Artificial light at night (ALAN) is a major factor in global insect decline. In a paper published today in
Insect Conservation and Diversity, Smithsonian Conservation Biology Institute (SCBI) scientists and partners found that using amber-colored filters to remove the blue spectra of light from warm white LED (light-emitting diode) lamps drastically reduces insect attraction to nocturnal lighting in a tropical forest. This is the first study to validate quantitative predictions of how lamp color affects insect attraction and provide clear recommendations to mitigate the negative impacts of ALAN on wildlife in rainforest ecosystems. While many people aren t necessarily fond of bugs, their importance in our everyday lives is indisputable, said Jessica Deichmann, first author and research scientist with the Smithsonian Conservation Biology Institute and the Smithsonian Conservation Commons Working Land and Seascapes Initiative.
