Article Abstract
Using nanotechnology to develop new formulations of pesticides is considered a possible option in enhancing the efficiency, safety, and photostability of pesticides under various climatic conditions. In the present study, two novel nanoformulations (NFs) were successfully prepared based on nano-delivery systems for emamectin benzoate (EMB) by loading it on cellulose nanocrystals (CNCs) and silicon dioxide nanoparticles (SNPs) as carriers through a freeze-drying method. The synthesized nanoformulations were examined using field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and dynamic light scattering (DLS). The results showed that SNPs and CNCs had a loading efficiency of 43.31% and 15.04% (/) for EMB, respectively, and could effectively protect EMB from photolysis under UV radiation. The LC values for EMB + SNPs, EMB + CNCs, and EMB commercial formulation against were 0.01, 0.05, and 0.31 μg/mL, respectively, indicating that both NFs were more effective than the EMB commercial formulation. This work seeks to develop new nano-carriers for potential applications of pesticides in plant protection, which will reduce the recommended dose of pesticides and thereby decrease the amount of pesticide residue in food and the environment.

Excessive use of agrochemicals results in contamination of water due to runoff or leaching. Insecticide induced-hormesis, a phenomenon characterized by low dose stimulation following exposure to insecticide, is crucial to insect pest resurgence. In this study, the effects of low or sublethal concentrations of emamectin benzoate and thiamethoxam on biological traits and genes expression were investigated for yellow fever mosquito, Aedes aegypti following 48 h exposures.

Air pollution caused by pesticide drift poses a significant environmental health risk. The lungs are directly targeted by airborne pesticide exposure via inhalation; however, their inhalation toxicological data are poorly understood. In the present study, we evaluated the combined toxicity and interactions of lambda-cyhalothrin and its binary mixtures with eight insecticides at a concentration ratio of 1:1 in the non-small-cell lung cancer A549 line cells.

Insecticides are widely used to protect agricultural and plantation products from pests and plant-disrupting organisms. Prior to market distribution, pesticide-containing products must undergo safety evaluations, including assessments of potential skin and eye irritation and allergic responses. In this study, we conducted one of the first comparative in vivo evaluations of commercial insecticidal formulations containing cypermethrin (Gusano 300 EC), pymetrozine (Vorum 50 WG), and indoxacarb-emamectin benzoate (Endorse Plus 160/20 OD) using internationally recognized protocols based on OECD 404 (skin irritation), OECD 405 (eye irritation), and OECD 406 (skin sensitization).

While emamectin benzoate (EB) remains a key insecticide against , significant resistance has developed, compromising its effectiveness. Identifying response genes and mutations is critical for resistance management. Here, genome resequencing and transcriptome analysis of EB-resistant (EB-R) and EB-susceptible (EB-Sus) strains of identified 177 candidate genes.

The avermectin family of anthelmintics is largely considered to lack antibacterial activity against gram-positive and gram-negative bacteria. Here, we screened six avermectins (ivermectin, eprinomectin, doramectin, abamectin, selamectin, and emamectin benzoate) and a structurally related milbemycin (moxidectin) for antibacterial activity against a panel of representative gram-positive and gram-negative bacteria. We report that emamectin benzoate exhibited activity against several species of gram-positive bacteria, whereas selamectin was active against and .
