1941Yeager & Munson in Jrnl. Agric. Res. LXIII. 263 In smears from the later instars, however, especially the fifth and sixth, and from the prepupal and early pupal stages, the blood-cell types, here called plasmatocytes and cystocytes, have been definitely identified among the glycogen-containing cells. 1959W. Andrew Textbk. Compar. Histol. ix. 366 (caption) Types of hemocytes from a butterfly larva, Laphrygma fragipida. The large cells are rhegmatocytes..the medium-sized ovoid to spindle-shaped cells, plasmatocytes. 1969R. F. Chapman Insects xxxiii. 676 Plasmatocytes are frequently the most abundant cell type. 1974Zeitschr. f. Zellforsch. CXLVII. 543 In fresh haemolymph preparations plasmatocytes are round, oval, or spindle shaped cells, 10-15 µm in diameter, with a central nucleus occupying approximately 40{pcnt} of the cell volume. 1987Jrnl. Insect Physiol. XXXIII. 147/2 Plasmatocytes were the only haemocyte type to exhibit locomotory activity over the substratum. |
