Ces travaux montrent la pertinence et l'utilité de la modélisation du cytosquelette des cellules par systèmes mécaniques précontraints. Ces recherches s'inscrivent dans le champ de la biomécanique cellulaire et tissulaire et deux applications sont proposées. On présente tout d'abord la recherche de forme d'une cellule isolée par modèles de tenségrité non réguliers, puis on propose une combinaison entre les modèles granulaires et l'analogie de tenségrité. L'extension prospective aux assemblages multicellulaires avec notion d'autocontrainte partagée, par modèles de grilles de tenségrité est ensuite présentée.

—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.
