Olfactory responses (EOG: electro-olfactogram) of 11 species of teleost (five Cypriniformes and six non-Cypriniformes) to F-prostaglandins (PGF2 alpha, 15-keto-PGF2 alpha, 13,14-dihydro-15-keto-PGF2 alpha) were examined. All the Cypriniformes showed distinct EOG responses to F-prostaglandins at 10(-7) M. By contrast, non-Cypriniformes with the exception of ayu, Pleccoglossus altivelis, showed responses to 10(-7) M F-prostaglandins of < 22% of that to 10(-5) M L-serine, and they were anosmic to 10(-8) M F-prostaglandins. These results indicate that F-prostaglandins are potent chemical stimulants in Cypriniformes, and suggest that F-prostaglandins may be commonly used as sex pheromones in Cypriniformes, whereas they seem not to have pheromonal functions in most non-Cypriniformes examined.
检测了11种硬骨鱼（5种鲤形目和6种非鲤形目）对F-前列腺素（PGF2α、15-酮-PGF2α、13,14-二氢-15-酮-PGF2α）的嗅觉反应（EOG：电嗅图）。所有鲤形目在10⁻⁷ M时对F-前列腺素均表现出明显的EOG反应。相比之下，除香鱼（Pleccoglossus altivelis）外的非鲤形目对10⁻⁷ M F-前列腺素的反应小于对10⁻⁵ M L-丝氨酸反应的22%，并且它们对10⁻⁸ M F-前列腺素无嗅觉反应。这些结果表明F-前列腺素在鲤形目中是强效化学刺激物，并表明F-前列腺素可能在鲤形目中普遍用作性信息素，而在大多数所检测的非鲤形目中它们似乎没有信息素功能。
