Etymology

Blend of Ancient Greek καιρός (kairós, “advantage; profit”, noun) + English pheromone, coined in the 1970 article “Allomones and Kairomones: Transspecific Chemical Messengers” by the American geneticist William Lacy Brown, Jr. (1913–1991), the German-American ecologist and entomologist Thomas Eisner (1929–2011), and the American ecologist Robert Harding Whittaker (1920–1980) which was published in BioScience: see the quotation.
