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 6
Ultrathin sections of teratocytes were stained with uranyl acetate and Lead citrate. (a) Dense microvilli, rough endoplasmic reticulum, and mitochondria associated with plasma membrane. Scale bar = 500 nm. (b) TEM image of unidentified membranous network located at opposite sides of the teratocyte. Scale bar = 1 μm. (c) TEM image of one arm of amorphous nucleus showing intense staining of heterochromatin, numerous lipid droplets, and pigment. Scale bar = 1 μ. (d) Same cell showing microvilli, rough ER, and associated mitochondria. Scale bar = 500 nm. (e) Same cell with higher magnification showing mitochondria and lipid droplets. Scale bar = 100 nm. (f) Electron micrograph of the internal structure of the same area of the teratocyte showing starch and pigment granules and lipid droplets. Scale bar = 500 nm. PM: plasma membrane; MV: microvilli; UIM: unidentified membranous network; N: nucleus; L: lipid droplets; RER: rough endoplasmic reticulum; M: mitochondria; S: starch; P: pigment granules. Scale bar = 20 μm.
