Desert Locust Bulletin 482 (November 2018) [EN/AR]

General situation during November 2018 Forecast until mid-January 2019

The Desert Locust situation continued to remain calm during November

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 last week 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. In the Western Region, small-scale breeding caused locust numbers to increase slightly 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 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. Small-scale 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.
