Article Abstract
Unlabelled: (MDMV) is one of the most serious viruses of sweet corn. Utilising the process of RNA interference, the exogenous introduction of small RNA molecules mimicking virus-derived small interfering RNA (siRNA) into the plant prior to infection triggers the antiviral RNA silencing effect, thereby promoting more effective antiviral protection. Hence, a treatment with MDMV-derived small RNA was applied to sweet corn plants one day before MDMV virus inoculation. ALEXA FLUOR®488 fluorophore-bound exogenous siRNA was successfully detected inside intact sweet corn cells using confocal fluorescence microscopy. Furthermore, it was demonstrated that the exogenous siRNA treatment led to a notable upregulation of the , , , , , , , , and genes within 24 h of the treatment. Overall, exogenous siRNA treatment resulted in better virus control of infected sweet corn plants, as indicated by the lower viral RNA and coat protein levels compared to the infected group without pre-treatment.

Mosquito-borne diseases pose significant public health challenges, necessitating the development of effective and sustainable vector control strategies. This study investigated the feeding preferences of 4 mosquito species (Aedes aegypti Linnaeus, Aedes albopictus Skuse, Culex quinquefasciatus Say, and Anopheles quadrimaculatus Say) for various fruit juices using a home-made choice chamber. We also assessed the impact of combining biogents lure and boric acid into attractive toxic sugar baits to enhance mosquito attraction and mortality.

Phenolic compounds are secondary metabolites widely distributed among plants, with bioactive properties, especially antioxidant activity. The search for sustainable extraction methods has driven the use of natural deep eutectic solvents (NaDESs), formed by combinations of natural compounds, such as organic acids, sugars, alcohols, and amino acids. This study optimized NaDES (sorbitol, citric acid, and glycine) efficiency and compared it to that of 70% methanol solution in extracting total soluble phenolic compounds (TSPCs) from six flours matrices-corn, buckwheat, biofortified orange sweet potato, red lentil, Sudan grass, and chickpea-before and after thermoplastic extrusion cooking.

Neonicotinoids (NNIs) raise global concern due to their substantial soil residues and potential health risks to animal and human health. High water solubility and low soil adsorption enhanced vertical and horizontal migration of NNIs. However, understanding of NNIs' three-dimensional distribution in soils and influencing factors remains limited, limiting accurate risk assessment and remediation strategies for agriculture ecosystems.

Background: Intensive agricultural production leads to the reduction of soil carbon (C) and nitrogen (N) reserves, and organic material mulching (OMM) can improve microbial community structure and promote C and N accumulation. The multi-cropping system based on legumes can provide abundant organic mulching material and improve soil quality, but the mechanism by which OMM provides ecological benefits via C and N cycling in this system is still unclear.
Methods: In this study, a field experiment of organic mulch under the triple-cropping system of faba bean ( L.
