Biosynthesis and characterization of selenium and silver nanoparticles using Trichoderma viride filtrate and their impact on Culex pipiens

Green Processing and Synthesis, Год журнала: 2024, Номер 13(1)

Опубликована: Янв. 1, 2024

Abstract Some of the significant globally prevalent vector-borne illnesses are caused by Culex pipiens . Synthetic pesticides have been widely utilized to eradicate C. , which has led a number health risks for people, insect resistance, and environmental contamination. Alternative strategies therefore vitally needed. In current investigation, Trichoderma viride fungal culture filtrate was used create selenium silver nanoparticles (SeNPs AgNPs, respectively) test them on larvae in their fourth instar stage. The death rate increased significantly when SeNP AgNP concentrations increased, according results. SeNPs AgNPs affected developmental detoxification enzymes at 24 h after being treated with sublethal concentration tested NPs. As result insecticidal effect larvae, considered effective promising larvicidal agents.
