Hypothesis
Do waggle dancers produce and release chemical compounds that distinguish them from other foragers?
Conclusion
Waggle-dancing honey bees produce a unique scent that increases the number of foragers leaving the hive.
Supporting Evidence
- Waggle dancers produce four hydrocarbons that distinguish them from nondancing foragers.
- Injection of the waggle-dance scent increased the number of bees exiting the hive.
- Nondancing foragers produce these compounds in only minute quantities.
- More vigorous dancers tended to emit higher amounts of the compounds.
Takeaway
Honey bees that dance to show where food is also release a special smell that helps other bees find the food faster.
Methodology
The study used solid-phase microextraction and gas chromatography coupled with mass spectrometry to analyze the chemical compounds produced by waggle dancers.
Limitations
The study was conducted in controlled conditions, which may not fully replicate natural foraging environments.
Participant Demographics
Honey bees (Apis mellifera L.) from two colonies.
