survive calmly and do not suffer any damage. This led them to think about studying their brains, and indeed, chemicals were found there that could deactivate deadly bacteria. In the future, this information may become a breakthrough in the field of medicine!

9. These insects are smarter than they might seem at first glance. Belgian doctor José Halla managed to prove that cockroaches can think by placing houses in front of them with different capacities for the total number of cockroaches. And what do you think? If the house contained 25 cockroaches, then 50 cockroaches were divided into two equal groups and lived in separate houses, and if they were given one house for 50 cockroaches and two small ones, then division did not occur and all 50 cockroaches were determined in a large house. Here is such a collective mind!

10. Cockroaches directly affect the normal functioning of the ecosystem. No matter how useless we consider cockroaches, their contribution to nature is actually quite large. If cockroaches disappear, birds and rats will not be able to eat them, which will lead to a decrease in their population throughout the world. Yes, these animals, of course, will not completely disappear, as they can eat grass, caterpillars, and other insects. What can not be said about some species of wasps that would most likely become extinct if cockroaches died out? In addition, cockroaches enrich the earth with nitrogen, which has a beneficial effect on the growth and development of plants, and if they are gone, then the decrease in plants will again lead to a decrease in the population of those animals that feed on them. Therefore, we just need to put up with cockroaches!
