Effect Of Light Pollution On Insects

Nowadays the types of pollution have increased in the world. Earlier, noise pollution was included in man-made pollution and now light pollution has also been included in it. Human beings have created many types of artificial bulbs for their convenience. But the increasing glare in the cities has taken the form of light pollution.  It is probably not that dangerous for humans, but this light pollution is having an effect on the life of insects.

Research on light pollution

Different types of insects are attracted to light. As soon as they go in front of a light, their eyesight starts to change. According to a study by researchers from the University of Exeter, UK, the colors and intensity of this pollution have had complex and unpredictable effects in the eyes of insects. This pollution can also be a message of some new danger coming in the future. 

The attraction of insects to light and being preyed upon by other birds are all well-known phenomena.  But to find out the effect of light on their vision, the researchers put about 20 types of light on the eyes of insects and birds of their prey.

A strange thing also came to the fore in this study.  The vision of the Elephant hawk moth, where being obstructed in many types of light, is also increasing in a specific type of light.  In addition, birds that hunted elephant hawkmoths were found to have improved illumination for each type of light. 

The artificial light that has been invented for human convenience lacks the blue and ultraviolet ranges. And these blue and ultraviolet categories are helpful in determining the vision ability of insects.  Such conditions impede the insects’ ability to see in many colors. This makes it difficult for insects to hide from their predators.  That’s why researchers have called for a sensitive approach to limit the amount and capacity of light.
