LED function: a trap insects

The day before the 2014 Nobel Prize Winner Announced LED (LED) gained critical acclaim, but a new study found that this could be bad news for the insects.

Moths, flies and other insects are more likely to be attracted by the LED ray spectrum than the yellow halo of the sodium vapor bulb. A new study, published in the Journal of Applied Ecology, found that traps near led capture more than 48% of the insect's traps near the sodium vapor bulb.

Overall, the researchers captured and identified more than 20 thousand bugs, including moths and flies. This attraction is deadly, it can turn off the insect's ability to navigate and expose them to predators. A greater ecological effect could include the destruction of the food chain. One point of particular concern is that the LED lights near the port can attract flying pests, such as the gypsy moth (pictured), an invasive species that destroys the forest.

Unfortunately, these tests show that simply distorting the LED spectrum does not reduce their attractiveness to insects. Some filters, or combinations of red, green and blue LED, may reduce visual appeal, but may increase costs and energy consumption.
