T

he emergence of mosquito vector borne diseases is considered as a perpetual problem globally in tropical countries.

Outbreak of several diseases such as chikungunya, zika viral infection and dengue fever has created a massive threat

towards living population. Frequent usage of synthetic insecticides like DDT eventually had its adverse harmful effects on

humans as well on the environment. Since there are no perennial vaccines, prevention, treatment or drugs available for these

pathogenic vectors, WHO is more concerned in eradicating their breeding sites effectively without any side effects on humans

and environment by approaching plant derived natural eco-friendly bio-insecticides. The aim of this study is to investigate

the larvicidal potential

Cinnamomum verum

essential oil (CEO) loaded niosomes were prepared using trans-membrane pH

gradient method using cholesterol and surfactant variants of Span 20, 60 and 80 and treated against II to IV instar larvae of

Aedes aegypti, Anopheles stephensi

and

Culex quinquefasciatus

. The synthesized CEO loaded niosomes were characterized by

zeta potential, particle size, Fourier Transform Infrared Spectroscopy (FT-IR), GC-MS and SEM analysis to evaluate charge,

size, functional properties, composition of secondary metabolites and morphology. The Z-average size of the formed niosomes

was 1870.84 nm and had good stability with zeta potential -85.3 meV. The entrapment efficiency of the CEO loaded niosomes

was determined by UV-Visible Spectrophotometry. Evaluation of synthesized niosomes against gram-positive (

Bacillus subtilis

)

and gram-negative (

Escherichia coli

) bacteria and fungi (

Aspergillus fumigatus

and

Candida albicans

) at various concentrations

were assessed for its bio-potency. The larvicidal activity was evaluated at various concentrations for 24 h and LC50 and LC

90 values were calculated. The results exhibited that CEO loaded niosomes has greater efficiency against mosquito larvicidal

property and also the results suggest that niosomes could be used in various applications of biotechnology and drug delivery

systems with greater stability by altering the drug of interest.
