Cadmium (Cd) is a toxic heavy metal associated with osteoporosis, liver, and kidney disease. The black solder fly (BSF) Hermetia illucens may be exposed to Cd during the transformation of livestock manure. BSF has high tolerance Cd. In previous work laboratory, we found that vitamin E (VE) play role in exposure. main findings are as follows: larvae pretreated exogenous VE had heavier body weight, lower content toxicity under similar Even exposure at concentrations 300 700 mg/kg concentration 100 still reduced 85.33 % 84.43 %, respectively. best-fitting models showed metallothionein (MT) content, oxidative damage (8-hydroxydeoxyguanosine malondialdehyde content), antioxidant power (total power, peroxidase activity) great influence on bioaccumulated larvae. degree was pretreatments. This variation can explained by their changed MT increased because VE. These results reveal roles insects defense against provide new option for prevention therapy caused
