Red imported fire ants hurt people in many places, so don't touch them. According to the data, Solenopsis invicta was introduced into China through foreign garbage in 2004. In just over ten years (as of April 20021year), red imported fire ants have been found in many provinces and cities in China, and red imported fire ants hurt people in many places, so don't touch them.
There have been many incidents of red imported fire ants hurting people. Don't touch 1. It is reported that recently, in a community in Haikou, residents found many ant nests on the lawn, and some crimson ants kept crawling in and out.
These ants are very aggressive, and many residents in the community are accidentally bitten. Later, after on-the-spot identification by experts, these biting ants are the alien invasive species in China-red alien fire ants.
So, what is red imported fire ant? How terrible is this creature?
Solenopsis invicta is recognized as an ant without "natural enemies" in the world. Strong adaptability to the environment, amazing reproduction speed and super destructive power. It can be said that if there are red imported fire ants in a place, it is basically impossible to completely prevent and eliminate them.
As mentioned above, Solenopsis invicta is an alien invasive species in China. So, how did they enter our country? This needs to start from 2004.
Red ants first appeared in Taiwan Province Province, China, and then entered Guangdong from Taiwan Province Province. The earliest red imported fire ants were discovered in Chinese mainland in September 2004, and then, in less than two years, they spread to many provinces in southern China, including Hong Kong and Macao.
Now, in less than 20 years, red imported fire ants have spread all over China 12 provinces, and they can be seen in both cities and villages. They not only bite people, but also harm the surrounding agricultural and forestry plants and bite other animals, such as pets and livestock raised by humans.
Many friends think that it may take several days to get well after being bitten by ants, but the toxicity of red imported fire ants is very great. If not treated in time, it may be life-threatening.
In July, 2065438+August, a man in Guangxi was bitten by a red imported fire ant that climbed on his leg. Not long after, the man fainted to the ground and his breathing and heartbeat suddenly stopped. The family quickly dialed 120, but when the ambulance arrived, the man was already dead.
In July 2020, a worker in Shenzhen suddenly ran out of an old box while cleaning, and one of them bit him. The next day, the workers began to have a high fever and a rash began to appear at the bitten place. After being sent to the hospital, he developed symptoms of multiple organ failure and almost lost his life.
June 5438 +2020 10, a woman in Guangdong was accidentally bitten by a red alien fire ant while playing in the scenic spot. At first, the woman didn't take it seriously. I didn't expect to have a headache later, and I was shocked for a while. Even when she was taken to the hospital, her heart suddenly stopped beating. Fortunately, after the doctor's rescue, the woman was finally safe and sound.
In July of 20021year, a woman in Guangxi was bitten by a red imported fire ant outdoors, and she had a high fever that day. After her family was sent to the hospital, the situation improved, but I didn't expect the woman to leave the hospital and go home without authorization, and finally she suddenly became ill. The situation was critical. She died before being sent to the hospital.
There are many similar situations. From these things, we can see that red imported fire ants are terrible. So, why is it so dangerous to be bitten by red imported fire ants?
Speaking of it, this is because the red imported fire ant is a highly toxic animal. When bitten by it, a large amount of its venom will enter the wound, and then a series of toxic reactions will occur on the affected skin, such as redness, itching, and even pustules, which will easily lead to bacterial infection and eventually threaten life.
So, if you are bitten by red imported fire ants, how can you save yourself?
Although there are indeed cases of death after being bitten by red imported fire ants, there is no need to worry too much, because if you are in good health and seek medical treatment in time, there will be no big problem.
Under normal circumstances, people with poor health and low immunity are more likely to have violent reactions after being bitten by red imported fire ants. If they are unlucky, they will have coma, cardiac arrest, respiratory failure and so on. , they may be powerless.
However, this is also very rare, because most people just have symptoms of papules, and then they just need to deal with them in time. The first thing to do is to wash the bitten part with alkaline soap and wash it with plenty of water, which can weaken the venom. After that, you should go to the hospital immediately, take some drugs orally according to the doctor's advice, or have in-depth treatment.
Finally, I would like to remind you that if you see a big mound outdoors, it can be about 50 cm high at most. Never touch it, and be sure to stay away as soon as possible, because such a small mound is likely to be the nest of red imported fire ants, especially in your area, red imported fire ants have invaded, so be more careful!
There have been many incidents of red imported fire ants hurting people. Don't touch them. According to Red Star News, on April 30, 2022, a little boy in Xichang City, Sichuan Province was attacked and bitten by a red alien fire ant while playing outside, causing anaphylactic shock. Fortunately, the traffic police escorted him to the hospital for medical treatment. At present, after the rescue, the boy's vital signs are stable and are under further observation.
