Figure 10. Transmission electron micrographs comparing energy and waste reserves in nonparasitized and Thripinema fuscum-parasitized Frankliniella fusca females including electrondense vesicles within the (A) fat body underlying the host cuticle and (B) midgut cells of a parasitized F. fusca; (C) an obvious depletion of glycogen (arrow) in the fat body and (D) a juvenile nematode with an accumulation of glycogen and lipid deposits probably sequestered from the host; (E) cross-section of healthy F. fusca muscle tissue and (F) of muscle tissue from a female parasitized by T. fuscum with the presence of numerous glycogen granules (arrowheads); (G) glycogen granules embedded between the muscle fibres and mitochondria in a parasitized female; (H) uric acid crystals formed from nitrogenous waste within the cytoplasm of a Malpighian tubule of a healthy female; (I) the accumulation of secretory vesicles and uric acid crystals in the cytoplasm of the Malpighian tubule of a parasitized host. Abbreviations: gly, glycogen; lp, lipid; mf, muscle fibres; mt, mitochondria; sv, secretory vesicle; tr, trachea; ua, uric acid crystals; ves, electron-dense vesicles. Scale bars: A, B, E, F, 2 µm; D, G, H 1 µm; C, I, 5 µm.
