Outbreaks
Outbreak areas have been identified in Zambia, Tanzania, Malawi and also Madagascar and Réunion. In the Sahel, the species is observed on a more incidental basis in Cape Verde, the central Niger River delta in Mali and around Lake Chad. The last widespread plague occurred from 1930-1944, when almost all of southern Africa was invaded.
After unsuccessful efforts to control the locusts through environmental modifications, chemical agents are currently being used. A biological product based on an entomopathogenic fungus (Metarhizium acridum) is now available (see desert locust). It has been successfully tested on both nymphs and adults of the red locust.
