Comparative study by electrophysiology of olfactory responses in bumblebees (Bombus hypnorum andBombus terrestris)

Abstract
Electrophysiological data (EAG) were recorded on adult bumblebees stimulated with floral and/or pheromonal pure odorants at different concentrations. The responses of queen, worker, and male bees are compared and the sensitivities of these insects to the pure odorants tested are discussed.
