In moths, pheromones are detected by a compound nose (Steinbrecht, 1999), i.e. a network of hair-like sensilla distributed over the surface of the antennae. For example, in the wild silkmoth, Antheraea polyphemus, each male antenna...

In 1981, the pheromone binding protein (PBP) and sensilla esterase (SE) of Antheraea polyphemus were identified [44] and in 1985 a new model for pheromone detection was proposed, in opposition to the previous model. In this model, PBPs transported pheromone to receptor proteins (replacing pore-tubules in this role) and SE rapidly inactivated pheromone by enzymatic degradation [45]. PBPs have become established as only a subclass of a much larger family of insect OBPs that are represented at least throughout the neopterous insects, from cockroach to honeybee. 

Fig. 3.1. Antenna of the male satumiid moth Antheraea polyphemus. Upper panel Schematic view of the antenna. Each antennal stem segment has four side branches. Lower panel Two antennal segments enlarged with different types of sensilla. The numerous, long olfactory hairs contain two or three receptor neurons responding to two or three components of the female pheromone.
