Pheromones

Pheromones

(i) They are chemicals used for communication amongst individuals of the same species.

Pheromones are produced by exocrine glands and are transmitted to other members

through air or excrements (e.g., urine in dogs).

(ii) Pheromones invoke a specific response in other members like recognition, attraction, warning, etc. Bombykol is sex attractant pheromone produced by female silkworm moth, which is received by male antenna several kilometers away.

(iii) Ant trail is due to pheromone. Queen Bee is recognized by workers due to release of

9-oxydecenoic acid by it. Dormitory effect is also believed to be due to pheromones
