Zinc oxide nanoparticles (ZnO NPs) are now commonly used in many consumer products (detergents, antibacterial products, protective creams). The aim of the study is to determine the ecotoxicological effects of ZnO NPs on the survival and in the total hemocyte counts of Galleria mellonella L. 1758 (Lepidoptera: Pyralidae) with two different methods (automated cell counter and hemocytometer). A toxicity test was performed to determine the lethal concentrations of ZnO NPs on larvae by force feeding method. After 24 h the treatment, LC50 was 6.03 mu g/10 mu l and LC99 was 12.86 mu g/10 mu l for force fed larvae according to probit assay. The NP that induced changes in the total hemocytes counts were counted by optical microscopy (larvae exposed to four different doses of ZnO NPs) and by automated cell counter. Analyses of total hemocyte counts of the insect were performed with four doses (0.5, 1, 2.5, 5 mu g/10 mu l)
