Abstract
Two ofthemostimportantchallengesfacinghumanityinthe21stcenturycomprisefoodproductionand disease control.Eco-friendlycontroltoolsagainstmosquitovectorsandagriculturalpestsareurgently needed. Insecticidalproductsofmarineoriginhaveahugepotentialtocontrolthesepests.Inthisre- search, wereportedasingle-stepmethodtosynthesizesilvernanoparticles(AgNP)usingtheaqueous leaf extractoftheseaweed Hypnea musciformis, acheap,nontoxicandeco-friendlymaterial,thatworked as reducingandstabilizingagentduringthebiosynthesis.TheformationofAgNPwasconfirmed by surface plasmonresonancebandillustratedinUV–vis spectrophotometer.AgNPwerecharacterizedby FTIR, SEM,EDXandXRDanalyses.AgNPweremostlysphericalinshape,crystallineinnature,withface- centeredcubicgeometry,andtheirmeansizewas40–65 nm.Lowdosesof H. musciformis aqueousex- tract andseaweed-synthesizedAgNPshowedlarvicidalandpupicidaltoxicityagainstthedenguevector Aedes aegypti and thecabbagepest Plutella xylostella.
