Abstract： [Objectives] To describe the characteristics and morphology of the hemocytes of Bryodema nigroptera Zheng and describe the evolutionary relationships between the different types of hemocytes in order to further understanding of the cellular immunology of locusts and provide a basis for locust prevention and control. [Methods] Hemocytes of B. nigroptera were stained with Wright-Giemsa and observed under an optical microscope. [Results] B. nigroptera has 8 types of hemocytes; prohaemocytes, plasmatocytes, granulocytes, oenocytoids, cystocytes, adipohemocytes, vermiform cells and megakaryocytes. [Conclusion] In adults, prohaemocytes accounted for 1%, plasmatocytes for 32.2%, granulocytes for 57.3%, oenocytoids for 1%, Cystocytes for 6%, adipohemocytes for 1%, vermiform cells for 1% and megakaryocytes for 0.5%, of all hemocytes. Granulocytes were the most abundant followed by plasmatocytes, and megakaryocytes were the least abundant.
