The present study aims to evaluate the different nanoparticles (Cu NPs, KI Ag Bd and Gv NPs) against 4th instar Spodoptera frugiperda larvae as well microbial toxicity, phytotoxicity, soil pH. Nanoparticles were tested at three concentrations (1000, 10000, 100000 ppm) using two methods (food dip dip) S. larvae. Results (from larval method) showed that among nanoparticles, NPs caused 63%, 98%, 98% mortality within 5 days in treatment of 1000, ppm, respectively. After 24 h post treatment, a 1000 ppm concentration 95%, 54%, 94% germination rates Metarhizium anisopliae, Beauveria bassiana, Trichoderma harzianum, phytotoxicity evaluation clearly did not affect morphology corn plants after treatment. nutrient analysis results no effect was observed pH or nutrients compared control treatments. are toxic

Biogenic synthesis of titanium nanoparticles by Streptomyces rubrolavendulae for sustainable management of Icerya aegyptiaca (Douglas)

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 9, 2025

Abstract Biosynthesized nanoparticles have a variety of applications, and microorganisms are considered one the most ideal sources for synthesis green nanoparticles. Icerya aegyptiaca (Douglas) is pest that has many generations per year can affect 123 plant species from 49 families by absorbing sap bark, forming honeydew, causing sooty mold, attracting invasive ant species, leading to significant agricultural losses. The purpose this work was synthesize titanium dioxide (TiO 2 -NPs) marine actinobacteria evaluate their insecticidal effects on (Hemiptera: Monophlebidae), in addition explaining protein electrophoresis analysis SDS‒PAGE proteins control treated insects after 24, 72 120 h exposure. In all, seven actinobacterial isolates, potent which potential produce hydroxide-based -NP2), DNA sequences 99.9% like those Streptomyces rubrolavendulae (MCN2) according nucleotide alignment phylogenetic tree. produced TiO -NPs were verified UV examination characterized FT-IR, XRD, TEM, EDX, DLS analyses. Toxicological results revealed high mortality rates reaching 55, 62.5, 80 95% at TiO2-NPs dose 120,250,500 1000 ppm respectively. Compared with control, TiO2-NP spraying caused changes pattern I. aegyptiaca, as indicated disappearance normal bands appearance other bands, well quantitative qualitative content application MNC2 offers new alternative strategy modern approach nanotechnology.

The pulse beetle Callosobruchus maculatus is a serious insect pest of stored legumes. Therefore, the management such pests has become necessity as it causes great economic loss to its plant host. Unfortunately, programs against C. encounter several obstacles, generation insecticide resistance and environmental hazards traditional insecticides. current study was designed overcome these obstacles by using synthetic nanoparticles alternative In this study, form eggshell-based hydroxyapatite (HAPNPs) used control agent maculatus. This material selected because safety, which ensured due wide spectrum applications in our daily activities. HAPNPs originating from eggshells were characterized XRD, FTIR, TEM. obtained results revealed lack impurities synthesized particles that average plate size ∼62.8 nm, while rod structure length width ∼91 nm ∼22.7 respectively. A comparative on toxicity Malathion showed significant impact NPs than positive insecticide. Based finding, further analyses performed understand subsequent effects.

This study comprehensively assessed the insecticidal activity ZnO-NPs against bean weevil, Acanthoscelides obtectus Say. (Coleoptera: Chrysomelidae), by analyzing mortality rates dose-dependent manner under controlled laboratory conditions. were synthesized characterized using Scanning Electron Microscopy (SEM), confirming spherical shape nanoscale dimensions (~100 nm). Mortality was monitored over 10-day period at doses 100, 250, 500, 750 1000 mg kg⁻¹. Abbott formula used account for natural mortality. two-way ANOVA results revealed that both dose exposure duration had significant effects on insect rates. Also, One-Way showed increase mortality, with highest (1000 kg⁻¹) achieving corrected rate 93.3%. These findings highlight potential sustainable alternative conventional chemical insecticides, particularly integrated management strategies stored products. Future studies should focus optimizing control practices storage facilities evaluating long-term non-target organisms.
