Cockroaches are one of the oldest insects on the planet. Along with other insects, cockroaches originated in the Devonian and lived in caves for scavengers. It can withstand the test of extreme heat and cold, and its distribution is still quite widespread.

But there are some differences in eating habits among different kinds of cockroaches.

How long can a cockroach live?

The life span of cockroach adults is also longer, the shortest of Blattella germanica is about 100 days, and the longest life span of Periplaneta Americana can survive as long as 1 year, and the life span also varies with species and environmental conditions. In the case of Blattella germanica with the shortest cycle, it generally takes more than 2 months to complete a generation, and the longest Periplaneta Americana takes more than one year. The length of life history varies not only with species, but also with different temperature, nutrition and other conditions. A fertilized female cockroach produces a large number of egg sheaths in its lifetime, and Periplaneta Americana can produce more than 50 eggs at most, so the cockroach has a strong fecundity.

Why are cockroaches called Xiaoqiang?

1. Cockroaches have a history of hundreds of millions of years, while people have only a few million years.

2. There are more than 3700 species of cockroaches, omnivorous? NO! As long as it is organic, almost eat it.

3. Cockroaches can survive for at least 10 minutes in a vacuum (non-absolute vacuum, such as the universe).

4. Cockroaches can live under 40 kilowatts of X-rays, while humans? In seconds, cockroaches will die under an X-ray of 10000 electron volts provided by a synchrotron, which is 1000 times stronger than before.

Cockroaches can live in 12 moles of hydrochloric acid and 18 moles of sodium hydroxide for 30 seconds.

6. Cockroaches can live for at least 30 minutes underwater.

7. Cockroaches can live a long time in a 100-degree stove.

8. It takes 29.4 newtons to kill cockroaches, that is, slippers, with traditional weapons.

9. Cockroaches climb slightly slower than people run, but this does not include the speed of climbing on vertical walls. Cockroaches are flat on the ground in the water, and cockroaches even have wings to fly.

10. After the cockroach's head is broken, the body and head can still live for 9 days respectively, and the cause of death is excessive hunger.

11. Some biologists have come to a conclusion according to the ecological habits of cockroaches. If one day there is a global nuclear war on the earth, all living things in the affected area, including humans and even fish, will disappear, and only cockroaches will continue their lives. This is because usually the human body can tolerate a radiation dose of 5rems (units of radiation). Once the total amount of radiation exceeds 800rems, it will definitely die. While Blattella germanica can tolerate 9000 to 105000rems, Periplaneta Americana can reach 967500rems! So even if there is a nuclear explosion, cockroaches can survive.
