Research interests and expertise

The sustainability of agricultural production requires ecological management practices based on thorough understanding of epidemiological processes.  Most control strategies currently focus on the temporal aspect of epidemics, regardless of the spatial mechanics.  And designing innovative pest management strategies incorporating the spatial aspect of epidemics involves thorough knowledge about the life-history traits of the pathogen or pest.

My current work lies in producing knowledge to design innovative pest and disease management strategies that allow to reduce reliance on pesticides.

Current and recent activities

Project coordination

• STARTAUP (FRB, 2018-2020, R. Le Cointe/S. Poggi) : Design of alternative strategies for controlling wireworm damage in maize crops. The STARTAUP project aims to produce knowledge about the biological and ecological processes determining the level of wireworm infestation and the associated damage in maize crops for the purpose of developping innovative control strategies https://www6.inra.fr/startaup/.

Project membership

• ElatPro (ERA-NET C-IPM, 2016-2019): Spotting the needle in a haystack - Predicting wireworm activity in top soil for integrated pest management in arable crops.
• SYSBIOTEL (ANR, 2009-2012): Integrated management of soil-borne bioagressors in vegetable cropping systems
