My research focuses on the genetic diversity, genetic structure and ecology of insects – often invasive species – that are of agricultural or forestry interest, either because of the damage they cause to crops or forests, or because of their natural ability to control (e.g. parasitoids, predators) populations of these harmful insects.

In collaboration with my partners in the Global South, mainly in West Africa, the aim is:

1. to characterise, from a biological, genetic and ecological perspective, these species and their populations, and/or communities of species associated with key crops (e.g. tomatoes, wheat) or forest tree species (e.g. acacias of the Great Green Wall),
2. to test methods of biological control,
3. to gain a better understanding of the key factors underlying the diversity patterns of the targeted biological models and their impacts on ecosystems, with a view to ultimately providing useful insights for their sustainable management in the study areas (e.g. Niger, Senegal).
