Michel Lecoq has conducted research primarily centered on the population dynamics and ecology of various pest locust and grasshopper species, such as Desert, Migratory, Red, Italian, and Mato Grosso locusts, along with the Senegalese grasshopper. His work spans 98 scientific publications and 59 books or book chapters. His contributions have been pivotal in developing preventive control strategies, notably against Desert locusts in Africa (in collaboration with FAO), Mato Grosso Locusts in Brazil (with EMBRAPA), and Migratory locusts in Madagascar (in partnership with FAO, FOFIFA, and the National Locust Center). He actively participated in FAO's EMPRES program for strengthening preventive control, aiding in program formulation, fundraising from international donors, and contributing to program activity planning as a Consultative Committee member. Additionally, he played a key role in studies and expert missions that led to significant institutional reforms governing preventive control of this species in West and North Africa, emphasizing ongoing interest in perceiving and addressing obstacles—sociological, financial, and legal—hindering effective control. His endeavors resulted in numerous consultation reports and many papers aimed at broader public understanding.
