“…These abnormal changes require organisms' adaptation and mitigation. These responses can be vital as they can allow the studying of specific defense mechanisms against various and different stress factors [2,5,7,8,14].…”

“…The effects of various chemical or environmental pollutants on the insects' physiology and biochemistry have been investigated in various studies [1][2][3][4][5][6][7][8][9]. Environmental pollution sources including waste accumulation, industrial and agricultural activities have a direct effect on the amounts of cupper elevation than normal levels.…”

“…Therefore, improper organic waste management may cause a deleterious effect on the ecosystem components [22] and act as a source of many diseases [23] as a result of emissions of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs), greenhouse gases (CH 4 , CO 2 and N 2 O). The toxic emissions waste can lead to air pollution, global warming effect and exacerbated consequences associated with oxidative stress including changes in the macromolecules amount, elevation the levels of protein carbonyls (PC), lipid peroxides (LP) or DNA strand breaks [2,5,8,14,[23][24][25][26]. Besides that, many previous studies showed an increase in the heavy metals, especially Cu, Cr, and Cd, concentrations in the organic manure and waste [27,28].…”

“…The nonenzymatic includes β-carotene, α-tocopherol [14], and 2,2 diphenyl-1picrylhydrazyl (DPPH) [31], can neutralize free radicals, as hydrogen peroxide (H 2 O 2 ), and counteract the harmful effects of oxidative stress [29](. In addition to, SOD, catalase (CAT), glutathione-S-transferases (GSTs), glutathione peroxidase (GPx), β-esterase and ascorbate peroxidase (APOX) are antioxidant and detoxification enzymes that act as a critical defense line against ROS [8,[32][33][34]. So, the measurement of the oxidants, antioxidants, and damaged products levels can be done to quantify the oxidative stress [5,8,14].…”

Environmental pollution sources including waste or metal accumulation, industrial and agricultural activities can be dangerous. Also, contaminated organic waste (COW) with metals especially, copper ions (Cu 2+ ), can cause toxicity to various ecosystem components, enhance the production of reactive oxygen species (ROS) and consequently cause oxidative stress. The biochemical effect of the COW was monitored by assessing the oxidative stress parameters (OSP) using hydrogen peroxides (H 2 O 2 ), protein carbonyls (PC), lipid peroxides (LP), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), 2,2 diphenyl-1-picrylhydrazyl (DPPH), total antioxidant ability (TAA); β-esterase (β-EST); and total amount of protein (TAP) levels on the organic waste (kitchen and vegetable wastes); Hermetia illucens larvae; and larval excreta collected from 7-day post-treated kitchen and vegetables wastes with (1:10; g:mL) distilled water (DW) or 100 mg/mL Cu 2+ . The OSP levels were significantly higher in the experimental samples from Cu 2+ groups than in the control one. Besides that, the OSP levels of H. illucens larvae feed on vegetable waste was significantly higher than those feed on kitchen waste except for β-EST, PC, and TPA. The best, cheap and easy parameters of antioxidants to ensure the entomoremediation ability are total antioxidant capacity. Possible impacts of accumulated and Cu 2+ contaminated organic waste on H. illucens larvae were discussed. Also, the ability of insects to produce more antioxidants than input or output sources was approved. The potential use of the OSP as a bioindicator method of the bioremediation ability of H. illucens was proposed.
