Evaluation of Picaridin Treated Fabrics for their Protection Against Mosquito Bites in Comparison with the Current US Army Permethrin Factory-Treated Uniform
Abstract
Development of next-generation repellent-treated uniforms is important in order to protect service members against bites of arthropod disease vectors. In this study, fabrics treated with two concentrations of microencapsulated picaridin repellent were evaluated for protection against the biting and landing activity of Aedes aegypti and Anopheles gambiae mosquitoes. The results were compared with the protection provided by the current permethrin treated uniform. Uniform fabrics tested included two concentrations of picaridin, permethrin treated and untreated uniform, and net. Twenty mosquitoes were added to each assay for ten minutes, landing counts observed and later examined for blood-feeding. The picaridin treated fabrics demonstrated the reduction of mosquito landing and biting activity. The fabrics provided 100 percent bite protection against Ae. aegypti and significantly reduced the landing counts. Landing counts and blood-feeding rates were significantly reduced by the picaridin treatment but it was not significantly different from the protection provided by the current permethrin treatment.
