The name of the killer bee is so scary, can this kind of bee really kill humans?

Various matings with killer bees, also known as African killer bees and membrane-winged bees, have emerged. There have also been incidents in China where wasps and Nana have also caused allergies, shock and death. But wasps belong to the family Polistidae of the order Hymenoptera; killer bees are new species that are crossbred with common African honey bees and jungle wild bees. They are very lethal to humans and animals, and the main harm caused by African bees lies in their aggressiveness. As mentioned in reference 1, their aggressive behavior may be related to the secretion of pheromones. Killer bees (bees) are herbivores. Bumblebees (see illustration) and hornets feed on pests and other bees. They all have the habit of eating pollen. These bees are also insects that are beneficial to the natural environment and ecological construction. Various pests in the forest are often used as prey, so they play a great role in preventing forest pests and diseases.

In an attempt to improve local bee species, it was found that some introduced bees escaped from the laboratory and hybridized with local bees to produce hybrid bees (i.e. Africanized bees). They have good adaptability to the local climate and nectar source conditions, reproduce quickly, and have high honey production, but they are very tillering, and can get bees almost every month throughout the year. Africanized bees often chase people and animals near the hive in groups, causing casualties, and are called "killer bees." Africanized bees spread outward at a speed of 100 to 200 kilometers per year, quickly spreading throughout South America and invading the United States. The real danger posed by "killer bees" is not to humans, but to local bee colonies. Because the local bee colonies will soon be wiped out by "killer bees." Dozens of "killer bees" can wipe out tens of thousands of bees in a short period of time. But it is worth noting that the Japanese bees have come up with amazing tactics to prevent killer bee attacks.

When a killer hornet breaks into a hive, it's larger than any of the bees. But the Japanese bees use their numbers to strategic advantage. Specifically, the Japanese bees will pounce on the attacking hornet, completely surrounding it. At the same time, the bees begin to generate heat by beating their wings at top speed, effectively cooking the killer blay to death.

Honey bees' stings can't penetrate the wasp's thick shell, so instead the bees form a spherical "bee ball" around their attackers, using vibrating flight muscles to generate heat. The mass of these bees is enough to raise the temperature of the area to 116 degrees Fahrenheit (about 47 degrees Celsius), killing the hornet. Scientists discovered these "bee balls" in 2005 and have been studying them ever since. Now, researchers have revealed the bee brain mechanism that controls the fiery "bee ball" behavior of Japanese honey bees, but their close relatives, European honey bees, do not have this behavior.

Yes, because this type of bee is a hybrid of two different types of bees. It is highly aggressive and poisonous. Once a human is attacked, it is attacked by a group of bees, which can easily cause allergic shock and respiratory distress, and in severe cases, it can be fatal.

Killer bees can really kill humans, because killer bees have a high level of toxins, which are very toxic. Once they penetrate the human body, they will cause great harm to the human body. In serious cases, they can kill humans.

Yes, because the venom of this kind of bee is extremely strong. Once it bites a person, the person will die quickly from the poison and the vital signs will disappear.

Why can a wasp sting kill people?

The venom in the poison sac at the tail of bees and wasps penetrates the skin and enters the human body through a stinger connected to the poison sac at the tail end. Bee venom contains formic acid, histamine-like substances, hyaluronidase, phospholipase A, neurotoxins, etc., which can cause systemic symptoms such as nerve, hemolysis, and bleeding in addition to local reactions to stings. People who are allergic to bee venom may have allergic reactions. After a bee stings a person, the stinger breaks and remains in the wound; after a wasp stings a person, the stinger can retract and sting repeatedly. After being stung by a bee, a person will have local pain, redness, swelling, and numbness, which will heal on their own after a few hours; blisters will appear at the sting site in a few cases, and there are rarely systemic poisoning symptoms. Being stung multiple times by a swarm of bees will cause fever, headache, nausea, vomiting, and diarrhea in a very short time. In severe cases, hemolysis, bleeding, irritability, muscle spasms, convulsions, coma, and acute renal failure will occur. People who are allergic to bee venom will quickly develop urticaria, laryngeal edema and/or bronchial spasm, which can lead to suffocation and anaphylactic shock.

After being stung by a bee, the stinger will remain in the skin. You must use a sterilized needle to remove the stinger, then pinch the stung part and suck it repeatedly with your mouth to suck out the toxin. If you don't have any medicine with you, you can wash the affected area thoroughly with soapy water and then apply some vinegar or lemon.

2. In case of shock, be careful to keep the airway open and perform first aid such as artificial respiration and cardiac massage while notifying the emergency center or on the way to the hospital.

