A Study of the larvacide efficacy of Insect Growth Regulator (IGR) with the, active ingredient
pyriproxifen 0.5%, has been conducted in the laboratory of the Institute for Vector andReservoir
Control Research and Development, Salatiga City, Central Java Province. The study was caried out
on December 2009, performed as laboratory scale trial using plastic trays (20x30 cm). Each tray
contains5liters ofwateraddedwithpyriproxifenconcentration2g/m3. Atotal 25earlythird instar
larvae ofmalaria vector An.aconituswere placed in each treated tray (10 replicates) as wellas
untreated trays as the control (5 replicates). The larvae mortality was daily counted and recorded. The
aim of the study was to evaluate the efficacy of IGRlarvicide (a.i. pyriproxifen0,5%, granule
formulation), against malaria vector larvaeAn.aconitusin the laboratorycondition. The result was
revealed that IGR(pyriproxifen0,5%) was effective caused100%emergenceinhibition and made 13
days longer viability ofAn.aconitus in immature stagesdevelopment long life of An.aconitus
immature stagesdevelopment.Some larvae were found growing to be adult with various defected due
touncompletedmetamorphosis,such as their smallwings and legs are attached to pupal skin
