I am interested in the molecular mechanisms underlying the control of behavior in honey bees. I am particularly keen to understand how the complex division of labor is regulated in a honey bee colony. Using up-to-date molecular biological methods (for example quantitative real-time PCR), biochemical methods (immunocytochemistry, Westernblots) and a variety of behavioral assays (quantification of gustatory, visual and olfactory responsiveness, learning assays, long-term video monitoring, behavioral manipulations) we investigate the functions of selected receptors for biogenic amines and cGMP-dependent protein kinase in honey bee behavioral plasticity.

Current research projects are:

  • Role of cGMP- dependent protein kinase in honey bee division of labor
  • Functions of octopamine and tyramine receptors in behavioral decisions of honey bees
  • Role of octopamine in regulating gustatory responsiveness and non-associative learning processes in fruit flies
  • Age-dependency of honey bee learning
  • Gustatory responsiveness and learning in honey bees
