Altering Social Cue Perception Impacts Honey Bee Aggression With Minimal Impacts On Aggression-Related Brain Gene Expression, James W. Harrison, Joseph H. Palmer, Clare C. Rittschof

Entomology Faculty Publications

Gene expression changes resulting from social interactions may give rise to long term behavioral change, or simply reflect the activity of neural circuitry associated with behavioral expression. In honey bees, social cues broadly modulate aggressive behavior and brain gene expression. Previous studies suggest that expression changes are limited to contexts in which social cues give rise to stable, relatively long-term changes in behavior. Here we use a traditional beekeeping approach that inhibits aggression, smoke exposure, to deprive individuals of aggression-inducing olfactory cues and evaluate whether behavioral changes occur in absence of expression variation in a set of four biomarker genes …
