Research activity

I work on the pest of bananas and plantains. My main actual focus is the study of the arthropod communities and their relationships between the vegetal diversity in tropical agroecosystems. However, I try to work on the different biological agents of these agroecosytems and used modelling tools to integreate ecological processes observed in the field to improve my understanding of ecosystem functionning.

Ant communities in tropical agroecosystems

When you are working on tropical agroecosystems, you are rapidly facing a particluar and very interesting group of arthropods, the ants.

Ants are preponderant in tropical agroecosystems and their influence on the functionning of arthropod communities cannot be ignored. By their ubiquity and abundance, ants represent an important group of potential agents of biological control.

I conduct field studies in Martinique, Costa Rica and Cameroun to assess such potential in a context of ecological diversification of agroecosystems.

Ants in Martinique

I started to interest in antsby working in banana fields in Martinique. Here is a list of ant species that are encountered in Martinique agroecosystems. With 43 identified species, this list is very likely incomplete and should be regularly updated. Please contact me if you have specimens of ants of Martinique.
