kairomone, n. Biol.|ˈkaɪrəʊməʊn|
[f. Gr. καιρό-ς opportunity, advantage + -mone after pheromone n.]
A chemical secreted and released by an organism which, when detected by an organism of another species, evokes a response which adaptively favours the latter.
1970W. L. Brown et al. in Bioscience XX. 21/1 Organisms also produce a wide range of substances that act as stimulants, inhibitors, or behavioral cues for species other than their own. Among these substances, we propose to designate two major functional groupings by the terms allomone and kairomone, chosen as intentional parallels to the term pheromone. Ibid. 21/2 A kairomone is here defined as a transspecific chemical messenger the adaptive benefit of which falls on the recipient rather than on the emitter. 1971Nature 13 Aug. 484/1 Work is in progress..making use of the parasites' ovipositional response as a bioassay for the kairomone. 1978Nature 27 Apr. 817/2 I[ps] avulsus..aggregates in response to ipsdienol and (S)-(-)-ipsenol, apparently the combination of a pheromone and a kairomone. 1989Ann. Entomol. Soc. Amer. LXXXII. 656/1 In most parasitoid species investigated to date, host-emitted kairomones figure prominently in the foraging process. |
