Repellents and Treated Fabrics Researchers in the 1960’s from the U.S. Army Medical Research Unit conducted a comparative efficacy test of Diethyltoluamide skin-application and M-1960 impregnated-clothing against mosquitoes in the nipah palm-mangrove swamps of Malaya (30). In this study, it was shown that the combination of skin repellent and clothing treatment provided the best protection against mosquito bites. Use of skin repellent was effective at preventing bites to the skin but this resulted in an increase in mosquitoes landing on the untreated uniform and biting through it. Solely treating the uniform with repellent had a similar effect, driving the mosquitoes to the unprotected skin areas. This experiment required the use of volunteers to stand in the swamps and act as live bait for wild mosquitoes to land on them.
A group of researchers from the Letterman Army Institute of Research conducted a study of the effects of weathering on fabrics treated with permethrin (11). In this study, permethrin-impregnated and untreated fabrics were evaluated for their toxic and repellent effects against Anopheles stephensi and Aedes aegypti after both types of fabrics were subjected to accelerated weathering for 9 weeks, under a simulated wet/tropical environment. This study showed that the toxic (knock-down) effect of permethrin-impregnated fabrics diminished rapidly after 1 week while the repellent effect remained for up to 6 weeks. Knock-down of mosquitoes
