Pyrethroids alter sodium channel gating in honeybee olfactory receptor neurons

International audience; Social structure in a domestic honeybee colony relies on inter-individual. chemical communication. Chemical communication is mediated. by odors and pheromones detected by olfactory receptor. neurons (ORN) localized in antennae. The Colony Collapse Disorder. (CCD) has been described in many countries around the world. and one of its main symptoms is the desertion of the hive by adult. worker bees, leaving the queen with brood and a small number of. young bees only.
