Definition
Meaning and Definition
A chemical substance secreted by an organism which induces a response in a member of another species that is beneficial to the emitter.
In biology and ecology, an allomone is a type of semiochemical (signalling chemical) that crosses species boundaries, providing an adaptive advantage to the organism producing it. It is contrasted with kairomones (beneficial to receiver) and synomones (beneficial to both).

FAQ
Frequently Asked Questions
A pheromone is a chemical signal used for communication within the same species (intraspecific). An allomone is used between different species (interspecific) and benefits the emitter.
Yes. The skunk's spray is a classic example. It is a defensive chemical (an allomone) released against potential predators from a different species, benefiting the skunk.
No, it is a highly specialised term confined to scientific fields like ecology, entomology, and chemical ecology.
The main types are: Pheromones (intraspecific), Allomones (benefit emitter, interspecific), Kairomones (benefit receiver, interspecific), and Synomones (benefit both emitter and receiver, interspecific).
A chemical substance secreted by an organism which induces a response in a member of another species that is beneficial to the emitter.
