The invasion case of the African giant snail, how to eliminate the African giant snail

In July 2014, Ms. Cao, a citizen of Fuzhou, China, saw a "giant snail" near Tongpan Road.

In the 80s of the 20th century, there were many people in Fujian who farmed, but after being banned, farmers threw them into the wild. This snail is very destructive, harming more than 500 crops, and even cement can be eaten. Moreover, this snail can transmit tuberculosis and eosinophilic meningitis, so it should not be touched by hand, let alone eaten.

It has long been banned in China, and this time it was found in Rongcheng City, and it is suspected that someone is secretly breeding.

This giant snail is peculiar, the snail is nearly 10 centimeters long, and the shell is yellow-brown and patterned. The shell is spiral-shaped and hard.

The African giant snail is native to Africa, can grow up to 20 centimeters, food includes crops, trees, fruit trees, vegetables, flowers and other plants, when hungry also eat paper and companion corpses, and even can gnaw and digest cement, can harm more than 500 kinds of crops, in Fujian activity period is mainly from April to November every year.

The African giant snail is also an intermediate host for human-animal parasites and pathogenic bacteria, especially tuberculosis and eosinophilic meningitis. In addition, the vegetables and fruits they have crawled on may have residual pathogens that can invade the human body.

Although the African giant snail reproduces very quickly, it has natural predators and can be killed with pesticides, so it has not caused a large-scale outbreak.

<> methods of eradicating the African giant snail: mechanical control, agricultural control, chemical control.

1. Mechanical prevention and control. It can be used at dawn, dusk, night or after a thunderstorm to forage for snails to be hunted manually, and its habits can also be used to trap and kill with food.

2. Agricultural prevention and control. Using agricultural cultivation measures, snails like moisture but avoid water, and water-upland rotation can kill snails, eradicate weeds around flower beds and vegetable fields, destroy their places, and also reduce the occurrence of snail harm.

3. Chemical control. Commonly used methods are: spray with tetraacetaldehyde (, using 10 kg ha, or spray with 15% tetraacetaldehyde powder 50 kg ha, 4% carbamate 100 kg ha, copper sulfate 125-250 kg ha, iron sulfate 125-250 kg ha.

I organized the album and flipped to the snail that I took during the summer vacation.

I remember that after dinner, I met two big snails on the side of the road, I broke a leaf, picked them up, and took them to the rooftop to be a model.

At that time, I didn't know that it was a giant African snail, put it on the rooftop, and took pictures of it, and the snail crawled much faster than I expected, and I saw him stretch out his tentacles, slowly poke his head out, and crawl towards the edge.

The first time I saw the snail's teeth, the lines on the **, it was a little disgusting up close, but when I looked at it, I felt a little cute.

I like to take pictures of everything, this time I picked up is not a good thing, I took a few **, checked whether this is a snail or an ordinary snail, I know, I picked up two African snails.

My friend told me not to touch it, it's poisonous, snails are pests ......

Its food includes crops, trees, fruit trees, vegetables, flowers and other plants, and when it is hungry, it also feeds on paper and the corpses of its companions, and can even gnaw and digest cement, which can harm more than 500 kinds of crops. This species is an intermediate host for many animal parasites and pathogenic bacteria, especially tuberculosis and eosinophilic meningitis, which are extremely harmful when consumed. The African giant snail can lay between 30 and 700 eggs at a time and reproduce quickly.

After the rain the next day, there was basically a snail in two steps on the road, and I slowed down and looked closely, as if I had broken into the snail kingdom.

I didn't think the snail was terrible, but the reproduction speed was really amazing, and I even felt a little cute when I took a shot, so I had the following series of ......

Move forward at a speed visible to the naked eye.

Somewhat curious, carefully observe the 4 or so tentacles on its head, and the eyes are in **.

In an interesting painting, there is a small snail underneath the big snail, which looks like a snail family.

Such little snails are everywhere, and if you accidentally step on several of them.

Are snails really scary?

I didn't know much about the African giant snail, but I came across it by chance and felt a little loved, so I patted it.

Do you know anything about snails? What do you think, are snails cute or scary?

The African giant snail itself carries the virus, but if you don't eat it, it won't be contagious. So, can the African giant snail be touched? If you accidentally touch it and are worried about spreading the virus, you can wash your hands with disinfectant or soap.

In the African giant snail, there are many parasites and bacteria that can cause viral infections. Infected people can cause very powerful viruses such as tuberculosis and eosinophilic meningitis. Eating is extremely harmful.

The African snail virus is transmitted to humans mainly through consumption. Usually, it is eaten raw or half-cooked. Bacteria and parasites in the body cannot be burned to death.

If you touch your hands, wash your hands frequently with soap to reduce the chance of illness and parasitic infections. African snails, whether bred in captivity or in the wild, should go to the hospital immediately if they have wounds on their hands that come into contact with snail mucus. In short, there is the possibility of viral and parasitic infections.

The precautions and disinfection measures taken are only to reduce the chance of getting sick. If we are not infected, then the chances of getting sick are zero. Otherwise, we will be 100% sick.

Therefore, in our daily life and work, we must develop good habits and precautions.

African giant snails can be raised, and people in many countries keep them as pets. It mainly eats vegetables, flowers, and other crops, so it will be considered an invasive species. It prefers to live in a damp, dark environment.

Most of them are active in farms, orchards, weeds and crops. Usually, they can grow into adulthood in about four months, and grow slowly in adulthood. In a breeding environment, it can survive for 4-6 years.
