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 4

Light micrographs showing toluidine blue stained fat body tissue from young pharate adults of S. bullata following envenomation by N. vitripennis. Fat body examined in control and envenomated flies displayed similar cytology at 0 and 24 h posttreatment: fat body cells were large with prominent nuclei (Nu) and numerous lipid droplets (LDs) evident throughout the cytoplasm. Magnification is 720x.