The scientific name of hornet (insect) is "vespa", also known as "ant bee" or "yellow wasp". It is large and long, and has a high toxicity. It is a stinging insect in the suborder Apocrita (formerly known as Aculeata) of the order Hymenoptera, except for bees and ants. It is a widely distributed, diverse, fast-flying insect. It belongs to the family Vespidae of the order Hymenoptera. The female bee has a powerful long stinger on its body. When it encounters an attack or unfriendly interference, it will attack in groups, which can cause allergic reactions and toxic reactions in people, and in severe cases, it can lead to death. Hornets usually use soaked pulp-like wood pulp to build nests and eat animal or plant food.

There is a stinger formed by an ovipositor at the end, connected to a poison sac, which secretes a strong venom. The pupa is a yellowish-white pupa, and the color deepens with age. The head, thorax, and abdomen are distinct, and the main organs are clearly visible. Many maggots overwinter as pupae. The larvae are spindle-shaped, white, and legless. The body has 13 segments.

Wasps have chewing mouthparts and antennae with 12 or 13 segments. They are usually winged, with a slender waist connecting the thorax to the abdomen, and a formidable sting on the abdomen. Adults feed mainly on nectar, but larvae feed on insects provided by the mother. There are more than 20,000 known species, most of which are solitary. Social wasps are limited to about 1,000 species of the Vespidae family in the superfamily Vespoidea, which also includes the giant wasps and yellow jacket wasps. These species differ from species of the Pompilidae family (also in the superfamily Vespoidea) and other wasps in that their wings are folded lengthwise when they are at rest.

The appearance of the wasp's adult body also has the standard characteristics of insects, including head, thorax, abdomen, three pairs of legs and a pair of antennae. At the same time, its simple eyes, compound eyes and wings are also common to most insects. In addition, a degenerate oviduct is hidden at the end of the abdomen, which is the poisonous bee sting. The adult body is mostly black, yellow and brown, or a single color. It has different sizes of punctures or is smooth. The hairs are generally short. The legs are long. The wings are well developed and fly quickly. The front wings are folded vertically when they are still, covering the back of the body.

The mouthparts are well developed, and the upper jaws are relatively strong. The male bee has 7 segments on the abdomen and no stinger. The female bee has 6 segments on the abdomen, with a stinger formed by an ovipositor at the end, connected to a poison sac, which secretes venom with strong toxicity. The pupa is a yellow-white pupa, and the color deepens with age. The head, thorax, and abdomen are distinct, and the main organs are clearly visible. Many wasps overwinter as pupae. The larvae are spindle-shaped, white, and have no legs. The body has 13 segments.

Toxins and stings: Wasp toxins are divided into two categories: hemolytic toxins and neurotoxins. They can cause liver, kidney and other organ failures. Especially if they sting a person's blood vessels, they are life-threatening and are especially dangerous to people with allergies. Wasp stingers do not have venom glands and can launch multiple attacks or stings on people.

When you are stung by a wasp, you should try to apply ammonia water. If you don't have it, you can use your own urine. Try to apply onion, which can also have a certain effect. I don't know how long you have been stung. If you don't have systemic symptoms such as difficulty breathing, dizziness, chest tightness, numbness of hands and feet, you can take anti-allergic drugs such as chlorpheniramine, astemizole or hormone drugs such as prednisone. If you are worried, you can go to the hospital for intramuscular or intravenous injection. Drinking a lot of water and rehydration is one of the ways to promote the body to eliminate toxins.

Emergency treatment principles:

1. When stung by a bee, the local skin will feel pain and itching, accompanied by allergic stimulation and local inflammatory reactions such as redness, swelling and heat. If the bee's stinger stings into the skin, it must be removed.

2. Apply ice to the sting to relieve pain and swelling. If the pain is severe, you can take some painkillers.

3. If there is a tendency to spread, there may be an allergic reaction. You can take some anti-allergic drugs, such as diphenhydramine, promethazine and other anti-allergic drugs.

4. Observe closely for about half an hour. If you find that the patient has difficulty breathing, or his breathing becomes rough or there is a wheezing sound, immediately send him to the nearest hospital for emergency treatment.

Generally, if you are slightly hurt, you won’t die;

However, some hornets are extremely poisonous, and just a few of them can kill a person;

It also depends on the individual's constitution - how sensitive they are to toxins. The more sensitive a person is, the greater the harm they will suffer.

Bee stings are poisonous

But the amount is small

Usually not fatal

If there are no large number of bee stings

If the toxin reaches a certain amount

The heart will stop beating

The stinger at the end of the bee's abdomen is composed of a dorsal stinger and two abdominal stingers. The back of the stinger is connected to the venom gland and internal organs. The tip of the abdominal stinger has several small barbs in the shape of inverted teeth. When the bee's stinger stings into the human skin, the venom is discharged and the stinger is pulled out to fly away in a hurry. Because the small barbs firmly hook the skin, the stinger and part of the internal organs are pulled out together, so the bee will of course die. The wasp is different. Its stinger does not have barbs, so it will not die!
