General Situation during October 2014
Forecast until mid-December 2014

An outbreak developed during October in Sudan where intensive aerial and ground control operations were mounted against hopper bands and adult groups. Some adults moved to winter breeding areas along the Red Sea coast where they laid eggs. A few adult groups appeared in southern Egypt and limited control operations were carried out along the Nile. Breeding commenced on the coast of Eritrea and southern Yemen while scattered adults were present along the Nile. Breeding commenced on the coast of Eritrea and southern Yemen while scattered adults were present along the Red Sea coast in Saudi Arabia and Yemen. Ground teams treated a few hopper bands and swarm lets that persisted in northeast Ethiopia. Although the situation was calm in the the Western Region where small-scale breeding occurred in Mauritania, Niger and Chad, locust numbers may be increasing in western Mauritania. In South-West Asia, a few locusts persisted in the summer breeding areas along both sides of the Indo-Pakistan border. During the forecast period, strict vigilance is required along both sides of the Red Sea where locusts numbers will increase in Egypt, Sudan, Eritrea, Saudi Arabia and Yemen.

Western Region. The situation remained calm in October. Although small-scale breeding occurred in western Mauritania, central Niger and in Chad, locust numbers remained low except in western Mauritania where they started to increase at the end of the month. In Northwest Africa, a few adults were seen in Morocco and central Algeria. During the forecast period, locust numbers will increase in west and northwest Mauritania as a result of local breeding that could lead to the formation of small groups of hoppers and adults. Low numbers of adults will persist in parts of northern Mali, Niger and northeast Chad.

Central Region. A small outbreak developed during October in Sudan where hopper bands and adult groups formed in the summer breeding areas from north of Khartoum to the Red Sea Hills. Populations were starting to shift to the winter breeding areas where adults appeared in the northeast and on the Red Sea coast where they laid eggs. Ground and aerial teams were mobilized and treated 20,000 ha. Immature adult groups also appeared in southern Egypt and limited control operations were undertaken near Abu Simbel. More groups and perhaps a few small swarms are likely to form in November and move to the Red Sea coastal plains and subcoastal areas in Sudan and southeast Egypt where breeding will occur. Small-scale breeding started on the Red Sea coast in Eritrea where limited control operations were carried out. In northeast Ethiopia, control teams treated a few late instar hopper bands and small swarmlets that formed in areas of previous breeding. Low numbers of adults were present along parts of the Red Sea coast in Saudi Arabia and Yemen, and small-scale breeding was in progress on the Gulf of Aden coast. During the forecast period, breeding will cause locust numbers to increase along both sides of the Red Sea in Egypt, Sudan, Eritrea, Saudi Arabia and Yemen.

Eastern Region. The situation remained calm in October. Locust numbers declined along both sides of the Indo-Pakistan border as vegetation continued to dry out. No significant developments are likely.
