GROUPS FORM IN MAURITANIA In October, locust populations increased in Mauritania, where solitarious and transiens breeding occurred in the northwest and a few groups of adults and hoppers formed. Solitarious adults were present in the north of the country and in Chad, while no locusts were seen in central Algeria, Western Sahara and Tunisia. No surveys were carried out in Libya, Mali and Niger. In the Central Region, a few isolated adults were seen in southern Egypt, and no locusts were seen in Sudan, Ethiopia, Somalia, Saudi Arabia, Yemen and Oman. During the forecast period, breeding will continue in northwest Mauritania, where more hopper groups and bands will form, and fledging will lead to the formation of more adult groups. A second generation of breeding could start from late November. Breeding will probably occur in northern Mali, Western Sahara and southern Algeria, where hopper groups and bands may form. Solitarious breeding might have occurred, after good summer rains, in northern Mali, Niger and Chad, and southern Algeria, and groups may form. Consequently, locust populations will increase further, and outbreaks could develop in central and northern Mauritania, northern Mali and Niger, Western Sahara and southern Algeria. Surveys should be increased, and control operations will be required in Mauritania, while surveys should be resumed in northern Niger, Chad and southern Algeria. In the Central Region, small-scale breeding is likely to start on the Red Sea and Gulf of Aden coastal plains where recent rainfall occurred, but no significant developments are expected. In the Eastern Region, no locusts were seen in India and Iran, and no significant developments are expected.
