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.
Field operations continue against an outbreak on the northern coast of the Red Sea that developed in September 2013. In the past month, a limited second generation of breeding occurred with hatching and band formation. Late instar hopper bands declined in February as they fledged and an increasing number of immature adult groups formed. As good rains fell at mid-month, the adults were maturing and laying eggs. Since the beginning of the outbreak, ground teams have treated more than 50,000 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 occurred in February and ground control operations were being organized.
