[Development of ovarioles and nurse cells cytoskeleton in Calliphora erythrocephala Mg. (Diptera; Calliphoridae)]
Abstract:
We have carried out the analysis of ovariole development and morphology in Calliphora erythrocephala Mg. (Diptera: Calliphoridae). It has been shown that several regions can be distinguished in C. erythrocephala germarium. In these regions cyst morphogenesis goes on stage by stage right up to the separation of formed egg chamber. There are fusomes of different degree of branching in germarium. Two egg chambers develop in C. erythrocephala vitellarium. We have researched distribution of actin filaments and ring canals formation in the nurse cells of C. erythrocephala. Diameter of ring canals increases from 1.5 microm in germarium zone to 14.7 microm at 3 and 4 stadies oogenesis. We suggest the scheme that illustrates irregular stretching of actin rollers which are formed during middle and late oogenesis around the ring canals joining proximal, sharply increased in size nurse cells with neighboring nurse cells.
