St. Petersburg;
The haemolymph of larvae and imago stages of Decticus verrucirus was studied with electron and light microscope.
PAS-positive and PAS-negative granules were detected in haemocytes. On the electronograms, granulocytes were
recognized as the only type of haemocytes. In the cytoplasm of granulocytes, granules of two types were found:
those of mitochondrial origin, and originating from the Golgi apparatus, respectively. The discharge of a secret
is realized by the merocrine way. Four stages of granulocyte development have been distinguished: 1) granule
formation and organelle development, 2) granule formation and accumulation, 3) active secretion, and 4) cell
destruction.
