Urgent reminder!
There are a lot of them in the community!
Recently, this dangerous creature has appeared frequently in Xiamen
Can spread tuberculosis and deadly meningitis!
There are communities that have captured nearly 500 animals...
thousand! ten thousand! concentrate! meaning!
Don't touch it! Don't eat!
Especially with children at home...
It's what it is -
"Non! continent! big! snail! cattle! ”
I also thought that the snail was slowly climbing up step by step
"Cute"?
NO！ If told
It's big big invasive harmful species —
Giant African giant snail!!
(Network pictures, text pictures have nothing to do)
oh my god
Is there a bout of nausea and tingling in your scalp?
Small heart "poof, poof"?
True
Xiamen, where rain has recently increased
This giant snail came out in large numbers
Angry brush presence!
Hidden dangers!!!
African snails are frequently found in the community
Children are playing, and some children are roasting and eating
Mr. Lin, who lives in the Mid-Levels Yujing East District, has a large green area in the community. According to Mr. Lin's guidance, the reporter saw many African snails behind shaded walls, stone crevices and broad leaves.
This is relatively small, more rain, at night, the roads in the community, grass is everywhere, if you are not careful, you will step on it. The property staff picks it up every day, but the snail breeds quickly and cannot be picked up. If there is a rotten fruit on the grass, it will not be long before it will be crawling with snails. Mr. Lin said.

Ms. Du is also a resident of the community
Every day after dinner
She would take the kids for a walk around the neighborhood
I have seen children in the neighborhood playing with snails at the foot of the wall many times
Very worried about this:
When I was a child, I also played with snails, but it was completely different from the current snails, I was worried about whether this snail would have parasites, I also saw children burning with lighters, saying that they were roasting snails, if they ate it, would they be poisoned?
Ms. He from the north came to work in Xiamen
Concerns were also expressed:
In the past two years, I don't know what's going on, there are fewer and fewer small snails, more and more large snails, and I don't know if the living space of small snails is occupied by large snails.
As Ms. Du said
There are more and more African snails in the community
Some children don't just touch it with their hands
Also take a lighter...
Lin Ruoxuan (pseudonym), who will be in the fourth grade next year, has liked to raise all kinds of small animals since he was a child. "We have played with this kind of big snail, and many friends will secretly raise it."
Another child, Wang Zhuoyi (pseudonym), went to kindergarten this year, she saw on TV that there were baked snails in France, and found that there were many large snails in the community, so she took her little friend with a lighter to prepare to roast two to taste, "But before it was cooked, the lighter was confiscated by the family." ”
It's frustrating
This african snail has recently emerged
The number is staggering!!
Too much!
There are nearly 500 caught in two or three hours in the community...
According to Yijiayuan Property Mid-Levels Royal Landscape Management Office:
"These snails have been around since May and I've never seen them that much." Property personnel said that after receiving feedback from residents, they first contacted professional agencies, but the weekly removal effect was not good, and the snails were still very active.
At present, only manual capture can be taken, after the sun goes down, arrange three or four cleaning staff and two security guards, flashlights to find snails in the community, but it is still difficult to control the flood of snails.
Property staff used clips to clear snails from heights
Mr. Yang is a cleaner in the community, and every morning, when he cleans, he will find a lot of trampled snail remains on the ground. "During the day, snails like to hide in cool, damp places, especially drainage channels," he said. In the past two years, there have been more large snails, and the small snails do not seem to see it, and they do not know whether they have been eaten by the large snails, after all, the large snails eat everything. ”
According to the security personnel of the community: the best time to catch it is before the rainstorm, a few people can catch nearly 500 in two or three hours, weighing more than a dozen pounds.
Even more frightening
Recent "massive invasion" of African snails
Not just Xiamen
The community in Fuzhou has also appeared!
The Fuzhou woman went home at night to pick it up
Straight exhale has an air cushion as big as BB!
Miss Shi, who lives in the Pearl Community of Jinshan, recently found a huge snail when walking her dog at night in her community...
"This snail is the size of my air cushion BB!" The shell and flesh are dark in color, unlike ordinary snails; the snails I have seen before retract into the shell when they touch it, and they do not indent into the shell when they touch it, and they are not afraid of people at all. This is the biggest snail I've ever seen! ”
How big is it?
Come and feel it
After the discovery of the big snail, Miss Shi checked several times with the Baidu zhitu on her mobile phone, which showed that they were all African large snails, which were extremely destructive to the environment.
Because she did not dare to be 100% sure whether the snail with the egg in her hand was an African snail or not, and whether the release would have an impact on the environment, Miss Shi did not dare to throw it away, took a transparent plastic box and raised it, and fed him a little grape to eat.
Boy
It's delicious to ☟ eat

This egg-sized snail is
African Big Snail!
So huge
An African snail that looks ferocious
You may be curious
What the hell is going on with this cargo!
How destructive is it!
Let's start with a wave of key points:
Invasive harmful species!
Carry pathogenic bacteria on the body
Tuberculosis and meningitis can be transmitted
Teeth are striking, devouring the corpses of companions
Destructive and reproductive ability is extremely strong
……
Unveil this big snail for you
All terrible "secrets"!!
The maximum can be more than 20 cm
Landed from Xiamen in 1931!
African snail
Exactly "What the hell?" ”
According to fruit shell network science:
The African giant snail, also known as the brown cloud agate snail, belongs to the agate snail genus of the agate snail family, and is indeed produced in Africa, or more precisely, East Africa.
The biggest feature of the African giant snail is that it is large, to what extent? The shell length of adult African snails is generally about 7 or 8 cm, and the largest can reach more than 20 cm.
Compare a ruler to a ruler -

Twenty centimeters, what is this concept?
Take a look at this comparison chart!

