Although the vomeronasal organs , which are responsible for pheromone detection and brain function in animals , are thought to be vestigial and inactive in humans , research indicates we do communicate with chemicals .
This paper summarized chemical structure characters of semiochemicals in scarabs , and reviewed the unique reciprocal role of chiral sex pheromones as agonist antagonist in chemical communication in scarabs and biosynthesis of sex pheromone .
