Nutrition, Aging and Reproduction In The House Fly, Musca Domestica L., And The Histology and Histochemistry of the Related Changes in the Ovaries and Fatbodies

Abstract

<p> This research was designed to gain a better understanding of the relationships between nutrition, aging and oogenesis. Cohorts of 1800 inbrod, adult house flies were maintained on various undefined and chemically defined diets. From these flies samples for histology were removed periodically, and the rest were analyzed for their survival and their ability to develop and lay viable eggs. The survival of the females was more affected by nutrition and other factors than that of the males. In females fed sugar water, oogenesis was arrested at an early stage, but survival was lower than on a milk diet. From adult emergence until the completion of one or more ovarian cycles, the larval and adult fatbodies and the ovary were compared as to their histology, histochemistry and cytology.
