Organization of the tropharia in the telotrophic ovaries of the dipsocoromorphan bugs Cryptostemma alienum Herrich-Schaeffer and C. carpaticum Josifov (Heteroptera : Dipsocoridae)
The tropharia of the dipsocoromorphan bugs, Cryptostemma alienum and Cryptostemma carpaticum (Heteroptera : Dipsocoridae) are composed of 30–50 mononucleate nurse cells that are connected with centrally located trophic cores by means of broad cytoplasmic strands. The anteriormost nurse cells are mar...

| description | The tropharia of the dipsocoromorphan bugs,
Cryptostemma alienum and
Cryptostemma carpaticum (Heteroptera : Dipsocoridae) are composed of 30–50 mononucleate nurse cells that are connected with centrally located trophic cores by means of broad cytoplasmic strands. The anteriormost nurse cells are markedly smaller and often reveal signs of degeneration. The trophic core is surrounded and penetrated by elaborate F-actin meshwork. Arrested oocytes and prefollicular cells are localized at the base of the tropharium. Anagenesis of heteropteran ovarioles is discussed in relation to the findings presented. |
