General Situation during August 2010
Forecast until mid-October 2010

The Desert Locust situation remained calm during August despite good rainfall throughout the summer breeding areas in the Sahel of West Africa and Sudan as well as along both sides of the Indo-Pakistan border. Small-scale breeding occurred in Mauritania and in Pakistan, and is likely to be underway in parts of Mali, Niger, Algeria, Chad, Sudan, Eritrea, and India. During the forecast period, small-scale breeding will continue in these areas and locust numbers could increase rapidly. By mid-October, there is a low risk that locusts could concentrate in vegetation that remains green and form small groups. All efforts should be made to conduct regular surveys during the next few months to monitor the situation.

Western Region. Good rains fell during August for a second consecutive month in the summer breeding areas of the northern Sahel between Mauritania and Chad. Small-scale breeding occurred in southeast Mauritania and is likely to be in progress in northern Mali and Niger (but surveys could not confi rm this because of continued insecurity), in southern Algeria and in eastern Chad. During the forecast period, small-scale breeding will continue in the northern Sahel and locust numbers could increase rapidly. By mid-October, there is a low risk that locusts could concentrate in vegetation that remains green and form small groups, primarily in northwest Mauritania and to a lesser extent in other areas of northern Mali and Niger.

Central Region. Good rains fell during August for a second consecutive month in the summer breeding areas of northern Sudan, western Eritrea and the interior in Yemen. Only scattered solitarious adults were seen in Sudan. A few hoppers and adults were present in eastern Ethiopia from undetected breeding in July. During the forecast period, small-scale breeding will cause locust numbers to increase in the interior of Sudan and western Eritrea and, to a lesser extent, in the interior of Yemen. Low numbers of solitarious adults could appear in areas of recent rainfall on the Red Sea and Gulf of Aden coasts in Yemen and on the plateau in northern Somalia.

Eastern Region. Good rains associated with the monsoon fell during August for a second consecutive month throughout the summer breeding areas along both sides of the Indo-Pakistan border. Low numbers of adults were present between Tharparkar and Cholistan in Pakistan and small-scale breeding was reported. So far, breeding has not been detected in adjacent areas of Rajasthan, India. During the forecast period, small-scale breeding will cause locust numbers to increase in both countries.
