Light pollution may extend mosquitoes’ biting season

Published on April 13, 2023

Imagine you’re eagerly anticipating a long winter’s rest, but then someone turns on a bright and flashy disco ball in your bedroom. Suddenly, your plans are foiled, and you find yourself staying awake longer than expected. Well, that’s exactly what happens to mosquitoes when they encounter urban light pollution. A recent study suggests that artificial lights in cities disrupt the mosquitoes’ dormant period, called diapause, and extend their biting season. While it may seem like good news that the disease-carrying pests might not survive the winter, it also means they continue feasting on humans and animals well into the fall. The impacts of this extended biting season could have significant consequences for the transmission of diseases like West Nile virus.

Scientists now need to further investigate how light pollution affects mosquito populations and develop strategies to minimize its effects. To learn more about this fascinating research and its implications for public health, delve into the full article!

A new study’s finding that urban light pollution may disrupt the winter dormancy period for mosquitoes that transmit West Nile virus could be considered both good news and bad news. The good news is that the disease-carrying pests may not survive the winter if their plans to fatten up are foiled. The bad news is their dormancy period, known as diapause, may simply be delayed — meaning they’re biting humans and animals longer into the fall.
