Abstract

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.

Résumé

Le termite Macrotermes bellicosus présente une vaste aire de répartition qui peut entraîner des divergences génétiques pour les populations les plus éloignées. L'analyse des activités osidasiques et de certaines enzymes du métabolisme chez deux populations de M. bellicosus, l'une originaire du Tchad et l'autre de la Côte d'lvoire, montre qu'il existe des differences quantitatives entre leurs activités enzymatiques. Les populations de Côte d'lvoire dégraderaient plus facilement la matière végétale fraiche que celles du Tchad.
