Development of insecticide resistance against the chemical synthesized insecticides and high operational cost of secondary plant resources as well as other vector controlling strategies, intake a step towards a new controlling tool with urgent basis. The present study was aimed to develop an alternative approach with low cost and healthy environmental aspects to control most prominent dengue vector in rural areas by using green synthesis of iron nanoparticles of Eucalyptus citriodora (L.) The synthesized iron nanoparticles (FeNPs) were found to be amorphous in morphology. While FeNPs were tested against Aedes albopictus (Skuse) third instar larvae and adult, it was found that LC50 and LC90 was recorded 11.269 and 23.076 ppm while KDT50 and KDT90 were calculated 14.253 and 34.657 minutes respectively. The study indicate that use of FeNPs as dengue vector control would be better approach with ecofriendly and economically.
