A few days ago, the announcement of the Nobel Prize winners in 2014 gave LEDs enough public opinion, but a new study found that this may be bad news for insects. Moths, flies, and other insects are more susceptible to the spectrum of led light than the yellow glow from a sodium vapor bulb. A recent study published in the Journal of Ecology Applications shows that traps near led capture more than 48 insects than traps near sodium vapor bulbs. Overall, the researchers captured and identified more than 20,000 worms, including moths and flies. This attraction is fatal, it shuts off the insect's ability to navigate and exposes them to predators. Greater ecological effects may include damage to the food chain. One point that should be of particular concern is that LED lights near the port can attract flying pests that are accidentally brought in by ships, such as gypsy moths, an invasive species that can destroy forests. Unfortunately, these tests show that simply distorting the spectrum of the LED does not reduce their attractiveness to insects. It is possible that some filters, or a combination of red, green, and blue led, will reduce the visual appeal, but may increase cost and energy consumption.
