Abstract:
In Othreis materna, vitellogenesis commences just after emergence of the moth and terminates in the seven day old moth. During vitellogenesis the developing oocytes showed marked changes in their shape, size and cytological organization. Developmental of terminal oocytes has been divided into five stages: the pre-vitellogenic, the early vitellogenic, the vitellogenic, the late vitellogenic and maturation stage. Day wise histological and cytological changes in the nurse cells, follicular epithelial cells and the size of terminal oocyte follicle have been studied. The average length and width of terminal oocyte follicles of last day pupa to seventh day old adult female were ranged from 142.10 ± 2.3 to 621.20 ± 6.9 μm and 110.60 ± 0.82 to 633.00 ± 2.9 μm, respectively. Wight of the ovary during the process of vitellogenesis was found to be 91.00 ± 2.0mg in last day of pupa to 374.00 ± 11.7 mg in seventh day old female moth.
