[The organization of the female reproductive system in the parasitic mite Myobia murismusculi (Trombidiformes: Myobiidae)].
The general morphology of the internal genital organs in Myobia murismusculi females have been studied by means of light and electron microscopy. It is shown, that their reproductive system is composed of the single ovary, long complex oviduct, cuticular vagina and receptaculum seminis. The apical region of the ovary is formed by the numerous processes of gonadian somatic cells. These cells generate the ovarian sheath and probably take place in oocyte's metabolism. Any nutritive cells in the Myobia ovary are absent. The vitellogenetic oocytes develop in the ovarian pouches like in other trombidiform mites. The oviduct consists of three parts, each of them has a specific ultrastructure and type of secretory product. Two proximal parts of the oviduct produce the egg-shell components, while the third distal part never contains oocytes. It could be suggested that this part produces a special secret onto the oocyte surface to glue the oocytes to the hairs of host.
