General Situation during January 2012
Forecast until mid-March 2012

The Desert Locust situation continued to remain calm in January. Small-scale breeding occurred in parts of southeast Algeria, southwest Libya and northern Niger. Limited ground control operations were carried out in Algeria. Very few locusts were present in the winter breeding areas along both sides of the Red Sea and Gulf of Aden because of poor rainfall and dry vegetation. Only scattered adults were reported in Sudan and Saudi Arabia. During the forecast period, breeding will end in the winter breeding areas but limited breeding could continue along the Algerian-Libyan border and in northern Niger. Close monitoring is required in these three countries. Spring breeding may commence in Baluchistan of western Pakistan and southeast Iran if good rains fall in February and March. No signifi cant developments are likely.

Western Region. Mainly dry conditions prevailed during January and very little rain fell except in Niger and in the northern Sahara in Algeria. Very localized small-scale breeding occurred in southwest Libya and, to a lesser extent, in southeast Algeria and northern Niger. Small patches of gregarious hoppers formed in Libya and control operations were being organized. In Algeria, ground teams treated 85 ha. Elsewhere, isolated adults may be present in parts of northwest Mauritania and in northern Mali but surveys were not carried out to confi rm this. During the forecast period, breeding may continue in currently infested areas although more rains must fall before locusts increase in number. All efforts are required to monitor the situation closely in Algeria, Libya and Niger.

Central Region. Low numbers of solitarious adults persisted during January in a few places of the winter breeding areas along both sides of the Red Sea in Sudan and Saudi Arabia. Similar populations may be present in coastal areas of Eritrea, Yemen and eastern Oman. No locusts were reported in Egypt, Ethiopia and northern Somalia. During the forecast period, small-scale breeding may occur during February along both sides of the Red Sea and on the eastern coast of Oman but this will decline from March onwards unless further rains fall. No significant developments are likely in the region.

Eastern Region. Dry conditions prevailed throughout the region during January. Isolated solitarious adults were seen at one place on the coast in western Pakistan. Small-scale breeding is likely to take place in the spring breeding areas of western Pakistan and southeast Iran if light to moderate rains fall during the forecast period. Nevertheless, locust numbers will remain low and below threatening levels. No locusts were seen during routine surveys in western India. No significant developments are likely in the region.
