Deep dives
Bees release a banana-like smell when angry
Bees emit a banana-scented pheromone when they are distressed or alarmed, which is caused by isomyl acetate. This chemical happens to be the same one responsible for banana flavoring. Beekeepers have reported smelling a distinct banana odor when bees are agitated or angry, alerting beekeepers to the bees' state.
Bees use pheromones for communication
Bees use pheromones extensively for communication within the hive. Queen bees release pheromones to indicate their presence and reproductive status. Worker bees release distress signals that contain isomyl acetate, which smells like bananas, when they are in trouble, signaling other bees in the hive to be on high alert.
Pheromones in insects beyond bees
Insects use pheromones for various purposes beyond bees. Dung beetles share a pheromone called isosomal acetate, which smells like star anise, for communication. For queen bees, specific pheromones signal mating status and govern hive dynamics, while ants may emit distinct pheromones with unique scents.
Battle of libraries and parchment innovation
The rivalry between the Library of Alexandria and the Library of Pergamum led to the ban on papyrus exports by King Tolmi V, sparking the creation of parchment by the Pergamites. Parchment, made from animal skin, revolutionized book production, offering a more efficient alternative to papyrus scrolls.
Innovative uses of pheromones
Pheromones play unique roles in insect behaviors, such as aiding in queen bee selection and communication within bee colonies. Humans have also harnessed the power of pheromones in detecting bed bugs in hotels, using specialized traps with cameras and pheromones to identify and address infestations.
