Mitigating climate change can be achieved by opting for sustainable, plant-based materials instead of relying on hazardous chemicals that come with various side effects. Various natural plant extracts find widespread application in synthesizing insect-repellent coatings, particularly industries such as paint manufacturing. The increasing demand these coatings has led us to out the effects different efficient preparation paints more advanced impacts and low cost. For this purpose, zinc nanoparticles Eucalyptus globulus L. its were used study due their remarkable biocidal antimicrobial activities. extract was prepared process oven-drying heating followed filtration. Then, they subjected phytochemical tests performed which material did not contain flavonoids glycol. comparison size visible during weighing found 4.451 mg. Advanced characterization techniques like FTIR, UV spectroscopy, particle analysis adopted extract. FTIR reported lie range 1000–1800 cm−1. On other hand, results spectroscopy showed absorption peaks around 300 nm. produced integrated into formulations impart antibacterial characteristics. Painted panels exhibited notable efficacy, presenting an inhibition zone 0.7 cm Escherichia coli 0.3 Staphylococcus aureus when utilizing biocide. Plant yielded zones 1 1.2, while aqueous resulted 0.2 0.5, respectively. A thorough evaluation paint's color attributes, including ΔL, Δa, Δb, ΔE, indicated noteworthy differences. CMC ΔE values from trials exceeded 1, indicating a substantial shade. batches containing E. lighter specifically green yellow colors. Their insect repellant activity tested using mosquitos Aedes aegypti age 4–5 weeks, revealing 61 % effective period, greater than 7 observed non-biocidal formulations. responded best towards mosquitoes terms repellency ultimate target achieved.

ABSTRACT Mosquitoes act as biological carriers spreading numerous vector borne diseases globally. The present research aimed to study the effect of essential oils (EOs) from Pentanema indicum (L.) Y. Ling and Chromolaena odorata R.M. King & H. Rob against Aedes aegypti , Anopheles stephensi Culex quinquefasciatus mosquitoes. Concentrations 3.125, 6.25, 12.5 25 50 ppm were tested for their mosquitocidal properties. oil (EO) P. demonstrated promising ovicidal activity, achieving 100% efficacy Ae.

Abstract The objective of this study is to determine the larvicidal activity essential oils (EOs) extracted from three plants genus Artemisia against mosquito Culex pipiens ( C. ) using in vitro and silico studies. A total number 20 third- fourth-instar larvae were exposed various concentrations plants. LC 50 90 values tested EOs determined Probit analysis. In addition, sensitivity these was compared a standard insecticide, temephos, under laboratory conditions. Furthermore, assessments carried out on major constituents help understand explain acquired vivo results. Gas chromatography analysis identified compounds as d -limonene β-pinene for flahaultii , camphor borneol Artemisia. aragonensis artemisia ketone caryophyllene annua . A. oil showed highest efficacy larvae, followed by with average activity. contrast, EO, composed high percentage monoterpenes, least active. Docking simulation indicated that several studied ligands had promising binding scores within receptor’s site reference insecticide temephos. obtained results allow us conclude species endemic Morocco, an excellent means controlling
