The diversity of the populations of Busseola fusca

Busseola fusca is a pest of cultivated cereals. It belongs to a genus widespread in Africa and Asia. It is morphologically similar all over its range of distribution.

The molecular analysis of the Cytochrome b gene revealed the diversity of the populations. Three groups of populations have been documented. They probably diversified around 1 million years BP. The Cameroon population belongs to an East african subgroup and is not linked to the populations from West Africa .
