How artificial light slows down the biological clock of mosquitoes and may increase the risk of West Nile virus transmission

Researchers have discovered that artificial outdoor lighting can delay the biological clock of mosquitoes, keeping the insects that transmit the West Nile virus active for longer periods. The study compared mosquitoes raised under common nighttime illumination conditions with other groups to evaluate how artificial light impacts their behavior.

This extension of activity duration could potentially elevate the risk of West Nile virus transmission to humans. The findings highlight the ecological impact of urban lighting on vector behavior and public health safety.
