The growing threat of vector-borne diseases and environmental pollution has prompted nanotechnology based investigations. The present study aimed to use one of the nanotechnological applications with larvicidal potential against Aedes aegypti by preparing aqueous hybrid nanoemulsion of zinc sulfide nanoparticles and Eucalyptus globulus oil. The mean droplet size of prepared and most stable hybrid nanoemulsion (9.5 ppm) was found to be 60 ± 10.00 nm. The hybrid nanoemulsion exhibited LC50 and LC90 values of 7.63 and 9.22 ppm. The findings obtained from larvicidal assay were corroborated with SEM, histological and biochemical profiles of Aedes larvae after treatment. Optimum larvicidal potency was observed under simulated conditions after 48 hrs of exposure. Larvicidal concentration of nanohybrid was found to be non-toxic to Scapholebris kingi. Thus, the following research explains larvicidal efficacy of zinc sulfide based hybrid nanoemulsion formulated during the present study is a step towards safe and efficient approach against Aedes aegypti.
