“…This practice has been linked to detrimental effects on the ozone layer, worker health, pest resistance, and environmental pollution. These issues have been extensively documented in the literature (Deraz et al, 2022;Aidbhavi et al, 2023). In response to the negative consequences resulting from the widespread of insects in storage, extensive use of chemical pesticides has been implemented without consideration for environmental relationships and their impact on the ecosystem, and ecological balance has been disrupted.…”

The objective of this investigation was to assess the insecticidal efficacy of essential oils derived from eucalyptus (Eucalyptus camaldulensis) and spearmint (Mentha spicata) against two species of stored-product insects. The process of Clevenger-type water distillation was employed to extract essential oils from two distinct plant species. Subsequently, the insecticidal properties of these oils were evaluated against specimens of the American wheat weevil (Rhyzopertha dominica) and the red flour beetle (Tribolium castaneum), belonging to the Coleoptera: Bostrichidae and Tenebrionidae families, respectively. Eucalyptus oil exhibited the highest level of inhibition of insects’ reproduction. Still, when tested on adults of both types of insects, eucalyptus and spearmint oils were more effective than the control treatment. A complete inhibition of egg-laying activity (100%) was achieved using a 7% concentration of eucalyptus oil. The trials were done within controlled laboratory settings, with a notable absence of tests conducted under authentic operational conditions. Researchers who want to learn more about using essential oils as insecticides in the future should focus on making pesticide formulations that work well in a wide range of production settings.

Plant-based biological nanoparticles (NPs) synthesis is a new technique where biological molecules and their combinations in plant aqueous extract decrease metal salts, which have a dual role in the fabrication and stabilization of metallic NPs. Here, we used aqueous extract from the duckweed (Lemna minor) plant to biosynthesize silver NPs (AgNPs), which were verified by a shift in color from pale brown to dark brown. AgNPs were then further characterized.By High Performance Liquid Chromatography (HPLC) analysis, the most abundant compound in the aqueous extract were vanillic acid, benzoic acid, quercetin, resveratrol, ferulic acid, rutin, p-hydroxy benzoic acid, rosmarinic acid, ellagic acid, and o-coumaric acid. Scanning Electron Microscopy (SEM), micrograph revealed spherical-shaped synthesized AgNPs with an average size of 40.56 nm. Capping and stabilizing agents, present in the form of various biomolecules, were responsible for the prolonged stability of the produced AgNPs, as proven by FTIR analysis. The Zeta potential of the surface electric charges of AgNPs was determined to be − 27 mV. The UV–Vis spectrum indicates a broad surface plasmon resonance (SPR) absorption peak at 450 nm. The EDAX test confirmed the presence of silver in the suspension. Green-produced AgNPs had the highest insecticidal activity against Sitophilus oryzae, with LC50 values of 6.08 µg/mL compared to adults of Tribolium castaneum, which were 7.03 µg/mL. All the assays clearly showed that formulated AgNPs 1% DP showed that increasing exposure intervals and concentrations resulted in a gradual increase in the mortality of adult T. castaneum and S. oryzae exposed to treated wheat seeds. The effect of post-toxic levels of AgNPs on the progeny counts of adults of T. castaneum and S. oryzae showed that increasing exposure intervals and concentrations resulted in a gradual increase in the mortality of adult T. castaneum and S. oryzae exposed to treated wheat grains. The effect of post-toxic levels of AgNPs on the progeny counts of adults of T. castaneum and S. oryzae and resulted that concentration of 0.2 g/100 g seed being the most effective one, with higher reductions in F1-progenythan than other concentrations and malathion (1% DP) during storage for 1 year, as well as a significant positive effect on seed germination during storage. The present work suggests that eco-friendly biosynthesized and formulated AgNPs are promising green insecticides that can be used as an alternative method to control and protect seeds against adults of T. castaneum and S. oryzae to overcome the synthetic insecticide problems.