Let's analyze its shape -
The African giant snail is a terrestrial snail with a slightly spindle-shaped shell, which is more pointed and thinner than the common native snail, but more similar to some field snails. The shell texture of the African large snail is thicker, the thread is generally about six or seven layers, the surface of the shell is white or yellow, and there are tan longitudinal stripes or cloud-like stripes perpendicular to the thread (this is also the origin of the name "brown cloud agate snail").
Not beautiful, but not too ugly either—

If you've eaten snails and you've eaten the African snail, you'll have a vague sense that something is wrong, and the latter is big, but it's not missing —yes, your instincts are correct. Compared with the field snails, the African large snail has one less piece of yǎn, that is, the small piece that covers the shell of the snail.
The shells of African snails are directly opened - when hibernating, or when the climate is too dry, they can only use the secreted white mucus to close the shell mouth, which plays a certain protective role.
And what you would never have guessed
Such a big cargo
Unexpectedly landed from Xiamen!
First of all
The reason why this big snail is there
Photographed outside of Africa
Precisely because
It's a no-brainer
enter! invade! thing! seed!
Today, this large snail is widely distributed in humid and hot regions such as Asia, the Pacific, the Indian Ocean and the Americas.
African large snails feed fiercely, grow rapidly, reproduce quickly, and are extremely harmful to crops.
It is a Class II quarantine pest! Notorious in China, the United States and other countries!
Since landing in Xiamen in 1931, China's Fujian, Taiwan, Guangdong, Guangxi, Yunnan, Hainan and other places have also become their world. They have invaded the provinces of South China and become invasive organisms that seriously endanger the ecology and agricultural cultivation of various places, and the African giant snail can endanger more than 500 crops, and the activity period in Fujian Province is mainly from April to November every year.
In the south of our country, such big guys can now be seen often. Image: akjunshi.com
In Southeast Asia, the African giant snail is a much more discolored pest. Because this terrible invasive species can seriously affect the growth of various tropical plants. Coconuts, cocoa, pineapples, etc., once parasitized by African snails, the damage is almost devastating. In addition, there are rubber trees, which are well known to be very precious natural rubber, and many products in people's lives use this raw material. And the African giant snail is the most terrifying destroyer of the rubber plantation.
That's why
It is also crowned
"The World's Top 100 Invasive Species"
The name of the
Here's the problem:
Why are they so invasive?
Can eat, can be raw, extremely ferocious
Five or six clutches of eggs can be laid a year
All the delicious and unpalatable ones are swept away!
The reason why it became a hundred invasions
Naturally because
They have a strong appetite and amazing reproductive ability!
The African giant snail depends on being able to eat and grow.
African large snails can lay five or six nests of eggs a year, and if they are in good physical condition, they can produce five hundred at a time, and at worst, there will be more than fifty guarantees.
Food includes crops, trees, fruit trees, vegetables, flowers and other plants, trees in the field, delicious and unpalatable, can not eat, all swept away, hungry also eat paper and companion corpses.
Previously
There are also quite a few amazing introductions
They can also eat digestive cement directly?!

It is reported that the African large snail used for breeding, boiling and eating fried and baked can be eaten, many restaurants in the French large snail is actually the meaty African large snail (in fact, it should be used the French large snail Helix pomatia or scattered large snail H. aspersa）。
But this news that sounds like good news is not really good news. Want to rely on foodies to exterminate an invasive species? Too young, too simple. In fact, the invasion of the African giant snail has a lot to do with foodies. It is precisely because of the overestimation of the combat effectiveness of foodies that the African large snail was introduced too much that year for breeding, but on the one hand, the supply was oversupplied, on the other hand, the lack of effective breeding control and environmental isolation, these big guys successfully leapt over the farm, escaped to the natural habitat, and established their own population.

