During the 2017 total solar eclipse, researchers captured a surprising phenomenon: bees stopped buzzing as Earth fell into complete darkness. The study, led by Candace Galen at the University of Missouri, found that bees did not use the unusual darkness as a cue for night and instead flew during periods of reduced light.
A new study led by James Crall at Harvard University found that exposure to neonicotinoid pesticides has profound effects on a host of social behaviors in bees, including reduced nursing of larvae and decreased social interaction. The study also showed that pesticides impair bees' ability to regulate temperatures inside the nest.
Exposure to neonicotinoids like imidacloprid disrupts bee colony growth by reducing worker activity, feeding and larval care. This results in impaired thermoregulation, increased mortality and reduced colony sizes.
