“…Additionally, during the investigation of the combined effects of heavy elements (cobalt, zinc, tannic acid, and gallic acid) and phenolic compounds (gallic acid, tannic acid) on the larvae of Hyphantria cunea , in Drury, it was noted that the pupae of larvae fed diets enriched with Fe had significantly less lipid content than the larvae in the control group [ 41 ]. In a seminal study conducted by Chatterjeet et al [ 42 ], the entomocidal properties of chemical compounds containing Co 3+ and Fe 3+ were investigated, specifically focusing on their ovicidal and sterilizing effects. These investigations align with our observations pertaining to the deleterious impacts of nano-iron on the life table and life cycle of aphids.…”

The use of nanofertilizers has both advantages and concerns. One benefit is that nano-fertilizers can enhance plant resistance against insect pests, making them a valuable strategy in integrated pest management (IPM). This study focused on the effect of wheat leaves treated with nano-chelated fertilizers and nitrogen (N) fertilizer on the wheat aphid (Schizaphis graminum Rondani), a harmful pest of wheat plants that transmits dangerous viruses. The nano-Cu treatment showed the longest pre-adult longevity. Additionally, the nano-Cu treatment resulted in the lowest adult longevity, fecundity, nymphoposition day number, intrinsic rate of population growth (r), finite rate of population increase (λ), and net reproductive rate (R0) and gross reproductive rate (GRR). Also, nano-Cu treatment led to the highest amount of (T). The N treatment led to the highest levels of fecundity, nymphoposition days, r, λ, and R0. Nano-Fe and nano-Zn demonstrated fewer negative effects on S. graminum life table parameters than nano-Cu. Our results indicate that N treatment yielded numerous advantageous effects on the wheat aphid while simultaneously impeding the efficacy of the aphid control program. Conversely, nano-Cu treatment exhibited a detrimental influence on various parameters of the aphid’s life table, resulting in a reduction in the pest’s fitness. Consequently, the integration of nano-Cu should be seriously considered as a viable option in the IPM of the wheat aphid.
