Vitellogenesis in two caryophyllidean cestodes Caryophyllaeus laticeps and Khawia sinensis, parasitizing cyprinid fishes, were examined using light(LM)and transmission electron microscopy(TEM)and cytochemical staining for glycogen. Mature vitelline folicles consist of vitelline cells at various stages of development and an interstitial tissue. Maturing and mature vitellocytes contain vitelline material in the form of single small shell globules, which fuse and give rise to the large shell globule clusters.Glycogen was present in the cytoplasm and in the nucleus of the mature vitellocytes. Small lipid droplets were found in the cytoplasm of C. laticeps. "Lamellar granules" were observed in the cytoplasm of the mature vitellocytes in K. sinensis.
