What are chemicals with odor produced by animals that have specific effects on the same species called?

The correct term for chemicals with odor produced by animals that have specific effects on individuals of the same species is pheromones. Pheromones play a critical role in communication among members of the same species, influencing behaviors such as mating, alarm signaling, and territorial marking. These chemical signals are vital for reproduction and social organization in many animal species, including insects and mammals.

Pheromones differ from other chemical signals, such as hormones, which are produced within the body and primarily act on the individual that secretes them, often affecting physiological processes. Allomones, on the other hand, are chemicals that benefit the sender and affect the behavior of a different species, not the sender's own. Neurotransmitters are also distinct because they are chemicals that transmit signals between neurons and play roles within the nervous system rather than serving as external signaling mechanisms for interspecies communication. Understanding these definitions helps clarify the unique function that pheromones serve in social and reproductive behaviors in the animal kingdom.
