Social insect olfaction research
Overview
In July 2026 researchers at the University of Illinois reported that honey‑bee larvae experience a temporary loss of odor detection. The study showed a sharp reduction in the olfactory coreceptor gene ORCO during the larval stage, while taste receptors remained functional, indicating a developmentally regulated sensory gap that relies on nurse bees for nourishment and protection.
A few weeks later, a separate investigation examined odor learning in bumblebee workers. By substituting the queen’s natural pheromone with a novel synthetic odor, the researchers demonstrated that workers could be trained to treat the new scent as a queen signal. This finding suggests that odor recognition in social insects is not solely hard‑wired but can be shaped by experience and social context.
Together, the two studies expand understanding of how social environments influence olfactory systems across different bee species, highlighting both developmental regulation and learning flexibility in insect scent perception.
