The International African Migratory Locust Organization (OICMA) was founded 13 July 1955, with a Secretariat-General at Nogent-sur-Marne (France). Its aim was to "exercise continuous surveillance and preventive control of the African migratory locust in the outbreak area on the River Niger, destroy concentrations of the locust, carry out research and develop means of control." This control was effective, and increasing dryland farming and better monitoring in Mali changed the character of the outbreak area such that by the 1980s, the insect's behaviour was thought to be more like that of a solitary grasshopper than a gregarious locust. OICMA was dissolved in 1986. https://en.wikipedia.org/wiki/African_migratory_locust#Locust_control_organisations