Fire ant is just an ant. Why is it so serious after being bitten? According to the news, someone has died! What is this red imported fire ant and why is it so powerful?
Fire ant: an ant more powerful than a military ant.
Solenopsis invicta (scientific name: Solenopsis invicta) is native to parana river Valley in South America. It is a social insect with a body length of only 2~6 mm. Like other ants, its body is divided into three parts: head, chest and abdomen, with three pairs of feet and a pair of antennae.
Of course, there is also a big claw pliers and a needle at the end of the abdomen. The most terrible thing is this needle, because the venom in its body can penetrate the target through the needle. The venom of Solenopsis invicta contains piperidine, alkaloids and toxic protein. This water-soluble toxic protein can cause severe allergic reaction and even lead to anaphylactic shock death.
After a person is bitten, there will be a very strong burning and itching sensation near the wound, which is also the origin of the name of the red imported fire ant, because it hurts like a fire after being bitten! After being stung, a few people who are allergic to the body have dizziness and coma and need to be sent to the hospital for rescue. Most injured people can take anti-allergic drugs and apply ointment after seeing a doctor.
Solenopsis invicta is not only poisonous, but also a species with strong social organization! You must know about military ants, and I guess everyone has heard of their terrible things. For example, wherever an army ant goes, animals are killed and soon become a pile of bones, but this army ant is no match for red imported fire ants. According to the observation records of entomologists, the exchange ratio between the warring sides reached 1: 6.2, which means that a red imported fire ant can kill 6.2 army ants, which is really terrible.
What is even more frightening is their adaptability.
Solenopsis invicta has strong adaptability to the environment. As long as the temperature in winter is not lower than MINUS 17 degrees, they can basically adapt to survival, and unlike other ants, they are very adaptable. They prey on earthworms and feed on the seeds, fruits, buds, tender stems and roots of crops, which is very destructive. Wherever red imported fire ants go, the land is hardened, crops fail, and farmers are stung while working.
Many States in the southern United States have basically been invaded. On the global distribution map of red imported fire ants, the southern part of the United States is purple, indicating that its distribution density is extremely high. According to the statistics of the United States Department of Agriculture, the density of nests in farming areas can reach 200 per acre. In winter, they will move their nests to roads or human buildings for the winter, so people and animals are often bitten by red imported fire ants.
Such a terrible species has bad news for you. They are extremely fertile! Like other ant species, red imported fire ants can be divided into worker ants and soldier ants. The queen ant has 1500 to 5,000 eggs a day, and a nest of ants can reach 1000 to 250,000. Its amazing fertility is staggering.
And the most terrible thing is that as long as the ant colony flies, it can find a new nest to establish a stronghold, and the average life span of the queen ant is 6 to 8 years, so it is necessary to eliminate the queen ant when it is eliminated, otherwise it will not be long before it can make a comeback.
Invasion of China 12 province: still spreading.
According to the data, Solenopsis invicta was introduced into China through foreign garbage in 2004. In a short period of more than ten years (as of April 20021year), Solenopsis invicta has been found in many provinces and cities in China, including Zhejiang, Fujian, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Hainan, Chongqing, Sichuan, Guizhou, Yunnan and other places.
It can be described as follows: under the attack of red imported fire ants, almost the whole south has fallen, and it is still spreading! Solenopsis invicta has a great influence on agriculture in China. Their recipes are highly coincident with human staple crops, including soybeans, corn, eggplant, and even saplings and plant roots are welcome!
On 20021August 18, Outlook Think Tank published an article about the spread and harm of Solenopsis invicta in China, in which the harm to crops and people ranked first!
Although red imported fire ants have a great influence on agriculture, it is inevitable that they will appear in agricultural areas and have an impact on people. The first death of red imported fire ant in China occurred in Taiwan Province province. On October 20th, 2004, a woman from Taoyuan County was admitted to Guangxin Hospital. She vomited after being bitten by red imported fire ants and died within one day after being taken to the hospital.
The first death case in Chinese mainland occurred in a town in Dongguan on June 4th, 2006. The deceased was a 46-year-old local female greening worker who was bitten at work and died of anaphylactic shock five days later.
However, it is difficult to count the number of people bitten by red imported fire ants. In many cases, the waste of farmland is not due to the shortage of labor, but the work in farmland is often bitten by red imported fire ants. Simply abandon the land and go out to work, and the red imported fire ants will have less trouble! At the end of April, 2002/KLOC-0, a researcher from the Ministry of Agriculture found that there were about 3,000 nests of red imported fire ants in a 200-mu farmland. Working in a place like this is really risky.
