| Abstract: | Administration of precocene II (6,7-dimethoxy-2, 2-dimethyl chromene) to freshly emerged virgin female flies of S. ruficornis adversely affected the development and differentiation of ovarian follicles leading to a number of morphological abnormalities. Precocene treatment resulted into suppression of development of egg chamber, differentiation of follicular epithelium, degeneration of nurse cells, growth of oocyte and uptake of yolk granules by oocytes. The results suggest that precocene induced effects are due to deficiency of juvenile hormone. |