so
The fecundity and destructive power are so amazing!
What exactly is the harm in itself?
Can you touch it? Can I eat it?
What are the adverse effects of an invasion?
It carries pathogens such as blood lines
Can cause tuberculosis and fatal meningitis!
For the African giant snail that appears in the wild
Just one kind word of advice:
Better not to touch it! Don't eat it!
It is reported that:
African large snails are mostly active in humid environments
I like to go out in the rain or at night
Don't eat it!!!
The African giant snail grows in the wild and is an intermediate host for many animal parasites and pathogenic bacteria. Like Fushou snail, it has "Guangdong live blood nematode", which can spread tuberculosis, meningitis, encephalitis, etc., and it is extremely harmful to eat.
By eating African large snails infected with the parasite, or by contact with their excrement, the C. elegans may enter the human body and parasitize in the body's central nervous system or cerebrospinal fluid, potentially causing fatal meningitis. Some people say that when fully cooked, the parasite can be eliminated, but there is still a certain risk.
It's best not to touch it!!!
Some people say that African snails can be used as pets, which is not OK! It may have eggs in its feces or mucus! Contaminated water or vegetables can also spread bloodworms, infecting humans! Be careful, children have low immunity, do not touch African snails out of curiosity!
African large snails have a lot of mucus, including a variety of bacteria, if the public's resistance to bacteria is weak, it is easy to cause allergic reactions, so see these large snails do not touch, especially children. It is recommended that you do not catch African snails in the wild as pets out of curiosity.
Here's a little bit of knowledge -
On some islands in the South Pacific (including the Hawaiian Islands, Micronesia, etc.), African snails built up their invading populations—they were supposed to be stocks of food for U.S. troops during World War II, and then, unsurprisingly, they escaped into their environment. To this end, the U.S. government introduced the meat-eating rose snail (Euglandina rosea), hoping to control these big guys. However, rose snails apparently prefer to eat native native tree snails (Partula spp.), and the African large snail failed to control it, but it took less than a decade to completely exterminate a large number of tree snails — you know, since 1500, a large number of molluscs have indeed gone extinct, and Hawaii's extinct molluscs account for 70% of them, and the rose snail alone has killed a third of them.

So, human beings
Sometimes don't be too clever...
Let's focus on the next one
The situation of the African giant snail in Fujian
In fact
Including Xiamen previously, as well as Fuzhou and Putian
There have been african snail invasions!
In Xiamen
There are many rainy seasons in summer
There are always Xiamen people in the street green belt, community green space
Giant snails were even found in the vegetable garden in the yard
For example, previously reported
A couple walking in the neighborhood
A huge snail appeared
Scared the girlfriend enough
Almost fainted
The first time I saw such a big snail
Netizen @nicole - Zhong Xiaoyi also said
She also found this large snail in Jimei
And in July 2016
Typhoon Nibert came
This is the case at the Xiamen Ferry Terminal
Come and feel the wave
Xiamen netizens
The fear of being dominated by the African giant snail!
In Fuzhou
There have been intrusions before!
Someone found it in the neighborhood
Eggs are so big —
Someone found it in the meadow
Dense Phobia's Feeling -
Putian has also reported!
Look at this style
It's goosebumps —"
African Snail Invasion Case!
This is not them
It's the first time you've got something going on!
1
Florida, USA
On April 15, 2013, Taiwan's Daily News Cloud reported that thousands of rat-like "African giant snails" invaded in Florida, USA. The invasion of African giant snails in Florida began in 1966, when a child brought three snails from Hawaii back to Miami, and within 7 years, they had become a huge population of 17,000. The local government spends millions of dollars a year on snails, but after each rainy season, they grow explosively. A single female snail can lay 1200 eggs a year and eat lime like crazy to replenish calcium and promote the development of the shell. In addition, they transmit murine lung nematode, which has the potential to infect humans and cause a type of meningitis.

<h3>Nanning, Guangxi</h3>
On September 20, 2013, african large snails appeared on the outskirts of Nanning, which are extremely fertile. This "pastoral killer", which was listed as one of the first 16 invasive alien species in China, is extremely harmful to crops such as vegetables and is a class II quarantine pest for The entry and exit of china. The African giant snail is a plant-eating xerophytic snail with strong reproductive ability, and its diet involves hundreds of herbs, woody and vines, which are extremely harmful to flower beds and farmland crops, and are known as "pastoral killers". Although the African giant snail reproduces extremely quickly, it has natural enemies in Guangxi and can be killed with pesticides, so it has not caused a large-scale outbreak.

<h3>Fuzhou, Fujian</h3>
In July 2014, Ms. Cao, a resident of Fuzhou, China, saw a "giant snail" near Tongpan Road. Experts have identified this as the "African giant snail", one of the first harmful invasive alien species announced in China, and in the 1980s, many people in Fujian had farmed it, but after being banned, farmers threw them into the wild. This snail can spread tuberculosis and eosinophilic meningitis, so it cannot be touched by hand, let alone eaten. It has long been banned by China, and this time it was found in Rongcheng District, suspected to be secretly cultivated.
That said
Harmful species for this invasive
See how to get rid of it?
If a large number of African snails are found in the community, they can be told to the property to deal with, and companies specializing in killing pests and diseases can also deal with them.
If a small number of large snails are found at home, there have been news reports in Guangxi that there is a "soil method" in which a farmer kills African large snails with table salt, and the African large snails are partially melted into water after being sprinkled with salt and die.
Again!
African snails are infested!
