The present studies showed that two cell populations were found in haemocytes: large cell with high granularity and small cell with low granularity by flow cytometry FCM on light scanttering pattern. Two distinct cell types were identified based on phase contrast microscope: one type of cell was dark and dioptric aberration, while the other was bright and dioptric strong. By Giemsa and H.E staining, cytoplasmic staining were heterogeneous and internal particles were obvious in one type of cell, while cytoplastic staining were homogeneous and internal particles were inexistent in the other type of cell. By transmission electron microscope, we found that the mitochondria, Golgi apparatus organelles were rich and internal particles were obvious in one type of cells, and contrary to the another cells.
