The haemolymph of Tettigonia cantons (Fuess) has been studied at the preimago and imago stages with both electron and light microscopic
methods. PAS-negative granules were detected in histochemical reactions. On electronograms, one type of haemocytes was referred to as granulocytes
recognized in haemolymph. In the cytoplasm of granulocytes, two types of granules were found: those of mitochondrial origin, and those being derivatives
of the Golgi apparatus. Secret discharge is realized by the merocrine way. Four stages of granulocyte development are distinguished: the formation of
granules and organelle development; the formation and accumulation of granules, active secretion, and cell destruction.
Key words: Tettigonia cantons, haemocytes, granulocytes, haemolymph, Golgi apparatus
