Artificial Light Keeps Mosquitoes Biting Late into the Night

[Samuel S. C. Rund et al., Artificial light at night increases Aedes aegypti mosquito biting behavior with implications for arboviral disease transmission]Duffield cared less about whether his colleague would be delicious—that was obvious. What he really wanted to know was—like humans kept awake by the light of their cell phones—would artificial lighting keep mosquitoes up and biting deep into the night? So Duffield and his colleagues created an experiment: they’d monitor the biting behaviors of mosquitoes who had been exposed to pulses of artificial light throughout the night. Schwing: The next step is to look at how different species of mosquitoes respond to different kinds of light. Since some are day feeders, it raises the question of whether artificial light at night would affect them at all.
