The invasive, soft-skinned fruit dipteran pest Drosophila suzukii (Matsumura), commonly known as the spotted-wing drosophila (SWD), causes severe damage to the blueberry production system in several western countries. Current management relies on frequent insecticide applications timed with fruit ripening, which increases resistance risk and environmental concerns. In this study, we investigated 5-hydroxymethylfurfural (5-HMF), a sugar derivative volatile identified by gas chromatography-mass spectrometry (GC-MS) analysis from a novel D. suzukii attractant Decoy Attract and Kill (A&K) (Batch no. 24026021), that exhibited strong behavior-disrupting effects on D. suzukii. We then evaluated the D. suzukii behavioral disruption of 5-HMF with electroantennography (EAG), Drosophila Activity Monitor (DAM), and laboratory and field oviposition trials. Moreover, the toxicity of 5-HMF and its developmental delay were also assessed. Exposure to the 2 mM Decoy A&K and increasing concentrations of 5-HMF resulted in an increased residence time, suggesting prolonged attraction or orientation-change behavior. Flies exposed to ≥ 10 mM 5-HMF showed significantly lower egg counts in blueberries and exhibited increased mortality. Additionally, ≥ 5 mM of 5-HMF showed a clear dose-dependent developmental delay, from the egg to pupal and adult stages. These findings suggest that 5-HMF acts as both a behavioral and developmental disruptor for D. suzukii. Thus, 5-HMF can serve as a novel A&K candidate supporting integrated pest management (IPM) strategies for sustainable control of D. suzukii.

Wood is a sustainable carbon-storage material that is widely used in construction and packaging. However, its intrinsic flammability restricts its application. Existing flame-retardant modifications either rely on toxic chemicals or generate byproducts. In contrast, bioinspired microbially induced calcium carbonate precipitation offers a solution to this challenge. In this study, a facile method was developed for the in situ growth of Bacillus mucilaginosus (B.m.) on the wood porous structure. The B.m. solution exhibited a significantly low surface tension and a favorable wettability on wood surfaces. This is attributed to the extracellular polymeric substances secreted by the strain, which promote its deep penetration into wood structures without relying on vacuum or pressure-assisted conditions. During ambient drying, B.m. utilizes carbonic anhydrase to capture atmospheric CO2, inducing CaCO3 deposition in cell lumens of wood and formed mineralized wood. Morphological and chemical characterizations confirmed the formation of well-crystallized CaCO3 without altering the wood appearance. The B.m.-treated wood has a higher residual weight, delayed thermal decomposition, reduced heat release, and faster self-extinguishing ability, achieving enhanced flame retardancy. This waste-free and energy-efficient process can achieve CO2 sequestration, aligns with zero-waste city goals, and has broad potential in fire-safe wood applications.

Potential of ethyl acetate and acetone extracts from Montrichardia linifera leaves: Chemical characterization, in vitro study, molecular docking and ADME-TOX.

Vitex negundo L. (Verbenaceae) is a well-known medicinal plant used in traditional medicine for the treatment of inflammatory, microbial, and oxidative stress-related disorders. The present study aimed to evaluate antibacterial and antioxidant activities of Vitex negundo leaf extracts, along with their chemical characterization using Fourier transform infrared (FT-IR) spectroscopy and gas chromatography-mass spectrometry (GC-MS). Antibacterial activity of acetone, methanol, and aqueous extracts was assessed by agar well diffusion method against four bacterial strains. The acetone extract exhibited notable antibacterial activity, particularly against Bacillus cereus and Bacillus subtilis. Antioxidant potential was evaluated using the DPPH radical scavenging assay, where acetone and methanol extracts demonstrated the highest activity in a dose-dependent manner. FT-IR analysis confirmed the presence of various functional groups associated with bioactive compounds. GC-MS profiling identified 24 compounds in the acetone extract and 20 compounds in the methanol extract, with major constituents such as isoambreinolide, catechol, n-hexadecanoic acid, kojic acid, karanjin, and phytol, many of which are known for their antimicrobial, antioxidant and anti-inflammatory properties. Overall, the findings indicate that Vitex negundo leaves are rich in bioactive phytochemicals and possess significant antibacterial and antioxidant activities, supporting their traditional medicinal use and highlighting their potential for pharmaceutical applications.
