Method for reducing parasite burden in a mosquito
Described herein are methods and compositions for reducing transmission of Plasmodium to a female mosquito. Aspects of the invention relate to contacting to a mosquito with a Plasmodium transmission blocking compound. Another aspect of the invention relates to a surface coated with a Plasmodium transmission blocking compound.
1 . A method for reducing transmission of Plasmodium to a female mosquito, the method comprising: contacting a female mosquito with a composition comprising an effective amount at least one Plasmodium transmission blocking compound, wherein the at least one Plasmodium transmission blocking compound is selected from the group consisting of atovaquone (ATQ), acequinocyl (ACE), and hydramethylnon (HYD), wherein the survival rate of the mosquito is not impacted by the contacting.
2 . The method of claim 1 , wherein the contacting comprises topical contacting or tarsal contacting.
3 . The method of claim 2 , wherein the tarsal contact comprises tarsal absorption or ingestion of the at least one Plasmodium transmission blocking compound, wherein the at least one Plasmodium transmission blocking compound is selected from the group consisting of atovaquone (ATQ), acequinocyl (ACE), and hydramethylnon (HYD).
4 . The method of claim 1 , wherein the contacting occurs on a surface coated with the at least one Plasmodium transmission blocking compound, wherein the at least one Plasmodium transmission blocking compound is selected from the group consisting of atovaquone (ATQ), acequinocyl (ACE), and hydramethylnon (HYD).
5 . The method of claim 4 , wherein the surface is selected from the group consisting of: an interior wall of a building; an exterior wall of a building; a bed net; an indoor fabric; an outdoor fabric; clothing; inside a trap; and outside a trap.
6 . The method of claim 1 , wherein reducing transmission inhibits the zygote/ookinete transition of Plasmodium development or in the inhibition of Plasmodium ookinete development.
7 . The method of claim 1 , wherein the female mosquito has been infected with Plasmodium prior to contacting.
8 . The method of claim 1 , wherein the composition further comprises at least one of a cuticular/tarsal uptake enhancer and a cytochrome P450 inhibitor.
9 . The method of claim 8 , wherein the cuticular/tarsal uptake enhancer comprises a mixture of the methyl esters of saturated and unsaturated C10-C26 fatty acids or rapeseed methyl ester.
10 . The method of claim 8 , wherein the cytochrome p450 inhibitor is at least one of piperonyl butoxide and 1-aminobenzotriazole.
