Now under the night lights in the countryside, why are all kinds of insects basically gone?

Nowadays, the rural environment is particularly polluted, and a lot of chemical fertilizers are used in rural farming, which will affect these insects.

Now that the environment has broken out in various places, there has been a very serious damage to the environment, so this insect is basically gone.

At night, there are also a lot of vehicles in the countryside, and some of the headlights can distract insects.

Small moths, small flies, small mosquitoes, small leafhoppers, little planthoppers, etc. all like lights, especially those smaller midges and gnats, which have strong phototaxis and can easily enter the poorly closed lampshade.

Truly. One of the best parts of traveling is encountering fireflies flying by in the dead of night. So, why do fireflies glow?

How do small fireflies emit light? Let us know and take a look. Why do fireflies shine on summer nights, fireflies find crystal lamps very cute and beautiful.

Fireflies emit a yellow-green light, a cool color that emits less than 1/400,000 of heat. Some say that fireflies glow to find a mate, while others say that fireflies glow to scare enemies. Either way, the "light show" of the fireflies is absolutely enjoyable and memorable as far as the eye can see.

How do fireflies glowSo, why do fireflies glow, and how do they work? Adult fireflies have a glowing organ at the end of their abdomen. Males have two parts, while females have only one.

The luminescent device is filled with phosphorescent substances and luminescent enzymes. Under the transparent epidermis of the luminaire, there is a luminescent layer and a reflective layer, which are covered with reticular trachea and nerves. Fireflies have a chemical called luciferase that glows when it interacts with oxygen.

When a firefly produces luciferase, it's like turning a light bulb switch.

Why fireflies glow one is courtship, and the other is to warn and intimidate enemies. Mating fireflies glow for courtship. Different species of fireflies emit different lights, which naturally isolates them from each other.

Fireflies generally only emit light from male fireflies, while female fireflies do not or do not develop, so male and female fireflies can attract each other and chase each other to achieve the purpose of courtship. Another theory of scaring enemies is that the light emitted by fireflies is meant to scare enemies. Scientists have proven that the glow emitted by firefly larvae is a warning to rats that lizards that eat them will die.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The reason why insects like to fly around lights at night is because of the phototaxis of insects.

Phototaxis is a kind of habit of organisms to move near or far from light, and it is also a kind of biological stress, which is the result of long-term natural selection. Nocturnal insects are mostly very phototaxis, such as nocturnal moths and beetles. Modern research suggests that the phototaxis of nocturnal insects is related to their navigation style.

They usually use the moon as their navigation coordinates and fly not perpendicular to the moonlight, but obliquely; Because the moon is a distant source of light, moonlight is approximately parallel light, and it can fly in a straight line at an oblique fixed angle. The lights will make them mistake it for the moon, but the lights are close to the light source, forming divergent light instead of parallel light, and as a result, the insects still fly at a fixed angle diagonally, and finally fly towards the lights in a spiral asymptote trajectory.

They usually use the moon as their navigation coordinates and fly not perpendicular to the moonlight, but obliquely; Because the moon is a distant light source, the moonlight is approximately parallel light, and it can be judged to fly in a straight line by oblique and fixed angles. The light will make them mistake it for the moon, but the light is a close-up light source, forming divergent light instead of parallel light, and the insect still flies at a fixed angle diagonally, and finally the dug up will fly towards the light in a spiral asymptote trajectory.

Tea small green leafhopper, common phototaxis insect. Turn on the lights at night and you'll be attracted.
