Noctuid Stem Borers Biodiversity in Africa (NSBB): A Joint IRD (France)-icipe Programme

Print PDF

The NSBB team is part of an IRD Research Unit, which is part of the recently established French Institute for the Diversity, Ecology and Evolution of the Living World (IDEEV) that brings together scientists from French institutions (IRD, CNRS and INRA) and a French University (Paris XI-Orsay University). The research programme of our IRD Research Unit focuses on the response of tropical insects to global changes and on biodiversity and evolution of insects.Tropical insects, like those of other parts of the world, respond to global change, which can be the result of direct anthropogenic effects on tropical ecosystems (wild habitat fragmentation and destruction) or of indirect consequences of human activities (global warming and increased atmospheric CO2 concentration). Our research programme aims at characterising and quantifying these responses to allow for estimating their ecological consequences on entomological communities, habitats, landscapes and agro-ecosystems. In this context, the main research activities of the NSBB team at icipe encompass:

  • the characterisation of global changes in two main regions (Africa and South America) where drivers gradients have been established,
  • to study the effect of these factors on insects at the level of individuals, populations and communities, and
  • to integrate these results into predictive models.

Project Activities

  • Biodiversity of lepidopteran stemborers and their natural enemies in wild habitats surrounding cereal crops in Austral Africa (South Africa, Mozambique)
  • Genetics of the acclimatisation of Kenyan strains of Cotesia sesamiae in Cameroon
  • Insects adaptation to anthroposystems
  • Predicting climate change that induced vulnerability of cereal crops to Busseola fusca and Chilo spp. and their main natural enemies through advanced insect phenology modelling
  • Chemo-ecological functioning of noctuid gramineous stemborer communities in East Africa
