The Commission for Controlling the Desert Locust in the Central Region
DL Situation
Desert Locust Bulletin, No. 535, April 2023


The Desert Locust situation continued to remain calm during April. A small outbreak developed from spring breeding in two areas on the Red Sea coast of Saudi Arabia during March and increased in April. By the end of the month, there were late instar hopper groups, bands, and new immature adult groups as well as considerable air and ground control operations. During the forecast, immature adults and groups are expected to move into the interior of Saudi Arabia in early May where there was good rain in April. The adult groups will mature and lay eggs for another generation of breeding. Hatching could start in the second half of May. In Northwest Africa, small hopper groups and bands occurred south of the Atlas Mountains in Morocco as well as further south in Western Sahara, and control was carried out. During the forecast, vegetation will start to dry, and the new immature adults will form small groups and move south. Weather models suggest that the summer season rains may start in the Sahel during June this year. Elsewhere, low numbers of adults were present in Yemen, southeast Egypt, northwest Somalia, and southwest Pakistan. During the forecast period, small-scale breeding may occur in Yemen, southeast Iran, and southwest Pakistan.
