Alarm pheromone induces stress analgesia via an opioid system in the honeybee

Mostrar todas las versiones(2)

Changes of the stinging response threshold of Apis mellifera a scutellata were measured on foragers fixed on a holder and stimulated with an electric shock as a noxious stimulus. The threshold of responsiveness to the noxious stimulus increased when bees were previously stimulated with isopentyl ace...
