The efficacy of triflumuron was tested on three types of textiles (cotton, polyester and polypropylene) of two colours (blue and black) for application in self-sterilisation of Glossina palpalis gambiensis Vanderplank, 1949 (Diptera: Glossinidae). Three concentrations of triflumuron diluted with water to 3,6 and 12 % were used to impregnate each type of cloth and two groups of tsetse flies were contaminated—females aged 20 days were directly contaminated by exposure to impregnated cloth; and younger females (3-days-old) were contaminated during the mating by males treated like old females. The blue and black-coloured cloths had no significant differences in terms of reproductive parameters (P<0.05). On the other hand the type of fabric and the concentration of triflumuron had significant effects on the efficacy of the product. Cotton and polypropylene, impregnated with triflumuron diluted to 6 and 12 % respectively sterilised the old females on 5 consecutive reproductive cycles from normal pupa production. The two concentrations also sterilised the younger females on 3 consecutive reproductive cycles from pupal hatching. Polyester impregnated with the same concentrations sterilised the old females during the 3 first reproductive cycles after treatment and young females on 2 reproductive cycles.
