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 5
Ultrastructure of fat body from young pharate adults of S. bullata following envenomation by N. vitripennis. At 0 h, numerous lipid droplets (LD) of varying sizes and densities were evident throughout the cytoplasm. Large, prominent nuclei (Nu) were also typical of fat body cells. By 24 h posttreatment, fat body cells from controls and envenomated hosts appeared nearly identical: numerous lipid droplets were present, yet few inclusions appeared in the cytoplasm of either cell type.
