The relative speed of food transit in the larval alimentary canal of different species of the S. damnosum complex in West Africa was studied. Each is adapted to a particular biotope. Some are more widespread. Sex has no influence. Typical forest species (S. yahense and S. sanctipauli) present a slower transit than S. sirbanum, a typical savanna species. This transit is slower in S. damnosum s.s., a savanna species adapted to the forest, than in S. sirbanum. This similar to S. soubrense, a forest species adapted to savanna, in comparison with forest species. S. sanctipauli-S. soubrense heterozygotes are intermediate between the 2 spp. from which they originated.
