The anatomy and histology of female reproductive organs of Gonocephalum brachyelytra (kaszab) (coleoptera: tenebrionidae)

In Gonocephalum brachyelytra (Kaszab), a pair of about 3.64 mm long and white ovary is found. Each ovary is composed of 28 to 38 numbers of ovarioles. The ovarioles are clearly differentiated into terminal filament, germarium and vitellarium. The germarium possesses 4 to 5 developing oocytes and trpohocytes which provide nourishment to the developing oocytes. The vitellarium possesses developing oocyte, maturing oocyte and large yolky globules i.e. resorptive oocyte. Each ovariole shows release of oogonial cells after maturation. The yolky materials of oocyte are well developed. The troophocytes shows intercellular spaces. These intercellular spaces provide pathway for protein to enter into the cytoplasmic area, and into the nuclear region. It shows protein deposition and increase the process of mitosis and meosis. As a result active oviposition is observed.
