[Biometrical identification of larval instars of S. damnosum s.I. and S. adersi (Diptera: Simuliidae) (author's transl)].

The biometrical analysis of two characters measured on the postgenae of Simulium larvae allow to differentiate the seven larval instars of S. damnosum s.I. and S. adersi, and to draw the growth curves of one parameter for the different instars.
