for the control of vectors. This however involves prior entomological evaluation of the

efficacy of the repellents and the repellency generated by innovative textiles already incor-

porated with repellents against vectors. Guidelines involving the testing of the efficacy of

repellents has been laid down by the WHO (2009) but requirements for registration are still

subject to national regulatory authorities of the particular country or territory in question.

In this study, the cage test method was used to determine the efficacy of four se-

lected repellents impregnated on textiles. Results from this study has shown the validity

of protocol The conventional impregnation and coating method in addition to an innova-

tive technology based on prior modification of fabric using Limonene as insecticide has

been reported (Hebeish, Moustafa, Fouda, Hamdy, EL-Sawy, Abdel-Mohdy 2008). The

procedure for running repellents efficacy tests has been reported by a few other studies but

based mostly on topically applied repellents (Barnard Donald Roy, Ulrich Bernier, Rui-De

Xue and Mustapha Debboun 2007).
