Enantiomers of chemical signals are important in insect olfactory communication.  Both host produced chemicals and insect pheromones may be emitted as chiral signals.  Discrimination of these chemical signals by olfactory receptor neurons (ORNs) involves molecular components of the peripheral olfactory system including soluble proteins such as odorant binding proteins (OBPs) and membrane-bound odorant receptors (ORs).  The relative importance of OBPs, ORs and other components of the peripheral olfactory system in the discrimination of enantiomers by insects will be discussed.
