What kind of insect is the hornet?

Insects.

1. Wasps are widely distributed, with a body length of about 16 mm, orange antennae, wings and tarsus; the body is shiny black with yellow stripes and paired spots. Wasps are also known as yellow wasps, horse wasps, king bees (Guangxi), earth dragon bees, red-headed bees (Yunnan, Guizhou), and Taiwan giant hornets.

2. Wasp is a type of wasp, belonging to the suborder Slender-waisted of the order Hymenoptera, formerly known as the general term for the superfamily Vespoidea in the suborder Nephila.

Additional knowledge: The insects in this superfamily are commonly known as wasps, commonly known as yellow jackets. There are about 15,000 species in the world, and more than 5 species are known. Two species are recorded in China. They are predatory bees. Honeycomb structure: The honeycombs built by wasps in the subfamily Polistinae and Vespinae are made of dead branches, leaves or animal feces, not beeswax. This is different from bees and other wasps. The distribution area is all over the world.

Are wasps poisonous?

have.

The female wasp has a powerful long stinger. When attacked or disturbed unfriendly, it will attack in groups, which can cause allergic and toxic reactions in people, and in severe cases, it can lead to death. Wasps usually use soaked pulp-like wood pulp to build nests and eat animal or plant food.

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.

Additional information:

Wasps are a group of insects with social behavior. Species of the family Wasp usually do not have nests and live freely. When laying eggs, the female bee builds a mud chamber or chooses a suitable bamboo tube to lay eggs in it, and also stores larvae of other insects or spiders that have been caught and anesthetized by stinging. There is one egg in each chamber, and the openings are sealed separately. The larvae hatched from the eggs feed on the stored prey. After pupating and emerging as bees, they bite through the nest opening and fly out.

Other types of wasps live in nests throughout their lives. In a bee colony, there are queen bees, worker bees (or worker bees) (female) and drones. Queen bees are female bees that mate and fertilize with drones in the previous autumn. They store sperm in spermatophores and use them in batches this year. Drones die soon after mating. When the weather gets colder, fertilized female bees leave the nest and seek sheltered places such as cracks in walls and haystacks to spend the winter together.

Vespidae: Bees of this family, usually called wasps or hornets, are medium to large in size, with smooth bodies and various patterns. They have well-developed mandibles. Chewing mouthparts. Antennae are knee-shaped. Large compound eyes. Wings are long and narrow, folded together longitudinally when at rest. The abdomen is usually not contracted and is shaped like an abdominal stalk. Wasps have a simple social organization, with queens, drones and workers, and often build a papery bell-shaped or layered hive, where they live collectively. Adult wasps mainly prey on small insects of the order Lepidoptera, so they are also an important natural enemy of insects.

The scientific name of hornet is Vespa edulis, commonly known as hornet and wasp. It is highly poisonous. The venom of its sting contains phospholipase, hyaluronidase and a protein called antigen 5. Wasp stings should be treated promptly.

The principles are as follows:

1. Wasp venom is weakly alkaline, and the wound can be scrubbed with vinegar, 1% acetic acid or Wuji ointment.

2. After a wasp stings a person, no stinger remains on the body. (If it is a bee sting, the stinger remaining in the wound can be picked out with a needle or tweezers, but do not squeeze it to prevent the remaining toxin from entering the body. Then use cupping to suck out the venom and reduce the absorption of toxins.)

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

4. 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.

5. Observe closely for about half an hour. If you find any breathing difficulties, rough breathing, or wheezing sounds, even a little bit, immediately go to the nearest hospital for emergency treatment.

Replenish

A professor of entomology said that wasps are beneficial insects that feed on insects. They usually sting people only when they are attacked. There is no good way to prevent and control wasps. The usual methods are to burn them with fire or spray them with pesticides. If you encounter a wasp, it is best to squat down immediately and wrap your head with clothes, which can be a temporary prevention measure.

Experts remind: If you accidentally provoke a wasp to "get angry", you can lie down and not move, and never run wildly to avoid being chased by a swarm of wasps. After being stung by a wasp, the wound will immediately become red and swollen, and feel a burning pain. At this time, you should immediately apply some vinegar to neutralize the acid and alkali, reduce the toxicity, and also have a pain-relieving effect. If there are onions at the time, wash them, slice them and apply them on the wound. In addition, you can also use breast milk, wind oil, cooling oil, etc. to remove the bee venom, but remember not to apply red medicine or iodine, which will not only fail to treat, but will aggravate the swelling! If you are attacked by a swarm of bees, you should seek medical attention immediately and do not take it lightly.

Note: We would like to remind everyone to pay special attention to any injury and not to block the wound with soil, rags, dirty handkerchiefs, etc. to avoid tetanus and cause human death.

The most common bees we see are honey bees and wasps. If you are stung by a bee, its sting will remain in your body, so you can remove the sting first. Since bee venom is acidic, you can use soapy water or ammonia to clean it; if you are stung by a wasp, you should use vinegar to relieve pain and itching.

Wasps are poisonous.

Wasp venom:

Wasp venom is a poisonous liquid in the stinging gland at the end of the abdomen of the Vespidae family. The female wasp has a long and thick stinger at the end of its tail that is connected to the venom gland. After stinging, the venom is injected into the skin, but the stinger does not remain in the skin. The main components of wasp venom are histamine, serotonin, bradykinin, hyaluronidase, etc. The venom is alkaline and easily neutralized by acidic solutions. The venom has hemolytic, hemorrhagic and neurotoxic effects, which can damage the myocardium, renal tubules and glomeruli, especially the proximal renal tubules, and can also cause allergic reactions. Modern scientific research has shown that low doses of wasp venom have a powerful and good effect on the human nervous system, cardiovascular system, blood circulation system, and endocrine system.

It is poisonous, and actually dangerous. If some people are allergic to wasp venom, it can be fatal. Some time ago, the TV reported that an old lady was killed by a wasp. So we should not take it lightly. After being stung, go home and rub it with cooling oil or universal oil to clean the wound, remove the poison, and reduce swelling. If the swelling does not go down after a long time, you should go to the hospital. Generally, people with good resistance will recover within two hours. Children should be careful and not be careless.

Because hornets have evolved a means to protect themselves in natural activities, hornet venom is also a medicine that can treat many diseases. The toxicity of hornet venom is very small and generally not dangerous.
