Is dying after a bee stings the best option based on evolution?

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 we can compare it with humans: we have an immune cell called macrophages, which will devour 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.

The bees that die after stinging are limited to worker bees, which are female bees that are not fully developed, and the "sting" that stings people is actually an oviposition that is not fully developed. 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. The male peak is spinless because it has no ovipositors at all. The only bees that can sting and die are the bee genus, they are large groups, there is no big problem in sacrificing one or two worker bees, and the other bees are single or small groups, and they cannot sacrifice themselves casually.

"Honey bee" belongs to the genus Honeybee of the family Honeybee family, the general family of Apiaceae in the order Hymenoptera. Whereas, the suborder Slender Waist is divided into the tail of the needle and the tail of the cone. Only members of the tail of the needle have the term "acupuncture".

In fact, the ovipositor is specialized) In this way, the bee that can "sting" is reduced to the tail of the needle. The needle tail is mainly divided into 7 general families (11 families) of the honeybee family, the ant family, the green bee family, the wasp family, the spider bee family, the earth bee family, and the mud bee family. And among them, the general family of ants obviously cannot meet the question "which bees sting people will not die?"

This said. Because it's not a "bee". Although the green bee family, the spider bee family, the earth bee family, and the mud bee family are all parasitic bees, they still have attack power.

So it probably won't be present (because these bees are all monolithic.) If they all die after stinging, then this species must have ceased to exist. Personal egg pain explained.

The tragic <> of the bee genus worker bees

This is because bees are very poisonous, and if they are stung by bees, they are likely to become infected, so they are likely to die.

Because the stinger of the bee is connected to the internal organs of the bee, when the stinger pierces the human body, the intestines will also be pulled out, and the bee will of course not survive.

The poison needle at the end of the bee's abdomen is composed of a back-stabbing needle and two abdominal stabbing needles, the back of the needle is connected to the venom gland and internal organs, and the tip of the abdominal needle has several small barbs in the shape of inverted teeth, when the bee's poison needle stings into the human body, the venom is discharged and then pulled out of the stinging needle to fly away in a hurry, because the small barb is firmly hooked, so the poison needle is also pulled out along with a part of the internal organs, so that the bee will of course die.

<> "Everyone knows that bees sting, so there are many people who are afraid of bees. In fact, bee stings are a last resort, and bee stings are risking their lives, because bees will die after stinging.

What is the reason why a bee will die after stinging? It turned out that the bee sting used a needle at the end of the abdomen, and the needle was composed of 3 needles, namely 1 dorsal needle and 2 abdominal needles, which were connected to the large and small venom glands and internal organs, and several small barbs were born at the tip of the abdominal needle;

When the bee stinging needle pierces the human body's **, and then pulls out the stinging needle, because the small barb firmly hooks the **, so the stinging needle is pulled out together with a part of the internal organs, so that of course, the bee will not live.

Therefore, bees do not sting until they are in a critical moment. But when a bee stings an insect that has a hard epidermis on its body, it can pull the needle back from the crack and save itself from death.

It seems that bees pose little threat to orange crackers, so we try not to provoke bees when we encounter them, so as not to sting ourselves and kill the bees, which is really a lose-lose situation.

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.

Why do bees die immediately after stinging?

If it threatens the life of the bee or threatens the hive, the bee will desperately sting to defend itself and the hive.

Because behind the needle are connected to the venom glands and internal organs.

Because if the bee is threatened, he will desperately defend his own interests.

Bees don't sting unless they have to.

Protect your homeland.

The poison needle at the end of the bee's abdomen is composed of a back-stabbing needle and two abdominal stabbing needles, the back of the needle is connected to the venom gland and internal organs, and the tip of the abdominal needle has several small barbs in the shape of inverted teeth, when the bee's poison needle stings into the human body, the venom is discharged and then pulled out of the stinging needle to fly away in a hurry, because the small barb is firmly hooked, so the poison needle is also pulled out along with a part of the internal organs, so that the bee will of course die. Therefore, bees do not sting unless they have to.

The poison needle was pulled out along with some of its internal organs.

It's an instinctive reaction, and when threatened, it will sting.

Because bees are threatened to defend their hives.

That's his stress response, instinctively.

It's an instinctive response, engraved in its genes.
