In 1964 the Republic of Mali issued three
stamps commemorating the formation of the Organization
Internationale Contre le Criquet Migrateur Africain,
(International African Migratory Locust Organization).
The Locusta Migratoria Migratoriodies, the
African Migratory Locust, has been a problem for centuries. (This
is the locust mentioned in Exodus.) In 1962, 21 African countries
formed the OICMA to control the locust. The words at the bottom of the
stamp, “Aire d’invasion du croquet migrateur Africain” (area of the
invasion of the African migratory locust), refer to the map showing
the spread of the locust invasion from 1928 to 1942 in darker green.
There are two errors on the stamp. The first is the misspelling of “Locusta”
as “Logusta. The second is “Kara,” which does not exist at the
marked location unless it is a misspelling for “Kabara.”
