  3. Objectives • To establish surveys along the VLC • To understand the high biodiversity of the VLC and the surroundings areas and the biogeography of the taxa involved • To include ecological, biological, geographical and genetic results into a single framework

  4. The 25 hotspots of biodiversity to preserve in the world, according to Myers et al. (Nature, 24 March 2000) Western African forests Cameroon volcanic line (CVL)

  8. 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.

  9. 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 .

  10. GIS Data are linked in a single type of GIS database which will use the 200 different maps from the IRD collection (Bondy France). The GIS grouped taxonomic (with collection access code), geographical (altitude, longitude, latitude) genetic access code, biological data (e g. hostplant).