As early as 2005, the Ministry of Agriculture and Rural Affairs predicted that in the next 35 years, if effective prevention and control measures were not taken, red imported fire ants would cause economic losses of 654.38+028.04 billion yuan. From the current point of view, this forecast may be optimistic about the forecast of that year.
Red imported fire ants are so terrible, how to prevent them?
Red imported fire ants are the most widely distributed in the world, and the most influential is the United States. Maybe their operation can be used for your reference! The United States used to spray a lot of pesticides on planes to kill red imported fire ants, but as you can guess, it killed not only red imported fire ants, but also other insects. This is an ecological disaster!
Later, American scholars proposed to introduce and use three parasitic fleas and flies to control the local red imported fire ants. However, this parasitic flea and fly can only attack the external foraging red imported fire ants, and there is nothing to do with the underground queen, which will still produce red imported fire ants continuously. If there is a special way to attack the queen ant, it will be uprooted.
Up to now, there is no suitable large-scale control method, and only pesticides, such as powder and poison bait, can be sprayed directly to trap and kill red imported fire ants. Although this operation consumes a lot of manpower and material resources, it is indeed an effective control method for the rapid spread of red imported fire ants.
On March 9, 20021KLOC-0, nine ministries and commissions jointly issued the Notice on Strengthening the Prevention and Control of Solenopsis invicta, requiring all localities to carry out the work of killing Solenopsis invicta, hoping to curb the spread of Solenopsis invicta within 3 to 5 years. However, the life of Solenopsis invicta is very tenacious, and it is extremely difficult to eradicate it from our land, but controlling its spread speed or density is also a great achievement.
Red imported fire ants have hurt people in many places. Don't touch it. On May 6, Jiangxi released a message. The staff of Rongjiang New District in Ganzhou, Jiangxi Province have received many phone calls from the masses, saying that there are red imported fire ants in villages and fields, and there are injuries.
According to Red Star News, on April 30th, in Liangshan, Sichuan, a little boy was bitten by a red imported fire ant, causing anaphylactic shock and dying. After the rescue, the little boy's life characteristics are stable.

Solenopsis invicta has strong reproductive ability, fast transmission speed, strong aggression and high bite toxicity, which can cause burns, pain and even shock death. From May to June165438+1October, red imported fire ants entered a period of frequent activities, which were mostly found in green belts, public green spaces, abandoned land and river banks along sidewalks.
Solenopsis invicta, whose Latin name means "invincible ant", is native to South America and is recognized as one of the most dangerous invasive species in the world. According to official website, the Ministry of Agriculture and Rural Affairs, as of 202 1, there were 632 1 10,000 mu of red imported fire ants in 534 counties (cities, districts) of two provinces (autonomous regions and municipalities) nationwide, an increase of 64 1 10,000 mu over the previous year.
According to the data from the Red Fire Ant Research Center of South China Agricultural University, red fire ants are widely distributed. In the south of China, except for areas with high plant coverage such as forests, they can all invade, and areas disturbed by human beings are more suitable.
Lu Yongyue, director of the Red Fire Ant Research Center of South China Agricultural University, said in an interview with CCTV news, "Red Fire ants can not only nest in infrastructure, causing short circuit of wires or facility failure, but also attack with the upper jaw, and the needle at the end of the abdomen keeps stabbing people and animals. And release venom. This venom includes water-soluble protein, formic acid, alkaloids, etc. , make people feel burning pain after being stung, and then blisters, purulent, severe allergic or even shock.
According to Lu Yongyue, a comprehensive prevention and control model of red imported fire ants suitable for different environmental conditions and different occurrence degrees has also been integrated. There are 8 kinds of pesticide active ingredients and more than 40 kinds of pesticide preparations registered for controlling red imported fire ants.
The Red Fire Ant Research Center of South China Agricultural University suggests that if you find suspected red fire ants, you should pay attention to stay away from them and don't interfere to prevent being stung; Second, it is necessary to report to the local agricultural bureau or the landscaping department in time, so that professionals can identify and kill.
Jiang Nan, an emergency physician of Xuanwu Hospital of Traditional Chinese Medicine in Beijing, said in an interview with Health Times that if the bite of the red imported fire ant is mild, the bitten part can be cleaned with clean water or soapy water or cold compress, and treatment can be carried out under the guidance of a doctor if necessary. If the patient is not treated in time after being bitten and his condition gets worse, dexamethasone or methylprednisolone should be injected intravenously, or even adrenaline should be injected intramuscularly.
