VARIATIONS IN FREE AMINO ACID POOL DURING AGING ADULT IN SODIUM HYPOPHOSPHITE FED MUSCA DOMESTICA NEBULO F. (DIPTERA : MUSCIDAE)

The concentration of amino acids in one day old males and females of Musca domestica is very high which shows a sharp decline upto 6 days of age. This fall in FAA concentration concides with the process of oviposition in females when yolk proteins are deposited into the maturing oocytes and the process of oviposition starts. Similarly decrease in FAA concentration in males is concomitant the process of spermatogenesis. During the active reproductive period the FAA remains high upto day 10. However, it declines as the post reproductive period approaches. During the midlife of the adults i.e. about 15 days, the FAA once again registers an increase to a considerable level. On SHP feeding the FAA content decreased in both the sexes. It reflects an increase in protein synthesizing capacity, as compared to the control group. The changing trend is SHP fed cohorts is found to be analogous to the control cohorts revealing that SHP does not interfere with the biological expression of different phases of life cycle.
