An Ultrastructural and Fluorescent Study of the Teratocytes of Microctonus aethiopoides Loan (Hymenoptera: Braconidae) from the Hemocoel of Host Alfalfa Weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae)
Figure 3
Semithin sections of teratocytes were dual-stained with Dil for plasma membrane and with TO-Pro3 for nucleus. (a) Transmitted light micrograph of teratocyte showing internal structure of the cell. (b) Same cell section stained with Dil showing strong staining of plasma membrane and an unidentified internal membranous network. (c) Same section stained with TO-Pro3 showing intense staining of chromosomal DNA within the large amorphous nucleus. (d) Overlaid images from (a) to (c) showing red plasma membrane and blue amorphous nucleus. N: nucleus, PM: plasma membrane, UIM: unidentified internal plasma membrane network. Scale bars = 20 μm.
