Aedes aegypti L., is a serious global threat to human health as a vector for spreading several deadly diseases. Plant extracts provide an efficient and ecofriendly alternate to manage this menace. The sublethal concentrations i.e. 50 and 60 ppm of nanoemulsified eucalyptus oil evaluated against 4th instar (L4) Ae. aegypti larvae resulted in 16.67± 1.67 and 8.33± 1.67% larval survival followed by a significant delay in duration of various developmental stages and decrease in % pupal formation and their survival. Thus, decline in % emergence along with significant reduced body size and longevity were observed in comparison to control and vehicle-control emerged adults. These results reveal the potential of such nanoemulsified oils to be used as phytochemical agents for the sustainable control of Ae. aegypti.
