In life, what is the principle of firefly light?

Introduction: Fireflies.

It is a very beautiful insect, because it will emit light and give people a lot of reverie, and there will be fireflies in many stories, which also makes the night more wonderful. In life, what is the principle of the glow of fireflies?

In fact, fireflies emit light mainly because they contain a certain substance in their body, and not all fireflies emit light. The act of male fireflies emitting light and female fireflies that do not emit light and glow is mainly for courtship. In the summer, glowing fireflies can be seen, mainly because the tails of fireflies contain a phosphorus-containing substance, which is a very active metal that burns when exposed to direct air.

Therefore, when the tail enters the air, and there is a catalyst in the body of the firefly, it can burn and emit light under the action of catalysis. However, this burning behavior is not very harmful to you, so people don't have to worry. And the light of fireflies is very bright, and if you can put a lot of fireflies in one place, it can indeed illuminate.

So there are a lot of people who are very fond of fireflies, but fireflies also represent the quality of the local air.

In the past, there were a lot of fireflies, but in the summer, few people could see them.

In fact, with the acceleration of urbanization, many rural areas have become towns, but this also means the former ecosystem.

It has been affected to a certain extent. At night, many buildings are polluted by light, and the cars on the street are very noisy at night, which affects the previous insect habits, resulting in the disappearance of insects that could be seen often in the past. Therefore, people should also pay attention to their own production and life in their daily life, and pay attention to the impact on nature.

Some landscape lights are not necessary to turn on at night, and this consumes electricity.

Fireflies have some structures on their bodies that can emit light and react when they come into contact with air, so they cause fireflies to glow.

Mainly using the principle of luminescence, fireflies contain a special substance in the body, which is directly exposed to the air, so there will be a situation of luminescence.

1. This is due to the light produced by a chemical called insect luciferase in the firefly that interacts with oxygen. The chemical, called insect luciferase, initiates this reaction like a switch, and when the fireflies produce insect luciferase, the reaction begins, and the fireflies emit flashes of light.

2. The reason why fireflies glow.

First, glowing is for courtship. Because different species of fireflies emit light in different ways, isolation is naturally formed between species. The vast majority of firefly species are males with luminaires, while females have no luminaires or are less developed.

Male and female glow and attract each other to chase each other, looking for their own satisfactory object.

Second, the glow is to frighten the enemy. In 1999, scholar Knight and others found that lizards that accidentally ate adult fireflies would die, confirming that the glow of adult insects not only looks for mates, but also warns other organisms; In 1997, scholars Underwood et al. conducted experiments on rats and confirmed that the luminescence of larvae has a warning effect on mice.

Scientists have studied the light-emitting organs of fireflies and found that the main substances in the light-emitting cells of fireflies are luciferin and luciferase. The fluorescein in the luminescent cells of fireflies is consumed when they emit light. But don't worry, it has a way to replenish energy, and it is supplemented with the high-energy compound adenosine triphosphate.

Fluorescein is extremely sensitive to adenosine triphosphate, and after each luminescence, as long as a little bit of adenosine triphosphate is added, the fluorescence can be regenerated.

The life of a firefly goes through four stages: egg, larva, pupa and adult. Fireflies are divided into male and female, the female firefly crawls in the grass, and the male firefly flies in the night sky.

The larvae of fireflies love to eat snails and snails. The snail is the ** of the schistosome, the snail damages the crops, and the firefly specializes in destroying these pests, so it is a friend of humans.

Biology has always been the object of human learning and imitation, and many human teachers have gathered in the biological world, and a new discipline has emerged - biomimicry. Firefly is one such teacher.

Fireflies can directly convert chemical energy into light energy, and the conversion efficiency is up to 100, while the luminous efficiency of ordinary light bulbs is only 6. So people imitated the luminescence principle of fireflies and made a cold light source. The cold light source is a light source that emits light through chemical energy and biological energy, which converts almost all the energy into visible light, which can increase the luminous efficiency by more than ten times and greatly save energy.

The physiological structure of fireflies is very special, the end of its abdomen is filled with many phosphorus-containing luminescent matter and luminescent enzymes, which will emit a faint light on the part of the firefly's abdomen. The bright light emitted by fireflies is mainly used to send signals, and fireflies are used in this way for courtship, vigilance, trapping, etc.

We all know that fireflies emit light, but the light it emits is not used for lighting as people think; The fluorescence they emit is more often used for verbal communication and the transmission of information. It may be that the light source is an urgent need for us humans, but it is not a need for life for animals; Because they have long adapted to the dark environment in the long process of evolution, and can move freely in the dark environment. So for fireflies, the light emitted by their tails is not used for lighting, but for signaling, just like our human language.

To know if the light emitted by fireflies is used for lighting, we need to understand why the tails of fireflies emit light. Among the hundreds of millions of insects in nature, only fireflies can emit light, all because of the special structure of firefly physiology. It turns out that there are a lot of phosphorus-containing luminescent substances gathered on the tails of fireflies, just like the glow sticks we saw at the concert.

