Desert Locust Bulletin No. 565: General situation during October 2025 - forecast until mid-December 2025
Global Food and Nutrition Security

In October, the locust outbreak intensifi ed in Mauritania and spread into Western Sahara, where adult groups migrated and bred across an 800 km stretch from south to north. New hopper groups and a few bands appeared from the second generation of breeding in western Mauritania. Scattered and isolated adults and hoppers were observed in several locations in Chad. Isolated adults were found in Algeria, where a few adult groups were also reported at the end of the month. Ecological conditions remain favourable for breeding in Mauritania and Western Sahara, where hopper groups and bands are expected to continue increasing during the forecast period. Adult groups and small swarms are likely to appear in November. Some adult groups may also appear in Mali, Niger, Chad, Morocco and Algeria. Continued surveillance will be essential, and control measures will be required. In the Central Region, isolated and scattered adults were present in Sudan, and a few isolated adults were observed in Egypt, Saudi Arabia and Yemen, where a few hoppers were also present. Small-scale breeding may occur if additional rainfall happens. A few groups may appear in Sudan in November. In the Eastern Region, no locusts were found, and no signifi cant developments are expected.
