《Blattella germanica》 is the best friend of mankind ... Ah, right, the opposite is true, human beings are the best friends of Germany.
Home is not in Germany, nor in the north
I don't know since when "Southern Cockroaches" and "Northern Cockroaches" became hot words on the Internet. The American Periplaneta (Periplaneta americana) and similar Australian Periplanets (P. australasiae) and Black-breasted Great Cormorant (P. fuliginosa) have been elected as representatives of the "Southern Cockroach" and the title "Northern Cockroach" has been blocked It is much smaller than the former, and in comparison, there may even be a little adorable German cockroach.
The German cockroach vs. the American cockroach can intuitively appreciate the gap between the two heavyweights.
The American badger is not an American species, the Australian badger is not from Australia, and the German badger has nothing to do with Germany. The former two are brothers out of Africa, and for German beasts, the current general opinion is that they are not non-European, most likely from Southeast Asia. The "Southern Cockroach" and "Northern Cockroach" in the mouth of netizens are actually southern Cockroaches. The true representative of China's northern cockroaches is the humble and low-key Chinese real magpie (Eupolyphaga sinensis, commonly known as the maggot “Mu”), which faces the loess and faces the sky.
So why is German cockroach regarded as "Northern Cockroach"? In fact, the German cockroach is a globally distributed invasive species, and it is dominated by north-west and north-south domination. However, in the south, it is a larger cockroach, American cockroach, and Australian cockroach. Make a deeper impression. When the southerners saw the German cockroach, they would probably think that "the cockroach in my house cannot be so cute" or think that "it is still a child".
Of course, these are not true southern Chinese cockroaches, but invasive species distributed worldwide. Most of the true southern China cockroaches, like other native wild animals, do not want to have a relationship with human beings, adhere to the natural environment that their grandparents depend on for generations, and continue to decline with the advancement of human beings. Some species may be lingering on the brink of extinction, and have even disappeared without any knowledge, just like other invertebrates that are "silent majority".
Eucorydia is a type of cockroach native to southern China that can only be found in suitable wild places. Unlike cockroaches at home, they are active during the day and also like visiting flowers.
Unlike the so-called "southern cockroaches" such as the American cockroach, the German cockroach is actually the only cockroach that is fully adapted to the indoor environment among the nearly 5,000 species of cockroach in the world. Does not fully adapt to the indoor environment, but tends to live around the house (peridomestic). Although entering the house from time to time, the American grandma prefers to be an outdoor party; so in the north, you ca n’t spend the winter in the northern country like a German grandma.
In other words, German cockroaches like cockroaches that run into humans' homes are absolutely alien species in cockroaches. 99% of cockroaches are unwilling to approach humans. It ’s really bad to treat German cockroaches as a representative of cockroaches! Hop! Reason!
Most cockroaches don't stay with you so often.
Although the German cockroach is a representative of "indoor pests" in general, it is not a terrible role. First of all, it has no interest in human beings, it will not suck blood like bed bugs, and it will not damage houses like termites, let alone a powerful vector organism like mosquitoes. Cockroaches of any kind, including the German cockroach, have no reliable documentation of the direct transmission of disease to humans as far as I know. German cockroach's direct impact on human health is caused by allergies, while another indirect effect that cannot be ignored is to assist the spread of drug-resistant bacteria in hospitals, farms and other places. If you see a German cockroach or any other cockroach at home, there is nothing to panic if you are not allergic-but this mostly means that you need to clean up.
The German cockroach is not an "unkillable cockroach", and it is not difficult to control it. In most cases, it is even simple. In terms of personal field control and research experience, compared with other indoor insects, such as bed bugs, the German barberry is almost a little angel. In the early days, people's control methods for indoor cockroaches were mainly spraying insecticides or fumigation. These were not effective methods. They could only kill some individuals, and the rest would soon make a comeback. After the layers of tests, the remaining cockroaches, It is also easy to obtain strong resistance. But since poison baits have been widely used for the control of cockroaches, it has become a small case to wipe out the entire German barberry community. Put poison baits in a small number of places in places where cockroaches often infest, and monitor the range and quantity of their movements with sticky worm boards, and in most cases, they will work quickly.
In fact, cockroaches are not difficult to destroy, mainly because they have not mastered the correct method.
Spray the drug without paying attention, not to kill the cockroaches, but to add a buff to the cockroaches
The poorer the community, the less able it is to pay and manage high-level repairs, cleaning facilities, and the work of pest control professionals, the worse the problem of harmful animals such as cockroaches, bed bugs, and mice. Although poison bait is a very effective means of prevention and control, it also needs to be used correctly and coordinated with sanitary management. On the other hand, there are many good and counterfeit products on the market, causing bad coins to drive out good coins. After all, the problem of harmful animals is essentially a public health and social issue. As entomologists, we can only give scientific and effective control and management solutions, but social problems are beyond my ability.
Hate cockroaches? You are actually raising cockroaches!
It is often felt that cockroaches will take over human heritage after human decline or extinction and become the masters of wasteland. The cockroaches in waste soil series are often metaphors for the decline of human beings. Most of them are fierce enemies such as the mutant cockroaches in the "Radiation" series. Occasionally, they appear in a positive image like in "Robot Wall Power". Life tenaciously clinging to the earth sends warm ridicule to humanity.
Entomologists don't necessarily think so. A researcher who knows flies scoffed at this: "Joke, it must be flies after humans take over the earth."
Martian alien? nonexistent.
German cockroaches that depend on humans for prosperity and cockroach species that partially rely on humans, such as American cockroaches, must have tightened their belts after the death of humans. Not to mention, after the human heating system ceased to work, the German concubine had to return most of its territory to the harsh nature. And if the death of humanity is accompanied by disasters such as nuclear winter, not only the German cockroaches, but also the entire cricket family, which is a typical tropical-subtropical fauna, will be bad.

In fact, think about it carefully. We humans have such a kind of resistance except escape and having children. In the natural world, they are completely harmless to humans and animals, and two fingers are twisted into a meaty animal. As "the immortal horror elite with super vitality", various strange talks such as "a cockroach chopped his head and lived for a month" were also derived, which is actually quite ridiculous.
Note: The cockroach will still die if its head is dropped, but the insect's neck does not have aorta and main trachea, so when only the neck is broken, we can kick our legs for a while longer than we do.
The vitality of cockroaches is nothing more than that.
Where is the vitality of the German cockroach stronger than other animals? Ca n’t isolate the cliff as much as the snow leopard arrogantly against the snow and ice, ca n’t fight the waves of the Yangtze River like Psephurus gladius and the beluga dolphin, cannot cross the ocean storm like the diomedea exulans; even the highly touted reproduction ability Many other animals, such as a large number of miserable fish, are left far behind. However, these seemingly more powerful animals than the German cockroach, one by one, are on the path to endangerment and extinction; the German cockroach, a fragile small insect, is prosperous.
All living things are strong in their environment. The "degree of success" of a creature actually reflects how much of the environment is suitable for them. We humans have destroyed the homes of other creatures, including those we regard as symbols of totems and beauty, and transformed them into a land suitable for the survival of German crickets. There are no natural enemies, no competitors, and winters are as warm as spring. , The kitchen waste is endless, the dark gaps made of civil, masonry and concrete are endless, no down payment is required, and the baggage is checked in (big mistake).
We have constructed a suitable environment for cockroaches. Who should we blame?
Although the cockroaches seem a bit moody, sometimes messy with suspicious liquids, and sometimes fed with foods that are not good for health, the loss of the cockroach population is actually nine cattle and one hair, which is a living sacrifice for the gods . If there is a worshipped deity in Germany, this god must be us humans.
