How do bugs sense? Insects “smell” with their antennae. Pheromone-binding proteins (PBP) pick up pheromones at pores in the outside of the antenna and carry them through a watery layer to the nerve endings, where they are released. The new NMR results showed that the PBP changes its shape to eject the pheromone molecule.
