Artificial light abnormally increases mosquito biting behavior at night in a species that typically prefers to bite people during the day, according to research from the University of Notre Dame that was published in The American Journal of Tropical Medicine and Hygiene.
Increased biting by Aedes aegypti mosquitoes, which normally fly and bite in the early morning and during the afternoon, highlights the concern that increasing levels of light pollution could impact transmission of diseases such as dengue fever, yellow fever, chikungunya and Zika.
“This is potentially a very valid problem that shouldn’t be overlooked,” said Giles Duffield, associate professor in the Department of Biological Sciences, who is also affiliated with the Eck Institute for Global Health and the Neuroscience and Behavior Program. Unlike other species that may emerge from the forest to feed on humans and animals, Aedes aegypti evolved with humans and prefers to feed on them.
