Scheiner lab - Behavioral biology of the honeybee

Honey bees have been model organisms in behavioral biology for many decades. With their unique behavioral diversity, they offer ideal conditions for studying basic mechanisms of decision making and behavioral control. Since honey bees are found all over the world, we can use them to investigate the adaptation of behavior and their molecular basis. Our research focuses on social behavior, learning behavior and the adaptation of honeybees to their respective habitats.
We also study honeybees' taste perception and metabolism.

In addition to these questions, we are interested in the effects of plant protection products on the behavior of honeybees and are investigating new and sustainable ways to protect the bees from the varroa mite.
