Observing a feeding behavior response called proboscis extention reflex (PER) of the blowfly, Phormia regina, we showed that the insect was sensitive to 5'-GMP (guanosine monophosphate) and 5'-AMP (adenosine monophosphate) but not to 5'-IMP (inosine monophosphate) and MSG (monosodium glutamate). Although MSG itself did not induce the PER of the fly, it remarkably enhanced the PER to sucrose. Thus, the phagostimulative properties of the umami substances for the blowfly are different from those for human in detail. However, we still consider that the blowfly is an available model animal for studies on umami taste reception and taste enhancing effects of umami substances at the molecular level.
