CATDOLL : CATDOLL: The social value of cockroaches cleaning up garbage (What is the social value of cockroaches cleaning up garbage)

1. Can Fengyoujing repel cockroaches?

Yes, Fengyoujing is effective in repelling cockroaches. Fengyoujing and water sprayed together in the room can alleviate the appearance of cockroaches, but it is only temporary. Once cockroaches smell something like medicine, they will hide far away. After a period of time, the smell of Fengyoujing evaporates, and cockroaches will still be very active. In daily life, we can choose some drugs to remove cockroaches, or clean up cockroaches by cleaning, cleaning up garbage and unwanted items, especially some newspapers or magazines in the home, checking under the furniture, or behind and on the ceiling, or in the hidden places of the wire trough, etc.

2. What is the significance of the existence of cockroaches?

Many people have the impression that cockroaches are terrible bugs, extremely ugly, disgusting, scary, dirty, and can bring diseases, etc. This is no wonder, because most of us can only see a few species of cockroaches in our lifetime, among which German cockroaches are the most common. Because they are the most common, many of us have the same impression of cockroaches as their image. To be honest, the image of German cockroaches is indeed not good. The reason why German cockroaches are the most common is related to their habits.

German cockroaches have several characteristics. First, they are small in size, which makes it easier to hide. Their weight is also smaller, so they can escape faster. Second, they reproduce quickly, and it only takes two months to complete a generation cycle. Third, their body structure is good at climbing various terrains. Because of their super climbing ability, they can move freely in various wall gaps. Fourth, and most importantly, they are afraid of cold, and the houses where humans live can be heated, so German cockroaches like to move around in human houses. Because of this, German cockroaches have evolved the ability to reproduce and survive in human living areas, so their numbers will naturally remain high. As a result, humans frequently come into contact with them, and directly regard these insects with terrible appearance and carrying germs as symbols of cockroaches.

However, although German cockroaches are common in life, they are only one of the more than 4,000 species of cockroaches in the world. On our planet, there are all kinds of cockroaches with very different shapes, and some cockroaches don't look so scary. Many foreigners raise cockroaches, of course not German cockroaches, but some cockroaches with practical value.

Generally speaking, cockroaches have the following uses:

The first use is as a pet. There are hundreds of species of cockroaches sold as pets on the market. Some are even sold at extremely high prices. For example, a cockroach called the Indian question mark is a favorite of players.

For example, the Australian rhinoceros is a kind of cockroach that does not look too scary. It originated from Queensland, Australia. It is relatively large in size. One of its young can cost up to 1.1 million US dollars on the market. Only the rich can afford it.

The second use is for feed. This is a large market, and about dozens of cockroach species are used for feed. The advantages of using cockroaches as feed are: complete nutrition, simple breeding, and gentle personality. The only disadvantage is that they are a little allergenic. The more common cockroaches used as feed are green bananas. Let's take a look at the picture:

There is also cherry red, which can also be used as feed, as shown in the picture:

At present, the market share of cockroach feed is as high as one billion US dollars. Many farmers like to use cockroaches as animal feed, and the response is very good.

The third use is to develop drugs for the benefit of mankind. At present, American cockroaches are maturely used in the development of drugs, and in my country alone, the cumulative output value has reached hundreds of billions of yuan. However, it should also be noted that the claim that cockroaches can treat cancer has not been recognized in the medical community, so don't believe in the so-called cockroach cancer treatment drug.

The fourth use is to participate in the natural ecological chain. There are more than 4,000 species of cockroaches in the world. With so many species, they must have their own unique position and role in the ecological chain. The extinction of a species often causes a series of chain reactions. If they all become extinct, what negative effects will it have on nature is still unknown.

3. What do you think of the cockroach breeding project?

The cockroach market will develop steadily within 10 years.

The prospects for breeding cockroaches are good. In my country, the most common cockroach species that are worth breeding are the American cockroach, the Australian cockroach and the German cockroach. They are distributed in all provinces (autonomous regions and municipalities) in my country, and are especially numerous on rural earthen stoves. They are known among the people as tea-loving lady, fragrant lady and oil-stealing lady.

Cockroaches are a kind of "good medicine for the world". There are special entries on "cockroaches" in pharmacopoeias such as "Famous Doctors' Records", "Tang Materia Medica", "Compendium of Materia Medica" and "Supplement to Compendium of Materia Medica". Modern medical experts believe that cockroaches are cold in nature, salty in taste, and have the effects of dispersing blood stasis and detoxifying. They are clinically used to treat acute gastroenteritis, ascites, infantile malnutrition, sores, swelling and poison, etc. They can be dried and ground into powder for oral administration or decoction, or they can be crushed and applied externally.

Dried cockroaches have long been used in traditional Chinese medicine prescriptions. With the development of medicine, their extracts are being used by more and more medical institutions to develop and make various medicines. At present, the price of dried cockroaches in the medicinal material market has risen from 28 yuan per kilogram to about 100 yuan per kilogram. The protein content in dried cockroaches is 60% to 70%, which is an excellent bait for geckos, frogs, centipedes, pheasants, toads, silver hairtails, etc. It is reported that in recent years, due to the vigorous development of precious aquatic products and rare animal breeding in Malaysia and my country, a large number of cockroaches are needed as bait, so cockroaches are in short supply and the price is high.
