The termite species Macrotermes bellicosus has a vast geographical distribution, which can produce genetic divergence in populations that evolve in its different environments. Experiments carried out on digestive oxidases in two populations of M. bellicosus originating from Chad and from Côte d'lvoire showed differences in the rate of their enzymatic activities. Populations from Côte d'lvoire showed significantly higher degradation activity against fresh vegetal matter than populations from Chad.
