The risk level has increased to THREAT as hopper bands continue to form in Yemen and Mauritania, and an outbreak developed in Eritrea.
Swarms threaten crops in Yemen and an outbreak is developing in Mauritania.
As hopper bands and swarms are forming in the interior where security is poor and control operations are limited, neighbouring countries should be on alert.
The Desert Locust situation has calmed down and only small-scale breeding is expected during the summer; however, increased activity is likely in Yemen where the situation level remains as Caution.
Increased vigilance is required in the Sahel of West Africa and Sudan as well as in Yemen where breeding will occur during the summer.
With hatching and hopper band formation in Israel, the threat of current Desert Locust infestations extends to Israel and Palestine.
The threat declined in the northern Central Region but continues in the spring breeding areas in Sudan, Saudi Arabia, Yemen and Northwest Africa.
As groups and swarms reach the northern Red Sea, there is an increased threat to Israel and Jordan during March.
The risk is concentrated in winter breeding areas on sides of the Red Sea where hopper bands and swarms are present.
