The regulation of blood sugar in the aging blowfly, Phormia regina.

The adult blowfly, Phormia regina, reveals a substantial homeostatic capability when examined for its ability to regulate externally administered additions to its blood sugar. As well, results of experiments done at intervals throughout the entire adult life of the fly show that there is no decrease over time in the efficiency of operation of the complex system involved in the control of the blood sugar level. Taken together with other independent investigations of Phormia metabolism, the research indicates that this animal, in contrast to the rat, possesses a number of physiological systems which embody regulatory processes that may be only marginally subject to the normal "aging" process.
