The neural basis for insect pheromonal communication

Insects rely on chemosensory signals to drive a multitude of behavioral decisions. From conspecific and mate recognition to aggression, the proper detection and processing of these chemical signals - termed pheromones - is crucial for insects' fitness. Although the identities and physiological impacts of diverse insect pheromones have been known for many years, how these important molecules are perceived and processed by the nervous system to produce evolutionarily beneficial behaviors is still mostly unknown. Here we present an overview of the current state of research into the peripheral and central nervous system mechanisms that process and drive behavioral responses to diverse pheromonal cues.
