Fig. 2

Air dried and May Grünwald Giemsa-stained cytological slides from honeybee haemolymph. A) some hemocytes (arrows), a group of plasmatocytes (arrowhead), and a group of granulocytes (open arrow) are present; scale bar = 200 μm. B) some hemocytes (open arrow), a granulocyte with some dark colored granules of PO (arrow), and a plasmatocyte phagocytizing a foreign particle (arrowhead); scale bar = 100 μm. C) a group of “activated” plasmatocytes (arrowhead), and a single, inactive plasmatocyte (arrow); scale bar = 50 μm. D) a group of activate and “phoamy” plasmatocytes during phagocytosis; scale bar = 50 μm. E) some small hemocytes (arrowhead), and a group of plasmatocytes (arrows) at different stages of activation; scale bar = 100 μm. F) Small hemocytes (open arrow), a big and pigmented oenocytoid (arrow) with a group of phagocytizing plasmatocytes (arrowhead); scale bar = 50 μm
