Three controlled -release personal-use pulp fabric impregnated insect repellent formulations of 5% N,N-diethyl-3-methylbenzamide (DEET), and 10% and 15% neem oils were evaluated in an environmental chamber on volunteers for their repellent efficacy against three mosquito species, Culex pipiens pallens, Aedes aegypti and Ochlerotatus togoi. The 5% DEET formulation showed significant repellency in pulp fabric (5㎜ in width) against Culex pipiens pallens and Aedes aegypti (P less than 0.05), providing an average repellency of 88.0%, 66.3%, and 46.8% of Cx. pipiens pallens, Ae. aegypti and O. togoi bites, respectively, during the 6 hours of exposure period.
