In May 2026, desert locusts mainly distributed the central-southwestern regions of Morocco, localized northwestern and central areas of Algeria, and the southern inland areas of Yemen, affecting 88.3, 25.1, and 16.6 thousand hectares of vegetation, respectively. In Morocco, spring breeding entered its late stage. Previous wet conditions promoted sustained vegetation greening in central-southwestern areas, while more immature adult groups formed following hopper groups fledging. The affected area expanded slightly from April and extended eastward and southward along the Draa Valley and southern desert margins. Some locust populations may subsequently move east into suitable areas of western Algeria, while others may move south into Mauritania and Sahel summer breeding areas. In Algeria, localized locust populations were relatively dense in the northwest under the combined influence of influxes from Morocco and suitable vegetation conditions. Sporadic populations increased along the central-southern desert margins, indicating a shift from the northwest toward central-southern suitable patches. In Yemen, small oases and wadi habitats remained in the southern Gulf of Aden coastal plains and inland transition zones; together with the possible southward movement of sporadic adults from late spring breeding areas in inland Saudi Arabia, this maintained low-density localized activity.

In April 2026, desert locusts mainly affected the central-southwestern regions of Morocco, localized northwestern areas of Algeria, and the northern inland areas of Saudi Arabia, affecting 84.8, 20.9, and 18.5 thousand hectares of vegetation, respectively. Due to northward migration and favorable breeding conditions, Morocco's affected area expanded by approximately 20.0 thousand hectares, spreading from the southwest to the center. In Algeria, the affected area remained concentrated in the northwest and largely stable compared to last month; although local risks increased due to minor external inputs and spring greening, overall expansion remained limited. In Saudi Arabia, locusts were mainly in the northern inland, with the affected area expanding slightly while maintaining a stable, low-level epidemic.

In March 2026, desert locusts mainly affected the central-southwestern regions of Morocco, localized northwestern areas of Algeria, and the central-northern inland areas of Saudi Arabia, affecting 64.3, 21.7, and 18.1 thousand hectares of vegetation, respectively.

In February 2026, desert locusts were mainly distributed in the central-southwestern regions of Morocco, localized western and southern areas of Algeria, and the upper Nile Valley corridor and southern inland areas of Egypt, affecting 61.9, 20.4 and 18.4 thousand hectares of vegetation, respectively.

In January 2026, desert locusts were mainly distributed in the upper Nile Valley corridor of Egypt, the southwestern Red Sea coastal zone of Saudi Arabia, and the southern Gulf of Aden coastal plains of Yemen, affecting 15.7, 19.2 and 21.2 thousand hectares of vegetation, respectively. 

In December 2025, desert locusts were primarily distributed in the Nile Valley irrigation zone and the southern border areas of Egypt, the central-to-southern Red Sea coastal zone of Saudi Arabia, and the southern Gulf of Aden coastal plains of Yemen, affecting 17.0, 18.5, and 22.2 thousand hectares of vegetation, respectively. 

In November 2025, desert locusts were primarily distributed in northwestern Somalia, the southwestern Red Sea coastal zone and neighbouring mountains of Saudi Arabia, and the western Red Sea coast–southern Gulf of Aden coast in Yemen, affecting 15.2, 19.1, and 21.1 thousand hectares of vegetation, respectively.

In October 2025, desert locusts were primarily distributed along the upper Nile Valley corridor and adjacent areas in Egypt, the southwestern Red Sea coastal zone and neighbouring mountains in Saudi Arabia, and the western Red Sea coast and southern Gulf of Aden coast in Yemen, affecting 15.3, 17.1, and 18.7 thousand hectares of vegetation, respectively.

In September 2025, desert locusts were primarily distributed across the central–western interior of Eritrea, the western Red Sea coastal zone and the southern interior of Saudi Arabia, and the southern Gulf of Aden coast of Yemen, affecting 15.2, 16.8, and 17.9 thousand hectares of vegetation, respectively. 

In August 2025, desert locusts were primarily distributed in the central Nubian Desert and the southern Toshka irrigation area of Egypt, the western lowland corridor of Eritrea, and the western Red Sea coastal provinces of Yemen, affecting 15.7, 13.9, and 17.2 thousand hectares of vegetation, respectively.

In July 2025, desert locusts were primarily distributed in the western desert and the central Nile Valley of Egypt, the inland regions from southern to northern Saudi Arabia, and the eastern plains and the southeastern desert fringe of Pakistan, affecting 17.1, 16.2, and 14.4 thousand hectares of vegetation, respectively.

In June 2025, desert locusts were primarily distributed in the western desert and the central Nile Valley of Egypt, the northwestern coastal and adjacent plateau areas of Somalia, and the northern and central inland areas of Saudi Arabia, affecting 15.7, 14.7, and 17.8 thousand hectares of vegetation, respectively.
