Desert Locust Bulletin, No.456, September 2016
The Desert Locust situation remains very serious in Yemen and there are signs that an outbreak is developing in northwest Mauritania.
In Yemen, hopper groups, bands and adult groups continue to form in the interior and on the southern coast. Only limited survey and control operations could be carried out due to insecurity. An increasing number of adults appeared on the Red Sea coast of the country, and ground and aerial control operations treated 3,000 ha of hopper groups, bands and adult groups in adjacent coastal areas of Saudi Arabia. More adult groups and perhaps a few small swarms are expected to form in southern Yemen and will move to the Red Sea coast of Yemen and Saudi Arabia, and perhaps cross the Gulf of Aden to the Horn of Africa in northern Somalia, Djibouti and Ethiopia. Breeding will cause a further increase in locust numbers in the coming months.
In Mauritania, there was a sudden increase in locust densities in the summer breeding areas of the south, causing adult groups to form from mid-September onwards. An increasing number of adults and groups subsequently appeared in the northwest where they laid eggs. Hatching is imminent and an outbreak is likely to develop by mid-October, with a possibility of small hopper bands and swarms.
As vegetation dried out elsewhere in the summer breeding areas of the northern Sahel in West Africa and Sudan, a few groups formed in western Mali, northeast Chad and the interior of Sudan. Large numbers of grasshoppers were also present in several countries.
In Southwest Asia, the situation remains calm.
