[Morphofunctional changes in the ovarioles of blood-sucking mosquitoes (Diptera, Culicidae) during oogenesis. I. Normal oogenesis].

Contemporary level of knowledge of morphological specificities of the mosquitos' ovariole development during normal oogenesis is analysed basing on the authors' proper research and literature data. Disputable problems of morphofunctional role of certain ovariole structures are discussed. The paper is illustrated by photos and pictures of ovarioles from the moment of germarium formation to the beginning of vitellogenesis.
