Abstract
The present specification discloses natural repellent compounds, and isomeric forms, structural analogs and derivatives of the said compounds, having repellent activity against mosquitoes and other blood-sucking arthropods, compositions comprising such repellent compounds, methods of screening for such repellent compounds, methods of reducing mosquito bites on an individual and methods of reducing mosquito infestation to a location.
Claims20
A method of repelling an insect and/or an arachnid, the method consisting essentially of applying a composition to an animal, a human, a substrate and/or a location, the composition consisting essentially of an insect repelling amount and/or an arachnid repelling amount of a carvacrol compound, an insect repelling amount and/or an arachnid repelling amount of a cumin compound and an insect repelling amount and/or an arachnid repelling amount of a cinnamate compound, wherein the carvacrol compound is carvacrol, thymol or combinations thereof, the cumin compound is cumin alcohol, cuminic acid or combinations thereof;
- and the cinnamate compound is methyl cinnamate, ethyl cinnamate, butyl cinnamate, isobutyl cinnamate, N-butyl cinnamate, isopropyl cinnamate, E-cinnamyl acetate, cinnamaldehyde, E-cinnamaldehyde, Z-cinnamaldehyde, methoxycinnamaldehyde or combinations thereof, wherein application of the composition to the animal, the human, the substrate and/or the location repels the blood-feeding arthropod from the animal, the human, the substrate and/or the location.
A method of reducing bites of a blood-feeding arthropod in an animal or a human, the method consisting essentially of applying a composition to the animal or the human, the composition consisting essentially of a blood-feeding arthropod repelling amount of a carvacrol compound, a blood-feeding arthropod repelling amount of a cumin compound and a blood-feeding arthropod repelling amount of a cinnamate compound, wherein the carvacrol compound is carvacrol, thymol or combinations thereof, the cumin compound is cumin alcohol, cuminic acid or combinations thereof;
- and the cinnamate compound is methyl cinnamate, ethyl cinnamate, butyl cinnamate, isobutyl cinnamate, N-butyl cinnamate, isopropyl cinnamate, E-cinnamyl acetate, cinnamaldehyde, E-cinnamaldehyde, Z-cinnamaldehyde, methoxycinnamaldehyde or combinations thereof, wherein application of the composition repels the blood-feeding arthropod from the animal or the human, thereby reducing bites of blood-feeding arthropods.
A method of reducing an infestation of a blood-feeding arthropod in a location, the method consisting essentially of applying a composition to the location, the composition consisting essentially of a blood-feeding arthropod repelling amount of a carvacrol compound, a blood-feeding arthropod repelling amount of a cumin compound and a blood-feeding arthropod repelling amount of a cinnamate compound, wherein the carvacrol compound is carvacrol, thymol or combinations thereof, the cumin compound is cumin alcohol, cuminic acid or combinations thereof;
- and the cinnamate compound is methyl cinnamate, ethyl cinnamate, butyl cinnamate, isobutyl cinnamate, N-butyl cinnamate, isopropyl cinnamate, E-cinnamyl acetate, cinnamaldehyde, E-cinnamaldehyde, Z-cinnamaldehyde, methoxycinnamaldehyde or combinations thereof wherein application of the composition to the location repels the blood-feeding arthropod from the location, thereby reducing the infestation.
