Resarch Themes
Work in progress concerns Lepidoptera drillers (primarily Noctuidae) whose caterpillars drill the inside of the stalks of Poaceae (Gramineae), Cyperaceae, Juncaceae and Typhaceae. Several species, belonging to the genus Busseola, Sesamia and the related genus, are devastating major (20 % of losses on average) cereal crops in sub-Saharan Africa. The economic incidence of each of these species varies according to the big geographical regions and, within these, according to the biotopes. If a lot of studies were dedicated to these insects for more than 60 years, none of them had taken into account the evolutionary dimension, that is the geographical or ecological populational genetic diversity of the main species harmful to the cultures, the story of the distribution and the demography of these populations, the functioning and the evolution of the interactions with their plants hosts. Also, no phylogenetic study had been undertaken on this group of noctuelles. To characterize this diversity and to understand mechanisms at the origin of their evolution will contribute to improve the biological control against these insects.

The researches operations at present pursued in east Africa try to bring part of the answer to the following questions: Are there genetic differences between geographical populations (Western Africa vs East and Southern Africa) or ecological (populations on corn vs wild grasses) as suggest it certain ecological and biological data? Why while the diversity of the group is important, only some species became devastating important of the corn and the sorghum? What is the role of the natural housing environments in the dynamics of infestation of the cultivated plots of land? What are the ecophysiological factors implied in the recognition and the adoption of the host plant ? The acceleration of the degradation and often the disappearance of the natural housing environments almost everywhere in Africa during the last 2 decades isn’t able to favor the passage of certain species confined only in the wild housing environments? The introduction of GMO in Eastern Africa is imminent (the first tries of introduction of transgenic corns are going to begin in 2010 in Kenya): fallow lands rich in wild hosts plants of drillers noctuelles do constitute an effective strategy to protect sensitive genotypes in the African agricultural context? What is going to be the incidence of the global changes (temperature, CO2, anthropisation) on drillers’ communities and interactions with their main natural enemies during the future decades?
