单词	pheromone
释义	pheromone /ˈfɛrəməʊn / noun Zoology A chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behaviour or physiology of others of its species.Once an enterprising hornet scouts out a bee colony, it marks the nest with a type of bodily chemical substance called a pheromone.... Bluntnose minnows probably release chemicals called pheromones when they are alarmed. In most species, the pheromones act as attractants and sexual stimulants. Derivatives pheromonal /fɛrəˈməʊn(ə)l/ adjective ... Red-backed salamanders, Plethodon cinereus, use territorial advertisement in the form of agonistic displays and pheromonal scent marking as a mechanism for intraspecific interference competition. Thus, females that attempted to avoid courtship (as predicted under the hypothesis of sexual conflict) might be able to do so by selecting sites with fewer pheromonal cues from males. Urine signals, excreted through nephropores located near the base of the antennae, are a likely source of pheromonal cues in decapods. Origin 1950s: from Greek pherein 'convey' + hormone.
