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.
An outbreak developed on the northern coast of the Red Sea in September 2013. A limited second generation of breeding occurred with hatching and band formation in January and February. Thereafter, infestations declined due to control operations, drying conditions and migration. Since the beginning of the outbreak, ground teams have treated more than 150,000 ha.
An outbreak developed on the central coastal plains of the Red Sea as a result of good rains in August and October, followed by two generations of breeding that led to the formation of hopper bands and swarms. Another generation of breeding with egg-laying and hatching occurred in January and February, with potential swarm formation in March. Since the beginning of the outbreak, aerial and ground teams have treated more than 75,000 ha.
Heavy rains associated with a rare Tropical Cyclone in November led to the development of an outbreak on the northwest coast. Hopper bands formed in January and by the end of the month a few small adult groups and swarmlets moved to Djibouti. More hatching and band formation occurred in February, and swarms formed in March that left the coast, moving up the escarpment to the plateau and eastern Ethiopia. Limited ground control operations using biopesticides were carried out in late February.
Since 11 March, immature swarms began to appear in the eastern region near Jijiga and Ayasha. The swarms originated from an outbreak on the northwest coast of Somalia where local breeding caused hopper bands and swarms to form in February and March. The swarms left the coast as vegetation dried out, moved up the escarpment and crossed the dry Somali plateau to eastern Ethiopia where they are expected to concentrate in areas of recent rains between Jijiga, Dire Dawa and Ayasha, mature and lay eggs.
