Abstract：Objective To investigate the efficacy of slow-release mosquito repellent mats.Methods Porous materials were prepared via concentrated emulsion template,and the slow-release mosquito repellent mats were obtained after pyrethroid load.Natural volatilization rate curve of mosquito repellent mats under room temperature was studied,and the relationship between volatilization rate and structure of porous material was discussed.The slowrelease mosquito repellent sample was fixed on the fan hood,and field efficacy was evaluated according to the national standard (GB/T 13917.10-2009).Scanning electron microscopy(SEM) was used to observe the surface morphology of mosquito repellent mat.Results Each slow-release mosquito mat was loaded with 500 mg transfluthrin.Smples C,D,E,F,G and H showed excellent slow-release property and mosquito repellent performance.The surface morphology analysis showed the natural volatilization rate of slow-release mosquito repellent mats at room temperature was related to the porous structure.Conclusion Fan driven slow-release repellent mats have excellent long-lasting mosquito repellent ability to meet the daily needs of mosquito repellent.
