Pheromones - Preferred

Concept UI	M0016588
Scope note	Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from other organisms of the same species. Perception of these chemical signals may be olfactory or by contact.
Preferred term	Pheromones
Entry term(s)	Pheromone

Kairomones - Related but not broader or narrower

Concept UI	M0401205
Scope note	Allelochemicals in that the elicited response of the receiver is adaptively favorable to the receiver but not to the emitter. They are sometimes called attractants.
Preferred term	Kairomones
Entry term(s)	Kairomone

Allomones - Related but not broader or narrower

Concept UI	M0401204
Scope note	Allelochemicals in that the elicited response of the receiver is adaptively favorable to the emitter but not to the receiver. They are sometimes called repellents (INSECT REPELLENTS) or deterrents.
Preferred term	Allomones
Entry term(s)	Allomone

Ectohormones - Broader

Concept UI	M0016589
Preferred term	Ectohormones
Entry term(s)	Semiochemical Semiochemicals

Synomones - Related but not broader or narrower

Concept UI	M0401206
Scope note	Allelochemicals in that the elicited response of the receiver is adaptively favorable to both emitter and receiver.
Preferred term	Synomones

Allelochemicals - Related but not broader or narrower

Concept UI	M0397514
Scope note	Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from organisms of a different species . Perception of these chemical signals may be olfactory or by contact. Allelochemicals are subdivided into several groups depending on the response of the receiver and its adaptive effect to the emitter. They can be allomones, kairomones, or synomones.
Preferred term	Allelochemicals
Entry term(s)	Allelochemical
