Moth uses fine tuning for odour resolution
T. C. Baker1, H. Y. Fadamiro1 & A. A. Cosse1
Abstract
Male moths, when responding to their species' blend of sex pheromones, cease their upwind flight when additional compounds are added to the mixture. Often these behavioural antagonists are the pheromone components of sympatric species that emit similar pheromone blends, and thus may function to prevent mating with females of the wrong species. Antagonists must be emitted from the same point source as the pheromone blend to be optimally effective1, 2, 3, 4, suggesting a fine discrimination between the occurrence of pheromone and antagonist.
