Contribution of the golgi Complex—Endoplasmic reticulum system during spermiogenesis in three species of phytophagous bugs (Hemiptera : Pentatomidae)

The participation of the Golgi complex—endoplasmic reticulum system during spermiogenesis in 3 species of phytophagous bugs (Acrosternum aseadum, Euchistus heros and Nezara viridula) were analysed at the ultrastructural level, after postfixation with osmium tetroxide\potassium iodide. Intense staining was found in the nuclear envelope, endoplasmic reticulum cisternae, Golgi complex, and in a meshwork of tubules scattered throughout the cytoplasm. It is shown that these compartments present a reducing environment. The presence of this kind of staining on the spermatid suggests an important participation of these structures on the differentiation process of this cell.
