An overview of current Desert Locust outbreaks and other important infestations that pose a potential threat to agriculture and food security is presented. Select the particular threat from the list on the left for more details. The threats are updated on a regular basis as new information and data arrive at FAO and are analysed by DLIS. Once the threat has passed, the information can be found in the Archives section.
Ground control teams are treating hopper bands and adult groups on the northern coast of the Red Sea in Yemen. Most of the hoppers have fledged and at least one immature swarm has formed. A second generation of breeding is now underway. Hatching will cause locust numbers to increase from early December onwards and hoppers will form bands. Smaller infestations that are present on the central Red Sea coastal plains and the Gulf of Aden coast are likely to increase. All efforts are required to contain the current situation and prevent it from spreading within the Region.
An outbreak developed in northwest Mauritania during October due to good rains and the arrival of adults from the summer breeding areas. Control operations have intensified recently against hopper groups and bands as well as groups of adults. A second generation of breeding is expected to occur in December and cause locust numbers to increase further. Infestations are dispersed over an estimated area of about 120,000 km2. Ground control operations commenced in early October and have treated more than 35,000 ha so far.
An outbreak developed in November on the central coastal plains of the Red Sea as a result of good rains in August and October, followed by undetected breeding. Ground teams treated 10,000 ha of hopper bands and adult groups that formed in November. Aerial control operations started in early December. Small swarms may form in December, mature and second generation laying could start in late January. All efforts are required to undertake regular surveys and contain the current situation to prevent it from spreading within the Region.
