Locusts move to winter breeding areas
The Desert Locust situation remains calm in all countries.
In the Central Region, adults and a few small groups moved from the summer breeding area in eastern Sudan to the Red Sea coastal plains and northeastern subcoastal areas of Sudan. Low numbers of adults were present on the coast of Eritrea and Saudi Arabia. As good rains fell along both sides of the Red Sea, small-scale breeding was already underway in Eritrea and commenced during the last week of November in Sudan. Local breeding also occurred along the edge of the Empty Quarter in southern Oman where good rains fell in October from Cyclone Luban. During the forecast period, small-scale breeding will cause locust numbers to increase on the coastal plains along both sides of the Red Sea from southeast Egypt to central Eritrea and from northern Saudi Arabia to southwest Yemen. Small-scale breeding may also occur along the Gulf of Aden coastal plains in southern Yemen and northwest Somalia if more rains fall. Limited breeding may continue in southern Oman.
In the Western Region, small-scale breeding caused locust numbers to increase in western Mauritania, northern Mali and Niger, and southern Algeria near the Niger border. Groups formed in northeast Mali and southern Algeria, and ground teams treated 130 ha in southern Algeria. A few residual summer-bred populations of solitarious adults remained in northeast Chad. During the forecast period, small-scale breeding is likely to continue in Mauritania and may extend to the north of the country and to adjacent areas of Western Sahara, causing locust numbers to increase.
In South-West Asia, no locusts were reported and no significant developments are likely.
