Why did bees evolve stingers when they sting?

We all know that bees can sting, and it is estimated that many people have been stung by bees, so many people are afraid of bees. As the old saying goes: if you hurt the enemy by a thousand, you will lose yourself by 800.

Bees will not sting unless they have to, because after a bee stings, it will die itself. But hornets, wasps, and the like don't. Bees:

Do you think I'm thinking?

Why do bees die after they sting? According to scientists' research, bees sting people with stinging needles at the end of their abdomen, and the bees that die after stinging people are limited to worker bees, worker bees are female bees that are not fully developed, and the "sting" that stings people is actually an oviposition that is not fully developed.

The stinging needle is composed of a back stabbing needle and two abdominal stabbing needles, followed by large and small venom glands and internal organs, the tip of the abdominal stinging needle has several small reverse fishing, when the bee stinging needle crab human body**, and then pull out the stinging needle, because the small barb is firmly hooked ** (human ** is elastic, the sting is not easy to come out), so the stinging needle and a part of the internal organs also fall off together, in this way, of course, the bee will die.

There is a deeper reason why bees must die after stinging: long-term evolutionary defense strategies.

Bees are highly social animals that are divided into queen bees, queen bees, and worker bees. Worker bees are not capable of reproduction, they are mainly responsible for building hives, collecting food, taking care of larvae, etc., and the only value of their existence: to ensure the reproduction of queen bees and queen bees.

On the one hand, after the bee stings and dies, it will also release chemical signals to provide "warning" to other worker bees (in ancient times, it was wolf smoke); On the other hand, if a bee does not die after stinging, it may infect the intruder virus and harm the colony. Just like the gecko's tail is reborn, the death of a few bees has little impact on the entire colony, the price is small, and it is worth it!

As the saying goes, evolution is a basket into which anything can be filled. The main natural enemies of bees are other bees, such as wasps, wasps, etc. The barbs of bees have evolved from fighting other insects, and they have never considered fighting people or getting caught when they stab them.

Bee: I didn't think it through! ......Humans are a bug for all animals!

It is to better protect yourself and your family.

In order to protect herself, there is nothing powerful if she is not stabbed.

Because it's something they produce for their own safety.

Originally, the original intention of the Evolution Thorn was to protect himself, but I didn't expect that someone would dare to take the fruits of his labor.

It's a kind of protection for yourself, so it evolved.

This is a sense of protection, and sacrifice is inevitable in order to protect the homeland.

It's a defect in evolution, but when you encounter danger, you can only die with the enemy.

Evolutionary imperfection means that bees are in the stage of evolving from thornless to stingy, but have not yet evolved from disposable stingers to reusable stingers.

And natural selection is not enough to push bees to evolve the power of stingers that can attack multiple times. Because the bees that die after each attack account for a small number of bee colonies, and the bees that die in battle are all worker bees that have no reproductive ability, even if a few mutants survive after stinging, this trait will not be passed on to the offspring and will be lost in the gene pool of the colony.

Because this is also a means for them to protect themselves.

Bees sting are used for defense, and because the bee's stinging needle has a barb on one side and a venom gland attached to the internal organs on the other, it will die after stinging. The questioner asks why a strategy has evolved over a long period of time

Does it allow bees to not only "get hurt" but also "die" in order to protect the colony? Because it is entirely possible that evolution may have another strategy: the venom glands and internal organs are not connected, and the bees can continue to work in the hive after stinging, wouldn't it be more advantageous?

But, contrary to our intuition, it is likely to be the former who is more advantageous.

First of all, bees are highly social animals and are divided into queen bees, queen bees, and worker bees. There is only one queen bee in a colony, hundreds of queen bees and tens of thousands of worker bees. The first two are responsible for the reproduction of the whole colony, while the worker bees are not capable of reproduction, they are mainly responsible for building hives, collecting food, taking care of larvae, etc.

Therefore, the core value of a large number of worker bees in a colony is to ensure the smooth reproduction process of the first two.

Therefore, the question to be "considered" in evolutionary strategies is how best to ensure the reproduction of the entire honey bee colony, and thus the queen and queen bees. In this respect, the cost of the worker bee sting and then dying is actually very small. On the one hand, the release of chemical signals that accompany the death of a bee sting provides a "warning" effect on other worker bees in the same colony. On the other hand, the death of worker bees after a sting is reasonably "disinfected--- if a worker bee is infected with an intruder's pathogen, it can lead to huge losses for the entire colony.

