31 May 2005. Immature swarms move into western Darfur Five immature swarms appeared near Geneina in western Darfur, Sudan on 25 May. They were seen flying from the west towards the east, suggesting that these are probably the same swarms that were reported earlier in the month in southern Niger and western Chad. They are likely to have moved across Chad on winds associated with the Inter-Tropical Convergence Zone - the so-called Southern Circuit migration. As conditions are still dry and rains have just started in western Darfur, these swarms could move further east to Northern Kordofan and the Nile River, perhaps reaching Kassala and the western lowlands in Eritrea. In Saudi Arabia, control operations continue against late instar hopper bands. Those infestations that are not treated could form a few small adult groups in the coming weeks that would eventually move to Sudan. Local breeding and band formation continues in the Tanout region in central Niger. Local breeding is also underway in southern Algeria near Tamanrasset and could be in progress in northern Mali. Ground control operations continue against a few late instar hopper bands and new adults in northeast Algeria near El Oued. Regular and intensive survey efforts are required in Mauritania, Mali, Niger and Chad during the coming months.
