found in insects photoreceptor cells it allows them to perceive different wavelengths of light, such as infrared and ultraviolet. Thanks to these abilities, they use light for purposes such as determining direction, finding food, and protecting themselves from danger.

This is what people perceive differently. wavelengths They determine their direction at night. Artificial light such as street lamps prevent insects from using their abilities and insects are no longer able to navigate in the dark.

Aside from photoreceptor cells and the wavelength of light, another possible reason is believed to be insects’ inability to use sunlight and moonlight.

With this natural light, insects determine their direction, the distance between the light source and the light source by artificial light. angle of light loses these skills if it changes significantly.

Insects glow from natural light sources with a fixed angle But since artificial light scatters light in all directions, it causes insects to maintain a fixed angle. As they fly, their angles to the light source narrow and they begin to orbit around artificial light sources.

To reduce the effects of this situation, which negatively affects insects, you can use yellow shades instead of blue light.

Because while the blue light surprises the insects more yellow light has little effect. It is also a better option for humans because yellow light is more economical. According to a study of 8887 insects and spiders, light bulbs attract the most insects.

Fluorescent lamp, halogen lamp, cold color temperature LED lamp and yellow lamp respectively follow incandescent lamp. The lamp type that attracts the least insects are LEDs. in your house yellow LED light Using it, you can get rid of the infestation of insects and please them.

“Phototaxy”, which is defined as the positive or negative response of living things to light, may also be one of the answers to this question.

“Photo” means “light” in Greek and “tax, taxo” means “arrangement”. Insects with positive phototaxis such as moths and flies turn to the source when they see a light source, such as cockroaches. negative phototaxis Insects, on the other hand, tend to flee when they see light.

Most naturally occurring cyanobacteria do positive phototaxis because they need light to photosynthesize. in insects brought by evolution Positive or negative phototaxis arises for several reasons. In addition to phototaxis, there are also taxi methods such as chemotaxis, hydrotaxis, gravitaxy, aerotaxis and electrotaxis.

Insects can sometimes get on your clothes for a similar reason.

Some flowers that see insects as their “main food” reflect ultraviolet rays, attracting them. Patterns on your clothes from the rays reflected by some colors. the inside they perceive as a flowerThey can land on you.

Now you know what the possible causes are when you see a swarm of insects swarming in the light. Stick to the science.