Moreover, for a large number of worker bees, the loss of a few or even dozens of bees will not affect the operation of the entire colony, which is completely acceptable.

We can also compare some solitary wasps, such as mud daubers and cicada killers. These wasps are not social, and there are no "worker bees", and the female bees have to raise their offspring on their own. They also have stings, but these stings are used for predation (to anesthetize the prey).

Therefore, after stinging, it will not fall off and die like the worker bees of bees, because the cost is too great.

To use another inappropriate analogy: if a gecko's tail is caught, it can be cut off in order to escape, and then reborn, because the harm of cutting off the tail is far less than the death of the individual. Or it can be compared to humans:

We have an immune cell called macrophages, which will engulf invading microorganisms to protect the safety of individuals, but many times because of the "toxicity" of microorganisms, they will enter into programmed death, and pathogenic microorganisms "die together".

Individual worker bees, like geckos and our macrophages, have stinged deaths that generally outweigh the disadvantages for the colony as a whole, and have evolved to be a successful strategy.

Since the bee does not sting, then the bee sting will always remain because it is a part of the bee's body. Until the dead are dried corpses, they are still there.

The number of bees that die after stinging is limited to worker bees, which are female bees that are not fully developed, and bee stings are actually incomplete ovipositors. Because the development is not complete, the person who is stabbed is left with the internal organs, and of course he will die without the internal organs.

As for the queen bee, the oviposition is fully developed and will be fine after stinging. But there are very few cases in which the queen bee uses it to attack enemies in her lifetime, except in a duel with other queen competitors when it is just hatched.

A drone is stingless because it does not have ovipositors at all.

Bees sometimes like to sting, which is related to the following:

1. The problem of bee species. In Hainan, there is a kind of local bee, a small one, this bee species is particularly fond of stinging.

2. Weather reasons. Sometimes it is cloudy or rainy to check on bees, which are also very fond of stinging.

3. When there is a lack of powder and honey. Friends who keep bees know that when the source of powder nectar is abundant. Bees are particularly docile, and some beekeepers check on bees when there is enough nectar to do so, even without taking any protective measures. But when bees lack honey and powder, they especially love to sting.

4. When checking the bees, put the nest frame back. If you don't pay attention often, you will crush the bee, and this is when the dead bee will convey the message. Bees become particularly ferocious. I've been stung a lot because of this.

5. When opening the beehive, the action is too loud and the vibration reaches the beehive, which will also make the bees love to sting. Once I was checking on the bees, opened the beehive and accidentally shook the beehive. As soon as I opened the beehive, I was stung more than 20 times, and finally I didn't dare to check it. Cover the beehive directly.

Bees also lose their antennae, and they will also lack some good body energy to die, which is also very bad for bees.

Bee colonies are generally composed of worker bees, drones and queen bees, there is a poisonous needle at the end of the abdomen of the worker bee, the poisonous needle is composed of a back-stabbing needle and two abdominal stabbing needles and is connected to the venom gland and internal organs, the tip of the needle has several small barbs in the shape of a chamfer, after stinging into a human or animal, the small barb can be firmly hooked**, and when it flies away, it will be pulled out together with some internal organs, resulting in the death of the bee after stinging, so the bee will not sting unless it is absolutely necessary.

Because after stinging, the stingers of the bees will remain on the human tissues with internal organs, so the bees will not survive.

The main reason is that the sting of the bee is actually connected to the intestines of the bee, and if it stabs into the human body, it will cause it to die.

Summary. Hello, glad to answer for you. Bees break their internal organs when they pull out their needles, so bees die after stinging.

Because the stinging needle will be barbed in the person's **, the bee sting and the bee's internal organs are connected together, and the bee's internal organs will remain on the person's ** after stinging, and the bee's internal organs will not survive long after being broken.

Why do bees die after stinging?

Hello! I have understood the problem, I am now typing the reply content, give me a moment Thank you for your understanding

Hello, glad to answer for you. When the bee pulls out the needle, it will break the internal organs, so the bee will die after stinging. Because the bee stings after the needle will be barbed in the person's **, the bee sting and the bee's internal organs are connected together, the bee sting will remain on the person's ** after the sting, and the bee's internal organs will not survive long after the spring will die.