Moreover, fireflies themselves are more adaptable to the dark, and do not need to rely on tail light to illuminate themselves.

After scientific investigation and research, it has been found that the light emitted by the tail of fireflies is not used for lighting, but for mutual information exchange and transmission. These glowing tails, just like our human language, emit rays of light of different frequencies and brightnesses to convey signals of courtship and danger; At the same time, they can also use these "signal lights" to facilitate communication between them and their peers.

Of course, in addition to the benefits of fireflies shining on themselves, it can also bring many beautiful scenes to us humans; Some people have long used fireflies to confess or use them as lanterns, which can be regarded as another function of fireflies to emit light! In the past, some people caught fireflies in the mountains and forests for profit, and then sold them to make money; Gathering a large number of fireflies together to make lanterns is a beautiful sight, but it becomes a disaster for fireflies.

The light emitted by fireflies is a communication tool, and by emitting light, they can courtship or express their ideas.

It is said that the purpose of firefly light is not only to illuminate, but also to courtship, communicate, warn, display and regulate the population.

What is the role of the light emitted by fireflies other than to lead the way for small ants and to give impetuous lighting to work?

The efficiency of fireflies is very high, and almost all chemical energy can be converted into visible light, which is several times to dozens of times the efficiency of modern electric light sources. Because the light source comes from chemicals in the body, the light emitted by fireflies is bright but has no heat, and does not produce a magnetic field, so this light is called "cold light".Since the light of fireflies does not radiate heat, physicists believe that this is an ideal light, because when something glows, it also generates heat, such as a lit candle.

Another example is when the light is turned on and the bulb is hot. However, people don't need lights to generate heat, and it would be ideal to create light that doesn't heat up like fireflies. More than 30 years ago, people created a fluorescent lamp (fluorescent lamp) that simulated the principle of firefly light, and basically met this requirement.

With the development of science, the application of fluorescence is becoming more and more extensive. Fluorescent light is used to check the bacterial content of food, fluorescent lights are used for lighting in mines containing explosive gases, indicator lights in ammunition depots, and luminous lights for underwater operations. American biochemists proposed the principle of electron transfer reaction according to the principle and mechanism of firefly luminescence, which can explain corrosion phenomena, photosynthesis, etc., especially the development and utilization of lasers, so he won the Nobel Prize in Chemistry in 1992.

Introduction: Many people see fireflies in their lives and don't know how fireflies glow.

When many people walk at night, they always find some fireflies around, and although the light of the fireflies is not very strong, they can be seen. The reason why fireflies emit light is that there are some substances in the body of fireflies, and these substances can glow at night, and fireflies can also be properly observed when they are seen. Although fireflies have light, but the light of fireflies will not be very strong, at this time if you see fireflies, do not catch fireflies with your hands, to properly protect fireflies, fireflies will often haunt at night, at this time must carefully observe the behavior of fireflies, take a look at the beauty of fireflies.

If you like to go to see fireflies at night, you should also control yourself appropriately, and don't let yourself go to see fireflies at night, which may also cause bad things.

There are many people who are very curious, do not know how fireflies form a luminous phenomenon, fireflies have a luminous substance in the body, and fireflies will glow at night, if you want to observe fireflies, you can also take a proper look at the grass to see if there are fireflies. Don't go to the depths of the jungle at night to look for fireflies, it may also bring some danger to yourself, if some people are more afraid, don't go to the night to look for fireflies, and observe them properly. If you want to see fireflies, you can also choose a comfortable environment to relax, and you must relieve your pressure, which will be very uncomfortable if you are under a lot of pressure.

Some people don't know why they have so much pressure, they should learn to relax appropriately, don't let themselves be stressed often, and choose a good environment to give themselves a relaxed state.

The main reason is that the body of fireflies is relatively special, and secondly, because they will keep flying, and then a certain change will occur, resulting in luminescence.

Fireflies are insects that emit light due to their luminescent devices on their tails. Fireflies only glow when they are courting. It is common in the summer.

Fireflies mainly pass through the light cells in the body, and there is a combination of two chemicals, so that they can emit light, and it is necessary to understand the principle of this.

Fireflies are insects that contain chemicals in their bodies that emit a distinctive green or dull yellow glow, a phenomenon known as bioluminescence or biofluorescence. The principle of fireflies' luminescence is to catalyze the masking fluorescein in the body through oxidases, resulting in a chemical reaction that emits light when excited.

The glow of fireflies brings a lot of fun and good memories to humans. The nocturnal fluttering and flickering of fireflies makes people feel mysterious and romantic, especially in the ruined summer nights, and the flying of fireflies often becomes a beautiful sight for people to go out for walks, camping and picnics. In addition, fireflies are also an ecological marker, and their presence represents the health and balance of the ecosystem.

Therefore, fireflies are also considered to be an important part of biodiversity and are of great significance to the protection of the natural environment and ecosystems of human beings.
