- Background. Aedesaegyptiisthe main vector of DF/DHFin Indonesia. Interruptingthelifecycle of thevectoris main strategytoreducetheincidence of DF/DHF. The breeding of themosquitoiseliminatedbylarvicide, especiallysyntheticlarvicide. The problemsconsist of vectorresistanceandenvironmentalpollution. Therefore, itisessentialtosearch for alternativelarvicide, for instanceZingiberzerumbet as natural larvicide. Objectives.Toexplorelarvicidaleffect of Zingiberzerumbetrootswith ethanol extract. Tofindout LC50and LC90 of the athanol extract against 3rd/4th instarlarvae of Aedesaegypti.Tofindouttherelationbetweenvariety of the extract ethanol doseandlarvaemortality. Methods.Thisresearchisquasiexperimentalstudyusing WHO (2005)guidance. 3rd/4th instarlarvaedividedinto 7treatmentgroupsand 1 controlgroup. Eachgroupcontains20 larvaewith 3 timesreplicationin 100 ml solution. Larvaemortalitywascountedafter 24 hours of exposureandthe data wasanalyzedusingprobitanalysis. Result.LC50and LC90valueswere 107.23 ppmand 183.1 ppm. The probitregressionlineobtainedisY = -6.2 + 5.52X. Conclusion.Ethanolextract of Zingiberzerumbetroots has larvicidalactivity against 3rd/4th instar of Aedesaegyptilarvae. LC50and LC90valueswere107.23 ppmand183.1 ppm. The increasingdose of the ethanol extract increaseslarvaemortality. Keyword.Aedesaegypti, Zingiberzerumbet, botanical larvicide, probitanalysis.
