Sleep, mosquitos

Mosquitos staying active longer

“A new study published in the Journal of Insect Physiology suggested that artificial lights are disrupting mosquitos and delaying their dormancy, meaning that they stay active longer. Mosquitos rely on shortening daylight in the fall as a cue to enter a dormant state, but artificial light appears to keep the bloodsuckers up and active. In an experiment, mosquitos kept under light in September entered diapause at a quarter the rate of those kept in the dark, and while every mosquito in a dark enclosure had gone dormant by October, 59 percent of those exposed to light stayed active.”
