Fungi are used to synthesize metal nanoparticles such as silver nanoparticles (AgNPs) because of their specifications as lower toxicity and eco-friendly behavior. Extracellular mycosynthesis of Lecanicillium lecanii silver nanoparticles (AgNPs) was performed, which was done by a redox reaction, where the filtrate crude of L. lecanii acts as a reducing and stabilizing agent for the formation of nanoparticles. The green synthesized AgNPs were evaluated as insecticidal against the adults of sunn pest Eurygaster testudinaria. The AgNPs were characterized by ultraviolet-visible (UV–vis) spectroscopy, Fourier transform infrared (FITR) spectroscopy, X-ray diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM). The UV–Vis spectroscopy showed a characteristic absorption peak at 418.5 nm due to surface plasma resonance. FESEM analysis showed that synthesized AgNPs were semi-spherical with an average size of 39.45 nm. The AgNPs showed strong activity in mortality of adults of E. testudinaria under conditions during different periods of time to recorded 100% at concentration 100 ppm compared with 0.00% in control treatment after 10 days from treatment.

“…Despite their potential benefits, EOs have constitutive drawbacks linked to their properties, such as phytotoxicity, low solubility in water, high volatility and fast degradation (Moretti et al 2002;Regnault-Roger et al 2012;Krzyżowski et al 2020). Nevertheless, recent advances in nanotechnology can remedy these inconveniences through a constant release of the active ingredients, a reduction in degradation, and by improving their solubility and stability patterns (Kah et al 2013;de Oliveira et al 2014;Campolo et al 2017Campolo et al , 2020aMaroofpour et al 2021;Cherif et al 2022).…”

Zoophytophagous hemipteran predators provide relevant biological control services and their applications are consolidated in greenhouse pest management. The use of plant essential oils (EOs) for sustainable crop protection is being currently promoted. However, further knowledge of the potential side effects of EOs on predatory mirids (Hemiptera: Miridae) is required. Here, we evaluated the non-target impact of four EOs (anise, fennel, garlic and lavender) on the generalist predator Nesidiocoris tenuis (Reuter) in the laboratory. The baseline toxicity of EOs was firstly assessed on N. tenuis adults following topical contact exposure. Then, the predator reproduction and orientation behavior was tested following the exposure to three estimated EO lethal concentrations (LC1, LC10 and LC30). Garlic EO had the lowest estimated LCs (e.g., LC30 1.34 mg mL−1), being thus the most toxic compound among the tested EOs. The estimated LC30s for lavender, anise and fennel EOs were 2.75, 4.55 and 5.17 mg mL−1, respectively. The fertility and the orientation behavior of N. tenuis females was negatively affected by all the EOs at the highest tested concentration. Nevertheless, anise EO at LC1 and LC10 caused no sublethal effects on N. tenuis. Our findings suggest that careful attention should be given when EOs are used in combination with N. tenuis in pest management programs.

“…Fortunately, recent studies have been working on nanotechnology to produce residue-free nano-formulations of insecticides with minimum environmental persistence and better insecticidal activity as well as the least negative effect to the environment and human health [ 22 , 23 ]. In addition, the application of nano-based insecticides can delay the development of resistance against the insecticides [ 24 ]. Recently, various nano-formulations with different nanoparticles have been developed, specifically, silica MgO, CuO, Ag, and ZnO nanoparticles with confirmed better insecticidal activity [ 25 ].…”

The diamond back moth, Plutella xylostella, causes severe damage at all crop stages, beside its rising resistance to all insecticides. The objective of this study was to look for a new control strategy such as application of insecticide-loaded carbon dot-embedded fluorescent mesoporous silica nanoparticles (FL-SiO2 NPs). Two different-sized methoxyfenozide-loaded nanoparticles (Me@FL-SiO2 NPs-70 nm, Me@FL-SiO2 NPs-150 nm) were prepared, with loading content 15% and 16%. Methoxyfenozide was released constantly from Me@FL-SiO2 NPs only at specific optimum pH 7.5. The release of methoxyfenozide from Me@FL-SiO2 NPs was not observed other than this optimum pH, and therefore, we checked and controlled a single release condition to look out for the different particle sizes of insecticide-loaded NPs. This pH-responsive release pattern can find potential application in sustainable plant protection. Moreover, the lethal concentration of the LC50 value was 24 mg/L for methoxyfenozide (TC), 14 mg/L for Me@FL-SiO2 NPs-70 nm, and 15 mg/L for Me@FL-SiO2 NPs-150 nm after 72 h exposure, respectively. After calculating the LC50, the results predicted that Me@FL-SiO2 NPs-70 nm and Me@FL-SiO2 NPs-150 nm exhibited better insecticidal activity against P. xylostella than methoxyfenozide under the same concentrations of active ingredient applied. Moreover, the activities of detoxification enzymes of P. xylostella were suppressed by treatment with insecticide-loaded NPs, which showed that NPs could also be involved in reduction of enzymes. Furthermore, the entering of FL-SiO2 NPs into the midgut of P. xylostella was confirmed by confocal laser scanning microscope (CLSM). For comparison, P. xylostella under treatment with water as control was also observed under CLSM. The control exhibited no fluorescent signal, while the larvae treated with FL-SiO2 NPs showed strong fluorescence under a laser excitation wavelength of 448 nm. The reduced enzyme activities as well as higher cuticular penetration in insects indicate that the nano-based delivery system of insecticide could be potentially applied in insecticide resistance management.
