Morphology and Ultrastructure of Brain Tissue and Fat Body from the Flesh Fly, Sarcophaga bullata Parker (Diptera: Sarcophagidae), Envenomated by the Ectoparasitic Wasp Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae)

Figure 2

Venom-induced changes in neuronal ultrastructure in brain tissue from young pharate adults of S. bullata envenomated by N. vitripennis. Following venom injection, some host brain cells (a) displayed prominent multilamellar bodies (Ml) by 6 hr postenvenomation. The mitochondria (M) in the 6 hr (b) and 24 hr (d) cells displayed similar structure with no evidence of swelling of the intermembrane space. By 24 h postenvenomation, some cells (c) contained multivesicular bodies (Mvb) and very swollen rough endoplasmic reticulum (rER), while others (adjacent cells in (c)) appeared to contain healthy rER.
