“…High Cu 2+ concentrations (16 and 32 mg/kg) significantly lengthened the developmental time of S. litura larvae compared with low Cu 2+ concentrations. Similar results were also found for Boettcherisca peregrine ( Wu et al 2007 ) and Aedes aegypti ( Miranda et al 2022 ). Shu et al (2012) reported that the larval stage of S. litura was significantly prolonged with an increase in Pb concentration.…”

“…Our findings are similar to those of Shu et al (2015) , who found that high Pb concentration (200 mg/kg) significantly reduced the survival rate of S. litura larvae. While the binding of Cu 2+ to metallothionein has a detoxifying effect ( Andreani et al 2020 ), excess Cu 2+ still damages the structure of the insect midgut ( Miranda et al 2022 ). Similar results have been observed for other heavy metals such as Cadmium (Cd) ( Baghban et al 2014 ), Zn ( Ali et al 2019 ), and Pb ( Shu et al 2015 ).…”

Copper (Cu2+) is a micronutrient that promotes the development and reproduction of organisms. However, with the rapid expansion of modern industry and agriculture, Cu2+ concentrations are increasing, which might have negative impacts on biological and ecological safety. Spodoptera litura is not only an intermittent outbreak pest but also can be used as a model organism to assess environmental and ecological risks. Therefore, the effects of the life history and population parameters of S. litura fed on artificial diets with different Cu2+ concentrations were analyzed using the age-stage, two-sex life table. Our results showed that not only the preadult survival rate but also the intrinsic rate of increase (r) and the finite rate of increase (λ) were significantly increased under exposure to low Cu2+ concentrations (2, 4, and 8 mg/kg). In addition, the population growth of S. litura was significantly faster, indicating that S. litura can adapt well to low concentrations and is likely to undergo outbreaks of damage. Whereas, in addition to a significant reduction in preadult survival rate, population growth rate, pupal weight, pupal length, adult body weight, and oviposition were also significantly reduced under exposure to high Cu2+ concentration (32 mg/kg). And when the concentration reached 64 mg/kg, the survival rate of adults was extremely low, suggesting a decrease in the adaptation of S. litura. These results can help to understand the population dynamics of S. litura and predict potential ecological risks.

“…Because larvicidal assays results were obtained on the third larval stage, we started the exposure at this stage to analyze the larval development, in according to published works (Fernandes et al, 2019; Miranda et al, 2021; Silva et al, 2019). Interestingly, a significant ( p < 0.05) delay was observed in all extract‐treated groups, with a higher number of larvae and lower number of adults than in control (Figure 2a).…”

This study evaluated the effects of acute exposure of Aedes aegypti third instar (L3) larvae to the saline extract of Opuntia ficus‐indica cladodes on the biological cycle and fertility of the emerging adults. For this, larvae were treated for 24 h with the extract at ¼ LC50 (lethal concentration to kill 50% of larvae), ½ LC50 or LC50; the development and reproduction of the emerged adults were evaluated after a recovery period of 9 days. The resistance of proteins in the extract to hydrolysis by L3 digestive enzymes and histomorphological alterations in the larval midgut were also investigated. The extract contained lectin, flavonoids, cinnamic derivatives, terpenes, steroids, and reducing sugars. It showed a LC50 of 3.71% for 48 h. The data indicated mean survival times similar in control and extract treatments. It was observed development delay in extract‐treated groups, with a lower number of adults than in control. However, the females that emerged laid similar number of eggs in control and treatments. Histological evaluation revealed absence of bacterial and fungal microorganisms in the food content in midguts from larvae treated with cladode extract. Electrophoresis revealed that three polypeptides in the extract resisted to hydrolysis by L3 digestive proteases for 90 min. The lectin activity was not altered even after 24‐h incubation with the enzymes. In conclusion, the extract from O. ficus‐indica can delay the development of Ae. aegypti larvae, which may be linked to induction of an axenic environment at larval midgut and permanence of lectin activity even after proteolysis.

“…On the other hand, mortality rises and population development is negatively impacted when insects feed on sources with greater concentrations of Cu, as has been reported in Boettcherisca peregrina [ 52 ] and Apis mellifera L. [ 59 ]. Furthermore, it has been established that an elevated level of copper ions results in significant harm to the insect’s midgut [ 60 ]. The damaging impacts of the elevated copper concentration on the midgut’s microbial flora lead to a decline in the insect’s ability to survive and disrupt its development [ 61 ].…”

“…The Cu concentration utilized in this study is potentially detrimental since it resulted in the lowest intrinsic rate of population increase (r) and finite rate of population increase (λ), indicating a negative influence on these parameters. Numerous studies have indicated that high Cu concentrations prolong the larval development period of S. liuta , Aedes aegypti L., and B. peregrina , likely due to a drop in emergence- and appearance-related protein levels [ 52 , 60 , 64 ]. In the present study, the length of the pre-pubertal period was significantly higher in the nano-Cu treatment than in all other treatments.…”

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.
