By A. P. Gupta

The functionality of insect blood cells has lengthy questioned scientists. This much-needed quantity, first released in 1979, makes an attempt to give an explanation for the kinds and capabilities of insect hemocytes, making a good foundation from which paintings within the box could continue. Insect Hemocytes had its origins in a symposium held on the XV overseas Congress of Entomology (1976). it's a coherent presentation whose members have been probably the most eminent experts within the box.

Migratoria and larvae of M. melolontha were found to have hemopoietic tissues with strong similarities; C. erythrocephala, although rather similar to other species, shows interesting pecularities in its hemopoiesis. These data will now be given in some detail. Fig. 13. Hemopoietic organ of Gryllus after severe bleeding (2 days). Compare with Fig. 2. Semithin section, fuchsin stain, x 140.

Mesothelial cell layer surrounds organ (upper left); certain cells are very digitated and in close contact with collagenlike fibers (capsule). Cortex has regular organization, regular cells (dotted) and fibers forming a dense network; isogenic islets of differentiating hemocytes are seen in this network; note numerous cell divisions. Medulla or lumen (lower part of figure) shows accumulation of differentiated hemocytes of different cell types present in hemolymph; medulla of organ is in communication with dorsal vessel.
