Potential larvicidal bioefficacy of copper sulfide-based hybrid nanoemulsions of eucalyptus oil against (Linnaeus).

Background & Objectives: Nanotechnology, an emerging field, has acquired considerable attention for the control of vectors. The present study aimed to synthesize, characterize copper sulfide- and eucalyptus oil-based hybrid nanoemulsions and investigate their larvicidal potential against Aedes aegypti by studying larvicidal bioassay, morphological aberrations, histopathological alterations, biochemical analysis and evaluation of risk assessment in non-target organisms.

Methods: Hybrid nanoemulsions were prepared by mixing aqueous copper sulfide nanoparticles (CuSNPs) with non-polar eucalyptus oil in five ratios (1:1, 1:2, 1:3, 1:4 and 1:5) by sonication, screened and characterized using Transmission electron microscopy (TEM).

Larvicidal potential and residual activity effect of kinnow peel oil against L.

Background & Objectives: Transmission of dengue virus by Aedes aegypti mosquito is one of the major global health concerns. The present study was aimed to explore the larvicidal potential of oil extracted from kinnow peel waste to be used as an efficient, economic and safe agent against Ae. aegypti.
