About us

Thierry Hance Led by Thierry Hance, the laboratory of "Ecology of interactions and biological control" focuses on biodiversity and how species interact with each other and with their environment. We study the evolution of trophic systems through relationships between plants, herbivorous insects, symbiotic bacteria and natural enemies. Our research projects combine fundamental ecology (physiology, behavioral and social) and applied ecology (biological control mainly against pests in agriculture) and are part of both fundamental and industrial approaches. The results are used to understand co-evolutionary processes and develop new crop protection systems. 


With 20 members (lab technicians, phD students, Researchers), our team is supported by funding from F.R.S-FNRS, la DGTRE (Région Wallone), la DGA (Région Wallonne), la politique scientifique fédérale, la Coopération Technique Belge, L’UCL.
