Morphofunctional Changes of Ovarioles of the Blood-Sucking Mosquito (Diptera, Culicidae) during Oogenesis. 2. Abortive Oogenesis
Abstract
In a previous report examined the normal oogenesis of blood-sucking mosquitos using the example of 15 species, as well as the methods of its supravital study. This work presents data on abortive oogenesis in these same species, obtained with the application of analogous methodologies. Abortive oogenesis is a process of degeneration of the follicles in individual ovarioles, and occurs parallel with normal oogenesis in other ovarioles of the ovary. At the given ovariole cycle, as a result of degeneration, so-called extasias are formed instead of the ovum. Depending on the character and time of feeding of the female, we may distinguish 3 variants of degeneration: Pregonotrophic, agonotrophic, and gonotrophic, and progonotrophic (7), agonotrophic (5) and gonotrophic (5) extasia. Moreover, extasia may be present in the ovarioles which we have called vestigial (8) and aberrant (9). The former represent any of the indicated forms of extasia pushed under the ovariole membrane by the emerging egg. Aberrant extasia are formed with an anomalous condition of the ovarioles. Reprints.
