“…The finding of this study came along with a previous study that used different concentrations of methanol leaf extract, green synthesized silver (AgNPs), and chitosan nanoparticles (CsNPs) using A. vera and Nerium oleander against Musca domestica and indicated that the nanoparticles were more potent than the methanol extract 97 . Furthermore, a corresponding study indicated that the larvicidal effect of silver nanoparticles AgNPs and CsNPs encapsulated A. vera gel extract against M. domestica was documented and their relative efficacies were almost 40.65 and 148.51 times more effective than the A. vera crude extrac 82 .…”

Hyalomma dromedarii is an important tick species infesting livestock. This work evaluated the novel adulticidal, insect growth-regulating, and enzymatic efficacy of ethanol plant extracts of Aloe vera and Rheum rhabarbarum and their nanoemulsions against males and engorged females of the camel tick, H. dromedarii. The physicochemical properties of nanoemulsions were evaluated. The High-Performance Liquid Chromatography (HPLC) analyses indicated that the extracts contained polyphenols and flavonoids, which could enhance their acaricidal effect. Dynamic light scattering (DLS) of the nanoemulsions of A. vera and R. rhabarbarum were 196.7 and 291 nm, whereas their zeta potentials were − 29.1 and − 53.1 mV, respectively. Transmission electron microscope (TEM) indicated that nanoemulsions showed a regular spherical shape (less than 100 nm). Fifteen days post-treatment (PT) with 25%, the mortality% of A. vera and R. rhabarbarum were 88.5 and 96.2%, respectively. Five days PT, the median lethal concentration values of A. vera, R. rhabarbarum, and their nanoemulsions were 7.8, 7.1, 2.8, and 1.02%, respectively, and their toxicity indices were 91.02, 100, 36.4, and 100%, respectively. Their median lethal time values PT with 3.5% were 6.09, 5.09, 1.75, and 1.34 days, respectively. Nanoemulsions enhanced the efficacy of the crude extract 1–7 folds, 5 days PT, and accelerated their speed of killing ticks 2–4 times. The total protein and carbohydrates, Acetylcholinesterase, Alpha esterase, and Amylase were affected PT. The reproductive potential of engorged females was adversely impacted. In conclusion, the novel A. vera and R. rhabarbarum extracts were promising acaricides, and their nanoformulations enhanced their efficacies.

“…En relación con lo anterior un estudio realizado por Amjad et al, (2022) menciona que al aumentar la dosis de Ag-NPs aplicadas a Sitobion avanae la actividad enzimática de la glutatión-s-tranferasa y catalasa aumentó. Así mismo, se ha documentado una interacción entre las Ag-NPs y enzimas como catalasas, superóxido dismutasa y glutatión-s-tranferasa en larvas de Musca domestica (Ramadan et al, 2020).…”

Background: The synthesis of nanoparticles from living organisms better known as biological synthesis or green synthesis has become a potential tool due to the advantages it provides compared to other existing synthesis methods. Green synthesis is presented as an environmentally friendly, safe, less toxic and cost-effective alternative. Due to these properties green nanoparticles have been implemented in the field of agriculture, mainly as nanopesticides. Objective: To review the reports on the evaluation of green nanoparticles against insects, as well as the knowledge on the possible modes of action of these nanoparticles. Methodology: A compilation of scientific information was made in different search engines, from which those that evaluated nanoparticles by green synthesis as insecticides were selected. Results: Among the modes of action caused by metallic nanoparticles, the following stand out: damage and histological changes at intestinal level, antifeedant activity, physical damage to the cuticle, decreased cell viability and inhibition of fecundity. Implications: the availability of information on nanoparticles is fundamental to be able to scientifically propose their implementation in insect pest management strategies. Conclusion: green synthesis of nanoparticles is presented as an alternative to produce nanoinsecticides; however, further research is needed on the mechanisms of action on insects, as well as their long-term repercussions on human and environmental health.

“…The bark extract of N. oleander has been found to contain a variety of plant secondary metabolites, including steroids, terpenoids, flavonoids, cardenolides, cardiac glycosides, and longchain esters. Massive biological effects have been noted, including cardiac tonic, diuretic, cytotoxic, antibacterial, anti-platelet aggregation, anti-inflammatory, hepatoprotective, anticancer, anti-hyperlipidemic, antiulcer, and anti-depressant action in the central nervous system [10]. Plant extracts are rich in phytochemicals, which operate as reducing and stabilizing agents and demonstrate antibacterial activity against some bacterial and fungal strains.…”

Natural polymers are often non-toxic, biodegradable, biocompatible, and safe. A novel ligand was synthesized as a natural polymer using chitosan and oleander plant extract [(2R,3S,4R,5S)-5-(acetoxyamino)-4-hydroxy-3,6-dimethoxytetrahydro-2H-pyran-2-yl) methyl (16R)-3-(((2S,4S,5R)-4-methoxy-2,5-dimethyltetrahydro-2H-pyran-2-yl)oxy-10,13,16-trimethyl-17-(5-oxo-2,5-dihydrofuran-3-yl) hexadecahydro-14H-cyclopenta [a] phenanthren-14-yl) phthalate] (Chitosan-Ph-Oleander). This ligand and its complexes with several metals (Cr+3, Mn+2, Fe+3, Ni+2, Cu+2, Zn+2) were characterized using FTIR, UV-visible and 1H-NMR spectroscopy, as well as by molar conductivity, magnetic moment, and TGA analysis. The biological activity for the prepared polymer and its complexes was studied to inhibit the effectiveness of some bacteria found in polluted water taken from hospitals wastewater. The effectiveness of inhibition was tested on Fusarium oxysporum fungus, which causes wilting, rotting and seedling death diseases in various types of plants. The elemental and spectral investigation results showed that all prepared compounds had octahedral geometry. Compared to the free ligand, all metal complexes showed discernible antibacterial activity. The zinc(II) complex, in comparison to other metal complexes, showed higher antibacterial activity against Faecal streptococci bacteria (G+) and Pseudomonas aeruginosa bacteria (G−). In addition, the inhibition rate of the effectiveness of the F. oxysporum fungus reached ~50%.
