چکیده انگلیسی
The venom apparatus of the endoparasitic wasp Pteromalus puparum (Hymenoptera: Pteromalidae) was studied with light and electron microscope and was subjected to the electrophoretic and immunohistochemical analyses. Typically its venom apparatus consists of an unbranched venom gland and a venom reservoir, which is associated with a Dufour gland. The venom gland is lined by a series of secretory units. Each secretory unit comprises a secretory cell and a duct cell. The secretory cell is associated with an end apparatus to collect its secretions into the gland lumen. Secretory cells in the venom gland are characterized by extensive rough endoplasmic reticulum and numerous electron-dense vesicles in the distal and middle parts. They also exhibit several secretory granules and vacuoles. The venom reservoir presents three distinct regions: an external layer, composed by numerous fine muscle fibers; an internal layer, represented by epithelial cell with large nucleus; and an intima portion, represented by thin and uniform organization. The morphological aspect of numerous well-developed organelles responsible for protein generation observed is in agreement with the electrophoretic and immunohistochemical results which reveal that the rich proteinaceous components are present in the venom gland and venom reservoir. The venom proteins are first mainly produced in the secretory unit of venom gland, then drained to the lumen through the end apparatus, and are finally collected and stored in the venom reservoir.
