Vector control plays a key role in prevention and control of major vector-borne diseases. Repellents are the first line
of defence against the epidemics of vector-borne diseases. Synthetic mosquito repellent used for control of vectors
cause irreversible damage to ecosystem and are non-degradable in nature. The uses of biologically-active plant
materials with anti-mosquitocidal properties are attracted in recent years, because of their biodegradable nature and
being relatively safer to human and other non-target organism in the environment. Hence the present study aimed to
produce a novel herbal cream as a mosquito repellent. The leaves included for the study are papaya (Carica
papaya), Guava (Psidium guajava), Tawa tawa (Euphorbia hirta) and Neem (Azadirachta indica). The extracts were
prepared by different methods such as Maceration, soxhlet and shaker extraction process and also with different
solvents Ethanol, Ethyl acetate, Acetone. These extracts were qualitatively and quantitatively analysed for active
ingredient. Ethyl acetate (soxhlet) was found to be high concentration of Quercetin. In vitro antioxidant properties
were evaluated by reducing power assay method and ethyl acetate (soxhlet) extract were shown to posses high anti
oxidant activity. This extract was chosen to formulate cream. Piperine extracted from black pepper was used as an
additive in cream formulation. The prepared cream was tried on mosquitoes kept in fabricated mosquito cage. In the
study it was observed that the mosquitoes moved towards the corner of the cage which indicates the repellent
action. The study can be further extended to screen the toxic effect through animal studies to bring it as a potent safe
and eco-friendly mosquito repellent.
