Michel Lecoq dedicated over 50 years to the study of locust population dynamics, ecology, monitoring, and control, primarily at CIRAD in Montpellier, where he directed the “Locust Ecology and Control” research unit from 1997 to 2010. A specialist in tropical regions, he conducted extensive fieldwork in numerous countries affected by locust outbreaks. His research greatly advanced understanding of major locust and grasshopper species, including the desert locust, migratory locust, red locust, Mato Grosso locust, and Senegalese grasshopper. He strongly promoted preventive control strategies and analyzed the socio-economic and institutional barriers to their implementation. As a key contributor to the FAO’s EMPRES program (from 1997 to 2010), he supported major reforms of preventive control systems in West and North Africa. Michel Lecoq earned his Ph.D. in entomology from Paris-Saclay University in 1975. Now retired, he continues to serve as an independent consultant. As the author of over 110 scientific articles and 70 books or book chapters, he has served as a consultant for FAO on numerous occasions, was president of the Orthopterists’ Society, and received the D.C.F. Rentz Award in 2010.
