Acc. to FAO: Local breeding is in progress in a few places in NW Africa. In NW Mauritania, low numbers of solitarious hoppers are present. South of the Atlas Mountains in Morocco, hatching is expected this week near the border with Algeria. In the eastern Sahara in Algeria, ground teams treated 20 ha of hoppers. Isolated adults are present in northern Mauritania and Mali. Unless further rains fall, adults will eventually start to move towards the summer breeding areas in the northern Sahel during May and June. The scale of this movement will be very limited. Elsewhere, ecological conditions are dry and no locusts have been reported. Nevertheless, some locusts are likely to be present and may be breeding in Yemen where unusually good rains fell in early April. No significant developments are expected in the coming weeks.
