What to know about Bumblebees can learn to associate new smells with their queen

Researchers at Penn State found that bumblebees can learn to associate new floral scents with their queen, suggesting that social insect behavior is more flexible than the traditionally held 'hard-wired' view. The study also explored how these learned scents affect worker reproduction, finding that the presence of brood may influence the bees' physiological response to the odor.

What happened

Bumblebees can learn to associate new smells with their queen Sadie Harley Scientific Editor Robert Egan Senior Editor Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's…

Why it matters

For the study, published in the journal Communications Biology, the researchers treated buff-tailed bumblebee queens daily with one of two different floral scents as they built their colonies.

Common ground

Later, the researchers gave worker bees who grew up exposed to one of these scents as they tended to the queen a choice between the floral scent applied to their queen and a new, different scent they had never encountered before.

Perspective signals

Claim 2: “However, when the brood was present, the smell of the queen made workers lay more eggs”
CORROBORATED
Cultivar Magazine explicitly states that learning the queen-associated scent 'influenced egg laying in the presence of brood'. Wikipedia also confirms that egg laying in B. affinis is typically suppressed by the queen, supporting the context of the claim.
