Abstract: (161 Views)
The accumulation heavy metals in the soil poses a significant risk to the health of plants, animals, and human communities. This study investigated the effect of small amounts of iron, zinc, and copper salts on hemocyte abundance, nutritional indices, and biological characteristics of the Ephestia kuehniella Zeller in-vitro. Fourth instar larvae were treated with iron, zinc, and copper salts at 25, 50, and 100 mg/kg in 24 and 48 h intervals. Immunological assessments included total hemocyte count, plasmatocytes, granulocytes, and phenol oxidase enzyme activity. The results demonstrated significant changes in immunological parameters compared to the control group. Notably, iron and zinc at 100 mg/kg exhibited the significant increase in enzyme activity at both 24 and 48 h. Conversely, iron caused a significant decrease in the activity of this enzyme after 24 h at 50 mg/kg when compared to other treatments. In terms of nutritional indicators, copper metal salt at 25 mg/kg enhanced the relative growth rate compared to the control. This preliminary study highlights the significant impact of zinc, copper, and iron salts on the biological characteristics and immune response of E. kuehniella. These findings suggest that the incorporation of small amounts of these metals into the insect's diet can induce biological and physiological disorders.
