The kairomone improves the fitness of the recipient and in this respect differs from an allomone (which is the opposite: it benefits the producer and harms the receiver) and a synomone (which benefits both parties).
A cairomona mellora a fitness do receptor e nese sentido diferénciase dunha alomona (que fai o contrario: beneficia ao produtor e dana ao receptor) e a unha sinomona (que beneficia a ambas as partes).
