The hemocytes of insects are one of key components of immune system of insects against various stresses such as temperature changes. in hemolymph of Scrobipalpa ocellatella, Five types of identified hemocytes were prohemocytes (PRs), plasmatocytes (PLs), granulocytes (GRs), oenocytoids (OEs) and spherulocytes (SPs). The effect of different thermal stresses was also investigated for 24 hours on cellular defense of fifth instar larvae. At 28 and 30 °C, total hemocyte count (THC), GRS and OES of larvae was increased significantly compared to the control (20±1 °C). Also, chill stress (4 °C) showed a significant decrease in THC, PLs and GRS compared to the control. These findings could be used as a base for further investigation on the immunology studies of beet moth.
