Definición de kairomone en inglés:
A chemical substance emitted by an organism and detected by another of a different species which gains advantage from this, e.g. a parasite seeking a host.
- Unlike a pheromone, which involves only one species, kairomones are chemicals emitted by one species - in this case pears - that attract and benefit another, such as codling moths.
- Thus, natural selection should favor parasitoids that utilize as kairomones only the chemicals that uniquely and reliably identify potential hosts.
- According to Torr, ‘Tsetse use host kairomones to locate their hosts by a process termed ‘odour-mediated upwind anemotaxis’.
late 20th century: from Greek kairos 'advantage, opportunity', on the pattern of pheromone.
