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 3
Light micrographs showing apoptosis in brain tissue of S. bullata following envenomation by N. vitripennis. Detection of apoptotic (ApN) or nonapoptotic neurons (N) relied on in situ labeling based on the TUNEL assay. Apoptotic cells are evident as darkly stained cells (peroxidase) in each panel. Several swollen neurons (SNs) were evident by 24 postenvenomation. Brain tissue extracted from nonparasitized flies served as controls. Magnification is 750x.
