Summary: This paper evaluated the feasibility of a nano-insecticide containing sweet orange essential oil as the active ingredient against Aphis gossypii in real conditions. The developed nano-insecticide showed good aphicidal activity in laboratory and field trials, but high concentrations showed phytotoxic effects on citrus plants. Careful consideration of the side effects is necessary for successful field application.

Summary: In this study, a total of 44 insect kinin analogs with modification at the Phe(2) position were designed and synthesized. Bioassays revealed that nine analogs exhibited better aphicidal activity than the lead analog IV-3, with compound L-25 showing excellent aphicidal activity and low toxicity to bees. Furthermore, a reliable 3D-QSAR model was established, providing valuable insights for structural optimization.

Summary: In this study, it was found that the increased resistance of whitefly to imidacloprid is associated with the overexpression of CYP6DW3 and CYP6DW5v1 genes, and knockdown of these genes weakened the resistance. Moreover, it was shown that the CYP6DW3 protein can metabolize 14.11% of imidacloprid in vitro. These findings enhance our understanding of insect resistance mechanisms and contribute to the development of integrated pest management frameworks.

Summary: A gravity-fed, cometabolic biofiltration system was developed to degrade 1,4-dioxane in drinking water. Results showed that trace levels of 1,4-dioxane can be sustained degraded in biofilters using n-butane as primary substrate, and filter media properties and EBCT affect the efficiency of biofiltration.

Summary: This study provides evidence on the anaerobic biodegradation of TBBPA in domestic sewage, showing that the removal of TBBPA involves acidogenesis and methanogenesis processes. Through continuous operation of reactors for over 100 days, it was found that TBBPA degradation occurs during acidogenesis via cometabolism supported by non-specific enzymes and dehalorespiration metabolism established by electron donors.

Summary: This review focuses on the metabolic activities, mechanisms, and enzymatic activities involved in the biotransformation of organic micropollutants in wastewater treatment plants under different redox environments. Common methodologies for studying such enzymes, including in vitro enzyme assays, enzymatic inhibitors, analysis of transformation products, and various -omic techniques, are discussed. Perspectives on major challenges and future research requirements to enhance the biotransformation of organic micropollutants are proposed.

Summary: Neonicotinoids are widely used pesticides and have been shown to be harmful to many organisms. They bind to human nicotinic acetylcholine receptors and cause cellular toxicity. In a recent study, the effects of imidacloprid and other neonics on cellular protein expression were examined, suggesting a role for protein synthesis and transcriptional regulation in neonic-mediated neurotoxicity.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants associated with carcinogenic, mutagenic, and teratogenic health effects. Analyzing PAHs and their transformation products often requires extensive sample preparation and analytical techniques. Excitation-emission matrix (EEM) fluorescent spectroscopy with parallel factor analysis (PAR-AFAC) is a method that eliminates the need for extensive sample preparation and separation techniques. This study demonstrates the use of EEM-PARAFAC to monitor phenanthrene degradation and formation of metabolites.

Summary: This study investigated the biotransformation of organic micropollutants under anoxic conditions using a heterotrophic denitrifying bioreactor. The results showed that increasing nitrogen loading rates improved the removal efficiency of erythromycin, roxithromycin, and bisphenol-A, and specific bacterial taxa were identified as indicators related to the biodegradation of these compounds. The study also found that increasing primary metabolic activity did not enhance the removal rates of the organic micropollutants, suggesting that bacterial composition is more influential than cometabolism.

Summary: The novel pyridinamide insecticide Flonicamid poses potential risks to aquatic environments due to its wide application in agriculture and high solubility in water. Ensifer adhaerens CGMCC 6315 was found to efficiently transform Flonicamid into N-(4-trifluoromethylnicotinoyl) glycinamide using nitrile hydratases PnhA and CnhA, making it a promising candidate for bioremediation of Flonicamid contamination in surface water. Structural homology modeling suggested that residue beta-Glu56 may play a key role in the differential enzyme activity between PnhA and CnhA.

Summary: A novel isolated bacterium, Pseudomonas stutzeri CGMCC 22915, was found to rapidly degrade Sulfoxaflor (SUL), a sulfoximine insecticide, into SUL-amide. This bacterium effectively facilitated SUL degradation in soil and surface water. Additionally, a nitrile hydratase with a different gene orientation, PsNHase, was discovered to transform SUL and other nitrile-containing insecticides into their respective amides. This research provides potential solutions for the bioremediation of SUL in contaminated soil and surface water.

Summary: In this study, it was found that Pseudaminobacter salicylatoxidans CGMCC 1.17248 rapidly converted SUL into X11719474 via hydration pathway mediated by two nitrile hydratases. P. salicylatoxidans CGMCC 1.17248 showed high efficiency in degrading SUL, and cell immobilization further improved the degradation efficiency.
