  • Title: Chemosterilant (apholate)-induced ultrastructural changes during oogenesis in Aedes aegypti.
    Author: Mathew G, Rai KS.
    Journal: Cytobios; 1975; 12(45):45-56. PubMed ID: 126140.
    Abstract:
    The effect of chemosterilant, apholate, on-oogenesis has been studied in Aedes aegypti. Treatment of larvae to 20 ppm of the chemical induced ultrastural changes in the presumptive and primary follicles of the adult ovary. These changes comprised condensation of chromatin, disruption of nuclear envelope and extensive degeneration as evidenced by numerous myelin figures and residual bodies. In some primary follicles, where cellular degeneration was restricted to epithelial cells, no arrest in development was observed. However, in comparison with controls, these follicles also were retarded. Larval treatment with 30 ppm apholate completely supressed ovariolar development. High incidence of autophagy was observed in tissues at both dose levels.
