The observed mortality was significantly more than expected in the absence of any interaction (80 % vs 41 % and the knock-down effect was maintained, providing an effective barrier against susceptible mosquitoes. A significant synergism was observed with a mixture containing 25 mg/m2 of bifenthrin (half the recommended dosage for treated nets and 6.25 mg/m2 of carbosulfan (about 2 % of the recommended dosage. The mixtures were sprayed on mosquito net samples and their efficacy were tested against a susceptible strain of Anopheles gambiae, the major malaria vector in Africa.
This study presents the results obtained with insecticide mixtures containing several proportions of bifenthrin (a pyrethroid insecticide and carbosulfan (a carbamate insecticide. One strategy for resistance management would be to treat mosquito nets with a mixture associating two insecticides having different modes of action. Unfortunately, some malaria vector species have developed resistance to pyrethroids and the lack of alternative chemical categories is a great concern. Insecticide mixtures for mosquito net impregnation against malaria vectorsĭirectory of Open Access Journals (Sweden)įull Text Available Insecticides belonging to the pyrethroid family are the only compounds currently available for the treatment of mosquito nets. The theory of net analyte signal was originally derived from classical least squares. In this paper a theory for their use in inverse regression is developed.
