How many live cockroaches? Without food, without water and without a head?

On the amazing survivability of cockroaches, if you believerumors that do not know the boundaries, there are many rumors in the people. They say that these insects are able to live for years, they will not even be killed by strong radiation, and food and water are consumed from some whim only known to them, that is, if necessary, cockroaches can live without eating. Some argue that they do not need a head, they can exist without it.

Radiation is still capable of killing parasites, sinceit affects all living things, without any exceptions, but the dose that can cause critical damage to humans, for the cockroach will be harmless, their threshold is overestimated fifteen times. However, in the truthfulness of the other legends, in particular, in those where it is said about how many live cockroaches, it is necessary to properly understand.

Lifespan of red cockroaches

How many live cockroaches, called in the people"Red" or "prusak", provided that they do not experience food problems, depends largely on the temperature of the air in the place where they have to live. The most optimal is the temperature, which keeps around twenty degrees. Taking into account the larval stage of life, cockroaches are able to live a year in a comfortable environment, leaving behind a decent offspring during their existence.

The lifespan of black cockroaches

This type of parasite is more enduring and prolific,compared with red brethren. Mostly they are planted in garbage dumps and in basements, that is, they terrorize the inhabitants of the lower floors of multi-storey houses more. Many people ask themselves: how many live cockroaches belonging to this species? After all, their getting into the house promises a lot of problems. Black cockroaches, under favorable conditions, can remain alive for two years, bringing a consistently impressive offspring. The female of this parasite lives longer than the male.

How many live cockroaches without food?

To the great disappointment of many people, theseparasites can do without food for a long time: the Prussians live without food for up to forty days, and their black cousins ​​- up to seventy. Such survivability can be explained quite simply: cockroaches are poikilothermic organisms, that is, in simple terms, they are cold-blooded. They do not need to maintain a fixed body temperature, so much of the energy is not wasted, but is stored in the cells of the body.

The metabolic rate of poikilothermstwenty times lower, compared to warm-blooded animals, so it is enough for the cockroach to consume food once, so that the energy received is sufficient for a long period, including several weeks, without feeling hungry. This body device has significant drawbacks. The main source of energy production by cockroaches is external resources, that is, insects can live comfortably only in well-heated places, with a negative temperature, the population of their population decreases significantly.

How many cockroaches live without water?

It would seem that once the parasites are able to existwithout food for many weeks, then the water should not play an important role in their livelihoods. However, this is not quite true. In this case, how many live cockroaches without the use of life-giving liquid? Not more than a week. This is due to the fact that water performs a key function in the life of each creature, because it is an important component of every cell in the body.
Cockroaches can not live long without water,so they choose moist foods as food (for example, waste). Water is necessary for them to carry out the digestion process, as well as for the full functionality of the salivary glands, for the well-coordinated work of the circulatory system.

Excellent thermal conductivity of the liquid inmany people open their eyes to the importance of its role as a regulator of temperature in animal organisms. Thus, from the overheating of parasites rescues the release of water droplets through special openings on the body, and the management of nightlife and a durable chitinous shell that protects the cockroach from liquid loss help to live the insect in conditions of low humidity.

Can a cockroach live without a head?

Each of us ever wondered: how long does a cockroach live without a head, and in general, is it possible? The answer may seem strange, but it is positive. To understand the unusual nature of this phenomenon, it is enough to learn that the life support system of a cockroach is not arranged like a human. If the latter loss of the head promises a huge blood loss, a drop in pressure and a loss of oxygen, then the insect will not have any of the above. The circulatory system of the cockroach is not closed, it is completely devoid of capillaries, so the pressure in it is not of great importance. According to the scientist, who studied the structure of the cockroach's organism, if the head is torn off the insect, the vessels on the neck are sealed with clots of coagulated blood. The circulatory system will resume work.
